If a person on whom a notice has been served under subsection (1) of the last preceding section objects to the requirement of the local authority on any of the following grounds, that is to say that:—
he may, within twenty-eight days after service on him of the notice, appeal to the Minister and, if he so appeals, the authority shall not take any further steps under the notice until they have been authorised so to do by the Minister.
Upon an appeal to him under this section the Minister may either disallow the requirement of the local authority or allow it with or without modifications, and, if he allows it, shall order the authority to proceed with the proposed works, or those works as varied by the order, either forthwith or in the event of the works not being executed by the owner or owners within a time limited by the order.
The Minister may by his order, if he thinks it equitable so to do, apportion the expenses of providing the supply between the owner or owners concerned and the local authority, or may vary any such apportionment which the authority propose to make, so, however, that in no case shall any owner be required to pay more than twenty pounds in respect of any one house.
