1.—(1) Where the surviving spouse would otherwise have been entitled to a special award under rule 2 of Part 2 or an augmented award under rule 3 of that Part, the amount of his pension under that Part shall, subject to sub-paragraph (2), be calculated in accordance with paragraph 1 of Part 1 of Schedule 3 to the Pension Scheme in the same way as that of an ordinary pension.
(2) For the purposes of this paragraph, paragraph 1 of Part 1 of Schedule 3 to the Pension Scheme has effect—
(a)as if the reference in sub-paragraph (1)(a) to the base pension were a reference to the appropriate proportion of the base pension; and
(b)as if the base pension were the ill-health pension to which the deceased would have been entitled if he had, when he ceased to serve, retired because he was disabled in circumstances entitling him to such a pension.
2. The appropriate proportion mentioned in paragraph 1(2)(a) is the proportion which the deceased’s relevant pensionable service bears to his total pensionable service.
