OPINION OF THE COURT
[
delivered the opinion of the Court.
We decide whether a former Attorney General enjoys immunity from suit for allegedly authorizing federal prosecutors to obtain valid material-witness warrants for detention of terrorism suspects whom they would otherwise lack probable cause to arrest.
I
The federal material-witness statute authorizes judges to “order the arrest of [a] person” whose testimony “is material in a criminal proceeding ... if it is shown that it may become impracticable to secure the presence of the person by subpoena.” 18 U.S.C. § 3144. Material witnesses enjoy the same constitutional right to pretrial release as other federal detainees, and federal law requires release if their testimony “can adequately be secured by deposition, and if further detention is not necessary to prevent a failure of justice.” Ibid.
[
Because this case arises from a motion to dismiss, we accept as true the factual allegations in Abdullah al-Kidd’s complaint. The complaint alleges that, in the aftermath of the September 11th terrorist attacks, then-Attorney General John Ashcroft authorized federal prosecutors and law enforcement officials to use the material-witness statute to detain individuals with suspected ties to terrorist organizations. It is alleged that federal officials had no intention of calling most of these individuals as witnesses, and that they were detained, at Ashcroft’s direction, because federal officials suspected them of supporting terrorism but lacked sufficient evidence to charge them with a crime.
It is alleged that this pretextual detention policy led to the material-witness arrest of al-Kidd, a native-born United States citizen. FBI agents apprehended him in March 2003 as he checked in for a flight to Saudi Arabia. Two days earlier, federal officials had informed a Magistrate Judge that, if al-Kidd boarded his flight, they believed information “crucial” to the prosecution of Sami Omar al-Hussayen would be lost. App. 64. Al-Kidd remained in federal custody for 16 days and on supervised release until al-Hussayen’s trial concluded 14 months later. Prosecutors never called him as a witness.
In March 2005, al-Kidd filed this Bivens action, see Bivens v. Six Unknown Fed. Narcotics Agents,

Qualified immunity shields federal and state officials from money damages unless a plaintiff pleads facts showing (1) that the official violated a statutory or constitutional right, and (2) that the right was “clearly established” at the time of the challenged conduct. Harlow v. Fitzgerald,
Courts should think carefully before expending “scarce judicial resources” to resolve difficult and novel questions of constitutional or statutory interpretation that will “have no effect on the outcome of the case.” Id., at 236-237,
A
The Fourth Amendment protects “[t]he right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures.” An arrest, of course, qualifies as a “seizure” of a “person” under this provision,
[
Dunaway v. New York,
Fourth Amendment reasonableness “is predominantly an objective inquiry.” Indianapolis v. Edmond,
Two “limited exception [s]” to this rule are our special-needs and administrative-search cases, where “actual motivations” do matter. United States v. Knights,
[
Michigan v. Clifford,
Apart from those cases, we have almost uniformly rejected invitations to probe subjective intent. See Brigham City v. Stuart,
That was mistaken. It was not the absence of probable cause that triggered the invalidating-purpose inquiry in Edmond. To the contrary, Edmond explicitly said that it would approve checkpoint stops for “general crime control
[
purposes” that were based upon merely “some quantum of individualized suspicion.”
Needless to say, warrantless, “sus-picionless intrusions pursuant to a general scheme,” id., at 47,
A warrant based on individualized suspicion

(1968), and Knights,
Al-Kidd would read our cases more narrowly. He asserts that Whren es
“[0]nly an undiscerning reader,” ibid., would think otherwise. We referred to probable cause to believe that a violation of law had occurred because that was the legitimating factor in the case at hand. But the analysis of our opinion swept broadly to reject inquiries into motive generally. See id., at 812-815,
[
or administrative regulation, is not accorded to searches that are not made for those purposes,” id., at 811-812,
Because al-Kidd concedes that individualized suspicion supported the issuance of the material-witness arrest warrant; and does not assert that his arrest would have been unconstitutional absent the alleged pretextual use of the warrant; we find no Fourth Amendment violation.
[
B
A Government official’s conduct violates clearly established law when, at the time of the challenged conduct, “[t]he contours of [a] right [are] sufficiently clear” that every “reasonable official would [have understood] that what he is doing violates that right.” Anderson v. Creighton,
At the time of al-Kidd’s arrest, not a single judicial opinion had held that pretext could render an objectively reasonable arrest pursuant to a material-witness warrant unconstitutional. A district-court opinion had suggested, in a footnoted dictum devoid of supporting citation, that using such a warrant for preventive detention of suspects “is an illegitimate use of the statute”—implying (we accept for the sake of argument) that the detention would therefore be unconstitutional. United States v. Awadallah,
[
of what is necessary absent controlling authority: a robust “consensus of cases of persuasive authority.” Wilson v. Layne,
The Court of Appeals’ other cases “clearly establishing” the constitutional violation are, of course, those we rejected as irrelevant in our discussion of whether there was any constitutional violation at all. And the Court of Appeals’ reference to those cases here makes the same error of assuming that purpose is only disregarded when there is probable cause to suspect a violation of law.
The Court of Appeals also found clearly established law lurking in the broad “history and purposes of the Fourth Amendment.”
The same is true of the Court of Appeals’ broad historical assertions. The Fourth Amendment was a response to the English Crown’s use of general warrants, which often allowed royal officials to search and seize whatever and whomever they pleased while investigating crimes or affronts to the Crown. See Stanford v. Texas,
Ashcroft must be forgiven for missing the parallel, which escapes us as well. The principal evil of the general warrant
[
was addressed by the Fourth Amendment’s particularity requirement, Stanford, supra, at 485,
While featuring a District Court’s footnoted dictum, the Court of Appeals made no mention of this Court’s affirmation in Edmond of the “pre-dominan [t]” rule that reasonableness is an objective inquiry,
Qualified immunity gives government officials breathing room to make reasonable but mistaken judgments about open legal questions. When properly applied, it protects “all but the plainly incompetent or those who knowingly violate the law.” Malley, supra, at 341,
[
We hold that an objectively reasonable arrest and detention of a material witness pursuant to a validly obtained warrant cannot be challenged as unconstitutional on the basis of allegations that the arresting authority had an improper motive. Because Ashcroft did not violate clearly established law, we need not address the more difficult question whether he enjoys absolute immunity. The judgment of the Court of Appeals is reversed, and the case is remanded for further proceedings consistent with this opinion.
It is so ordered.
Justice Kagan took no part in the consideration or decision of this case.
Notes
. The Court of Appeals also relied upon Ferguson v. Charleston,
. Justice Ginsburg suggests that our use of the word “suspicion” is peculiar because that word “ordinarily” means “that the person suspected has engaged in wrongdoing.” Post, at 749, n. 3,
. The concerns of Justices Ginsburg and Sotomayor about the validity of the warrant in this case are beside the point. See post, at 748-749,
. We may note in passing that al-Kidd alleges that the Attorney General authorized the use of material-witness warrants for detention of suspected terrorists, but not that he forbade the use of

with whom Justice Ginsburg, Justice Breyer, and Justice Sotomayor join as to Part I, concurring.
I join the opinion of the Court in full. In holding that the Attorney General could be liable for damages based on an unprecedented constitutional rule, the Court of Appeals for the Ninth Circuit disregarded the purposes of the doctrine of qualified immunity. This concurring opinion makes two additional observations.
I
The Court’s holding is limited to the arguments presented by the parties and leaves unresolved whether the Government’s use of the material-witness statute in this case was lawful. See ante, at 740,
[
presence of the person by subpoena.” 18 U.S.C. § 3144. The scope of the statute’s lawful authorization is uncertain. For example, a law-abiding citizen might observe a crime during the days or weeks before a scheduled flight abroad. It is unclear whether those facts alone might allow police to obtain a material witness warrant on the ground that it “may become impracticable” to secure the person’s presence by subpoena. Ibid. The question becomes more difficult if one further assumes the traveler would be willing to testify if asked; and more difficult still if one supposes that authorities delay obtaining or executing the warrant until the traveler has arrived at the airport. These possibilities resemble the facts in this case. See ante, at 734,
In considering these issues, it is important to bear in mind that the material-witness statute might not provide for the issuance of warrants within the meaning of the Fourth Amendment’s Warrant Clause. The typical arrest warrant is based on probable cause that the arrestee has committed a crime; but that is not the standard for the issuance of warrants
II
The fact that the Attorney General holds a high office in the Government must inform what law is clearly established
[
for the purposes of this case. Mitchell v. Forsyth,
When faced with inconsistent legal rules in different jurisdictions, national officeholders should be given some deference for qualified immunity purposes, at least if they implement policies consistent with the governing law of the jurisdiction where the action is taken. As we have explained, qualified immunity is lost when plaintiffs point either to “cases of controlling authority in their jurisdiction at the time of the incident” or to “a consensus of cases of persuasive authority such that a reasonable officer could not have believed that his actions were lawful.” Wilson v. Layne,
A national officeholder intent on retaining qualified immunity need not abide by the most stringent standard adopted anywhere in the United States. And the national officeholder need not guess at when a relatively small set of appellate precedents have established a binding legal rule. If national officeholders were subject to personal liability
[
whenever they confronted disagreement among appellate courts, those officers would be deterred from full use of their legal authority. The consequences of that deterrence must counsel caution by the Judicial Branch, particularly in
The proceedings in this case illustrate these concerns. The Court of Appeals for the Ninth Circuit appears to have reasoned that a Federal District Court sitting in New York had authority to establish a legal rule binding on the Attorney General and, therefore, on federal law enforcement operations conducted nationwide.

with whom Justice Breyer and Justice Sotomayor join, concurring in the judgment.
Is a former U. S. Attorney General subject to a suit for damages on a claim that he instructed subordinates to use the material-witness statute, 18 U.S.C. § 3144, as a pretext to detain terrorist suspects preventively? Given Whren v. United States,
[
on the merits; as she observes, post, at 751,
In addressing al-Kidd’s Fourth Amendment claim against Ashcroft, the Court assumes at the outset the existence of a validly obtained, material witness warrant. Ante, at 733, 744,
Casting further doubt on the assumption that the warrant was validly obtained, the Magistrate Judge was not told that al-Kidd’s parents, wife, and children were all citizens and residents of the United States. In addition, the affidavit misrepresented that al-Kidd was about to take a one-way flight to Saudi Arabia, with a
[
misrepresentations, there is strong cause to question the Court’s opening assumption—a valid material witness warrant—and equally strong reason to conclude that a merits determination was neither necessary nor proper.
[
I also agree with Justice Kennedy that al-Kidd’s treatment presents serious questions, unaddressed by the Court, concerning “the [legality of] the Government’s use of the material-witness statute in this case” Ante, at

employed to achieve objectives that could be accomplished in so many alternative and less harsh methods, would not support a conclusion that the purpose for which they were imposed was to punish.”).
However circumscribed al-Kidd’s Bivens claim against Ashcroft may have been, see Bivens v. Six Unknown Fed. Narcotics Agents,
. Nowhere in al-Kidd’s complaint is there any concession that the warrant gained by the FBI agents was validly obtained. But cf. ante, at 740, n. 3,
. Judicial officers asked to issue material witness warrants must determine whether the affidavit supporting the application shows that “the testimony of a person is material in a criminal proceeding’’ and that “it may become impracticable to secure the presence of the person by subpoena.’’ 18 U.S.C. § 3144. Even if these conditions are met, issuance of the warrant is discretionary. Ibid, (“judicial officer may order the arrest of the person’’ (emphasis added)). Al-Kidd’s experience illustrates the importance of vigilant exercise of this checking role by the judicial officer to whom the warrant application is presented.
The affidavit used to secure al-Kidd’s detention was spare; it did not state with particularity the information al-Kidd purportedly possessed, nor did it specify how al-Kidd’s knowledge would be material to Sami Omar al-Hussayen’s prosecution. As to impracticability, the affidavit contained only this unelaborated statement: “It is believed that if Al-Kidd travels to Saudi Arabia, the United States Government will be unable to secure his presence at trial via subpoena.’’ App. 64. Had the Magistrate Judge insisted on more concrete showings of materiality and impracticability, al-Kidd might have been spared the entire ordeal.
. The Court thrice states that the material witness warrant for al-Kidd’s arrest was “based on individualized suspicion.’’ Ante, at 738, 740,
This Court’s decisions, until today, have uniformly used the term “individualized suspicion” to mean “individualized suspicion of wrongdoing." See Indianapolis v. Edmond,
The Court’s suggestion that the term “individualized suspicion’’ is more commonly associated with “know[ing] something about [a] crime’’ or “throwing ... a surprise birthday party’’ than with criminal suspects, ante, at 738, n. 2,
. The District Court determined that al-Kidd’s factual allegations against FBI agents regarding their “misrepresentations and omissions in the warrant application, if true, would negate the possibility of qualified immunity [for those agents].” Memorandum Order in No. cv:05-093 (D Idaho, Sept. 27, 2006), p. 18. The agents took no appeal from this threshold denial of their qualified immunity plea.
Concurrence Opinion
with whom Justice Ginsburg and Justice Breyer join, concurring in the judgment.
I concur in the Court’s judgment reversing the Court of Appeals because I agree with the majority’s conclusion that Ashcroft did not violate clearly established law. I cannot join the majority’s opinion, however, because it unnecessarily “resolve [s] [a] difficult and novel questio[n] of constitutional . . . interpretation that will ‘have no effect on the outcome of the case.’ ’’Ante, at 735,
Whether the Fourth Amendment permits the pretextual use of a material witness warrant for preventive detention of an individual whom the Government has no intention of using at trial is, in my view, a closer question than the majority’s
[
opinion suggests. Although the majority is correct that a government official’s subjective intent is generally “irrelevant in determining whether that officer’s actions violate the Fourth Amendment,” Bond v. United States,
The majority’s constitutional ruling is a narrow one premised on the existence of a “valid material-witness warran[t],” ante, at 733,
[
I also join Part I of Justice Kennedy’s concurring opinion. As that opinion makes clear, this case does not present an occasion to address the proper scope of the material witness statute or its constitutionality as applied in this case. Indeed, nothing in the majority’s opinion today should be read as placing this Court’s imprimatur on the actions taken by the Government against al-Kidd. Ante, at 744,
