1. About this lesson

This lesson explains why we need a judiciary, the structure of courts in India, the role of the Supreme Court, and special features like PIL and Lok Adalats.

2. Why we need a judicial system

The judiciary:

  • administers justice and settles disputes — between citizens, between a citizen and the government, and between two state governments,
  • interprets the laws,
  • protects Fundamental Rights, and
  • acts as the guardian of the Constitution.

3. Structure of the courts

India has a single, integrated three-tier court system:

LevelCourt
Highestthe Supreme Court (at New Delhi) — the highest and final court
Statethe High Courts (e.g. Punjab, Haryana and Chandigarh share a common High Court)
District / localthe subordinate and district courts

4. The Supreme Court and its powers

  • The Supreme Court is the highest and final judicial tribunal of India.
  • Under its original jurisdiction, disputes between states come directly to it.
  • Judicial review lets the courts examine whether a law is constitutional.
  • Public Interest Litigation (PIL) — introduced in India by the Supreme Court — lets any citizen approach the court for a matter of public interest.

5. Lok Adalat

  • A Lok Adalat ("people's court") provides speedy and cheap justice; it settles disputes in the language of the people, presided over by a retired judge with a lawyer and a social worker.

8. Common mistakes

  • Mistake: Calling the High Court the highest court. Fix: The Supreme Court is the highest and final court; the High Court is the highest state court.
  • Mistake: Thinking PIL was created by Parliament. Fix: PIL was introduced by the Supreme Court.
  • Mistake: Confusing original and appellate jurisdiction. Fix: Original = cases heard first (e.g. state disputes); appellate = appeals from lower courts.
