The Federal Constitution adopted in 1848 is the legal foundation of the modern federal state. It is among the oldest constitutions in the world. A new Constitution was adopted in 1999, but did not introduce notable changes to the federal structure. It outlines basic and political rights of individuals and citizen participation in public affairs, divides the powers between the Confederation and the cantons and defines federal jurisdiction and authority. There are three main governing bodies on the federal level: the bicameral parliament (legislative), the Federal Council (executive) and the Federal Court (judicial).
