The legal system is built upon various sources of law that establish rules, principles, and regulations governing society. These sources provide authority and legitimacy to legal decisions, ensuring consistency, fairness, and justice. Legal sources of law can be classified into primary and secondary sources, each playing a vital role in the formation and interpretation of law. This article explores the key legal sources of law, their significance, and their role in modern legal systems.
1. Primary Sources of Law
Primary sources of law are the fundamental legal documents and decisions that directly establish legal principles.
