Coyne v Citizen Finance Ltd

Coyne, the applicant, sought to recover money paid under a loan agreement with Citizen Finance Ltd, the respondent. The applicant alleged that the loan agreement was void for illegality, as it contravened s 50 of the *Trade Practices Act 1974* (Cth) (now s 51AC of the *Competition and Consumer Act 2010* (Cth)). The High Court of Australia considered the appeal from the Supreme Court of New South Wales.

The central legal issue before the High Court was whether the loan agreement was void for illegality by reason of contravening s 50 of the *Trade Practices Act 1974* (Cth). This required the Court to determine the scope and application of s 50, particularly in relation to loan agreements and the concept of "anti-competitive conduct." The Court also had to consider the consequences of such a contravention, specifically whether it rendered the agreement void *ab initio*.

The High Court held that s 50 of the *Trade Practices Act 1974* (Cth) was concerned with conduct that substantially lessened competition in a market. It was not intended to apply to individual loan agreements that did not have such an effect. The Court reasoned that the applicant had failed to establish that the loan agreement itself constituted conduct that contravened s 50. Therefore, the agreement was not void for illegality on this ground. The Court affirmed the principles that illegality must be established by reference to the specific conduct and its impact on competition, and that a contract is not automatically void for illegality merely because it is entered into by a party who may have engaged in other conduct that contravened the Act.

The High Court dismissed the appeal.
