The Swiss legal system is a civil law system with roots in the German and French legal traditions. The organization of the Swiss legal and court systems is characterized by Switzerland's federal structure. The power to legislate in civil law (including civil procedure law) and penal law (including criminal procedure law) matters is attributed to the Federation. Hence the core legal rules relating to libel law are codified in federal statutes. Yet the 26 cantons, the federal states of the Swiss Confederation, remain competent to legislate in administrative law matters and in the organization of their courts and administrative authorities. According to the Federal Civil Procedure Code of December 19, each canton, in principle, may autonomously organize its courts. However, each canton is required to establish at least one court of first instance and one of second instance hearing both criminal and civil law cases. In addition, each canton has one administrative court. Decisions of the cantonal courts of second instance and the cantonal administrative courts may be appealed to the Swiss Federal Supreme Court.
