When a patient can refuse life-saving treatment

An adult patient of sound mind has a near-absolute right to refuse medical treatment, including treatment that is necessary to save life. The right has two doctrinal anchors. The first is the common-law tort of battery — every touching of the body without consent is actionable trespass to the person, and a surgeon who operates without consent or a hospital that forces a transfusion on a competent objector is liable in damages just as a stranger who strikes the patient on the street would be. The second is the constitutional guarantee in Article 21 of the Constitution of India. The Supreme Court in Common Cause (A Regd Society) v Union of India, (2018) 5 SCC 1 — the five-judge Constitution Bench that recognised the right to die with dignity and authorised advance medical directives — read the right to refuse treatment as a facet of the right to life itself, building on Aruna Ramchandra Shanbaug v Union of India, (2011) 4 SCC 454 and distinguishing Gian Kaur v State of Punjab, (1996) 2 SCC 648. Justice K S Puttaswamy v Union of India, (2017) 10 SCC 1 supplied the bodily-autonomy-as-privacy frame that Common Cause drew on. This guide sets out the doctrinal anchors, the emergency-doctrine exception, the procedure for a competent adult who refuses life-saving treatment, and the January 2023 simplification of the advance-directive regime.

The proposition that a competent adult patient can decline medical treatment — even where the refusal will kill the patient — is one of the older common-law principles, restated by Justice Cardozo in Schloendorff v Society of New York Hospital, 105 NE 92 (NY 1914): "Every human being of adult years and sound mind has a right to determine what shall be done with his own body; and a surgeon who performs an operation without his patient's consent commits an assault, for which he is liable in damages." Indian law absorbed the same rule through the law of torts — the wrong of battery in trespass to the person — and added a constitutional dimension through the right to life in Article 21. The Supreme Court Constitution Bench in Common Cause (A Regd Society) v Union of India, (2018) 5 SCC 1 framed it directly: a competent patient's refusal of treatment is "an expression of the right to self-determination" that "must be respected by the doctor". This article sets out how that right works in practice, and where it ends.

The two doctrinal anchors — battery and Article 21

Every medical intervention — from a swab to a thoracic surgery — is a touching of the body. At common law a touching without consent is actionable as the tort of battery, the central wrong in trespass to the person. The standard texts and the Indian commentary on trespass to the person treat consent as the operative justification for every clinical contact: the absence of consent converts even a beneficial intervention into a civil wrong. Battery is actionable per se — the patient need not prove physical harm to recover damages; the violation of bodily integrity is itself the gist of the action. The treating doctor's professional judgement that the intervention was necessary is, of itself, no defence. Consent is the defence.

The same principle is replicated in the criminal-law architecture. Sections 26 and 27 of the Bharatiya Nyaya Sanhita, 2023 [Sections 88, 89 and 92 of the Indian Penal Code, 1860] limit the criminal liability of a person who acts in good faith for the benefit of another — but the protection is qualified, in the case of an adult of sound mind, by the requirement of consent. Acts of hurt or grievous hurt by a surgeon are not punishable under Sections 115, 117 or 125 of the Bharatiya Nyaya Sanhita, 2023 [Sections 319, 320, 321 and 322 of the Indian Penal Code, 1860] precisely because the patient's consent operates as a defence; without consent the protection of Section 26 falls away.

The constitutional dimension is more recent. The right to life and personal liberty in Article 21 has been read since Maneka Gandhi as a substantive guarantee that controls every State and State-instrumentality interaction with the person. The Supreme Court in Justice K S Puttaswamy v Union of India, (2017) 10 SCC 1 elevated decisional autonomy and bodily integrity to a constitutionally protected privacy interest — every individual is "the ultimate decision-maker on matters concerning her body". In Common Cause (A Regd Society) v Union of India, (2018) 5 SCC 1 the Constitution Bench applied that frame to medical treatment. The court held that the right to live with dignity under Article 21 includes the right to refuse medical treatment, and that a competent patient's contemporaneous refusal — and, in defined circumstances, a prior written refusal in the form of an advance directive — is binding on the treating physician.

The Common Cause framework — what the Constitution Bench decided

The Constitution Bench in Common Cause v Union of India, (2018) 5 SCC 1 held four propositions on the right to refuse treatment that now constitute the operative law in India.

First — the right to die with dignity is part of Article 21. The right to live with dignity, the court held, includes "the smoothening of the process of dying in case of a terminally ill patient or a person in PVS with no hope of recovery". Withholding or withdrawing treatment in such cases is "not euthanasia" in the criminal sense — it is "the recognition of the inviolability of the patient's right to bodily integrity and self-determination".

Second — passive euthanasia is permissible. Building on Aruna Ramchandra Shanbaug v Union of India, (2011) 4 SCC 454 — where a two-judge bench had laid down a procedure for withdrawal of life-support in a permanent vegetative state — the Constitution Bench held that passive euthanasia (the withdrawal or withholding of life-sustaining treatment) is legally permissible, subject to safeguards. Active euthanasia — the administration of a lethal substance — remains a criminal offence under the Bharatiya Nyaya Sanhita, 2023 [Indian Penal Code, 1860].

Third — advance medical directives are valid. The court for the first time recognised the legal validity of a "living will" — a written instrument by which an adult of sound mind specifies, while competent, the medical treatment he or she wishes to receive (or refuse) at a future point when he or she is no longer competent to communicate. The court laid down a detailed procedure for the execution, custody, activation and review of advance directives — substantially modified by the same court in January 2023, on which see the discussion at the end of this article and the cross-reference to the companion guide.

Fourth — Gian Kaur is distinguished, not overruled. The court in Gian Kaur v State of Punjab, (1996) 2 SCC 648 had held that the right to life under Article 21 does not include the right to die — overruling the contrary holding of the two-judge bench in P Rathinam v Union of India, (1994) 3 SCC 394, which had read down Section 309 of the Indian Penal Code (attempt to commit suicide). The Constitution Bench in Common Cause distinguished Gian Kaur by drawing the doctrinal line between (a) suicide — an active act ending an otherwise healthy life — and (b) refusal of treatment or withdrawal of life support in a terminal or permanent-vegetative case — a passive non-intervention in the natural process of dying. Refusal of treatment is not suicide; the patient who refuses dialysis or chemotherapy or a ventilator dies of the underlying disease, not of the refusal.

The contemporaneous-refusal scenario — adult, conscious, competent

The simplest case is the adult patient who is conscious, mentally competent, and in real time refuses a recommended treatment — a Jehovah's Witness refusing a blood transfusion, a terminal cancer patient declining further chemotherapy, an end-stage renal-failure patient declining dialysis, a patient refusing amputation of a gangrenous limb. The legal position is settled. The English Court of Appeal in Re T (Adult: Refusal of Treatment), [1992] 4 All ER 649 (CA) — frequently cited in Indian commentary on consent — captured the rule: "An adult patient who suffers from no mental incapacity has an absolute right to choose whether to consent to medical treatment, to refuse it, or to choose one rather than another of the treatments being offered. This right of choice is not limited to decisions which others might regard as sensible. It exists notwithstanding that the reasons for making the choice are rational, irrational, unknown or even non-existent."

Three requirements anchor the rule. The patient must be (a) of full age — an adult, and the precise age of consent for medical treatment in India is the subject of evolving jurisprudence around the Mental Healthcare Act 2017 and the POCSO regime, but for ordinary adult patients the eighteen-year line is settled; (b) of sound mind — capable of comprehending the nature and consequences of the proposed treatment and the consequences of refusing it; and (c) acting voluntarily — free of duress or undue influence from family, hospital staff or other actors. Where all three are satisfied, the patient's refusal is conclusive, and the treating doctor who proceeds in the face of refusal exposes himself or herself to (i) a civil action for battery, (ii) disciplinary proceedings under the regulations of the National Medical Commission or the State Medical Council, and (iii) potential criminal liability for hurt under the Bharatiya Nyaya Sanhita, 2023 [Indian Penal Code, 1860].

The Supreme Court in Samira Kohli v Dr Prabha Manchanda, (2008) 2 SCC 1 — though primarily addressed to the scope of informed consent in a planned surgical setting — anchored the same principle from the consent side: a surgeon who exceeds the scope of the consent given (in that case, performing a hysterectomy and bilateral salpingo-oophorectomy where consent was only for a diagnostic laparoscopy) acts in trespass and is liable in damages. The flip side of the proposition is the right to refuse: every treatment exceeding what the patient has consented to is, in principle, a battery.

The emergency-doctrine exception

The exception that most often arises in practice is the emergency. Where a patient is brought to a hospital unconscious or otherwise incapable of communicating consent — a road-accident victim, a patient in cardiac arrest, an overdose case — the treating doctor is legally permitted to render life-saving treatment without contemporaneous consent. The doctrine is generally framed as one of "implied consent" or, more accurately in Indian law, of "necessity": Section 26 of the Bharatiya Nyaya Sanhita, 2023 [Section 88 IPC] and Section 27 [Section 92 IPC] together protect a doctor who acts in good faith for the benefit of an unconscious patient where consent cannot be obtained. The relevant Indian-tort-law authority on consent and surgery on an unconscious person describes the position succinctly — "performing the operation of an unconscious person by a competent surgeon to save the former's life" is a lawful use of force and not a battery.

The exception is, however, exactly that — an exception. Three limits operate. First, it applies only where the patient is genuinely incapable of communicating consent; it cannot be invoked to override a conscious patient who is refusing. Second, it is confined to the treatment necessary to meet the immediate emergency; elective or non-urgent treatment requires consent in the ordinary way. Third, it does not override a known and valid advance directive. If the unconscious patient has a recorded advance directive that refuses the specific treatment in question, the directive controls (subject to the verification procedure laid down in Common Cause and as modified in January 2023).

The Supreme Court in Parmanand Katara v Union of India, (1989) 4 SCC 286 — addressed in the companion guide to emergency-admission obligations — held that every doctor has a professional and constitutional duty to render immediate medical aid in an emergency without waiting for procedural compliance. That ruling sits comfortably with the emergency-doctrine exception to the consent rule: the doctor's emergency duty to treat is matched by the law's recognition that consent cannot always be obtained in an emergency, and the doctor is protected when treating in good faith.

The refusal-by-proxy problem — surrogate decision-making

The harder case is the patient who has, by the time the question of treatment arises, lost the capacity to refuse — a patient in a permanent vegetative state, a patient with advanced dementia, a patient who has been in an irreversible coma for years. Two routes are now available under Indian law to respect what would have been the patient's autonomous choice.

The Aruna Shanbaug procedure for incompetent patients without an advance directive. The Supreme Court in Aruna Ramchandra Shanbaug v Union of India, (2011) 4 SCC 454 — addressing the case of a nurse who had been in a permanent vegetative state for thirty-seven years at the time of the judgment — held that withdrawal of life support from a patient in PVS is lawful, subject to (a) a decision by the close family members in consultation with the treating doctors, and (b) approval by the jurisdictional High Court under Article 226. The Constitution Bench in Common Cause restated and refined this route — the family-and-medical-board procedure remains the operative pathway for incompetent patients who do not have an advance directive.

The Common Cause advance-directive procedure. Where the patient has executed a valid advance directive while competent, the procedure for activation and implementation is governed by Common Cause (2018) as modified by the Supreme Court on 24 January 2023 in Common Cause v Union of India, MA 1699/2019 in WP (Civil) 215/2005. The procedure — execution before two attesting witnesses and authentication by a Judicial Magistrate of First Class, with the modified 2023 framework dispensing with several of the bureaucratic steps in the original 2018 ruling — is the subject of the companion guide.

The Mental Healthcare Act 2017 — capacity, advance directives in mental-illness

A specialised statutory regime applies where the patient has a mental illness. The Mental Healthcare Act, 2017 recognises a person's right to refuse mental-illness treatment (subject to safeguards for supported decision-making and for involuntary admission where prescribed). Section 5 of the Act allows a person to make an advance directive specifying how to be treated, and how not to be treated, for a mental illness; Sections 88 to 98 govern admission and discharge. The Act displaces the general common-law and Article 21 rules in the mental-illness context — but only there. For physical-illness treatment of a person with mental illness who retains decision-making capacity for the physical illness in question, the ordinary Common Cause / Article 21 / battery framework applies. The interaction between the two regimes is addressed in the companion article on the Mental Healthcare Act 2017 admission and discharge procedure.

Other domains where consent and refusal operate

Beyond ordinary medical and surgical treatment, three statutory regimes turn squarely on consent and the right to refuse.

Organ donation. The Transplantation of Human Organs and Tissues Act, 1994 — Sections 3 and 9 in particular — controls the harvesting of organs and tissues, and turns on the donor's written consent. The right to refuse organ donation, including after death, is operative; consent of the donor (or, where statutorily permitted, of near relatives in defined circumstances) is the precondition for any harvesting.

Sterilisation and reproductive procedures. The Medical Termination of Pregnancy Act, 1971 and the Surrogacy (Regulation) Act, 2021 turn on the woman's written consent, and the Supreme Court has repeatedly held that the woman's reproductive autonomy is part of the personal-liberty guarantee in Article 21.

Clinical trials and research. The New Drugs and Clinical Trials Rules, 2019 contain a detailed informed-consent framework. A participant in a clinical trial can refuse to continue at any stage; the right to withdraw is unconditional.

Common refusal scenarios in Indian hospitals — what is, and is not, decisive

Five recurring scenarios in Indian hospitals are worth distinguishing.

Discharge against medical advice. A competent adult patient who chooses to leave the hospital against medical advice is exercising the same right to refuse treatment. The hospital's role is limited to (a) explaining the medical consequences, (b) recording the refusal in writing — the DAMA (Discharge Against Medical Advice) form — and (c) discharging the patient. The DAMA form is evidentiary, not a waiver of the hospital's continuing duty of care while the patient remains on premises.

Refusal by relatives where the patient is competent. A relative — spouse, parent, adult child — has no legal authority to override a competent adult patient's refusal or consent. The patient is the decision-maker. Hospitals routinely treat the relative as the decision-maker for convenience; that practice has no legal foundation when the patient is conscious and competent.

Religious refusal of blood transfusion. The Jehovah's Witness scenario — a competent adult who refuses blood for religious reasons even where transfusion is necessary to save life — is the textbook application of Re T and the Common Cause autonomy frame. The refusal is binding. The court of appeal in Re T qualified the rule only where the apparent refusal was the product of duress or undue influence by a third party, in which case the court can intervene to set aside the refusal; the underlying autonomy principle is unaffected.

Minors and treatment refusal. The autonomy rule applies in its full strength only to adults of sound mind. For minors, consent is given by the parent or guardian, with the High Court's parens-patriae jurisdiction available where the parent's decision is harmful to the child. The age at which a minor's own consent (or refusal) becomes operative is a subject of ongoing jurisprudence — Indian commentary is gravitating to the "Gillick competence" standard from the English House of Lords, but the Indian position is not yet settled in a Supreme Court ruling.

The mentally-ill patient with capacity for the specific decision. Decision-making capacity is decision-specific, not status-based. A patient who lacks capacity for a complex surgical decision may have capacity for a simple one; a patient with a diagnosed mental illness may have full capacity for a physical-illness decision. The Mental Healthcare Act 2017 codifies this functional approach to capacity.

The January 2023 simplification — what changed

The 2018 Constitution Bench in Common Cause laid down a detailed advance-directive procedure that, in practice, almost no one used. The Supreme Court in Common Cause v Union of India, MA 1699/2019 in WP (Civil) 215/2005, order dated 24 January 2023 modified the procedure substantially to make it practical. The modified procedure: (a) the directive may be signed before two attesting witnesses and notarised by a Notary or a gazetted officer, and authenticated by a Judicial Magistrate of First Class — the requirement that the directive be countersigned by the JMFC at the execution stage was retained but other bureaucratic steps were rationalised; (b) the timelines for the primary and secondary medical-board procedures for withdrawal of life support were tightened; (c) the role of the Collector / District Officer was clarified. The detailed procedure is the subject of the companion guide on the living will.

The doctrinal map — autonomy, dignity, the right to die naturally

The Indian right to refuse medical treatment now rests on three doctrinal pillars. The tort of battery in trespass to the person supplies the common-law cause of action; consent is the operative defence and the absence of consent the actionable wrong. Article 21 of the Constitution supplies the constitutional guarantee — the right to live with dignity, read by the Constitution Bench in Common Cause to include the right to refuse treatment and, in defined circumstances, the right to die with dignity. The bodily-autonomy reading of privacy in Puttaswamy supplies the cross-cutting frame — every individual is the ultimate decision-maker on matters concerning the body.

The unresolved questions sit at the edges. The line between passive non-intervention (lawful) and active hastening of death (unlawful, under Section 103 of the Bharatiya Nyaya Sanhita, 2023 [Section 302 IPC]) is doctrinally settled but practically contested in palliative-care settings. The age and capacity thresholds for minors and mentally-ill patients are evolving. The duty of the State to fund and resource respect for advance directives — the operational reality that the January 2023 procedure presumes — is patchy across States.

For the competent adult patient, however, the position is clear and has been clear for more than a century at common law and since Common Cause in 2018 in Indian constitutional law: a patient of sound mind has the right to refuse the touch of the State, the hospital, and even the doctor who would save her life. The refusal need not be reasonable, or wise, or supported by family. It is the patient's right.
