(1) Where a relevant work is abandoned or suffered to fall into decay, the Secretary of State may by notice in writing require the Council at their own expense either to repair and restore the work or any part thereof, or to remove the work and restore the site thereof to its former condition, to such an extent and within such limits as the Secretary of State thinks proper. (2) Where a work consisting— (a) partly of a relevant work; and (b) partly of works on or over land which is not on, under or over the waters of the City Docks; is abandoned or suffered to fall into decay and the works mentioned in subparagraph (b) above are in such condition as to interfere or to cause reasonable apprehension that they may interfere with the right of navigation or other public rights, the Secretary of State may include those works, or any portion thereof, in any notice under this article. (3) If, on the expiration of 30 days from the date when a notice under this article is served upon the Council, they have failed to comply with the requirements of the notice, the Secretary of State may execute the works specified in the notice and any expenditure incurred by the Secretary of State in so doing shall be recoverable from the Council.
