Cal. Gov. Code § 9356.5
Any member whose service is discontinued but whose membership is continued under Section 9355.2 and who becomes a member of the Judges' Retirement System or is entitled to benefits under the Judges' Retirement Law, may elect to transfer all or part of the service for which he or she is credited under this system to the Judges' Retirement System pursuant to Section 75030.5. The election may be made at any time prior to retirement by written notice to the board of administration. The member shall designate in the notice the dates of the service that he or she elects to transfer. Upon receipt of the notice by the board of administration, the member's accumulated contributions on account of the period of service transferred, and the interest thereon, shall be transferred to the Judges' Retirement Fund.
If the member elects to transfer all of the service for which he or she is credited in this system, his or her membership in this system is terminated. If he or she elects to transfer less than all of the service for which the member is credited in this system, his or her membership is continued under Section 9355.2 and the service with which he or she is credited in this system is reduced by the amount so transferred.
Any member whose service is discontinued but whose membership is continued under Section 9355.2 who is entitled to receive credit under this system by making an election to do so and making a contribution to this system for the service, but who has not made the election, may, after becoming a member of the Judges' Retirement System, elect to receive credit for all or part of that service in the Judges' Retirement System pursuant to Section 75030.5. Upon making the election, the member may not thereafter elect to be credited in this system with the service so transferred.
This section does not apply to any person who, on or after January 1, 1986, first becomes or continues as a legislator, as defined in Section 9351.3, in a term of office that commences on or after January 1, 1986.
