The Constitution of Monaco, first adopted in 1911 after the Monégasque Revolution and heavily revised by Prince Rainier III on 17 December 1962, outlines three branches of government, including several administrative offices and a number of councils, who share advisory and legislative power with the prince.
The principality's local affairs (i.e., the administration of the four quarters of Monaco-Ville, La Condamine, Monte Carlo, and Fontvieille) are directed by the Communal Council, which consists of fifteen elected members and is presided over by the mayor.
Under the 1962 constitution, the prince shares his power with the unicameral National Council, the Principality's legislative body.
Though it is independent of the prince and may act contrary to his wishes, his signature is required to confirm any of its proposed laws.
The Supreme Court of Monaco is composed of five chief members and two assistant judges named by the prince on the basis of nominations by the National Council and other government bodies.
