On the application of any local authority directly concerned, the Secretary of State may, subject to the provisions of this section, by order repeal or amend any provision in any local Act passed before this Act, or in any Act passed before this Act and confirming a provisional order, where it appears to him that the provision is inconsistent with, or has become unnecessary in consequence of, any provision of this Act.

Before making an order under this section the Secretary of State shall consult with any local authority appearing to him to be concerned, not being a local authority by whom an application for the making of the order was made.
