To maintain a healthy democracy, the government of Sri Lanka is structured into three main organs: the Legislature, the Executive, and the Judiciary.
This system, known as the Separation of Powers, is designed to prevent the concentration of authority in a single entity, ensuring accountability, fairness, and good governance across the nation.

1. The Legislature: The Law-Making Body
The Legislature is the primary organ responsible for drafting and enacting laws. In Sri Lanka, this power is held by Parliament, which serves as the supreme representative body of the people.
- Composition: It consists of Members of Parliament (MPs) who are chosen through democratic elections.
- Primary Duty: Beyond making laws, Parliament also maintains control over public finance and national budgets.
2. The Executive: Implementation and Enforcement
The Executive branch ensures that the laws passed by the Legislature are implemented and enforced effectively.
- Leadership: This branch is led by the President of Sri Lanka, who is directly elected by the citizens as the Head of State and Government.
- Structure: Executive power is exercised by the President, the Cabinet of Ministers, and various government departments or institutions.
3. The Judiciary: Interpretation and Justice
The Judiciary serves as the independent guardian of the law. Its primary role is to interpret legislation and deliver justice to ensure the rule of law is upheld.
- Hierarchy of Courts: Judicial power is exercised through a system of courts, with the Supreme Court at the apex, followed by the Court of Appeal and various lower courts.
- Independence: The judiciary functions autonomously to remain free from political influence, ensuring every citizen receives a fair trial and that fundamental rights are protected.
