1. Constitutional provision: Article 67(a), in Part V of the Constitution of India, provides that the Vice-President may resign the office by writing under their hand addressed to the President. Under Article 67, the normal term of office is five years from the date of entering office. 2. Constitutional amendments and statutory law: Article 67(a) directly governs resignation, and no separate parliamentary statute is required for this specific constitutional procedure. Under Article 67(b), the Vice-President may be removed by a resolution of the Rajya Sabha passed by a majority of all the then members of the House and agreed to by the Lok Sabha. At least 14 days' notice of the intention to move the resolution is required. 3. Judicial decisions and legal interpretation: The answer follows directly from the express constitutional text. Article 67(a) specifies a written resignation addressed to the President; it does not state that the resignation becomes effective only upon the President's acceptance. Claiming that presidential acceptance is constitutionally required under this clause would therefore be inaccurate. Related provisions include Article 64, which makes the Vice-President the ex-officio Chairman of the Rajya Sabha, and Article 65, which provides for the Vice-President to act as President in specified circumstances.
