Where plans of a building or of an extension of a building are, in accordance with building byelaws, deposited with a local authority, and it is proposed to erect the building or extension, as the case may be, over any sewer or drain which is shown on the map of sewers required by this Part of this Act to be kept deposited at the offices of the authority, the authority shall reject the plans, unless they are satisfied that in the circumstances of the particular case they may properly consent to the erection of the proposed building or extension, either unconditionally or subject to compliance with any requirements specified in their consent.
Any question arising under the preceding subsection between a local authority and the person by whom or on whose behalf plans are deposited as to whether the site on which it is proposed to erect a building or an extension of a building is over any such sewer or drain as aforesaid, or whether, and if so upon what conditions, a consent ought to be given by the local authority, may on the application of that person be determined by a court of summary jurisdiction.
