Facial Recognition Surveillance at Protests Faces in and
Two concurrent constitutional challenges—one filed before the by student activist Aishe Ghosh, the other before the of India under by Rajya Sabha MP A.A. Rahim—have thrust a singular question into the centre of Indian public law: on what legal authority does the State deploy facial recognition technology (FRT) to biometrically map and retain the identities of citizens exercising their right to peacefully assemble? The answer, as both petitions contend, is none . The technology itself is not the problem; the absence of any governing statute is. That vacuum, rather than the cameras or algorithms, is what renders this moment constitutionally significant.
A Vacuum Dressed as Policy
The events that triggered these challenges unfolded last month at Jantar Mantar, where students gathered to demand accountability for the NEET paper-leak scandal. A mobile command vehicle rolled in behind the crowd, its telescopic mast fitted with cameras sweeping a 360-degree arc over the assembly. Photographs circulated of AI-enabled smart spectacles worn by personnel, of handheld scanners pointed at faces, and of a facial recognition unit reportedly named "Ikshana." All of this fed into a wider network of AI-linked CCTV cameras that the had inaugurated with considerable fanfare earlier this year, integrating with a centralised command centre.
Yet when the legal basis is examined, the architecture collapses. The —often cited by police to justify biometric collection—is confined by its text to persons arrested, convicted, or otherwise brought within the criminal process. It says nothing about capturing the faces of citizens simply because they attended a protest. The , meanwhile, carves out broad exemptions for State processing in the interests of sovereignty and public order, and remains substantially unenforced in the absence of an operational . Neither statute was drafted with a scenario like Jantar Mantar in mind, and neither constrains it.
What exists is : a network deployed at scale, answerable to no statute, and therefore—in constitutional terms—answerable to no one. Right to Information applications pursued through the have struggled to establish even basic facts: what data is collected, how long it is retained, against which databases it is matched, and who authorised its deployment at a protest rather than at a crime scene. This is not incidental opacity; it is what a looks like in practice.
The , Applied to a Crowd
The constitutional vocabulary to test this practice already exists. In , the established that any State action infringing privacy must clear three hurdles: (a law must authorise it), (the law must serve a proper state purpose), and (the means must be necessary and the ). FRT deployed against a protesting crowd fails at the first hurdle before the other two are even reached—there is no law to test for , because there is no law at all.
But even a hypothetical statute authorising FRT at protests would face a problem of a distinctive kind. Ordinary in India has developed around targeted measures—phone tapping under the , for instance, requires an order directed at a specific person or line, reviewed by a competent authority. Facial recognition at a public assembly inverts that logic entirely. It does not target a suspect; it processes every face in a crowd of thousands indiscriminately, converting each into a biometric template capable of being matched, stored, and cross-referenced, regardless of whether that person has done anything to attract police attention beyond attending a protest. The inquiry cannot be conducted after the fact, individual by individual; it has to be built into the design of any permissible framework through , , and before deployment—none of which currently exist.
This indiscriminate character also gives the challenge its second constitutional dimension: the on . A citizen who knows that attending a protest means being biometrically logged into a police database, for an unknown duration and unknown future use, faces a real disincentive to attend at all. Constitutional courts across jurisdictions have recognised that surveillance need not result in arrest or prosecution to cause injury; the awareness of being watched itself reshapes conduct, and speech chilled by surveillance is speech denied.
A Comparative Signal Worth Reading
India is not alone in confronting this question, and the comparative record is instructive. In , the held in that police use of live facial recognition technology, though not inherently unlawful, violated the under the European Convention because the legal framework governing it left too much discretion to individual officers over who could be scanned and where. The court also found the force had failed in its duty to assess whether the technology's error rates disproportionately affected people by sex or race. The parallels to the Indian situation are not exact, but the structural lesson transfers cleanly: it is the absence of a clear, public, —not the existence of the technology as such—that renders its use unlawful. A state cannot outsource the boundaries of a fundamental-rights-infringing power to .
What the Courts Are Now Being Asked to Decide
The Rahim petition asks the to restrain FRT deployment at peaceful assemblies until legislates. That framing is doing real constitutional work: it does not ask the Court to permanently outlaw the technology, but to insist that 's guarantee of be honoured before the technology is used at all. This is the correct sequencing. Courts are generally reluctant, and rightly so, to design surveillance frameworks from the bench; that is a legislative task, requiring calibration of retention periods, oversight mechanisms, and accuracy standards that shift with the technology itself. But courts are well placed to declare that, in the interim, an with no statutory basis cannot continue merely because no one has yet stopped it.
If the Court engages with this case on its merits, it has the opportunity to do for what Puttaswamy did for the itself: supply the missing doctrinal architecture before , entrenched through years of quiet deployment, becomes politically and administratively irreversible. The Jantar Mantar protests may have ended with the Education Minister's resignation. The constitutional question they raised has not ended with them, and how it is answered will shape what it means to assemble in public in India for a long time to come.
Conclusion
The two pending petitions are not merely technical challenges to a specific police operation. They confront a deeper issue: whether the Indian State can build a surveillance infrastructure that operates outside the framework of law, answerable to no statute and no independent oversight. The answer, the petitioners argue, must be a resounding no. The courts now have the opportunity to affirm that the , as articulated in Puttaswamy , applies to crowds as much as to individuals, and that the on assembly is as real as any physical restraint. For legal professionals, this is a moment to watch—not just for the fate of FRT, but for the architecture of fundamental rights in the age of algorithmic governance.
