The Neuwirth Law is a French law which lifted the ban on birth control methods on December 28, 1967, including oral contraception. It was passed by the National Assembly on December 19, 1967. The law is named after Lucien Neuwirth, the Gaullist politician who proposed it. It replaced a law from 1920 that not only forbade all forms of contraception, but also information about contraception. The law was not fully implemented until 1972 due to administrative delays.
