21 One of the underlying rationales for the deeming provision is the fact that a person will not be an occupier unless they have a requisite degree of control over the premises so as to be able to control access to it,[10] and hence be able to control access to the substance which they are alleged to possess. So a person who has control over a building will have possession of a pocket book dropped within it.[11] A person driving a car will have possession of the items in the boot.[12] A person with the sole key to a locker will have control over the items in the locker.[13] Even in a shared house, a person who can control access by hiding an item will have the necessary degree of control over it.[14]
22 The directions given to the jury by his Honour concerning occupation of the premises are not in issue nor is it alleged that the evidence was insufficient to establish the applicant's occupation. The contention advanced on the applicant's behalf under grounds 1 and 3 is that the jury was not adequately directed as to what would constitute possession so that the jury could determine whether it had been established by the Crown or disproved by the applicant.
23 A person proved to be in occupation of the premises is deemed to be in possession, as it is understood at common law, unless he proves that he was not in possession of the substance.[15] The elements of common law possession are "the corpus and the animus, the first consisting in a certain physical relationship between the propositus and the thing, the second consisting in a certain mental attitude on his part towards it."[16] Possession requires both physical dominion over the subject matter and an intent to exercise control.[17] That is to say, for the person to be in possession, there must be physical control of the subject matter accompanied by the intention to exercise control. At common law, knowledge of the presence of the item by the occupier of the premises will generally provide the basis from which the necessary intent can be inferred.[18]
24 If the jury were satisfied that the drugs were on premises occupied by the accused,[19] the physical element of custody or control of the substance and the mental elements of knowledge and intent to possess or control the substance[20] would be deemed to be satisfied as a consequence of s 5.[21] To overcome the effect of the deeming provision in s 5, an occupier of a premises must satisfy the jury, on the balance of probabilities, that he or she was unaware that the drug was on the premises or had no intention to exercise control over the drug or the place where it was kept.
25 The evidence as to the applicant's state of mind (knowledge and intent) was to be found in his answers in his record of interview. He had told the investigators that he occupied the master bedroom at 7 Renbold Place where the drugs were found in his bedside drawer. He said that he had no knowledge of any of the heroin found by the police in the house and had never seen any heroin in the house. He denied that he had ever taken any heroin into the house or been in possession of any heroin and did not know to whom the scales and balloons located in his bedroom belonged. He said that he did not know that the heroin was in his bedroom. The jury rejected his explanation.
26 A conclusion that a person is the occupier within the meaning of section 5 of the Act may, depending upon the circumstances, leave open an issue as to whether they knew of the presence of or were in "control" of the item found on the premises.[22] Deemed possession would be disproved if it were shown, on the evidence, as more likely than not that one of these elements of possession did not exist. The applicant would not have possession of the heroin if he did not know of its presence or intend to exercise dominion or power over it.[23]
27 As in the present case, if an issue arises from the evidence as to whether the occupier had knowledge of the presence of the substance, a direction to the jury as to that element would be required. Similarly, where there is evidence that the occupier did not intend to exercise control over the substance, a direction to the jury as to that element of possession would be required.
28 The trial judge, in directing the jury as to what it was the applicant would have to establish if he was to disprove possession, instructed the jury that the burden thrown upon the applicant would only be discharged if he satisfied the jury on the balance of probabilities that he did not know the drugs were on the premises or that the powder contained heroin. This direction was said to be deficient. It was submitted that proof that the applicant had a knowledge that the substance was on his premises and knew what that substance was, did not establish the necessary animus to exercise control over the substance and would therefore be insufficient to constitute possession. Mr Nash QC, who appeared with Mr Dickinson on this appeal, argued that proof that the applicant occupied the premises, including a bedroom, and had knowledge of the presence of the drugs, did not establish that he had possession in the absence of proof that he exercised control over the drugs. Based upon this proposition it was submitted that the trial judge was bound to direct the jury that the applicant would disprove possession if, on the balance of probabilities, he established a lack of control or a lack of intent to control the heroin that was on the premises. The directions given were said to be inadequate as they did not involve a direction as to the element of an intent to control the substance.
29 Counsel for the applicant further submitted that such a direction was necessary because there was evidence from which the jury could infer that the applicant did not have control or the intention to control the drugs. Contrary to the applicant's defence at trial, it was submitted in this court that there was a view of the facts open that the applicant knew of the presence of the drugs on his premises and in particular in his bed side drawer, that they belonged to Vo, were being used by Vo for trafficking heroin from the premises, and that the jury could have inferred that the applicant was not exercising control over them and did not intend to do so. Such facts, if made out by the evidence, would be sufficient to discharge the applicant's burden of proof. It was asserted that as such findings were open on the evidence, a direction as to the elements of possession was necessary.
30 These submissions cannot be sustained. Once the Crown established the applicant's occupation of the premises, carrying with it the legal consequence of deemed possession, the Crown had established all the elements of possession, including the applicant's intent, unless the applicant was able to prove the contrary. There was no evidence that could support a finding, on the balance of probabilities, that any of the drugs found at the time of the search in fact belonged to Vo alone. Moreover, even if there had been sufficient evidence for the jury to have made such a finding, there was no evidentiary material upon which the applicant could rely to establish that he did not intend to exercise control in relation to those drugs. Counsel for the applicant acknowledged that a person may have possession of something that belongs to another or is part of another person's business.
31 Mr Nash properly conceded that the only source from which such evidence could have come was the applicant's record of interview and stated candidly that he was unable to suggest that any answers of the applicant could support such a contention. There were no answers that gave rise to or could positively support the hypothesis that the applicant, whilst aware that Vo's drugs were concealed in his bedside table, had no control over them and did not intend to exercise control over them.
32 In the absence of some evidence to overcome the effect of the deeming provision, the trial judge correctly determined that the only issue raised by the evidence concerned the applicant's knowledge of the presence of the drugs. Moreover, as hereafter appears, the defence, for forensic as well as evidentiary reasons, only wished to pursue the issue of the applicant's knowledge of the presence of the drugs at the premises. It was not necessary that the trial judge direct the jury as to an element of possession which was not open on the evidence or raised by the defence as an issue at the trial.
33 Ground 3 concerns the directions which it is asserted should have been given following the jury question raised during the course of their deliberations. It is said that the jury question emphasised the need to give the direction the subject of ground 1. The jury asked: "[I]f Tran knew that Vo was trafficking drugs from the house and that there were drugs in the house but he was not involved in this business, it was Vo's business only, is Tran guilty of trafficking?" Mr Nash submitted that the jury question, which he assumed was directed to the issue of possession and not trafficking, showed that there was a live issue as to whether the applicant had possession or control of the drugs. He submitted that the question showed that the jury thought that it was Vo who was trafficking from the premises and that the applicant was not involved in Vo's business.
34 Defence counsel at the trial told the trial judge that the question asked by the jury was "impossible to answer" and expressed concern that what the applicant knew or may have known of Vo's trafficking in drugs had to be the subject of evidence and not mere speculation by the jury. He described the question whether the applicant knew that Vo was trafficking drugs from the house as "hypothetical". Defence counsel strenuously resisted any direction that would be based upon the applicant's awareness of the presence of drugs or that trafficking in heroin at the premises took place from the house. He submitted that there was no evidence that established that the applicant was aware of the presence of the drugs. Counsel approved the direction proposed by the trial judge to answer the jury question - namely that the only basis upon which they could find guilt was through finding that the applicant was the occupier and thus deemed to be in possession.
35 The answer which his Honour gave the jury was as follows:
