23.—(1) The compensation awarded to a whole-time officer for diminution of emoluments shall be awarded by way of an annual sum, payable for the same period or periods as would be the case were he a whole-time officer claiming compensation for loss of office under Parts II and III of this Schedule, and shall not, in respect of any such period, exceed a sum bearing the same proportion to the maximum amount of compensation which could have been awarded had he lost office as the annual rate of his emoluments immediately after diminution bears to the annual rate of his emoluments immediately before diminution:
(2) Any reference in the foregoing provisions of these Regulations to loss of office shall, in their application to a claim for diminution of emoluments, be construed as a reference to diminution of emoluments.
(3) Compensation under this Part of this Schedule shall cease to be payable if the whole-time officer ceases to hold the office in respect of which he is receiving compensation, otherwise than on grounds of ill health, injury or infirmity or of loss of office, before attaining normal retiring age.
