The Secretary of State may by order made by statutory instrument subject to annulment in pursuance of a resolution of either House of Parliament repeal or amend, on such date as may be appointed in the order, any local statutory provision in so far as that provision appears to him to be inconsistent with, or to have become unnecessary or to require alteration in consequence of, any provision of this Act.

Different dates may be appointed under subsection (1) above in respect of different local statutory provisions; and any such date may, where the local statutory provision is one to which section 225(6) of the 1973 Act (which prospectively repeals certain such local statutory provisions) applies, be earlier than that on which the local statutory provision would cease, under the said section 225(6), to have effect.
