# Supreme Court Orders Disclosure of NFSU Findings on Disputed Biren Singh Audio Files

The Supreme Court has mandated the federal government to release a forensic report regarding leaked audio clips attributed to former Manipur Chief Minister N. Biren Singh. While the Union government claims the recordings were manipulated, petitioners cite independent tests showing a 93% voice match.

## Key takeaways

- The Supreme Court ordered the Union government to share NFSU forensic findings with the Kuki Organisation for Human Rights.
- Federal representatives claim the audio clips allegedly featuring Biren Singh were manipulated and should lead to the petition's dismissal.
- Counsel for the NGO cite private lab results showing a 93% voice match and plan to contest the government's forensic findings on October 5.
- The legal battle stems from ethnic violence in Manipur that has claimed over 260 lives and displaced thousands since May 2023.

## Contested Evidence in Manipur Violence Probe

Legal proceedings concerning the ethnic conflict in Manipur took a sharp turn as the Supreme Court directed the Union government to provide the Kuki Organisation for Human Rights with a report from the National Forensic Sciences University (NFSU). This document examines audio recordings that allegedly implicate former Chief Minister N. Biren Singh in the state's prolonged unrest.

## Discrepancies in Forensic Analysis

During the hearing before a bench led by Justice Sanjay Kumar, Additional Solicitor General Aishwarya Bhati asserted that the NFSU analysis identified clear manipulation within the recordings. Bhati, representing both federal and state authorities, argued that even the initial copies provided by a whistleblower showed signs of alteration, prompting a formal request for the court to dismiss the NGO's petition.

Advocate Prashant Bhushan, acting for the petitioner, challenged these findings. Bhushan pointed to separate evaluations conducted by Truth Labs, which reportedly identified a 93% match between the audio clips and the former Chief Minister's voice. Although Bhushan agreed to maintain the confidentiality of the NFSU report, he signaled his intention to formally contest its conclusions during future proceedings.

## Procedural History and Data Integrity

The court had previously expressed concern regarding the integrity of the evidence submitted for testing. In December 2023, judges questioned why only specific segments, rather than the complete leaked recordings, were originally sent for examination. This followed a November 2025 affidavit which confirmed that the petitioners had submitted only select clippings for initial forensic review. The court subsequently mandated the submission of 'first generation' copies to ensure a comprehensive national lab analysis.

## Why It Matters

This case seeks the establishment of an independent Special Investigation Team (SIT) to scrutinize the leadership's role in the violence that erupted in May 2023. The conflict between the Imphal valley-based Meitei and the hill-based Kuki communities has resulted in more than 260 deaths and the displacement of thousands of residents. The resolution of this evidentiary dispute is central to determining if a high-level probe will be launched.

## Key Facts

- The Supreme Court set the next hearing for October 5 to review responses to the NFSU report.
- The Union government maintains the audio clips are 'clearly manipulated' based on national lab findings.
- Petitioner NGO Kuki Organisation for Human Rights claims private testing shows a 93% voice match.
- More than 260 individuals have died in the ethnic violence since its inception in May 2023.
- The court previously scrutinized the petitioners for submitting only 'select clippings' rather than full audio files.
