Key Judicial Principles
Authentication is critical: Courts require proof that posts or messages are created or sent by the defendant.
Chain of custody and metadata: Digital evidence must be preserved and verified to ensure admissibility.
Direct and corroborative evidence: Social media can serve both as direct evidence (confessions, images) and supporting evidence (planning, coordination).
Encryption and privacy: Even encrypted messages can be admitted if obtained lawfully and verified.
Probative value vs prejudicial effect: Courts balance the evidentiary value against the potential for unfair prejudice.
Social media evidence has now become central to criminal investigations, and courts increasingly rely on forensic verification, metadata analysis, and digital authentication to admit posts, messages, images, and videos.
