According to Article 368 of the Indian Constitution, a Constitutional Amendment Bill must be passed by both the Lok Sabha (House of the People) and Rajya Sabha (Council of States) by a two-thirds majority of the members present and voting.
Important constitutional amendments include the 42nd Amendment (1976) – known as the "Mini Constitution", and the 73rd and 74th Amendments for Panchayati Raj and Municipalities.
The Basic Structure Doctrine, laid down in the Kesavananda Bharati case (1973), restricts Parliament from altering the basic structure of the Constitution.
After passage, the bill requires presidential assent to become an amendment to the Constitution.
No joint sitting is allowed for Constitutional Amendment Bills (unlike ordinary bills under Article 108).
