CHIEF JUSTICE ROBERTS delivered the opinion of the Court.
Article 36 of the Vienna Convention on Consular Relations (Vienna Convention or Convention), Apr. 24, 1963, [1970] 21 U. S. T. 77, 100-101, T. I. A. S. No. 6820, addresses communication between an individual and his consular officers when the individual is detained by authorities in a foreign country. These consolidated cases concern the availability of judicial relief for violations of Article 36. We are confronted with three questions. First, does Article 36 create rights that defendants may invoke against the detaining authorities in a criminal trial or in a postconviction proceeding? Second, does a violation of Article 36 require suppression of a defendant‘s statements to police? Third, may a State, in a postconviction proceeding, treat a defendant‘s Article 36 claim as defaulted because he failed to raise the claim at trial? We conclude, even assuming the Convention creates judicially enforceable rights, that suppression is not an appropriate remedy for a violation of Article 36, and that a State may apply its regular rules of procedural default to Article 36 claims. We therefore affirm the decisions below.
I
A
The Vienna Convention was drafted in 1963 with the purpose, evident in its preamble, of “contribut[ing] to the development of friendly relations among nations, irrespective of their differing constitutional and social systems.” 21 U. S. T., at 79. The Convention consists of 79 articles regulating various aspects of consular activities. At present, 170
Article 36 of the Convention concerns consular officers’ access to their nationals detained by authorities in a foreign country. The article provides that “if he so requests, the competent authorities of the receiving State shall, without delay, inform the consular post of the sending State if, within its consular district, a national of that State is arrested or committed to prison or to custody pending trial or is detained in any other manner.” Art. 36(1)(b), id., at 101.1 In other words, when a national of one country is detained by
“The rights referred to in paragraph 1 of this Article shall be exercised in conformity with the laws and regulations of the receiving State, subject to the proviso, however, that the said laws and regulations must enable full effect to be given to the purposes for which the rights accorded under this Article are intended.” Art. 36(2), ibid.
Along with the Vienna Convention, the United States ratified the Optional Protocol Concerning the Compulsory Settlement of Disputes (Optional Protocol or Protocol), Apr. 24, 1963, [1970] 21 U. S. T. 325, T. I. A. S. No. 6820. The Optional Protocol provides that “[d]isputes arising out of the interpretation or application of the Convention shall lie within the compulsory jurisdiction of the International Court of Justice [(ICJ)],” and allows parties to the Protocol to bring such disputes before the ICJ. Id., at 326. The United States gave notice of its withdrawal from the Optional Protocol on March 7, 2005. Letter from Condoleezza Rice, Secretary of State, to Kofi A. Annan, Secretary-General of the United Nations.

Petitioner Moises Sanchez-Llamas is a Mexican national. In December 1999, he was involved in an exchange of gunfire with police in which one officer suffered a gunshot wound in the leg. Police arrested Sanchez-Llamas and gave him warnings under Miranda v. Arizona, 384 U. S. 436 (1966), in
Shortly after the arrest and Miranda warnings, police interrogated Sanchez-Llamas with the assistance of an interpreter. In the course of the interrogation, Sanchez-Llamas made several incriminating statements regarding the shootout with police. He was charged with attempted aggravated murder, attempted murder, and several other offenses. Before trial, Sanchez-Llamas moved to suppress the statements he made to police. He argued that suppression was warranted because the statements were made involuntarily and because the authorities had failed to comply with Article 36 of the Vienna Convention. The trial court denied the motion. The case proceeded to trial, and Sanchez-Llamas was convicted and sentenced to 20½ years in prison.
He appealed, again arguing that the Vienna Convention violation required suppression of his statements. The Oregon Court of Appeals affirmed. Judgt. order reported at 191 Ore. App. 399, 84 P. 3d 1133 (2004). The Oregon Supreme Court also affirmed, concluding that Article 36 “does not create rights to consular access or notification that are enforceable by detained individuals in a judicial proceeding.” 338 Ore. 267, 276, 108 P. 3d 573, 578 (2005) (en banc). We granted certiorari. 546 U. S. 1001 (2005).

Petitioner Mario Bustillo, a Honduran national, was with several other men at a restaurant in Springfield, Virginia, on the night of December 10, 1997. That evening, outside the restaurant, James Merry was struck in the head with a baseball bat as he stood smoking a cigarette. He died several days later. Several witnesses at the scene identified Bustillo as the assailant. Police arrested Bustillo the morning after the attack and eventually charged him with mur-
At trial, the defense pursued a theory that another man, known as “Sirena,” was responsible for the attack. Two defense witnesses testified that Bustillo was not the killer. One of the witnesses specifically identified the attacker as Sirena. In addition, a third defense witness stated that she had seen Sirena on a flight to Honduras the day after the victim died. In its closing argument before the jury, the prosecution dismissed the defense theory about Sirena. See App. in No. 05-51, p. 21 (“This whole Sirena thing, I don‘t want to dwell on it too much. It‘s very convenient that Mr. Sirena apparently isn‘t available“). A jury convicted Bustillo of first-degree murder, and he was sentenced to 30 years in prison. His conviction and sentence were affirmed on appeal.
After his conviction became final, Bustillo filed a petition for a writ of habeas corpus in state court. There, for the first time, he argued that authorities had violated his right to consular notification under Article 36 of the Vienna Convention. He claimed that if he had been advised of his right to confer with the Honduran Consulate, he “would have done so without delay.” App. in No. 05-51, at 60. Moreover, the Honduran Consulate executed an affidavit stating that “it would have endeavoured to help Mr. Bustillo in his defense” had it learned of his detention prior to trial. Id., at 74. Bustillo insisted that the consulate could have helped him locate Sirena prior to trial. His habeas petition also argued, as part of a claim of ineffective assistance of counsel, that his attorney should have advised him of his right to notify the Honduran Consulate of his arrest and detention.2
The state habeas court dismissed Bustillo‘s Vienna Convention claim as “procedurally barred” because he had failed to raise the issue at trial or on appeal. App. to Pet. for Cert. in No. 05-51, p. 43a. The court also denied Bustillo‘s claim of ineffective assistance of counsel, ruling that his belated claim that counsel should have informed him of his Vienna Convention rights was barred by the applicable statute of limitations and also meritless under Strickland v. Washington, 466 U. S. 668 (1984). App. in No. 05-51, at 132. In an order refusing Bustillo‘s petition for appeal, the Supreme Court of Virginia found “no reversible error” in the habeas court‘s dismissal of the Vienna Convention claim. App. to Pet. for Cert. in No. 05-51, at 1a. We granted certiorari to consider the Vienna Convention issue. 546 U. S. 1001 (2005).
II
We granted certiorari as to three questions presented in these cases: (1) whether Article 36 of the Vienna Convention grants rights that may be invoked by individuals in a judicial proceeding; (2) whether suppression of evidence is a proper remedy for a violation of Article 36; and (3) whether an Article 36 claim may be deemed forfeited under state procedural rules because a defendant failed to raise the claim at trial.
As a predicate to their claims for relief, Sanchez-Llamas and Bustillo each argue that Article 36 grants them an individually enforceable right to request that their consular officers be notified of their detention, and an accompanying
A
Sanchez-Llamas argues that the trial court was required to suppress his statements to police because authorities never told him of his rights under Article 36. He refrains, however, from arguing that the Vienna Convention itself mandates suppression. We think this a wise concession. The Convention does not prescribe specific remedies for violations of Article 36. Rather, it expressly leaves the implementation of Article 36 to domestic law: Rights under Article 36 are to “be exercised in conformity with the laws and regulations of the receiving State.” Art. 36(2), 21 U. S. T., at 101. As far as the text of the Convention is concerned, the question of the availability of the exclusionary rule for Article 36 violations is a matter of domestic law.
It would be startling if the Convention were read to require suppression. The exclusionary rule as we know it is an entirely American legal creation. See Bivens v. Six Unknown Fed. Narcotics Agents, 403 U. S. 388, 415 (1971)
For good reason then, Sanchez-Llamas argues only that suppression is required because it is the appropriate remedy for an Article 36 violation under United States law, and urges us to require suppression for Article 36 violations as a matter of our “authority to develop remedies for the enforcement of federal law in state-court criminal proceedings.” Reply Brief for Petitioner in No. 04-10566, p. 11.
For their part, the State of Oregon and the United States, as amici curiae, contend that we lack any such authority over state-court proceedings. They argue that our cases suppressing evidence obtained in violation of federal statutes are grounded in our supervisory authority over the federal courts—an authority that does not extend to state-court proceedings. Brief for Respondent in No. 04-10566, pp. 42-43; Brief for United States 32-34; see McNabb v. United States, 318 U. S. 332, 341 (1943) (suppressing evidence for violation of federal statute requiring persons arrested without a warrant to be promptly presented to a judicial officer); Mallory v. United States, 354 U. S. 449 (1957) (suppressing evidence for violation of similar requirement of
To the extent Sanchez-Llamas argues that we should invoke our supervisory authority, the law is clear: “It is beyond dispute that we do not hold a supervisory power over the courts of the several States.” Dickerson v. United States, 530 U. S. 428, 438 (2000); see also Smith v. Phillips, 455 U. S. 209, 221 (1982) (“Federal courts hold no supervisory authority over state judicial proceedings and may intervene only to correct wrongs of constitutional dimension“). The cases on
We also agree with the State of Oregon and the United States that our authority to create a judicial remedy applicable in state court must lie, if anywhere, in the treaty itself. Under the Constitution, the President has the power, “by and with the Advice and Consent of the Senate, to make Treaties.”
Of course, it is well established that a self-executing treaty binds the States pursuant to the Supremacy Clause, and that the States therefore must recognize the force of the treaty in the course of adjudicating the rights of litigants. See, e. g., Hauenstein v. Lynham, 100 U. S. 483 (1880). And where a treaty provides for a particular judicial remedy,
Sanchez-Llamas argues that the language of the Convention implicitly requires a judicial remedy because it states that the laws and regulations governing the exercise of Article 36 rights “must enable full effect to be given to the purposes for which the rights . . . are intended,” Art. 36(2), 21 U. S. T., at 101 (emphasis added). In his view, although “full effect” may not automatically require an exclusionary rule, it does require an appropriate judicial remedy of some kind. There is reason to doubt this interpretation. In particular, there is little indication that other parties to the Convention have interpreted Article 36 to require a judicial remedy in the context of criminal prosecutions. See Department of State Answers to Questions Posed by the First Circuit in United States v. Nai Fook Li, No. 97-2034 etc., p. A-9 (Oct. 15, 1999) (“We are unaware of any country party to the [Vienna Convention] that provides remedies for violations of consular notification through its domestic criminal justice system“).
Nevertheless, even if Sanchez-Llamas is correct that Article 36 implicitly requires a judicial remedy, the Convention equally states that Article 36 rights “shall be exercised in conformity with the laws and regulations of the receiving State.” Art. 36(2), 21 U. S. T., at 101. Under our domestic law, the exclusionary rule is not a remedy we apply lightly. “[O]ur cases have repeatedly emphasized that the rule‘s ‘costly toll’ upon truth-seeking and law enforcement objectives presents a high obstacle for those urging application of the rule.” Pennsylvania Bd. of Probation and Parole v. Scott, 524 U. S. 357, 364-365 (1998). Because the rule‘s social costs are considerable, suppression is warranted only where the rule‘s “‘remedial objectives are thought most efficaciously served.‘” United States v. Leon, 468 U. S. 897, 908 (1984) (quoting United States v. Calandra, 414 U. S. 338, 348 (1974)).
We have applied the exclusionary rule primarily to deter constitutional violations. In particular, we have ruled that the Constitution requires the exclusion of evidence obtained by certain violations of the Fourth Amendment, see Taylor v. Alabama, 457 U. S. 687, 694 (1982) (arrests in violation of the Fourth Amendment); Mapp v. Ohio, 367 U. S. 643, 655-657 (1961) (unconstitutional searches and seizures), and confessions exacted by police in violation of the right against compelled self-incrimination or due process, see Dickerson, 530 U. S., at 435 (failure to give Miranda warnings); Payne v. Arkansas, 356 U. S. 560, 568 (1958) (involuntary confessions).
The few cases in which we have suppressed evidence for statutory violations do not help Sanchez-Llamas. In those cases, the excluded evidence arose directly out of statutory violations that implicated important Fourth and Fifth Amendment interests. McNabb, for example, involved the suppression of incriminating statements obtained during a prolonged detention of the defendants, in violation of a statute requiring persons arrested without a warrant to be promptly presented to a judicial officer. We noted that the statutory right was intended to “avoid all the evil implications of secret interrogation of persons accused of crime,” 318 U. S., at 344, and later stated that McNabb was “responsive to the same considerations of Fifth Amendment policy that . . . face[d] us . . . as to the States” in Miranda, 384 U. S., at 463. Similarly, in Miller, we required suppression of evidence that was the product of a search incident to an unlawful arrest. 357 U. S., at 305; see California v. Hodari D., 499 U. S. 621, 624 (1991) (“We have long understood that
The violation of the right to consular notification, in contrast, is at best remotely connected to the gathering of evidence. Article 36 has nothing whatsoever to do with searches or interrogations. Indeed, Article 36 does not guarantee defendants any assistance at all. The provision secures only a right of foreign nationals to have their consulate informed of their arrest or detention—not to have their consulate intervene, or to have law enforcement authorities cease their investigation pending any such notice or intervention. In most circumstances, there is likely to be little connection between an Article 36 violation and evidence or statements obtained by police.
Moreover, the reasons we often require suppression for Fourth and Fifth Amendment violations are entirely absent from the consular notification context. We require exclusion of coerced confessions both because we disapprove of such coercion and because such confessions tend to be unreliable. Watkins v. Sowders, 449 U. S. 341, 347 (1981). We exclude the fruits of unreasonable searches on the theory that without a strong deterrent, the constraints of the Fourth Amendment might be too easily disregarded by law enforcement. Elkins v. United States, 364 U. S. 206, 217 (1960). The situation here is quite different. The failure to inform a defendant of his Article 36 rights is unlikely, with any frequency, to produce unreliable confessions. And unlike the search-and-seizure context—where the need to obtain valuable evidence may tempt authorities to transgress Fourth Amendment limitations—police win little, if any, practical advantage from violating Article 36. Suppression would be a vastly disproportionate remedy for an Article 36 violation.
Sanchez-Llamas counters that the failure to inform defendants of their right to consular notification gives them
Leaving aside the suggestion that it is the role of police generally to advise defendants of their legal options, we think other constitutional and statutory requirements effectively protect the interests served, in Sanchez-Llamas’ view, by Article 36. A foreign national detained on suspicion of crime, like anyone else in our country, enjoys under our system the protections of the Due Process Clause. Among other things, he is entitled to an attorney, and is protected against compelled self-incrimination. See Wong Wing v. United States, 163 U. S. 228, 238 (1896) (“[A]ll persons within the territory of the United States are entitled to the protection guaranteed by” the Fifth and Sixth Amendments). Article 36 adds little to these “legal options,” and we think it unnecessary to apply the exclusionary rule where other constitutional and statutory protections—many of them already enforced by the exclusionary rule—safeguard the same interests Sanchez-Llamas claims are advanced by Article 36.
Finally, suppression is not the only means of vindicating Vienna Convention rights. A defendant can raise an Article 36 claim as part of a broader challenge to the voluntariness of his statements to police. If he raises an Article 36 violation at trial, a court can make appropriate accommodations to ensure that the defendant secures, to the extent possible, the benefits of consular assistance. Of course, diplomatic avenues—the primary means of enforcing the Convention—also remain open.
In sum, neither the Vienna Convention itself nor our precedents applying the exclusionary rule support suppression of Sanchez-Llamas’ statements to police.

The Virginia courts denied petitioner Bustillo‘s Article 36 claim on the ground that he failed to raise it at trial or on direct appeal. The general rule in federal habeas cases is
that a defendant who fails to raise a claim on direct appeal is barred from raising the claim on collateral review. See Massaro v. United States, 538 U. S. 500, 504 (2003); Bousley v. United States, 523 U. S. 614, 621 (1998). There is an exception if a defendant can demonstrate both “cause” for not raising the claim at trial, and “prejudice” from not having done so. Massaro, supra, at 504. Like many States, Virginia applies a similar rule in state postconviction proceedings, and did so here to bar Bustillo‘s Vienna Convention claim. Normally, in our review of state-court judgments, such rules constitute an adequate and independent state-law ground preventing us from reviewing the federal claim. Coleman v. Thompson, 501 U. S. 722, 729 (1991). Bustillo contends, however, that state procedural default rules cannot apply to Article 36 claims. He argues that the Convention requires that Article 36 rights be given “full effect” and that Virginia‘s procedural default rules “prevented any effect (much less ‘full effect‘) from being given to” those rights. Brief for Petitioner in No. 05-51, p. 35 (emphasis deleted).
This is not the first time we have been asked to set aside procedural default rules for a Vienna Convention claim. Respondent Johnson and the United States persuasively argue that this question is controlled by our decision in Breard v. Greene, 523 U. S. 371 (1998) (per curiam). In Breard, the petitioner failed to raise an Article 36 claim in state court—at trial or on collateral review—and then sought to have the claim heard in a subsequent federal habeas proceeding. Id., at 375. He argued that “the Convention is the ‘supreme law of the land’ and thus trumps the procedural default doctrine.” Ibid. We rejected this argument as “plainly incorrect,” for two reasons. Ibid. First, we observed, “it has been recognized in international law that, absent a clear and express statement to the contrary, the procedural rules of the forum State govern the implementation of the treaty in that State.” Ibid. Furthermore, we reasoned that while treaty protections such as Article 36 may constitute supreme federal law, this is “no less true of provisions of the Constitu-
Bustillo offers two reasons why Breard does not control his case. He first argues that Breard‘s holding concerning procedural default was “unnecessary to the result,” Brief for Petitioner in No. 05-51, at 45, because the petitioner there could not demonstrate prejudice from the default and because, in any event, a subsequent federal statute—the Antiterrorism and Effective Death Penalty Act of 1996, 110 Stat. 1214—superseded any right the petitioner had under the Vienna Convention to have his claim heard on collateral review. We find Bustillo‘s contention unpersuasive. Our resolution of the procedural default question in Breard was the principal reason for the denial of the petitioner‘s claim, and the discussion of the issue occupied the bulk of our reasoning. See 523 U. S., at 375-377. It is no answer to argue, as Bustillo does, that the holding in Breard was “unnecessary” simply because the petitioner in that case had several ways to lose. See Richmond Screw Anchor Co. v. United States, 275 U. S. 331, 340 (1928).
Bustillo‘s second reason is less easily dismissed. He argues that since Breard, the ICJ has interpreted the Vienna Convention to preclude the application of procedural default rules to Article 36 claims. The LaGrand Case (F. R. G. v. U. S.), 2001 I. C. J. 466 (Judgment of June 27) (LaGrand), and the Case Concerning Avena and other Mexican Nationals (Mex. v. U. S.), 2004 I. C. J. 12 (Judgment of Mar. 31) (Avena), were brought before the ICJ by the governments of Germany and Mexico, respectively, on behalf of several of their nationals facing death sentences in the United States. The foreign governments claimed that their nationals had not been informed of their right to consular notification. They further argued that application of the procedural default rule to their nationals’ Vienna Convention claims failed
Bustillo argues that LaGrand and Avena warrant revisiting the procedural default holding of Breard. In a similar vein, several amici contend that “the United States is obligated to comply with the Convention, as interpreted by the ICJ.” Brief for ICJ Experts 11 (emphasis added). We disagree. Although the ICJ‘s interpretation deserves “respectful consideration,” Breard, supra, at 375, we conclude that it does not compel us to reconsider our understanding of the Convention in Breard.4
Under our
Nothing in the structure or purpose of the ICJ suggests that its interpretations were intended to be conclusive on our courts.5 The ICJ‘s decisions have “no binding force except between the parties and in respect of that particular case,” Statute of the International Court of Justice, Art. 59, 59 Stat. 1062, T. S. No. 993 (1945) (emphasis added). Any interpretation of law the ICJ renders in the course of resolving particu-
In addition, “[w]hile courts interpret treaties for themselves, the meaning given them by the departments of government particularly charged with their negotiation and enforcement is given great weight.” Kolovrat v. Oregon, 366 U. S. 187, 194 (1961). Although the United States has agreed to “discharge its international obligations” in having state courts give effect to the decision in Avena, it has not taken the view that the ICJ‘s interpretation of Article 36 is binding on our courts. President Bush, Memorandum for the Attorney General (Feb. 28, 2005), App. to Brief for United States as Amicus Curiae in Medellín v. Dretke, O. T. 2004, No. 04-5928, p. 9a. Moreover, shortly after Avena, the United States withdrew from the Optional Protocol concerning Vienna Convention disputes. Whatever the effect of Avena and LaGrand before this withdrawal, it is doubtful that our courts should give decisive weight to the interpretation of a tribunal whose jurisdiction in this area is no longer recognized by the United States.
LaGrand and Avena are therefore entitled only to the “respectful consideration” due an interpretation of an international agreement by an international court. Breard, 523 U. S., at 375. Even according such consideration, the ICJ‘s interpretation cannot overcome the plain import of Article 36. As we explained in Breard, the procedural rules of domestic law generally govern the implementation of an international treaty. Ibid. In addition, Article 36 makes clear that the rights it provides “shall be exercised in conformity with the laws and regulations of the receiving State” provided that “full effect ... be given to the purposes for which the rights accorded under this Article are intended.” Art. 36(2), 21 U. S. T., at 101. In the United States, this means that the rule of procedural default—which applies even to claimed violations of our
The ICJ concluded that where a defendant was not notified of his rights under Article 36, application of the procedural default rule failed to give “full effect” to the purposes of Article 36 because it prevented courts from attaching “legal significance” to the Article 36 violation. LaGrand, 2001 I. C. J., at 497-498, ¶¶ 90-91. This reasoning overlooks the importance of procedural default rules in an adversary system, which relies chiefly on the parties to raise significant issues and present them to the courts in the appropriate manner at the appropriate time for adjudication. See Castro v. United States, 540 U. S. 375, 386 (2003) (SCALIA, J., concurring in part and concurring in judgment) (“Our adversary system is designed around the premise that the parties know what is best for them, and are responsible for advancing the facts and arguments entitling them to relief“). Procedural default rules are designed to encourage parties to raise their claims promptly and to vindicate “the law‘s important interest in the finality of judgments.” Massaro, 538 U. S., at 504. The consequence of failing to raise a claim for adjudication at the proper time is generally forfeiture of that
Procedural default rules generally take on greater importance in an adversary system such as ours than in the sort of magistrate-directed, inquisitorial legal system characteristic of many of the other countries that are signatories to the Vienna Convention. “What makes a system adversarial rather than inquisitorial is ... the presence of a judge who does not (as an inquisitor does) conduct the factual and legal investigation himself, but instead decides on the basis of facts and arguments pro and con adduced by the parties.” McNeil v. Wisconsin, 501 U. S. 171, 181, n. 2 (1991). In an inquisitorial system, the failure to raise a legal error can in part be attributed to the magistrate, and thus to the state itself. In our system, however, the responsibility for failing to raise an issue generally rests with the parties themselves.
The ICJ‘s interpretation of Article 36 is inconsistent with the basic framework of an adversary system. Under the ICJ‘s reading of “full effect,” Article 36 claims could trump not only procedural default rules, but any number of other rules requiring parties to present their legal claims at the appropriate time for adjudication. If the state‘s failure to inform the defendant of his Article 36 rights generally excuses the defendant‘s failure to comply with relevant procedural rules, then presumably rules such as statutes of limitations and prohibitions against filing successive habeas petitions must also yield in the face of Article 36 claims. This sweeps too broadly, for it reads the “full effect” proviso in a way that leaves little room for Article 36‘s clear instruction that Article 36 rights “shall be exercised in conformity with the laws and regulations of the receiving State.” Art. 36(2), 21 U. S. T., at 101.6
Much as Sanchez-Llamas cannot show that suppression is an appropriate remedy for Article 36 violations under domestic law principles, so too Bustillo cannot show that normally applicable procedural default rules should be suspended in light of the type of right he claims. In this regard, a comparison of Article 36 and a suspect‘s rights under Miranda disposes of Bustillo‘s claim. Bustillo contends that applying procedural default rules to Article 36 rights denies such rights “full effect” because the violation itself—i. e., the failure to inform defendants of their right to
To the extent the dissent suggests that the ICJ‘s decisions could be read to prevent application of procedural default rules where a defendant‘s attorney is unaware of Article 36, see post, at 387-388 (opinion of BREYER, J.), this interpretation of the Convention is in sharp conflict with the role of counsel in our system. “Attorney ignorance or inadvertence is not ‘cause’ because the attorney is the petitioner‘s agent when acting, or failing to act, in furtherance of the litigation, and the petitioner must ‘bear the risk of attorney error.‘” Coleman v. Thompson, 501 U. S. 722, 753 (1991) (quoting Murray v. Carrier, 477 U. S. 478, 488 (1986)). Under our system, an attorney‘s lack of knowledge does not excuse the defendant‘s default, unless the attorney‘s overall representation falls below what is required by the
Bustillo responds that an Article 36 claim more closely resembles a claim, under Brady v. Maryland, 373 U. S. 83 (1963), that the prosecution failed to disclose exculpatory evidence—a type of claim that often can be asserted for the first time only in postconviction proceedings. See United States v. Dominguez Benitez, 542 U. S. 74, 83, n. 9 (2004). The analogy is inapt. In the case of a Brady claim, it is impossible for the defendant to know as a factual matter that a violation has occurred before the exculpatory evidence is disclosed. By contrast, a defendant is well aware of the fact that he was not informed of his Article 36 rights, even if the legal significance of that fact eludes him.
Finally, relying on Massaro v. United States, 538 U. S. 500 (2003), Bustillo argues that Article 36 claims “are most appropriately raised post-trial or on collateral review.” Brief for Petitioner in No. 05-51, at 39. Massaro held that claims of ineffective assistance of counsel may be raised for the first time in a proceeding under
We therefore conclude, as we did in Breard, that claims under Article 36 of the Vienna Convention may be subjected to the same procedural default rules that apply generally to other federal-law claims.

Although these cases involve the delicate question of the application of an international treaty, the issues in many ways turn on established principles of domestic law. Our holding in no way disparages the importance of the Vienna Convention. The relief petitioners request is, by any measure, extraordinary. Sanchez-Llamas seeks a suppression remedy for an asserted right with little if any connection to the gathering of evidence; Bustillo requests an exception to procedural rules that is accorded to almost no other right, including many of our most fundamental constitutional protections. It is no slight to the Convention to deny petitioners’ claims under the same principles we would apply to an Act of Congress, or to the
The judgments of the Supreme Court of Oregon and the Supreme Court of Virginia are affirmed.
It is so ordered.
JUSTICE GINSBURG, concurring in the judgment.
I agree that Article 36 of the Vienna Convention grants rights that may be invoked by an individual in a judicial proceeding, and therefore join Part II of JUSTICE BREYER‘S dissenting opinion. As to the suppression and procedural default issues, I join the Court‘s judgment. The dissenting opinion veers away from the two cases here for review, imagining other situations unlike those at hand. In neither of the cases before us would I remand for further proceedings.
I turn first to the question whether a violation of Article 36 requires suppression of statements to police officers in Sanchez-Llamas’ case and others like it. Shortly after his arrest and in advance of any police interrogation, Sanchez-Llamas received the warnings required by Miranda v. Arizona, 384 U. S. 436 (1966), in both English and Spanish. Tr. 122 (Nov. 16, 2000). He indicated that he understood those warnings, id., at 123, telling the police that he had lived in the United States for approximately 11 years, id., at 124, 143, 177. After a break in questioning, Sanchez-Llamas again received Miranda warnings in Spanish, and again indicated that he understood them. Tr. 129, 176. Sanchez-Llamas, with his life experience in the United States, scarcely resembles the uncomprehending detainee imagined by JUSTICE BREYER, post, at 393. Such a detainee would have little need to invoke the Vienna Convention, for Miranda warnings a defendant is unable to comprehend give the police no green light for interrogation. Moran v. Burbine, 475 U. S. 412, 421 (1986) (a defendant‘s waiver of Miranda rights must be voluntary, knowing, and intelligent, i. e., “the product of a free and deliberate choice ... made with a full awareness of both the nature of the right being abandoned and the consequences of the decision to abandon it“); United States v. Garibay, 143 F. 3d 534, 537-540 (CA9 1998) (defendant, who had difficulty understanding English, did not knowingly and intelligently waive his Miranda rights where the police recited the Miranda warnings only in English); United States v. Short, 790 F. 2d 464, 469 (CA6 1986) (defendant‘s limited comprehension of English cast substantial doubt on the validity of her Miranda waiver).1
As to the procedural default issue, I note first two anomalies. The Court explains, and I agree, that it would be extraordinary to hold that defendants, unaware of their Miranda rights because the police failed to convey the required warnings, would be subject to a State‘s procedural default rules, but defendants not told of Article 36 rights would face no such hindrance. See ante, at 359. Furthermore, as the dissent apparently recognizes, in the federal-court system, a later-in-time statute, codifying a federal procedural default rule, would “supersed[e] any inconsistent provision in the Convention.” Post, at 388 (citing Breard v. Greene, 523 U. S. 371 (1998) (per curiam)). In my view, it would be unseemly, to say the least, for this Court to command state courts to relax their identical, or even less stringent procedural default rules, while federal courts operate without constraint in this regard. Post, at 388-389. That state of affairs, surely productive of friction in our federal system, should be resisted if there is a plausible choice, i. e., if a reasonable interpretation of the federal statute and international accord would avoid the conflict.
Critical for me, Bustillo has conceded that his “attorney at trial was aware of his client‘s rights under the Vienna
In short, if there are some times when a Convention violation, standing alone, might warrant suppression, or the displacement of a State‘s ordinarily applicable procedural

For the reasons stated, I would not disturb the judgments of the Supreme Court of Oregon and the Supreme Court of Virginia.
JUSTICE BREYER, with whom JUSTICE STEVENS and JUSTICE SOUTER join, and with whom JUSTICE GINSBURG joins as to Part II, dissenting.
The Vienna Convention on Consular Relations (Vienna Convention or Convention) provides that when the police of a signatory nation arrest a foreign national, the detaining “authorities shall inform” the foreign national “without delay” of his “righ[t]” to communicate with his nation‘s consular officers. Arts. 36(1)(a), (b), Apr. 24, 1963, [1970] 21 U. S. T. 77, 100-101, T. I. A. S. No. 6820. We granted certiorari in these cases to consider three related questions: (1) May a criminal defendant raise a claim (at trial or in a postconviction proceeding) that state officials violated this provision? (2) May a State apply its usual procedural default rules to Convention claims, thereby denying the defendant the right to raise the claim in a postconviction proceeding on the ground that the defendant failed to raise the claim at trial? And (3) is suppression of a defendant‘s confession (made to police after a violation of the Convention) an appropriate remedy?
The Court assumes, but does not decide, that the answer to the first question is “yes.” Ante, at 343. It answers the second question by holding that a State always may apply its ordinary procedural default rules to a defendant‘s claim of a Convention violation. Ante, at 350-360. Its answer to the third question is that suppression is never an appropriate remedy for a Convention violation. Ante, at 343-350.
Unlike the majority, I would decide the first question and answer it affirmatively. A criminal defendant may, at trial or in a postconviction proceeding, raise the claim that state authorities violated the Convention in his case. My answer to the second question is that sometimes state procedural default rules must yield to the Convention‘s insistence that domestic laws “enable full effect to be given to the purposes for which” Article 36‘s “rights ... are intended.” Art. 36(2), 21 U. S. T., at 101. And my answer to the third question is that suppression may sometimes provide an appropriate remedy. After answering these questions, I would remand these cases, thereby permitting the States to apply their own procedural and remedial laws, but with the understanding that the

A
The Vienna Convention is an international treaty that governs relations between individual nations and foreign consular officials. The United States and 169 other nations have ratified the Convention. Its adoption in 1963 was perhaps “the single most important event in the entire history of the consular institution.” L. Lee, Consular Law and Practice 26 (2d ed. 1991). The Convention defines consular functions to include “protecting in the receiving State the interests of the sending State and of its nationals,” and “helping and assisting nationals ... of the sending State.” Arts. 5(a), (e), 21 U. S. T., at 82-83. The United States ratified the Convention in 1969.
Article 36 of the Convention governs relations between a consulate and its nationals, particularly those who have been arrested by the host country. Its object is to assure consular communication and assistance to such nationals, who may not fully understand the host country‘s legal regime or even speak its language. Article 36 reads as follows:
“1. With a view to facilitating the exercise of consular functions relating to nationals of the sending State:
“(a) consular officers shall be free to communicate with nationals of the sending State and to have access to them. Nationals of the sending State shall have the same freedom with respect to communication with and access to consular officers of the sending State;
“(b) if he so requests, the competent authorities of the receiving State shall, without delay, inform the consular post of the sending State if, within its consular district, a national of that State is arrested or committed to prison or to custody pending trial or is detained in any other manner. Any communication addressed to the consular post by the person arrested, in prison, custody or detention shall also be forwarded by the said authorities without delay. The said authorities shall inform the person concerned without delay of his rights under this sub-paragraph;
“2. The rights referred to in paragraph 1 of this Article shall be exercised in conformity with the laws and regulations of the receiving State, subject to the proviso, however, that the said laws and regulations must enable full effect to be given to the purposes for which the rights accorded under this Article are intended.” 21 U. S. T., at 100-101 (emphasis added).
The U. S. State Department‘s Foreign Affairs Manual has long stressed the importance the United States places upon these provisions. It says, “[O]ne of the basic functions of a
B
In 1969, the United States also ratified (but the President has since withdrawn from) an Optional Protocol to the Convention. See Optional Protocol Concerning the Compulsory Settlement of Disputes (Optional Protocol), Apr. 24, 1963, [1970] 21 U. S. T. 325, T. I. A. S. No. 6820; Letter from Condoleezza Rice, Secretary of State, to Kofi A. Annan, Secretary-General of the United Nations (Mar. 7, 2005) (giving notice of United States’ withdrawal from the Optional Protocol). The Optional Protocol provides that “[d]isputes arising out of the interpretation or application of the Convention shall lie within the compulsory jurisdiction of the International Court of Justice [ICJ].” Art. I, 21 U. S. T., at 326.
Acting pursuant to the Optional Protocol, Germany (in 1999) and Mexico (in 2003) brought proceedings before the ICJ, seeking redress for what they said were violations of Article 36 by the United States. LaGrand Case (F. R. G. v. U. S.), 2001 I. C. J. 466 (Judgment of June 27) (LaGrand); Case Concerning Avena and other Mexican Nationals (Mex. v. U. S.), 2004 I. C. J. 12 (Judgment of Mar. 31) (Avena).
In Germany‘s case, the ICJ rejected the United States’ claim that the “rights of consular notification and access under [Article 36] are rights of States, and not of individuals.” LaGrand, 2001 I. C. J., at 493, ¶ 76. It held instead that (1) if an arrested foreign national is prejudiced by the host country‘s failure to inform him of his Article 36 rights, and (2) if that individual has “been subjected to prolonged detention or convicted and sentenced to severe penalties,” then a diplomatic apology alone is not a sufficient remedy.
In Mexico‘s case, the ICJ reiterated its view that Article 36, in addition to imposing obligations on member nations, also allows foreign nationals to bring claims based on those violations in domestic judicial proceedings. The ICJ noted that, as a matter of international law, breach of a treaty ordinarily “involves an obligation to make reparation in an adequate form.” Avena, supra, at 59, ¶ 119 (quoting Factory at Chorzów, Jurisdiction, 1927, P. C. I. J., ser. A, No. 9, p. 21). Applying that principle to the Convention, the ICJ concluded that “the remedy to make good ... violations [of Article 36] should consist in an obligation on the United States to permit review and reconsideration of these nationals’ cases by the United States courts ... with a view to ascertaining whether in each case the violation ... caused actual prejudice to the defendant in the process of administration of criminal justice.” Avena, 2004 I. C. J., at 60, ¶ 121 (emphasis added). The court added that this “‘review and reconsideration,‘” to
In respect to procedural default, the ICJ referenced what it said in LaGrand, while adding the critically important qualification that the cases in which the Convention blocked application of a procedural default rule were those in which it was “the failure of the United States itself to inform” an arrested foreign national of his right to contact the consulate that “precluded counsel from being in a position to have raised the question of a violation of the Vienna Convention in the initial trial.” Avena, supra, at 57, ¶ 113.
C
For present purposes, the key sections of the Convention are (1) the provision that requires the United States to “inform” an arrested person “without delay” of his Article 36 rights, including the right to “communicat[e]” with his “consular post,” and (2) the provision that says domestic laws and regulations “must enable full effect to be given” to the purposes underlying those requirements.
The key ICJ holdings are its determinations (1) that the Convention obligates a member nation to inform an arrested foreign national without delay that he may contact his consulate; (2) that the Convention requires the United States to provide some process for its courts to “review and reconside[r]” criminal convictions where there has been a prejudicial violation of this obligation; and (3) that this “review and reconsideration” cannot be foreclosed on the ground that the foreign national did not raise the violation at trial where the
II
The first question presented is whether a criminal defendant may raise a claim (at trial or in a postconviction proceeding) that state officials violated Article 36 of the Convention. The Court assumes that the answer to this question is “yes,” but it does not decide the matter because it concludes in any event that the petitioners are not entitled to the remedies they seek. As explained below, I would resolve those remedial questions differently. Hence, I must decide, rather than assume, the answer to the first question presented.
Regardless, the first question raises an important issue of federal law that has arisen hundreds of times in the lower federal and state courts. See generally
Bustillo, for example, has brought an action under a Virginia statute that allows any convicted person to seek release from custody on the ground that “he is detained without lawful authority.”
The petitioners must be right in respect to their claim that the Convention provides law that here courts could apply in their respective proceedings. The Convention is a treaty. And “all Treaties made ... under the Authority of the United States, shall be the supreme Law of the Land; and the Judges in every State shall be bound thereby.” Ibid. As
Directly to the point, this Court stated long ago that a treaty “is a law of the land as an act of Congress is, whenever its provisions prescribe a rule by which the rights of the private citizen or subject may be determined. And when such rights are of a nature to be enforced in a court of justice,” in such a case the court is to “resor[t] to the treaty for a rule of decision for the case before it as it would to a statute.” Head Money Cases, 112 U. S. 580, 598-599 (1884).
As noted above, see supra, at 372, the parties agree that the Convention “operates of itself without the aid of any legislative provision.” Foster, supra, at 314. The question, then, is the one this Court set forth in the Head Money Cases: Does the Convention set forth a “law” with the legal stature of an Act of Congress? And as the Court explained, we are to answer that question by asking, does the Convention “prescribe a rule by which the rights of the private citizen ... may be determined“? Are the obligations set forth in Article 36(1)(b) “of a nature to be enforced in a court of justice“?
The “nature” of the Convention provisions raised by the petitioners indicates that they are intended to set forth standards that are judicially enforceable. Those provisions consist of the rights of a foreign national “arrested” or “detained in any other manner” (1) to have, on his “re-ques[t],” the “consular post” “inform[ed]” of that arrest or detention; (2) to have forwarded “without delay” any “communication addressed to the consular post“; and (3) to be “inform[ed] without delay” of those two “rights.” Art. 36(1)(b), 21 U. S. T., at 101. These rights do not differ in their “nature” from other procedural rights that courts commonly enforce. Cf.
Moreover, the language of Article 36 speaks directly of the “rights” of the individual foreign national. See Art. 36(1)(b), 21 U. S. T., at 101 (“The said authorities shall inform the person concerned without delay of his rights under this subparagraph” (emphasis added)). Article 36 thus stands in stark contrast to other provisions of the Convention, which speak in terms of the rights of the member nations or consular officials. Cf. Art. 9, id., at 86 (discussing “the right of any of the Contracting Parties to fix the designation of consular officers” (emphasis added)); Art. 34, id., at 98 (consular officials shall have “freedom of movement and travel“); Art. 35(1), id., at 99 (consular officials shall have “freedom of communication“); Art. 41(1), id., at 103 (“Consular officials shall not be liable to arrest or detention pending trial“).
Suppose that a pre-Miranda federal statute had said that arresting authorities “shall inform a detained person without delay of his right to counsel.” Would courts not have automatically assumed that this statute created applicable law that a criminal defendant could invoke at trial? What more would the statute have to say? See Medellín, 544 U. S., at 687 (O‘CONNOR, J., dissenting) (“And if a statute were to provide, for example, that arresting authorities ‘shall inform a detained person without delay of his right to counsel,’ what ‘more would be required’ to permit ‘a defendant’ to ‘invoke that statute‘?“).
Further, this Court has routinely permitted individuals to enforce treaty provisions similar to Article 36 in domestic judicial proceedings. In United States v. Rauscher, 119 U. S. 407, 410-411 (1886), for example, this Court concluded that the defendant could raise as a defense in his federal criminal trial the violation of an extradition treaty that said:
In all these cases, the Court recognized that (1) a treaty obligated the United States to treat foreign nationals in a certain manner; (2) the obligation had been breached by the Government‘s conduct; and (3) the foreign national could therefore seek redress for that breach in a judicial proceeding, even though the treaty did not specifically mention judicial enforcement of its guarantees or even expressly state that its provisions were intended to confer rights on the foreign national. Language and context argue yet more strongly here in favor of permitting a criminal defendant in an appropriate case to find in the Convention a law to apply in the proceeding against him.
In addition, the Government concedes that individual consular officials may enforce other provisions of the Convention in American courts. For example, Article 43(1) grants consular officials immunity from “the jurisdiction of the” host country‘s “judicial or administrative authorities” for
Finally, the international tribunal that the United States agreed would resolve disputes about the interpretation of the Convention, the ICJ, has twice ruled that an arrested foreign national may raise a violation of the arresting authorities’ obligation to “inform [him] without delay of his rights under” Article 36(1) in an American judicial proceeding. See Avena, 2004 I. C. J. 12; LaGrand, 2001 I. C. J. 466. That conclusion, as an “interpretation of an international agreement by an international court” deserves our “‘respectful consideration.‘” Ante, at 355 (opinion of the Court). That “respectful consideration,” for reasons I shall explain, see infra, at 382-385, counsels in favor of an interpretation that is consistent with the ICJ‘s reading of the Convention here.
The Government says to the contrary that Article 36 is “addressed solely to the rights of States and not private individuals“; hence, a foreign national may not claim in an American court that a State has convicted him without the consular notification that Article 36 requires. Brief for United States as Amicus Curiae 7. But its arguments are not persuasive. The Government rests this conclusion primarily upon its claim that there is a “long-established presumption that treaties and other international agreements do not create judicially enforceable individual rights.” Id., at 11.
The problem with that argument is that no such presumption exists. The Government cites three cases in support of
Regardless, as I have just said, see supra, at 373, the Head Money Cases make clear that a treaty may confer certain enforceable “rights upon the citizens or subjects of one of the nations residing in the territorial limits of the other.” 112 U. S., at 598; see also 2 Restatement (Third) on Foreign Relations Law of the United States § 907 (1986) (hereinafter Restatement) (“A private person having rights against the United States under an international agreement may assert those rights in courts in the United States“). And the language of the Convention makes clear that it is such a treaty. Indeed, to my knowledge no other nation‘s courts (or perhaps no more than one) have held to the contrary. The cases cited by the respondents and the Government do not say otherwise. See Judgment of Nov. 7, 2001, 5 BGHSt 116 (Germany) (deciding in light of LaGrand that the Convention creates individual rights, but declining to suppress confession); Queen v. Abbrederis (1981) 51 F. L. R. 99, 115 (Ct. Crim. App. New South Wales (Australia)) (deciding that Convention does not “affect the carrying out of an investigation by interrogation of a foreign person coming to this country“).
The Government also points out that the Executive Branch‘s interpretation of treaty provisions is entitled to “great weight.” Sumitomo Shoji America, Inc. v. Avagliano, 457 U. S. 176, 184, 185 (1982). I agree with this presumption. But the Executive‘s views on our treaty obligations are “not conclusive.” Id., at 184; see Perkins v. Elg, 307 U. S. 325, 328, 337-342 (1939) (declining to adopt Executive‘s treaty interpretation); Johnson v. Browne, 205 U. S. 309, 319-321 (1907) (same); De Lima v. Bidwell, 182 U. S. 1, 181, 194-199 (1901) (same). Where language, the nature of the right, and the ICJ‘s interpretation of the treaty taken separately or together so strongly point to an intent to confer enforceable rights upon an individual, I cannot find in the simple fact of the Executive Branch‘s contrary view sufficient reason to adopt the Government‘s interpretation of the Convention.
Accordingly, I would allow the petitioners to raise their claims based on violations of the Convention in their respective state-court proceedings.
III
The more difficult issue, I believe, concerns the nature of the Convention‘s requirements as to remedy. In particular, Bustillo‘s case concerns a state procedural default rule. When, if ever, does the Convention require a state court to set aside such a rule in order to hear a criminal defendant‘s
In my view, Article 36 of the Convention requires a less absolute answer. Article 36 says that the rights it sets forth “shall be exercised in conformity with the laws and regulations of the receiving State,” but it instantly adds, “subject to the proviso ... that the said laws and regulations must enable full effect to be given to the purposes for which the [Article 36] rights are ... intended.” Art. 36(2), 21 U. S. T., at 101 (emphasis added). The proviso means that a State‘s ordinary procedural default rules apply unless (1) the defendant‘s failure to raise a Convention matter (e. g., that police failed to inform him of his Article 36 rights) can itself be traced to the failure of the police (or other governmental authorities) to inform the defendant of those Convention rights, and (2) state law does not provide any other effective way for the defendant to raise that issue (say, through a claim of ineffective assistance of counsel).
Several considerations lead to this conclusion. First, as I have just noted, Article 36 says both that its rights “shall be exercised in conformity with” the host country‘s “laws and regulations” and that those “laws and regulations must enable full effect to be given” to the purposes for which those rights “are intended.” This interpretation makes both the “conformity” requirement and the “full effect” requirement meaningful.
Second, the Convention‘s drafting history supports this interpretation. The first draft of the Vienna Convention was written by the International Law Commission. Article 36(2) of that draft required only that domestic laws “not nullify” the rights afforded by the Convention. Draft Articles
Based on this objection, the Soviet Union proposed reverting to the original language. The United Kingdom opposed that measure, explaining that it supported the “full effect” version because the initial (“not nullify“) version
“meant that the laws and regulations of the receiving State would govern the rights specified ... provided that they did not render those rights completely inoperative—for ‘to nullify’ meant to ‘render completely inoperative‘. But rights could be seriously impaired without becoming completely inoperative. ... Consular officials should, of course, comply with the laws and regulations of the receiving State in such matters as the times for visiting prisoners, but it was most important that the substance of the rights and obligations specified ... should be preserved.” Id., ¶¶ 6-7, at 40.
Third, the decisions of the ICJ, fairly read, interpret the Convention similarly. In LaGrand and Avena, the ICJ read the Convention as authorizing an individual foreign national to raise an Article 36 violation at trial or in a postconviction proceeding. See Avena, 2004 I. C. J., at 59-60, ¶ 121; LaGrand, 2001 I. C. J., at 513-514, ¶ 125. The ICJ added that the Convention requires member states to provide “effective” remedies in their courts for Convention violations. See Avena, supra, at 65, ¶ 138. And the ICJ made two critical statements in respect to procedural default rules. In LaGrand, the court said that in “itself, the [procedural default] rule does not violate Article 36 of the Vienna Convention.” 2001 I. C. J., at 497, ¶ 90 (emphasis added). Rather, the “problem arises when the procedural default rule does not allow the detained individual to challenge a conviction and sentence by claiming ... that the competent national authorities failed to comply with their obligation to provide the requisite consular information ‘without delay.‘” Ibid. And the ICJ later specified that the Convention forbids American States to apply a procedural default rule to bar assertion of a Convention violation claim “where it has been the failure of the United States [or of a State] itself to inform that may have precluded counsel from being in a position to have raised the question of a violation of the Vienna Convention in the initial trial.” Avena, 2004 I. C. J., at 57, ¶ 113 (emphasis added).
I will assume that the ICJ‘s interpretation does not bind this Court in this case. Statute of the International Court of Justice, Art. 59, 59 Stat. 1062, T. S. No. 993 (1945) (ICJ decisions have “binding force” only “between the parties and in respect of that particular case“). But as the majority points out, the ICJ‘s decisions on this issue nonetheless warrant our “respectful consideration.” Ante, at 355. That
That “respectful consideration” also reflects an understanding of the ICJ‘s expertise in matters of treaty interpretation, a branch of international law. The ICJ‘s opinions “are persuasive evidence” of what “[international] law is.” 1 Restatement § 103, at 37, Comment b; see also Morrison, Treaties as a Source of Jurisdiction, Especially in U. S. Practice, in The International Court of Justice at a Crossroads 58, 61 (L. Damrosch ed. 1987); The Paquete Habana, 175 U. S. 677, 700 (1900) (“[T]rustworthy evidence of what [international] law really is” can be found in “the works of jurists and commentators, who by years of labor, research and experience, have made themselves peculiarly well acquainted with the subjects of which they treat“); L. Henkin, R. Pugh, O. Schachter, & H. Smit, International Law: Cases and Materials 120 (3d ed. 1993) (“[T]he decisions of the [ICJ] are, on
Thus, this Court has repeatedly looked to the ICJ for guidance in interpreting treaties and in other matters of international law. See, e. g., United States v. Maine, 475 U. S. 89, 99-100 (1986) (referring to the Fisheries Case (United Kingdom v. Norway), 1951 I. C. J. 116 (Judgment of Dec. 18), as legal authority in a maritime boundary dispute); United States v. Louisiana, 470 U. S. 93, 107 (1985) (same); United States v. Louisiana, 394 U. S. 11, 69-72 (1969) (same); First Nat. City Bank v. Banco Para el Comercio Exterior de Cuba, 462 U. S. 611, 628-629, and n. 20 (1983) (citing Case Concerning The Barcelona Traction, Light & Power Co., 1970 I. C. J. 3 (Judgment of Feb. 5), for the proposition that an incorporated entity “is not to be regarded as legally separate from its owners in all circumstances“); United States v. California, 381 U. S. 139, 172 (1965) (citing the Corfu Channel Case, 1949 I. C. J. Rep. 4 (Judgment of Apr. 9), in boundary dispute); Reid v. Covert, 354 U. S. 1, 61 (1957) (Frankfurter, J., concurring in result) (citing France v. United States, 1952 I. C. J.

The Court supports its interpretation in three basic ways. First, the majority says that “respectful consideration” does not require us to agree with a decision that is clearly wrong. And, it says, the ICJ‘s decision is clearly wrong. The ICJ‘s interpretation of Article 36, the majority says, would permit a Convention violation claim to “trump not only procedural default rules, but any number of other rules requiring parties to present their legal claims at the appropriate time for adjudication.” Ante, at 357. That interpretation, it adds, “overlooks the importance of procedural default rules in an adversary system,” and is “inconsistent with the basic framework” of that “system.” Ante, at 356-357.
The majority‘s argument, however, overlooks what the ICJ actually said, overstates what it actually meant, and is inconsistent with what it actually did. In Avena and LaGrand, the ICJ did not say that the Convention necessarily trumps any, let alone all, procedural rules that would otherwise bar assertion of a Convention violation claim. Nor did it say that the Convention necessarily trumps all procedural default rules. Rather, it said that the Convention prohibits application of those rules to a Convention violation claim only “where it has been the failure of the United States [or of a State] itself to inform that may have precluded counsel from being in a position to have raised the question of a violation of the Vienna Convention in the initial trial.” Avena, 2004 I. C. J., at 57, ¶ 113 (emphasis added). Thus, Article 36(2) precludes procedural default only where the defendant‘s failure to bring his claim sooner is the result of the underlying violation. Since procedural default rules themselves typically excuse defaults where a defendant shows “cause and prejudice,” it is difficult to see how this statement “overlooks
Moreover, Avena and LaGrand make clear what the ICJ‘s language taken in context means: The Convention requires effective national remedies; hence local procedural rules must give way (to the Convention‘s “full effect” requirement) when, but only when, it is the failure of the arresting authorities to inform the defendant of his Convention rights that prevented the defendant from bringing his claim sooner. The opinions nowhere suggest that a State must provide a procedural remedy to a defendant who, for example, sleeps on his rights.
Consider, too, what the ICJ did in Avena, a case that clarified the court‘s earlier LaGrand opinion. It did not hold that American courts must ignore their procedural default rules in each of the 54 individual cases at issue. Rather, it held that domestic courts must provide “review and reconsideration” in each case. Avena, 2004 I. C. J., at 72, ¶ 153(9). It nowhere forbids a state court conducting such a “review” to bar claims not timely made provided that the violation did not itself cause the delay. See id., at 65, ¶ 139.
Perhaps the ICJ‘s opinions are open to different interpretations. But how does reading those opinions as creating an extreme rule of law, as reflecting a lack of understanding of the “adversary system,” show “respectful consideration“? To show that kind of respect, we must read the opinions in light of the Convention‘s underlying language and purposes and ask whether, or to what extent, they require modification of a State‘s ordinary procedural rules. See Art. 36(2), 21 U. S. T., at 101 (laws and regulations “must enable full effect to be given to the purposes for which the rights accorded under this Article are intended” (emphasis added)).
Nothing in Avena suggests, for example, that an arrested foreign national who was already aware of his rights under Article 36, or who had a lawyer who was aware of those
The Court also relies on Breard v. Greene, 523 U. S. 371 (1998) (per curiam). In that case, a foreign national, claiming a Convention violation, sought federal habeas corpus. This Court upheld a denial of relief on the ground that the lower courts had correctly found that Breard procedurally defaulted his Convention violation claim by failing to timely raise it in his state-court proceedings. In reaching its conclusion, the Court rejected Breard‘s claim that the Convention trumped the procedural default rule. Its reasons were (1) that “it has been recognized in international law that, absent a clear and express statement to the contrary, the procedural rules of the forum State govern the implementation of the treaty in that State,” id., at 375; (2) that this principle is “embodied in the Vienna Convention itself, which provides that the rights expressed in the Convention ‘shall be exercised in conformity with the laws and regulations of the receiving State,‘” ibid.; and (3) that the federal procedural default rule, as a later-in-time federal statute, superseded any inconsistent provision in the Convention, id., at 376.
I do not believe that Breard controls the outcome of these cases. With respect to the third ground for the Court‘s deci-
Moreover, the ICJ decided Avena and LaGrand after this Court decided Breard. And it is not difficult to reconcile those cases with Breard because they do not directly conflict with Breard‘s result. Rather, they interpret Article 36(2) to require state procedural default rules sometimes to give way to the Convention, namely, when those rules prevent effective remedy by barring assertion of a claim because of a delay caused by the Convention violation itself. I would read Breard as consistent with this interpretation, i. e., as not saying that the Convention never trumps any procedural default rule.
The Court complains that this treatment of Breard fails to give our own opinions “‘respectful consideration.‘” Ante, at 353, n. 4. In fact, our opinions are entitled to far more
And there are other reasons not to place too much reliance on the breadth of Breard‘s language. Breard is a per curiam decision that the Court had to reach within the few hours available between the time a petition for certiorari was filed and a scheduled execution, the decision is fairly recent, and the modification to which I refer requires no more than reading an exception into Breard‘s language, language that in any event was not central to the Court‘s holding.
The modification is appropriate too because the “full effect” proviso in Article 36(2) provides a “clear and express statement” that sometimes the Convention might trump a domestic procedural rule. And in any event, it is not even clear that such a clear statement rule actually exists. Breard‘s statement of a presumption that only a treaty pro-
Indeed, the cases Breard cites for the proposition that a clear and express statement is required to trump a domestic procedural rule seem not to establish it. Sun Oil Co. v. Wortman, 486 U. S. 717, 723 (1988) (Court said only that it was a “rule in international law at the time the Constitution was adopted” that procedural rules “may be governed by forum law even when the substance of the claim must be governed by another State‘s law“; case involved domestic law and the Constitution‘s Full Faith and Credit Clause); Le Roy v. Crowninshield, 15 F. Cas. 362, 365, 371 (No. 8,269) (Mass. 1820) (case involved conflict of laws, not an international treaty); Volkswagenwerk Aktiengesellschaft v. Schlunk, 486 U. S. 694, 700 (1988) (case said that “we almost necessarily must refer to the internal law of the forum state” to find a service of process standard if a treaty “does not prescribe” it); Société Nationale Industrielle Aérospatiale v. United States Dist. Court for Southern Dist. of Iowa, 482 U. S. 522, 539-540, and n. 25 (1987) (case involving a specific treaty, not a general interpretive standard).
Finally, the Court says it would be odd to treat Convention rights more favorably than rights protected by the U. S. Constitution. Ante, at 358-360. But “[a] treaty is in its nature a contract between two nations,” Foster, 2 Pet., at 314, and nations are of course free to agree to grant one another‘s
In sum, I find strong reasons for interpreting the Convention as sometimes prohibiting a state court from applying its ordinarily procedural default rule to a Convention violation claim. The fact that the ICJ reached a similar conclusion in LaGrand and Avena adds strength to those reasons. And I cannot agree with the majority‘s arguments to the contrary.
Consequently, I would remand No. 05-51 so that Bustillo can argue to the Virginia state courts that they should modify their ordinary procedural default requirements. I would leave it to the state courts to determine in the first instance whether state law has provided Bustillo the effective remedy that the Convention requires and how it has done so (whether through “cause and prejudice” exceptions, ineffective-assistance-of-counsel claims, or other ways). Cf. LaGrand, 2001 I. C. J., at 513, ¶ 125 (the “choice of [implementing] means must be left to the United States“).
IV
The final question presented asks whether a Convention violation “result[s] in the suppression” of the evidence, say, a confession, that a foreign national provided police before being informed of his Convention rights. Pet. for Cert. in No. 04-10566, p. i. The majority answers in absolute terms, stating that “suppression is not an appropriate remedy for a violation of [the Convention].” See ante, at 337. I agree with the majority insofar as it rejects the argument that the Convention creates a Miranda-style “automatic exclusionary rule.” Ante, at 344; see also Miranda, 384 U. S., at 471; cf., e. g., Mapp v. Ohio, 367 U. S. 643 (1961); Franks v. Delaware, 438 U. S. 154 (1978). But I do not agree with the absolute nature of its statement. Rather, sometimes suppression could prove the only effective remedy. And, if that is so, then the Convention, which insists upon effective remedies,
Much depends upon the circumstances. It may be true that in “most circumstances, there is likely to be little connection between an Article 36 violation and evidence or statements obtained by police.” Ante, at 349. Miranda surely helps, for it guarantees that police will inform an arrested foreign national of his right to contact a lawyer. But one cannot guarantee in advance that Miranda will adequately cure every seriously prejudicial failure to inform an arrested person of his right to contact his consular post. One can imagine a case, for example, involving a foreign national who speaks little English, who comes from a country where confessions made to the police cannot be used in court as evidence, who does not understand that a state-provided lawyer can provide him crucial assistance in an interrogation, and whose native community has great fear of police abuse. Indeed, Sanchez-Llamas made allegations similar to these in his case. Brief for Petitioner Sanchez-Llamas 5-7; see also Brief for the Government of the United Mexican States as Amicus Curiae 10.
While JUSTICE GINSBURG is correct that a defendant who is prejudiced under the Convention may be able to show that his confession is involuntary under Miranda, ante, at 361, I am not persuaded that this will always be so. A person who fully understands his Miranda rights but does not fully understand the implications of these rights for our legal system may or may not be able to show that his confession was involuntary under Miranda, but he will certainly have a claim under the Vienna Convention. In such a case, suppression of a confession may prove the only effective remedy. I would not rule out the existence of such cases in advance.
Furthermore, the majority is wrong to say that it would “be startling if the Convention were read to require suppression” in such cases because suppression “is an entirely American legal creation.” Ante, at 343. I put to the side the fact
These differences may also help to explain what the majority says is the disturbing circumstance that “nearly all” other signatories to the Convention “refuse to recognize” suppression “as a matter of domestic law,” and therefore that “Sanchez-Llamas would [not] be afforded the relief he seeks here in any of the other 169 countries party to the Vienna Convention.” Ante, at 344. In fact, there are several cases from common-law jurisdictions suggesting that suppression is an appropriate remedy for a Convention violation. See, e. g., Tan Seng Kiah v. Queen (2001) 160 F. L. R. 26 (Crim. App. N. Terr.) (Australian case suppressing confession obtained in violation of statute requiring police to notify defendant of right to contact consulate upon arrest); Queen v. Tan [2001] W. A. S. C. 275 (Sup. Ct. W. Aus. in Crim.) (Australian case considering but declining to suppress evidence based on violation of same statute); Queen v. Partak, 160 C. C. C. 3d, at ¶ 63 (Canada) (concluding that suppression is inappropriate, not because it was never a proper remedy under the Vienna Convention but because the defendant “completely failed to demonstrate any prejudice arising from the failure of the police to notify him of his consular rights“).
I concede the absence of such cases from civil-law jurisdictions. But the criminal justice systems in those nations differ from our own in significant ways. Civil-law nations, for example, typically rely more heavily than do we upon judicial investigation, questioning by a neutral magistrate, the compiling of all evidence into a dossier, and later review of that dossier at trial by judges who may sit without our type of jury. In such a system, formal suppression proceedings may prove less frequent. Judges, as a matter of practice, may simply disregard improperly obtained evidence, they may discount the significance of that evidence, or they may adjust the nature of future proceedings or even the final sentence accordingly. See Damaška, Evidentiary Barriers to Conviction and Two Models of Criminal Procedure: A Comparative Study, 121 U. Pa. L. Rev. 506, 522 (1972) (explaining why many civil law system “provisions regulating the interrogation of defendants are silent as to the admissibility of testimony obtained in violation of proper interrogation procedures“); see also Van Kessel, European Perspectives on the Accused as a Source of Testimonial Evidence, 100 W. Va. L. Rev. 799, 831 (1997) (“Because [civil-law] courts decide both questions of law and of fact, exclusionary rules in [those] courts are more appropriately described as rules of decision than rules of exclusion—what evidence the factfinder may use to support its decision, rather than what evidence may be presented to the fact-finder. The presiding judge is well acquainted with all evidence in the dossier and often must ‘put aside’ or ‘forget about’ evidence which legally cannot be used to support the judgment“); Bradley, The Exclusionary Rule in Germany, 96 Harv. L. Rev. 1032, 1065 (1982) (noting that in the German inquisitorial system, for
Thus, the absence of reported decisions formally suppressing confessions obtained in violation of the Convention tells us nothing at all about whether such nations give “full effect” to the “purposes” of Article 36(1). The existence of cases in such nations where a court denies a defense request to suppress, of course, might well shed light on that nation‘s readiness to provide an effective remedy. The Solicitor General cites one (and only one) such case. See Judgment of Nov. 7, 2001, 5 BGHSt 116 (deciding in light of LaGrand that the Convention creates individual rights, but declining to suppress confession). That is the only support I have found for the claim that somehow the petitioners here are asking the United States to provide that which other countries deny, an effective remedy.
V
The United States joined the Vienna Convention, and urged other nations to join, in order to promote “the orderly and effective conduct of consular relations between States,” and to guarantee “the protection of our citizens abroad.” Vienna Convention on Consular Relations with Optional Protocol, S. Exec. Doc. No. E, 91st Cong., 1st Sess., 60, 75 (1969). In doing so, the United States, along with the other 169 nations that ratified the Convention, undertook a complex task. They sought not only to protect their consular posts, but also to assure that their nationals would have access to those posts when arrested abroad. But how to enforce those
The Convention deals with this problem by including a general provision that both severely limits the treaty‘s intrusion into the functioning of a domestic legal system and also safeguards consular access rights from serious domestic neglect. It does so by stating that those rights shall “be exercised in conformity with the laws and regulations of the receiving State,” provided that those laws and regulations give “full effect” to Article 36(1)‘s purposes. Art. 36(2), 21 U. S. T., at 101.
Applying this provision to our own legal system, I would seek to minimize the Convention‘s intrusion and federal intrusion into the workings of state legal systems while simultaneously keeping faith with the Convention‘s basic objectives. That is why I believe that the Convention here requires individual States to make an exception (akin to a “cause and prejudice” exception) to a state procedural default rule if (1) the defendant‘s failure to raise a claim of a Convention violation in a timely manner itself was a product of that violation, and (2) state law provides no other procedural means through which the State‘s courts can provide “review,” “reconsideration,” and effective relief. Similarly, I would hold that whether the Convention requires a state court to suppress a confession obtained after an Article 36 violation depends on whether suppression is the only remedy available that will effectively cure related prejudice. And because neither state court applied this standard below, I would remand each case for that initial consideration. See 338 Ore., at 269, 108 P. 3d, at 574 (rejecting Sanchez-Llamas’
The interpretation of the Convention that I would adopt is consistent with the ICJ‘s own interpretation and should not impose significant new burdens upon state criminal justice systems. America‘s legal traditions have long included detailed rules for discovering and curing prejudicial legal errors. Indeed, many States already have “cause and prejudice” exceptions likely broad enough to provide the “effective” relief the Convention demands. And, in any event, it leaves the States free to apply their own judicial remedies in light of, and bounded by, the Convention‘s general instructions.
The Court, I fear, does not rise to the interpretive challenge. Rather than seek to apply Article 36‘s language and purposes to the federal-state relationships that characterize America‘s legal system, it simply rejects the notion that Article 36(2) sets forth any relevant requirement. That approach leaves States free to deny effective relief for Convention violations, despite America‘s promise to provide just such relief. That approach risks weakening respect abroad for the rights of foreign nationals, a respect that America, in 1969, sought to make effective throughout the world. And it increases the difficulties faced by the United States and other nations who would, through binding treaties, strengthen the role that law can play in assuring all citizens, including American citizens, fair treatment throughout the world.
Accordingly, I respectfully dissent.
Notes
“1. With a view to facilitating the exercise of consular functions relating to nationals of the sending State:
“(a) consular officers shall be free to communicate with nationals of the sending State and to have access to them. Nationals of the sending State shall have the same freedom with respect to communication with and access to consular officers of the sending State;
“(b) if he so requests, the competent authorities of the receiving State shall, without delay, inform the consular post of the sending State if, within its consular district, a national of that State is arrested or committed to prison or to custody pending trial or is detained in any other manner. Any communication addressed to the consular post by the person arrested, in prison, custody or detention shall also be forwarded by the said authorities without delay. The said authorities shall inform the person concerned without delay of his rights under this sub-paragraph;
“(c) consular officers shall have the right to visit a national of the sending State who is in prison, custody or detention, to converse and correspond with him and to arrange for his legal representation. They shall also have the right to visit any national of the sending State who is in prison, custody or detention in their district in pursuance of a judgment. Nevertheless, consular officers shall refrain from taking action on behalf of a national who is in prison, custody or detention if he expressly opposes such action.
“2. The rights referred to in paragraph 1 of this Article shall be exercised in conformity with the laws and regulations of the receiving State, subject to the proviso, however, that the said laws and regulations must enable full effect to be given to the purposes for which the rights accorded under this Article are intended.” 21 U. S. T., at 100-101.
Before trial, Sanchez-Llamas moved to suppress his statements to police on voluntariness grounds. The trial court denied the motion, finding that clear and convincing evidence established Sanchez-Llamas’ knowing, voluntary, and intelligent waiver of his Miranda rights. Tr. 232 (Nov. 16, 2000); App. to Pet. for Cert. in No. 04-10566, pp. 10–11. Neither the Oregon Court of Appeals nor the Oregon Supreme Court addressed Sanchez-Llamas’ voluntariness challenge, and this Court declined to review the question.In a few cases, as several amici point out, the United Kingdom and Australia appear to have applied a discretionary rule of exclusion for violations of domestic statutes implementing the Vienna Convention. See Brief for United States as Amicus Curiae 26, and n. 9; Brief for National Association of Criminal Defense Lawyers et al. as Amici Curiae 16-23. The dissent similarly relies on two cases from Australia, post, at 394 (opinion of BREYER, J.) (citing Tan Seng Kiah v. Queen (2001) 160 F. L. R. 26 (Crim. App. N. Terr.) and Queen v. Tan [2001] W. A. S. C. 275 (Sup. Ct. W. Aus. in Crim.)), where consular notification rights are governed by a domestic statute that provides rights beyond those required by Article 36 itself. See Crimes Act, No. 12, 1914, § 23p (Australia). The Canadian case on which the dissent relies, post, at 394-395, denied suppression, and concerned only the court‘s general discretionary authority to exclude a
