Exemption clauses (also called exclusion or limitation clauses) cap or exclude a party’s liability. Once viewed as a “social nuisance”, they are now recognised as having a legitimate role in regulating commercial risk. To be effective, a clause must be validly incorporated, must cover the loss as a matter of construction, and must survive statutory scrutiny under the Unfair Contract Terms Act (UCTA) 1977.

Valid Incorporation

  • Timing of notice: notice must be given before or at the time of contracting. In Thornton v Shoe Lane Parking, terms on a ticket issued by a machine after the contract formed were “too late”.
  • The “red hand” rule: a particularly onerous or unusual clause needs extra steps to bring it to notice — Lord Denning’s clause printed in “red ink with a red hand pointing to it”.
  • Reasonable sufficiency: the test is whether the party did what was “reasonably sufficient” to give notice of the condition.

Interpretation and Construction

  • The “clear words” rule: parties are not taken to give up valuable rights without express, clear language; the more valuable the right, the clearer the words required.
  • Negligence: it is safest to use the word “negligence” expressly; under the traditional Canada Steamship test, general words cover negligence only if wide enough and there is no other head of damage they might address.
  • Exclusion vs. limitation: limitation clauses (capping liability) are construed less strictly than total exclusions.
  • Fundamental breach: no rule of law automatically invalidates a clause for a fundamental breach; it is a matter of construction — the more serious the breach, the clearer the words must be.

Statutory Control (UCTA 1977)

  • Negligence (s 2): liability for death or personal injury from negligence can never be excluded; other loss only if reasonable.
  • Contractual breach (s 3): on written standard terms, a party cannot exclude liability for its own breach unless the term is reasonable.
  • The reasonableness test (s 11): assessed at the time of contracting, weighing relative bargaining power, any inducement to agree, and the availability of insurance.
  • Onus of proof: on the party relying on the clause to prove it reasonable.

The Definitional Debate

A central tension is whether an exclusion clause is a defence to a breach, or whether it defines the primary obligation (selling a horse “warranted sound except for hunting”). English courts generally view such clauses in defensive terms, allowing UCTA to “bite” on them as attempts to restrict liability.
