Bird's-eye View Of Paris, France

France's highest courts are located in Paris. The Court of Cassation, the highest court in the judicial order, which reviews criminal and civil cases, is located in the Palais de Justice on the Île de la Cité, while the Conseil d'État, which provides legal advice to the executive and acts as the highest court in the administrative order, judging litigation against public bodies, is located in the Palais Royal in the 1st arrondissement.
The Constitutional Council, an advisory body with ultimate authority on the constitutionality of laws and government decrees, also meets in the Palais Royal.
• City government
Paris has been a commune (municipality) since 1834 (and also briefly between 1790 and 1795). At the 1790 division (during the French Revolution) of France into communes, and again in 1834, Paris was a city only half its modern size, but, in 1860, it annexed bordering communes, some entirely, to create the new administrative map of twenty municipal arrondissements the city still has today. These municipal subdivisions describe a clockwise spiral outward from its most central, the 1st arrondissement.
