None. The re-sale of football tickets is a criminal offence unless done with the authority of the club. Doesn't matter that it's at face value or even less than face value if the season ticket is sold pro-rata and the match-day price is higher. Doesn't even matter if you give it away for nothing. It's illegal and no matter how much Daz Clarke may believe he's doing a service to City fans, even though he's not profiting from it his Facebook page is essentially a criminal enterprise.
Section 166 of the Criminal Justice and Public Order Act 1994 makes it an offence to tout tickets for football matches by creating the following offence for an unauthorised person to:
- Sell a ticket for a designated football match or
- Otherwise to dispose of such a ticket to another person
Now I'm not saying that's a good thing but it is the law.
