Overview

Washington's legal system is one of the most progressive in the nation, with comprehensive reforms in criminal justice, environmental regulation, worker protections, and civil rights. The state was one of the first two to legalize recreational marijuana (2012), has the highest state minimum wage ($16.28/hr), enacted an assault weapons ban, and has a cap-and-invest climate program.

Washington's legal framework includes strong tenant protections with just cause eviction, all-mail voting since 2011, comprehensive paid family and medical leave, and the nation's first long-term care insurance program. The state's tech industry (Amazon, Microsoft) creates significant legal activity in privacy, employment, and antitrust law.

Washington's court system includes municipal courts, district courts, superior courts (general jurisdiction trial courts in 39 counties), the Court of Appeals (three divisions), and the Washington Supreme Court. Superior court judges are elected in nonpartisan elections. Supreme Court justices are elected statewide for six-year terms.
