High Courts Interpret Section 193(9) BNSS: Pre-Trial Further Investigation Needs No Court Permission

The power of the police to conduct further investigation after filing a charge-sheet has long been a flashpoint between investigative autonomy and judicial oversight. With the enactment of the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), Parliament introduced a seemingly modest proviso to Section 193(9) that requires court permission for further investigation only “during the trial.” This textual change has ignited a debate: did the legislature simply codify the Supreme Court’s earlier mandate of judicial permission, or did it deliberately confine that requirement to the trial stage, leaving pre-trial investigations free of mandatory court approval? Two High Courts have now weighed in, and the Supreme Court’s recent observations have deepened the uncertainty.

The CrPC Position: Text vs. Judicial Interpretation

Under Section 173(8) of the Code of Criminal Procedure, 1973 (CrPC), the police retained the statutory power to conduct further investigation even after submitting a final report. Critically, the provision did not explicitly require prior permission from the Magistrate. The Supreme Court, however, supplied that safeguard through judicial interpretation. In Vinay Tyagi v. Irshad Ali (2013), the Court held that prior leave of the court must be read into Section 173(8) as a necessary implication. This was reaffirmed in Vinubhai Haribhai Malaviya v. State of Gujarat (2019), which further held that the Magistrate’s supervisory power to order further investigation suo motu continued until the commencement of trial.

Thus, by the time the BNSS was enacted, the statutory text and the judicially developed rule were not identical: the CrPC’s plain text did not demand permission, but Supreme Court precedent effectively did.

BNSS’s Calibrated Control

Section 193(9) BNSS retains the basic power of further investigation after forwarding the police report to the Magistrate. The significant departure lies in the proviso:

“Provided that where further investigation is conducted during the trial, such investigation shall be conducted with the permission of the Court trying the case and shall be completed ordinarily within a period of ninety days.”

The placement of the proviso is critical. Parliament did not say that every further investigation after filing the report requires permission. Nor did it attach permission merely to post-cognizance investigation. It selected a particular procedural stage: “during the trial.” On an ordinary textual reading, therefore, the main part governs further investigation generally, while the proviso superimposes judicial and temporal control once the matter has entered trial.

The legislative history offers little clarity. The proviso was present in the original BNSS Bill, but the Parliamentary Standing Committee’s report did not explain why permission was confined to the trial stage. Notably, Rajya Sabha MP N. R. Elango’s dissent flagged the breadth of the further-investigation power, but his note neither proposed an alternative nor explained the choice of phrase “during the trial.” The legislative record thus identifies the concern but does not resolve the interpretive question.

High Courts Draw the Line

The Andhra Pradesh High Court confronted the distinction directly in State of Andhra Pradesh v. Balaji Govindappa (2025). Comparing Section 193(9) with Section 173(8), the Court noted that the BNSS had added a proviso requiring permission for further investigation during trial, but that there was “no mention” of seeking such permission at the pre-trial stage. It further recorded that, in the case before it, trial had admittedly not commenced. The Court therefore refused to treat the proviso as a general permission clause operating immediately upon filing of the charge-sheet. Instead, the language of Section 193(9) was treated as creating a distinction between further investigation generally and further investigation once trial has begun.

The Delhi High Court adopted a similar textual approach in Anuradha @ Chiku v. State (NCT of Delhi) (2026). Justice Sanjeev Narula described the change as a “calibrated control”: Section 193(9) carries forward the principle permitting further investigation, while the newly added proviso requires the permission of the Court when such investigation takes place “during the trial.” On the facts before it, the Court held that the investigation had not reached the stage at which the proviso was triggered. The Sub-headline “During the trial” emerged as the operative phrase.

Supreme Court’s Sidestep

The Supreme Court had an opportunity to settle the matter in Palaniswamy Veeraraja v. State of Karnataka (2026). However, that case arose under the old CrPC, not the BNSS. While comparing the two provisions, the Court expressly observed that “neither Section 173(8) CrPC nor Section 193(9) BNSS generally mandates permission, but that the proviso to Section 193(9) expressly requires permission once trial has begun.” That observation strongly supports a stage-specific reading of the new provision. Yet, the Court proceeded to reaffirm the broader judge-made rule under Section 173(8), ultimately holding that the further investigation before it could not have proceeded without the Magistrate’s permission.

The crucial qualification is that the Court was not required to decide whether the judicially created requirement under Section 173(8) survives unchanged for pre-trial further investigation under Section 193(9) BNSS. Consequently, its observations expose, rather than conclusively resolve, the tension between the old doctrine and the new statutory text.

Unresolved Questions: The Suo Motu Power

A related issue is whether the court may suo motu order further investigation before trial. Under CrPC, Vinubhai clearly held that the Magistrate’s supervisory power does not cease upon taking cognizance and may be exercised suo motu until trial begins. Nothing in Section 193(9) expressly removes that power. The stronger view, therefore, is that Vinubhai continues to govern the court’s power to order pre-trial further investigation. The position becomes less clear once trial has commenced. The proviso expressly contemplates further investigation during trial with the permission of the court trying the case, but it does not state whether that court may itself initiate such investigation suo motu . The text clearly establishes judicial control at the trial stage, but the precise source and extent of a trial court’s power to set further investigation in motion remain open.

Impact on Legal Practice

For practising criminal lawyers and public prosecutors, the immediate takeaway is that pre-trial further investigation under the BNSS does not carry an express statutory requirement of prior permission from the court. This appears to restore a measure of investigative autonomy that had been judicially curtailed under the CrPC. However, until the Supreme Court definitively rules on the matter, prudent investigation officers may still seek court permission to avoid potential challenges. Defence counsel, on the other hand, may continue to argue that Vinay Tyagi and Vinubhai remain binding interpretations of the general power, regardless of the BNSS proviso’s narrow wording.

The ninety-day timeline for trial-stage further investigation is a welcome procedural discipline, but it also raises practical questions: what happens if the ninety-day period is exhausted without extension, or if the investigation uncovers material requiring a supplementary report after trial has ended? Magistrates and trial courts will need to balance the need for completeness with the accused’s right to a speedy trial.

Conclusion

The enactment of Section 193(9) BNSS has undoubtedly altered the statutory framework governing further investigation, but the extent of that change remains unsettled. Two competing interpretations now vie for acceptance: one that treats the proviso as merely codifying the existing judicial requirement of permission (albeit only for the trial stage), and another that reads the proviso as creating a clear dichotomy – no permission needed pre-trial, mandatory permission during trial. The High Courts have leaned toward the latter, while the Supreme Court has left the door open. Until the apex court rules on a case squarely arising under the BNSS, the law will remain in a state of controlled ambiguity, demanding careful advocacy and judicial sensitivity to the facts of each case.
