The 137th session of the Governing Body of the International Labor Organization (ILO) was held in Geneva from October 29 to November 1, 1957, under the chairmanship of E. Calderon Puig. The Governing Body devoted three sittings to the consideration of matters concerning freedom of association, in connection with which it received from the Director-General a report on the establishment of machinery to determine the facts relating to freedom of association in ILO member states. The report contained proposals to strengthen ILO methods of promoting respect for freedom of association under regular constitutional machinery through factual inquiries and the establishment of independent machinery for the adjustment of disputes. Several members of the Governing Body felt that prior to forming the proposed body the definition of freedom of association would require clarification, while others felt that the tripartite principle should be introduced into the suggested independent commission or that a body representing the Governing Body should be installed between the commission and the Governing Body.
