French Constitutional Law of 1940

French Constitutional Law of 1940, are the bills that were voted into law on 10 July 1940 by the National Assembly, which comprised both the Senate and the Chamber of Deputies during the French Third Republic. The law established the regime of Vichy France. It passed with 569 votes to 80, with 20 abstentions. The group of 80 parliamentarians who voted against it are known as the Vichy 80. The law gave all the government powers to Philippe Pétain, and further authorized him to take all necessary measures to write a new constitution. Pétain interpreted this as de facto suspending the French Constitutional Laws of 1875 which established the Third Republic, even though the law did not explicitly suspend it, but only granted him the power to write a new constitution. The next day, by Act No 2, Pétain defined his powers and abrogated all the laws of the Third Republic that were incompatible with them.

Constitutional Law of 1940 was annulled with the law of 9 August 1944 that declared it null and void and proclaimed that the republic never ceased to exist.
