(e) the trial judge disregarded the physical condition of the appellant who suffered ischemic stroke and hence opined that the appellant could carry the drugs which was without any medical or evidentiary basis at all. Issue on Possession [8] In the instant case, it is not in dispute that the arrest took place in consequence of earlier information of a description of a man trafficking drugs in an area where the defence counsel says is infested with drug problems. PW2 was the arresting officer and he had led a team of police officers who did not give evidence at all more so when there was already an allegation at the prosecution stage that the appellant was incapacitated on medical grounds and his right hand which was partially incapacitated by stroke was not capable of carrying the drugs or able to run. [9] PW2 also said before the arrest when he introduced himself as police officer, the appellant ran away and was apprehended by two other team members. However, during cross-examination he conceded that he did not run. [10] It is important to note in the instant case that only PW2 gave evidence in respect of arrest and receipt of drug as well as the appellant had ran and subsequently was detained by two other team members. There was no other witnesses of the team who gave evidence to say 10 that the appellant was not incapacitated as alleged by the defence. It must be asserted here that courts generally have taken the position that evidence of police officers are worthy of belief with a caveat to say that Malaysian jurisprudence does not entertain pure self-serving evidence of a police officer’s oral testimony without sufficient corroborative evidence. In the instant case, for example, if PW2 evidence is expunged the prosecution case would collapse as there was no credible nexus to the drug and appellant. [11] There was also no credible DNA evidence or fingerprint evidence to connect the appellant exclusively with the said plastic bag where drugs were found. In short, the learned judge had substantially relied on PW2 evidence to call for the defence of trafficking. At this time and era where smart phones has become the norm for ordinary persons to carry, it would not have been difficult for other team members to record the events to place probative value to the prosecution stage more so when it was said to be a pre-planned raid based on prior information as well as description. There was no such evidence of photos or recording of the incident produced before arrest, save as to photos related to after arrest. If such recordings were taken and produced, it would have given high probative force. In addition, it would have been relevant under the principles related to res gestae, thereby giving high probative value. [See Mohd Khayry bin Ismail v Public Prosecutor [2014] 4 MLJ 317]. [12] In consequence of lack of cogent evidence as well as credible evidence to link the appellant to the drugs, the court was obliged to rule that a prima facie case has not been established. Drug offences are serious offences and court should not easily entertain weak evidence to call for the defence. To ascertain what is weak evidence in drug case in 11 an objective manner needs the application of common sense jurisprudence. One methodology to do so will be for the trial judge to place in the shoes of the accused and ask the pertinent question as per this case, whether the single evidence of PW2 with no credible forensic nexus to the drugs will be sufficient to reach a prima facie case which ultimately may lead to a conviction of death. In doing so, the learned trial judge must keep in mind the well established jurisprudence related to coherent as well as credible evidence to reach the prima facie case as stated in a number of cases. To name a few are as follows: (i) Looi Kow Chai v PP [2003] 1 CLJ 734; (ii) PP v Mohd Radzi bin Abu Bakar [2005] 6 AMR 203. In PP v Mohd Aszzid Abdullah [2008] 1 MLJ 281, it was stated: “The two stages of criminal proceedings are captured in s 173(f) of the CPC for trial before the subordinate courts and s 180 for trials before the High Court. There was a statutory duty for the prosecution to establish a prima facie case before the court is obliged to call for the defence. A prima facie case materially consists of more than two concepts related to EA. They are issues relating to standard of proof and weight of evidence or also referred to as probative value or probative force. A prima facie case is established where there is sufficient evidence to be called upon to answer and evidence adduced by the prosecution must be such that it can only be overthrown upon hearing evidence in rebuttal by the defence to the prosecution case. The force of the evidence adduced must be such that, if unrebutted, it is sufficient to induce the court to believe in the existence of the facts stated in the charge or to consider its existence so probable that a prudent man ought to act upon the supposition that those facts that exist did not happen. The court must at the close of the prosecution case undertake a positive evaluation of the credibility and reliability of all the evidence adduced so as to determine whether the elements of the offences 12 have been established. The test is: is the evidence sufficient to convict the accused if he elects to remain silent? If there is any such doubt there can be no prima facie case. As the accused can be convicted on the prima facie evidence, it must reach a standard which is capable of supporting a conviction beyond reasonable doubt.” [13] In theory, prima facie evidence is not related to evidence which we normally say as conclusive evidence or evidence beyond reasonable doubt. To establish prima facie case, the law only requires the prosecution to demonstrate sufficient credible evidence, establishing each essential ingredient of the offence to establish guilt on the basis if the accused has no answer to the charge, he must be convicted. The answer to the charge will only come at the defence stage and if he does not answer or give satisfactory explanation, then what was established as a prima facie case becomes a case where the prosecution has established the case beyond reasonable doubt. Even at prima facie stage, the court has to scrutinize the prosecution evidence strictly which is normally referred to as a maximum evaluation process of prosecution evidence in relation to each essential ingredient of the offence. The theory related to prima facie or beyond reasonable doubt is one related to mental gymnastics which the court is obliged to exercise correctly without any elements of prejudice against the accused in favouring the prosecution’s version or evidence. [See PP v Sukumaran a/l Sundaram [1999] 4 MLJ 426]. [14] PW2’s evidence per se on the factual matrix of the case in our view, is a weak evidence and not sufficient to call for the defence. In saying so, we must distinguish cases of drug trafficking where a passenger at the airport upon arrival is found to have drugs in his 13 handbag or luggage when the prosecution has established the nexus to the bag as well as the passenger. The instant case is not the same. To put it crudely, the prosecution in this case is inviting the court to hang a person purely on the evidence of PW2 without showing some credible nexus to the bag as well as the drugs when there was clear evidence to say that the arrest was related to an informer and the DNA evidence was not conclusive and/or exclusive to implicate the accused. [15] The learned counsel for the appellant in reliance of Muhammad bin Hassan v PP [1998] 2 CLJ 170 asserts that: “It is trite that the Prosecution must prove the element of custody and control and the trial court must make an affirmative finding of having had "in custody or under...control anything whatsoever containing" the drug, whereas to arrive at the presumption of "trafficking" under s. 37(da), a finding of being "in possession" of the drug is necessary, in addition to proof of the relevant minimum quantity specified.” Section 37(d) of DDA 1952 says: “(d) any person who is found to have had in his custody or under his control anything whatsoever containing any dangerous drug shall, until the contrary is proved, be deemed to have been in possession of such drug and shall, until the contrary is proved, be deemed to have known the nature of such drug.” [16] Section 37(da) in essence, which relates to the weight of drugs as well as lack of authority to possess drugs says that “should be presumed until the contrary is proved to be trafficking in the said drugs”. 14 [17] Both the sub-sections and its nexus and commonality was dealt in great detail by the Court of Appeal in the case of Phrueksa Taemchim (Thailand) v PP [2013] 10 CLJ 1, where the court held: “(1) Section 37(d) may become operational the moment custody and control of the drugs is established. However, without proof of knowledge it is insufficient to apply the presumption of possession. Mere knowledge alone without exclusivity of either physical custody or control or both is insufficient in law to constitute possession, let alone trafficking. Section 37(da) can only become operational once custody control, knowledge with actual possession has been established (paras 10 & 11 ).
