The Ninth Schedule was introduced by the First Constitutional Amendment Act, 1951 to protect certain laws, particularly those related to land reforms, from judicial review.

Prime Minister Jawaharlal Nehru introduced the Constitution (First Amendment) Bill in the Lok Sabha in 1951. This amendment aimed to safeguard progressive socio-economic legislation from being struck down by courts on the grounds of violating fundamental rights, particularly the right to property under Article 31 (which was later repealed by the 44th Amendment in 1978).
