The Supreme Court has ruled that a Michigan defendant cannot be retried for arson even though his initial acquittal was based on a judge's mistake.
The court voted 8-1 Wednesday in favor of Lamar Evans, who was charged with arson after he was seen running away from a burning vacant house in Detroit with a gasoline can in his hand.
A judge acquitted Evans midway through his trial based on a mistaken interpretation of the law.
Justice Sonia Sotomayor said for the court that the acquittal is final, even if granted in error. Justice Samuel Alito dissented.
