federal compromise, to assign other federal institutions, such as the Federal Polytechnical School (1854, the later ETH) to Zürich, and other institutions to Lucerne, such as the later SUVA (1912) and the Federal Insurance Court (1917). Other federal institutions were subsequently attributed to Lausanne (Federal Supreme Court in 1872, and EPFL in 1969), Bellinzona (Federal Criminal Court, 2004), and St. Gallen (Federal Administrative Court and Federal Patent Court, 2012). The 1999 Constitution does not mention a Federal City and the Federal Council has yet to address the matter. Thus as of 2022, no city in Switzerland has the official status either of capital or of Federal City. Nevertheless, Bern is commonly referred to as "Federal City" (, , ). Foreign relations and international institutions Traditionally, Switzerland avoids alliances that might entail military, political, or direct economic action and has been neutral since the end of its expansion in 1515. Its policy of neutrality was internationally recognised at the Congress of Vienna in 1815. Swiss neutrality has been questioned at times. In 2002 Switzerland became a full member of the United Nations. It was the first state to join it by referendum. Switzerland maintains diplomatic relations with almost all countries and historically has served as an intermediary between other states. Switzerland is not a member of the European Union; the Swiss people have consistently rejected membership since the early 1990s. However, Switzerland does participate in the Schengen Area. Many international institutions have headquarters in Switzerland, in part because of its policy of neutrality. Geneva is the birthplace of the Red Cross and Red Crescent Movement, the Geneva Conventions and, since 2006, hosts the United Nations Human Rights Council. Even though Switzerland is one of the most recent countries to join the United Nations, the Palace of Nations in Geneva is the second biggest centre for the United Nations after New York. Switzerland was a founding member and hosted the League of Nations. Apart from the United Nations headquarters, the Swiss Confederation is host to many UN agencies, including the World Health Organization (WHO), the International Labour Organization (ILO), the International Telecommunication Union (ITU), the United Nations High Commissioner for Refugees (UNHCR) and about 200 other international organisations, including the World Trade Organization and the World Intellectual Property Organization. The annual meetings of the World Economic Forum in Davos bring together business and political leaders from Switzerland and foreign countries to discuss
