14.—(1) If the claimant was a person in respect of whose service a widow's pension might have become payable under the pension scheme to which he was last subject before losing his employment, then, if he so desires and informs the compensating authority by notice in writing accordingly when making his claim, he may surrender so much of any annual sum which may become payable to him as compensation under paragraph 11 or 12 of this schedule as represents the annual value of the contingent right in respect of widow's pension, in consideration of the payment by the compensating authority to the person who as his widow might have become entitled to such widow's pension as aforesaid in the event of her surviving him—
(a)if he dies before attaining normal retiring age, and without having given a notice pursuant to the provisions of paragraph 11 of this schedule, of an annual sum equal to the amount of the pension to which she would have become entitled had he, immediately before he died, become entitled to a pension under the pension scheme on grounds of ill-health of an amount equal to the amount of his accrued incapacity pension, less the part thereof surrendered under the provisions of this paragraph and any part thereof surrendered under the provisions of paragraph 16; and
(b)if he dies on or after attaining normal retiring age, or after giving a notice pursuant to the provisions of paragraph 11 of this schedule, of an annual sum equal to the amount of the pension to which she would have become entitled in accordance with the method of calculation prescribed by the pension scheme had he, at the date on which he attained normal retiring age, or gave the said notice, become entitled to a pension under the pension scheme of an amount equal to the amount of his accrued pension or accrued incapacity pension, as the case may be, less the part thereof surrendered under the provisions of this paragraph and any part thereof surrendered under the provisions of paragraph 16.

(3) Any sum payable to a widow under this paragraph shall cease to be payable or shall be suspended in any circumstances in which a widow's pension under the aforesaid pension scheme would have ceased to be payable or would have been suspended.
