Robert Giarrusso and Transport Union Workers of Australia v Ampol Petroleum (Vic) Pty Ltd

In the Federal Court of Australia, the case of Robert Giarrusso and Transport Union Workers of Australia against Ampol Petroleum (Vic) Pty Ltd was heard. The dispute involved allegations of a secondary boycott, specifically a black ban on barge servicing for an off-shore seismic exploration vessel. The court was tasked with determining whether such a ban was indeed imposed by the union and if it amounted to an illegal secondary boycott under the Trade Practices Act. The legal issues centred on the interpretation of the Act, the burden of proof in such cases, and the sufficiency of the evidence presented to establish the alleged actions.

The court carefully examined the evidence presented and concluded that there were significant deficiencies in proving the imposition of a ban. The lack of direct evidence and the reliance on inferences and speculation did not meet the required standard of proof. The court emphasised that to establish a secondary boycott, it must be shown that the union imposed a ban as part of its activities, and this was not satisfactorily demonstrated in this case. The evidence provided was insufficient to meet the burden of proof, and the court found no basis for concluding that a secondary boycott had occurred.

Given the findings, the court determined that the case did not establish the alleged secondary boycott, and the union's actions were not unlawful under the Trade Practices Act. The court ruled that the case was not one of law but rather one of insufficient evidence. Consequently, the decision was made to dismiss the claims made by the plaintiffs. This outcome highlights the importance of clear and direct evidence in trade practices cases, particularly when allegations of significant economic actions by unions are involved.
