Cal. Gov't Code § 6508.2

(a)
1. (1) Prior to filing a notice of termination pursuant to Section 20570 or 20571, or a decision by the governing body of an agency that does not contract with the California Public Employees’ Retirement System to dissolve or to cease the operations of the agency, member agencies of an agency established by agreement under this chapter that participates in, or contracts with, a public retirement system, shall mutually agree as to the apportionment of the agency’s retirement obligations among themselves, provided that the agreement equals 100 percent of the retirement liability of the agency. A copy of this mutual agreement, signed by all parties thereto, shall be provided to the board, which shall be reflected in the agreement with the board. If the member agencies are unable to mutually agree, the board shall apportion the retirement liability of the agency to each member agency based on the share of service received from the agency, or population of each member agency, such that the apportionment equals 100 percent of the retirement liability of the agency, which shall be reflected in the agreement with the board.
2. (2) A member agency may challenge the determination by the board to apportion the retirement liability of the agency within 30 calendar days of the determination. However, a member, or a former member, that is not identified by the board pursuant to subdivision (a) shall not be permitted to challenge a determination by the board.
  1. (A) A challenge pursuant to this paragraph shall be referred by the member agency or agencies that challenge a determination by the board to an arbitrator who shall, at the arbitrator’s discretion, apportion the liability among the current and former member agencies such that the apportionment equals 100 percent of the retirement liability of the agency. The arbitrator shall make a decision as to the apportionment of liability no later than 60 calendar days following referral of a challenge.
  2. (B) The final decision by the arbitrator shall be binding on all current and former member agencies, and all costs of arbitration shall be equally shared among the member agencies that are identified by the arbitrator to share in the apportioned liability. The arbitrator shall submit an official copy of their final decision to the board within seven calendar days of the decision.
(b) An agency shall not be permitted to terminate pursuant to Section 20570 or 20571, nor shall a decision by the governing body of an agency that does not contract with the California Public Employees’ Retirement System to dissolve or cease to operate, become effective until a final determination or decision, pursuant to paragraph (1) or paragraph (2) of subdivision (a), is final.
(c) Upon notice by the board of a potential termination pursuant to Section 20572, an agency established by agreement under this chapter shall, within 60 calendar days, provide to the board a copy of an agreement, signed by all parties thereto, that sets forth the apportionment of 100 percent of the retirement obligations of the agency. If the agency does not timely provide a copy of the mutual agreement, the board shall in its sole discretion apportion the retirement liability of the agency among the current or former member agencies, such that the apportionment equals 100 percent of the retirement liability of the agency.
1. (1) A member agency may challenge the determination by the board to apportion the retirement liability of the agency within 30 calendar days of the determination. However, a member, or a former member, that is not identified by the board pursuant to subdivision (a) shall not be permitted to challenge a determination by the board.
2. (2) A challenge pursuant to paragraph (1) shall be referred by the member agency or agencies that challenge a determination by the board to an arbitrator who shall, at the arbitrator’s discretion, apportion the liability among the current and former member agencies such that the apportionment equals 100 percent of the retirement liability of the agency.
3. (3) The arbitrator shall make a decision as to the apportionment of liability no later than 60 calendar days following referral of a challenge and shall submit an official copy of their final decision to the board within seven calendar days of the decision. The final decision by the arbitrator shall be binding on all current and former member agencies, and all costs of arbitration shall be equally shared among the member agencies that are identified by the arbitrator to share in the apportioned liability. The board may take action to terminate the agency’s contract no earlier than 30 calendar days following the final decision by the arbitrator.
(d) Mutual agreement among the member agencies, or a determination by the board, as to the apportionment of the retirement liability of the agency pursuant to paragraph (1) of subdivision (a), or a decision by the arbitrator pursuant to paragraph (2) of subdivision (a), may include the apportionment of retirement liability to a former member of the agency.
(e) This section shall apply retroactively to current and former member agencies of an agency that has an agreement in existence with the board as of January 1, 2019. In addition, this section shall apply to a new agreement between an agency and the board on or after January 1, 2019. However, this section shall not apply to an agency established pursuant to this chapter that has dissolved prior to January 1, 2019.
(f) For purposes of this section, “board” means the board of any pension or retirement system of a public employer, including, but not limited to, an independent retirement plan offered by a public employer that the public employer participates in or offers to its employees for the purpose of providing retirement benefits, or a system of benefits for public employees that is governed by Section 401(a) of Title 26 of the United States Code.
(g) Notwithstanding any other law, if a judgment is rendered against an agency or a party to the agreement for a breach to its obligations to the public retirement system, the time within which a claim for injury may be presented or an action commenced against any other party that is subject to the liability determined by the judgment begins to run when the judgment is rendered.
