Marinakis v General Motors Holden

The case of *Marinakis v General Motors Holden* concerned a dispute between Mr Marinakis and General Motors Holden (GMH). Mr Marinakis alleged that GMH had engaged in misleading and deceptive conduct in contravention of section 52 of the *Trade Practices Act 1974* (Cth) (now section 18 of the *Australian Consumer Law*). The matter was heard by Gummow and Kirby JJ of the High Court of Australia.

The central legal issue before the High Court was whether GMH had engaged in misleading or deceptive conduct by representing that a particular model of Holden vehicle was "the best car in the world". Mr Marinakis contended that this statement was false and misleading, as the vehicle in question had a history of mechanical defects. The court was required to determine the objective meaning and effect of the advertising statement in the context of consumer protection law.

Gummow and Kirby JJ considered the established principles for assessing misleading or deceptive conduct under the *Trade Practices Act*. Their Honours emphasised that the test is objective, focusing on whether the conduct, viewed as a whole, was capable of misleading or deceiving a significant number of consumers. The court noted that a statement of opinion or a puff, if clearly identifiable as such, might not necessarily be misleading. However, where a statement of opinion is presented as fact, or where it is demonstrably false and likely to influence consumer purchasing decisions, it can constitute misleading conduct. The court analysed the specific advertising material and the nature of the representations made by GMH in light of these principles.

The High Court ultimately found that the statement "the best car in the world" was a form of advertising puffery and not a statement of fact that could be objectively proven or disproven. Therefore, it was not misleading or deceptive conduct in contravention of the *Trade Practices Act*. The appeal was dismissed.
