If a local authority, when required by the Minister to make building byelaws in relation to any of the matters with respect to which they are by this Part of this Act empowered to make such byelaws, do not within three months after such requisition make in relation to that matter byelaws satisfactory to him, the Minister may himself make byelaws in relation thereto.
If the Minister is satisfied that the erection of any buildings is, or is likely to be, unreasonably impeded in consequence of any building byelaws, he may for the purpose of removing the impediment require the local authority to revoke those byelaws and to make such new byelaws as he may consider necessary, and, if the authority do not within three months after such requisition comply therewith, the Minister may himself for that purpose revoke the byelaws, and make such new byelaws as he may consider necessary.
Any byelaws made by the Minister under this section shall have effect as if they had been made by the local authority and confirmed by the Minister.
