City Motors (1933) Pty Ltd v Southern Aerial Super Service Pty Ltd

The High Court of Australia considered an appeal concerning a dispute between City Motors (1933) Pty Ltd and Southern Aerial Super Service Pty Ltd. The core of the disagreement revolved around the interpretation and enforceability of a restrictive covenant contained within a deed of lease. City Motors, as the lessor, sought to prevent Southern Aerial Super Service, the lessee, from operating a competing business on adjoining premises.

The central legal issue before the Court was whether the restrictive covenant, which purported to prevent the lessee from carrying on a business of a similar nature to that of the lessor on any other land owned by the lessor, was valid and enforceable. This required the Court to examine the principles of restraint of trade and the extent to which such covenants could lawfully restrict a party's commercial activities.

The Court's reasoning focused on the established legal principles governing restraints of trade, particularly those found in contracts. It was held that for a restraint of trade to be valid, it must be reasonable in the interests of the parties and not contrary to the public interest. The Court analysed the scope and duration of the covenant, considering whether it went beyond what was necessary to protect the legitimate business interests of City Motors. The principles of reasonableness, as applied to covenants in leases and other commercial agreements, were central to the determination.

Ultimately, the High Court found that the restrictive covenant was void as an unreasonable restraint of trade. The appeal was dismissed, and the orders of the lower court were affirmed.
