The newly introduced Indian criminal law also intends to imperatively incorporate the use of forensic science in the criminal investigation system to aid and assist the investigating officers in evidence collection, thus allowing them to present a strong case against the accused. Though the use of forensic science would ease and fasten the investigation process but considering the limited evidentiary value of forensic evidence in the criminal justice system today, the proposed law might not be able to help the legislature achieve its ultimate objective of increasing the conviction rate. This paper aims to navigate through various cases and judgements and showcase the status that forensic evidence holds in the present criminal justice system to understand the relationship shared between forensic evidence and conviction rate as well as highlight the potential modifications that can be introduced to increase the admissibility value of expert witness testimony in the court of law.
