Previous service reckonable without payment
9.—(1) Subject to paragraph (2), there shall be reckonable by a police officer as pensionable service—
(a)where he previously retired from the police service upon becoming entitled to a pension on the ground of disablement under regulation 18 and, following termination of that pension under regulation 48(5), (6), or (7), has rejoined the service, any period of pensionable service which was reckonable by him immediately before he so retired;
(b)where he previously ceased to serve as a police officer with an entitlement to a deferred pension which has not come into payment and has subsequently rejoined the service, any period of pensionable service reckonable by him immediately before he so ceased to serve;
(c)where he previously ceased to serve as a police officer with an entitlement to a deferred pension which, in accordance with regulation 29, came into payment early on the ground of permanent disablement for engaging in any regular employment and his pension has been terminated upon his rejoining the service under regulation 48(5), any period of pensionable service reckonable by him immediately before he so ceased to serve.
(2) Where a police officer to whom paragraph (1) applies was, during the period of pensionable service in question, purchasing added years by periodical contributions, those added years shall be taken into account only to the extent that—
(i)in a case falling within paragraph 1(a), they are reckonable by virtue of regulation 57(5), and
(ii)in a case falling within paragraph 1(b) they were taken into account for the purposes of entitlement to the deferred pension mentioned in sub-paragraph (b).
(3) In a case falling within paragraph (1)(b), the entitlement of the officer concerned to the said deferred pension shall accordingly be relinquished.
(4) This regulation has effect subject to regulation 11.
