Operating at national, state, and regional levels, they support law enforcement agencies and courts by establishing facts, identifying offenders, and delivering expert opinions. They are, therefore, indispensable pillars in the pursuit of justice.<\/p><div id=\"ez-toc-container\" class=\"ez-toc-v2_0_89 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #0c0c0c;color:#0c0c0c\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #0c0c0c;color:#0c0c0c\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.legalserviceindia.com\/Legal-Articles\/forensic-laboratories-the-role-and-functions-of-central-and-state-institutions\/#1_Introduction\" >1.

Central Bureau of Narcotics (2013)<\/em>, the Supreme Court emphasized the urgent need to expand forensic infrastructure, strengthen Central and State Forensic Science Laboratories, and modernize investigative capabilities.<\/p>\n\n\n\n<h2 id=\"h-7-comparative-perspective-forensic-laboratory-systems-in-india-and-the-united-states\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"7_Comparative_Perspective_Forensic_Laboratory_Systems_in_India_and_the_United_States\"><\/span>7. Comparative Perspective: Forensic Laboratory Systems in India and the United States<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Forensic laboratory systems vary significantly across jurisdictions, but their core purpose remains the same: to provide scientific support for criminal investigations and judicial proceedings.<\/p>\n\n\n\n<h3 id=\"h-7-1-forensic-laboratory-system-in-india\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"71_Forensic_Laboratory_System_in_India\"><\/span>7.1. Forensic Laboratory System in India<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In India, forensic services operate through a structured and centralized framework consisting of Central Forensic Science Laboratories (CFSLs), State Forensic Science Laboratories (SFSLs), Regional Forensic Science Laboratories, and specialized divisions under the Directorate of Forensic Science Services (DFSS).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These laboratories support police agencies, courts, and investigative bodies by conducting examinations in biology, chemistry, ballistics, toxicology, cyber forensics, questioned documents, and DNA analysis.<\/p>\n\n\n\n<h3 id=\"h-7-2-forensic-laboratory-system-in-the-united-states\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"72_Forensic_Laboratory_System_in_the_United_States\"><\/span>7.2. Forensic Laboratory System in the United States<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In contrast, the United States follows a decentralized forensic model. Forensic laboratories may function under municipal police departments, county agencies, state bureaus of investigation, medical examiner offices, or federal agencies such as the Federal Bureau of Investigation (FBI), Drug Enforcement Administration (DEA), and Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF).<\/p>\n\n\n\n<h3 id=\"h-7-3-accreditation-and-quality-assurance\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"73_Accreditation_and_Quality_Assurance\"><\/span>7.3. Accreditation and Quality Assurance<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">One important difference lies in accreditation and quality assurance. In the United States, many forensic laboratories seek accreditation through the ANSI National Accreditation Board (ANAB), ensuring compliance with internationally accepted forensic standards such as ISO\/IEC 17025. In India, accreditation and quality control are increasingly emphasized as forensic demands continue to expand.<\/p>\n\n\n\n<h3 id=\"h-7-4-courtroom-admissibility-of-forensic-evidence\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"74_Courtroom_Admissibility_of_Forensic_Evidence\"><\/span>7.4. Courtroom Admissibility of Forensic Evidence<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Another major distinction involves courtroom admissibility.
