I’d question the legality of that notice.
Trespass is a civil matter so can it be a criminal offence? My understanding was it had to be upgraded from trespass to criminal damage for it to be a crime.
No, there are certain types of trespass that can be criminal
All tresspass is criminal offence no ?
No, its normally a civil tort
However, in this case there is a specific piece of legislation involved
http://origin-www.legislation.gov.uk/uksi/2005/1918/article/42/made
level three – so max £1000 fine
(3) No person shall be convicted of an offence under this article unless it is shown that a notice warning the public not to trespass upon the authorised busway was clearly exhibited and maintained at the station or other stopping place or level crossing on the authorised busway nearest the place where the offence is alleged to have been committed.
No sign, no offence…
