s 15 Variation and revocation of orders
(1) Any order made under section 14 may be varied or revoked by the Land Administrator by writing under his hand: Provided that— (i) no such order or part thereof made with the sanction of the State Secretary shall be varied or revoked save with the sanction of the State Secretary; (ii) no such order shall be varied so as to prohibit or require anything not authorized by section 14 to be prohibited or required; (iii) the sanction of the State Secretary shall be required for any variation of such an order which, if contained in an original order under section 14, would require the sanction of the State Secretary; (iv) no such order shall, except with the express consent of the owner or occupier of the land in respect whereof the order was made, or of some person duly empowered so to consent on behalf of the owner or occupier, be varied unless reasonable opportunity shall first have been given to such owner or occupier to show cause why the order should not be varied. (2) Such notice shall refer to the subsisting order and to the date whereon the same was made and shall contain particulars of the manner in which the same is proposed to be varied. (3) After service of such notice the procedure prescribed by sections 12 and 13 shall, subject to necessary modifications, apply; and the provisions of this Act applicable to an order made under section 14 shall apply also to any such order as varied under this section.
