Greg Marvin Matthew appeals the district court’s denial of his petition for a writ of habeas corpus, arguing that the court erred in ruling that in pleading nolo con-tendere, he waived his claim that the State violated his constitutional rights when it failed to disclose allegedly material exculpatory information. We affirm.
I. FACTS AND PROCEDURAL BACKGROUND
On January 26, 1994, Greg Marvin Matthew, having been accused of raping his step-daughter, pleaded nolo contendere to the charge of aggravated sexual assault of a child. After the entry of the plea, the state trial court found Matthew guilty of aggravated sexual assault of a child and sentenced him to a sixteen-year term of imprisonment. Matthew subsequently filed a direct appeal, which was dismissed for lack of jurisdiction.
On February 28, 1995, Matthew filed an application for habeas relief in state court. He argued that his counsel had been ineffective and that the State had failed to disclose exculpatory evidence. The state trial court, in written reasons, found that Matthew’s counsel was not ineffective but did not make any specific findings or conclusions regarding Matthew’s claim that the prosecutor had withheld exculpatory evidence. The Texas Court of Criminal Appeals denied Matthew’s habeas application without an evidentiary hearing and without written reasons.
In October, 1995, Matthew filed a petition for a writ of habeas corpus in federal district court.
1
He averred that the prosecution “failed to disclose two or more exhibits of exculpatory evidence which would have established [his] innocence to the charge.” Relying on
Brady v. Maryland,
Noting that several circuits had rejected the respondent’s waiver argument, the magistrate judge to whom the matter was preliminarily assigned concluded that Matthew’s plea did not waive his “Brady claim.” The magistrate judge reasoned that the allegation that the prosecution had withheld evidence, if true, would affect “the very integrity of the plea process.” The magistrate judge then ordered that an evidentiary hearing be held.
Before receiving testimony at the evi-dentiary hearing, the magistrate judge admitted into evidence ten exhibits, consisting of documents that the assistant district attorney (“ADA”) had received from Child Protective Services (“CPS”). Among these documents were affidavits and re *357 ports describing instances of the victim denying that she had been sexually abused and asserting that Matthew “did not do anything to [her] in the past.” Those statements preceded the victim’s “outcry” of abuse. One affidavit, completed by the victim’s case worker, refers to a post-outcry statement by the victim indicating that an episode of sexual abuse had taken place on Christmas. 2 The documents also include a letter from the victim’s mother, case-worker notes and psychiatric assessments, and medical reports indicating that the victim showed physical signs of severe sexual abuse.
At the evidentiary hearing, the magistrate judge heard testimony from the petitioner, the attorney who represented him at his plea hearing, and the ADA who handled the case for the State. The magistrate judge also received proffers from five witnesses offered by the respondent to challenge the materiality of the undisclosed evidence. The ADA testified that he provided Matthew’s attorney with a copy of the indictment, the probable cause affidavit, and a report of a medical examination revealing findings consistent with “multiple episodes of vaginal penetration.” He was unable to rеcall providing Matthew with any other documents, but he indicated that he would not have turned over the CPS documents without a court order, which had not been issued. 3 The ADA said he did not consider the withheld documents to be exculpatory because he viewed the victim’s pre-outcry denials to be typical of a “delayed outcry” situation.
Matthew’s counsel at the plea hearing testified that he recalled reviewing the prosecutor’s report, the police report, the indictment, and a medical report. He also testified that he had not conducted any additional discovery or investigation. He stated that Matthew had denied the abuse and had focused on obtaining the shortest possible sentence.
Matthew testified that his lawyer had shown him only a medical report and the capias warrant. He said that he had maintained his innocence to his attorney and, as the record reflects, throughout the nolo contendere plea colloquy. He claimed that, after being sentenced, he wrote to CPS and requested records related to the investigation. He initially received a medical report, the case worker’s affidavit noting the accusation of abuse on Christmas, and the affidavit in which the victim denied that Matthew had “do[ne] anything to [her] in the past.” Matthew asserted that he was unaware that the victim had alleged abuse on Christmas and that, had he known of this information, he would have supplied an alibi placing him elsewhere at the time. He also indicated that he thought that CPS had brainwashed his step-daughter, and he insisted that he would have gone to trial if he had known about the undisclosed documents.
The parties filed post-evidentiary hearing briefs. The magistrate judge again rejected the respondent’s argument that Matthew waived his “Brady claim” by pleading nolo contendere. Despite characterizing the case against Matthew as strong, he found that the withheld evidence was material, concluding that had the evidеnce been disclosed, Matthew would have refused to plead nolo contende-re and insisted on having a trial. The magistrate judge also found Matthew’s ineffective-assistance-of-counsel claim to be without merit.
Matthew filed untimely objections to the magistrate’s report, arguing that the magistrate judge had erred in finding that his ineffective-assistance-of-counsel claim was without merit. The respondent filed an untimely motion for an extension of time within which to file objections to the mag *358 istrate’s report. The district court granted the motion, and the respondent subsequently filed objections, arguing that the magistrate judge had applied the wrong standard to determine the materiality of undisclosed evidence in a guilty or nolo contendere plea situation and had erred in finding that the undisclosed evidence was material. The respondent further averred that the magistrate judge had erred in finding that Matthew’s nolo contendere plea did not waive his “Brady claim.” Finally, the respondеnt argued that the magistrate judge should not have considered Matthew’s ineffective-assistance-of-counsel claim and should have held instead that the claim was waived by his plea.
The district court adopted the magistrate judge’s findings with regard to the claim of ineffective assistance of counsel but declined to accept his recommendation with regard to the claim that the State failed to disclose exculpatory evidence. It characterized as an understatement the magistrate judge’s description of the case against Matthew as being strong, and noted that efforts of Matthew’s lawyers were directed at all times at obtaining plea offers of a sentence acceptable to Matthew. Based on its reading of the law in this circuit, the district court held that Matthew’s nolo contendere plea waived his “Brady claim.” Accordingly, the district court did not resolve the question whether the undisclosed evidence was material.
Matthew filed an аpplication for a certificate of probable cause (“CPC”), arguing only that the district court erred in finding that his nolo contendere plea waived his “Brady claim.” He also filed a notice of appeal. The district court denied the request for a CPC. This court granted a CPC 4 to address the question whether a plea of nolo contendere waives any Brac%-based challenge to the plea.
II. WHETHER MATTHEW’S CLAIM IS TEAG LA-BARRED
This court has not yet resolved whether a nolo contendere or guilty plea waives a subsequent Brady-based challenge.
See Barnes v. Lynaugh,
“A threshold question in every habeas case ... is whether the court is obligated to apply the
Teague
rule to the defendant’s claim.”
Caspari v. Bohlen,
The
Teague
rule precludes us from applying “new constitutional rules of criminal procedure ... to those cases which have become final before the new rules are announced.”
Teague,
Matthew entered his plea on January 26, 1994. Although he attempted to appeal his conviction, his direct appeal was dismissed on July 18, 1994 because Matthew failed to acquire the court’s permission before appealing.
See Lyon v. State,
A. A New Rule of Criminal Procedure ?
An assessment of whether a new rule would be required in order for Matthew to prevail necessitates an understanding of the propositions Matthew must establish in order to be successful.
Cf. Gray v. Netherland,
1. A Brady Violation?
Under
Brady v. Mainland,
The prosecutor’s duty to disclose material exculpatory information is based in the Due Process Clause of the Fourteenth Amendment, and exists to ensure that the accused receives a fair trial, i.e., that an
impartial party’s
assessment of the defendant’s guilt is based on all the available evidence.
See Mooney v. Holohan,
The subsequent inclusion of impeachment evidence under the
Brady
rule,
see United States v. Bagley,
The Court’s definition of “material information” also reflects the
Brady
rule’s purpose of ensuring a fair trial. The state’s obligation to disclose favorable information extends only to information that is material.
See Bagley,
The Brady rule’s focus on protecting the integrity of trials suggests that where no trial is to occur, there may be no constitutional violation. While describing the purpose of the Brady rule and of the rule’s materiality requirement, the Bagley Court noted that
unless the omission deprived the defendant of a fair trial, there was no constitutional violation requiring that the verdict be set aside; and absent a constitutional violation, there was no breach of the prosecutor’s constitutional duty to disclose....
... But to reiterate a critical point, the prosecutor will not have violated his constitutional duty of disclosure unless his omission is of sufficient significance to result in the denial of the defendant’s right to a fair trial.
Bagley,
In light of the Court’s Brady v. Maryland line of cases, it is apparent to us that, at a minimum, a state court would not have felt compelled to hold that the prosecutor’s failure to supply Matthew with the CPS documents prior to entry of his plea constituted a Brady violation. Matthew, in order to establish that a prosecutor’s failure to disclose exculpatory information prior to entry of a guilty plea is a Brady violation, would require adoption of a new rule — one that seeks to proteсt a defendant’s own decision making regarding the costs and benefits of pleading and of going to trial.
Our conclusion that Matthew seeks a new rule is not at odds with cases he cites in support of his arguments. By October 1994, a number of court opinions had suggested that pleas could be collaterally attacked on grounds that the state failed to disclose material exculpatory information.
See, e.g., Tate v. Wood,
The Second Circuit’s approach in
Miller
and
Tate
links directly nondisclosure and the Due Process Clause. However, in light of the Court’s holdings, the Second Circuit’s approach would appear to adopt a new rule. The
Miller
court adapted the Supreme Court’s materiality test in order for it to be applicable to the plea context.
See
State courts’ decisions,
see Caspari,
On the basis of our review of the legal landscape existing in October 1994, we cannot conclude that a state court would have felt compelled to decide that a prosecutor’s failure to disclose exculpatory information prior to entry of a guilty or nolo contendere plea was a Brady violation, or otherwise a violation of the Due Process Clause. We turn next to a consideration of whether a state court would have seen the nondisclosure of which Matthew complains as rendering his plea invalid. 15
2. An Invalid Plea?
It has long been the case that a valid guilty plea bars habeas review of most non-jurisdictional claims alleging antecedent violations of constitutional rights.
See Tollett v. Henderson,
Matthew’s claim does not challenge the power of the State to bring him into court. Thus, the only means available for challenging his conviction is to claim that his plea is invalid, i.e., it was not knowingly and voluntarily entered into.
See Mabry v.
Johnson,
The test for determining a guilty plea’s validity is “ ‘whether the plea represents a voluntary and intelligent choice among the alternative courses of action open to the defendant.’ ”
Hill,
Although the Court’s opinions have often used both “voluntary” and “intelligent” to describe various characteristics of constitutionally valid guilty pleas,
17
several conditions appear necessary. The defendant pleading guilty must be competent,
see Brady v. United States,
Matthew’s claim is not that the state threatened him, or that the state made and then broke promises made to him. He does not allege that he was incompetent. 18 *366 He does not suggest that he did not understand the nature of the charges against him or of the constitutional protection he was waiving. Matthew does not challenge the factual basis for his plea. 19 He no longer has a claim of ineffective counsel. In short, Matthew does not suggest that his plea lacks any of the characteristics that the Court has held make up a voluntary and intelligent plea.
On this alone, a state court reviewing Matthew’s conviction could determine that his plea was valid. Moreover, it would be supported in this conclusion by the fact that Matthew stated at his hearing that his plea was freely and voluntаrily made, and that he understood the nature of the charges against him and the nature of the constitutional rights he was waiving. These statements act to create a presumption that in fact the plea is valid.
See Blackledge v. Allison,
Matthew’s argument reduces to one based on the assessment that had he had the undisclosed information, he would have made a different decision, i.e., had he known of the documents and their contents, he would, as he stated in his eviden-tiary hearing, “have rolled the dice and risked going to jail for ninety-nine years instead of pleading nolo to a sixteen-year plea bargain.” The question, therefore, is whether a state court would have felt compelled by existing law to hold that this made Matthew’s plea invalid.
We conclude that the answer to this question is “no.” A state court reviewing
Brady v. United States,
one of the more important cases setting forth the requirements of valid guilty pleas, would find that the Court rejected an argument very similar to Matthew’s.
See
To gain an understanding of what more may be required to show the plea is “invalid as an involuntary act,” the state court wоuld undoubtedly turn to cases holding that a plea does not preclude collateral attack on grounds that the state failed to disclose favorable information.
See, e.g., Tate v. Wood,
The state court reviewing these cases also would be confronted with reasoning supporting their holdings that is at odds with Supreme Court opinions. Fоr example, one reason given for holding that a defendant pleading guilty may attack the plea claiming nondisclosure is that courts cannot “satisfy themselves that pleas of guilty are voluntarily and intelligently made by competent defendants with adequate advice of counsel and that there is nothing to question the accuracy and reliability of the defendants’ admissions that they committed the crimes with which they are charged,”
Brady v. United States,
Here petitioner does not contend that his plea was “involuntary” or “unintelligent” simply because the State through its officials failed to supply him with information about his parole eligibility date. We have never held that the United Stаtes Constitution requires the State to furnish a defendant with information about parole eligibility in order for the defendant’s plea of guilty to be voluntary, and indeed such a constitutional requirement would be inconsistent with the current rules of procedure governing the entry of guilty pleas in the federal courts. See Fed. Rule Crim. Proc. 11(c).
Even more problematic is reasoning based on the Court’s observation in
Brady v. United States,
The state court would also be faced with a basic problem: If it were the case that defendants assessing whether to plead guilty must be given an opportunity to weigh the state’s case in order to make a voluntary and intelligent decision, requiring that “material” exculpatory information be provided prior to entry of a guilty plea would not achieve the objective. As the Court noted in
Agurs,
In light of our survey of the legal landscape, we again find that Matthew requires a new rule in order to prevail.
24
As a result, we turn next to an assessment of whether the new rules fall into either of the exceptions recognized by the Court. If they do, we may announce them, and apply them to Matthew’s case.
Penry v. Lynaugh,
B. Exceptions to the Nonretroactivity Principle
The
Teague
Court identified two exceptions to the nonretrоactivity principle. Under the first exception, a new rule “should be applied retroactively if it places ‘certain kinds of primary, private individual conduct beyond the power of the criminal law-making authority to proscribe.’ ”
Teague v. Lane,
Under the second exception, a new rule should be applied retroactively if it is a “ ‘watershed rule[ ] of criminal procedure’ implicating the fundamental fairness and accuracy of the criminal proceeding.”
Saffle v. Parks,
Matthew argues strenuously that, if we were to find that new rules would be required, those rules would fall under the second exception. Although we in no way
*370
condone the purposeful withholding of information in order to elicit a guilty plea from a defendant, we cannot agree that the rules Matthew seeks to have applied to his case fall within Teague’s second exception. In light of the existing protections afforded individuals pleading guilty or nolo contendere, we doubt that new rules allowing individuals to challenge the validity of their pleas on grounds that the state failed to supply them with exculpatory information prior to entry of their plea will seriously enhance the accuracy of convictions. Moreover, we do not see the new rules as on par with a defendant’s right to be represented by counsel in all criminal trials for serious offenses, which the Court in
Saffle v. Parks
viewed as the paradigmatic example of a rule falling within the second exception.
See
III. CONCLUSION
For the foregoing reasons, we find that the nonretroactivity rule announced in Teague v. Lane prohibits us from granting the relief that Matthew seeks. As a result, we must affirm the district court’s denial of Matthew’s petition for a writ of habeas corpus.
AFFIRMED.
Notes
. Matthew initially proceeded pro se but then requested and was granted appointment of counsel.
. Matthew's step-daughter alleged repeated sexual abuse. The indictment charged Matthew with the sexual assault of a child on or about April 1, 1993.
. The district court noted that “C.P.S. files are confidential under Texas law and their contents are not to be disclosed absent court order.”
. Matthew filed his habeas petition prior to the effective date of the Antiterrorism and Effective Death Penalty Act of 1996, Pub.L. No. 104-132, 110 Stat. 1214 (1996), so that Act's provisions do not govern the disposition of his petition.
See Lindh v. Murphy,
. In
Barnes,
we determined that we did not need to address issues similar to those Matthew raises because we did not view the information thаt was allegedly not disclosed to be
Brady
material.
See
. Before oral argument in this case, the court directed the parties to address the question whether Matthew’s petition sought the application of a new rule of constitutional criminal procedure such that Teague would counsel against a grant of habeas relief.
. Matthew's direct appeal stated that statements were coerced and that “Defendant will show that all original statements by the Plan-tif [sic] contained information that would have the Defendant acquited [sic] and these statements and facts were not brought forth.”
. Alternatively, he would need to establish that the State's failure to disclose “material" exculpatory information prior to entry of his plea violates the Due Process Clause because it rendered the plea invalid or otherwise constitutionally suspect. This line of reasoning could include an argument that the definition of "material” information should be derived from the Brady v. Maryland line of cases. Because this line of reasoning, like the first, depends on thе finding that Matthew’s plea was invalid, any conclusions we draw with respect to the legal landscape regarding the validity of pleas would apply to this alternative reasoning.
. Under Texas law, a plea of nolo contendere has the same legal effect as a plea of guilty, with an exception not applicable here.
See
Tex. Code Crim. P. Ann. art. 27.02(5). In any event, we may apply law regarding guilty pleas to pleas of nolo contendere.
See Carter v. Collins,
. In subsequent cases, the Court has clarified the materiality requirement, and in so doing has underscored the fundamental tie to the concept of a fair trial.
See, e.g., Kyles v. Whitley,
. Issues related to defense strategies and other pretrial decisions were also touched upon in
Bagley,
.The Court has recently restated the distinction between a Brady violation and a failure to disclose information:
[T]he term “Brady violation” is sometimes used to refer to any breach of the broad obligation to disclose exculpatory evidence — that is, to any suppression of so-called "Brady material” — although, strictly speaking, there is never a real "Brady violation” unless the nondisclosure was so serious that there is a reasonable probability that the suppressed evidence would have produced a different verdict.
*362
Strickler v. Greene,
. Some Court opinions contain language that appears to broaden the reach of
Brady v. Maryland
to encompass all "proceedings” and "pretrial” decisions.
See, e.g., United States
v.
Bagley,
Reference to pretrial decisions was no doubt triggered by arguments that reliance on the prosecutor's incomplete responses to a request for
Brady
material could cause defense counsel to "abandon lines of independent investigation, defenses, or trial strategies that it otherwise would have pursued.”
Bag-ley,
. Compare Miller's test with the Court’s description in
Hill v. Lockhart,
In many guilty plea cases, the "prejudice” inquiry will closely resemble the inquiry engaged in by courts reviewing ineffective-assistance challenges to convictions obtained through a trial. For example, where the alleged error of counsel is a failure to investigate or discover potentially exculpatory evidence, the determination whether the error "prejudiced” the defendant by cаusing him to plead guilty rather than go to trial will depend on the likelihood that discovery of the evidence would have led counsel to change his recommendation as to the plea. This assessment, in turn, will depend in large part on a prediction whether the evidence likely would have changed the outcome of a trial... [Tjhese predictions of the outcome at a possible trial, where necessary, should be made objectively ....
Hill,
. Although we conclude that Matthew’s claim requires a new rule with regard to the first proposition he asserts — that the nondisclosure was a Brady violation — we think we must also assess whether Matthew's second proposition — that the nondisclosure rendered his plea invalid — would also require a new rule. This is due primarily to the alternative argument set forth in note 8 supra. Even if the nondisclosure is not a Brady violation, it may be argued (and Matthew appears on occasion to be arguing) that it made it impossible for Matthew to enter a knowing and intelligent plea.
. Although courts mаy consider whether a factual basis for a guilty plea exists in their assessments of its validity, it has generally been held that the Constitution does not require that they ensure such a basis exists.
See, e.g., Higgason v. Clark,
.
Compare Brady v. United States,
.In
Ex parte Lewis,
. Texas law requires that "in no event shall a person charged be convicted upon his plea without sufficient evidence to support the same.” Tex Code Crim. P. Ann. art. 1.15 (West 1991). As is allowed under article 1.15, Matthew consented to the stipulation of evidence against him.
. In reviewing the legal landscape, the state court would also find a number of decisions holding that a guilty plea waives a
Brady-based
challenge.
See Smith v. United States,
. The
“Brady
Trilogy” refers to three "guilty plea” cases the Supreme Court decided on the same day:
Brady v. United States,
. What courts are required to do before accepting a guilty plea has been laid out in the Federal Rules, and in a line of cases beginning with
Boykin v. Alabama,
. Under Rule 11(f), the court may use any means appropriate,
see
Fed. R. Crim. P. 11 advisory committee note (1974 Amendments), to determine "that the conduct which the defendant admits constitutes the offense charged in the indictment or information or an offense included therein to which the defendant has pleaded guilty.” Fed. R. Crim. P. 11 advisory committee notes (1966 Amendments). The Rule does not require that the court "weigh evidence to assess whether it is even more likely than not that the defendant is guilty.”
United States v. Maher,
. We are aware of the Court's statements in
Bousley v. United States,
