Parliament had added the Ninth Schedule to the Constitution through the very first constitutional amendment in 1951 as a means of immunizing certain laws against judicial review. Under the provisions of Article 31, which themselves were amended several times later, laws placed in the Ninth Schedule could not be challenged in a court of law on the ground that they violated the fundamental rights of citizens. The protective umbrella covered more than 250 laws passed by state legislatures with the aim of regulating the size of land holdings and abolishing various tenancy systems. The Ninth Schedule was created with the primary objective of preventing the judiciary – which upheld the citizens' right to property on several occasions – from derailing the Nehru government's agenda for land reform, but it outlived its original purpose.
