Brisbane Shipwrights' Provident Union v Heggie

Brisbane Shipwrights' Provident Union (the Union) brought an action against Heggie, alleging that Heggie had induced an employer to dismiss an employee and to refrain from employing him further. The dispute concerned alleged deliberate interference with the rights of others, actuated by a desire to do harm, and interference with trade, within the context of trade union activities, trade disputes, and trade competition. The matter came before the High Court of Australia on a direct appeal from a judgment founded on the verdict of a jury.

The central legal issues before the High Court were whether the Union's actions constituted an unlawful interference with Heggie's rights, and whether such interference was justifiable in the circumstances, particularly in light of the provisions of the Queensland Criminal Code, sections 534 and 543, which dealt with matters relating to trade and combinations. The Court was required to consider the nature of trade disputes and the extent to which trade unions could lawfully engage in conduct that might impact individual employment.

The Court's reasoning focused on the principles of tortious interference with contractual relations and the broader concept of unlawful conspiracy. It was held that while trade unions have a right to engage in trade disputes and to take action to protect the interests of their members, this right is not absolute. The Court considered whether the Union's conduct was actuated by malice or a desire to cause harm, rather than a legitimate pursuit of trade union objectives. The application of sections 534 and 543 of the Queensland Criminal Code was crucial in determining whether the Union's actions were protected or rendered unlawful by statute. The Court ultimately found that the Union's actions, as established by the jury's verdict, were not justifiable and constituted an unlawful interference with Heggie's rights.
