14. (1) Whenever an order shall have been passed in cases falling under clause (6) of section 7 directing that any road owned by a local authority, which interferes with the drainage of any tract of land, be altered, or that any water-course be constructed under or through such road, the Engineer may require such authority to make such alteration or construct such water course, and in the events of its failing to comply with such requisition in such manner and within such time as the Engineer may prescribe, the Engineer may cause the road to be altered or the water course to be constructed by the officers of the Government or the Authority. (2) The expenses of such alteration or construction shall be borne by the local authority concerned so far as the same shall have been incurred on account of insufficient provisions having been made at the time of the construction of the said road for the natural drainage then existing, and the remainder of the expense, if any, shall be charged upon, and recovered from the owners of the lands benefited, in accordance with the provisions of this Act. If any dispute arises as to the apportionment of expenses under this clause between such authority and the owners of the lands benefited, the dispute shall be decided by the Government or the Authority, whose decision shall be final.
