Furman v. Georgia, 408 U.S. 238 (1972), was a landmark criminal case in which the United States Supreme Court decided that arbitrary and inconsistent imposition of the death penalty violates the Eighth and Fourteenth Amendments, and constitutes cruel and unusual punishment. It was a per curiam decision. Five justices each wrote separately in support of the decision. Although the justices did not rule that the death penalty was unconstitutional, the Furman decision invalidated the death sentences of nearly 700 people. The decision mandated a degree of consistency in the application of the death penalty. This case resulted in a de facto moratorium of capital punishment throughout the United States. Dozens of states rewrote their death penalty laws, most of which were upheld in the 1976 case Gregg v. Georgia.
