Technology Law Neurotechnology, Law, and the Limits of Intrusion By Adv. Ashish Sonawane Neurotechnology is usually discussed in the language of promise. It is associated with rehabilitation, assistive communication, brain-computer interfaces, and new possibilities for those living with paralysis, epilepsy, depression, and other serious conditions. That promise is real and should not be dismissed. UNESCO has itself recognised both the therapeutic value of neurotechnology and the ethical risks it may pose to dignity, autonomy, freedom of thought, and mental privacy. Its legal significance, however, lies not only in treatment, but in the kind of access it may claim over the human mind. Most technologies engage the body, communication, property, or ordinary personal data. Neurotechnology raises a more difficult legal issue. It concerns technologies that claim the capacity to access, infer, influence, or decode aspects of brain activity and mental states. Once the law enters that terrain, the issue is no longer confined to consumer protection or routine data processing. It begins to concern agency, dignity, and liberty at a deeper level. UNESCO’s neurotechnology framework expressly identifies risks relating to personal identity, autonomy, mental privacy, and freedom of thought. For that reason, neurotechnology cannot be treated merely as another health-tech issue. It lies at the intersection of constitutional liberty, medical ethics, informational privacy, AI governance, product liability, and human rights. If law responds too late, the consequences will not remain technical for long. That is a reasonable inference from the manner in which international institutions are already approaching the field. Its legal significance lies not only in treatment, but in the kind of access it may claim over the human mind. Why neurotechnology is legally different The law is familiar with bodily integrity. It knows how to deal with assault, medical consent, unlawful search, medical negligence, and invasive procedures. Neurotechnology narrows the distance between bodily intervention and mental intrusion. In legal terms, that distinction is critical. A device that records pulse or movement is one thing. A technology that claims to read patterns of cognition, infer intention, classify emotional states, or alter neural response is another. UNESCO has specifically warned that neurotechnology may reveal personal information about identity, emotions, and thoughts, and that AI-linked systems may deepen these risks. To treat this only as a data-governance issue would be too narrow. Neural data may indeed be data in one sense. It may be collected, stored, transferred, or processed. But that does not exhaust the legal problem. The deeper concern is intrusion into a sphere that constitutional democracies have traditionally treated with special care: the protected realm of thought, choice, and self-determination. Indian privacy doctrine, too, has recognised the body and the mind as inseparable elements of human personality. Indian constitutional law is not silent on this concern India does not yet have a direct ruling on neurotechnology governance in its present commercial or clinical form. Even so, the Constitution is not silent on the underlying concerns. In Selvi v. State of Karnataka (2010), while dealing with involuntary narco-analysis, polygraph examination, and the Brain Electrical Activation Profile test, the Supreme Court expressly referred to the subject’s right to privacy “both in a physical and mental sense.” The Court also examined the issue through the lens of personal liberty, self-incrimination, and protection against cruel, inhuman, or degrading treatment. That was not a neurotechnology regulatory case in the modern sense, but its reasoning is directly relevant here. It shows that Indian constitutional law has already recognised that compelled intrusion into mental processes raises concerns different from ordinary physical evidence-gathering. A second important constitutional reference point is K.S. Puttaswamy v. Union of India (2017). The privacy judgment did not concern neurotechnology specifically, but it located privacy within dignity, liberty, and constitutional personhood. Justice Chandrachud’s opinion observed that privacy allows each human being to be left alone in a core “which is inviolable” and that courts must remain sensitive to the opportunities and dangers posed to liberty in a digital world. That reasoning bears directly on this issue. The linkage becomes even sharper in V. Vasanta Mogli v. State of Telangana (2023). Drawing on privacy doctrine, the Telangana High Court observed that the body and the mind are inseparable elements of human personality, that privacy enables autonomy of both body and mind, and that the intersection between mental integrity and privacy entitles the individual to freedom of thought and self-determination. That language is especially useful here because it gives constitutional form to concerns now described internationally as mental privacy, cognitive liberty, and mental integrity. So while Indian courts have not yet framed a standalone doctrine of neurorights, the underlying constitutional principles are already available. Consent remains essential, but it cannot do all the legal work here One weakness of modern technology regulation is the tendency to place excessive weight on formal consent. A signed form, a checkbox, or a privacy notice is often treated as if it resolves the deeper legal problem. In the context of neurotechnology, that would be insufficient. An individual may not fully understand downstream inference risks. The science itself is still evolving. And in many settings, the imbalance of power will be structural rather than incidental. That concern becomes sharper in employment, insurance, education, defence, or custodial contexts, where agreement may exist in form without being fully voluntary in substance. UNESCO’s ethics materials move well beyond mere notice-and-consent language and emphasise misuse prevention, protection of mental privacy, and effective safeguards. A serious legal framework for neurotechnology will therefore require more than disclosure language. It will require purpose limitation, restrictions on coercive deployment, heightened standards for research and clinical use, safeguards against secondary use, meaningful redress, and, in some cases, categorical limits. That is a normative conclusion, but it follows from the nature of the interests involved and from the direction in which current international governance thinking is moving. The greater danger may lie in gradual normalisation The greater danger may lie not in immediate abuse, but in gradual normalisation. It would be unsafe to assume that neurotechnology will remain limited to
