The Supreme Court of India upheld the conviction of four appellants for offenses under the Narcotic Drugs and Psychotropic Substances Act related to the seizure of 66.1 kg of heroin. The Court found that the confessional statements made by the appellants to officers of the Directorate of Revenue Intelligence were voluntary and admissible. It also held that the recovery of evidence could not be doubted due to corroboration of the confessional statements and the search/seizure conducted by a gazetted officer at the customs office rather than the site of apprehension did not establish prejudice against the accused.
