1. Legal Concept: What “Neural Consent” Really Means

In legal reasoning, neural consent is not “brain reading consent.” It is:

A reconstructed or substituted consent derived from earlier autonomous decisions of a person whose present neurological condition prevents fresh consent.

Courts use three interpretive tools:

• Prior expressed intent (advance consent)
• Implied consent from conduct (e.g., initiating IVF process)
• Best-interest + reproductive autonomy balancing

It is especially relevant under assisted reproduction law (IVF, gamete retrieval, embryo freezing).

2. Constitutional Foundation (India & Comparative Law)

Courts link neural consent to:

• Article 21 – Right to life and personal liberty
• Includes:
  • reproductive autonomy
  • dignity
  • decisional privacy

The Delhi High Court recently emphasized that reproductive autonomy survives incapacitation if prior intent exists .

3. Key Principle: Consent Does Not Always Require Real-Time Capacity

Modern jurisprudence increasingly recognizes:

• Consent can be durable (continuing) if previously established
• Medical incapacity does not automatically extinguish reproductive intent
• Spouse may act as procedural proxy, not substitute owner of autonomy

4. Leading Case Laws on Neural Consent in Reproductive Disputes

(A) India — Assisted Reproductive Technology & Incapacity Cases

1. Delhi High Court (2026) – Soldier in Vegetative State IVF Case

• Court allowed sperm extraction despite lack of fresh written consent.
• Held:
  • prior IVF intention = valid consent
  • reproductive autonomy continues despite incapacity
• Recognized that denying procedure would defeat original consent 

2. Delhi High Court (2026) – ART Act Interpretation Case

• Held written consent is not indispensable under ART Act, 2021.
• Allowed cryopreservation based on earlier conduct and intention 

Legal significance:

• Introduces concept of functional consent over formal consent
• Strengthens neural consent doctrine

3. Kerala High Court (2026) – Brain-dead Husband Gamete Retrieval Case

• Allowed wife to retrieve gametes of brain-dead spouse.
• Conditions:
  • no further ART without court permission
• Recognized urgency and irreversibility of reproductive timeline 

Key idea:

• Courts may permit biological preservation as a protective measure of potential reproductive autonomy

4. Puttaswamy v. Union of India (2017, Supreme Court)

• Privacy declared a fundamental right.
• Includes:
  • bodily integrity
  • decisional autonomy

Relevance to neural consent:

• Forms constitutional base for reproductive autonomy even when decision-making capacity changes.

5. Common Cause v. Union of India (2018, Supreme Court)

• Recognized passive euthanasia and living wills
• Introduced concept of:
  • advance directives

Relevance:

• Strong analogy for neural consent:
  • past consent governs future incapacity

(B) International Case Law

6. Kass v. Kass (USA, 1998)

• IVF consent forms held binding.
• Court prioritized:
  • written prior consent agreements
  • intent at time of embryo creation

Importance:

• Establishes principle that reproductive consent is contract-like and durable

7. In re Marriage of Witten (Iowa, USA, 2003)

• Dispute over frozen embryos after divorce.
• Court ruled:
  • prior agreement governs disposition
  • autonomy must be respected over later objections

Relevance:

• Reinforces that consent once given may persist despite changed circumstances

5. Legal Theories Behind Neural Consent

(A) Continuing Consent Theory

• Consent persists until explicitly revoked.
• Incapacity does not automatically revoke it.

(B) Substituted Judgment Doctrine

• Decision made as if the person were competent.
• Used in medical ethics and guardianship law.

(C) Best Interest + Autonomy Hybrid

• Courts balance:
  • dignity of the incapacitated person
  • reproductive rights of spouse
  • medical feasibility

6. Emerging Neuro-Legal Dimension

With neurotechnology and brain-computer interfaces, scholars warn:

• future systems may detect:
  • intention signals
  • cognitive preferences
• but legal systems currently do NOT treat brain signals as consent unless explicitly validated

So neural consent remains:

a legal fiction based on prior autonomy, not neural decoding

7. Key Legal Issues in Neural Consent Disputes

1. Authenticity Problem

• Was prior consent truly informed?

2. Revocation Problem

• Can silence or incapacity revoke earlier consent?

3. Proxy Authority Problem

• Does spouse represent patient or act independently?

4. Reproductive Finality Problem

• IVF and gamete retrieval are irreversible biological acts

8. Summary

Neural consent in reproductive disputes is best understood as:

a doctrine that preserves reproductive autonomy through prior consent when neurological incapacity prevents fresh decision-making.

It is not based on reading the brain, but on:

• prior intent
• constitutional autonomy
• statutory interpretation of ART laws
• ethical continuity of personhood
