s 14 Supplementary orders.
(1) There may be inserted in any scheme a provision empowering any responsible authority, or any local authority or county council concerned who are not a responsible authority, to make orders (in this Act referred to as " supplementary orders " ), or to adopt, with or without modifications, supplementary orders proposed by owners of land, for supplementing the provisions of the scheme, as respects any part of the area to which it applies, by adding to it provisions with respect to any matters for which provision may be made by a scheme and for varying it in so far as may be necessary or expedient. (2) The provisions of this Act with respect to the approval of schemes by the Minister, the laying of schemes before Parliament, and the validity and date of operation of schemes shall apply in relation to a supplementary order, as if it were a scheme. (3) A supplementary order may be revoked or varied by a subsequent supplementary order made by the same authority, but so long, and in so far, as it continues to be operative, shall be deemed to form part of the scheme to which it relates.
