Contract – Enforceability. The claimants contended that agreement was reached to renew the licence the first claimant had entered into with the defendant to publish the Middle East edition of Hello! magazine in English in specified countries, and sought specific performance of that renewed contract and cancellation of the licence granted by the defendant to a rival publisher. They further contended that the defendant was estopped by the law of proprietary estoppel from denying the existence of a renewed licence. The Chancery Division, in dismissing the claim, rejected the claimants' case based on both contract and proprietary estoppel.
