The Constitution Alteration (Railways Disputes) Bill 1912 [1] was an unsuccessful referendum held in 1913 that sought to alter the Australian Constitution to give the Commonwealth legislative power over industrial relations in the state railway services.

The Parliament shall, subject to this Constitution, have Legislative power to make laws for the peace, order, and good government of the Commonwealth with respect to: The referendum was not approved by a majority of voters, and a majority of the voters was achieved in only three states.

[3][4] The 1911 referendum asked a single question that dealt with trade and commerce, corporations and industrial matters.

This was an additional resolution that went beyond the previous proposal to directly address industrial disputes in the state railways.

On each of the many occasions a similar question was asked at a referendum the public decided not to vest power in the Commonwealth over these matters.
