(d) The sentence was wrong in principle; or The sentence imposed was manifestly excessive or inadequate. (See R v. Ball [1951] 35 Cr App. R 164; Loo Weng Fatt v. Public Prosecutor [2001] 3 SLR 313 at para [65]; Public Prosecutor v. UI [2008] 4 SLR (R) 500). [15] In similar vein, the Court of Criminal Appeal in Dookes v. Director of Public Prosecutions [2010] SCJ 71 said at para 177: ... sentencing is not a science of mathematical application of any set formula. It is a normative science rather than a physical science which takes into account the circumstances of the offender as well as the offence and the impact of the offence on the community. A sentence may look to be lenient because it is tailored to fit the offender, the offence and the offended but, in our system of justice, the trial court is the only constitutional institution which is empowered and sovereign in determining which sentence to impose on an offender on the facts of the particular case. An appellate court would scarce intervene unless the sentence is wrong in principle or manifestly 10 [2024] CLJU 1690 Legal Network Series harsh and excessive or unduly lenient. However, even if there is nothing wrong with the principle, the sentence may be increased by the appellate Court if it is unduly lenient. The principle of proportionality pervades through the whole system of justice, in procedure, substance and sanctions." [29] Bearing the above principles in mind, the Court now deals with the issues raised by the accused. THE COURT ANALYSIS AND FINDINGS NON COMPLIANCE OF SECTIONS 31(1) AND 31A OF THE DDA [30] The preliminary point raised by the learned counsel for the accused was the police's non-compliance with section 31(1) of the DDA. The counsel for the accused argued that the accused was arrested merely on suspicion that he was a drug addict, and this does not meet the requirement of section 31(1) of the DDA as the accused was not the target of the police. Hence, the manner of collecting the accused's urine specimen was illegal as it contradicts section 33A(1) of the DDA. Understandably, the accused relied strongly on the High Court case in PP v Jarizal bin Jasni [2024] 7 MLJ 201 to manoeuvre his argument. [31] To address the issue, this Court must first determine whether there were sufficient facts and evidence before the Magistrate to show that PW2 arrested the accused in compliance with section 31(1) of the DDA. That is, whether PW2 had the "reasonable believes" to arrest the accused within the context of section 31(1) of the DDA. [32] Having perused the record of appeal (Volume 2 on page 17), the notes of the proceeding show that when asked by the DPP during the examination in chief, PW2 testified as follows: Q : Ada terima apa-apa aduan? A: Telah dapat maklumat mengenai aktiviti dadah di rumah beralamat no. 1-33a, rumah pangsa Saga Jalan Saga 30 Taman Saga Ampang Selangor. Di mana ketika pasukan saya jalankan pemeriksaan ke atas rumah ini, okt telah datang ke rumah ini dan saya bersama pasukan serbuan telah tahan okt di hadapan rumah ini. [33] As such, there was beforehand information received by the police about drug abuse activity at the unit, and this formed the basis for the police to raid the place. The accused, who arrived at the unit while the police were raiding the place, was arrested by the police together with other individuals. The police brought the accused to IPD Ampang Jaya for the accused to provide his urine specimen for a urine test, and it turned out that the accused's urine was positive for Methamphetamine. No plausible explanation was provided by the accused on how his urine specimen tested positive for Methamphetamine. Hence, the Court found the defence failed to raise reasonable doubt against the prosecution's case. [34] The Court of Appeal in PP v Mohd Safwan bin Husain [2017] 5 MLJ 255 had extensively articulated the scope and application of sections 31 and 31A of the DDA on the pertinent judicial propositions relating to the application of section 31 of the DDA on arrest and the concept of constructive arrest which apply to section 31A of the DDA. Interestingly, the Court noted that both parties referred to the same authority. Still, the accused reached a relatively different conclusion, though the facts of the instant case are similar to PP v Safwan bin Hussain (supra). [35] In PP v Mohd Safwan bin Husain (supra), the facts show that the accused was a police officer who was also charged in the magistrate court for the offence of consumption of dangerous drugs (Methamphetamine) under the same section 15(1)(a) of the DDA. The Magistrate acquitted the accused at the end of the prosecution case. The High Court dismissed the prosecution's appeal as the accused was not a "person arrested" within the meaning of Section 31A of the DDA. The High Court also held that the meaning of arrest in Section 31A of the DDA did not include constructive arrest. The Court of Appeal set aside the High Court's decision and reinforced the principle of constructive arrest. [36] Further, in that case, the Court of Appeal found that there was evidence adduced showing that the police, in that case, had acted on information received beforehand and concluded that there were "reasonable believes" within the context of section 31(1) of the DDA. [37] The Court of Appeal also decided that, essentially, whether there was an arrest before or after the accused gave his urine specimen to the police would entirely depend on the facts and circumstances of each case. [38] Similarly, in the instance case, based on PW2's testimony, there was a shred of clear evidence that PW2 had acted on the information received before the arrest regarding the drug abuse activity in the unit. PW2 and his team were tasked to search and arrest anyone involved in drug-related activity in the unit. PW2 arrested the accused on suspicion that the accused was a drug addict when he arrived at the unit while PW2 and his team searched the unit. Therefore, this Court views that the prior information received by the police justified the police to arrest the accused, which falls within the scope of section 31(1) DDA. [39] Therefore, this Court cannot subscribe to the appellant counsel's notion that the accused must be a target first before the police could arrest an accused under section 31(1) of the DDA. Following this, the Court also views that the decision in Shaaban & Ors v Chong Fook Kam & Anor [1969] 2 MLJ 219 referred by the learned Deputy Public Prosecutor is distinguishable and has no application to the facts of the instant case. [40] Another typical point raised for cases involving section 15(1)(a) of the DDA was the non-compliance with section 31A(1) of the DDA. The accused argued that the police did not arrest him before he gave his urine specimen to the police. [41] Guided by PP v Safwan Hussain (supra), whether or not the police arrested the accused before he gave his urine specimen would depend on the factual matrix of the case. Now, the Court referred to the police report marked as exhibit "P4" lodged by PW2, stating that PW2 had arrested the accused "tahan saspek" to ask him to provide his urine sample, and the test strip result of his urine specimen turned positive for Methamphetamine. The Court also referred to the notes of proceeding found in the Record of Appeal Vol 2 on page 16, where it states as follows: S : Apa tujuan ke tempat kejadian? J : Untuk jalankan serbuan dan tangkapan kes-kes libatkan aktiviti dan penagihan dadah. S : Apa yang berlaku? J : Ketika jam lebih kurang 5.15 ptg, di hadapan sebuah rumah di rumah pangsa di Taman Saga tersebut, saya telah tahan 1 lelaki Melayu dalam keadaan mencurigakan, dan seterusnya saya telah tahan suspek untuk dibawa ke pejabat bahagian siasatan narkotik ipd Ampang untuk jalankan ujian saringan awal pokus ke atas suspek. [42] Therefore, this Court found this case is straightforward. The police had already arrested the accused before the accused was to give his urine specimen to the police. The Court agrees with the learned Depuy Public Prosecutor's contention that even the accused did not deny the evidence that PW2 arrested the accused at the unit. [43] Thus, it is critical to note that there was indeed a direct arrest, not a constructive one, in which circumstantial evidence would generally be applicable. The Court found that the accused's contention on the non-compliance with section 31A(1A) DDA was misconceived because of the apparent statutory provision and case law authority, which is directly on point as decided in PP v Mohd Safwan bin Husain (supra). [44] Having said that, the Court sees no merit in the learned counsel for the accused's argument, urging this Court to follow suit with the decision in PP v Jarizal bin Jasni (supra). [45] Consequently, this Court finds that the second issue raised by the learned counsel that the prosecution's reliance on the Privy Council decision in Shaaban & Ors v Chong Fook Kam & Anor was erroneous is superfluous as the decision in PP v Mohd Safwan bin Husain (supra) is crystal clear that the power of arrest is prescribed by section 31(1) of the DDA. This Court is also bound to follow the Court of Appeal decision based on the stare decisis doctrine, especially since the facts and the laws are similar to the instant case. The presumption under section 37(k) DDA [46] The Magistrate was correct in invoking the presumption under section 37(k) DDA based on the undisputed evidence that the urine screening process carried out by PW2 and PW4 complied with section 31A of the DDA. [47] Besides, the accused failed to rebut the presumption and most of all, there is no evidence adduced by the accused to rebut the said presumption. See Mohamad Radhi bin Yaakob v PP [1991] 3 MLJ
