Summary
In Public Prosecutor v Sritharan K Raja Rajan ([2020] SGHC 121), the High Court convicted the accused of importing not less than 21.16g of diamorphine into Singapore under s 7 of the Misuse of Drugs Act (Cap 185, 2008 Rev Ed) (“MDA”). The case turned on the operation of the MDA presumptions: once the prosecution proved that the drugs were found in the accused’s possession and that he had brought them into Singapore, the law presumed both possession and knowledge. The accused accepted the applicability of these presumptions but sought to rebut the presumption of knowledge under s 18(2) by claiming he was unaware of the nature and quantity of the drugs he was carrying.
The court held that the accused failed to rebut the presumptions. It found his account—particularly his explanation that a person named “Fei Poh” was his supplier and that he believed he was transporting about 25g of methamphetamine—was not credible. The court emphasised inconsistencies between his recorded statements and his later testimony, as well as the improbability of his explanations in light of the surrounding circumstances and his conduct.
On sentence, the court found that the accused was a “courier” within the meaning of s 33B(2)(a) of the MDA and that the Public Prosecutor had issued a certificate of substantive assistance under s 33B(2)(b). This made the alternative sentencing regime under s 33B available. The court therefore exercised its discretion to impose life imprisonment (backdated to the date of arrest) and caning of 15 strokes.
What Were the Facts of This Case?
The accused, Sritharan K Raja Rajan, entered Singapore on 25 October 2017 at about 6.32am via Woodlands Checkpoint on a motorcycle bearing registration number JPH8350. The motorcycle was registered in his wife’s name. An Immigration and Checkpoints Authority (“ICA”) officer, Staff Sergeant Zainul Arifin bin Abdul Hamed, stopped the accused at the checkpoint.
After the stop, the accused was escorted to a nearby motorcycle parking area. At about 7.05am, Staff Sergeant Hamdan Shah bin Abu Baker (“SSgt Hamdan”) searched the motorcycle in the presence of the accused. Using a key provided by the accused, SSgt Hamdan unlocked the seat and opened a covered compartment underneath (the “Motorcycle Compartment”). Inside, he found a red plastic bag marked “A1” under a raincoat. The red plastic bag contained an orange plastic bag marked “A1A”, which in turn contained two separate bundles secured with black tape: “A1A1” and “A1A2”.
Following the discovery, the accused was formally arrested and the Central Narcotics Bureau (“CNB”) was informed. CNB officers arrived at about 7.15am. SSgt Hamdan assisted in opening the motorcycle compartment. CNB Sergeant Muhammad Zuhairi bin Zainuri (“Sgt Zuhairi”) removed the red plastic bag, and passed it—its contents intact—to CNB Staff Sergeant Razif bin Rahim (“SSgt Razif”). In the accused’s presence, SSgt Razif cut open bundle A1A1, revealing a clear plastic wrapper containing a clear plastic packet of granular substance. CNB officers seized the drug exhibits and the accused’s personal belongings, including a black “ZTE” handphone and three SIM cards (two Malaysian SIM cards and one Singapore StarHub SIM card).
Between the day of arrest and 16 March 2018, the accused gave eight recorded statements. These included a contemporaneous statement recorded on the day of arrest, a cautioned statement recorded later that day, and six long statements recorded under s 22 of the CPC on subsequent dates. The seized drug exhibits were submitted to the Health Sciences Authority (“HSA”) on 26 October 2017. The chain of custody was not disputed at trial. HSA analysis confirmed that the drugs contained not less than 21.16g of diamorphine. The court also noted that the accused’s DNA was not found on the exhibits; instead, an unknown male was identified as a major contributor of DNA on the exterior surface of one wrapper.
What Were the Key Legal Issues?
The central legal issue was whether the accused had rebutted the presumption of knowledge under s 18(2) of the MDA. The prosecution relied on both s 18(1) (presumption of possession) and s 18(2) (presumption of knowledge). The accused did not dispute that the MDA presumptions applied, nor that he knew he had brought drugs into Singapore. The dispute was narrower: whether he knew the nature and quantity of the drugs found in his possession.
Accordingly, the court had to evaluate whether the accused’s evidence—his explanations and his account of how he came to possess the drugs—was sufficient to rebut the statutory presumption of knowledge. This required the court to assess credibility, consistency, and plausibility, including how the accused’s recorded statements aligned (or failed to align) with his trial testimony.
A secondary issue concerned sentencing. Once guilt was established, the court had to determine whether the alternative sentencing regime under s 33B was available, which depends on whether the accused qualifies as a courier and whether the Public Prosecutor has issued a certificate of substantive assistance.
How Did the Court Analyse the Issues?
The court began by identifying the applicable statutory framework. Under the MDA, where drugs are found in the accused’s possession and the accused is shown to have brought the drugs into Singapore, the law presumes possession and knowledge. The prosecution therefore established the evidential foundation for conviction. The accused’s task was to rebut the presumption under s 18(2) by showing, on a balance of probabilities, that he did not know the nature and quantity of the drugs.
In assessing whether the accused rebutted the presumption, the court focused on the accused’s version of events. The accused claimed that a person named “Fei Poh” was his drug supplier. He alleged that he was in a relationship with Fei Poh and that she had represented to him that he was transporting about 25g of methamphetamine. He further claimed that he accepted these representations because of their relationship and because of an earlier drug delivery of 25g of methamphetamine he said he had done for her on 9 October 2017. On this basis, he argued that he was unaware that the drugs were diamorphine and that the quantity was far greater than what he believed.
The court, however, found multiple reasons to reject this account. First, it emphasised the accused’s inconsistent testimony and the timing of his defence. The prosecution highlighted that the accused did not raise the key aspects of his defence during earlier recorded statements. In particular, during the cautioned statement, he did not mention that Fei Poh was his supplier, that he thought he was carrying 25g of methamphetamine, or that his belief was based on representations by Fei Poh. The court treated this omission as significant because it concerned fundamental elements of the accused’s explanation for his possession of the drugs.
Second, the court considered the accused’s explanations for why these matters were not disclosed earlier. The judgment extract indicates that the accused attempted to explain inconsistencies and alleged problems with the investigation process, including allegations against an investigating officer (IO Michelle). The court analysed these allegations and found them improbable and not persuasive. It also noted “intrinsic problems” with the accused’s testimony—meaning that even apart from inconsistencies, the internal logic and overall plausibility of his narrative were weak.
Third, the court considered the prosecution’s alternative narrative that the accused was dealing with another person, “Raja”, rather than Fei Poh. The prosecution argued that the accused had been in constant contact with Raja on the day of his arrest and on other occasions when he entered Singapore. The prosecution relied on documentary and forensic evidence, including call records and toll records associated with the SIM cards seized from the accused’s handphone. While the extract provided is truncated, it is clear that the court treated these records as supporting the prosecution’s view that the accused’s story about Fei Poh was an afterthought.
Fourth, the court addressed the forensic point that the accused’s DNA was not found on the exhibits. The court did not treat this as determinative. The presence of an unknown male’s DNA on the exterior surface of a wrapper did not, by itself, establish that the accused lacked knowledge of the drugs. In drug importation cases, the statutory presumptions focus on knowledge and possession, and the court’s credibility assessment of the accused’s account remains central. The court’s reasoning indicates that the absence of the accused’s DNA did not overcome the evidential strength of the presumptions and the court’s adverse credibility findings.
Having considered all these factors, the court concluded that the accused’s evidence was not credible and that he failed to rebut the applicable MDA presumptions. The court therefore convicted him of importation under s 7 of the MDA.
On sentencing, the court applied the MDA’s sentencing structure. It found that the accused was a courier within the meaning of s 33B(2)(a). It also found that the Public Prosecutor had issued a certificate of substantive assistance under s 33B(2)(b). These findings meant that the alternative sentencing regime under s 33B(1)(a) was available. The court then exercised its discretion to impose life imprisonment and caning of 15 strokes, backdating the imprisonment to the date of arrest on 25 October 2017.
What Was the Outcome?
The High Court convicted the accused, Sritharan K Raja Rajan, of importing not less than 21.16g of diamorphine into Singapore under s 7 of the MDA. The conviction followed the court’s finding that the accused failed to rebut the presumptions of possession and knowledge, particularly the presumption of knowledge under s 18(2).
On sentence, the court imposed life imprisonment (backdated to 25 October 2017) and caning of 15 strokes. The sentence was imposed under the alternative sentencing regime in s 33B, because the court found the accused to be a courier and because a certificate of substantive assistance had been issued by the Public Prosecutor.
Why Does This Case Matter?
This case is significant for practitioners because it illustrates how the MDA presumptions operate in practice and how courts evaluate attempts to rebut the presumption of knowledge. Even where an accused does not dispute that he brought drugs into Singapore, the defence may still fail if the accused’s account of knowledge is not credible. The decision underscores that credibility is assessed not only through trial testimony but also through the accused’s earlier recorded statements, including omissions of key defence elements at the earliest opportunity.
For defence counsel, the judgment highlights the evidential importance of contemporaneous disclosure. Where an accused’s later trial narrative introduces a supplier identity, a claimed misunderstanding of the drug type, or a claimed belief about quantity, courts may treat the delayed emergence of these elements as an “afterthought”. The court’s reasoning also demonstrates that allegations against investigating officers or explanations for inconsistencies must be plausible and internally coherent; otherwise, they will not rehabilitate the accused’s credibility.
For prosecutors, the case reaffirms that documentary and forensic evidence (such as call logs and SIM card/toll records) can be used to contextualise and test an accused’s narrative. Even where DNA evidence does not directly implicate the accused, the statutory presumptions and the accused’s credibility remain decisive. For sentencing, the case also provides a clear example of how s 33B is applied when the accused qualifies as a courier and when the Public Prosecutor issues a certificate of substantive assistance.
