Richard Pike, a partner at Fieldfisher, told The Telegraph that those who bought tickets could join forces to bring collective action against Ticketmaster.
“They could be for breaches of consumer law, or common law actions, misrepresentation,” he said. “There are all sorts of things they could do there.
“They’d have to bring a High Court claim. The way it works is, like the adverts you see on TV saying, ‘Have you had an accident? Did you buy PPI?’, it would be like, ‘Did you buy an Oasis ticket for quite an expensive price?’
“You could theoretically do that. In terms of the merits of action, I think there are arguments there.
“I don’t know about you but I wasn’t expecting there to be this dynamic pricing.
“It only became apparent after I’d been on the phone for quite some time already.
“You can see psychologically there’s commitment there. When you’ve waited that long already, you’re liable to pay more than you otherwise would. They are taking advantage of you.”
Mr Pike added that viability of the action would depend on the total value of damages, which would only be several hundreds of pounds per person and may not cover the costs of bringing legal action.
By contrast, joint PPI claims can seek damages worth thousands of pounds per person.
Tickets for the Britpop band’s long-awaited reunion tour were only available through Ticketmaster, the online ticket seller, which raised prices because of intense demand.
