The Permanent Court of Arbitration, an international arbitration court at The Hague, is created when the Senate of the Netherlands ratifies an 1899 peace conference decree.

The Permanent Court of Arbitration (PCA) is an intergovernmental organization headquartered at the Peace Palace, in The Hague, Netherlands. Unlike a judicial court in the traditional sense, the PCA provides administrative support in international arbitrations involving various combinations of States, State entities, international organizations and private parties. The cases span a range of legal issues involving territorial and maritime boundaries, sovereignty, human rights, international investment, and international and regional trade. The PCA is constituted through two separate multilateral conventions with a combined membership of 125 Contracting Parties. The PCA is not a United Nations agency, but has been a United Nations observer since 1993.

The Hague is the capital city of the South Holland province of the Netherlands. With a population of over half a million, it is the third-largest city in the Netherlands. Situated on the west coast facing the North Sea, The Hague is the country's administrative centre and its seat of government, and has been described as the country's de facto capital since the time of the Dutch Republic, while Amsterdam is the official capital of the Netherlands.

The Senate is the upper house of the States General, the legislature of the Netherlands. Its 75 members are elected on lists by the members of the twelve States-Provincial and four electoral colleges for the Senate every four years, within three months of the provincial elections. All provinces and colleges have different electoral weight depending on their population.

The Hague Conventions of 1899 and 1907 are a series of international treaties and declarations negotiated at two international peace conferences at The Hague in the Netherlands. Along with the Geneva Conventions, the Hague Conventions were among the first formal statements of the laws of war and war crimes in the body of secular international law. A third conference was planned for 1914 and later rescheduled for 1915, but it did not take place because of the start of World War I.
