The sources of the data for the Washington State Supreme and Appellate Court Decisions are the bound volumes of decisions for those issued before 1994, the advance sheets for those through June 2005, and slip opinions thereafter.

Although we strive for accuracy, the data does not absolutely mirror the report of the opinions in the official reports of the opinions of the Washington Supreme Court and Court of Appeals. All data on this site should be checked against the official reports, which can be found at all county law libraries in the state of Washington.

The website includes Court of Appeals unpublished opinions filed since July 2004. The unpublished opinions are preceded by the warning "DO NOT CITE." Unpublished opinions should not be relied on as precedent in any materials provided to courts. Read about the details.
