Forensic Psychology and Criminal Jurisprudence: An Analysis as to the Admissibility of Expert Evidence in Adversarial System

Abstract

Forensic psychology is recognized in India as a branch of applied psychology that is used in crime investigation, victim assistance, and victim rehabilitation. Forensics plays a critical role in remodelling the rule of law by providing scientific evidence to support legal investigations, and proceedings. This evidence can be used to support a prosecution or defence in criminal cases, and can help to ensure that justice is served. Forensic evidence can also be used to exonerate individuals who have been wrongfully accused or convicted of crimes. Overall, forensic science has developed into a vital tool in the administration of justice, and its application has served to increase the fairness and certainty of courtroom procedures. The background of any illegal behaviour and activities of a mentally impaired person can be understood with the help of forensic psychiatrists, paving the way for the establishment of stronger evidence or undermining the probative value of already available evidence. This article provides an overview of forensic psychiatry in the Indian judiciary, highlighting the key areas where this discipline has a significant impact and to make a critical analysis of the efficiency of the existing machinery in evaluating the psychological expert’s evidence and the suitable remedies for the effective working of the system in this field.
