Yes — and electronic evidence is one of the most technically challengeable categories of prosecution evidence precisely because strict legal conditions must be met before it can be admitted, and those conditions are regularly not fully met in Patna's criminal proceedings. As cases increasingly rely on CCTV footage, call detail records, WhatsApp messages, banking transaction logs, and screen recordings, knowing how to attack such evidence has become essential to criminal defence in Patna.

The governing framework is the Bharatiya Sakshya Adhiniyam 2023, particularly Sections 61 to 63 BSA. Section 63 BSA (the successor to the old Section 65B of the Evidence Act) imposes a mandatory certificate requirement as a condition precedent to the admissibility of electronic records as secondary evidence. Without the proper certificate from the responsible official of the computer system that generated or stored the record, the electronic evidence is generally inadmissible — the Supreme Court confirmed this unequivocally in Anvar P.V. v. P.K. Basheer and Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal, and these rulings apply in Patna's courts. The prosecution's first line of obligation is to produce a compliant certificate, and your counsel's first line of challenge is to verify whether the certificate is present, correctly executed, and actually covers the specific record being tendered.

Beyond the certificate, there are substantive grounds to attack electronic evidence on its integrity. Your counsel can challenge the chain of custody from seizure to court — any break in the documented chain raises the possibility of tampering or substitution. You can challenge authenticity through metadata, timestamps, and hash values — asking whether the file in court is genuinely the original and unaltered. In CCTV cases, you can challenge clock synchronisation (whether the system time matched actual time), camera angle and field of view (whether the footage actually shows what the prosecution claims), and video quality sufficient to establish identity. The criminal defence advocates at the Patna panel of Aapka Legal Advice experienced in digital evidence cases can analyse the prosecution's electronic material specifically for these vulnerabilities and build the challenge systematically.
