Evidentiary Presumptions In Narcotics Cases Under Nepalese Law
⚖️ Evidentiary Presumptions in Narcotics Cases Under Nepalese Law
1. Introduction
Evidentiary presumptions in narcotics cases are legal provisions that shift the burden of proof in certain situations, making it easier for the prosecution to secure a conviction in drug-related offenses.
Nepal has adopted such presumptions to combat the serious social and criminal harm caused by narcotics trafficking and consumption.
2. Legal Framework
1. Narcotic Drugs (Control) Act, 2033 (1976)
Governs production, sale, trafficking, and possession of narcotics in Nepal.
Sections of relevance:
Section 6: Possession of narcotics establishes a rebuttable presumption of intent to sell or distribute if quantity exceeds threshold.
Section 8: Possession of paraphernalia or certain substances triggers presumption of use or trafficking.
Section 13: Failure to account for narcotics or provide a lawful explanation can lead to criminal liability.
2. Muluki Criminal Code, 2017
Section 35–40 on drug offenses incorporates evidentiary presumptions, particularly for trafficking, smuggling, and repeated possession.
Allows courts to presume knowledge and intent once the accused is found in possession of narcotics beyond personal use limits.
3. Rationale
Narcotics crimes are often clandestine, making it difficult for the prosecution to prove intent directly.
Presumptions help facilitate convictions in cases of large-scale trafficking while remaining rebuttable if the accused provides credible explanations.
3. Key Evidentiary Presumptions
Possession Implies Knowledge
If a person is found with a controlled substance, courts presume they knew of the presence and nature of the substance.
Possession Beyond Certain Quantities Implies Trafficking
Small amounts: Personal consumption.
Large amounts: Presumed intent to sell or distribute.
Paraphernalia Presumption
Possession of tools (scales, packaging materials) linked to trafficking triggers presumption of commercial intent.
Failure to Provide Explanation
If accused cannot provide a credible explanation for possession, the court may presume criminal intent.
Transport or Border Crossing
Narcotics found during transit may invoke presumption of smuggling, shifting the burden to the accused to prove otherwise.
4. Case Law Illustrations
