Missouri overrules the United States Supreme Court on capital punishment for minors.

Under the U.S. Supreme Court's 1989 decision in Stanford v. Kentucky, the Eighth Amendment's cruel and unusual punishments clause does not shield minors 16 or 17 years of age from the death penalty. Holding, astonishingly, that Stanford is no longer the law of the land, the Missouri Supreme Court recently reversed the death sentence of a 17-year-old murderer in Simmons v. Roper. The U.S. Supreme Court has granted certiorari to consider whether Stanford survives its own burial by the state court.
