(3) In any proceedings under the provisions of subsection (2), the court may inquire whether any requirement contained in any notice served, or any work done, by the Authority under the provisions of this section was reasonable and whether the expenses incurred by the Authority in doing that work, or any part thereof, ought to be borne wholly or in part by the person upon whom the notice was served, and may make such order concerning those expenses or their apportionment as appears to it to be just having regard to all the circumstances.

Provided that, in carrying out any operation in pursuance of the provisions of this subsection, the Authority shall not make any structural alteration to such premises or vessel or such part of any premises or vessel, nor move any fixture or any fittings, furniture or equipment of a substantial nature, or otherwise cause any unreasonable inconvenience to the occupants of such premises or vessel or such part of any premises or vessel.
(5) Where, in pursuance of the provisions of subsection (4), the Authority has placed in any premises or vessel any trap or bait container or any bait or other substance, any person who, without lawful authority or excuse, knowingly removes or destroys such trap, bait container, bait or substance or otherwise interferes therewith, or knowingly causes, suffers or permits any other person or any domestic animal or bird to remove, destroy or interfere with such trap, bait container, bait or substance, shall be guilty of an offence.
