Forensic science has become an important part of criminal investigation in recent years. Courts and investigating agencies increasingly rely on scientific evidence such as DNA analysis, fingerprints, toxicology reports, and digital evidence to establish facts and determine responsibility. The growing use of scientific methods has improved the quality of criminal investigations and reduced excessive dependence on confessions and witness testimony alone. At the same time, the success of scientific investigation depends on the availability of strong forensic institutions capable of examining evidence quickly and accurately. Although India has expanded its forensic facilities over the years, several practical difficulties continue to affect the system. Many forensic laboratories are required to handle a large number of cases with limited resources. Delays in examinations, shortage of trained experts, uneven distribution of forensic facilities, and inadequate technological support often slow down the process of investigation. As a result, forensic reports are not always available within a reasonable time, creating difficulties for investigating officers, prosecutors, courts, victims, and accused people. This article examines how weaknesses in forensic infrastructure contribute to delays in criminal trials in India. It studies the existing forensic framework, identifies the major institutional and infrastructural shortcomings affecting forensic services, and analyses the impact of these deficiencies on the criminal justice process. The article argues that delays in criminal trials cannot be viewed only as a judicial problem because they are also linked to the capacity of forensic institutions that support investigations. It further highlights the need for policy measures aimed at strengthening laboratory facilities, increasing professional capacity, improving coordination among institutions, and reducing delays in forensic examination. Strengthening forensic infrastructure is essential not only for effective investigation but also for ensuring timely justice and maintaining public confidence in the criminal justice system.
