This Order modifies, by virtue of section 65 of the Social Security Act 1973, the pensions schemes for the holders of the offices listed in the Schedule to the Order so as to make the changes required in order to meet the contracting-out requirements laid down by the Social Security Pensions Act 1975. Articles 6 and 7 confer on an office holder and on his widow entitlement to pensions based on the final salary of the office holder and his years of service up to pensionable age (65 for men, 60 for women) and after 21st April 1978. The pensions are not to be less than the minimum guaranteed by Articles 8 and 9, and there will be occasions where the guaranteed minimum only will be payable (such as under Article 12). Article 10 provides the mode of ascertainment of final salary for the purposes of the Order, and Article 11 provides arrangements for the payment of contributions in respect of widows' pensions that may become payable by virtue of the Order where the office holder marries after retirement. The remaining Articles are explanatory and supplementary.
