👨⚖️ Case Laws on Cybercrime Evidence Collection
Below are more than five important case laws that detail the judicial approach to cyber evidence, its collection, and admissibility:
1. Anvar P.V. v. P.K. Basheer (2014)
Citation: (2014) 10 SCC 473
Court: Supreme Court of India
Issue: Admissibility of electronic evidence under Section 65B
Facts: Audio CDs were produced in court without proper certification.
Judgment:
Overruled previous practice of admitting electronic evidence without certification.
Held that Section 65B certificate is mandatory for electronic records.
Secondary evidence is inadmissible unless compliance with Section 65B is met.
Significance:
Set a rigid standard for digital evidence collection and admissibility.
All digital data must be accompanied by a certificate under Section 65B(4).
2. Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal (2020)
Citation: (2020) 7 SCC 1
Court: Supreme Court of India (Three-judge Bench)
Facts: Election petition involved mobile call recordings and WhatsApp messages.
Judgment:
Reaffirmed Anvar P.V. principle.

Certificate can be issued by any person who is in a position to access and reproduce the data (e.g., service provider or system admin).
Significance:
Reinforced procedural discipline in collecting cyber evidence.
Stressed importance of maintaining the integrity of digital records.
3. State of Delhi v. Mohd. Afzal & Others (2003 Parliament Attack Case)
Court: Delhi High Court / Supreme Court
Facts: Involved seizure of computers and emails sent by the accused.
Judgment:
Court accepted electronic evidence, such as emails and call records, as valid.
However, chain of custody and forensic validation were key to admissibility.
Significance:
Early case where digital forensic practices were applied.
Emphasized the role of expert evidence under Section 45A of the Indian Evidence Act.
4. Sonu @ Amar v. State of Haryana (2017)
Citation: (2017) 8 SCC 570
Court: Supreme Court of India
Facts: SMS records produced as evidence without 65B certification.
Judgment:
Held that courts must not overlook the procedural requirement of Section 65B.
Even if evidence is not objected to at the trial, it cannot be validated retroactively if not properly admitted.
Significance:
Reinforced that illegally or improperly collected cyber evidence is inadmissible.
Encouraged timely objection to unauthenticated digital documents.
5. Tomaso Bruno & Another v. State of U.P. (2015)
Citation: (2015) 7 SCC 178
Facts: Italian nationals were accused of murder. CCTV footage was crucial.
Judgment:
Court accepted that non-production of CCTV footage, despite availability, raised serious doubt on prosecution.
Emphasized the importance of preserving and producing electronic evidence.
Significance:
Set precedent that withholding or mishandling cyber evidence can harm prosecution’s case.
Highlighted the role of CCTV and surveillance footage in criminal trials.
6. State v. Mohd. Haroon (Delhi Riots Case, 2020)
Court: Delhi Trial Court
Facts: WhatsApp chats, videos, and digital records were produced to prove riot conspiracy.

🛡️ Challenges in Cyber Evidence Collection
Volatility of digital evidence – Easily altered or lost.
Encryption and privacy – Law enforcement faces obstacles with encrypted data.
Jurisdiction issues – Servers/data may be located abroad.
Lack of technical training – Many investigators lack cyber forensics skills.
Chain of custody errors – Mishandling makes evidence inadmissible.
✅ Best Practices for Cyber Evidence Collection
Use certified digital forensics tools (like EnCase, FTK, Cellebrite).
Maintain proper chain of custody logs.
Get Section 65B certificates from service providers or IT personnel.
Avoid altering the original device/data.
Preserve metadata and hash values.
🧠 Conclusion
The collection and prosecution of cybercrime evidence requires strict adherence to legal procedures, technical integrity, and judicial scrutiny. Courts have consistently reinforced the mandatory requirements for admissibility under Section 65B and emphasized the importance of digital forensics and expert validation. These judgments shape how cybercrime cases are tried and ensure fairness, authenticity, and reliability in digital investigations.
