are you sure about that? i talked to a lawyer about this. he may have been wrong, of course. and the law may have changed since. he told me that the planning permission also granted right of way. that is it gives you the right to cross the pavemant and enter the highway. what is illegal is to block this right of way. so if you’re parked on the property and can’t get out the police will come. if you’re not they won’t.
