Part XX of the Constitution of India deals exclusively with the amendment procedure under a single article.
- Constitutional Article: Article 368 contained in Part XX (Power of Parliament to amend the Constitution and procedure therefor).
- Introduction of Bill: An amendment bill can be introduced in either House of Parliament (Lok Sabha or Rajya Sabha) and NOT in the state legislatures.
- Prior Permission: The bill can be introduced either by a minister or by a private member and does not require prior recommendation of the President.
- Passing Requirements: The bill must be passed in each House by a special majority, i.e., a majority of the total membership of the house and a majority of two-thirds of the members present and voting.
- No Joint Sitting: There is no provision for a joint sitting of the two Houses if there is a deadlock over a constitutional amendment bill.
- Presidential Assent: The President MUST give assent to the constitutional amendment bill. The 24th Constitutional Amendment Act of 1971 made it obligatory for the President to give assent.
