People v. Jackson, 78 N.Y.2d 638 (1991)
A defendant seeking to vacate a conviction via a CPL 440.10 motion based on a Rosario violation (failure to disclose a witness’s prior statement) after exhausting direct appeals must demonstrate a reasonable possibility that the failure to disclose the Rosario material contributed to the verdict.
Summary
Erick Jackson was convicted of felony murder and arson. After his direct appeal failed, he moved to vacate his conviction under CPL 440.10, alleging a Rosario violation. The prosecution had failed to disclose a memorandum containing a synopsis of an interview with a prosecution witness. The Court of Appeals addressed whether the per se error rule for Rosario violations, typically applied on direct appeal, extends to collateral review via CPL 440.10 motions. The Court held that it does not; a defendant must demonstrate prejudice resulting from the Rosario violation when seeking relief under CPL 440.10 after exhausting direct appeals, requiring a showing that the non-disclosure reasonably could have contributed to the verdict.
Facts
Erick Jackson was convicted of felony murder and arson in connection with a fire at a supermarket that killed six firefighters.
After his conviction was affirmed on direct appeal, Jackson filed a CPL 440.10 motion to vacate his conviction.
The motion alleged ineffective assistance of counsel and a Brady violation. The trial court also considered a Rosario claim.
The People conceded that a memorandum summarizing an interview with a fire marshal, who later testified, was not provided to the defense, and that it was not a duplicative equivalent of other disclosed materials.
Procedural History
Jackson was convicted of felony murder and arson; his conviction was affirmed on direct appeal.
Jackson then filed a CPL 440.10 motion to vacate his conviction, which was granted by the trial court based on a Rosario violation, applying the per se error rule.
The Appellate Division affirmed, also applying the per se error rule.
The People appealed to the Court of Appeals.
Issue(s)
Whether the per se error rule applicable to Rosario violations on direct appeal extends to motions to vacate a conviction under CPL 440.10 after direct appeal has been exhausted, or whether the defendant must demonstrate prejudice.
Holding
No, because a defendant who has exhausted direct appeal and seeks to raise a Rosario claim via a CPL 440.10 motion must demonstrate a reasonable possibility that the failure to disclose the Rosario material contributed to the verdict.
Court’s Reasoning
The Court distinguished between direct appeals and collateral attacks via CPL 440.10 motions.
CPL 440.10(1)(f), relating to “improper and prejudicial conduct,” is the appropriate avenue for Rosario claims raised in a CPL 440.10 motion.
CPL 440.10(1)(f) requires a showing of prejudice; the improper conduct must have affected the trial and prejudiced the defendant. “To prevail under CPL 440.10 (1) (f), however, a defendant must do more than demonstrate that the conduct at issue was improper. The statute by its very terms affords a remedy only if the defendant’s trial was affected by conduct that was both improper and prejudicial.”
The per se error rule developed in Rosario cases on direct appeal was a policy decision, balancing defendant’s rights against society’s. However, CPL 440.10 requires a showing of prejudice, reflecting society’s interest in the finality of judgments.
The Court adopted a “reasonable possibility” standard for prejudice, requiring the defendant to show that the failure to disclose the Rosario material “contributed to the verdict.” This aligns with the standard in Rosario itself and with Brady claims where a specific request was made.
The Court emphasized that the per se error rule continues to apply to Rosario claims on direct appeal and when a Rosario claim is raised concurrently on direct appeal and in a CPL 440.10 motion (per People v. Novoa).
The Court rejected the dissent’s view that the procedural distinction was arbitrary, emphasizing that it was an effort to balance the rights of the defendant against the interests of society, particularly the interest in the finality of judgments, given the lack of a time limit on CPL 440.10 motions.
