The question of whether the 'right to die' is a fundamental right under Article 21 of the Indian Constitution, which guarantees the 'right to life and personal liberty,' has seen a significant evolution through judicial pronouncements.

Initial Interpretation and Evolution: Article 21 states, "No person shall be deprived of his life or personal liberty except according to procedure established by law." The Supreme Court has given a broad and expansive interpretation to the 'right to life,' extending it beyond mere animal existence to include the right to live with human dignity, quality of life, and all that makes life meaningful.

The 'Right to Die' Controversy:

1. P. Rathinam v. Union of India (1994): In this landmark case, a two-judge bench of the Supreme Court held that the 'right to life' under Article 21 included the 'right not to live a forced life.' Consequently, the Court struck down Section 309 of the Indian Penal Code (IPC), which criminalized the attempt to commit suicide, deeming it unconstitutional. The rationale was that if one has a right to live, one also has a right not to live.

2. Gian Kaur v. State of Punjab (1996): A five-judge Constitution Bench of the Supreme Court reconsidered the Rathinam judgment. It explicitly overruled P. Rathinam, holding that the 'right to life' under Article 21 does not include the 'right to die.' The Court clarified that the 'right to life' is a natural right, while suicide is an unnatural termination of life and inconsistent with the concept of the right to life. It upheld the constitutional validity of Section 309 IPC, stating that the 'right to life' is a positive right and cannot be interpreted to include the right to end one's life. The Court distinguished between the right to die and the right to die with dignity, suggesting that the latter might be part of Article 21.

Right to Die with Dignity (Passive Euthanasia): While the right to commit suicide was rejected, the concept of 'right to die with dignity' for terminally ill patients gained judicial attention.

3. Aruna Shanbaug v. Union of India (2011): This case involved a nurse who had been in a persistent vegetative state for decades. The Supreme Court, while reiterating that active euthanasia is illegal, allowed 'passive euthanasia' (withdrawal of life support) for terminally ill patients in specific circumstances. It laid down detailed guidelines for the procedure, requiring court approval and a decision by a 'next friend' or parents, subject to medical board assessment. This judgment implicitly recognized a limited 'right to die with dignity' in specific, extreme medical conditions.

4. Common Cause (A Regd. Society) v. Union of India (2018): A five-judge Constitution Bench of the Supreme Court finally recognized the 'right to die with dignity' as a fundamental right under Article 21. The Court held that an individual has the right to refuse medical treatment, including the right to withhold or withdraw life support, in cases of terminal illness or irreversible vegetative state. Crucially, it allowed for 'living wills' or 'advance medical directives,' enabling individuals to make decisions about their medical treatment in advance, to be implemented if they become terminally ill and unable to communicate. The Court laid down comprehensive guidelines for the execution and implementation of such advance directives and the procedure for passive euthanasia, emphasizing strict safeguards and judicial oversight.

Conclusion: In summary, the 'right to die' (meaning the right to commit suicide) is not a fundamental right under Article 21. However, the 'right to die with dignity' through passive euthanasia and advance medical directives for terminally ill patients has been recognized as a fundamental right, subject to stringent judicial and medical safeguards.
