The Role of Forensic Evidence in Criminal Trials: Legal Reliability and Challenges

Abstract

This study discusses the utility and reliance of forensic evidence in contemporary criminal litigations, the legal dependability of forensics, ethical considerations, and the forensics evidence’s ever-growing relevance in the legal ecosystem. The studies trace the history of forensic science evolving from rudimentary forensics like toxicology and fingerprinting to contemporary forensics including artificial intelligence, DNA forensics, digital forensics and AI technology. The accuracy and objectivity of the judicial process is enhanced by forensic evidence, but its reliability is often undermined by inconsistent laboratory practices mistake, biases of experts, and differing jurisdictional standards of admissibility. The contrastive analysis emphasizes the developed countries such as the USA and UK, with them rigidly in place regulatory frameworks, verus the underdeveloped countries, for example, Pakistan, with their infrastructural and institutional dysfunctions. However, the ethical issues around the misuse of judicial evidence and the unequal distribution of forensic tools and resources, add even more complications to the situation. This article maintains that the scientific development and legal protections of forensic science and technology must be balanced to achieve effective governance. Also, more reliance must be placed on the ethical, legal, scientific, and interdisciplinary collaborations with artificial intelligence in the future along with strengthened quality control. To sum up, confidence of the public toward the criminal justice system will be restored by strengthening the reliability and accountability of forensics.
