The Trade Union Act 1913 was an act of the Parliament of the United Kingdom passed by the Liberal British Government under Prime Minister H. H. Asquith to remedy the situation caused by the 1909 Osborne Judgment, and gave unions the right to divide their subscriptions into a political and a social fund. If union members objected to these political contributions they could contract out of the payment.
The whole act was repealed by the section 300(1) of, and schedule 1 to, the Trade Union and Labour Relations (Consolidation) Act 1992, which came into force on 16 October 1992.
