Law is a system of rules recognized and enforced by the state to regulate human conduct, maintain order, and ensure justice. Every legal system derives its authority from recognized sources of law, which provide the foundation for the creation, interpretation, and application of legal rules. Among the various sources of law, legislation and judicial precedents occupy a central position in modern legal systems. While legislation represents laws formally enacted by the legislature, judicial precedents consist of legal principles established by courts through their decisions. Both sources complement each other in ensuring certainty, consistency, adaptability, and justice in the legal system. Legislation refers to laws enacted by a competent legislative authority such as Parliament or State Legislatures. It is the most important and authoritative source of law in modern democratic societies because it reflects the will of the people expressed through their elected representatives. Legislation provides clear, systematic, and comprehensive legal rules that govern various aspects of public and private life. The process of legislation generally involves several stages. A bill is introduced in the legislature, debated extensively, examined by committees where necessary, voted upon, and finally receives the assent of the President or Governor before becoming law. This process ensures democratic participation, public accountability, and careful scrutiny of proposed legal measures. Legislation may be classified into different types. Supreme legislation is enacted by a sovereign legislative body and cannot be overridden by any other authority except through constitutional procedures. Subordinate or delegated legislation is made by authorities such as government departments, local bodies, or statutory agencies under powers delegated by the legislature. Delegated legislation includes rules, regulations, notifications, orders, and by-laws framed to implement the objectives of primary legislation. Legislation possesses several important characteristics. It is written, definite, and easily accessible. Since statutes are codified, citizens can ascertain their rights and obligations with greater certainty. Legislative enactments are prospective in nature and generally apply uniformly to all persons falling within their scope. The authority of legislation derives from the Constitution, which establishes the legislative powers of Parliament and State Legislatures. One of the greatest advantages of legislation is certainty. Statutes provide clear legal standards that reduce ambiguity and promote uniform application. Individuals, businesses, and public authorities can organize their conduct according to known legal rules. Another advantage is comprehensiveness. The legislature has the capacity to enact laws covering complex social, economic, technological, and environmental issues. Through legislative action, governments can address emerging challenges such as cybercrime, environmental protection, digital privacy, consumer rights, and artificial intelligence more effectively than reliance solely on judicial decisions. Legislation also promotes democratic legitimacy. Laws enacted by elected representatives reflect public opinion, policy objectives, and social needs. Since legislators are
