2.—(1) Subject to the provisions of these Rules, where a person has been employed full time—
(a)by an Approved Society; or
(b)by some other body (including a body of which the Society is a branch or section) administering the affairs of an Approved Society; or
(c)by a body administering a special scheme under Section 73 of the Unemployment Insurance Act (which section relates to special schemes);
and, whether before or after the passing of the Act but before the 5th July, 1949, becomes a civil servant, then, if his employment by such Society or body was such as to satisfy the conditions provided in Rule 3, such employment shall be treated for the purposes of the Superannuation Acts in the manner provided by Rule 4 or, as the case may be, Rule 5.
(2) If a person who otherwise satisfies the provisions of the last preceding paragraph is unable to become a civil servant before the 5th July, 1949, by reason only of his failing on account of ill health or disablement to satisfy the Civil Service Commissioners, but commences to serve the State in an unestablished capacity before that date, and after continuous service in such a capacity becomes a civil servant at some later date, the Minister, with the consent of the Treasury, may direct that he shall be treated as having satisfied those provisions, and these Rules shall apply accordingly in his case but subject to such modifications as the Treasury may determine.
