Passage: Since the PLM Law of 1982, three French communes also have a special status in that they are further divided into municipal arrondissements: these are Paris, Marseille, and Lyon. The municipal arrondissement is the only administrative unit below the commune in the French Republic, but existing only in these three communes. These municipal arrondissements are not to be confused with the arrondissements that are subdivisions of French départements: French communes are considered legal entities, whereas municipal arrondissements, by contrast, have no official capacity and no budget of their own.

Question: Municipal arrondissements exist in what three communes?
Paris, Marseille, and Lyon
