More than a million claims for a total of around £2 billion have been frozen since July 2007 but the Financial Services Authority said they could now proceed again. It is thought that almost all of them will be thrown out by their banks in the light of today's decision.
It is estimated that a ruling in favour of customers could have triggered as many as 12 million claims worth up to £20 billion.
"This is not only very good news for the banks but for the millions of people who never incur charges", says Jean Price of City law firm CMS Cameron McKenna. "Customers opening a bank account should realise that charges are part of the package."
I had to pay £30 for being £10 overdrawn'
Dancer Billy Burke, from Surbiton, was charged £3,500 in penalty fees by Lloyds TSB between 2004 and last year for going overdrawn on his current account.
He said: "I was always on a tight budget and sometimes went slightly in to the red by accident, rarely more than £10, but they'd penalise me £30 and that would send me further into the red, which would mean more charges. Most of the time I was charged was because I was overdrawn because of their charges."
Mr Burke still owes the bank £300. He said: "I hurt my leg so I can't dance, but the bank are still demanding I pay back £10 a month."
