National law refers to the legal system and regulations that govern a specific country. It encompasses statutes, regulations, and case law created by the country's legislative bodies, such as Congress in the United States or Parliament in the United Kingdom. National law is designed to maintain order, protect individual rights, and promote justice within the nation. National law can vary significantly from one country to another, reflecting each nation's unique culture, history, and values. It is distinct from international law, which governs relations between countries. National law is enforced by various institutions, including courts, police, and government agencies.
