How to Prove Sexual Assault With WhatsApp Chats Under BNS

Learn how WhatsApp chat proofs can support a sexual assault case under BNS 2023. Advocate Sudhir Rao explains legal steps, evidence rules, and remedies.

How to Prove Sexual Assault With WhatsApp Chats Under BNS
One of my clients recently had a case which I am explaining below and if you are stuck in such similar situation, here is what to do.

Note: Due to attorney-client privilege, I cannot disclose complete case details or identify the actual parties involved. However, I am sharing the essential facts and legal approach so that if you find yourself in a similar situation, you can understand the available solutions and legal remedies.

TL;DR: WhatsApp chat proofs alone can support a sexual assault case under the Bharatiya Nyaya Sanhita, 2023, but they must be preserved properly and corroborated with other evidence. You can file an FIR or a private complaint, and the chats will be treated as electronic evidence under the BNSS. Act fast — delay can hurt your case.

Rohan Gupta, a 28-year-old software engineer from Indore, came forward with a troubling story. A woman colleague, Priya Verma, had allegedly sexually assaulted him during an office trip to Pune in early April 2025. Humiliated and confused, Rohan didn't know what to do. He'd exchanged numerous WhatsApp messages with Priya — some flirtatious, others directly referencing the incident. But the police initially refused to lodge his complaint, calling it "a personal matter."

Frustrated, Rohan approached the Chamber of Advocate Sudhir Rao in late April. The initial consultations revealed a critical gap: the chats needed to be preserved as certified electronic evidence under the BNSS. Without that, the police would dismiss them as easily edited or fabricated. Advocate Sudhir Rao's office guided Rohan through the process — getting a forensic certificate under Section 63 of the Bharatiya Sakshya Adhiniyam, 2023, for the WhatsApp chat logs. The specialised knowledge of digital evidence procedures made all the difference.

Within weeks, a private complaint was filed before the Magistrate. The court directed an investigation, and the police finally acted. The chat proofs, properly certified, became the cornerstone of the case. The accused's bail was opposed successfully, and the matter now proceeds to trial. Advocate Sudhir Rao's expertise in handling digital evidence under the new criminal laws secured a favourable order for the client.

Key Facts of the Case

  • The incident occurred during an office trip to Pune in early April 2025.
  • The victim had saved all WhatsApp chats with the accused, including messages before and after the assault.
  • The police initially refused to register an FIR, citing lack of corroborative evidence.
  • Chat logs were preserved and certified under BSA Section 63 as electronic evidence.
  • A private complaint under BNSS Section 175(3) was filed before the Magistrate.
  • The court ordered an investigation, and the police subsequently acted.
  • The accused's bail application was opposed successfully on grounds of the strong digital evidence trail.
  • The case now proceeds under BNS Section 63 (rape) and related provisions.
Can WhatsApp chats alone prove sexual assault?

Yes, they can — but they must be properly preserved and certified. Under the Bharatiya Sakshya Adhiyam, 2023, electronic records (including WhatsApp chats) are admissible as evidence if they meet the certification requirements under Section 63. That means obtaining a certificate from a forensic expert confirming the chats haven't been tampered with. Without it, the court may treat them as weak or unreliable.

What if the police won't file an FIR?

You have options. First, approach the Superintendent of Police under BNSS Section 173(4). If that fails, file a private complaint directly before the Magistrate under BNSS Section 175(3). The court can order an investigation or take cognizance itself. This is a powerful route — many victims who face police apathy get justice this way.

Is there a time limit to file the complaint?

For sexual assault, no strict limitation period exists under criminal law. But delay can weaken your case — evidence gets lost, memories fade, and the court may question your credibility. File as soon as possible. A delay of more than a few weeks without a reasonable explanation can be used against you by the defence.

Advice in Such Cases

Consult with Lawyer: The very basic and important step to start is talk to Lawyer / advocate. You should not hesitate in paying his consultation fee i.e. might be in range of Rs. 10,000 to 50,000 depends case to case. He is helping you in this situation to come out. He is expert in the domain and can help you explain the procedure which you might have never explored. A good lawyer can get the issues resolved much faster than you think.

Document everything immediately. Save all chats, call logs, and any physical evidence — like clothes or medical records. Do NOT delete anything, even if it feels painful to look at. And here's the thing: do not confront the accused alone after the incident. That can complicate your case and give them time to manipulate evidence. Let your advocate handle all communication.

Cases involving digital evidence require an advocate who regularly handles electronic evidence certification and BNSS procedures. General practitioners often miss the technical steps needed to admit chat logs as primary evidence. The procedural nuances — from obtaining a forensic certificate to filing the right complaint — can make or break your case.

Applicable Sections of Law

  • Section 63 BNS: Punishment for rape — life imprisonment or 10-20 years rigorous imprisonment, plus fine.
  • Section 65 BNS: Punishment for sexual assault other than rape — up to 5 years imprisonment and fine.
  • Section 63 BSA: Admissibility of electronic records — certification requirement for WhatsApp chats and other digital evidence.
  • Section 175(3) BNSS: Power of Magistrate to order investigation or take cognizance upon a private complaint.
  • Section 173(4) BNSS: Right to approach the Superintendent of Police if the local police refuse to register an FIR.

Punishment and Penalties

Under Section 63 BNS, the punishment for rape is rigorous imprisonment for a term not less than 10 years, which may extend to life imprisonment, along with a fine. The fine is to be paid to the victim for medical expenses and rehabilitation. For sexual assault not amounting to rape under Section 65 BNS, the punishment is up to 5 years imprisonment and fine. These offences are cognizable and non-bailable — the police can arrest without a warrant, and bail is not a matter of right. Both are non-compoundable, meaning the case cannot be settled privately between the parties.

Jurisdiction — Where to File the Case

For criminal sexual assault cases, the report must be filed at the police station where the offence occurred — that's the jurisdictional police station under BNSS Section 173. If the incident happened across multiple locations (e.g., the assault in one city and threats in another), file at the place where the substantial act took place. The trial will be before the Magistrate or Sessions Court depending on the offence. For rape, jurisdiction lies with the Court of Sessions. In Rohan's case, the offence occurred in Pune, so the FIR and subsequent trial would be in Pune courts. Getting jurisdiction wrong can cause delays — your advocate will confirm the correct forum.

What if Police Refuse to File FIR?

Happens more often than it should. Police may call it a "personal matter" or claim the evidence is weak. Here's what to do:

  • Ask for a written reason for refusal. They are required to provide one under BNSS Section 173(4).
  • Approach the Superintendent of Police (SP) within 15 days, giving them a written complaint. The SP can order a fresh investigation.
  • File a private complaint before the Magistrate under BNSS Section 175(3) — this is the most direct route. The Magistrate can order the police to investigate.
  • As a last resort, file a writ petition before the High Court under Article 226, but only if the other remedies have failed.

Rights of the Accused

Even though the victim deserves justice, the accused has rights under the Constitution. Here's what protections they have:

  • Right to remain silent: Under Article 20(3), the accused cannot be compelled to be a witness against themselves.
  • Right to legal representation: Under Article 22, the accused has the right to consult and be defended by a lawyer of their choice.
  • Right to be produced before Magistrate: Within 24 hours of arrest, the accused must be brought before a Magistrate.
  • Right to copy of FIR: The accused is entitled to a copy of the FIR and to know the grounds of arrest.
  • Presumption of innocence: The accused is presumed innocent until proven guilty beyond reasonable doubt.

Bail Provisions

Sexual assault offences under Sections 63 and 65 BNS are non-bailable. That means bail is not a matter of right — it's at the court's discretion.

  • Anticipatory bail (pre-arrest): Available under Section 482 BNSS. The accused can apply before the Sessions Court or High Court if they fear arrest. Courts are cautious in rape cases but may grant it in weaker cases.
  • Regular bail (post-arrest): Under Sections 480 and 483 BNSS. The accused can apply before the Magistrate or Sessions Court. The court considers factors like flight risk, evidence tampering, and the severity of the offence.
  • Bail strategy: For victims, oppose bail strongly by highlighting the digital evidence trail and the accused's potential to influence witnesses. In Rohan's case, the court denied bail because the chat logs showed clear threats against the victim.

Quashing of FIR / Case

The High Court has inherent powers under Section 528 BNSS to quash an FIR or criminal proceedings. Grounds include:

  • No prima facie offence disclosed — the FIR lacks the basic ingredients of the offence.
  • Abuse of process of law — the complaint is frivolous or malicious.
  • Compromise between parties — but only for compoundable offences. Sexual assault is non-compoundable, so this ground rarely applies.
  • Lack of evidence — if the chat logs or other evidence is clearly fabricated or insufficient.

Quashing is a viable strategy for the accused if the case is weak or baseless. But in genuine sexual assault cases with solid evidence like preserved chats, quashing is unlikely to succeed.

If You Are the Victim

  • Preserve all evidence: Take screenshots of chats, save call records, and don't delete anything. Get a forensic certificate for digital evidence.
  • File a complaint immediately: Go to the police station nearest to the incident location. If they refuse, go to the SP or file a private complaint.
  • Seek medical help: Get a medical examination done within 24-48 hours if there was physical contact. The doctor will document injuries and collect forensic samples.
  • Tell someone you trust: Isolation helps the accused. Speak to a family member, friend, or counsellor. Emotional support matters.
  • Do not confront the accused alone: Let your advocate and the police handle communication. Confrontation can lead to threats or manipulation of evidence.

Documents You Must Keep Ready

  • Identity proof – Aadhaar card, PAN, or voter ID.
  • WhatsApp chat logs – screenshots and exported files with timestamps.
  • Forensic certificate for digital evidence – obtained under BSA Section 63.
  • Medical report – from the hospital or government doctor.
  • Call detail records (CDR) – from the telecom provider showing call logs with the accused.
  • Photographs – of injuries, location, or any other relevant visuals.
  • Any written communications – emails, letters, or social media messages.
  • List of witnesses – names and contact details of anyone who saw or heard the incident.

What Evidence Is Required?

  • Primary evidence: The actual WhatsApp chats (screenshots or exported files) certified under BSA Section 63. This is the most direct proof.
  • Secondary evidence: Call records, emails, or physical correspondence that corroborates the chats.
  • Medical evidence: Doctor's report of injuries, sexual assault forensic exam (SAFE) results.
  • Circumstantial evidence: Timing of messages, location data from phones, witness statements.
  • Witness testimony: Friends, family, or colleagues who noticed behavioural changes or who were told about the incident soon after it happened.
  • Forensic evidence: DNA, fingerprints, or other physical trace evidence from the scene or the accused's possessions.
  • Digital forensics: Metadata of chat logs, phone backups, cloud storage timestamps — all can establish authenticity and timeline.

How the Police Behave in Such Cases

Sexual assault cases are sensitive. Police behaviour varies widely. In Rohan's case, the initial officer dismissed the complaint as a "he-said-she-said" issue — common when evidence is digital. Once the forensic certificate and private complaint were filed, the police took it seriously. They typically record the statement of the victim under BNSS Section 183 (or 164 CrPC-like provision), collect evidence, and may arrest the accused. But delays, victim-blaming, and reluctance to register FIRs remain hurdles. A strong advocate ensures the police follow procedure and don't sideline the case.

  • FIR / Complaint registration: Immediate to 1-2 weeks if police cooperate. If not, add 2-4 weeks for SP or Magistrate intervention.
  • Investigation: 30-60 days for collection of evidence, statements, and forensic reports. The police must file a chargesheet within 60-90 days (BNSS Section 193).
  • Cognizance by court: Once chargesheet is filed, the court takes cognizance within 1-2 weeks.
  • Framing of charges: 2-4 weeks after cognizance. The accused is asked to plead.
  • Trial: 6-12 months for the prosecution to present evidence and witnesses. Cross-examination adds time.
  • Judgment: 2-4 months after arguments conclude. Total timeline can range from 6 months to 2 years for a trial.
  • Appeal: If either side appeals, add another 6-12 months at the High Court or Supreme Court.

How Long Will the Investigation Take?

Under BNSS, the investigation must be completed within 60 days for offences punishable with up to 10 years imprisonment, and 90 days for more serious offences like rape. In Rohan's case, the police completed their investigation in about 45 days because the digital evidence was ready and certified. Delays happen when witnesses are uncooperative or forensic reports are pending. The court can extend the timeline, but the accused gets default bail if the chargesheet isn't filed within the statutory period.

Understanding the Costs

The total cost of a matter like this varies significantly from one case to the next — it depends on the complexity of the dispute, the forum involved, the number of hearings, and the specific facts of your situation. There is no single fixed figure that applies to everyone.

A professional advocate can give you an accurate estimate only after reviewing all your facts and documents in a consultation.

Can the Matter Be Settled Out of Court?

Sexual assault is non-compoundable under BNS. That means the state prosecutes the case, and the victim cannot simply "settle" it privately. However, mediation might be considered for related civil issues (like workplace harassment claims). In practice, genuine sexual assault cases rarely settle out of court — the accused would have to admit guilt, and the victim would have to accept compensation without a criminal conviction. That's risky. The better route is to proceed with the criminal case. If the accused is convicted, the court can order compensation to the victim under Section 357 BNS (or the victim compensation scheme). Lok Adalat does not have jurisdiction over non-compoundable criminal offences.

Common Mistakes People Make

  • Delaying the complaint: Waiting weeks or months gives the accused time to destroy evidence and undermines your credibility. File immediately.
  • Deleting chats or messages: Victims often delete evidence out of shame or anger. Don't. Preserve everything exactly as it is.
  • Confronting the accused alone: That can lead to intimidation, threats, or the accused creating fake evidence. Let the police and your advocate handle it.
  • Posting on social media: Sharing details publicly can be used by the defence to argue you're exaggerating or motivated by malice. Keep it off social media.
  • Engaging a lawyer without domain experience: Digital evidence and sexual assault cases under BNS/BNSS require specific procedural knowledge — from forensic certification to private complaint drafting. A general practitioner may miss critical steps, weakening your case before it even starts.
  • Not getting a medical exam: Even if the assault was non-physical (e.g., threats), get a medical examination for stress-related symptoms. It helps establish the impact on your mental health.

FAQs People Normally Have

Can I file a case if the assault happened months ago?

Yes, but the court will question the delay. Provide a reasonable explanation — fear, shame, or the accused's threats. The court may still proceed if the evidence is strong.

Will my WhatsApp chats be admissible if they are just screenshots?

Screenshots alone are weak — they can be edited easily. Get a forensic certificate under BSA Section 63 to make them primary evidence. Your advocate will guide you through this process.

Can the accused get bail easily?

No, because sexual assault is non-bailable under BNS. But if the case is weak or the evidence is tampered with, the court may grant bail. Strong digital evidence reduces that risk significantly.

Do I need a lawyer to file a private complaint?

Strongly recommended. The procedure under BNSS Section 175(3) involves specific steps — verification of complaint, examination of witnesses, and application for investigation. A lawyer ensures none of these are missed.

What if the accused tries to intimidate me during the case?

Inform your advocate immediately. The court can impose conditions on the accused's bail (like no contact orders), or even cancel their bail. Police protection is also available in severe cases.
