(a) Notwithstanding any other provision of this chapter, if a retired member elects to have his or her retirement allowance reduced pursuant to Section 31764.6 and if, thereafter, the member’s spouse predeceases the member, the member’s allowance shall be adjusted to the amount he or she received at retirement, adjusted by any cost-of-living increases that were or would have been added to the monthly allowance.
