Every criminal trial in India pivots on a single document: the police report, commonly called the charge sheet. For decades, Section 173 of the Code of Criminal Procedure (CrPC) governed how that document was filed, what it must contain, and what happens when police fail to file it on time. Since July 1, 2024, that provision has been repealed and replaced by the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023.
If you are a practicing advocate, law student, accused person, or complainant, understanding the section 173 CrPC equivalent in BNSS is no longer optional. It is foundational. The new provision, Section 193 BNSS, carries forward the essence of the old law while introducing significant structural changes around timelines, electronic evidence, forensic mandates, and further investigation. Missing any of these changes can cost an accused their liberty or cost a complainant their case.
This guide breaks down every aspect of Section 193 BNSS in plain, actionable terms.

Defining the New Section: 193 BNSS
Section 193 BNSS is the direct, statutory successor to Section 173 CrPC. Both provisions share the same core purpose: they require the officer in charge of a police station to forward a report to the Magistrate once investigation is complete.
However, the BNSS does not simply renumber the old provision. It rewrites it with three clear upgrades:
- Embedded time limits. Under the old CrPC, time limits for filing the charge sheet were derived from Section 167 CrPC through judicial interpretation. Section 193 BNSS embeds those timelines directly into the statutory text, removing ambiguity.
- Mandatory electronic evidence protocol. For the first time, the charge sheet must document the sequence of custody of any electronic device involved. This chain of custody requirement is a new statutory obligation with no equivalent in the CrPC.
- Structured further investigation. The power to conduct further investigation after a charge sheet is filed now operates under judicial supervision with a clear 90-day cap during trial, a restriction that did not exist under Section 173(8) CrPC.
The substance of the charge sheet obligation remains the same. What changes is the accountability framework built around it.
Strict Time Limits for Filing the Final Report
The most practically critical aspect of Section 193 BNSS, for both prosecution and defense, is the time limit for filing the charge sheet after arrest.
The law prescribes two specific windows:
- 60 days from the date of arrest for offences punishable with imprisonment up to 10 years.
- 90 days from the date of arrest for offences punishable with death, life imprisonment, or imprisonment exceeding 10 years.
These are not soft targets or administrative deadlines. They are hard statutory limits tied directly to the accused’s personal liberty. Failure to file within these windows activates the absolute right to default bail under Section 187 BNSS.
Additionally, Section 193(2) BNSS introduces a separate two-month timeline for completing the preliminary inquiry stage before the investigation formally begins in notified cases. This is distinct from the 60/90-day charge sheet deadline and applies to a different phase of the process.
Courts have consistently held that the filing clock runs from the date of arrest, not from the date of remand or the date of the FIR. Defense practitioners must verify the exact date of arrest at the outset of every custody matter.
The Absolute Right to Default Bail (187 BNSS)
Section 187 BNSS (replacing Section 167 CrPC) enshrines one of the most powerful rights available to an accused person in Indian criminal procedure: the right to default bail, also called statutory bail or compulsive bail.
The rule is straightforward. If the police do not file a complete charge sheet within the prescribed 60 or 90-day period, the accused in custody acquires an indefeasible right to be released on bail. The Magistrate has no discretion to refuse this bail once the conditions are met.
Three critical points govern how this right operates in practice:
- Timing is everything. The right to default bail must be exercised before the charge sheet is filed. If the police file the charge sheet on day 89 and the accused applies for default bail on day 91, the right is permanently extinguished. Filing a bail application early, the moment the deadline passes, is essential.
- An incomplete charge sheet does not preserve the right. The Karnataka High Court has clarified that once a report satisfying the requirements of a final report is filed, the right to default bail stands extinguished, even if further investigation is pending or supplementary documents are yet to be filed.
- Further investigation is not a workaround. The Delhi High Court has firmly held that Section 193(9) BNSS, which permits further investigation, operates in a completely separate field from Section 187(3) BNSS. Filing an incomplete charge sheet to defeat the accused’s bail right is judicially recognized as an abuse, and courts have the power to intervene in individual cases.
Mandatory Contents of a Valid Police Report
A charge sheet filed under Section 193 BNSS is only legally valid if it contains all mandatory particulars specified under Section 193(3). The Supreme Court has directed, in the case of Dablu Kujur v. State of Jharkhand, that investigating officers must strictly comply with all content requirements.
Section 193 BNSS Charge Sheet Statutory Checklist
A valid charge sheet under Section 193(3) BNSS must include the following:
- Names of the parties involved in the case
- Nature of the information or FIR
- Names of all witnesses examined during investigation
- Whether an offence appears to have been committed and, if so, by whom
- Whether the accused has been arrested
- Whether the accused has been released on bail and the conditions imposed
- Whether the accused has been forwarded in custody under Section 170 BNSS
- Whether sanction for prosecution has been obtained or is required
- The sequence of custody of any electronic device involved in the offence (new mandatory item under Section 193(3)(i) BNSS, with no equivalent in CrPC)
This final item deserves special attention. In any case where a mobile phone, computer, digital storage device, or similar item is part of the evidence, the charge sheet must now trace every hand through which that device passed from seizure to court. A charge sheet that omits this chain of custody narrative in an electronic evidence case is facially defective.
Integration of Electronic Evidence and Forensics
Section 193 BNSS marks a decisive shift in how Indian criminal procedure treats digital evidence. The BNSS was drafted against the backdrop of a rapidly digitizing economy and a sharp rise in cyber-related offending. The statutory changes reflect that reality.
Three specific developments under BNSS are critical for practitioners:
Electronic Submission of Charge Sheets. Section 193(3) BNSS explicitly permits the police report to be filed electronically through encrypted digital communications. This provision has no equivalent in the CrPC and is intended to eliminate paperwork delays, reduce opportunities for physical document tampering, and speed up the transmission of reports to Magistrates in remote areas.
Mandatory Forensic Evidence for Serious Offences. Under the BNSS framework, forensic evidence collection is now compulsory for offences carrying a punishment of seven years or more. This is a structural change that affects how investigations must be conducted and documented before the charge sheet is filed.
Chain of Custody Documentation. As noted above, the sequence of custody for electronic devices is now a mandatory charge sheet content item. This directly incorporates digital forensic standards into the statutory framework for police reports, aligning Indian law with international best practices in cyber evidence handling.
Further Investigation: The 193(9) BNSS Power
After a charge sheet is filed, the investigating agency does not lose all ability to pursue new evidence. Section 193(9) BNSS preserves the power of further investigation, but hedges it with judicial controls that did not exist under the old CrPC.
Under Section 193(9) BNSS:
- Further investigation can be conducted even after cognizance is taken by the court.
- During trial, further investigation requires express court permission.
- Once permitted, further investigation during trial must be completed within 90 days, extendable only with the court’s leave.
- Any supplementary charge sheet filed as a result must be forwarded to the court.
The Supreme Court, in Ramachandran v. R. Udhayakumar, confirmed that even after investigation is complete under Section 193 BNSS, the police retain the power of further investigation. However, this power is specifically limited to pursuing new evidence or tracing additional accused persons. It cannot be used to redo the entire investigation.
Further vs. Re-Investigation
| Aspect | Further Investigation (193(9)) | Re-Investigation / Fresh Investigation |
| Permissibility | Allowed under BNSS | Not permitted without court order |
| Stage | Post-charge sheet, even post-cognizance | Cannot be initiated by police unilaterally |
| Court Permission Required | Yes, during trial | Requires High Court direction |
| Scope | New evidence, additional accused | Entire investigation redone |
| Output | Supplementary charge sheet | Fresh charge sheet |
Judicial Scrutiny at the Time of Filing
When a charge sheet is filed, the receiving Magistrate does not simply file it and issue summons. Section 193 BNSS contemplates an active judicial role at the point of receipt.
Upon receiving the police report, the Magistrate has three options:
- Take cognizance of the offence disclosed and proceed with issuing process against the accused.
- Disagree with the police report and, treating it as a closure report, take cognizance of the offence independently and issue process.
- Direct further investigation under Section 193(9) BNSS if the report appears incomplete or unsatisfactory.
This three-way power is constitutionally significant. The Magistrate is not a passive recipient of the police report. They exercise independent judicial judgment at the threshold stage. A Magistrate who takes cognizance based on a charge sheet must have applied their mind to the contents. Mechanical or automatic cognizance is a jurisdictional error that can be challenged.
When a supplementary charge sheet is later filed, the Supreme Court has held that the Magistrate must consider both the original charge sheet and the supplementary report jointly before deciding whether sufficient grounds for trial exist.
Handling B-Summaries and Closure Reports
Not every police investigation ends in a charge sheet against an accused. Where the police form the opinion that no offence has been committed or that the evidence is insufficient to proceed, they file a final report recommending closure. In practice, these are often called B-Summary reports or undetected case reports.
When a closure report is filed, the complainant has the right to file a protest petition, expressing disagreement with the police conclusion. The Magistrate must then consider the protest petition along with the police report.
The Magistrate’s options after receiving a closure report mirror their options after receiving a charge sheet. They may accept the closure report, disagree and take cognizance independently, or direct further investigation under Section 193(9) BNSS. A complainant who files a well-drafted protest petition can effectively restart an investigation that the police have abandoned.
Defense practitioners should note that a B-Summary does not permanently bar prosecution. If new evidence emerges, the police can file a charge sheet in the same case.
Tactical Defenses Against Defective Charge Sheets
A defective charge sheet is not just a procedural inconvenience. Properly identified and argued, it can be the foundation for securing default bail, obtaining discharge, or getting the entire proceedings quashed. Every defense advocate handling a BNSS matter should know the following three strategies.
Scrutinize the Filing Clock
The very first task in any custody matter is to establish the precise date of arrest and calculate the 60 or 90-day deadline. Do not rely on the police or the court’s record. Independently verify the date from the remand order, the FIR, and the custody register. If the charge sheet was filed even one day after the applicable deadline, and the accused has not yet applied for bail, file the default bail application under Section 187 BNSS immediately. This right is statutory and absolute, and courts cannot deny it on merits once the deadline is crossed and the bail application is moved before charge sheet filing.
Demand Strict Total Compliance (Section 230 BNSS)
Once a charge sheet is filed and cognizance is taken, Section 230 BNSS requires the Magistrate to supply the accused with copies of all documents sent by the police along with the report. The 60-day clock for filing a discharge application under Section 262(1) BNSS runs from this supply date. Insisting on complete document supply is not a formality. It locks in your discharge deadline and ensures the defense has full access to the investigation record before the discharge hearing.
In any case involving electronic evidence, scrutinize the charge sheet against the mandatory checklist under Section 193(3) BNSS. If the sequence of custody for an electronic device is missing, the charge sheet is facially defective. This can be raised before the Magistrate at the cognizance stage or in a quashing petition under Section 528 BNSS.
Launch the Aggressive Discharge Petition (Section 250/262 BNSS)
Where the charge sheet is filed on time but the material placed before the court does not disclose a prima facie case, the accused has the right to seek discharge before charges are formally framed:
- In Sessions cases: File the discharge petition under Section 250 BNSS within 60 days from the date of commitment under Section 232 BNSS.
- In Warrant cases on police report: File the discharge petition under Section 262 BNSS within 60 days from the date of document supply under Section 230 BNSS.
The discharge petition must demonstrate that even accepting the prosecution’s case at face value, no reasonable inference of guilt arises. Cite the specific deficiencies in the charge sheet, the absence of mandatory forensic evidence where applicable, and any chain of custody gaps in electronic evidence. A well-argued discharge petition filed promptly is one of the most effective tools in the defense arsenal under the BNSS.
Frequently Asked Questions
What is the Section 173 CrPC equivalent in BNSS?
Section 193 BNSS is the direct replacement for Section 173 CrPC, effective from July 1, 2024, and governs the filing of the police report (charge sheet) upon completion of investigation.

What is a B-Summary report and how does a complainant challenge it?
A B-Summary is a police closure report stating no offence was committed. A complainant can challenge it by filing a protest petition before the Magistrate, who may then take independent cognizance or direct further investigation.
Within how many days can an accused file a discharge petition under BNSS?
In Sessions cases, within 60 days of commitment under Section 232 BNSS. In warrant cases on police report, within 60 days from document supply under Section 230 BNSS.
Final Thoughts
The transition from Section 173 CrPC to Section 193 BNSS is not a cosmetic renumbering. It represents a deliberate legislative choice to rebuild the charge sheet framework around accountability, timeliness, and modern evidentiary standards. The mandatory chain of custody requirement for electronic devices, the explicit embedding of the 60 and 90-day filing deadlines, the judicial supervision of further investigation, and the electronic filing option collectively transform how police reports are prepared, filed, and scrutinized.
For defense advocates, the BNSS creates new pressure points that a prepared lawyer can exploit: the filing clock, the electronic evidence checklist, the document supply obligation, and the discharge petition window. For prosecutors, the BNSS creates new compliance obligations that cannot be ignored without jeopardizing the case.
The charge sheet under Section 193 BNSS is both the starting line of a trial and the finish line of an investigation. Mastering this provision means mastering the hinge point of every criminal case filed in India today.
