Banks are preparing to write to customers who have requested the return of overdraft fees in the wake of this week's Supreme Court judgement.
Around a million customers have had their claims on hold. But the victory of the banks over the Office Of Fair Trading means almost all of them will fail - as they stand.
But campaigners tell Money Box they think there is still hope.
At stake in the case is an estimated £2.6bn of annual income for the banks. Campaigners say they're disappointed with the decision. Paul Lewis was at the Supreme Court for the judgement to gauge reaction.
The programme heard from Tony Boorman, Principal Ombudsman, Mike Dailly, principal solicitor at Govan Law Centre, and Angela Knight, chief executive of the British Bankers' Association.
