Concept:
The term "Statute" refers to a formal written enactment of a legislative authority that governs a country, state, or city. In the hierarchy of laws, statutes are primary legislation, as opposed to secondary or delegated legislation (like rules and regulations).
Step 1: Understanding the Legislative Process.
In a democracy, the power to make laws is vested in the Legislature (Parliament at the central level and Legislative Assemblies at the state level). When a "Bill" is passed by these houses and receives the assent of the Head of State (President or Governor), it becomes an Act or a Statute.
$\text{Bill} \xrightarrow{\text{Passage + Assent}} \text{Statute/Act}$
Step 2: Distinguishing from other bodies.
• Board of Directors: They pass resolutions or bylaws for a specific company, not laws for the public.
• Registered Associations: They have internal rules (Articles of Association), but no sovereign power.
• Government Departments: They issue "Notifications" or "Rules" under the authority of a statute, but they do not enact the statute itself.
Step 3: Conclusion.
A statute is the highest expression of the will of the people through their elected representatives. Therefore, it is specifically a law enacted by the legislative body.
