Background

  • The Commonwealth Court of Conciliation and Arbitration was created under the Conciliation and Arbitration Act 1904 (Cth).

  • It exercised both:

    • Arbitral (non-judicial) powers — making industrial awards; and

    • Judicial powers — enforcing awards and punishing for contempt.

  • The Boilermakers’ Society was fined for contempt and challenged the Court’s constitutional power to do so.

⚖️ Issue

Whether a single body can validly exercise both judicial and non-judicial powers under the Australian Constitution.

⚖️ Decision

  • High Court (majority: Dixon CJ, McTiernan, Fullagar & Kitto JJ):

    • The judicial power of the Commonwealth is vested exclusively in courts created under Ch III of the Constitution.

    • Such courts cannot be vested with non-judicial powers (except those strictly incidental to judicial power).

    • A body combining non-judicial and judicial powers is constitutionally invalid to exercise judicial power.

  • Privy Council (Viscount Simonds, Lord Morton, Lord Cohen, Lord Tucker, Lord Somervell) affirmed the High Court’s reasoning and orders.

Principle

  • Judicial power of the Commonwealth can only be exercised by Chapter III courts.

  • Non-judicial bodies cannot be given judicial power, and Chapter III courts cannot be given non-judicial powers.

  • This strict separation:

    • Protects due process by ensuring coercive powers are exercised only by independent judges with constitutional guarantees;

    • Shields property and legal rights from administrative or executive encroachment;

    • Guarantees access to judicial review and impartial adjudication of rights.
