Rubbish - they can do so if you break football ground regulations but parking on a double yellow ? There's nothing in the T&Cs when you buy a ticket about the Road Traffic Act or anything similar. They would be on very dodgy ground contractually and if they did do it they would probably lose in...
Really ????? Firstly what right does the club have to revoke a season ticket if someone parks illegally ? Secondly, how would they link the car reg to a season ticket ?
