The Permanent International Court of Justice was established in the Covenant, but not by it. The Council and the Assembly have established their Constitutions. Its judges were elected by the Council and the Assembly, and its budget was made available by the latter. The Court should rule on all international disputes submitted to it by interested parties. It may also give an opinion on any disputes or questions submitted to it by the Council or by the Assembly. The Tribunal has been opened to all nations of the world under certain broad conditions.  The last meeting of the League of Nations was held on April 18, 1946 in Geneva.  Delegates from 34 nations attended the General Assembly.  This meeting focused on the liquidation of the League: in 1946, it transferred to the UN about $22,000,000 in assets (United States) (including the Palais des Nations and League archives), returned reserve funds to the nations that had delivered it, and offset the League`s debt.  In his speech at the closing session, Robert Cecil said that within a few months there was a call for an international conference on women in The Hague. The congress coordinated by Mia Boissevain, Aletta Jacobs and Rosa Manus, inaugurated on April 28, 1915, was visited by 1,136 participants from neutral and non-bellicose nations and led to the creation of an organization to become the Women`s International League for Peace and Freedom (WILPF).  Following the conference, two delegations of women were sent to meet with European heads of state in the coming months. They secured the agreement of reluctant foreign ministers, who generally felt that such a body would be ineffective, but agreed to participate in the creation of a neutral mediation body or not to hinder it if other nations agreed and President Woodrow Wilson created a body.
In the midst of the war, Wilson refused.   In the early twentieth century, there were several border conflicts between Colombia and Peru, and in 1922, their governments signed the Treaty of Salomón-Lozano to resolve it.  As part of this contract, the border town of Leticia and its surroundings was ceded by Peru to Colombia, giving Colombia access to the Amazon.  On September 1, 1932, business leaders in the Peruvian rubber and sugar industry, who had lost land, organized an armed acquisition of Leticia.  Initially, the Peruvian government did not recognize the military takeover, but Peruvian President Luis Sánchez Cerro decided to oppose a Colombian renewal. The Peruvian army occupied Leticia, provoking an armed conflict between the two nations.  After months of diplomatic negotiations, governments agreed to League of Nations mediation and their representatives submitted their affairs to the Council. A provisional peace agreement signed by both sides in May 1933 provided for the League to take control of the disputed area, while bilateral negotiations continued.  A final peace agreement was signed in May 1934, leading to Leticia`s return to Colombia, a formal apology from Peru for the 1932 invasion, the demilitarization of the Leticia region, free navigation in the Amazon and putumayo rivers, and a promise of non-aggression.  When the war stopped, Woodrow Wilson presented his plan for a “just peace.” Wilson believed that fundamental shortcomings in international relations created an unhealthy climate that led inexorably to world war.
