Definition and Essentials

Consent is the voluntary agreement of a person, in possession of and exercising sufficient mental capacity, to permit something to be done that would otherwise be unlawful. In medicine it is the patient's permission for examination, investigation or treatment.

Treatment without consent is an assault or battery, actionable in civil law and potentially criminal, irrespective of whether the treatment was skilful or beneficial. A perfectly performed operation on an unconsenting patient is still a wrong
Essentials of a valid consent — it must be free and voluntary, without fraud, fear, force, coercion or misrepresentation; given by a person of sound mind; given by a person of competent age; informed, after the nature and consequences have been explained; and given for a lawful purpose
Consent to an unlawful act is no consent at all — a person cannot validly consent to female genital mutilation, to a sex-determination test, or to termination outside the MTP Act

Type	Description
Implied consent	Inferred from conduct — a patient who attends the clinic, sits down and offers an arm for examination. It covers routine examination only: inspection, palpation, percussion, auscultation, pulse and blood pressure. It is the commonest form of consent in practice and covers the least
Expressed consent — oral	Stated in words; adequate for most minor procedures, but should be recorded in the notes and, where possible, taken in the presence of a third party
Expressed consent — written	Required for all operative and invasive procedures, general anaesthesia, intimate examination, procedures with material risk, blood transfusion, and any medicolegal examination. The document is evidence of consent, not the consent itself
Informed consent	Consent given after disclosure of the diagnosis, the nature and purpose of the proposed treatment, the risks and benefits, the alternatives with their risks, and the consequences OF refusing. This is the standard now expected, and Indian courts have moved toward what a reasonable patient would wish to know rather than what a reasonable doctor would disclose
Blanket consent	A general form signed on admission covering "any treatment". It is of little legal value for any specific procedure and does not substitute for procedure-specific consent
Proxy (substituted) consent	Given by a parent, guardian or person in LOCO parentis for one who cannot consent, in that person's best interests
Loco parentis	A teacher, warden or other adult in temporary charge may consent for a child in an emergency where the parents cannot be reached

CLINICAL PEARL

The signed form is evidence of consent, not consent itself. A signature obtained on the trolley outside theatre, from a premedicated patient, on a form nobody read aloud, proves that a piece of paper exists — and courts have said so repeatedly. What matters is the conversation: what was explained, in what language, to whom, and what was asked. A brief note of that conversation in the case sheet is worth more than the form, and its absence is what actually loses cases.

Age and the Statutory Provisions

Provision (BNS 2023 / formerly IPC)	Effect
BNS 25 (IPC 90)	Defines what is not consent — consent given under fear of injury or under a misconception of fact; by a person of unsound mind or intoxicated so as not to understand; or by a person under 12 years
BNS 26 (IPC 87)	An act not intended and not known to be likely to cause death or grievous hurt, done with the consent of a person above 18, is not an offence
BNS 27 (IPC 88)	An act done in good faith for the person's benefit, with consent, is not an offence even if it causes harm — the provision that protects surgery. The surgeon who amputates to save life is covered by this
BNS 28 (IPC 89)	An act done in good faith for the benefit of a child under 12 or a person of unsound mind, with the consent of the guardian, is not an offence
BNS 30 (IPC 92)	An act done in good faith for a person's benefit without consent, where circumstances make it impossible to obtain consent and there is no time — the emergency provision. It is the doctor's protection in the unconscious patient

The practical age rules — 12 years for consent to examination; 18 years for consent to any procedure carrying risk to life, to general anaesthesia and to surgery; and 18 years for a valid consent to an act that may cause harm
Below the relevant age, the guardian consents — but the assent of an older child should also be sought, and a competent adolescent's objection cannot simply be disregarded
Special statutory ages — 18 years for consent to sexual intercourse (below which it is rape irrespective of consent, and an offence under POCSO); 18 years for the woman's own consent to termination of pregnancy under the MTP Act (a guardian consents below that); and 18 years for organ donation

Consent in Special Situations

Situation	Rule
Emergency in an unconscious patient	Treat under BNS 30 (IPC 92); consent is not required for life-saving treatment. Document the emergency and the reason consent could not be obtained
Married woman — sterilisation, MTP	The woman'S own consent is sufficient and necessary. The husband'S consent is not required for MTP or sterilisation, and performing a procedure on the husband's consent against the woman's wishes is unlawful
Examination of an accused person	Under BNSS 51 (CrPC 53), a registered practitioner may examine an accused at the request of a police officer of at least sub-inspector rank, using reasonable force if necessary; consent is not required. A female accused is examined only by or under the supervision of a female doctor
Examination of a victim of sexual assault	Consent IS essential (BNSS 184; CrPC 164A). Treatment must be given free of cost, and refusal to treat is an offence
Prisoner	A prisoner retains the right to consent and to refuse; imprisonment does not remove autonomy
Person of unsound mind	Guardian consents. Under the Mental Healthcare Act 2017 a person may make an advance directive and appoint a nominated representative
Blood transfusion refused on religious grounds	A competent adult'S refusal must be respected even where death will follow; for a child, the court may be approached and the child's interests prevail
Clinical research	Written informed consent, ethics committee approval, and the right to withdraw at any time without prejudice to care
Organ donation	Written consent of the donor before two witnesses, and of the next of kin in a deceased donor; authorisation committee approval for unrelated donors

What Must Be Disclosed for Consent to Be Informed

The diagnosis and the nature of the condition, in language the patient understands and in their own language where necessary
The nature and purpose of the proposed treatment, described in terms of what will actually be done to them
The risks — both the common minor ones and the rare but serious ones. A very small risk of death or paralysis must be disclosed although a small risk of nausea need not, because materiality depends on gravity as well as frequency
The expected benefit, stated honestly and without overstatement
The alternatives, including conservative management and doing nothing, each with its own risks — a patient offered only one option has not been given a choice
The consequences OF refusing
The cost, and who will perform the procedure
The standard of disclosure in India has moved from what a reasonable doctor would disclose toward what a reasonable patient would wish to know — and Samira Kohli established that consent is procedure-specific, so that consent for diagnosis does not authorise treatment discovered to be necessary
An opportunity to ask questions, and a record that it was given

Applied Aspects

Take consent yourself, or ensure the person who takes it can answer the questions; consent obtained by an intern who cannot describe the operation is not informed consent and will not survive examination
Record the conversation, not just the signature — a line in the notes stating what was explained, in which language, to whom, and what was asked, is the single most valuable entry in a consent dispute
Take consent before premedication, and not on the trolley; consent from a sedated patient is worthless and the timing is easily proved from the drug chart
Consent is procedure-specific; a consent for diagnostic laparoscopy does not authorise a hysterectomy, and extending an operation beyond what was consented to is defensible only where it was an emergency that could not have been anticipated
Do not accept the husband's consent for the wife; this remains common practice in India and is legally wrong, and it exposes the doctor completely if the woman later objects
Document a refusal as carefully as a consent — what was explained, the risks of refusing, that the patient understood, and their signature or that of a witness; a discharge against medical advice with no such record is indefensible
Blanket admission consent authorises nothing specific; every operative or invasive procedure needs its own consent naming that procedure
An accused may be examined without consent under BNSS 51, with reasonable force if necessary — but a victim of sexual assault may not, and the difference between the two is absolute
A female accused is examined only by or under the supervision of a female doctor; this is statutory and not a matter of preference
Seek the assent of an older child even where the guardian consents; a competent adolescent’s objection cannot simply be overridden without thought
Emergency treatment of the unconscious is protected by BNS 30, but the emergency and the impossibility of obtaining consent must be recorded at the time
Consent to an unlawful act is void; no consent makes a sex-determination test or an unlawful termination legal, and the doctor is liable regardless
