Judicial Interpretation Of Admissibility Of Digital Data
1. Introduction: Admissibility of Digital Data
Digital data refers to information stored, transmitted, or received in electronic form. In legal terms, it includes:
Emails
SMS messages
Digital photographs and videos
Data from computers, mobile phones, social media, cloud storage, and servers
The admissibility of digital evidence in India is governed primarily by:
Indian Evidence Act, 1872 (IEA)
Section 65A: Admissibility of electronic records.
Section 65B: Provides conditions under which electronic records are considered “secondary evidence”.
Key Principle:
For digital data to be admissible, it must be authentic, reliable, and maintained without tampering.
2. Conditions for Admissibility (Section 65B)
Under Section 65B(4) of IEA:
The electronic record must be produced from a computer or device regularly used to store or process information.
It must be maintained in the ordinary course of business.
There must be a certificate signed by a competent person (proprietor, manager, or someone in charge) stating:
The record was generated/produced by a computer.
The device was functioning properly.
The record has not been tampered with.
Without this certificate, digital evidence may be inadmissible (as clarified in multiple Supreme Court judgments).
