Napoleon's set of civil laws, the Code Civil—now often known as the Napoleonic Code—was prepared by committees of legal experts under the supervision of Jean Jacques Régis de Cambacérès, the Second Consul. Napoleon participated actively in the sessions of the Council of State that revised the drafts. The development of the code was a fundamental change in the nature of the civil law legal system with its stress on clearly written and accessible law. Other codes ("Les cinq codes") were commissioned by Napoleon to codify criminal and commerce law; a Code of Criminal Instruction was published, which enacted rules of due process.
