People v. Washington, 86 N.Y.2d 208 (1995)
A prosecutor’s duty to disclose exculpatory material under Brady v. Maryland extends to evidence impeaching the credibility of a prosecution witness, especially if that witness’s testimony may be determinative of the defendant’s guilt or innocence.
Summary
Defendant was convicted of murder and robbery based largely on informant testimony. After his conviction, he sought to vacate the judgment, presenting affidavits from informants recanting their testimony and alleging prosecutorial misconduct. The New York Court of Appeals held that the trial court erred in denying a hearing on whether the prosecution failed to disclose information that could have impeached a key witness. The court emphasized that prosecutors must disclose evidence affecting witness credibility, and the failure to do so may warrant a new trial.
Facts
Regina Carter was killed during a robbery. Defendant was arrested based on statements from four police informants alleging he confessed to the crime. Two informants, Washington and McKinney, testified at trial. Years after his conviction, Defendant sought to vacate the judgment, submitting affidavits: Washington and McKinney recanted their trial testimony and Youmans, another informant who did not testify at trial, stated he told the prosecutor that Washington’s statement was false and induced by police promises. The prosecutor did not disclose Youmans’ recantation to the defense before trial.
Procedural History
The Supreme Court denied Defendant’s motion to vacate the judgment without a hearing. The Appellate Division affirmed both the conviction and the denial of the motion. The New York Court of Appeals granted leave to appeal and modified the Appellate Division’s order, remitting the case for a hearing on the Brady issue.
Issue(s)
Whether the prosecutor’s failure to disclose that a potential witness, Youmans, had informed the prosecutor that another witness, Washington, had fabricated his testimony constituted a violation of Defendant’s due process rights under Brady v. Maryland, warranting a hearing on Defendant’s motion to vacate the judgment of conviction.
Holding
Yes, because the prosecutor has a duty to disclose exculpatory evidence, including evidence that could impeach the credibility of a key prosecution witness, and Youmans’ statement to the prosecutor suggested that Washington’s testimony was fabricated.
Court’s Reasoning
The Court of Appeals determined that Youmans’ affidavit, stating he informed the prosecutor that Washington’s testimony was false, constituted potential Brady material. The court emphasized that a prosecutor’s duty extends to disclosing evidence that impeaches the credibility of a prosecution witness, particularly when that witness’s testimony is crucial to the case. The court cited Giglio v. United States, noting that the “good faith” of a prosecutor is not a valid excuse for nondisclosure. The court stated, “A prosecutor’s duty of disclosing exculpatory material extends to disclosure of evidence impeaching the credibility of a prosecution witness whose testimony may be determinative of guilt or innocence.” Because the People’s papers did not concede the truth of Youmans’ averments, and Youmans’ statements were not conclusively refuted, a hearing was required to determine whether Youmans communicated undisclosed Brady material to the prosecution. The Court directed the hearing court to determine whether the undisclosed evidence created a reasonable doubt that did not otherwise exist. If so, the conviction must be vacated and a new trial ordered; otherwise, the motion to vacate should be denied.
