E-Discovery In Criminal Investigations
I. What is E-Discovery?
E-Discovery (Electronic Discovery) refers to the process of identifying, collecting, preserving, reviewing, and producing electronically stored information (ESI) during criminal investigations or litigation. ESI includes emails, text messages, social media posts, documents, databases, videos, audio recordings, and metadata.
In criminal cases, e-discovery is crucial for uncovering digital evidence that may prove guilt or innocence.
II. Importance of E-Discovery in Criminal Investigations
Digital evidence often holds key clues in cybercrime, fraud, drug trafficking, terrorism, and white-collar crimes.
ESI can establish timelines, prove or disprove alibis, reveal communications, and uncover conspiracies.
E-discovery helps meet the prosecution’s burden of proof and defense rights to fair trial.
Requires careful handling due to privacy concerns, data volume, and technical complexity.
III. Legal Framework for E-Discovery
India:
Information Technology Act, 2000 (Sections 65-74 regarding electronic evidence)
Indian Evidence Act, 1872 (Sections 65A and 65B) — admissibility of electronic records.
United States:
Federal Rules of Criminal Procedure (Rule 16 - Discovery)
Federal Rules of Evidence (Rule 902(13) - self-authentication of certified electronic evidence)
International: Varies, but most jurisdictions recognize electronic evidence subject to authenticity and chain-of-custody rules.
IV. Challenges in E-Discovery
Volume & Complexity: Large datasets require forensic tools for searching relevant info.
Data Integrity & Preservation: Need to prevent tampering or deletion.
Privacy & Legal Compliance: Respecting confidentiality and rights.
Cross-border Jurisdiction Issues: Data may be stored internationally.
Authentication & Admissibility: Courts require proof that evidence is genuine.
V. Case Law Analysis

Significance:
Set important limits on scope and retention in e-discovery.
6. People v. Diaz (California, 2011)
Facts:
Police searched defendant’s cellphone voicemail without a warrant.
