—(1) A pension granted to an officer under this Act shall not exceed two-thirds of the highest pensionable emoluments drawn by him at any time in the course of his public service in Singapore.
(2) Where an officer has been or is granted a pension or pensions in respect of other public service, he may be granted the full pension for which he is eligible in respect of his public service in Singapore.
(3) No person may at any time draw from the Pension Fund an amount of pension which, when added to the amount of any pension or pensions drawn in respect of other public service, exceeds two-thirds of the highest pensionable emoluments drawn by that person at any time in the course of his public service in Singapore or in other public service.
(4) Where a person referred to in subsection (3) receives, in respect of some period of public service, both a gratuity and a pension, the amount of such pension shall be deemed, for the purpose of subsections (2) and (3), to be the amount of pension which would have been payable had the officer received a pension only and not a gratuity and a pension.
(5) In a case falling under subsection (3), the amount of pension to be drawn from the Pension Fund shall be subject to the approval of the relevant Pension Authority, in order that it may be determined with due regard to the amount of any pension or pensions similarly to be drawn in respect of other public service.
(6) For the purpose of this section, an allowance granted in respect of injury or disease shall not be taken into account; but where the officer is granted such an allowance, the amount of such allowance which he may draw shall not exceed one-sixth of his highest pensionable emoluments at any time in the course of his public service by more than the sum by which the amount of his pension or pensions, apart from such allowance, falls short of two-thirds of such highest pensionable emoluments.
