R v Metal Trades Employers' Association; Ex parte Amalgamated Engineering Union, Australian Section

The High Court of Australia considered an application for a writ of prohibition concerning orders made by the Commonwealth Court of Conciliation and Arbitration. The prosecutor, the Amalgamated Engineering Union, Australian Section, sought to prohibit proceedings on an award and subsequent orders made against it by the Arbitration Court. The dispute arose from logs of demand concerning standard hours of work and other industrial matters, leading to an award that included provisions regarding overtime.

The legal issues before the High Court included whether a specific provision of the award, prohibiting an organisation from being a party to or concerned in any ban on overtime, was within the ambit of the industrial dispute. Further, the court had to determine if an order made under section 29(b) of the Commonwealth Conciliation and Arbitration Act 1904-1949, requiring the union to cause its members to work overtime without a ban, exceeded the court's power to order compliance. The court also considered whether an injunction granted under section 29(c) of the Act, enjoining the union from contravening the Act by being concerned in overtime bans, was valid, and whether the Arbitration Court possessed the power to punish disobedience of its orders as contempt of court.

The High Court, by majority, held that the overtime ban prohibition in the award was within the ambit of the dispute. However, a majority of the court found that the order made under section 29(b) exceeded the Arbitration Court's power, as the award did not bind the organisation to procure its members to work overtime. Furthermore, a majority determined that the order under section 29(c) was invalid because the power conferred by that section was limited to contraventions of the Act itself, not contraventions of awards or orders. The court also held that the Arbitration Court did not have an inherent power to punish disobedience as contempt, as the Act provided specific mechanisms for dealing with such matters.

Consequently, the High Court ordered that a writ of prohibition should issue to prevent further proceedings on the orders made under sections 29(b) and 29(c) of the Act, as well as on the order purporting to impose a fine for contempt of court.
