The law of New York consists of several levels, including constitutional, statutory, regulatory and case law, and also includes local laws, ordinances, and regulations. The Consolidated Laws form the general statutory law.
The Constitution of New York is the foremost source of state law. The legislation of the Legislature is published in the official Laws of New York and codified in the Consolidated Laws of New York. State agency rules and regulations are promulgated in the New York State Register and codified in the New York Codes, Rules and Regulations. Because New York is a common law state, every opinion, memorandum, and motion sent by the New York Court of Appeals (New York's highest court) and the Appellate Division of the New York Supreme Court (an intermediate appeals court) is published. Each local government may also adopt local laws, and counties, cities, and towns may promulgate ordinances to the extent authorized by state law, e.g. the New York City Administrative Code.
