Antico v Heath Fielding Aus Pty Ltd

The High Court of Australia considered a dispute between Antico and Heath Fielding Aus Pty Ltd concerning the enforceability of a restraint of trade clause. Mr Antico had been employed by Heath Fielding, a firm of insurance brokers, and upon termination of his employment, sought to engage in business activities that Heath Fielding alleged were in breach of a restrictive covenant contained within his employment agreement.

The central legal issue before the High Court was whether the restraint of trade clause in Mr Antico's employment contract was void as being contrary to public policy, and therefore unenforceable. This required the Court to assess the reasonableness of the restraint in terms of its duration, geographical scope, and the nature of the activities it sought to prohibit, in order to determine if it went beyond what was necessary to protect the legitimate business interests of Heath Fielding.

The High Court ultimately found that the restraint of trade clause was unreasonable and therefore void. The Court reasoned that the scope of the restriction, particularly its duration and geographical reach, was wider than necessary to protect Heath Fielding's proprietary interests, such as its confidential information and customer connections. The principles applied by the Court centred on the established common law doctrine that restraints of trade are prima facie void unless they can be shown to be reasonable, both in the interests of the parties and the public. The Court determined that Heath Fielding had failed to demonstrate the reasonableness of the restraint in this instance.
