Dunlop Pneumatic Tyre Co. Ltd. v. New Garage and Motor Co. Ltd. [1915] UKHL 1
The case of Dunlop Pneumatic Tyre Co. v.
Is a contractual provision specifying a fixed sum for breach enforceable under the principles of liquidated damages, or is it an unenforceable penalty?
A clause will be considered a valid liquidated damages clause if it establishes an amount as a genuine pre-estimate of loss that would result from a breach. If it is intended as a deterrent or punishment, it will be classified as a penalty and therefore be unenforceable.
The House of Lords held that the clause specifying £5 per tire was a genuine pre-estimate of damages and therefore enforceable as a liquidated damages clause, not a penalty.
The ruling in Dunlop Pneumatic Tyre Co. clarified the line between permissible liquidated damages and penalties, directly influencing contract drafting and judicial interpretations. It offers crucial guidelines for contract law practitioners by setting out tests to determine enforceability. As such, it remains a pivot in contractual disputes concerning damages clauses, guiding how penalties are perceived relative to damages in jurisdictions worldwide.
