Can a conviction be thrown out because the prosecution hid evidence? In Pennsylvania, the answer is yes. In Commonwealth v. Reyes-Acosta (2023), the Superior Court reversed a man’s conviction for indecent assault and ordered a new trial after finding that prosecutors failed to disclose important evidence to the defense. This kind of violation is known as a Brady violation—when the prosecution withholds evidence that could be favorable to the accused. The Reyes-Acosta case is a clear example of why the government must turn over all material evidence, and how a failure to do so can undo a verdict.

What Happened in the Reyes-Acosta Case?

Mr. Reyes-Acosta was convicted by a York County jury of indecent assault and harassment stemming from an incident with a woman who worked at his apartment complex. After the trial was over—in fact, not until after sentencing—the defense learned about a letter that had never been given to them before the trial. This letter, from the victim’s workers’ compensation insurer, showed that the victim received a payment of about $28,000 related to the incident. This was significant information: the defense could have used it during the trial to question the victim’s credibility or suggest she had a financial motivation to accuse Mr. Reyes-Acosta. However, because the prosecution only handed over the letter post-trial, the defense never got that chance.

Reyes-Acosta’s attorney filed a motion and appealed on the basis that the prosecution’s failure to provide this letter beforehand was a Brady violation. Under the Brady v. Maryland rule, the prosecution must disclose any evidence that is favorable to the defense if it is material to guilt or punishment. “Favorable” can mean it helps prove the defendant’s innocence or could be used to impeach (challenge) a witness’s credibility. In this case, the workers’ comp letter was clearly favorable impeachment evidence—it could cast doubt on the accuser’s motives. It was also material, meaning there is a reasonable chance the result of the trial could have been different if the jury knew about this payoff.

Superior Court: Withholding This Evidence Violated the Defendant’s Rights

The Pennsylvania Superior Court agreed that the prosecution should have disclosed the letter and that not doing so undermined the fairness of the trial. The court noted that the letter was in the possession of the District Attorney’s Office before the trial, so the defense had no way to know about it on their own. Because the letter showed the complainant received a substantial financial benefit, it was exactly the type of information that could make jurors question her testimony. The Superior Court ruled that by suppressing this evidence, the prosecution violated Mr. Reyes-Acosta’s due process rights. Consequently, the court vacated his conviction and remanded the case for a new trial. (Superior Court opinion)

This outcome doesn’t mean Mr. Reyes-Acosta is automatically innocent, but it does mean he gets another chance at trial where the defense can fully use all relevant evidence, including that letter, to defend him. It’s a strong reminder that fairness in a trial is paramount—when the government fails to play by the rules, a conviction cannot be allowed to stand.
