BNSS 2023: Investigation, FIR, Search and Seizure

India’s BNSS rules for FIRs, forensic scene visits, search recordings and police reports, with the conditions and limits of each procedure.

By Reviewed by Sourabh

Last updated:

The Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) is India’s criminal-procedure code. It generally commenced on 1 July 2024, replacing the CrPC subject to its savings provisions. It addresses information to police, investigation, searches, medical examinations, reporting and proceedings. It is distinct from substantive offences under the BNS and evidence rules under the BSA.

For forensic work, several provisions connect the legal process with records of what was collected and examined. Important examples include section 173 on information about cognizable offences, section 176(3) on forensic-expert attendance under its conditions, section 105 on recording specified searches and seizures, and section 193 on the police report.

This is an Indian-law lesson. It explains statutory roles and practical documentation questions without treating a notification-dependent provision as uniformly implemented in every state. In other countries, consult the corresponding local authority; good scientific handling does not itself create a legal power to search or sample.

By the end of this topic you will be able to:

  • Distinguish an FIR, police report, forensic report and custody-related time limit.
  • Read the threshold and State Government notification condition in section 176(3).
  • Explain the recording scope of section 105 without assuming every discrepancy automatically excludes evidence.
  • Keep original information, electronic receipt, transfer and signature times distinct.
  • Connect exhibits, handling records and examination results while preserving the correct legal authority and applicable procedural code.
Key terms
BNSS 2023
Bharatiya Nagarik Suraksha Sanhita, 2023: India’s criminal-procedure code, with 531 sections. Check its commencement, savings and applicable conditions for the particular proceeding.
Zero FIR
A common term for registering information despite the receiving police station not having territorial jurisdiction. Section 173(1) addresses information irrespective of the area of the offence; the section does not prescribe a universal number prefix.
e-FIR
Electronic communication is recognised in section 173(1). It is taken on record on being signed within three days by the person giving it; an online complaint and a completed FIR should not be assumed identical.
Section 176(3) BNSS
A provision for forensic-expert attendance, collection and videography for the specified offence category, operating from the State Government’s notified date within the statutory period.
Section 105 BNSS
A provision requiring audio-video recording of the search or taking possession covered by its wording, including the seizure list and witness signatures, and forwarding the recording without delay to a specified magistrate.
Charge sheet (Section 193)
The police report on completion of investigation. Do not confuse section 193 with the custody and release provisions in section 187 or impose one universal deadline on all laboratory work.

BNSS 2023: Key Changes to Criminal Investigation Procedure

A procedural concordance helps locate rules, but it does not prove that every requirement is unchanged. Identify the governing provision, the case’s procedural status and any relevant local implementation before applying an old form or citation.

QuestionBNSS referencePractical distinction
Information about cognizable offences173Information received, recording, signature and territorial transfer are distinct events.
Forensic-expert scene provision176(3)Check the offence category and notified implementation.
Recording specified searches and seizures105Read the scope and forwarding requirement, not an assumed universal camera protocol.
Police investigation search185 / 186Check authority, grounds, territorial arrangements and records.
Custody-related limits187Different from a universal laboratory or investigation deadline.
Police report193Connect relevant documents and exhibits with the completed investigation.
Repeal and savings531Pending matters need their own transition analysis.

CrPC citations are not automatically obsolete merely because a document is written after July 2024. Section 531 preserves the CrPC for specified matters pending immediately before commencement. Use the code governing the particular matter and explain a concordance where it helps the reader.

A procedural concordance helps prevent confusion between FIR and final-report section numbers.

For section 176(3), distinguish the general commencement of the BNSS from the State Government notification condition in the subsection. Do not describe the provision as requiring an identical named SOCO team, universal custody handover or immediate nationwide operating model.

FIR Registration under Section 173

Section 173 addresses information relating to cognizable offences, including information irrespective of the area where the offence occurred and information given electronically. Its detailed conditions matter. A portal acknowledgement or emergency call should not automatically be labelled a completed FIR.

  1. Record the Information
    Preserve when and how information was received and what was communicated. Distinguish the occurrence time alleged by the informant from the receipt time.
  2. Identify the Recording Route
    For electronic communication, the statute addresses signature within three days. For an out-of-area report, keep registration and transfer events distinct.
  3. Preserve Identifiers and Copies
    Retain the relevant case identifiers, endorsements and records. Verify administrative numbering and system arrangements locally rather than assume a universal zero prefix.
  4. Connect the Investigation Records
    Link subsequent scene attendance, collections and transfers to the case. A later registration or transfer timestamp does not erase earlier response or handling events.

“Zero FIR” is widely used to describe the out-of-area registration route. Section 173’s territorial wording is the relevant statutory basis here. Do not invent a universal numbering convention or assume that a jurisdictional transfer is the first time information reached police.

There is no single “scene-to-station clock” that replaces all other timestamps. An incident may involve a call, first response, protective action, registration, transfer, expert attendance and collection at different times. Preserve each event and its source so delays and discrepancies can be examined.

Keep the original information time distinct from transfer and signature events.

Electronic records can support a timeline, but a server timestamp is not automatically correct, complete or immune to alteration. Record time zones, clock settings, access controls and provenance where relevant. Investigate a discrepancy with the case diary rather than assume that it automatically invalidates both records.

An FIR, station diary entry and non-cognizable-information record have different purposes. A diary entry can also record events in a cognizable case. Administrative labels do not remove the need to respond to an emergency, preserve evidence or reassess new information under the applicable law.

Forensic Scene Visits under Section 176(3)

Section 176(3) addresses information about an offence punishable with seven years or more. It requires the officer in charge to cause a forensic expert to visit and collect forensic evidence, and to cause videography, from the date notified by the State Government within five years. It also provides for notified use of another state’s facility where the relevant facility is unavailable.

The provision concerns the offence’s punishment category, not the eventual sentence imposed on a convicted person. Identify the actual offence and subsection rather than rely on a broad label such as hurt or robbery. Reassess if the facts or legal classification change.

A defensible operational plan links the applicable legal trigger with the actual response arrangements:

BNSS Section 176(3) contains a seven-year threshold and a state-notification rollout condition.
  • Identify the relevant offence, notification and current dispatch procedure.
  • Record the request, response and attendance times and any limitation or unavailable service.
  • Prioritise life and safety, protect the scene and document necessary interventions.
  • Define collection and recording responsibilities; record who actually handled each item.
  • Coordinate suitable photography, sampling, packaging, sealing and onward transfer.
  • Preserve discrepancies and reasons for decisions rather than infer compliance from a particular job title or signature alone.

Check the actual state notification and service arrangements. An undated list of allegedly compliant states or a claim that most states have a particular 24-hour desk can become misleading. A policy announcement, staffing plan and operating service are different things.

Do not claim an exclusion trend or cite an unnamed High Court order as a universal rule. If a procedural defect is disputed, identify the governing rule, the established facts and the decision’s actual holding. The scientist should disclose the handling and its potential consequences, not predict the court’s response.

The subsection does not state that custody begins only when an expert arrives or that the expert automatically takes command of the inner cordon. Provenance includes earlier recognition, emergency actions, handling and access. Record custody according to what occurred, including transfers between investigators, scene personnel, storage and the laboratory.

The Indian laboratory guide distinguishes institutions and referral arrangements. The BNS guide explains substantive offence references; neither replaces the need to check the particular procedural notification.

Search and Seizure: Section 105 Videography

Section 105 covers recording the search of a place or taking possession of property under the specified chapter or section 185, including the seizure list and witness signatures. It requires forwarding without delay to one of the specified magistrates. Read this scope rather than describe it as an identical rule for every conceivable seizure under every statute.

BNSS provisionSubjectReading point
105Audio-video recording of the specified search / taking possessionIncludes seizure-list preparation and witness signing.
185Search by police officerRead the grounds, recording and other statutory conditions; it is not simply a search-with-warrant section.
186Requiring another station to search and specified urgent cross-boundary searchesRead the territorial and communication conditions.
106Police power to seize certain propertyNot the section heading for searching a suspected stolen-property premises.

Plan a recording that makes the process understandable and connects items with their collection records. Use local lawful procedures for devices, storage, interruptions and onward transmission. The statute’s text is not a substitute for a documented technical workflow.

  • Missing recording: preserve the reason, equipment or storage records and other relevant documentation. Do not invent footage or silently substitute another event.
  • Interrupted or incomplete recording: record the interruption and its cause. Preserve original files and context rather than assemble a misleading continuous narrative.
  • Disagreement with the seizure record: compare identifiers, timing and quantities, retain the discrepancy and investigate it. A correction should have a traceable explanation.

Video and written records are complementary sources, not automatic independent proof that every described event happened. Preserve original files, metadata, handling history and authorised copies. A hash can check a copy against a reference, but it does not establish the recording’s truth or every earlier event.

Independent documentation channels make discrepancies visible for investigation and legal assessment.

Medical examinations have their own provisions: section 51 addresses evidential examination of an arrested person under its conditions; section 52 concerns a person accused of rape; section 53 requires examination soon after arrest and a record of injuries or marks of violence. Section 53 is not merely an examination available on the arrested person’s request.

Keep accused-person examination provisions separate from section 184 on examination of a rape victim, including its consent condition. Sampling needs the appropriate authority, qualified personnel and documentation. Do not infer one universal consent rule for every form of examination.

From Seizure Memo to Section 193 Charge Sheet

Section 193 concerns the police report on completion of investigation. Section 187’s 60/90-day custody and release framework is a different matter; it is not a universal deadline for every FSL report. Section 193 also contains specific investigation and reporting requirements. Avoid declaring every report without a laboratory annexure automatically incomplete for all legal purposes.

  1. Receive the Exhibits
    Check identifiers, seals, condition, documentation and requested examinations. Record discrepancies and resolve acceptance or referral under the laboratory’s procedures.
  2. Record the Examination
    Retain the responsible examiner, methods, observations, results and changes to the exhibit. Keep relevant controls and technical records available for scrutiny.
  3. Report Within Scope
    Explain supported conclusions, uncertainty and limitations. Do not assume the court will read only the opinion or omit material necessary to understand it.
  4. Document Dispatch
    Link the report to the examined exhibits, remaining material and actual recipients. Record dispatch and transfer events.
  5. Connect the Legal File
    The investigator and legal process determine required reports, documents and later material. Preserve the record of what was supplied, when, and what remained pending.
The laboratory report must remain traceable to the collected exhibit throughout the investigation.

Communicate requested dates and any scientific or capacity constraint. A documented priority is not permission to omit quality controls or tailor a result. Do not invent a nationwide backlog length from the existence of custody-related time limits.

If a report is delayed or material is unsuitable, record the reason and communicate through the proper channel. The scientific task and legal consequences of a pending examination require separate assessment; neither follows automatically from a generic deadline slogan.

An examiner asked to explain a report should be able to account for methods, relevant technical records, exhibit provenance and limitations. Section 193 is the police-report provision, not a standalone rule establishing every expert witness’s competence or the admissibility of every opinion.

Procedure and evidence requirements interact throughout the matter; one does not simply stop when the other begins. BSA expert-opinion provisions and relevant BNSS provisions must be read with the governing proceeding. A scientifically useful report can still raise separate authentication, disclosure or other legal questions.

BNSS section 398 concerns State Government witness-protection schemes, rather than sections 215–219. Eligibility and measures depend on the applicable scheme and circumstances. Do not assume a particular job title automatically guarantees protection or that one statutory reference describes every operational step.
