What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.

CHIEF Justice Roberts
delivered the opinion of the Court.
The State of Louisiana charged petitioner Juan Smith with killing five people during an armed robbery. At Smith’s trial a single witness, Larry Boatner, linked Smith to the crime. Boatner testified that he was socializing at a friend’s house when Smith and two other gunmen entered the home, demanded money and drugs, and shortly thereafter began shooting, resulting in the death of five of Boatner’s friends. In court Boatner identified Smith as the first gunman to come through the door. He claimed that he had been face to face with Smith during the initial moments of the robbery. No other witnesses and no physical evidence implicated Smith in the crime.
The jury convicted Smith of five counts of first-degree murder. The Louisiana Court of Appeal affirmed Smith’s conviction. State v. Smith, 797 So. 2d 193 (2001). The Louisiana Supreme Court denied review, as did this Court. 2001-2416 (La. 9/13/02), 824 So. 2d 1189; 537 U. S. 1201 (2003).
Smith then sought postconviction relief in the state courts. As part of his effort, Smith obtained files from the police investigation of his case, including those of the lead investigator, Detective John Ronquillo. Ronquillo’s notes contain statements by Boatner that conflict with his testimony identifying Smith as a perpetrator. The notes from the night of the murder state that Boatner “could not . . . supply a description of the perpetrators other then [sic] they were black males.” App. 252-253. Ronquillo also made a handwritten account of a conversation he had with Boatner five days after the crime, in which Boatner said he “could not ID anyone because [he] couldn’t see faces” and “would not know them if [he] saw them.” Id., at 308. And Ronquillo’s typewritten report of that conversation states that Boatner told Ron-quillo he “could not identify any of the perpetrators of the murder.” Id., at 259-260.
Smith requested that his conviction be vacated, arguing, inter alia, that the prosecution’s failure to disclose Ronquil-lo’s notes violated this Court’s decision in Brady v. Maryland, 373 U. S. 83 (1963). The state trial court rejected Smith’s Brady claim, and the Louisiana Court of Appeal and Louisiana Supreme Court denied review. We granted cer-tiorari, 564 U. S. 1004 (2011), and now reverse.
Under Brady, the State violates a defendant’s right to due process if it withholds evidence that is favorable to the defense and material to the defendant’s guilt or punishment. See 373 U. S., at 87. The State does not dispute that Boat-ner’s statements in Ronquillo’s notes were favorable to Smith and that those statements were not disclosed to him. The sole question before us is thus whether Boatner’s statements were material to the determination of Smith’s guilt. We have explained that “evidence is ‘material’ within the meaning of Brady when there is a reasonable probability that, had the evidence been disclosed, the result of the proceeding would have been different.” Cone v. Bell, 556 U. S. 449, 469-470 (2009). A reasonable probability does not mean that the defendant “would more likely than not have received a different verdict with the evidence,” only that the likelihood of a different result is great enough to “undermine[] confidence in the outcome of the trial.” Kyles v. Whitley, 514 U. S. 419, 434 (1995) (internal quotation marks omitted).
We have observed that evidence impeaching an eyewitness may not be material if the State’s other evidence is strong enough to sustain confidence in the verdict. See United States v. Agurs, 427 U. S. 97,112-113, and n. 21 (1976). That is not the case here. Boatner’s testimony was the only evidence linking Smith to the crime. And Boatner’s undisclosed statements directly contradict his testimony: Boatner told the jury that he had “[n]o doubt” that Smith was the gunman he stood “face to face” with on the night of the crime, but Ronquillo’s notes show Boatner saying that he “could not ID anyone because [he] couldn’t see faces” and “would not know them if [he] saw them.” App. 196,200, 308. Boatner’s undisclosed statements were plainly material.
The State and the dissent advance various reasons why the jury might have discounted Boatner’s undisclosed statements. They stress, for example, that Boatner made other remarks on the night of the murder indicating that he could identify the first gunman to enter the house, but not the others. That merely leaves us to speculate about which of Boatner’s contradictory declarations the jury would have believed. The State also contends that Boatner’s statements made five days after the crime can be explained by fear of retaliation. Smith responds that the record contains no evidence of any such fear. Again, the State’s argument offers a reason that the jury could have disbelieved Boat-ner’s undisclosed statements, but gives us no confidence that it would have done so.
The police files that Smith obtained in state postconviction proceedings contain other evidence that Smith contends is both favorable to him and material to the verdict. Because we hold that Boatner’s undisclosed statements alone suffice to undermine confidence in Smith’s conviction, we have no need to consider his arguments that the other undisclosed evidence also requires reversal under Brady.
The judgment of the Orleans Parish Criminal District Court of Louisiana is reversed, and the case is remanded for further proceedings not inconsistent with this opinion.
It is so ordered.
