Supreme Court Guidelines On Management Of DNA Evidence

Supreme Court in KATTAVELLAI @ DEVAKAR VERSUS STATE OF TAMIL NADU [2025 LiveLaw (SC) 703] issued the following Guidelines for the management of DNA Evidence1. The collection of DNA samples once made after due care and compliance of all necessary procedure including swift and appropriate packaging including a) FIR number and date; b) Section and the statute involved therein; c) details of I.O., Police station; and d) requisite serial number shall be duly documented. The document recording the collection shall have the signatures and designations of the medical professional present, the investigating officer and independent witnesses. Here only we may clarify that the absence of independent witnesses shall not be taken to be compromising to the collection of such evidence, but the efforts made to join such witnesses and the eventual inability to do so shall be duly put down in record.2. The Investigating Officer shall be responsible for the transportation of the DNA evidence to the concerned police station or the hospital concerned, as the case may be. He shall also be responsible for ensuring that the samples so taken reach the concerned forensic science laboratory with dispatch and in any case not later than 48- hours from the time of collection. Should any extraneous circumstance present itself and the 48-hours timeline cannot be complied with, the reason for the delay shall be duly recorded in the case diary. Throughout, the requisite efforts be made to preserve the samples as per the requirement corresponding to the nature of the sample taken.3. In the time that the DNA samples are stored pending trial appeal etc., no package shall be opened, altered or resealed without express authorisation of the Trial Court acting upon a statement of a duly qualified and experienced medical professional to the effect that the same shall not have a negative impact on the sanctity of the evidence and with the Court being assured that such a step is necessary for proper and just outcome of the Investigation/Trial.4. Right from the point of collection to the logical end, i.e., conviction or acquittal of the accused, a Chain of Custody Register shall be maintained wherein each and every movement of the evidence shall be recorded with counter sign at each end thereof stating also the reason therefor. This Chain of Custody Register shall necessarily be appended as part of the Trial Court record. Failure to maintain the same shall render the I.O. responsible for explaining such lapse. The Directors General of Police of all the States shall prepare sample forms of the Chain of Custody Register and all other documentation directed above and ensure its dispatch to all districts with necessary instruction as may be required."The Court directed the Registry to send a copy of this judgment to all High Courts and also the Directors General of the Police of all States to ensure necessary compliance.Further, the Court also urged the Police Academies of the States to examine the necessity of conducting training of the Investigating Officers to ensure full compliance with the requisite precautions and procedures in accordance with the directions issued herein above.
