The Medico-Legal system plays a pivotal role in the criminal justice system by providing crucial forensic evidence that aids in the investigation and adjudication of criminal cases. This paper presents a critical examination of the importance of the Medico-Legal system in the context of forensic evidence and its impact on criminal cases. Forensic evidence derived from the Medico-Legal system encompasses a wide array of disciplines, including forensic pathology, toxicology, DNA analysis, and forensic psychiatry. These disciplines contribute to the collection, analysis, and interpretation of evidence essential for establishing facts, determining cause of death, identifying perpetrators, and ensuring justice in criminal proceedings. Through a comprehensive review of literature and case studies, this paper delves into the various aspects of the Medico-Legal system and its significance in criminal investigations. It explores how forensic evidence obtained through autopsy examinations, crime scene analysis, and expert testimony serves as a cornerstone in establishing guilt or innocence and influencing legal outcomes.
