1. The Expanded Definition of Documentary Evidence (Section 2(1)(e))
Under Section 2(1)(e) of the BSA 2023, 'Document' has been expansively redefined to explicitly encompass electronic and digital records:
What Constitutes an Electronic Record under BSA 2023?
- Electronic emails, SMS communications, server logs, and instant messaging chat histories (WhatsApp, Telegram).
- Audio recordings, telephone intercepts, digital dictaphone voice recordings, and video clips.
- CCTV surveillance footage, body-worn camera recordings, and drone footage.
- Computer printouts, optical disks (CD/DVD), USB flash drives, solid-state drives (SSD), and cloud server backups.
- Cryptographic tokens, blockchain ledger entries, and digital transaction receipts (UPI, NEFT, RTGS logs).
2. Section 61: Admissibility of Electronic or Digital Records
Section 61 of BSA 2023 establishes the foundational principle that nothing in the Adhiniyam shall apply to deny the admissibility of an electronic or digital record in evidence on the sole ground that it is an electronic or digital record. It has the same legal effect, validity, and enforceability as any paper document, provided the conditions under Section 63 are satisfied.
3. Primary vs Secondary Electronic Evidence: The Landmark Doctrine
One of the most litigated questions in Indian evidence law is whether the electronic medium produced before the court is "Primary" or "Secondary" evidence. In the seminal Three-Judge Bench judgment of the Supreme Court in Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal (2020) 7 SCC 1, the Court established clear boundaries that continue under BSA 2023:
Primary vs Secondary Classification
Primary Evidence (Section 57 BSA): Where the original electronic device itself (e.g. the original smartphone, the original hard drive, or the memory card upon which the video was first recorded) is produced directly into the custody of the court for examination, it is primary evidence. In such instances, no certificate under Section 63 is strictly necessary, provided the integrity of the hardware is unimpeached.
Secondary Evidence (Section 63 BSA): Where copies, printouts, extracts, USB copies, or CD/DVD transfers created from the primary device are produced in court, they are secondary evidence. The production of a valid statutory Certificate under Section 63 BSA is a non-negotiable mandatory condition precedent. Without this certificate, secondary electronic evidence is legally inadmissible.
4. The Section 63 BSA Statutory Certificate: Mandatory Requisites
Section 63 of BSA 2023 (corresponding to Section 65B of the repealed Evidence Act) mandates that any information contained in an electronic record printed on paper, stored, recorded, or copied in optical or magnetic media shall be deemed to be a document if the following four cumulative conditions are satisfied:
- Lawful Control: The computer output was produced during the period over which the computer was used regularly to store or process information by a person having lawful control over the use of the device.
- Regular Feeding: During said period, information of the kind contained in the electronic record was regularly fed into the computer in the ordinary course of the said activities.
- Proper Operation: Throughout the material part of the period, the computer was operating properly; or if not, the period of inoperation did not affect the accuracy of the electronic record.
- Accurate Reproduction: The information reproduced in the electronic record reproduces or is derived from information fed into the computer in the ordinary course.
5. Cyber Forensics & Chain of Custody Protocol
In criminal trials involving cyber fraud, extortion, or POCSO electronic evidence, defense and prosecution alike must scrutinize the forensic chain of custody:
- Seizure in Faraday Pouches: The seized mobile handset or digital device must be immediately powered off and secured in a radio-frequency shielded Faraday bag or static-free packaging to prevent remote wiping or signal alteration.
- Cryptographic Hash Value Calculation: Before any examination, the investigating officer or forensic examiner must create a bit-stream disk image (clone) of the device and calculate its cryptographic hash value (SHA-256 or MD5). If the hash value of the image does not match the seized storage medium, tampering is presumed.
- Working on Mirror Copies: Forensic examination must NEVER be conducted on the original suspect hard drive; it must always be conducted on an authenticated forensic clone.
6. Call Detail Records (CDR) and Tower Location Data
Telecommunication data is frequently relied upon in bail hearings and criminal trials before Rajasthan courts to establish alibi or presence:
CDRs obtained from cellular service providers must be accompanied by a Section 63 BSA certificate signed by the Nodal Officer of the telecom company. A bare printout without the authorized Nodal Officer's stamp and signature carries zero evidentiary weight in law.
Frequently Asked Questions on Digital Evidence
In Arjun Panditrao, the Supreme Court held that while the certificate should ideally be filed along with the chargesheet or plaint, the trial court possesses discretion to permit the filing of the Section 65B (now Section 63 BSA) certificate at a subsequent stage prior to the conclusion of the trial, provided no serious prejudice is caused to the accused.
Bare printouts of WhatsApp screenshots are inadmissible secondary evidence unless accompanied by a certificate under Section 63 BSA signed by the person in lawful possession of the phone from which the screenshot was taken, or unless the original mobile device is produced before the court for physical verification.
