It was reported in the Daily Telegraph a few days ago, I don't recall any specific details other than it was the outcome of a claim made by a customer about a bad overseas hotel booking experience, resulting in them having to re-book elsewhere.
They tried to claim their out of pocket costs against the UK card company and the booking site under Section 75 of the Consumer Credit Act. I think they took the matter to Court, but failed: the ruling was that their contract with the booking site was simply to arrange a booking, which they correctly did, so there was no possibility of liability under Section 75.
They were referred by the booking site and card company to the hotel, who were not in any way interested.
