Electronic Evidence in Criminal Case
With the new Bhartiya Sakshya Adhiniyam (BSA), 2023, and the Bhartiya Nagarik Suraksha Sanhita (BNSS), 2023, India has brought its approach to digital evidence up to date, while still keeping some important traditional safeguards in place.
1. Recognition and Parity
Now, items such as emails, server logs, cloud data, blockchain records, CCTV footage, WhatsApp chats, and social media posts all count as “documents” under Section 61 of the BSA. Basically, the law sees digital evidence just like any other written document—that’s a big shift and fits how investigations and trials actually work today.
2. Certificates and Admissibility
If you’re dealing with secondary electronic evidence—like printouts, screenshots, or exported logs—you need a certificate under Section 63 (which replaces the old Section 65B). This certificate comes from someone responsible for the device or system and confirms:
- What device or system was involved
- That the system was working properly and was used regularly
- How the output was created
- The output’s accuracy and authenticity
If you’ve got the original device or storage media, you can use standard evidence methods—seizure memos, witnesses, or forensic experts—without needing a certificate.
3. Procedural Safeguards and Chain of Custody
BNSS Section 105 now requires audio-video recording of searches and seizures. That makes the evidence trail clearer and helps settle any disputes about tampering. Best practices include:
- Isolating devices (using aeroplane or Faraday mode)
- Documenting device details, storage info, and hash values
- Imaging devices with write-blockers
- Keeping detailed forensic logs
4. Judicial Discretion
Courts care more about getting to the truth than sticking rigidly to procedure. Judges can accept statements explaining digital content if needed, but full transcripts aren’t compulsory. If a certificate is generated or produced late, as long as the court allows, it’s not a big problem. Supreme Court cases like Anvar, Shafhi, Arjun Panditrao Khotkar, and Kailash v. State of Maharashtra already give guidance—make sure digital records are properly authenticated, don’t put up unnecessary hurdles.
5. Emerging Challenges
The law doesn’t shy away from new problems:
- With end-to-end encryption, there’s a tough balance between tracing messages and protecting privacy.
- Getting data from abroad often takes government cooperation through MLATs.
- AI-generated content and deepfakes are huge risks, so there’s a push to back up digital evidence with metadata, hashes, and expert validation.
- Any evidence gathering now has to line up with the Digital Personal Data Protection Act, 2023.
6. Practical Implications
- Investigators need to handle digital evidence carefully—hash everything, encrypt when needed, use forensic imaging, and don’t skip the proper certificates.
- Prosecutors and complainants should submit secondary digital evidence with accurate Section 63 certificates and expert reports, avoiding unnecessary oral evidence.
- Defence lawyers should look hard at the chain of custody and the process, challenging any non-original evidence missing the right certificates.
- Judges need to balance flexibility with principle, allow explanations where they help, and only order retrials for serious missteps.
7. Key Takeaways
BSA 2023 updates evidence law for today’s world—it doesn’t overturn everything, just makes things clearer and the process smoother. Certification is simpler, but still the heart of admissibility for digital evidence. It’s about authenticity, integrity, and protecting the chain of custody, not just ticking technical boxes. Courts can make room for technological change, aiming for reliability while keeping things fair.
Conclusion
With these new laws, Indian courts now treat digital evidence the same as old-style documents. Certificates are mainly for secondary digital copies; the chain of custody process is front and centre. It’s a big step forward, but the real difference will come down to how well judges, investigators, and lawyers put it all into practice. For digital evidence to truly stand up in court, it needs to be collected and certified the right way—no artificial hoops, just solid, rights-respecting work that matches the digital world we live in.
