Director General of Fair Trading v First National Bank plc [2001] UKHL 52 is the leading case on the Unfair Terms in Consumer Contracts Regulations 1999. It was an action to test the fairness of clauses in loan agreements which secured a bank's commercial interest rates after a debtor that had defaulted and they had been to court to determine their repayment scheme. The House of Lords held that the clause did not fall within the ambit of reg 6(2) and that it was valid in accordance with the fairness test (reg 5(1)). The case was brought by the Director General of Fair Trading (now the Competition and Markets Authority) on behalf of consumers.
