Amendment of the Constitution of India in the context of "Basic structure doctrine"

The Supreme Court of India is the supreme judicial authority and the highest court of the Republic of India. It is the final court of appeal for all civil and criminal cases in India. It also has the power of judicial review. The Supreme Court, which consists of the chief justice of India and a maximum of fellow 33 judges, has extensive powers in the form of original, appellate and advisory jurisdictions.

As the apex constitutional court, it takes up appeals primarily against verdicts of the High Courts of various states and tribunals. As an advisory court, it hears matters which are referred by the president of India. Under judicial review, the court invalidates both ordinary laws as well as constitutional amendments as per the basic structure doctrine that it developed in the 1960s and 1970s.

His Holiness Kesavananda Bharati Sripadagalvaru & Ors. v. State of Kerala & Anr. (Writ Petition (Civil) 135 of 1970), also known as the Kesavananda Bharati judgement, was a landmark decision of the Supreme Court of India that outlined the basic structure doctrine of the Indian Constitution. The case is also known as the Fundamental Rights Case. The court in a 7-6 decision asserted its right to strike down amendments to the constitution that were in violation of the fundamental architecture of the constitution.

Justice Hans Raj Khanna argued that the Constitution possesses a basic structure of constitutional principles and values. The Court partially cemented the prior precedent Golaknath v. State of Punjab, which held that constitutional amendments through Article 368 were subject to fundamental rights review, but only if they could affect the 'basic structure of the Constitution'. At the same time, the Court also upheld the constitutionality of the first provision of Article 31-C, which implied that laws seeking to implement the Directive Principles, which do not affect the 'Basic Structure,' shall not be subjected to judicial review.
