Capital punishment in France (peine de mort en France) is banned by Article 66-1 of the Constitution of the French Republic, voted as a constitutional amendment by the Congress of the French Parliament on 19 February 2007 and simply stating "No one can be sentenced to the death penalty" (Nul ne peut être condamné à la peine de mort). The death penalty was already declared illegal on 9 October 1981 when President François Mitterrand signed a law prohibiting the judicial system from using it and commuting the sentences of the seven people on death row to life imprisonment. The last execution took place by guillotine, being the main legal method since the French Revolution; Hamida Djandoubi, a Tunisian citizen convicted of torture and murder on French soil, who was put to death in September 1977 in Marseille. Major French death penalty abolitionists across time have included philosopher Voltaire; poet Victor Hugo; politicians Léon Gambetta, Jean Jaurès and Aristide Briand; and writers Alphonse de Lamartine and Albert Camus. Prior to 1791, under the Ancien Régime, there existed a variety of means of capital punishment in France, depending on the crime and the status of the condemned person: Hanging was the most common punishment. Decapitation by sword, for nobles only. Burning for arson, bestiality, heresy, sodomy, and witchcraft. The convict was occasionally discreetly strangled. Breaking wheel for brigandage and murder. The convict could be strangled before having his limbs broken or after, depending on the atrocity of his crime. Death by boiling for counterfeiting. Dismemberment for high treason, parricide, and regicide. On 6 July 1750, Jean Diot and Bruno Lenoir were strangled and burned at the stake in Place de Grève for sodomy, the last known execution for sodomy in France. Also in 1750, Jacques Ferron was either hanged or burned at the stake in Vanvres for bestiality, the last known execution for bestiality in France. The first campaign towards the abolition of the death penalty began on 30 May 1791, but on 6 October that year the National Assembly refused to pass a law abolishing the death penalty.
