 The standard applied in respect of exclusionary clauses is no different from that applicable to other contractual terms that are invalid as a result of considerations of public policy.The question is whether upholding the relevant clause or other term would conflict with the interests of the public as a result of extreme unfairness or other policy issues; in other words, whether a contractual provision, in view of its extreme unfairness or other policy considerations, conflicts with the interests of society.This has very rarely been shown to the courts’ satisfaction.
