As did the Court of Appeal Longmore LJ:
I cannot bring myself to hold that it is the duty of a tour operator dealing with rational adults on a winter holiday to repeat simple warnings already given with clarity or to point out obvious dangers of ice on the road and the relative safety of snow at its side. So to hold would only encourage potential claimants to believe that whenever an injury occurs someone must be to blame. That is not what the law of negligence is about.
Common sense prevailed again.
