30.—(1) Except in relation to any accrued pension, accrued retiring allowance, accrued incapacity pension or accrued incapacity retiring allowance attributable to service as a contributory employee or local Act contributor, the provisions of Regulations 18, 19, 20 and 21 of these Regulations shall not apply to a person who had been participating in a scheme associated with his employment for providing superannuation benefits by means of contracts or policies of insurance, and who, after the loss of his employment or the diminution of his emoluments, continued to participate in that scheme, or became entitled to a benefit or prospective benefit thereunder other than a return of contributions.
(2) If the claimant is such a person as is mentioned in paragraph (1) of this Regulation who has lost his employment, the compensating authority may, if the relevant scheme so permits, make such payments to or in respect of him, whether by way of the payment of premiums or otherwise, as will secure that his benefits under the scheme are increased to an extent actuarially equivalent to that by which similar amounts of retirement compensation could be increased under Regulation 23(2) or (4) of these Regulations.
(3) If the claimant is such a person as is mentioned in paragraph (1) of this Regulation who has suffered a diminution of his emoluments, the compensating authority may, if the relevant scheme so permits, make such payments to or in respect of him, whether by way of the payment of premiums or otherwise, as will secure to the claimant the like benefits under the scheme as if his emoluments had not been diminished.
(4) If the claimant is such a person as aforesaid and he becomes entitled to a benefit under such a scheme as is mentioned in paragraph (1) of this Regulation before reaching normal retiring age, the compensating authority may reduce any long-term compensation payable to him under Part IV of these Regulations by the amount of such benefit.
