A terminally ill patient, who is eighty years old, requests his doctor to give him a lethal injection, so that he may die peacefully. The doctor administers the injection which results in death of the patient. Is doctor guilty of some offence under the Indian Penal Code?

The Central Legal Question: Consent as a Shield

The instinctive moral response to the problem is to say that the patient asked for death, the doctor acted out of compassion, and no punishment should follow. This argument finds its legal expression in Exception 5 to Section 300 IPC, reproduced verbatim in Exception 5 to Section 101 BNS, which states:

"Culpable homicide is not murder when the person whose death is caused, being above the age of eighteen years, suffers death or takes the risk of death with his own consent."

On the face of it, this exception appears to offer the doctor a complete defence: the patient was well above eighteen years of age, he was of sound mind, and he expressly requested death. Both the intention to die and the request for assistance were clearly his own.

However, the exception does not exonerate the offender entirely. It does not make the killing lawful. What it does is reduce the offence from murder to culpable homicide not amounting to murder. The doctor, in other words, does not escape criminal liability altogether. What the exception achieves is to lower the category of crime and the severity of the punishment. The killing remains unlawful; it is simply not the gravest form of unlawful killing.

This is the foundational rule: in India, euthanasia — the deliberate killing of a person at their own request — is illegal and constitutes culpable homicide not amounting to murder under Section 100 read with Exception 5 to Section 101 of the BNS, corresponding to Section 299 read with Exception 5 to Section 300 of the IPC.

The Rationale: Why Consent Cannot Authorise Death

The reason the law refuses to treat consent as a complete exoneration goes to the very bedrock of the social contract. A man's life is not merely his own possession to dispose of at will. It belongs, in a sense, equally to his family, his community, and the State. The social philosopher's argument finds its legal expression in the Code itself. The framers of the IPC, including Macaulay himself, explicitly addressed the sentiment of mercy killing with great candour. They acknowledged that the motives behind such killings are "generally far more respectable than those which prompt men to the commission of murder" — the soldier who mercifully ends the suffering of a dying comrade, the friend who supplies a sedative to a person in lingering agony, the dutiful child who helps a terminally ill parent find peace. Yet, they concluded, the state of the law does not permit private individuals to arrogate to themselves the decision of when another human being's life should end.

The consequence of accepting consent as a complete defence, the drafters feared, would be to open an enormous and dangerous door — one that could be exploited under the guise of mercy to settle matters of inheritance, personal grievance, or convenience. The law therefore takes a middle path: it acknowledges the compassionate motive by reducing the offence from murder to culpable homicide, but it does not overlook the taking of human life.

In Dasrath Paswan v. State of Bihar (AIR 1958 Patna 190), a young man who killed his wife at her own request as part of a suicide pact was tried for murder. The wife was above eighteen years of age, and her consent was free and voluntary — she had spread a mat on the floor and lay down quietly in full knowledge and acquiescence. The Patna High Court gave the benefit of Exception 5 to Section 300 IPC and held that the act was culpable homicide not amounting to murder, punishable under Section 304 Part I IPC. The exception applied precisely because the consent was real, uncoerced, and fully informed. This case is the clearest judicial endorsement of the rule that consent reduces the offence but does not nullify it.

Applying Exception 5: The Conditions That Must Be Met

For Exception 5 to Section 101 BNS (Exception 5 to Section 300 IPC) to apply, three conditions must be established:

First, the person who consented to death must have been above eighteen years of age. In the problem, the patient is eighty years old — this condition is manifestly satisfied.

Second, the consent must have been "free and voluntary", and not given under fear or under a misconception of fact. This is where Section 90 IPC (reproduced as Section 27 BNS) becomes critical. Section 90 provides that consent is not valid if it is given under fear of injury, or under a misconception of fact, or if the consenting person was intoxicated, or of unsound mind. In Poonai Fattemah v. Emperor (1869), a snake-charmer persuaded his victim to allow himself to be bitten by a poisonous snake, assuring him that he had the power to cure snake bites by charms. The victim consented, and he died. The consent was held to be vitiated because it was obtained through misrepresentation — the victim consented under a misconception of fact induced by the accused's fraud. The accused was held guilty of murder, not the lesser offence. In the problem before us, however, there is no fraud, no fear, and no misconception — the patient is an elderly, terminally ill person who understands the nature and gravity of his own condition and freely asks for death. His consent is real and valid.

Third, the consenting person must be of sound mind, capable of giving a meaningful consent. A terminal illness, however painful and however close to death, does not of itself strip a person of mental competence. If the eighty-year-old patient is of sound mind and rationally communicating his wish to die, his consent meets the legal requirement.

All three conditions being satisfied, Exception 5 applies. The doctor's act falls out of the definition of murder and into the realm of culpable homicide not amounting to murder.

Active Euthanasia vs. the Hippocratic Oath: The Doctor's Special Position

But there is a further dimension to the problem that must not be overlooked. The doctor is not an ordinary private person. He is a medical professional bound by the Hippocratic Oath and the ethical code of the Medical Council of India. Administering a lethal injection is an act diametrically opposed to the medical profession's core duty, which is to preserve life, alleviate suffering, and "do no harm." This does not create a separate criminal offence beyond what the IPC provides, but it is important for understanding the complete legal picture.

Under Indian law, no specific provision authorises active euthanasia. Doctors are expressly not permitted under the rules of the Medical Council of India to switch off life support systems or administer lethal substances except in declared brain-dead patients. The deliberate administration of a lethal injection, however compassionate in motive, is therefore both a criminal act and a professional misconduct. The doctor is exposed to action under both the criminal law and the disciplinary jurisdiction of the Medical Council.

The Specific Charges: Section 304 IPC / Section 105 BNS

Since the doctor's act falls under Exception 5 to Section 300 IPC / Section 101 BNS, it is culpable homicide not amounting to murder. The governing punishment provision is Section 304 IPC / Section 105 BNS.

Section 304 is divided into two parts. Part I applies where the culpable homicide was committed with the intention of causing death or with the intention of causing such bodily injury as is likely to cause death. Part II applies where death was caused with the knowledge that the act was likely to cause death but without any intention to cause death or such bodily injury.

In the problem before us, the doctor administered the injection specifically intending the patient to die — that was the very purpose of the act. There is no ambiguity: the injection was lethal by design, administered with the full intention of ending the patient's life. This places the doctor squarely under Part I of Section 304 IPC / Part I of Section 105 BNS, punishable with imprisonment for life, or imprisonment of either description for a term which may extend to ten years, and fine.

The Constitutional Dimension: Aruna Shanbaug and Common Cause

The settled criminal law must, however, be read alongside two landmark constitutional pronouncements that have significantly modified the legal landscape concerning the dying.

In Aruna Ramachandra Shanbaug v. Union of India (AIR 2011 SC 1290), the Supreme Court distinguished between active euthanasia — the deliberate administration of a lethal substance to end life — and passive euthanasia — the withdrawal of life-sustaining treatment, including the discontinuation of a ventilator or artificial nutrition, allowing the person to die naturally. The Court held that passive euthanasia can be permitted in certain exceptional circumstances with the sanction of the High Court. Active euthanasia — the situation in the problem before us — was explicitly held to remain illegal and unpermitted.

This distinction was reaffirmed and deepened by a Constitution Bench of the Supreme Court in Common Cause (A Registered Society) v. Union of India ((2018) 5 SCC 1), where a five-judge bench unanimously recognised the right to die with dignity as an intrinsic part of the right to life under Article 21 of the Constitution. The Court held that a competent adult has the right to execute an Advance Directive — commonly called a Living Will — directing that artificial life support not be administered if the person reaches a vegetative state or terminal illness. The Court laid down detailed safeguards and a procedure for medical boards and High Courts to supervise such decisions.

However — and this must be emphasised with care — even Common Cause did not legalise active euthanasia or physician-assisted suicide. The right recognised is the right to refuse life-prolonging treatment and to die naturally. The right to actively demand that a doctor administer a fatal injection remains outside the law. The distinction between the two — as the Court in Common Cause explicitly stated, echoing the US Supreme Court's analysis in Washington v. Glucksberg (521 US 702, 1997) — is not arbitrary. When a patient refuses a ventilator, the death results from the underlying disease. When a doctor injects a lethal substance, the physician's act causes death. The law draws a firm line between these two situations.

The Final Answer: The Doctor's Criminal Liability

Under the law as it stands today, the doctor in the problem is guilty of culpable homicide not amounting to murder. The patient's free and voluntary consent, being valid under Section 90 IPC / Section 27 BNS, invokes Exception 5 to Section 300 IPC / Exception 5 to Section 101 BNS, which prevents the act from constituting murder. But the exception does not exonerate the doctor. The offence remains culpable homicide under Section 299 IPC / Section 100 BNS, punishable under Part I of Section 304 IPC / Part I of Section 105 BNS with imprisonment for life or up to ten years and fine, since the act was done with the deliberate intention of causing death.

Active euthanasia — the knowing, intentional administration of death at a patient's request — sits in the grey zone between compassion and criminality in Indian law. The criminal law does not ignore the humanity of the act: by reducing the offence from murder to the lower form of culpable homicide, it gives weight to the patient's consent and the doctor's motive. But it does not grant impunity. India has not yet enacted any legislation to legalise physician-assisted suicide, and until it does, the doctor who administers a lethal injection — even at the sincere and urgent request of a dying patient — commits a criminal offence. Whether such a law ought to be enacted, with appropriate safeguards, is perhaps one of the most important questions of legal reform awaiting the Indian Parliament.
