This section applies to every retiree who dies after this section becomes operative whether retired before or after the operative date of this section.

The total of the death benefits paid pursuant to Section 31789 and this section shall not exceed one thousand dollars ($1,000). The death benefits payable pursuant to Section 31789 and this section shall be paid only by the system which is subject to Section 31789 and this section and in which the member rendered his or her last service.
