54. For paragraph (6) of regulation 78 (Part-time employment) substitute—
“(6) If a member with superannuable service in part-time employment becomes entitled to a pension under regulation 13, 13A, 14 or 14A (ill health pensions, pensions on redundancy and early retirement pensions)—
(a)the member’s superannuable service in part-time employment will count at its full length for the purpose of calculating—
(i)whether and (if so) to what extent, the superannuable service upon which the pension under regulation 13 or 13A is based should be increased under that regulation; or
(ii)the qualifying service for the purposes of regulation 14(2)(a) or regulation 14A(2)(a),
(b)the pension will be based on the whole-time equivalent of the period of part-time employment and, in the case of a pension under regulation 13 or 13A, the increase under that regulation will be limited to such amount as bears the same proportion to the amount that would have been paid had the superannuable service not been part-time as the whole-time equivalent bears to comparable whole-time employment.”.
