This judgment of basic structure doctrine in the case of Kesavananda Bharathi Sripadagalvaru & Ors v State of Kerala & Anr (1973) was a landmark judgement to determine the change of subsequent constitutional amendments in the country of India. It holds that while the Parliament can alter the Constitution, the fundamental framework or Character of Constitution, meaning the principles of democracy, secularism, federal structure, and the rule of law cannot be removed by the Parliament.

This doctrine restricts the Parliament which is advantageous to preserve the pure form of the constitution. It also helps the judiciary to scrutinize the amendments and set them aside if they are against the spirit of the Constitution, as in the case of Minerva Mills v. Union of India (1980) connected with the 42nd Amendment.

Consequently, as per the basic structure, the doctrine shields the rights from gradual erosion by amendments while maintaining the Constitution’s stability. It also maintains a proper balance with the legislative branch to ensure that one does not encroach on the powers of the other and dilute key constitutional provisions. Altogether, the basic structure doctrine has come out as a very effective tool in the quest to safeguard the framework of the constitution in India.
