The legal system of Monaco

A French-influenced civil-law microstate where sovereignty rests with the Prince, who delegates judicial power to the courts in his name. Codes closely track the French model, and senior judges are frequently French magistrates, but Monaco is an independent state and not part of France. It uses the euro under a monetary agreement without being an EU member.
