Overview
- The Court directed that the entire 48-minute recording, all admitted voice samples of N. Biren Singh, and every audio file furnished by the petitioner be sent to NFSU Gandhinagar, with an expedited report to be filed in sealed cover.
- In November 2025, NFSU told the Court the clips it had received showed signs of tampering and were unfit for voice comparison, prompting judicial concern about incomplete material being sent.
- The petitioner Kuki Organisation for Human Rights Trust says the full 48-minute transcript was on the case record and alleges only short, edited clips were earlier forwarded for testing, while seeking a court-monitored probe.
- Additional Solicitor General Aishwarya Bhati said the state obtained the full recording only after the last hearing, after which the bench instructed that the complete material be transmitted to the lab.
- Petitioners state the total audio runs about 56 minutes but only 48 minutes were filed to protect a whistleblower’s identity, as the case (W.P.(C) No. 702/2024) examines alleged links to the 2023 Manipur violence that killed at least 260 and displaced over 59,000.
