International Air Transport Association v Ansett Australia Holdings Limited

The High Court of Australia considered a dispute between the International Air Transport Association (IATA) and Ansett Australia Holdings Limited (in liquidation) concerning the interpretation and application of the *Trade Practices Act 1974* (Cth) (now the *Competition and Consumer Act 2010* (Cth)). The core of the dispute involved whether IATA's conduct in relation to the sale of air travel by Ansett constituted a contravention of the Act, specifically concerning alleged anti-competitive practices.

The central legal issues before the High Court were whether IATA, through its agency agreements and the rules governing the sale of air travel, had engaged in conduct that had the purpose or effect of substantially lessening competition in a market, contrary to section 45 of the *Trade Practices Act 1974*. Further, the Court had to determine whether IATA's conduct amounted to a misuse of market power, contrary to section 46 of the Act, and whether certain provisions of the IATA agency resolutions were void as being contrary to public policy.

The High Court's reasoning focused on the nature of the market for the sale of air travel and IATA's role within it. The Court analysed whether the IATA agency resolutions, which regulated the terms on which travel agents could sell air tickets, had the purpose or effect of substantially lessening competition. It considered the economic realities of the air travel market and the extent to which IATA's rules restricted competition among travel agents and airlines. The Court also examined whether IATA possessed substantial market power and, if so, whether it had misused that power in a way that contravened section 46. The principles applied involved a detailed examination of the statutory provisions and their application to the specific conduct of IATA and its members in the context of the global air travel industry.

The High Court ultimately found that IATA's conduct did not contravene section 45 of the *Trade Practices Act 1974* as alleged, nor did it amount to a misuse of market power under section 46. The Court also held that the relevant IATA resolutions were not void as being contrary to public policy. Consequently, the appeal by Ansett was dismissed.
