30 Person may be treated as having been retired on ground of invalidity

(1) Where a person has been retired otherwise than on the ground of invalidity but, after his or her retirement, CSC is satisfied that, at the time the person was retired, grounds existed on which he or she could have been retired on the ground of invalidity, CSC may, for the purposes of these Rules, treat the person as if he or she had been retired on the last‑mentioned ground. (2) Where, because of action taken under subrule (1), a person is classified as Class A or Class B under rule 22 or has an interim classification made under rule 22A: (a) so much of the preserved benefit applicable to him or her under rule 12, 13 or 14 as consists of employer benefit ceases to be applicable to him or her; and (b) a pension is payable to him or her in accordance with rule 27 or 28, as the case may be. (3) This rule does not apply to a person to whom a preserved employer benefit is not applicable.
