Pioneer Concrete (Qld) and Ors v Trade Practices Com

Pioneer Concrete (Qld) Pty Ltd and others (the applicants) sought judicial review of a decision by the Trade Practices Commission (the respondent) to refuse to grant authorisations for certain conduct. The applicants, who were involved in the supply of concrete, sought to engage in price fixing and market sharing arrangements. The Commission had refused to grant authorisations for these arrangements on the grounds that they were likely to substantially lessen competition in contravention of the *Trade Practices Act 1974* (Cth).

The central legal issue before the Full Federal Court was whether the Commission had erred in law in its assessment of the likely effect of the proposed arrangements on competition. Specifically, the Court was required to consider whether the Commission had correctly applied the principles of economic analysis in determining whether competition would be substantially lessened, and whether it had given adequate reasons for its decision. The applicants also contended that the Commission had failed to consider certain evidence and had applied an incorrect legal test.

The Court found that the Commission had not erred in law. It held that the Commission was entitled to consider the potential for the proposed arrangements to lead to higher prices and reduced output, and that its assessment of the likely impact on competition was reasonable. The Court affirmed that the Commission's task was to assess the likely future state of competition, and that this involved a degree of forecasting and judgment. The Court also found that the Commission had provided adequate reasons for its decision, and that it had properly considered the relevant evidence.

Consequently, the applications for judicial review were dismissed.
