The Conciliation and Arbitration Act 1904 was an Australian Commonwealth Government Act "relating to Conciliation and Arbitration for the Prevention and Settlement of Industrial (workplace) Disputes extending beyond the Limits of any one State", and was assented to on 15 December 1904, almost four years after federation. Alfred Deakin (Protectionist), Chris Watson (Labor), and George Reid (Free Trade) all served at one point as Prime Minister in 1904 due to disagreements over the specifics of the bill.
The chief objects of this Act were:
This document introduced the rule of law in industrial relations for the whole nation by establishing the Commonwealth Court of Conciliation and Arbitration. The Bill was drafted and introduced by Charles Cameron Kingston, Australia's pioneer of compulsory arbitration, drawing on New Zealand legislation (New Zealand's Industrial Conciliation and Arbitration Act 1894). Kingston resigned when Cabinet refused to allow the Bill to cover seamen on coastal ships. Labor Members succeeded in introducing an amendment to have the Bill cover State government employees, a provision Deakin believed to be unconstitutional.
