Capital punishment was suspended in the United States from 1972 through 1976 primarily as a result of the Supreme Court's decision in Furman v. Georgia. The last pre-Furman execution was that of Luis Monge on June 2, 1967. In this case, the court found that the death penalty was being imposed in an unconstitutional manner, on the grounds of cruel and unusual punishment in violation of the Eighth Amendment to the United States Constitution. The Supreme Court has never ruled the death penalty to be per se unconstitutional.
In what year was the suspension of the death penalty in South America ended?
