The Delhi High Court has ruled that directing an individual to provide a voice sample for investigative purposes does not breach the constitutional protection against self-incrimination under Article 20(3), nor does it amount to an unlawful invasion of privacy.
The Court made it clear that a voice sample is not the same as forcing an accused to testify. According to the ruling, such a direction is a procedural aid to investigation rather than a compelled statement. While acknowledging that privacy is a fundamental right, the Court underlined that it is not absolute and may give way when the State has a legitimate interest in preventing and investigating crime.
These observations came while dismissing a challenge filed by Kanpur-based businessman Moin Akhtar Qureshi against a trial court order requiring him to submit voice samples to be matched with intercepted phone calls from 2013–14.
Qureshi’s name had earlier figured in a high-profile internal dispute within the investigating agency involving its former top officials, a backdrop that added public attention to the case.
The matter traces its origins to surveillance carried out by the Income Tax Department between October 2013 and March 2014, followed by searches at Qureshi’s premises in February 2014. Based on intercepted telephone conversations and Blackberry Messenger exchanges, a complaint was later lodged, culminating in the registration of a case in 2017 under provisions of the penal law and anti-corruption statutes.
Before the High Court, Qureshi argued that the intercepted calls were outdated, unlawfully obtained and inadmissible, citing alleged violations of Supreme Court guidelines on phone tapping and the absence of mandatory certification under the Evidence Act. He further claimed that compelling him to provide a voice sample amounted to testimonial compulsion barred by the Constitution.
The Court was unconvinced. It rejected the argument that giving a voice sample forces an accused to incriminate himself and found no legal flaw in the trial court’s direction. As a result, the High Court lifted an interim protection granted in November 2021, which had required the voice sample report to be kept in a sealed cover and barred its use.
Concluding that there was no illegality or abuse of process, the Court dismissed the petition, clearing the way for the investigating agency to rely on the voice comparison as part of its probe.
