(1A) Where a period would be a period of effective service in relation to a person by virtue of section 63 or 64 if the person were to make an election under subsection 63(1) or 64(1), as the case requires, and comply with subsection 63(2) or 64(2), as the case requires, subsection (1) of this section does not apply in relation to the period unless the period is also a period of effective service in relation to the person by virtue of section 63 or 64. (2) Where deferred benefits are applicable in respect of a person under section 82ZB of the previous Act but, before those benefits become payable, he became or becomes an eligible member of the Defence Force and those benefits cease to be applicable to him by virtue of section 82ZG of the previous Act, such period as CSC determines in relation to his service before 1 October 1972 shall be deemed to be a period of effective service in relation to him.
