(1) An application for disability retirement is filed on a properly executed form prescribed by the system.
(2) The effective date is later than the last day of creditable service for which compensation is payable to the member.
(3) The effective date is no earlier than either the first day of the month in which the application is received at the system's headquarters office or the date upon and continuously after which the member is determined to the satisfaction of the board to have been mentally incompetent.
(4) The application for disability retirement contains an election of either an unmodified allowance or an allowance modified under an option as provided in Section 24332.
