What if the landowner decides to let them stay on the land temporarily?
Unless the landowner has already obtained planning permission for a caravan site or is a farmer and the Gypsies/Travellers are helping with fruit picking,etc then the landowner could be in breach of the Planning Acts and the Acts dealing with the licensing of caravan sites. You may wish to seek further advice from the Council’s Gypsy and Traveller Liaison Officer who deals with illegal encampments.
