A handful of decisions define the modern law.
Parker v South Eastern Railway (1877) established that a clause on a ticket or in a document may be incorporated if reasonable notice is given before or at the time of contract. The claimant deposited a bag at the defendant's cloakroom and received a ticket stating 'see back' with conditions limiting liability to £10. The ticket was lost. The Court of Appeal held that the question was whether the railway company did what was reasonably sufficient to give notice of the condition; if so, the customer was bound whether or not he actually read it. The case remains the foundation of the reasonable-notice doctrine and is applied weekly in county courts and the Commercial Court alike.
Olley v Marlborough Court Ltd (1949) clarified timing. A couple booked into a hotel; a notice in the bedroom purported to exclude liability for lost property. Property was stolen owing to the hotel's negligence. The Court of Appeal held that the contract was made at reception; the notice came too late to be incorporated. The principle—that notice must be given before or at the moment of contracting—is now elementary but was still being litigated in Thornton v Shoe Lane Parking Ltd [1971] 2 QB 163, where the Court of Appeal held that an automatic ticket machine could not incorporate unusual terms unless adequate notice was given at the point of offer and acceptance, not merely on the ticket itself.
Photo Production Ltd v Securicor Transport Ltd (1980) laid to rest the doctrine of fundamental breach as a rule of law. Securicor contracted to provide security patrols of Photo Production's factory. An employee deliberately started a fire, destroying the factory. The contract contained a widely drafted exclusion clause. The House of Lords held that the question was one of construction: did the clause, on its true interpretation, cover the breach? It did. There was no rule of law that a fundamental breach or a 'deliberate' breach automatically defeated an exclusion clause. Lord Wilberforce emphasised that in commercial contracts between parties of equal bargaining power, the court should respect the parties' allocation of risk. The case marked a decisive shift from judicial paternalism to a modern, commercial approach. It should be read alongside the statutory developments: UCTA had just come into force, and the House of Lords was content to leave legislative control to Parliament while restoring freedom of contract at common law.
George Mitchell (Chesterhall) Ltd v Finney Lock Seeds Ltd (1983) was the first House of Lords decision to apply UCTA's reasonableness test (then in the Supply of Goods (Implied Terms) Act 1973). The defendants supplied cabbage seed which proved to be defective, causing heavy loss. The contract limited liability to replacement of the seed or refund of the price (£192). The loss exceeded £60,000. The House of Lords held that the limitation clause was unreasonable. Lord Bridge identified several factors: the defendants could have insured; they could not justify the term on negotiation or bargaining strength; they had on previous occasions paid compensation beyond the limit; and the breach arose from their negligence. The decision established that the burden of proving reasonableness lies on the proferens and that judges should not too readily interfere with the trial judge's evaluation (it is not an appeal on the legal test but on the evaluative judgment).
Smith v Eric S Bush (1990) extended UCTA to negligent misstatement and professional services. A surveyor negligently valued a house for a building society. The claimant house-buyer relied on the valuation. A disclaimer purported to exclude liability for negligence. The House of Lords held that UCTA s 2(2) applied and the disclaimer was unreasonable. It was neither fair nor reasonable for a surveyor to impose on a purchaser of modest means the risk of negligence. The decision is notable for its integration of common law (duty of care in Hedley Byrne) and statute (UCTA), and for its willingness to strike down professional disclaimers where there is inequality of bargaining power or information asymmetry.
Interfoto Picture Library Ltd v Stiletto Visual Programmes Ltd (1989) revitalised the doctrine of onerous or unusual terms. The defendants ordered photographic transparencies from the claimants. A delivery note contained 47 transparencies and conditions including a 'holding fee' of £5 per transparency per day after 14 days. The defendants returned them late; the claimants invoiced over £3,700. The Court of Appeal held that the clause was not incorporated. Where a term is particularly onerous or unusual, the party seeking to rely on it must take reasonable steps to draw it to the other's attention. Mere reference to conditions on the back is insufficient. The principle operates at the incorporation stage, not construction, and has been applied in contexts ranging from online terms and conditions to commercial contracts, though the threshold for 'unusual' is higher in commercial settings.
These cases, taken together, illustrate the enduring influence of the common law even in a statutory era. Incorporation and construction remain threshold questions, and courts continue to police exclusion clauses through interpretative rigour where statutory control does not apply.
