The statute is unusual for its statutory presumptions in section 37, which can shift the burden onto the accused once the prosecution establishes possession of certain quantities. This page explains how trafficking charges are defended in Malaysian courts, including the Johor Bahru High Court where the firm regularly appears.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The structure of section 39B<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Section 39B(1) DDA 1952 makes it an offence to traffic in dangerous drugs. The statutory definition of &#8220;trafficking&#8221; in section 2 is broad \u2014 it includes manufacturing, importing, exporting, transporting, supplying or otherwise dealing with any dangerous drug. The penalty under s.39B(2) is the death sentence; following the Abolition of Mandatory Death Penalty Act 2023, the courts now have discretion to impose either death or life imprisonment with whipping.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Statutory presumptions \u2014 section 37<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The presumptions in section 37 are the prosecution&#8217;s most powerful tool. Once the prosecution proves possession of certain quantities, the accused is presumed to be trafficking. The threshold quantities (s.37(da)) include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Heroin \/ morphine \u2014 15 grams or more<\/li>\n\n\n\n<li>Cannabis \u2014 200 grams or more<\/li>\n\n\n\n<li>Cocaine \u2014 40 grams or more<\/li>\n\n\n\n<li>Methamphetamine \u2014 50 grams or more<\/li>\n\n\n\n<li>Methylenedioxymethamphetamine (MDMA \/ ecstasy) \u2014 30 grams or more<\/li>\n\n\n\n<li>Ketamine \u2014 100 grams or more<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The Federal Court in <em>Alma Nudo Atenza v PP<\/em> [2019] 4 CLJ 567 held that the section 37(da) presumption operates on a balance of probabilities (rebuttable), but the constitutional challenge to the double presumption (s.37(d) plus s.37(da) operating together) was successful. After Alma Nudo, the prosecution must independently prove either possession or trafficking \u2014 it cannot use both presumptions to shift the burden cumulatively.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Common defence strategies<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Possession not proved<\/strong> \u2014 challenging mens rea and control of the drugs (whether the accused knew of the drug&#8217;s existence and exercised possession)<\/li>\n\n\n\n<li><strong>Innocent carrier<\/strong> \u2014 the accused was unaware that a parcel\/bag\/vehicle contained drugs<\/li>\n\n\n\n<li><strong>Chain of custody<\/strong> \u2014 attacking the integrity of the seized exhibit between arrest and analyst examination<\/li>\n\n\n\n<li><strong>Analyst report defects<\/strong> \u2014 challenging the chemist&#8217;s testing methodology, calibration, weight measurements<\/li>\n\n\n\n<li><strong>Confessions inadmissibility<\/strong> \u2014 cautioned statements obtained without compliance with section 113 CPC<\/li>\n\n\n\n<li><strong>Identification disputes<\/strong> \u2014 visual identification by police officers in raids<\/li>\n\n\n\n<li><strong>Quantum dispute<\/strong> \u2014 net weight after deducting impurities; relevant where on the borderline of s.37(da) thresholds<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Sentencing after the 2023 abolition of mandatory death penalty<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The Abolition of Mandatory Death Penalty Act 2023 gives the trial court discretion in trafficking and other previously-mandatory-death offences. Mitigation factors now relevant include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Age and antecedents of the accused<\/li>\n\n\n\n<li>Role in the trafficking chain (mule vs principal)<\/li>\n\n\n\n<li>Cooperation with authorities (s.40 DDA reduction)<\/li>\n\n\n\n<li>Personal circumstances \u2014 dependants, mental health, addiction<\/li>\n\n\n\n<li>Time spent on remand<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Cooperation under section 40<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Section 40 DDA 1952 allows the Public Prosecutor to issue a certificate of cooperation, which can result in significant sentence reduction. The decision is at the prosecutor&#8217;s discretion; defence counsel typically negotiate this in parallel with trial preparation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Possession (s.6, s.12) versus trafficking (s.39B)<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Section 6<\/strong> \u2014 possession (penalty: 5 years to life imprisonment + whipping)<\/li>\n\n\n\n<li><strong>Section 12(2)<\/strong> \u2014 possession with intent to traffic (penalty: 5 years to life + 10 strokes)<\/li>\n\n\n\n<li><strong>Section 39A(1)<\/strong> \u2014 enhanced possession (above s.37(da) quantities, but below trafficking) \u2014 minimum 5 years + whipping<\/li>\n\n\n\n<li><strong>Section 39A(2)<\/strong> \u2014 enhanced possession of larger quantities \u2014 minimum 5 years + whipping<\/li>\n\n\n\n<li><strong>Section 39B<\/strong> \u2014 trafficking \u2014 death or life with whipping<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Reducing a trafficking charge under section 39B to enhanced possession under section 39A(2), or further to simple possession under section 6, is often the most realistic defence outcome. This requires careful pleading-stage representations to the Public Prosecutor, supported by the evidence.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Is the death penalty still mandatory for drug trafficking in Malaysia?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. The Abolition of Mandatory Death Penalty Act 2023 made the death sentence discretionary for s.39B drug trafficking. The trial court can now impose either death or life imprisonment with whipping.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">If I was just carrying a bag for someone else, can I still be convicted of trafficking?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Possibly, depending on whether you knew there were drugs and the quantity exceeds the s.37(da) thresholds. The defence of innocent carrier requires you to have had no knowledge or reason to know of the drugs. This is fact-specific and requires detailed examination of the circumstances.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is the difference between possession and trafficking?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Possession is having control over the drug. Trafficking is dealing with it (transporting, supplying, etc.). The key trigger is quantity: above the s.37(da) thresholds, possession alone creates a presumption of trafficking that the accused must rebut.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I get bail on a drug trafficking charge?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Section 39B is unbailable. Bail is therefore extremely rare and only granted in exceptional circumstances such as serious medical conditions or where the prosecution case appears very weak.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How long does a drug trafficking trial take?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Typically 18\u201336 months in the High Court, depending on the complexity of evidence (number of accused, chemist disputes, eyewitness identification, video evidence). Appeals add another 1\u20133 years.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>See also:<\/strong> <a href=\"https:\/\/hbchee.com\/wp\/criminal-defence-malaysia\/\">Criminal Defence Lawyer in Malaysia<\/a> | <a href=\"https:\/\/hbchee.com\/wp\/criminal-lawyer-johor-bahru\/\">Criminal Lawyer in Johor Bahru<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Contact<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Telephone: +60 17-702 2800<br>Email: hbchee.cp@gmail.com<br>Office: No 1-10 (1st Floor), Jalan Maju 1, Taman Maju, 83000 Batu Pahat, Johor.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Drug Trafficking Defence in Malaysia \u2014 Dangerous Drugs Act 1952 Section 39B Dangerous Drugs Act 1952 \u00b7 Statutory presumptions s.37 \u00b7 Mandatory death\/lifeFederal Court guidance: Alma Nudo Atenza, Ong Ah Chuan, PP v Yong Vui Kong Drug trafficking under the Dangerous Drugs Act 1952 (&#8220;DDA 1952&#8221;) is the most serious drug offence in Malaysian law, [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_yoast_wpseo_focuskw":"","_yoast_wpseo_title":"","_yoast_wpseo_metadesc":"","_glsr_average":0,"_glsr_ranking":0,"_glsr_reviews":0,"footnotes":""},"class_list":["post-1953","page","type-page","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Drug Trafficking Defence under the Dangerous Drugs Act 1952 - Chris &amp;
