Liability For Consent Exhaustion.
1. Introduction
Consent exhaustion refers to a situation in which an individual's ability or willingness to give meaningful, voluntary, informed and continuing consent becomes weakened or depleted because of repeated requests for consent, prolonged exposure to consent procedures, excessive medical interventions, repeated data-sharing demands, psychological pressure, or continuous participation in experimental activities.
The concept is particularly relevant to:
Medical treatment and surgical procedures.
Biotechnology and genetic engineering.
Clinical trials and biomedical research.
Artificial intelligence and personal-data processing.
Organ transplantation and tissue donation.
Reproductive technologies.
Psychological experimentation.
Long-term medical monitoring and biological interventions.
Consent exhaustion is not yet a universally recognised, independent legal cause of action. It is better understood as a developing legal and ethical problem that can be addressed through established principles of informed consent, medical negligence, battery, privacy, bodily autonomy, coercion and consumer protection.
The central legal question is:
Can an institution, medical professional, researcher or biotechnology company be held liable when it continues obtaining or relying upon consent even though the individual's capacity to make a genuinely voluntary and informed decision has been undermined by repeated consent demands or prolonged intervention?
The answer may be yes, depending on the circumstances and the applicable legal framework.
2. Meaning and nature of consent exhaustion
Consent exhaustion occurs when repeated or continuous consent-seeking practices undermine the effectiveness of an individual's decision-making process.
For example:
A hospital repeatedly asks a critically ill patient to approve additional experimental procedures.
A biotechnology company obtains consent for successive genetic modifications without adequately explaining their cumulative consequences.
A clinical research institution repeatedly requests consent for additional experiments from participants who are psychologically dependent on the institution.
A digital healthcare platform continuously seeks permission for increasingly intrusive uses of genetic and medical information.
A researcher obtains multiple signatures from a participant without ensuring that the participant understands the implications of each new intervention.
In these circumstances, the existence of a signed consent form does not necessarily establish legally valid consent.
Essential characteristics
| Characteristic | Legal significance |
|---|---|
| Repeated consent requests | May create psychological pressure |
| Information overload | May undermine informed decision-making |
| Consent fatigue | May weaken meaningful participation |
| Dependency | May compromise voluntariness |
| Cumulative interventions | May exceed the original consent |
| Failure to renew consent | May invalidate authorisation for new procedures |
| Inability to withdraw | May violate autonomy |
3. Legal foundations of liability for consent exhaustion in India
Indian law does not expressly define consent exhaustion as a separate legal wrong. Nevertheless, several constitutional, statutory and judicial principles provide a basis for addressing it.
A. Article 21 – Right to life, dignity and bodily autonomy
Article 21 of the Constitution of India protects life and personal liberty.
The right includes important protections relating to:
Bodily integrity.
Personal autonomy.
Human dignity.
Medical decision-making.
Privacy.
Reproductive freedom.
The right to refuse medical treatment.
Consent exhaustion may violate Article 21 where repeated institutional pressure effectively deprives an individual of meaningful control over their body.
For instance, a hospital cannot justify repeated experimental procedures merely by producing a series of signed consent forms if the patient's autonomy has been compromised.
B. Article 14 – Protection against arbitrary conduct
Article 14 guarantees equality before the law and equal protection of laws.
Government hospitals, public research institutions and other State authorities must act fairly and reasonably.
Consent exhaustion may raise Article 14 concerns where:
Vulnerable patients are repeatedly pressured into medical procedures.
Consent requirements are applied arbitrarily.
Institutions exploit unequal bargaining power.
Patients are denied reasonable opportunities to refuse.
Research participants are treated differently without justification.
C. Indian Contract Act, 1872
The Contract Act provides important principles for determining whether consent is legally valid.
Relevant provisions include:
Section 13: Defines consent as agreeing upon the same thing in the same sense.
Section 14: Defines free consent.
Section 15: Defines coercion.
Section 16: Defines undue influence.
Section 17: Defines fraud.
Section 18: Defines misrepresentation.
Section 19: Deals with agreements voidable where consent is caused by coercion, fraud or misrepresentation.
Section 19A: Deals with agreements induced by undue influence.
These provisions become relevant when repeated consent requests involve intimidation, manipulation, deception or exploitation of a person's dependent condition.
Example: A research organisation repeatedly asks an economically vulnerable participant to approve additional genetic experiments, suggesting that medical assistance will be withdrawn unless the participant agrees.
Depending on the facts, such conduct may amount to undue influence or coercion.
However, mere repetition of a consent request does not automatically establish coercion or undue influence.
D. Consumer Protection Act, 2019
A hospital or healthcare provider may face liability for deficiency in service where the applicable requirements of consumer law are satisfied.
Possible grounds include:
Obtaining defective consent.
Performing unauthorised procedures.
Concealing material information.
Failing to explain additional risks.
Continuing treatment beyond authorised limits.
Failing to respect a patient's refusal.
Compensation may be claimed for established injury, suffering and other legally recoverable losses.
E. Digital Personal Data Protection Act, 2023
Consent exhaustion is also relevant to digital healthcare and biotechnology platforms.
For example, a genetic-testing company may repeatedly request permission to process additional categories of personal data.
The Digital Personal Data Protection Act, 2023, provides a framework concerning consent, specified purposes, withdrawal and obligations of data fiduciaries, subject to its applicable provisions and commencement.
Repeated requests do not themselves establish a statutory violation. However, consent must satisfy the applicable legal requirements; a pattern of confusing, manipulative or misleading requests may be legally significant.
4. Important Indian case laws
The following decisions provide the strongest judicial foundations for analysing consent exhaustion.
Case 1. Samira Kohli v. Dr. Prabha Manchanda (2008) 2 SCC 1
Leading Indian authority
Court: Supreme Court of India.
Facts:
Samira Kohli visited a medical practitioner for diagnostic laparoscopy. She consented to the diagnostic procedure.
While she was under general anaesthesia, the doctors obtained consent from her mother and proceeded to perform a hysterectomy and remove her ovaries and fallopian tubes.
The patient had not personally authorised this additional surgery.
Legal issue:
Whether consent for a diagnostic procedure could authorise a substantially different therapeutic operation.
Judgment:
The Supreme Court held that the patient's consent must be real and valid.
The Court explained that valid consent requires:
Capacity and competence.
Voluntariness.
Adequate information concerning the nature of the procedure.
Consent for diagnostic treatment cannot automatically be treated as consent for therapeutic treatment.
An additional procedure may be undertaken without fresh consent only in restricted circumstances, particularly where it is necessary to save life or preserve health and postponement would be unreasonable.
Relevance to consent exhaustion:
This decision establishes that consent is procedure-specific. Repeated or general consent cannot be used as unlimited authorisation for future interventions.
A biotechnology company, hospital or research organisation cannot rely upon an earlier broad consent to justify substantially different procedures without satisfying the relevant consent requirements.
Legal principle: Consent is not a permanent or unlimited authorisation to interfere with an individual's body.
Case 2. Justice K.S. Puttaswamy (Retd.) v. Union of India (2017) 10 SCC 1
Court: Supreme Court of India, nine-judge Constitution Bench.
Facts:
The case concerned the constitutional status of the right to privacy and the relationship between privacy, liberty and individual dignity.
Legal issue:
Whether privacy is protected as a fundamental right under the Indian Constitution.
Judgment:
The Supreme Court unanimously recognised privacy as a fundamental right protected under Article 21 and other constitutional freedoms.
The judgment recognised privacy as closely connected with:
Personal autonomy.
Individual dignity.
Control over personal information.
Decisions concerning one's body.
Personal choices and freedom.
Relevance to consent exhaustion:
Repeated demands for personal, genetic or medical information can undermine meaningful individual control over private information.
For example, a genetic-testing platform that continuously seeks additional permissions without meaningful explanations may raise serious privacy and autonomy concerns.
Legal principle: Personal autonomy and privacy require meaningful individual control over decisions affecting one's private life.
Case 3. Common Cause v. Union of India (2018) 5 SCC 1
Court: Supreme Court of India, Constitution Bench.
Facts:
The proceedings concerned the legality of passive euthanasia and advance medical directives.
Legal issue:
Whether an individual has the right to refuse life-sustaining medical treatment and make decisions concerning end-of-life care.
Judgment:
The Supreme Court recognised the right to die with dignity as part of Article 21 and upheld the legal validity of advance medical directives subject to prescribed safeguards.
The judgment recognised the importance of individual autonomy in medical decision-making.
Relevance to consent exhaustion:
The decision supports the proposition that medical treatment cannot be understood merely as a matter of institutional authority.
A patient's decision to refuse further treatment deserves legal respect, subject to applicable law.
A medical institution cannot treat repeated requests for consent as permission to disregard an individual's refusal.
Legal principle: Medical autonomy includes legally protected decisions concerning the continuation or refusal of treatment.
Case 4. Aruna Ramachandra Shanbaug v. Union of India (2011) 4 SCC 454
Court: Supreme Court of India.
Facts:
The case concerned a woman who had remained in a persistent vegetative state for decades following a brutal assault.
The Court examined the legal and ethical questions surrounding withdrawal of life-sustaining treatment.
Legal issue:
Whether passive euthanasia could be legally permitted under Indian law.
Judgment:
The Court recognised the possibility of passive euthanasia under specified judicial safeguards at that time.
The legal framework was subsequently reconsidered and developed by the Constitution Bench in Common Cause.
Relevance to consent exhaustion:
The judgment demonstrates the importance of careful safeguards in medical decisions involving patients who cannot independently communicate their wishes.
Where patients lack decision-making capacity, institutions must not treat repeated procedural approvals as a substitute for legally appropriate decision-making.
Case 5. Indian Medical Association v. V.P. Shantha (1995) 6 SCC 651
Court: Supreme Court of India.
Facts:
The case concerned whether medical services fall within the scope of consumer protection legislation.
Legal issue:
Whether patients could invoke consumer protection remedies against medical practitioners and hospitals.
Judgment:
The Supreme Court recognised that medical services generally fall within the scope of consumer protection law, subject to the qualifications explained in the judgment.
Relevance to consent exhaustion:
Where repeated consent procedures are conducted negligently or without proper disclosure and result in harm, the affected patient may have a consumer-law remedy if the relevant statutory requirements are met.
The case provides an important foundation for pursuing claims arising from defective medical services.
5. Important international case laws
International decisions are persuasive comparative authorities, although their binding force depends on the jurisdiction.
Case 6. Montgomery v. Lanarkshire Health Board [2015] UKSC 11
Court: UK Supreme Court.
Facts:
A pregnant woman with diabetes was not adequately informed about the risk of shoulder dystocia during vaginal delivery or the alternative of a caesarean section.
Legal issue:
What information must a medical practitioner disclose before obtaining consent?
Judgment:
The Court held that medical practitioners must take reasonable care to ensure that patients are aware of material risks and reasonable alternative treatments.
A risk is material where a reasonable person in the patient's position would likely attach significance to it, or the doctor knows or ought reasonably to know that the particular patient would do so.
Relevance to consent exhaustion:
A consent process should provide meaningful information rather than simply obtain repeated signatures.
Where information overload or repeated requests prevent meaningful understanding of material risks, the adequacy of the consent process may be questioned.
Case 7. Canterbury v. Spence (1972) 464 F.2d 772
Court: United States Court of Appeals, District of Columbia Circuit.
Facts:
The patient underwent spinal surgery without adequate disclosure of relevant risks.
Legal issue:
Whether a physician has a duty to disclose material risks before treatment.
Judgment:
The Court recognised the importance of disclosure and the patient's right to make an informed medical decision.
It emphasised that consent must be free from imposition and supported by adequate explanation.
Relevance to consent exhaustion:
The decision supports the argument that a consent form cannot replace meaningful communication.
Repeated formal consent requests are inadequate if the patient is confused, intimidated or unable to make an informed decision.
Case 8. Schloendorff v. Society of New York Hospital (1914) 211 N.Y. 125
Court: New York Court of Appeals.
Facts:
A patient consented to an examination under anaesthesia but did not consent to the removal of a tumour. The doctors nevertheless performed the operation.
Legal issue:
Whether a doctor may perform an operation without the patient's consent.
Judgment:
Justice Benjamin Cardozo famously recognised the principle that an adult of sound mind has the right to determine what shall be done with their body.
Relevance to consent exhaustion:
Consent must be treated as a genuine expression of individual choice. Previous cooperation or agreement to an earlier procedure does not constitute unlimited permission for subsequent interventions.
Case 9. Rogers v. Whitaker (1992) 175 CLR 479
Court: High Court of Australia.
Facts:
A patient underwent eye surgery without adequate disclosure of a serious risk affecting her remaining vision.
Legal issue:
Whether the medical practitioner had adequately disclosed material risks.
Judgment:
The Court emphasised the duty to disclose material risks, including risks that a particular patient would consider significant.
Relevance to consent exhaustion:
The case reinforces the need for patient-centred communication. Repeated consent procedures must not become mechanical exercises that ignore the patient's individual concerns and circumstances.
6. Legal elements necessary to establish liability for consent exhaustion
Consent exhaustion alone does not automatically create liability. A claimant generally needs to establish an existing legal wrong, such as negligence, coercion, unauthorised treatment, breach of privacy or violation of a statutory duty.
The following elements are particularly important.
1. Existence of repeated or excessive consent demands
The claimant must establish that the defendant repeatedly sought consent or relied on consent in circumstances that potentially undermined voluntary decision-making.
Examples:
Repeated requests for experimental surgery.
Continuous requests for genetic modification.
Repeated demands for access to biological information.
Multiple consent forms for substantially related procedures.
2. Diminished voluntariness
The claimant must demonstrate that consent was obtained through circumstances affecting genuine freedom of choice.
Possible circumstances include:
Psychological pressure.
Institutional dependency.
Threats of withdrawal of medical assistance.
Exploitation of physical weakness.
Manipulation through fear.
Undue influence.
3. Failure to provide meaningful information
The defendant may be liable if material information was not adequately communicated.
This includes failure to explain:
The nature of the intervention.
Its purpose.
Material risks.
Alternative procedures.
Cumulative consequences.
The right to refuse.
The possibility of withdrawing consent.
4. Absence of meaningful renewal of consent
Where an intervention changes substantially, fresh consent may be required.
For example, consent for a genetic diagnostic test does not automatically authorise permanent genetic modification.
Similarly, consent for one medical procedure does not necessarily authorise subsequent experimental procedures.
5. Causation
The claimant must establish the necessary connection between the defendant's wrongful conduct and the injury.
Possible injuries include:
Physical injury.
Psychological trauma.
Unauthorised medical intervention.
Loss of reproductive capacity.
Genetic damage.
Financial loss.
Unlawful disclosure or misuse of personal data.
6. Legally recognised damage or violation
The nature of the remedy depends on the cause of action.
For example, unauthorised bodily interference may constitute a tort even where the procedure was medically beneficial. A negligence claim ordinarily requires proof of the applicable duty, breach, causation and damage.
7. Liability in different sectors
Consent exhaustion has different legal implications depending on the activity involved.
A. Medical treatment
A medical practitioner may face liability where the practitioner repeatedly seeks consent without properly explaining the treatment or exploits a patient's vulnerable condition.
Example:
A patient undergoing cancer treatment is repeatedly asked to approve additional experimental procedures. The hospital does not adequately explain the risks and makes the patient believe that refusing the experiment will terminate ordinary treatment.
Potential liability:
Medical negligence.
Deficiency in medical service.
Undue influence or coercion, where established.
Unauthorised bodily interference.
Constitutional remedies where State action is involved.
B. Biotechnology and genetic engineering
Post-2026 Gene Editing: New Clinical Trials Revolutionize Chronic Care | EzeeMedia
Biotechnology presents particularly serious consent-related challenges because genetic interventions may have long-term or irreversible consequences.
Example:
A biotechnology company obtains initial consent for genetic testing and subsequently uses the participant's biological material for gene modification, without obtaining the necessary additional authorisation.
Potential liability:
Breach of consent conditions.
Negligence.
Privacy violations.
Contractual liability.
Statutory regulatory violations.
The original consent should not be treated as unrestricted permission for every subsequent biological intervention.
C. Clinical trials and biomedical research
Transforming Lives: The Ripple Effect of Medical Research...
Clinical research participants may experience consent fatigue when repeatedly asked to approve additional investigations.
Important legal and ethical safeguards include:
Independent ethics committee review.
Clear participant information sheets.
Voluntary participation.
Adequate explanation of risks.
Freedom to withdraw, subject to applicable legal requirements.
Appropriate safeguards for vulnerable participants.
Proper documentation of consent.
In India, the New Drugs and Clinical Trials Rules, 2019, and applicable biomedical research ethics requirements are relevant.
The Indian Council of Medical Research's National Ethical Guidelines for Biomedical and Health Research Involving Human Participants, 2017, also provide important guidance.
D. Artificial intelligence and digital healthcare
AI Governance in Healthcare on Databricks: Guardrails, Compliance, and Data Security
Digital platforms may repeatedly seek consent for:
Medical data collection.
Genetic information processing.
Biometric monitoring.
AI-based diagnosis.
Predictive health assessments.
Sharing information with third parties.
A person may mechanically click an approval button without understanding the consequences.
The legal issue is whether the consent meets the applicable requirements of data protection law, rather than simply whether a consent button was clicked.
E. Organ transplantation and tissue donation
Repeated requests to donate organs or tissues may become problematic where individuals are psychologically pressured or dependent upon the recipient or institution.
Indian transplantation law requires compliance with the Transplantation of Human Organs and Tissues Act, 1994, and its applicable rules.
Consent must be assessed in accordance with the specific statutory requirements governing the donation.
8. Important statutory and regulatory provisions
The following legal provisions may be relevant to consent exhaustion claims in India.
| Law | Relevant provision | Importance |
|---|---|---|
| Constitution of India | Article 14 | Protection against arbitrary State action |
| Constitution of India | Article 21 | Dignity, liberty and autonomy |
| Indian Contract Act, 1872 | Sections 13–19A | Consent, coercion and undue influence |
| Consumer Protection Act, 2019 | Sections 2(11), 35 and 39 | Deficiency, complaints and remedies |
| Bharatiya Nyaya Sanhita, 2023 | Section 87 | Certain acts involving a woman without consent, subject to its ingredients |
| Bharatiya Nyaya Sanhita, 2023 | Section 115 | Voluntarily causing hurt |
| Digital Personal Data Protection Act, 2023 | Sections 5–7 | Notice, consent and certain legitimate uses, subject to commencement |
| Transplantation of Human Organs and Tissues Act, 1994 | Applicable consent provisions | Regulation of organ and tissue donation |
Important qualification: Criminal liability does not arise merely because consent was repeatedly requested. The prosecution must establish the specific ingredients of the relevant criminal offence.
9. Defences available to defendants
A doctor, hospital, research institution or biotechnology company may raise several defences.
1. Valid informed consent
The defendant may establish that the individual possessed capacity, received adequate information and voluntarily authorised the procedure.
2. Absence of coercion
Repeated requests do not necessarily amount to coercion. The defendant may demonstrate that the participant remained free to refuse.
3. Medical necessity
An additional emergency procedure may be justified where the legal requirements of necessity are satisfied.
4. Independent decision-making
Evidence that the individual received independent advice and adequate time to consider the decision may support the validity of consent.
5. No causal connection
The defendant may argue that the alleged consent-related failure did not cause the claimed injury.
6. Statutory authority
A procedure may be justified where expressly authorised by applicable legislation, subject to constitutional safeguards and statutory conditions.
However, a signed consent form alone is not an absolute defence.
10. Remedies available to victims
A person affected by consent exhaustion may seek different remedies depending on the circumstances.
| Remedy | Purpose |
|---|---|
| Compensatory damages | Compensation for established injury and loss |
| Consumer complaint | Remedy for deficiency in medical services |
| Constitutional writ | Protection against unlawful State action |
| Injunction | Prevention of further unauthorised intervention |
| Declaration | Judicial determination of rights |
| Criminal proceedings | Where the ingredients of a criminal offence exist |
| Data protection remedies | Where applicable statutory data rights are violated |
| Regulatory complaint | Investigation of medical or research misconduct |
For medical negligence, compensation may include legally recoverable medical expenses, loss of income, physical suffering and psychological injury.
In cases of unauthorised procedures, the nature and extent of bodily interference may also be relevant to damages.
11. Hypothetical judicial analysis
Consider the following hypothetical situation.
A biotechnology research centre recruits an individual for a genetic diagnostic experiment. Initially, the participant provides informed consent.
Over the following months:
The centre requests consent for additional genetic testing.
It introduces new experimental procedures.
It repeatedly seeks permission to share biological information.
It does not adequately explain cumulative risks.
The participant becomes psychologically dependent on the research centre.
The participant eventually agrees to an irreversible genetic intervention.
The intervention subsequently causes serious physical complications.
How would a court approach the dispute?
| Judicial question | Relevant legal principle |
|---|---|
| Was the original consent valid? | Samira Kohli |
| Did consent extend to additional procedures? | Samira Kohli |
| Were material risks disclosed? | Montgomery |
| Was consent voluntary? | Contract Act, Sections 14–16 |
| Was genetic information adequately protected? | Puttaswamy and applicable data protection law |
| Was the intervention negligent? | Medical negligence principles |
| Did the intervention cause injury? | Causation and damages principles |
A court would examine the consent documents, communications, research protocols, medical records, participant capacity, evidence of psychological pressure and the circumstances surrounding the intervention.
If the institution knowingly exploited the participant's vulnerability and proceeded without valid authorisation, it could face civil, regulatory or, where the statutory ingredients are established, criminal liability.
12. Difference between consent fatigue, consent exhaustion and withdrawal of consent
These concepts are related but not identical.
| Concept | Meaning |
|---|---|
| Consent fatigue | Reduced attention or willingness resulting from repeated consent requests |
| Consent exhaustion | A broader condition in which repeated consent procedures undermine meaningful voluntary decision-making |
| Withdrawal of consent | An individual's decision to revoke previously granted permission |
| Invalid consent | Consent that fails applicable legal requirements |
| Coerced consent | Consent obtained through legally recognised coercion |
| Undue influence | Improper use of a position of dominance to obtain consent |
Consent fatigue may be evidence of consent exhaustion, but it does not automatically establish invalid consent.
Likewise, withdrawal of consent is a distinct legal act and must be dealt with according to the relevant medical, contractual, research or data protection framework.
13. Emerging legal challenges
Consent exhaustion is particularly important in future legal disputes involving advanced biotechnology.
Some emerging questions include:
1. Genetic consent exhaustion: Can repeated permissions authorise increasingly intrusive genetic modifications?
2. Biological data exhaustion: Can repeated requests for access to biological information undermine meaningful privacy choices?
3. AI consent exhaustion: Can automated platforms rely upon repeated approval clicks as evidence of meaningful consent?
4. Experimental consent exhaustion: Can researchers continue obtaining approvals from participants who have become psychologically dependent on the research institution?
5. Reproductive consent exhaustion: Can repeated requests for reproductive procedures amount to improper interference with reproductive autonomy?
6. Neural consent exhaustion: Can consent remain legally meaningful where repeated neurological interventions potentially affect decision-making abilities?
7. Collective consent exhaustion: How should the law address repeated consent demands affecting communities whose shared biological resources are being studied or modified?
These are developing legal questions. Their resolution will depend on established legal doctrines, scientific evidence and future judicial interpretation.
14. Critical analysis
The principal difficulty is that traditional consent doctrine generally evaluates consent at a particular moment, whereas consent exhaustion concerns the cumulative effect of repeated interactions.
A person may initially possess full decision-making capacity and voluntarily agree to a procedure. However, after repeated demands, psychological pressure, information overload and dependency, the circumstances surrounding later decisions may become materially different.
This creates three important legal problems.
First, the signature problem: Institutions may rely on signed documents without examining whether the individual genuinely understood the intervention.
Second, the cumulative pressure problem: Courts must consider whether repeated requests, viewed together, created an environment in which refusal became practically difficult.
Third, the continuing autonomy problem: Consent should not be treated as an unlimited authorisation for future procedures, particularly where interventions are substantially different or irreversible.
The law should therefore distinguish between the formal existence of consent and the substantive validity of consent.
15. Conclusion
Liability for consent exhaustion represents an emerging issue at the intersection of constitutional law, medical negligence, contract law, biotechnology regulation, consumer protection and privacy law.
Although Indian courts have not yet established consent exhaustion as an independent cause of action, existing jurisprudence provides substantial protection against defective, coerced and unauthorised consent.
The most important Indian authority is Samira Kohli v. Dr. Prabha Manchanda (2008), which establishes that consent must be real, voluntary and sufficiently informed, and cannot automatically extend to substantially different procedures.
The constitutional principles in K.S. Puttaswamy and Common Cause further reinforce the importance of privacy, dignity and medical autonomy.
The ultimate legal principle is that repeated consent cannot replace meaningful consent. A medical practitioner, researcher or biotechnology institution must respect the individual's continuing autonomy and cannot use consent fatigue, dependency or procedural repetition to justify an intervention that has not been validly authorised.

Academic qualification: Consent exhaustion is an analytical concept rather than an independently settled Indian legal doctrine. The cases above establish the underlying principles, not a judicially recognised standalone tort of consent exhaustion.
I can also prepare a detailed research-paper style analysis of consent exhaustion, including constitutional arguments, biotechnology liability, judicial reasoning and proposed legal reforms in India.
