There are four types of law. Constitutional, Statutory, Administrative, and Judicial. Constitutional law was made by the originators and can be further made by ammendments. Statutory law is made by legislatures. Administrative law is made by the various agencies (their regulations). Judicial law is made by the Court. Constitutional law has itself as authority (in truth it is the People that give it authority), Statutory and Judicial are given authority by the Constitution, and Administrative law gets authority from the Executive and legislative functions of government. All forms of law are law.
