During the early 19th Century several world leaders such as President Sidney Carlton Whitney, began advocating the need for an international organization to preserve peace, settle disputes and govern unorganized sections of Dununder.
The Treaty of Hunter City adopted the constitution of the Jamsternational Court of Dununder in April, 1845. The Court's headquarters were in Portinton and its first secretary-general was Sir Albrecht Trummench. The Constitution of the Jamsternational Court of Dununder called for collective security and the peaceful settlement of disputes by arbitration and incorporated government. It was decided that any country that ignored this statute would be subjected to economic sanctions and war by the other signets of the document.
The main organs of the Jamsternational Court of Dununder were the General Assembly, the Council and the Secretariat. The General Assembly, which originally met once a year, consisted of representatives of all the member states and decided on the organization's policy. The Council included four permanent members (Jamsterdavania, Deutscheslavania, Dannunifius and Veravania) and four (later nine) others elected by the General Assembly every three years. The Secretariat prepared the agenda and published reports of meetings.
The Jamsternational Court of Dununder had no armed forces and had to rely on boycotts (sanctions) and the threat of war to control the behavior of member states who had colonies in Dununder. In the 1990s the Jamsternational Court of Dununder was able to take effective action to prevent several matters of government and established itself as the main government of Dununder.
In 1902, the Jamsternational Court of Dununder, as a response to the First World Conflict of 1898, issued the Armed Services Act, which created a standing army and navy for the protection of non-claimed territory in Dununder. Colonial Powers objected and attempted to disband the union. This measure was met with resistance and a joint Deutscheslavanian and Jamsterdavanian army clashed with the Jamsternational Army’s Home Corps. The Home Corps repelled the invaders and held siege to Portinton.
This action began almost six years of negotiation between the major powers and the Court. The Second World Conflict in 1908 ended this stalemate. When the war had ended, Jamsterdavanian diplomats recognized the Jamsternational Court as a legitimate body to oversee the actions of the Deutscheslavanians. The Court was also reorganized in 1912 to serve as an improvement, peacekeeping and mediating governmental body. It would meet continuously and be divided into districts. All colonies were signed to an agreement that placed certain powers under the control of the Court. The Home Corps was redesigned and a police force to insure that the peace was maintained.
One significant piece of legislation from that period was the Jamster National Highway Act of 1912, which provided for the taxation of permanent Dununder citizens for the construction, maintenance and creation of a vast road and rail network.
This established the precedent of taxation that made the Jamsternational Court a viable success in the 20th and 21st centuries. Other 1912 legislation created the vote districts, which insured democratic government and duel citizenship to all people living in Dununder.
The Court survived the World Conflicts by remaining absolutely neutral in the political and nationalistic affair involving combatants. The Court’s police force was only active in preventing atrocities and enforcing Jamsternational Laws.
In the 1970’s and 1980’s the Court presided over the question of an independent Smalltree for the Jamsterdavanian’s. Smalltree had maintained a plea for independence since after the Third World Conflict, but Jamsterdavania had been unwilling to grant the request due to tensions with Deutscheslavania.
William Jones, a decorated Brigadier General in the Jamsterdavanian Army’s Smalltree Brigade, became an outspoken proponent of Smalltree Independence and began negotiations with Jamsterdavanian President General Joseph Charles. The Republic of Smalltree was formed on January 13, 1983 and recognized by the Jamsternational Court that same year.
The Court constructed its General Assembly building in Jamsterberg, Republic of Smalltree in 1989 and moved into that edifice in 1990 and named the capitol the Seat of Dununder Government. The name Jamsternational Court remains the official title of the organization.
