RAP 13.1: METHOD OF SEEKING REVIEW
(a) One Method of Seeking Review. The only method of seeking review by the Supreme Court of decisions of the Court of Appeals is review by permission of the Supreme Court, called "discretionary review."
(b) Writ Procedure Superseded. The procedure for seeking review of decisions of the Court of Appeals established by these rules supersedes the review procedure formerly available by extraordinary writs of review, certiorari, mandamus, prohibition, and other writs formerly considered necessary and proper to the complete exercise of appellate and revisory jurisdiction of the Supreme Court.
