If the business is closed but the public still have access then it still falls
Under the rta. Ie your tesco car park at night when store is closed.
Agree.
If it was a private carpark and it was closed to the public at night and gates were closed so there was no public access, then I think you would be ok (as long as you had permission to be there). I cant see the police climbing over a closed gate to give you a ticket either.
Cheers
