If it shall be represented to the Commissioners that it is not expedient or necessary that any works for the cost of which there shall be a subsisting charge, or any part of such works, should be upheld or maintained, the Commissioners may, on having deposited with them a sum, to be fixed by them, to cover all expenses, cause the said works to be inspected by an assistant commissioner, engineer, or surveyor.
If after such inspection and notice to the parties who were served with notice of the application to charge the land or their representatives, and such other persons, if any, as the Commissioners may direct, the Commissioners shall find and certify that is not expedient or necessary that the works or any of them should be upheld or maintained, thereupon the person for the time being bound to make the said periodical payment shall be relieved from all liability in respect of the maintenance of the works referred to in the Commissioners certificate.
