15.—(1) Subject to paragraph (2), every member, associate or student of the Society shall, in addition to the fees payable on his registration in the appropriate register, pay to the Society in respect of each year such fee (a “retention fee”) as may be prescribed, in respect of the retention of his name in the appropriate register in that year.
(2) A retention fee shall not be payable by any person in respect of the year in which he first becomes a member or, as the case may be, an associate or student of the Society.
(3) If a person on whom a demand has been made in the prescribed manner for payment of a retention fee payable by him under this Article fails to pay the fee within two months after the date on which the demand therefor was made, the Council may direct the removal of his name from the appropriate register; but, if, either within the year in respect of which the fee is payable or within such longer period as the Council may allow, the person whose name has been removed from the register pays to the Society the retention fee, together with such additional sum (if any) by way of penalty for the default as may be prescribed, his name shall be restored to the appropriate register and, if the Council so directs, the restoration shall have effect as from the date on which his name was removed from that register.
(4) In this Article, “year” means a period of twelve months beginning on such date as the Council may determine or, where the Council varies that date, such period (whether greater or less than twelve months) immediately following the variation as the Council may determine.
(5) Nothing in this Article shall apply to honorary members of the Society.
