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.
Alfred P. Southwick
After a series of botched hangings in the United States there was mounting criticism of this form of capital punishment and the death penalty in general. In 1886 newly elected New York State governor David B. Hill set up a three-member death penalty commission to find a more humane form of execution. The committee included Southwick, human rights advocate and reformer Elbridge Thomas Gerry, and New York lawyer and politician Matthew Hale. They explored many forms of execution and in 1888 recommended electrocution using Southwick's electric chair idea with metal conductors attached to the condemned person's head and feet. Based on their advice the first law allowing the use of electrocution went into effect in New York State on January 1, 1889. Development of Southwicks idea into a working device was turned over to the New York Medico-Legal Society.
