Crime has always seen a significant growth over successive years in India. The increase in number of crimes is always directly proportional the pendency of cases. The crimes and criminals in the modern era differ those from conventional times and therefore the physical evidence left on the crime scene is nil or negligible thus Investigating agencies always face difficulties to gather evidences, which connects them to the perpetrator. Further, the investigating agencies may list down possible suspects in a case; however, their involvement in the case has to be proved in the court by the prosecution. FPIT’s (Forensic Psychological Investigative Technique’s) such as Polygraph, BEOS (Brain Electrical Oscillation Signature Profiling), and Narco- Analysis which are byproducts of amalgamation of psychophysiological principles and technology have seen significant dependency upon them as a scientific aid in investigation and corroboration. These instruments individually and collectively have been used in various cases for varying purposes such as screening of suspects, determining the deception within the suspects and perpetrators as well as showing suspects experiential knowledge of participation in a crime. However, credibility of these FPIT’s have been questioned several times, when, there have been several reports claiming that individuals have been convicted or granted bail based on these tests. As established in the case of Selvi & others vs State Of Karnataka on 5 May, 2010 the evidentiary value of these tests is only corroborative. The question therefore arises weather individuals have really been convicted or granted bail based on these tests and what was the basis for the same. Hence, this study aims to examine the interpretation of results of these FPIT’s by the honorable courts in India and their evidentiary value by a case study of five judgments.
