Fingerprint And Forensic Evidence In Indian Courts
Fingerprint and Forensic Evidence in Indian Courts
Fingerprints are one of the oldest and most reliable forms of forensic evidence used in criminal investigations worldwide, including India. They serve as a unique identifier of individuals because no two persons have identical fingerprints. Forensic evidence, which includes fingerprints, DNA, ballistic reports, handwriting analysis, and more, plays a vital role in the criminal justice system to establish facts, prove guilt, or establish innocence.
In India, forensic evidence is admissible under the Indian Evidence Act, 1872, especially sections related to expert opinion (Section 45) and relevant facts (Section 9). Fingerprint evidence, being scientific and objective, has been frequently relied upon by courts in convictions and acquittals.
