(a) if the pension is suspended under subsection 74(3)--deferred benefits do not again become applicable in relation to the person because only of the suspension of the pension;
(aa) if the person's entitlement to the pension is cancelled under section 74A--deferred benefits again become applicable in relation to the person; and
(b) section 75 does not apply in relation to the person but subsection (2) of this section has effect in relation to him or her.
(2) Subject to subsection (3), if CSC is satisfied that the health of the person has become so restored as to enable him or her to perform duties of a kind that are, in the opinion of CSC, suitable to be performed by him or her (having regard to the duties performed by him or her immediately before he or she ceased to be an eligible employee, the duties performed by him or her in employment (if any) in which he or she was employed after he or she ceased to be such an employee and such other matters (if any) as CSC considers relevant), CSC may cancel the person's entitlement to pension but, upon the cancellation, the deferred benefits again become applicable in respect of the person.
(3) CSC shall not, under subsection (2) of this section, cancel a person's entitlement to pension at a time when pension would have become payable, apart from the operation of paragraph 138(2)(a).
