Supreme Court made it mandatory for the investigating agency to seek viscera test in death due to poisoning on 21 January 2014.
A bench of Justices Ranjana P Desai and J Chelameswar ruled that in all the cases where poisoning is suspected, immediately after the post-mortem, the viscera should be sent to the forensic science laboratories (FSL).
The prosecuting agencies should ensure that the viscera is, in fact, sent to the FSL for examination and the FSL should ensure that the viscera is examined immediately and report is sent to the investigating agencies/courts post haste.
The court took serious note of a number of cases relating to death by poisoning which resulted in acquittal mainly because police failed to seek a viscera examination from forensic science laboratories (FSL).
About Viscera test
In the Viscera test the internal organs of the body, specifically those within the chest (as the heart or lungs) or abdomen (as the liver, pancreas or intestines) are tested thoroughly.
The Forensic Science Laboratories provide scientific assistance in crime investigation by way of examination of blood, semen, stains thereof and other.
