Supreme Court Orders Voice Sample from Ex‑Manipur CM N Biren Singh Amid Forensic Lab Failures

The Supreme Court, frustrated by the inability of central forensic labs to authenticate audio clips allegedly linking former Manipur CM N Biren Singh to ethnic violence, has directed the Union Government to consider obtaining a fresh voice sample from Singh at the National Forensic Science University (NFSU). The Court also urged the petitioner to produce the original recording and hinted at possible referral to a High Court under Article 226, underscoring the challenges of forensic evidence in judicial inquiries.

Supreme Court Orders Voice Sample from Ex‑Manipur CM N Biren Singh Amid Forensic Lab Failures The apex court expressed dissatisfaction with multiple forensic laboratories that could not conclusively verify a 48‑minute audio clip allegedly implicating former Manipur Chief Minister N Biren Singh in the state’s ethnic violence. Consequently, the Court asked the Union Government to explore whether Singh can visit the NFSU in Gujarat to give a fresh voice sample. Key Developments April 6, 2026 – Bench of Justice Sanjay Kumar and Justice K Vinod Chandran questioned why central labs could not produce conclusive forensic findings. The CFSL in Guwahati reported technical limitations, stating the audio was tampered and could not be reliably matched. Earlier orders (Feb 2025, May 2025, Aug 2025, Jan 2026) directed fresh reports from CFSL and later the NFSU , but each report highlighted editing of the clip. Advocate Prashant Bhushan argued the audio was modified to erase the recorder’s voice and sought the original file. The Court hinted at referring the matter to a High Court under Article 226 if necessary. Important Facts • The disputed clip is 48 minutes long and allegedly captures Singh’s statements during the 2024 ethnic clashes in Manipur. • Both the CFSL (Guwahati) and NFSU (Gandhinagar) reported that the audio had been edited using software, rendering speaker‑comparison impossible. • A private lab, Truth Labs, previously certified the tape as authentic, but the Court has not accepted that evidence. • President’s rule was imposed in Manipur shortly after the audio controversy, and Singh resigned a few days before the proclamation. UPSC Relevance 1. Judicial oversight of forensic evidence – Highlights the role of the Supreme Court in ensuring reliability of scientific evidence, a topic under GS2 (Polity) and GS3 (Science & Technology). 2. Federal structure and Centre‑State relations – The case involves the Union Government, central forensic agencies, and a state’s political leadership, illustrating Centre‑State dynamics (GS2). 3. Constitutional provisions – Reference to Article 226 underscores the jurisdictional powers of High Courts, essential for GS2 preparation. 4. Ethnic violence and law‑and‑order – The background of Manipur’s ethnic clashes connects to internal security and governance issues (GS1 & GS2). Way Forward The Union Government should arrange a controlled voice‑sample recording of N Biren Singh at NFSU, ensuring chain‑of‑custody and technical standards. The petitioner must attempt to locate the original, unedited audio, if the source is willing to disclose it without compromising safety. If forensic verification remains inconclusive, the Court may refer the matter to a High Court under Article 226 for a detailed writ petition on evidence admissibility. Strengthening capacity and standard operating procedures of central forensic labs is essential to avoid similar impasses in future investigations. These steps will aid the judiciary in delivering a decisive verdict while reinforcing the credibility of forensic science in India’s legal system.
