The following provisions apply in relation to the service of notice of a direction under section 77 and of a summons under section 78, referred to in those provisions as a “ relevant document ”.

Where it is impracticable to serve a relevant document on a person named in it, the document shall be treated as duly served on him if a copy of it is fixed in a prominent place to the vehicle concerned; and where a relevant document is directed to the unnamed occupants of vehicles, it shall be treated as duly served on those occupants if a copy of it is fixed in a prominent place to every vehicle on the land in question at the time when service is thus effected.

A local authority shall take such steps as may be reasonably practicable to secure that a copy of any relevant document is displayed on the land in question (otherwise than by being fixed to a vehicle) in a manner designed to ensure that it is likely to be seen by any person camping on the land.

Notice of any relevant document shall be given by the local authority to the owner of the land in question and to any occupier of that land unless, after reasonable inquiries, the authority is unable to ascertain the name and address of the owner or occupier; and the owner of any such land and any occupier of such land shall be entitled to appear and to be heard in the proceedings.

Section 77(6) applies also for the interpretation of this section.
