Washington Constitution Art. 4, § 3(a). Retirement of Supreme Court and Superior Court Judges

A judge of the supreme court or the superior court shall retire from judicial office at the end of the calendar year in which he attains the age of seventy-five years. The legislature may, from time to time, fix a lesser age for mandatory retirement, not earlier than the end of the calendar year in which any such judge attains the age of seventy years, as the legislature deems proper. This provision shall not affect the term to which any such judge shall have been elected or appointed prior to, or at the time of, approval and ratification of this provision. Notwithstanding the limitations of this section, the legislature may by general law authorize or require the retirement of judges for physical or mental disability, or any cause rendering judges incapable of performing their judicial duties.
