3. These regulations shall apply to any person who—
(a)was employed immediately before the material date, either for the whole or for a part only of his time, as an officer of a local authority or under such an officer for the purposes of the functions of the local authority, or
(b)would have been so employed at that time but for any national service on which he was then engaged.
4. Subject to the provisions of these regulations, any person to whom these regulations apply and who suffers loss of employment or loss or diminution of emoluments which is attributable to an order made under section 17(1) of the Act or to anything done in pursuance of such order shall be entitled to have his case considered for the payment of compensation under these regulations, and such compensation shall be determined in accordance with these regulations.
5.—(1) Where any person to whom these regulations apply would have been employed immediately before the material date as an officer of a local authority or under such an officer for the purposes of the functions of the local authority but for any national service on which he was then engaged, then if before the expiry of 2 months after ceasing to be so engaged, or, if prevented by sickness or other reasonable cause, as soon as practicable thereafter, he gives notice to the compensating authority that he is available for employment, that person shall be entitled to have his case considered for the payment of compensation on the ground—
(a)if he is not given or offered re-employment in his former office or in any reasonably comparable office (whether in the same or in a different service), of loss of employment; or
(b)if he is so re-employed with diminished emoluments as compared with the emoluments which he would have enjoyed had he continued in his former employment, of diminution of emoluments.
(2) The loss of employment which is the cause of a claim for compensation under paragraph (1)(a) shall be treated as having occurred on the earlier of the two following dates, that is to say, the date of the refusal of re-employment or a date one month after the date on which the person gave notice that he was available for employment; and the person shall be deemed to have been entitled to the emoluments which he would have enjoyed at such earlier date had he continued in his former employment.
