V1.—(1) This regulation applies in relation to any pension which is payable under these Regulations to or in respect of a person who, having served in an employment or office, service in which qualified persons to participate in the benefits provided under the previous regulations, ceased to serve therein or died before these Regulations came into force.
(2) Where, in a case to which this regulation applies, any provision of these Regulations would operate in relation to any person so as to place that person in a worse position than he would have been if the provision had not applied, that person may elect that the provision shall not so apply by giving notice in accordance with paragraph (3).
(3) A notice given pursuant to paragraph (2) shall be in writing and shall be delivered to the Secretary of State within 6 months of the coming into force of these Regulations.
(4) An election pursuant to paragraph (2) shall have effect in relation to the pension referred to in paragraph (1) only to the extent that such pension has accrued by virtue of contributions made and periods of service rendered prior to the cessation referred to in paragraph (1) (or, if there has been more than one such cessation, the last of them before the coming into force of these Regulations) and in determining entitlement to, and the amount of, the pension to that extent, such person shall be treated as if he had never recommenced pensionable employment at any time after that cessation (or, as the case may be, the last such cessation).
