Ed. Code, § 26702

(a) For the purpose of payments into or out of the fund for adjustments of errors or omissions with respect to the Cash Balance Benefit Program, the period of limitation shall be applied as follows:

(1) No action may be commenced by or against the board, the system, or the plan more than three years after all obligations to or on behalf of the participant or beneficiary have been discharged.

(2) In cases where the system makes an error resulting in incorrect payment to the participant or beneficiary, the system’s right to commence recovery shall expire three years from the date of payment.

(3) If an erroneous payment is made due to lack of information or inaccurate information regarding eligibility of a participant or beneficiary to receive a benefit from the Cash Balance Benefit Program, the period of limitation shall commence when the system discovers the erroneous payment.

(b) Notwithstanding any other provision of this section, if any erroneous payment has been made on the basis of fraud or intentional misrepresentation by a participant or beneficiary, or other party in relation to or on behalf of a participant or beneficiary, the three-year period of limitation shall not be deemed to commence or to have commenced until the system discovers the erroneous payment.
