After the
February Revolution of 1848 Chadenet was elected to represent Meuse in the Constituent Assembly. Chadenet was Representative of Meuse from 23 April 1848 to 26 May 1849. He joined the Right majority, and was a member of the Committee on Departmental and Communal Administration. He voted for restoration of physical constraint, for the prosecution of
Louis Blanc and
Marc Caussidière, for the state of siege, against abolition of the death penalty, against the
Jules Grévy amendment, against the right to work and against reduction of the salt tax. Chadenet fully supported
Louis-Napoleon Bonaparte after his election as President of France in December 1848. Chadenet was absent during the 12 January 1849 vote on the
Rateau proposal to bring the operation of the Constituent Assembly to an end, but a ballot paper with his name was found in the ballot box. He wrote to the editor of the official
Moniteur saying that he had been sick at home on 12 January, but the ballot paper perfectly expressed his will. Chadenet was reelected Representative of Meuse in the National Legislative Assembly on 13 May 1849, and again sat with the Right group. He continued to give his full support to Bonaparte. He voted with the leaders of the Right, and voted for the law of 31 May restricting universal suffrage. When a struggle began between the president and the royalist majority he confirmed his support for Bonaparte. He held office until the
coup d'état of 2 December 1851. ==Second Empire (1851–70)==
