Section 193(9) BNSS: further investigation does not end with the first police report

Section 193(9) of the Bharatiya Nagarik Suraksha Sanhita, 2023 expressly permits further investigation even after the police have forwarded their report to the Magistrate under Section 193(3). If additional oral, documentary, electronic, forensic or other evidence is later obtained, the officer in charge may forward a further report or further reports to the Magistrate.

That further report is commonly described in practice as a supplementary charge-sheet or supplementary police report. But the expression “further investigation” has a precise legal meaning. It supplements the earlier investigation; it is not the same as wiping out the earlier investigation and starting again from zero.

The Supreme Court has reinforced the judicial-control requirement in 2026. In Pramod Kumar v. State of Uttar Pradesh, 2026 INSC 120, the Court held that after submission of the final police report, the investigating agency cannot proceed with further investigation without obtaining leave of the Magistrate or Court concerned. The principle was reiterated in Palaniswamy Veeraraja v. State of Karnataka, decided on 26 May 2026.

The practical result is that Section 193(9) must be read as a power to supplement the evidentiary record under judicial supervision, especially after the first police report has already entered the court process.

What does Section 193(9) actually provide?

Section 193(9) states, in substance, that nothing in Section 193 prevents further investigation after a police report under Section 193(3) has been forwarded to the Magistrate. If additional evidence is obtained, the officer in charge must submit a further report or reports, and the procedural requirements applicable to the original police report apply, as far as may be, to the further report.

The proviso creates an additional safeguard once the case has reached the trial stage:

further investigation during trial may be conducted only with the permission of the court trying the case;
it should be completed within 90 days; and
the 90-day period may be extended only with the permission of the court.

Primary statutory source: Bharatiya Nagarik Suraksha Sanhita, 2023 — India Code.

Further investigation, fresh investigation and reinvestigation are different

Concept	Meaning	Legal character
Further investigation	Collection of additional evidence after an earlier police report	Supplements the earlier investigation and report
Supplementary report	Further police report filed after additional evidence is obtained	Read with the earlier report; does not ordinarily erase it
Fresh investigation / de novo investigation	Starting investigation afresh as though the earlier investigation did not exist	Much more exceptional; ordinary Magistrate power is not the same as power to order de novo investigation
Reinvestigation	Investigating the matter again in substitution of the earlier investigation	Legally distinct from further investigation and subject to stricter limits

The distinction is important because a police agency cannot use the label “further investigation” to nullify a judicially filed report and secretly replace the earlier case theory with an entirely new investigation outside the statutory framework.

What happens after the first charge-sheet or final report is filed?

The first report under Section 193(3) brings the investigation record before the Magistrate. Depending on the report, the court may then consider cognizance, process, supply of documents, discharge, committal and trial.

For the broader framework of the original police report, see What Is a Charge Sheet in India? Meaning, Contents, Time Limit and Procedure Under BNSS.

Further investigation under Section 193(9) does not automatically suspend every later procedural step. The investigating agency should therefore disclose the status of the further investigation and seek appropriate judicial directions where the pending investigation may materially affect cognizance, charge or trial.

Supreme Court 2026: Pramod Kumar v. State of Uttar Pradesh

Pramod Kumar v. State of Uttar Pradesh, 2026 INSC 120, decided on 4 February 2026, directly examined whether police could undertake further investigation after submission of the final report without obtaining leave of the Magistrate or Court.

The Supreme Court answered the question against unilateral police action. The Court reaffirmed the line of authority flowing through Vinay Tyagi v. Irshad Ali, (2013) 5 SCC 762, and held that the investigating agency ought to seek permission from the court before conducting further investigation after submission of the police report.

The judgment is particularly important because it expressly referred to the BNSS equivalent—Section 193(9)—while deciding the issue under the earlier Section 173(8) CrPC framework.

Supreme Court judgment: Pramod Kumar v. State of Uttar Pradesh, 2026 INSC 120.

Supreme Court 2026: Palaniswamy Veeraraja v. State of Karnataka

In Palaniswamy Veeraraja v. State of Karnataka, decided on 26 May 2026, the Supreme Court again held that although the statutory text does not in terms say that express permission is required before every post-report further investigation, judicial precedent has developed that requirement as a safeguard.

The Court treated permission of the concerned Magistrate as a necessary part of the lawful further-investigation process after a closure or final report has already been filed.

This reinforces a practical proposition: after the police report has entered the court record, the investigating agency should not treat the case as remaining under purely internal police control.

Judgment: Palaniswamy Veeraraja v. State of Karnataka.

Does police need permission before trial has started?

The proviso to Section 193(9) expressly requires permission of the trial court where further investigation is conducted during trial. The 2026 Supreme Court authorities go further in practical effect: once a police report or closure report has already been filed, the investigating agency should obtain leave of the concerned Magistrate or Court even if trial has not yet formally commenced.

This is consistent with the judicial-control principle developed under Section 173(8) CrPC and carried into Section 193(9) BNSS jurisprudence.

Why court permission matters

After a police report is filed, several legal consequences may already have followed:

the Magistrate may have taken cognizance;
summons may have been issued;
the accused may have appeared;
documents may have been supplied;
a discharge application may be pending;
the case may have been committed to the Court of Session;
charges may have been framed; or
trial may already be underway.

Unsupervised further investigation at this stage can destabilise the judicial process. Court permission allows the judge to regulate timing, prevent abuse, protect the accused and complainant, and ensure that supplementary material is brought on record transparently.

Can further investigation continue after cognizance?

Yes. Taking cognizance does not by itself extinguish the statutory power of further investigation. The earlier CrPC jurisprudence consistently recognised that further investigation may continue after cognizance, and Section 193(9) BNSS preserves that structure.

But the fact that further investigation remains legally possible does not mean the police may proceed without judicial oversight after the report has already been filed.

Can further investigation continue after charges are framed?

Potentially yes, because Section 193(9) expressly contemplates further investigation even during trial. But once trial has begun, the proviso is explicit: permission of the court trying the case is mandatory.

The court may consider:

why additional investigation is necessary;
whether the proposed steps are genuinely supplementary;
whether the request is being made to fill a lacuna after the prosecution case has weakened;
the age of the case;
prejudice to the accused;
impact on witnesses already examined;
whether the investigation can be completed within the statutory 90-day period; and
whether the trial should proceed, be partly deferred or be otherwise regulated.

The 90-day rule during trial

The proviso to Section 193(9) introduces a significant BNSS safeguard: where further investigation is conducted during trial, it is to be completed within 90 days.

The period is not absolutely inflexible because the court may extend it. However, extension itself requires judicial permission. This creates a structured timeline and prevents an open-ended investigation from indefinitely paralysing a trial.

A prosecution seeking extension should ordinarily explain:

what steps were completed during the first 90 days;
what remains outstanding;
why the delay occurred;
whether delay is attributable to the accused or third parties;
what definite additional period is required; and
how prejudice to the pending trial will be minimised.

Can a supplementary charge-sheet add new accused?

Yes, where further investigation lawfully reveals material against persons not earlier sent for trial. But the supplementary report itself does not automatically establish guilt or compel the court to summon every person named by the police.

The court must independently examine the material and apply the relevant cognizance and process provisions.

If a person is sought to be added after the trial has advanced, other procedural provisions may also become relevant depending on the stage and the manner in which the new material emerges.

Can a supplementary charge-sheet add new offences?

Yes. Further evidence may reveal a different or additional offence. The investigating agency may place that material before the court in the supplementary report.

However, the court remains the authority that ultimately decides the legal charge to be framed. A police opinion in a supplementary charge-sheet does not by itself amend a judicial charge already framed without the court applying the appropriate procedural provisions.

Can the police change their earlier opinion?

Further investigation may lead the investigating agency to a different evidentiary assessment. But the earlier report does not disappear merely because the police later change position.

The ordinary concept of further investigation is cumulative. The court is entitled to examine the earlier report, the supplementary report and the entire material together.

This becomes especially important where the police first filed a closure report and later seek to prosecute, or first sent an accused for trial and later claim that the person should not be prosecuted.

Closure report and further investigation

A closure report does not permanently end the possibility of further investigation. The Magistrate may reject the closure report, take cognizance on the material already collected, or order further investigation.

But once the closure report is filed, the police cannot simply treat it as an internal document and restart investigation unilaterally. The 2026 Supreme Court authorities reinforce that court permission is required.

Can the Magistrate direct police to file a charge-sheet?

No. This is different from ordering further investigation.

In Brajesh Kumar @ Birjesh Kumar Singh v. State of Bihar, decided on 13 July 2026, the Supreme Court reaffirmed that when police file a closure report, the Magistrate has three principal options:

accept the closure report and close the proceedings;
disagree with the police conclusion and take cognizance on the material disclosed in the report; or
direct further investigation.

What the Magistrate cannot do is compel the investigating officer to file a charge-sheet contrary to the police officer’s own investigative opinion. The formation of the police opinion remains with the investigating officer, while the ultimate judicial decision on cognizance belongs to the court.

Judgment: Brajesh Kumar @ Birjesh Kumar Singh v. State of Bihar.

Can a superior police officer recall or cancel a filed charge-sheet?

Once the police report has been filed before the Magistrate, a superior police officer should not purport to administratively recall, withdraw or cancel the report as if it had never entered the court record.

The lawful route is through further investigation under Section 193(9), supplementary reporting and judicial supervision. This reflects the shift from purely administrative investigation control to a process in which the court has already acquired seisin of the police report.

What is the role of Section 193(4)?

Section 193(4) permits a superior police officer, in cases covered by a State Government direction, to receive the police report through the prescribed channel and, pending orders of the Magistrate, to direct the officer in charge to make further investigation.

This power operates in the statutory context before the Magistrate has acted on the report. It should not be confused with a general power of superior police officers to nullify or withdraw a report after it has been judicially filed and acted upon.

Supplementary charge-sheet is not a device to defeat default bail

Section 193(9) permits lawful further investigation, but it does not authorise the prosecution to file a skeletal or legally incomplete first report merely to defeat an accrued right to default bail and then complete the real investigation later.

The default-bail question depends on whether a legally sufficient police report was filed within the applicable statutory detention period and on the governing Supreme Court jurisprudence.

For the detention framework, see Police Remand vs Judicial Custody Under BNSS: Section 187 and Default Bail.

What documents should accompany the supplementary report?

Section 193(9) applies Sections 193(3) to 193(8), as far as may be, to the further report. Depending on the nature of the additional evidence, the supplementary filing may therefore include:

additional witness statements;
forensic reports;
electronic records;
device-extraction reports;
banking or transaction records;
medical or scientific evidence;
supplementary seizure or recovery documents;
additional expert material;
details of newly identified accused; and
an updated police opinion.

The material should be indexed and supplied to the accused in accordance with the applicable document-supply provisions where the prosecution proposes to rely upon it.

Can the accused demand copies of supplementary material?

Yes, where the prosecution proposes to rely on the supplementary report and accompanying material, the accused’s statutory right to receive the relevant police report, witness statements and relied-upon documents remains engaged.

Late supply of supplementary material can affect the defence’s ability to argue discharge, challenge cognizance, cross-examine witnesses or prepare for trial. The defence should therefore seek adequate preparation time where substantial new evidence is introduced.

Can further investigation be ordered on the complainant’s request?

Yes, the complainant or victim may place material before the Magistrate showing that the investigation is incomplete, biased or has ignored important evidence. The court may then consider whether further investigation is warranted.

But further investigation is not automatic merely because the complainant disagrees with the police conclusion. The request should identify specific investigative omissions, documents, witnesses, electronic records or contradictions requiring examination.

Can the accused seek further investigation?

An accused may point out serious investigative gaps or exculpatory evidence, but the statutory and precedential framework is more cautious when the request effectively asks the court to supervise the manner of investigation for the accused’s benefit.

The correct remedy depends on the stage and nature of the omission. In some cases, the stronger route may be discharge, summoning of defence material at the appropriate stage, cross-examination, production of defence evidence, or a constitutional challenge where investigation is demonstrably unfair.

Further investigation versus filling lacunae in the prosecution case

A court should distinguish genuine discovery of new evidence from an attempt to repair weaknesses exposed during trial.

Factors indicating legitimate further investigation may include:

new forensic material becoming available;
discovery of a new device or account;
identification of an additional participant;
new documentary evidence from a third-party authority;
fresh scientific evidence; or
material that could not reasonably have been obtained earlier.

By contrast, an application made only because cross-examination exposed weaknesses in an already-known issue requires closer scrutiny.

What should the prosecution’s permission application contain?

A properly reasoned application for further investigation should ordinarily identify:

the FIR and case number;
the date of the original police report;
whether cognizance has been taken;
the present stage of proceedings;
the new information or evidentiary development;
the precise investigative steps proposed;
why those steps were not completed earlier;
the likely time required;
whether trial-stage 90-day limits apply; and
how the supplementary report will be placed before the court.

What should the accused examine when permission is sought?

The defence should review:

whether the application identifies genuinely new material;
whether the proposed investigation is actually a de facto reinvestigation;
whether the investigation is being used to delay the trial;
whether witnesses already examined will be prejudiced;
whether the prosecution is trying to fill a known evidentiary gap;
whether the request is within the 90-day trial-stage period;
whether earlier judicial orders are being indirectly circumvented;
whether the investigating agency has explained its earlier omission; and
whether any interim protection is needed before new coercive steps are taken.

Can the trial continue while further investigation is pending?

There is no single automatic answer. The trial court has to manage both processes consistently with fairness and efficiency.

In some cases, trial may continue because the additional investigation concerns a limited collateral issue. In others, proceeding immediately may prejudice one side because the supplementary evidence could materially alter the prosecution case, charge or witness sequence.

The trial court may therefore regulate adjournments, witness examination and supply of documents depending on the facts.

Can a supplementary report override discharge already granted?

A final judicial order of discharge cannot ordinarily be treated as though it never existed merely because police later collect more material. The prosecution must follow the legally available appellate, revisional or other statutory route, and any effect of newly discovered evidence must be examined in light of the finality and scope of the earlier judicial order.

Further investigation is a statutory investigative power; it is not a universal mechanism for bypassing final judicial decisions.

Can further investigation happen after acquittal?

Once there is a final acquittal, principles of finality, double jeopardy and the statutory appellate framework become central. Section 193(9) should not be read as a free-standing power to nullify an acquittal and restart prosecution of the same offence.

Any post-acquittal investigation issue requires examination of the precise offence, whether a distinct offence or offender is involved, the appellate status and constitutional protections.

Section 193(9) and electronic evidence

Further investigation is increasingly used where digital evidence becomes available after the first police report, including:

mobile extraction reports;
cloud records;
email data;
bank and UPI trails;
location data;
CCTV enhancement;
call-detail records;
device-forensic reports;
cryptocurrency tracing; and
foreign-platform responses.

Where digital material is added through a supplementary report, the prosecution should preserve source integrity, chain of custody and statutory admissibility requirements. Section 193(3) itself now requires the police report to state the sequence of custody of an electronic device involved in the case.

Frequently asked questions

Can police investigate further after filing the charge-sheet?

Yes. Section 193(9) BNSS expressly permits further investigation after the first police report, subject to the judicial-control principles laid down by the Supreme Court.

Is court permission required for further investigation?

Yes, after the police report has been filed, the 2026 Supreme Court decisions in Pramod Kumar and Palaniswamy Veeraraja reinforce that the investigating agency should obtain leave of the concerned Magistrate or Court. During trial, the proviso to Section 193(9) expressly requires permission of the trial court.

How long can further investigation continue during trial?

Section 193(9) provides a 90-day period for further investigation during trial, subject to extension with the permission of the court.

Is a supplementary charge-sheet a new charge-sheet?

It is a further police report that supplements the earlier report. The earlier report ordinarily remains part of the record.

Can a supplementary charge-sheet name new accused?

Yes, where further investigation produces material against additional persons. The court must independently consider whether cognizance or process should issue.

Can the Magistrate order the police to file a charge-sheet after a closure report?

No. The Magistrate may take cognizance independently or order further investigation, but cannot compel the investigating officer to form a particular police opinion and file a charge-sheet.

Can police reopen a closure report without the Magistrate?

Not lawfully as a unilateral post-report exercise. Once the closure/final report is filed before court, further investigation should proceed with the concerned court’s leave.

Can further investigation be used after trial has started?

Yes, but only with permission of the trial court and subject to the 90-day statutory framework and any extension granted by the court.

Does a supplementary charge-sheet cancel the first report?

No. Further investigation ordinarily supplements rather than erases the earlier investigation and report.

Conclusion

Section 193(9) BNSS preserves the investigating agency’s ability to collect genuinely additional evidence after submission of the first police report, but it does not create an uncontrolled power to reopen, replace or rewrite the case outside the court process.

The 2026 Supreme Court authorities make the controlling principle clear: once the police report has been filed, further investigation must operate under judicial supervision. During trial, Parliament has made that safeguard explicit and has added a 90-day completion framework, extendable only with the court’s permission.

For accused persons, complainants and prosecutors alike, every supplementary investigation should therefore be tested against five questions: what new evidence emerged, when did it emerge, was court permission obtained, is the exercise truly “further” rather than de novo investigation, and has the supplementary material been brought on record without prejudicing the pending judicial process.

This article is for general legal education and information only. It is not solicitation or case-specific legal advice. The applicable procedure depends on the date of the FIR, whether CrPC or BNSS applies, the stage of cognizance or trial, special statutes, prior judicial orders and the precise nature of the proposed further investigation.
