Did the Supreme Court actually make a hint regarding another solution?
Yes, the Supreme Court did make a hint about an alternative by which the charges can be challenged. Remember, the ruling never said anything about the charges being fair. They only said that the Office of Fair Trade has no right to make a ruling and that the charges are in fact fees for the use of a current account. The law was silent about the excessive amount charge. In fact, the judge even hinted that the ruling made does not disallow the right of people to challenge the charges on the basis of an imbalance as mentioned in clause 5 of the Unfair Terms in Consumer Contracts Regulations.
