Bain v Frank G O'Brien Ltd

The High Court of Australia considered an appeal concerning a dispute between Bain and Frank G. O'Brien Ltd. The core of the disagreement involved the interpretation and enforceability of a deed of covenant entered into between the parties.

The central legal issue before the High Court was whether the deed of covenant, which purported to restrict the appellant's ability to carry on a particular business, was void for uncertainty or otherwise unenforceable. The court was required to determine the precise scope of the covenant and whether it imposed an unreasonable restraint of trade.

The High Court, in allowing the appeal, reasoned that the covenant was too wide in its geographical scope and the range of activities it sought to restrain. The judges applied established principles of contract law concerning certainty and the doctrine of restraint of trade, finding that the covenant went beyond what was reasonably necessary to protect the legitimate business interests of the respondent. Consequently, the deed was held to be void and unenforceable.
