The Swiss legal system is based on civil law principles, primarily influenced by the Swiss Federal Constitution. It consists of federal, cantonal, and municipal laws, with the federal government handling areas like criminal law and immigration, while cantons manage local matters such as education and health. Judicial authority in Switzerland is divided among various courts, including the Federal Supreme Court, which serves as the highest court. The system emphasizes the rule of law, ensuring that laws are applied equally to all citizens, and it allows for a high degree of legal certainty and protection of individual rights.
