Supreme Court of India – Complete Guide for UPSC (Structure, Powers, Jurisdiction, Landmark Judgements, Basic Structure Doctrine)

The Supreme Court of India is the highest judicial authority in the country and the guardian of the Constitution. It acts as the final interpreter of the Constitution and protects the fundamental rights of citizens.

The Supreme Court was established on 26 January 1950 after the Constitution of India came into force. It replaced the Federal Court of India and the Judicial Committee of the Privy Council which earlier served as the highest courts of appeal.

The provisions relating to the Supreme Court are mentioned in Part V of the Constitution (Articles 124 to 147).


Importance of the Supreme Court in Indian Democracy

The Supreme Court plays a crucial role in maintaining the democratic structure of India. It ensures that the Constitution remains supreme and that the government functions within constitutional limits.

  • Guardian of the Constitution
  • Protector of Fundamental Rights
  • Final court of appeal
  • Interpreter of the Constitution
  • Ensures rule of law

Historical Background of the Supreme Court

Before independence, India had the Federal Court established in 1937. Appeals from the Federal Court were sent to the Privy Council in London.

After independence, the Constitution of India created a unified judicial system with the Supreme Court at the top.

On 26 January 1950, the Supreme Court began functioning as the highest court of the land.

Originally the court had 8 judges. Today the sanctioned strength is:

The judges of the Supreme Court are appointed by the President of India.

Currently the appointment follows the Collegium System.

The doctrine was established in the historic Kesavananda Bharati Case (1973).
