28. A police officer’s enhanced top-up ill-health pension shall be—
(a)an annual sum payable for life and;
(b)a lump-sum payment.
(2) The amount in paragraph (1) shall be calculated by deducting the annual sum and lump-sum payment payable as his standard ill-health pension from the annual sum and lump-sum respectively as calculated in accordance with paragraphs (2) — (6) (“enhanced top-up totals”).
(3) A police officer’s enhanced top-up totals shall be calculated in accordance with regulation 25 as if he had been entitled to an ordinary pension at the date of his retirement, but for the purposes of that calculation the pensionable service the officer concerned is entitled to reckon at the date of his retirement shall be treated as having been increased in accordance with the provisions of paragraph (4) or (5), subject to paragraph (7) as the case may require.
(4) In the case of an officer entitled to reckon less than five years' pensionable service as at the date of his retirement, either—
(a)the period of his pensionable service shall be multiplied by four, or
(b)there shall be added to that service a period equivalent to half of the pensionable service he would have become entitled to reckon in respect of the period beginning with the date of the officer’s retirement and ending on the day immediately before that on which he would attain the age of 55 years, had he continued to serve and to pay pensions contributions in accordance with regulation 5 (“prospective service”), whichever amounts to the lesser period.
(5) In the case of an officer entitled to reckon five or more years' pensionable service as at the date of his retirement, there shall be added to that service a period equivalent to half of his prospective service.
(6) In the case of an officer who has spent one or more periods in part-time service as such in determining the number of years of pensionable service that he is entitled to reckon as at the date of his retirement for the purposes of paragraphs (4) and (5), a period of service by virtue of which his pensionable service is reckonable as if it were a period of full-time service (but this paragraph does not apply so as to affect any other references to pensionable service in paragraphs (4), (5) and (7)).
(7) In the case of an officer who has spent one or more periods in part-time service as such, the period of prospective service for the purposes of paragraph (4)(b) or (5), as the case may be, shall be calculated as if, during the period beginning with the date of the officer’s retirement and ending on the day immediately before that on which he would attain the age of 55 years, he would have served part-time for the same proportion of that period as his total pensionable service before his retirement bears to the total pensionable service he would have been entitled to reckon before his retirement if all that service had been full-time.
(8) If in a case where any of the officer’s service by virtue of which his pensionable service is reckonable was part-time service, the amount of the pension calculated in accordance with the preceding paragraphs would be less than it would have been if he had become entitled to receive the pension at an earlier date, then the pension shall be of that amount instead.
