(a) any narcotic drug or psychotropic substance or controlled substance;

(c) any apparatus specially designed or any group of utensils specially adapted for the manufacture of any narcotic drug or psychotropic substance; or

Legal Commentary & Landmark Judgments: Section 54
Section 54 of the NDPS Act enacts a reverse burden statutory presumption, providing that in trials under the Act, it may be presumed that the accused has committed an offence if they fail to account satisfactorily for the possession of any illicit narcotic drug or psychotropic substance.
To defeat the Section 54 presumption, do not rely on a bare denial; establish through cross-examination of panch witnesses that the vehicle or room was accessible to multiple third parties, negating exclusive conscious possession.
