Really? What forums would this be?
Because the financial ombudsman has acknowledged it means the cases are pretty much dead.

I'd take their view over random websites (especially if it is one of the sites that mistakenly pushed this issue and are now trying to save face...)
Clause 5(1) of the UTCCR states - "A contractual term which has not been individually negotiated shall be regarded as unfair if, contrary to the requirement of good faith, it causes a significant imbalance in the parties’ rights and obligations arising under the contract, to the detriment of the consumer."
This is the angle that they are looking at, as the FOS used a different part of the UTCCR for their court case.
