Referred to by a leading scholar as the July 2 Cases and elsewhere referred to by the lead case Gregg, the Supreme Court set forth the two main features that capital sentencing procedures must employ in order to comply with the Eighth Amendment ban on "cruel and unusual punishments". The decision essentially ended the de facto moratorium on the death penalty imposed by the Court in its 1972 decision in Furman v. Georgia 408 U.S. 238 (1972). </P> <P> All five cases share the same basic procedural history .
