Sources of law are the origins from which legal rules and principles are derived. The primary sources include statutes, which are laws enacted by legislative bodies, and case law, which consists of judicial decisions that interpret and apply these statutes. Additionally, administrative regulations created by government agencies also serve as important sources of law. Another significant source is constitutional law, which establishes the fundamental principles and framework of a government. International law can also influence domestic law, especially in countries that recognize treaties and agreements. Together, these sources create a comprehensive legal system that governs society.
