Seamen's Union of Australasia v Commonwealth Steamship Owners' Association

The Seamen's Union of Australasia brought proceedings against the Commonwealth Steamship Owners' Association concerning the validity of an industrial award made under the *Transport Workers Act 1928-1929* (Cth). The dispute centred on penal provisions within the award that prohibited actions intended to prevent, delay, or hinder the departure, working, or use of ships.

The High Court of Australia was required to determine whether the penal provisions of the award were validly made under the *Transport Workers Act 1928-1929*. Specifically, the Court had to consider whether the Act conferred the power to include such prohibitions and whether the award, as it stood, exceeded the scope of that legislative authority.

The Court reasoned that the *Transport Workers Act* did not grant the Arbitration Court the power to make awards containing penal provisions of the nature challenged. It held that the Act's purpose was to regulate industrial conditions and disputes, not to create a mechanism for enforcing compliance through penalties for actions that might indirectly affect shipping operations. The Court applied the principle that industrial tribunals must act within the powers conferred by the relevant legislation, and that penal provisions must have a clear statutory basis.

Consequently, the Court found the penal provisions of the award to be invalid.
