Airservices Australia v Canadian Airlines

Airservices Australia and Canadian Airlines International Ltd were parties to litigation before the High Court of Australia concerning the interpretation of a contract for air navigation services. The dispute arose from a claim by Airservices Australia for unpaid fees for services provided to Canadian Airlines, which Canadian Airlines disputed on various grounds, including allegations of misleading and deceptive conduct.

The High Court was required to determine, among other things, whether Airservices Australia had engaged in misleading or deceptive conduct in contravention of the *Trade Practices Act 1974* (Cth) (now the *Competition and Consumer Act 2010* (Cth)) in its dealings with Canadian Airlines regarding the provision of air navigation services and the associated charges. A further issue was the proper construction of the contract between the parties and whether Canadian Airlines had validly terminated it.

The Court considered the nature of the representations made by Airservices Australia and whether they were misleading or deceptive in the context of the contractual relationship. It examined the principles of contractual interpretation and the circumstances under which a party may be entitled to terminate a contract. The Court ultimately found that Airservices Australia had not engaged in misleading or deceptive conduct and that Canadian Airlines was liable for the unpaid fees.

The High Court ordered that Canadian Airlines pay the outstanding fees to Airservices Australia, along with interest and costs.
