H.2. Abatement of pensions on re-employment: general rules
(1) If—
(a)the annual rate of the basic pay payable to the re-employed pensioner as at the last day of his old service (“the old rate”), exceeds the amount of the annual rate of the basic pay payable to him at the time he enters the new service (“the new rate”), and
(b)the annual rate of the old service pension to which he is entitled at the time of entering the new service or, if he is a deferred member, at the time when he becomes entitled to payment of the pension, is greater than the amount of that excess,
the annual rate of the old service pension as at that time is reduced by such amount (“the reduction amount”) as is necessary so that it is equal to the amount of that excess as at that time.
(2) If the new rate equals or exceeds the old rate, the re-employed pensioner is not entitled to payment of the old service pension during the new service.
(3) Where paragraph (1) applies, the annual rate of the old service pension continues to be reduced during the new service by the reduction amount regardless of any increase in the annual rate of the old service pension made after the time when the member is re-employed, or, if he is a deferred member, after the time he becomes entitled to payment of the pension.
(4) In the case of a re-employed pensioner who exercises the option under rule D.10 (option to exchange lump sum for pension) in relation to the old service pension, any increase of the pension as a result of the exercise of the option is disregarded for the purposes of this Part.
