If you are a justice of the Washington supreme court or a judge in the court of appeals, superior court, district court, or municipal court and are an eligible member of the public employees' retirement system Plans 1, 2, or 3, you may purchase an increase on the benefit multiplier on past judicial service credit earned before becoming a judicial benefit multiplier (JBM) program member.
