Law of Washington

The law of Washington consists of several levels, including constitutional, statutory, regulatory and case law, as well as local ordinances. The Revised Code of Washington forms the general statutory law.

The Constitution of Washington is the foremost source of state law. Legislation is enacted by the Washington State Legislature, published in the Laws of Washington, and codified in the Revised Code of Washington. State agency regulations (sometimes called administrative law) are published in the Washington State Register and codified in the Washington Administrative Code. Washington's legal system is based on common law, which is interpreted by case law through the decisions of the Supreme Court and Court of Appeals, which are published in the Washington Reports and Washington Appellate Reports, respectively. Counties, cities, and towns may also promulgate local ordinances.

The foremost source of state law is the Constitution of Washington. The Washington Constitution in turn is subordinate to the Constitution of the United States, which is the supreme law of the land.

Pursuant to the state constitution, the Washington State Legislature has enacted legislation. Its session laws are published in the Laws of Washington, which in turn have been codified, compiled, and/or consolidated in the Revised Code of Washington (RCW). Both are published by the Washington State Statute Law Committee and the Washington State Code Reviser which it employs and supervises.
