Consider the following statements: 1. A bill amending the Constitution requires a prior recommendation of the President of India. 2. When a Constitution Amendment Bill is presented to the President of India, it is obligatory for the President of India to give his/her assent. 3. A Constitution Amendment Bill must be passed by both the Lok Sabha and the Rajya Sabha by a special majority and there is no provision for joint sitting. Which of the statements given above are correct?

Let's analyze the statements regarding a bill amending the Constitution: 1. A bill amending the Constitution requires a prior recommendation of the President of India: A Bill for the amendment of the Constitution (under Article 368) can be introduced in either House of Parliament without the prior recommendation of the President. This is a key distinction from certain other types of bills (e.g., Money Bills). Therefore, statement 1 is incorrect. 2. When a Constitution Amendment Bill is presented to the President of India, it is obligatory for the President of India to give his/her assent: The 24th Constitutional Amendment Act of 1971 made it obligatory for the President to give assent to a Constitution Amendment Bill, meaning the President cannot withhold assent or return the bill for reconsideration. This statement is correct. 3. A Constitution Amendment Bill must be passed by both the Lok Sabha and the Rajya Sabha by a special majority and there is no provision for joint sitting: A Constitution Amendment Bill must be passed by each House of Parliament by a special majority (i.e., a majority of the total membership of the House and a majority of not less than two-thirds of the members of that House present and voting). There is no provision for a joint sitting of both Houses to resolve a deadlock over a Constitution Amendment Bill; if one House rejects the bill or proposes amendments not acceptable to the other, the bill fails. This statement is correct.
