In a significant ruling for Texas criminal practice, the Texas Court of Criminal Appeals reportedly vacated the rape convictions of three men and held they are entitled to a new trial because prosecutors allowed false testimony from the accuser to be presented. As flagged in Law360’s appellate coverage, the decision was divided — a reminder that even where appellate courts agree a trial was flawed, the path to relief can turn on contested views of materiality, prosecutorial knowledge, and prejudice.

The legal principle at the center of the ruling is a familiar but powerful one: the state cannot secure or preserve a conviction through testimony it knows, or should know, is false.

A Pennsylvania federal judge has taken the unusual step of urging an investigation into Philadelphia District Attorney Larry Krasner’s office over its handling of a man’s yearslong attempt to overturn a murder conviction. The development stands out because the court’s concern is not limited to the integrity of the conviction itself; it extends to whether prosecutors or officials in a major urban DA’s office may have engaged in conduct warranting criminal scrutiny.

That distinction matters.
