Introduction:

The Kerala High Court has directed the Union Government and the Unique Identification Authority of India (UIDAI) to facilitate the comparison of fingerprints collected during the investigation of the Sreekrishnapuram double murder case with fingerprints stored in the Aadhaar database. The order, delivered by Justice G. Girish on October 14, 2026, seeks to assist investigators in identifying the persons potentially connected with a brutal double murder that has remained unsolved for nearly a decade. At the same time, the Court expressly clarified that its decision was based on the exceptional facts of the case and must not be treated as a precedent for routinely permitting similar requests in other investigations.

The matter, reported as 2026 LiveLaw (Ker) 579, arose from a petition filed by the Deputy Superintendent of Police, Crime Branch, Palakkad, seeking judicial intervention after the UIDAI declined a request for assistance in comparing crime-scene fingerprints with those maintained in the Aadhaar database. The investigation concerned the murder of a middle-aged couple at Sreekrishnapuram in Palakkad district in 2016. According to the prosecution, the murders were allegedly committed with the intention of robbing the victims.

Despite investigations by the local police and the Crime Branch, the perpetrators had not been conclusively identified. The investigating agency had collected six sample fingerprints from the crime scene and compared them against fingerprints obtained from more than 1,200 individuals. Although the investigation led to Rajendran, whose fingerprint reportedly matched a fingerprint collected at the scene, the exercise did not enable the authorities to identify the offenders responsible for the murders.

Faced with this difficulty, the investigating officer sought assistance from the UIDAI to compare the fingerprints collected during the investigation with biometric records available in the Aadhaar database for Coimbatore, Tamil Nadu. The objective was to identify individuals whose recorded fingerprints corresponded with the prints recovered from the crime scene and thereby provide investigators with potential leads.

The UIDAI did not accede to the request. The authorities opposing the proposed exercise relied on statutory restrictions governing access to Aadhaar information and raised concerns about the technical feasibility of comparing fingerprints collected during a criminal investigation with records maintained in the Aadhaar database. They also warned that allowing such a request could encourage similar applications in numerous other criminal cases, potentially creating a flood of demands for access to sensitive biometric information.

The investigating agency consequently approached the Kerala High Court, seeking an order that would enable the proposed comparison within the legal framework governing Aadhaar information. The central question was whether the restrictions imposed by the Aadhaar (Targeted Delivery of Financial and Other Subsidies, Benefits and Services) Act, 2016, prohibited the requested exercise or whether the statutory provisions permitted a court of the requisite judicial level to direct disclosure of information for a legitimate investigative purpose.

The Court examined Sections 28, 29 and 33 of the Aadhaar Act, particularly Section 33, which deals with disclosure of information in certain circumstances. Section 33 provides a statutory mechanism for disclosure pursuant to an order of a court not inferior to that of a Judge of a High Court, subject to the applicable safeguards. These include an opportunity of hearing for the UIDAI and the Aadhaar number holder concerned, as well as a prohibition against disclosure of core biometric information.

Another important issue concerned the constitutional right to privacy recognised by the Supreme Court in Justice K.S. Puttaswamy (Retd.) v. Union of India. The respondents questioned whether the proposed exercise was compatible with the legal protections governing personal information and biometric data. The High Court considered the relevant conclusions in the privacy judgment and examined whether the proposed fingerprint comparison fell within the restrictions applicable to Aadhaar information.

After hearing the parties, Justice G. Girish allowed the petition. The Court reasoned that the statutory restrictions invoked by the respondents did not prevent the requested disclosure in the circumstances of the case, provided the exercise remained within the limits established by law. It also concluded that the technical objection raised against the comparison had been dispelled.

Importantly, the Court distinguished between identifying the whereabouts of persons whose recorded fingerprints corresponded with the crime-scene prints and obtaining or transmitting their core biometric information. The order contemplated the identification of potential leads for the investigating agency, which could then pursue further investigative steps, including collecting fingerprints from identified persons and comparing them in accordance with the law.

The Court expressly cautioned that the decision should not be treated as a general authorisation for accessing Aadhaar biometric information in criminal investigations. It stated that the order was being made in view of the exceptional facts and circumstances of the particular case and could not be cited as a precedent for following the same course in future matters.

The ruling is significant because it addresses the relationship between criminal investigation, statutory restrictions on biometric information and the constitutional right to privacy. It demonstrates that courts may examine whether a narrowly defined investigative request falls within an applicable statutory exception, while also emphasising that such an exercise must not become an unrestricted route to accessing sensitive personal data.

Arguments of the Parties:

The petition was filed by the Deputy Superintendent of Police, Crime Branch, Palakkad, who sought directions enabling the UIDAI to assist in comparing the fingerprints recovered from the crime scene with the records maintained in the Aadhaar database. The investigating agency’s request arose from the difficulties encountered in identifying the perpetrators of the Sreekrishnapuram double murder despite extensive investigative efforts.

The petitioner relied on the seriousness of the offence and the prolonged failure to identify the culprits. The murders had occurred in 2016, and the investigation had involved the collection and examination of fingerprints from the crime scene. Six sample fingerprints had been collected and compared with fingerprints belonging to more than 1,200 individuals. Nevertheless, the investigating agency had been unable to identify the persons responsible for the offence.

The investigation had led to Rajendran, whose fingerprint reportedly matched one of the fingerprints collected at the crime scene. However, the comparison exercise had not resolved the larger question of who had committed the murders. The investigating agency therefore sought to expand the search by requesting a comparison with fingerprints maintained in the Aadhaar database for Coimbatore, Tamil Nadu.

The petitioner effectively sought access to an additional identification resource that might generate investigative leads unavailable through the earlier comparison exercise. The proposed comparison was intended to assist the investigation rather than replace the ordinary procedures through which the police could subsequently verify the identity and involvement of any person identified.

The investigating agency approached the Court after the UIDAI declined to act on its request. The petitioner sought judicial intervention on the basis that the requested assistance could be examined under the statutory provisions governing disclosure of Aadhaar information. The agency’s position was that the investigation should not be deprived of a potentially useful identification method merely because the requested records were maintained within a regulated biometric database, provided that the exercise was authorised by law.

The petitioner’s request, however, was not simply for unrestricted access to the Aadhaar database. The issue before the Court concerned a specific comparison connected with an identified criminal investigation and a particular set of fingerprints recovered from the crime scene. The agency sought assistance directed towards identifying possible matches and enabling further investigation into a serious offence that had remained unresolved.

The Union Government and the UIDAI opposed the request on legal and technical grounds. One of their principal objections was that the Aadhaar Act restricts the disclosure of information maintained by the UIDAI. They contended that information collected and stored under the Aadhaar framework is subject to statutory protections and cannot be shared merely because a law enforcement agency considers it useful for an investigation.

The respondents relied on the restrictions contained in Sections 28 and 29 of the Aadhaar Act. These provisions regulate the security, use and disclosure of information maintained within the Aadhaar system. According to the respondents, allowing the investigating agency to access biometric records without complying with the statutory framework would undermine the safeguards governing the collection and use of Aadhaar information.

The respondents also raised concerns regarding the technical feasibility of the proposed comparison. They argued that the fingerprints collected during a criminal investigation might not be directly comparable with the fingerprint information stored in the Aadhaar database because the records and methods of collection could differ. The concern was that the comparison might not be technically reliable or feasible in the manner proposed by the investigating agency.

Another substantial objection concerned the potential consequences of granting the petition. The respondents submitted that if the Court permitted the investigating agency to compare crime-scene fingerprints with Aadhaar records, other investigating agencies could seek similar directions in a wide range of criminal cases. This, they argued, could open the door to numerous requests for access to biometric information and place considerable pressure on the statutory protections established by the Aadhaar Act.

The concern was not limited to the particular murder investigation. The respondents effectively argued that a decision permitting such access might be relied upon in subsequent cases, potentially transforming an exceptional request into a recurring method of criminal investigation. They therefore urged the Court to consider the broader implications for the Aadhaar system and the protection of personal biometric information.

The dispute also involved the constitutional dimensions of privacy. Aadhaar records contain sensitive personal information, and the collection, storage and disclosure of such information must be considered in light of the constitutional protection recognised by the Supreme Court. The respondents’ objections reflected the need to ensure that investigative convenience did not displace the statutory and constitutional safeguards governing biometric data.

The Court was consequently required to balance the investigating agency’s need for assistance in a serious and long-pending criminal case against the restrictions governing Aadhaar information. It also had to consider whether the proposed exercise would involve prohibited disclosure of core biometric information or whether the relevant statutory provisions permitted a more limited form of disclosure under judicial supervision.

The rival submissions thus raised three connected questions. The first concerned the scope of the Aadhaar Act’s restrictions on disclosure and the extent to which Section 33 permitted a court to direct disclosure in an appropriate case. The second concerned the distinction between providing identifying information to investigators and transmitting core biometric information itself. The third concerned the effect of the Supreme Court’s privacy jurisprudence and the possibility that allowing the request could encourage similar applications in the future.

These issues required the High Court to examine not only the usefulness of the proposed comparison but also its precise legal character. The question was whether the particular investigative step could be authorised within the statutory framework without creating an unrestricted exception to the protections governing Aadhaar information.

Court’s Judgment:

The Kerala High Court allowed the petition filed by the Deputy Superintendent of Police, Crime Branch, Palakkad, and directed the Union Government and the Deputy Director of the UIDAI to facilitate the requested fingerprint comparison in connection with the Sreekrishnapuram double murder investigation. Justice G. Girish reached this conclusion after examining the relevant provisions of the Aadhaar Act, considering the privacy objections and assessing the distinction between identifying potential matches and disclosing core biometric information.

At the outset, the Court recognised the exceptional circumstances surrounding the case. The murders had occurred in 2016, yet the investigation had not resulted in the identification of the perpetrators despite extensive efforts. The investigating agency had collected six sample fingerprints and compared them with those of more than 1,200 individuals. The proposed Aadhaar comparison was therefore sought after the earlier investigative methods had failed to resolve the case.

The Court considered Sections 28, 29 and 33 of the Aadhaar Act, 2016. Sections 28 and 29 establish protections governing the security, use and disclosure of information maintained under the Aadhaar framework. These provisions must be read alongside Section 33, which deals with disclosure of information in certain cases pursuant to judicial orders.

Section 33 provides a statutory route for disclosure pursuant to an order of a court not inferior to that of a Judge of a High Court, subject to the conditions prescribed by law. The first proviso requires an opportunity of hearing to be given to the UIDAI and the Aadhaar number holder concerned before an order is passed in the relevant circumstances. The second proviso prohibits the disclosure of core biometric information.

The Court explained that the restrictions under Sections 28 and 29 did not operate as an absolute bar against disclosure where the requirements of Section 33 were satisfied. It observed that the statutory restrictions invoked by the respondents had no applicability to a disclosure sought pursuant to an order of a court of the judicial level specified in Section 33, subject to the safeguards contained in that provision.

This interpretation was central to the Court’s decision. The Aadhaar Act establishes restrictions on the use and disclosure of information, but Section 33 also recognises a limited mechanism for judicially authorised disclosure. The existence of statutory confidentiality does not necessarily mean that information can never be disclosed in any circumstances. Rather, disclosure must fall within the applicable legal framework and satisfy the conditions prescribed by the legislature.

The Court then examined the first proviso to Section 33. It observed that the requirement concerning an opportunity of hearing for the UIDAI had been satisfied in the present case. The UIDAI and the relevant authorities had been heard in connection with the petition, and their objections had been considered before the Court issued its direction.

The Court also addressed the requirement concerning the Aadhaar number holder whose information might be involved. It noted that the persons whose fingerprints could potentially match those collected from the crime scene had not yet been identified. Consequently, providing an opportunity of hearing to those unidentified persons could not be accomplished at that stage. The Court treated that aspect of the requirement as inapplicable in the particular circumstances of the request.

This conclusion was tied to the nature of the proposed exercise. The investigating agency did not yet know the identities of the individuals whose fingerprints might correspond with the crime-scene samples. The very purpose of seeking assistance from the database was to generate potential identification leads. Requiring the agency to obtain a hearing from unidentified persons before learning who they were would have presented a practical difficulty in the circumstances of the case.

The Court’s reasoning did not establish that the opportunity-of-hearing requirement could generally be disregarded whenever investigators sought access to Aadhaar information. Rather, it addressed the specific difficulty arising because the individuals potentially associated with the fingerprints had not yet been identified. The order must therefore be read in the context of the limited investigative request and the exceptional circumstances expressly identified by the Court.

The second proviso to Section 33, which prohibits disclosure of core biometric information, was another important consideration. The Court distinguished between providing information that could assist the police in locating persons whose fingerprints matched the crime-scene samples and transmitting the underlying fingerprint, iris or other core biometric data to the investigating agency.

The Court noted that the petitioner had not sought transmission of the fingerprint or other core biometric information itself. Instead, the request was directed towards identifying the whereabouts of persons whose fingerprints matched those collected during the investigation. The proposed exercise would enable the investigating agency to pursue further steps through the legally recognised procedures available in criminal investigations.

As the Court explained, once the whereabouts of persons whose fingerprints matched the crime-scene samples were conveyed to the investigating agency, the police could proceed with the further investigation, including collecting fingerprints from those individuals and undertaking comparisons in accordance with the law. The Court therefore concluded that the prohibition contained in the second proviso to Section 33 did not apply to the particular request before it.

This distinction between identification-related information and the transmission of core biometric data formed a central part of the judgment. The Court did not authorise unrestricted access to the Aadhaar database or permit the investigating agency to obtain all biometric records associated with potential matches. Its decision concerned the limited assistance sought to identify persons who might be relevant to the investigation.

The distinction also reflects the importance of examining the precise nature of a disclosure request rather than treating every form of access to information as legally identical. A request for the underlying biometric data may raise different statutory issues from a request for information that helps an investigating agency locate a person for further lawful investigation. The Court considered the particular form of assistance sought and concluded that it did not fall within the prohibition relied upon by the respondents.

The High Court also considered the respondents’ reliance on Justice K.S. Puttaswamy (Retd.) v. Union of India, the landmark Supreme Court judgment recognising the right to privacy as a constitutionally protected fundamental right. The respondents had argued that privacy protections restricted the proposed collection o use of biometric information.
