EduLaw Legal Intelligence Updated: 8 August 2026 Practical litigation guide Approx. 2,956 words IMPORTANT LEGAL CORRECTION The BSA provision is Section 63, not Section 65B. The cover uses the familiar expression “Section 65B BSA”, but Section 65B belonged to the Indian Evidence Act, 1872. Under the Bharatiya Sakshya Adhiniyam, 2023, the corresponding statutory route for admissibility of computer outputs is principally Section 63 , read with Sections 61 and 62. The BSA came into force on 1 July 2024. For proceedings saved by the repeal-and-savings clause, the old Evidence Act may still govern. This article therefore uses the legally correct formulation: Section 63 BSA / legacy Section 65B jurisprudence . Electronic evidence is no longer a side issue in litigation. It is often the centre of the case. WhatsApp chats, emails, CCTV footage, call detail records, GPS data, online transactions, social-media posts, digital photographs, voice recordings, cloud files and device extractions can decide whether a fact is proved or remains only an allegation. Yet electronic evidence is frequently mishandled. One side files a screenshot and assumes the job is over. The other side shouts “tampering” without identifying any legal defect. Senior advocates approach the problem differently. They ask a sequence of disciplined questions: What exactly is the electronic record? Where did it originate? Who had lawful control over the system? How was it preserved? What form is being produced in court? Is the statutory certificate complete? Can authorship be proved? Is the record intact and contextual? And what, precisely, does the record prove? That sequence is the difference between merely producing a digital file and actually proving it. 01. Begin with the law: Sections 61, 62 and 63 BSA Section 61 of the Bharatiya Sakshya Adhiniyam recognises that an electronic or digital record is not to be denied admissibility merely because it exists in electronic form. Section 62 directs that the contents of electronic records may be proved in accordance with Section 63. Section 63 contains the special rules governing a “computer output” such as information printed, stored, recorded or copied from a computer, communication device or other electronic system. The practical message is simple: electronic evidence has documentary status, but the manner of proving it remains important. A printout, copied file, exported chat, CD, pen-drive copy, CCTV export or downloaded report cannot be treated casually merely because everyone can see what it contains. Section 63 requires the proponent to connect the output to a regularly used computer or communication system, show that information of that kind was fed into the system in the ordinary course, address proper operation of the system, and establish that the output reproduces or is derived from information regularly fed into it. Sub-section (4) also requires a certificate when the statement is sought to be given in evidence through this statutory route. SENIOR ADVOCACY RULE Do not begin with “Is this screenshot admissible?” Begin with “What is the source record, what is the form being tendered, and which statutory route proves it?” 02. The first distinction: admissibility is not authenticity This is the most important conceptual separation. A record can satisfy the statutory mode of proof and still be disputed on authenticity. Conversely, a record can look completely genuine yet fail because the required legal foundation was not laid. Admissibility asks whether the evidence can enter the record through the legally prescribed route. Authenticity asks whether the record is really what the party claims it is. Attribution asks who created, sent, recorded or controlled it. Integrity asks whether the record remained materially unchanged. Weight asks how much the court should ultimately rely on it. Take a WhatsApp screenshot. A certificate may explain how the screenshot or export was produced from a phone. That does not automatically prove that the opposing party authored the message. A saved contact name can be entered by anyone holding the phone. A profile picture can change. A device may be shared. A linked desktop session may exist. The advocate relying on the message must therefore prove more than the appearance of the screen. Senior advocates never allow these questions to collapse into a single phrase like “electronic evidence is proved.” They identify each layer and satisfy it separately. 03. What the Section 63 certificate should actually do A weak certificate is often a one-page ritual. A strong certificate performs an evidentiary function. It identifies the record, explains how it was produced, provides appropriate particulars of the device or system involved, and deals with the statutory con
