Notwithstanding the provisions of section 9 of the Health and Medicines Act 1988( ) (revocation of regulation 75 of the Superannuation Regulations( ) and consequent reduction of pension on re-employment as a practitioner after attaining the age of 65 years), where at any time in the period beginning on 1st March 1990 and ending on 31st March 1990—
(a) a practitioner between the ages of 65 and 70 years, who became entitled to a pension as a practitioner on or after attaining the age of 65 years, was engaged in further employment as a practitioner, and
(b) regulation 75 of the Superannuation Regulations operated in his case with the result that such further employment was disregarded for the purpose of determining whether the pension payable to him under the Superannuation Regulations should be reduced,
any further employment, between the ages of 65 and 70 years, by that practitioner shall continue to be disregarded as if regulation 75 had not been revoked.
