The High Court of Madhya Pradesh at Jabalpur has dismissed a petition filed by an Assistant Sub-Inspector (ASI) challenging a trial court order that rejected a closure report in a corruption case. The division bench, comprising Justice Anand Pathak and Justice Deepak Khot, ruled that an inconclusive forensic voice examination report does not, by itself, provide sufficient legal grounds for the prosecuting agency to close a criminal investigation initiated under the Prevention of Corruption Act, 1988. The court’s decision reinforces the supervisory authority of a Magistrate to direct further investigation when the initial inquiry is deemed incomplete or unsatisfactory.

The dispute originated from a complaint filed by a local businessman, Karan Gurjar, who alleged that his landlord, Syed Noman Hussain, had engaged in vandalism and unlawful retention of property. The petitioner, then serving as an ASI, was tasked with investigating the matter. It was subsequently alleged that the petitioner demanded a bribe of ₹30,000 to facilitate the investigation and secure the filing of an FIR against the landlord. When the complainant approached the Deputy Superintendent of Police (Dy.S.P.), he was provided with a digital voice recorder to document the solicitation of the bribe. Although a trap was organized, the police were unable to apprehend the petitioner, as he was not present at the police station premises during the intended proceedings.

Following the initial investigation, the state agency submitted a closure report (Khatma No.2/2025) to the Special Judge (PC Act) in Bhopal. The rationale provided for closing the case was twofold: first, the transcript of the recorded conversation allegedly lacked a direct demand for a bribe; and second, the Regional Forensic Science Laboratory (RFSL) in Bhopal reported that it could not provide a definitive opinion on the identity of the speaker due to insufficient speech data and poor audio quality. However, the Special Judge rejected the closure report, citing the need for independent and more robust evidence, and directed the Investigating Officer to obtain fresh voice samples from the petitioner for a secondary forensic examination.

Judicial Scrutiny of Investigating Agency Inaction

In its analysis of the challenge, the High Court scrutinized the limitations of the initial forensic report. The court observed that the RFSL had noted a large degree of intra-speaker variation and suspected a deliberate attempt at voice disguise by the petitioner. Critically, the bench concluded that the failure to reach a conclusion was not proof of innocence, but rather a reflection of inadequate procedural rigor. The court emphasized that the prosecution's decision to close the investigation based on an inconclusive report failed to serve the interests of justice, especially when the case was initiated on the basis of a transcript that contained prima facie evidence of an attempt to solicit an illegal gratification.

As the court noted, "the Magistrate will have ample jurisdiction to give directions to the police, under Section 156(3) , to make a further investigation. That is, if the Magistrate feels, after considering the final report, that the investigation is unsatisfactory, or incomplete, or that there is scope for further investigation, it will be open to the Magistrate to decline to accept the final report."

This ruling underscores the judiciary’s role in ensuring that investigative agencies exercise due diligence. The court highlighted that while the police have the primary authority to form an opinion on whether to prosecute, the trial court is not a mere rubber stamp for such reports. The power to order further investigation under Section 173(8) of the Code of Criminal Procedure is intended to prevent lapses in the administration of justice, particularly in cases involving public corruption.

Forensic Limitations and the Need for Verification

The petitioner argued that the trial court’s direction for fresh voice sampling constituted a "roving inquiry" and violated his protection against self-incrimination under Article 20(3) of the Constitution of India. The petitioner's counsel contended that the lack of direct, clear evidence of a bribe demand in the existing transcript, coupled with the failed trap proceedings, meant that any further collection of samples would be an exercise in futility.

The High Court rejected these arguments, citing established legal precedents. The bench reasoned that directing an accused to provide a voice sample does not infringe upon constitutional safeguards against self-incrimination . The court stated, "From perusal of the FSL report filed in the reference tab of the ERP, this court is of the considered opinion that the sample which was sent to the FSL was inappropriate and insufficient to form an opinion. Therefore, closure report on the basis of such inconclusive evidence does not lead to the conclusion that on the basis of collected evidence no offence is made out."

By emphasizing the difference between an inconclusive investigation and an exhaustive one, the bench clarified that the trial court acted within its legitimate jurisdiction. The order does not compel the police to file a charge sheet against their own discretion, but rather requires them to conduct a more professional and thorough investigation before a final decision to close the case can be legally sanctioned.

The High Court’s intervention highlights the judiciary’s commitment to ensuring that serious corruption allegations against law enforcement personnel are met with rigorous scrutiny. By dismissing the petition, the bench has effectively compelled the investigating agency to return to the process, ensuring that the evidence is gathered with greater accuracy. The matter now rests back with the investigating agency, which is expected to comply with the directive to obtain fresh voice samples, ensuring the subsequent scientific analysis is conducted on clear and sufficient speech data. This move is expected to settle the investigative ambiguity that had previously led to the filing of the closure report, setting a clear procedural path for the resolution of the corruption allegations against the petitioner.
