Herrera v. Collins, 506 U.S. 390 (1993), was a case in which the Supreme Court of the United States ruled by 6 votes to 3 that a claim of actual innocence does not entitle a petitioner to federal habeas corpus relief by way of the Eighth Amendment's ban on cruel and unusual punishment.

Or, as the Onion has put it, "Supreme Court Overturns Right v. Wrong."
