Gregg v. Georgia involved Troy Leon Gregg and Floyd Allen who were found guilty of armed robbery and murdering Fred Simmons and Bob Moore. Gregg was sentenced to death in Georgia which was upheld by the state Supreme Court. Gregg then appealed to the U.S. Supreme Court arguing his death sentence constituted cruel and unusual punishment under the Eighth and Fourteenth Amendments. The U.S. Supreme Court ruled 7-2 in favor of Georgia, establishing a precedent that reinforced the constitutionality of the death penalty.
