Career
Early years
Revolution
In November 1793, after the First French Republic had been proclaimed, he came to Paris and was thrown into prison for being the brother-in-law of Joseph Jérôme Siméon, the leader of the Federalists in Provence. He was soon released to a maison de santé, where he remained until the fall of Maximilien Robespierre during the Thermidorian Reaction. On being released he practised as a lawyer in Paris, and, in 1795, he was elected by the capital to the Council of Ancients of the French Directory, becoming a leader of the moderate party opposed to the directory rule.
As a leader of the moderates, he was targeted by the coup d"état of 18 Fructidor, but, unlike General Charles Pichegru and François Barbé-Marbois, he managed to escape to Switzerland, then to Holstein, and did not return until after Napoleon Bonaparte established himself as the leader of the new Consulate.
Under Napoleon
Bonaparte made him a conseiller d"état in 1800, and then charged him, with François Denis Tronchet, Félix-Julien-Jean Bigot de Préameneu, and Jacques de Maleville, to draw up the Code Civil. Of this commission he was the most notable member, and many of the most important titles, notably those on marriage and heirship, are his work.
He did a famous speech, "Discours préliminaire au projet de code civil" in which he presents the core principles of the civil code: legal certainty (non-retroactivity), the notion of "ordre public" and the forbidding of the "arrêt de règlement" which was a characteristic production of the Ancien Régime"s judges and was contrary to the idea that only the law prevails. In 1801 he was placed in charge of the Department of Religion or Public Worship, and in that capacity had the chief share in drawing up the provisions of the Concordat of 1801.
He soon after became totally blind, and, after an operation, he died at Paris.
