Office-holders to whom Order applies
4. This Order shall have effect in relation to, but only to, an office-holder who is holding a scheduled office on 1st September 1988, or who is appointed to such an office when under pensionable age on or after that date:—
Provided that neither article 6 nor article 7 shall entitle an office-holder appointed to a scheduled office on or after 1st April 1987, or his widow, to a pension other than the minimum guaranteed under article 8 or article 9, unless his service in that office may be reckoned, for the purpose of superannuation benefits, together with service of his in an earlier office wholly or partly before that date (or might have been so reckoned but for his having left the later office before reaching compulsory retirement age).
