People v. LaValle
People v. LaValle, 3 N.Y.3d 88 (2004), was a landmark decision by the New York Court of Appeals, the highest court in the U.S. state of New York, in which the court ruled that the state's death penalty statute was unconstitutional because of the statute's direction on how the jury was to be instructed in case of deadlock. New York has since been without the death penalty, as the law has not been amended.
Louisiana State Penitentiary
In 1972, in the US Supreme Court decision in "Furman v. Georgia", the court found application of the death penalty so arbitrary under existing state laws that it was unconstitutional. It suspended executions for all persons on death row in the United States (slightly more than 600, overwhelmingly male) under current state laws in the United States, and ordered state courts to judicially amend their sentences to the next lower level of severity, generally life in prison. Louisiana passed a new death penalty statute, which was overturned by the state supreme court in 1977 for its application to convictions for rape. The death penalty statute was amended again, effective September 1977. Louisiana did not execute any prisoners until 1983.
