"A person shall hand over his ticket for inspection and verification of validity when asked to do so by an authorised person."
"A. Can a person be guilty of an offence under Byelaw 18 (2) and 24 of the Railway Byelaws if they did not hand over their ticket for inspection and verification of validity and were not asked to do so by an authorised person but where the ticket was found to be invalid because it was an Oyster card with insufficient funds on it? B. Were the magistrates wrong in law or did they act in excess of their jurisdiction in convicting the appellant of an offence under Bylaws 18(2) and 24 of the Railway Byelaws when they found, (a) that the appellant had not failed to hand over his ticket for information and verification of validity, (b) that the appellant had not been asked to hand over his ticket by an authorised person, and (c) that the appellant had insufficient funds on his Oyster card ticket and it was therefore an invalid ticket?"
