Substantive law is the set of laws that governs how members of a society are to behave. It is contrasted with procedural law, which is the set of procedures for making, administering, and enforcing substantive law. Substantive law defines rights and responsibilities in civil law, and crimes and punishments in criminal law. It may be codified in statutes or exist through precedent in common law.
