Introduction
The Narcotic Drugs and Psychotropic Substances Act, 1985 shifts part of the burden of proof to the accused. Section 35 presumes a culpable mental state, and Section 54 presumes that a person in possession of a drug, without a satisfactory explanation, has committed an offence under the Act. Many of the NDPS judgments published on NyayVidhan turn on these two presumptions.
The presumptions are not a shortcut to conviction. The Supreme Court has held repeatedly that they arise only after the prosecution proves the foundational facts, above all possession, beyond reasonable doubt. This guide explains what the sections say, what "conscious possession" means, how the presumptions are rebutted, how they apply to owners of vehicles and premises, and why they cannot rescue a recovery that is itself unproved. It draws on Supreme Court and Rajasthan High Court judgments published on NyayVidhan, each cited with the Court's own paragraph numbers.
The Statutory Provisions
Both sections are set out in full by the Supreme Court in Manoj Tejraj Jain v. State of Gujarat (2025 INSC 1090, paras 35-36).
Section 35 provides that in any prosecution for an offence under the Act which requires a culpable mental state, the court shall presume the existence of that mental state, but it is a defence for the accused to prove that he had no such mental state with respect to the act charged. "Culpable mental state" includes intention, motive, knowledge of a fact, and belief in, or reason to believe, a fact. Sub-section (2) states that, for the purpose of the section, a fact is proved only when the court believes it to exist beyond a reasonable doubt, and not merely when its existence is established by a preponderance of probability.
Section 54 provides that in trials under the Act it may be presumed, unless and until the contrary is proved, that the accused has committed an offence in respect of any narcotic drug, psychotropic substance or controlled substance, any opium poppy, cannabis plant or coca plant growing on land he has cultivated, any apparatus or utensils for manufacture, or any materials or residue of manufacture, for the possession of which he fails to account satisfactorily.
Valid, but Only After the Foundational Facts Are Proved
In Noor Aga v. State of Punjab ((2008) 16 SCC 417), the Supreme Court upheld Sections 35 and 54 as constitutional, but held that their procedural requirements must be strictly complied with (paras 84, 170). The reverse burden arises only after the prosecution proves the foundational facts, including possession, beyond reasonable doubt; the accused then rebuts on a preponderance of probability (paras 88-89). Balwinder Singh (Binda) v. NCB (2023 INSC 852) restated the same two standards (paras 15-16).
Later decisions apply the rule at every stage:
- Registering a case does not shift the burden; it arises only after the prosecution establishes a prima facie case (Gorakh Nath Prasad v. State of Bihar, (2018) 2 SCC 305, para 6).
- The reverse burden under Sections 35 and 54 arises only after the prosecution proves its case beyond reasonable doubt (Vijay Pandey v. State of Uttar Pradesh, 2019 INSC 837, para 7).
- The presumptions need the foundational facts, including the actus reus, proved beyond reasonable doubt (Manoj Tejraj Jain, paras 54-60). In that case the Supreme Court found that the High Court had discussed no evidence of conspiracy, and three appellants were acquitted (paras 23-28, 70).
- Once possession and knowledge are proved, the court must draw the Section 35 presumption of a culpable mental state (Balwinder Singh, para 19).
What "Conscious Possession" Means
Control and knowledge. Possession under the Act must be conscious. In Ram Singh v. Central Bureau of Narcotics ((2011) 11 SCC 347), control over the goods and title were treated as the tests, and a hotel servant was held not to possess opium belonging to his masters unless it was left in his custody under his absolute control (para 15). Direct physical control together with knowledge establishes conscious possession, and once possession is shown the Section 54 presumption applies unless explained (Jeet Ram v. NCB, 2020 INSC 545, para 11).
Proximity is not enough. In State v. Hazari Lal (2026:RJ-JD:18230), the Rajasthan High Court held that possession requires both physical control and knowledge, that mere proximity to contraband does not establish it, and that a recovery from a house requires proof of the accused's dominion over the premises (paras 6, 8-9). Contraband found in a co-accused's room did not prove the appellants' possession without evidence that they brought it there (Bothilal v. Intelligence Officer, NCB, 2023 INSC 432, paras 17-18).
Conduct and control of the place. Conscious possession is decided on the facts. A woman found sitting on bags of poppy husk, who behaved suspiciously and admitted what they contained, was held to be in conscious possession (Balbir Kaur v. State of Punjab, 2009 INSC 876, paras 9-10). In Manoj Tejraj Jain, control of the godown and a bare denial justified the Section 54 presumption against its lessee (paras 43-51).
Occupants and drivers of vehicles. Once possession is established, the accused must show that it was not conscious, and the driver did not stand on a different footing from the other occupants (Madan Lal v. State of Himachal Pradesh, (2003) 7 SCC 465, paras 27-29). In Baldev Singh v. State of Haryana ((2015) 17 SCC 554), the driver was in all probability aware of the contents of the bags in the trolley, and once physical possession was proved the Section 35 burden shifted to him (para 12). At the bail stage, the absence of contraband on the accused's person does not dispense with scrutiny under Section 37 when it is concealed in the vehicle he travels in (Union of India v. Md. Nawaz Khan, 2021 INSC 526, para 25).
Nothing recovered. Where nothing was recovered from an accused drug user or her bag and the case rested on confessions, the Supreme Court found no complicity in conscious possession and quashed her prosecution (Sanjana Bhaskaran v. State of Telangana, Criminal Appeal No. 4877 of 2026, paras 3, 6, 7-8).
Rebutting the Presumptions
The accused need not always lead separate defence evidence. In Abdul Rashid Ibrahim Mansuri v. State of Gujarat (Criminal Appeal No. 78 of 1992, decided 2000), the Supreme Court held that the Section 35 presumption can be rebutted from circumstances in the prosecution's own evidence (paras 20-22). The Supreme Court has said the same of the reverse burden under the Negotiable Instruments Act: an accused need not examine himself and may rely on the materials already on record (Krishna Janardhan Bhat v. Dattatraya G. Hegde, 2008 (1) SCALE 421, para 23).
The right to rebut must be real. In CBI v. Dayamoy Mahato (2025 INSC 1418), a case under another reverse-burden law, the Supreme Court said courts must ensure undertrials can meaningfully rebut the presumption, including through legal aid, and directed High Courts to audit pending reverse-burden cases (paras 18-19, 24).
Owners of Vehicles and Premises: Section 25
Section 25 punishes an owner who knowingly permits his vehicle or premises to be used for an offence. The Supreme Court has held that this knowledge is itself a foundational fact the prosecution must prove before Section 35 can operate:
- In Bhola Singh v. State of Punjab ((2011) 11 SCC 653), Section 25 needed evidence that the owner knowingly permitted the vehicle's use; following Noor Aga, the presumption arises only after that is proved, and a wrong residential address given when registering the truck did not fasten the co-owner with knowledge (paras 9-10).
- In Harbhajan Singh v. State of Haryana (2023 INSC 424), the presumption was unavailable until the foundational facts were proved, and a conviction resting merely on registered ownership, with the burden of defence placed on the owner, was legally unsustainable (paras 7, 11-12).
- In Aniket v. State of Rajasthan (2026:RJ-JP:29657), the Rajasthan High Court applied this at the stage of charge: the prosecution must show, at least prima facie, the owner's knowledge, consent or complicity; Section 35 cannot operate in a vacuum; and a charge-sheet based only on registration was unsustainable. The petitioner was discharged (paras 9, 11, 13-14, 17).
The Presumptions Cannot Rescue an Unproved Recovery
Because the presumptions rest on proved possession, any defect in proving the recovery reaches them too.
- Search of the person. A Section 54 presumption can be raised only after possession is established in a search that complies with Section 50 (State of Punjab v. Baldev Singh, Constitution Bench, 1999, para 93). Compliance with Section 50 cannot be presumed as an official act under Section 114, illustration (e) of the Evidence Act (Saiyad Mohd. Saiyad Umar Saiyed v. State of Gujarat, (1995) 3 SCC 610, paras 9-10). A Section 50 breach in the personal search does not, however, taint contraband independently recovered from a vehicle (State of Punjab v. Baljinder Singh, 2019 INSC 1145, paras 14, 16-17).
- Producing the contraband. Without the seized material produced as an exhibit, a forensic report proves neither the seizure nor the nature of the substance, and unexplained non-production is fatal (Gorakh Nath Prasad, paras 7-8). Non-production of the bulk and samples also warrants an adverse inference under Section 114(g) of the Evidence Act (Noor Aga, paras 142-143).
- Linking the sample. The sample tested must be shown to be the sample seized; failing to link them is no different from failing to produce the contraband (Vijay Pandey, para 8).
- Statements are not proof of possession. After Tofan Singh, a conviction resting only on Section 67 statements cannot stand, but independently proved possession still attracts Section 35 (Balwinder Singh, paras 12, 19). See our guide to Section 67 statements and Tofan Singh.
Appeals Against Acquittal
The stringency of the Act cuts both ways. The greater the punishment, the stricter the degree of proof required (Hazari Lal, para 5). In State of Rajasthan v. Suraj Dass (2026:RJ-JD:17456), the Rajasthan High Court held that where two views are reasonably possible the one favouring the accused must be adopted, and that the prosecution must prove its case with the certainty the Act requires (paras 6.1-6.2).
The Same Structure in Other Statutes
Reverse burdens appear in other laws, and the Supreme Court has read them the same way. A reverse burden does not by itself make a law unconstitutional, because the presumption is rebuttable and follows proof of foundational facts (Seema Silk & Sarees v. Directorate of Enforcement, 2008 (7) SCALE 624, paras 16-17). Under the Prevention of Corruption Act, the Section 20 presumption arises only after acceptance, and therefore demand, is proved (P. Satyanarayana Murthy v. District Inspector of Police, Criminal Appeal No. 31 of 2009, decided 2015, para 20). Under a State cattle-preservation law, the reverse burden arose only after the essential ingredients of the offence were proved (Saurabh Bajaj v. State of Chhattisgarh, 2026 INSC 1076, para 8).
Key Points
- Sections 35 and 54 are valid, but they arise only after the prosecution proves the foundational facts, including possession, beyond reasonable doubt (Noor Aga, paras 84, 88-89).
- Possession must be conscious: physical control with knowledge. Mere proximity, or contraband in someone else's room, is not enough (Hazari Lal, paras 6, 8-9; Bothilal, paras 17-18).
- Once possession is proved, the burden shifts to the accused, who may rely on circumstances in the prosecution's own evidence (Baldev Singh v. State of Haryana, para 12; Abdul Rashid Ibrahim Mansuri, paras 20-22).
- A vehicle owner's knowledge is a foundational fact; registration alone supports neither a conviction nor a charge (Harbhajan Singh, paras 7, 11-12; Aniket, paras 9, 11).
- No presumption can cure an unproved recovery: a Section 50 breach on a personal search, unproduced contraband or an unlinked sample defeats it (Baldev Singh 1999, para 93; Gorakh Nath Prasad, paras 7-8; Vijay Pandey, para 8).
