CACC 72/2023 [2026] HKCA 590 IN THE HIGH COURT OF THE HONG KONG SPECIAL ADMINISTRATIVE REGION COURT OF APPEAL CRIMINAL APPEAL NO 72 OF 2023 (ON APPEAL FROM HCCC NO 286 OF 2020) ________________________
________________________
________________________ J U D G M E N T ________________________ 1.The applicant pleaded not guilty to a single count of trafficking in a dangerous drug, namely 60.85 kilogrammes of a solid containing 51.17 kilogrammes of cocaine, contrary to section 4(1)(a) and (3) of the Dangerous Drugs Ordinance, Cap 134. Following a trial in the High Court before Deputy Judge Eric Kwok, SC (“the judge”) and a jury, he was convicted on 21 March 2023. Subsequently, on 23 March 2023, the applicant was sentenced to 34 years’ imprisonment. 2.By way of a Form XI notice filed on 13 April 2023, the applicant sought leave to appeal against his conviction only. At the hearing of the application, I reserved my decision. This is my judgment. The prosecution case 3.In late March 2019, PW1 was asked by the applicant, a close friend and work colleague whom PW1 had known for 20 years, to lend him his Identity Card. The applicant wished to make a photocopy of PW1’s Identity Card in order to rent an apartment. PW1 acceded to this request. However, the applicant did not tell PW1 the reason for renting the apartment, nor did PW1 ask[1]. 4.About a month later, the applicant asked PW1 to help him move something. At about 3 am on 25 April 2019, they went by separate vehicle to Block K, Sunshine City, Ma On Shan, New Territories (“the Ma On Shan Flat”). Upon entering the building, the applicant and PW1 spent around 8 to 13 minutes in the building trying to locate a particular flat. Assisted by a photograph in the applicant’s telephone, they searched for the flat separately on different floors, during which time PW1 asked the applicant to come over on two or three occasions after PW1 thought he had found the address. Having searched 10 floors, on each of which were situated 8 to 10 flats, they eventually located the Ma On Shan Flat[2]. 5.They entered the Ma On Shan Flat using the applicant’s keys. Inside a room, PW1 saw transparent Ziploc-style bags containing white powder on the floor and asked the applicant what it was. The applicant answered “Coke”, whereupon the applicant offered PW1 money to help him put the Ziploc bags into large nylon bags[3] and take them away. PW1 considered the matter briefly and agreed[4]. 6.Using a trolley, which was already inside the Ma On Shan Flat, the two men carried two large nylon bags of drugs to the applicant’s private car[5]. The applicant was observed by CCTV pushing the trolley, while PW1 opened the door[6]. After the drugs were loaded onto the applicant’s private car, the applicant asked PW1 to swap vehicles without telling him why. With the applicant driving PW1’s vehicle and PW1 driving the applicant’s private car, they drove to Discovery Park, Tsuen Wan in the New Territories[7]. CCTV captured the applicant in PW1’s vehicle entering the car park of Discovery Park first, followed by PW1 in the applicant’s private car[8]. 7.The applicant gave PW1 the keys to Flat B, 15th Floor, Block 8, Discovery Park (“Flat B”) and asked PW1 to bring the two nylon bags of dangerous drugs to Flat B by himself. Having done so using the trolley[9], PW1 returned to Discovery Park car park, where he saw the applicant again. PW1 returned to his vehicle, the door of which was unlocked, and found his car keys in the ignition. At this juncture, the applicant’s private car approached and a person, known as “Ah Fung”, walked over to PW1, who gave him the keys to Flat B. This was the first time PW1 had seen Ah Fung on 25 April 2019. The applicant and PW1 then left Discovery Park by their own vehicles[10]. 8.On 26 April 2019 at about 7 to 8 pm, PW1 was asked by the applicant to go to the Ma On Shan Flat again. They set off from Sheung Shui, where the applicant again swapped vehicles with PW1 and gave PW1 the keys for the Ma On Shan Flat and a mobile telephone. Acting on the applicant’s instruction, PW1 went alone to the Ma On Shan Flat to fetch a sealing machine, some Ziploc bags and gloves while the applicant waited in PW1’s vehicle. PW1 was then asked to return to the applicant’s private car and follow PW1’s vehicle driven by the applicant. They again drove each other’s vehicles to Discovery Park[11]. 9.PW1 drove into the car park alone, while the applicant was outside the car park in PW1’s vehicle. The applicant instructed PW1 to drop off the sealing machine and empty Ziploc bags in Flat B as well as retrieve one Ziploc bag of dangerous drugs from a nylon bag. After putting a Ziploc bag of drugs into a heavy rucksack he had brought with him, PW1 left Flat B and was immediately arrested by the police. Among other things[12], the rucksack, cash in the amounts of HK$26,547.5 and RMB 453, five keys to Flat B and five keys for the Ma On Shan Flat were found on PW1. Besides the Ziploc bag of dangerous drugs, the rucksack also contained the sealing machine and some empty Ziploc bags, which PW1 had forgotten to drop off at Flat B as instructed[13]. Inside Flat B, the police found an electronic scale and 38 Ziploc bags of suspected cocaine in the two nylon bags. Including the one being carried by PW1, the 39 Ziploc bags seized held a total of 60.85 kilogrammes of a solid containing 51.17 kilogrammes of cocaine, the street value of which was HK$66,774,390[14]. 10.Meanwhile, the applicant, who had parked PW1’s vehicle in the Discovery Park car park, was intercepted and arrested by DPC 9604 (PW3)[15]. Upon searching the applicant and PW1’s van, PW3 found, inter alia, (i) a Samsung mobile telephone in the applicant’s hand (P126); (ii) a Samsung mobile telephone with rose patterned case in the applicant’s shorts pocket (P128)[16]; (iii) 12 telephones in PW1’s van; (iv) car keys for PW1’s vehicle and a Range Rover; (v) cash of HK$2,096.8 and RMB 2,032; and (vi) two Octopus cards. Without examining the telephones, PW3 put the two found on the applicant, namely P126 and P128, in an unsealed evidence bag and the 12 telephones found in PW1’s vehicle in another unsealed evidence bag. He left notes on these bags differentiating the origins of the seized telephones and passed them to policewoman WDPC 4153 (PW4), who guarded the applicant after his arrest[17]. 11.PW4 interviewed the applicant the following day, 27 April 2019. Before the interview, which was video recorded, the telephones seized from the applicant and PW1’s van were rearranged. Since two of the telephones found in PW1’s vehicle belonged to PW1, PW3 gave them to officer DPC4522 (PW2), who had arrested PW1. Inadvertently, PW4 mixed up the two telephones found on the applicant (including P128) together with the remaining ten telephones found in PW1’s vehicle for ease of storage. At the time, PW4 thought the telephones were not “major exhibits” in the case and it was unimportant to differentiate whether they were found on the applicant or in PW1’s vehicle. She had forgotten where the notes left by PW3 were or whether she had thrown them away. During the video recorded interview, PW4 did not differentiate the 12 telephones when questioning the applicant about them[18]. 12.P128, one of the two telephones found on the applicant when he was arrested, contained WhatsApp messages between the applicant[19] and an estate agent Ms Liu Haixin (PW6)[20]. In April 2019, PW6 had helped a customer rent Flat B. She said she had met the customer twice in person and it was the same person who signed the tenancy agreement for Flat B as tenant. PW6 did not check this person’s identity when the agreement was signed as she had already been given a supposed copy of the tenant’s Identity Card. In her testimony, PW6 said the man who signed the tenancy agreement was not the same one shown on the Identity Card copy. She did not find this unusual and agreed that she had not mentioned this matter in her witness statement[21]. 13.The prosecution case was that the applicant used PW1’s Identity Card copy to rent Flat B and conveyed the 39 Ziploc bags of cocaine from the Ma On Shan Flat to Flat B on 25 April 2019. On 26 April 2019, it was also the applicant who instructed PW1 to fetch one bag of cocaine from Flat B. During the operations on 25 and 26 April 2019, the applicant, who remained in the vicinity, used and supervised PW1 to move the dangerous drug while he kept a suitable distance[22]. 14.PW1 pleaded guilty to the same offence the applicant faced and subsequently gave evidence against the applicant. During his testimony, PW1 needed to correct himself on multiple occasions after being shown various CCTV images. For example:
The defence case 15.The applicant elected to give evidence but did not call any other evidence. His defence was a denial of knowledge of the presence of the dangerous drugs. Although he admitted involvement in moving the Ziploc bags, some of which bore traces of his and PW1’s DNA[28], the applicant had no idea that they contained dangerous drugs and was told by PW1 that they were fillers. 16.In essence, the applicant’s case was that he was tricked by PW1. On 25 April 2019, PW1, who was a close friend and colleague who wanted to test drive the applicant’s private car with a view to buying it, suggested to meet near Sunshine City, Ma On Shan at about midnight. The applicant arrived at about 00:45 hours with a colleague Ah Fung, who knew PW1 and had a test drive of the private car before PW1. PW1, who drove his van to Sunshine City, gave the applicant the access card and keys for the Ma On Shan Flat because the applicant needed to use the toilet urgently. The applicant was seen in CCTV footage going up alone in a lift at around 00:53 hours. Having stayed in the Ma On Shan Flat for around 10 minutes and noticing nothing abnormal, the applicant went back to PW1 for the test drive and returned the Ma On Shan Flat’s access card and keys. After the test drive session, PW1 told the applicant that he wanted to extend the test drive. It happened that he needed to move something from Ma On Shan to Discovery Park. PW1 asked the applicant to join him[29]. 17.The applicant and PW1 went up to the Ma On Shan Flat at around 03:00 hours on 25 April 2019. There was no episode of searching 10 floors or so to locate the flat. Since he was eating a snack, PW1 asked the applicant to press the floor button in the lift. At that time, the applicant had forgotten which floor he went to earlier, and so pressed the wrong floor. When the lift stopped, PW1 told the applicant that it was not the right floor. However, instead of using the lift again, PW1 suggested walking downstairs since it was quicker. Having walked down 10 odd floors, they arrived at the Ma On Shan Flat and PW1 opened the door. After using the toilet in the Ma On Shan Flat again, the applicant saw PW1 in a room tidying Ziploc bags that contained white powder. PW1 told applicant that they were fillers. The applicant had never seen dangerous drugs or used fillers before. Consequently, he believed PW1 and agreed to help PW1 put the Ziploc bags into two big bags. In doing so, he did not notice an electronic scale in one of the big bags[30]. 18.The applicant pushed the trolley carrying the two big bags to the car park. The two big bags were loaded onto the applicant’s private car, which was then driven by PW1 to Discovery Park while the applicant followed in PW1’s van. After arriving at the car park of Discovery Park, PW1 pushed away the trolley with the two big bags and gave the applicant back his car keys. With PW1 away, the applicant intended to leave, only to discover that he had forgotten to return the keys for PW1’s van. He waited for PW1’s return, during which he got some food from a 7-Eleven store. When PW1 returned, he asked Ah Fung to pass the van’s keys to PW1. 19.On 26 April 2019, the applicant met PW1 in Fanling at around 20:00 hours and let PW1 take his private car. They arranged to meet at Discovery Park at around 22:00 hours for the applicant to collect payment as well as documents for registration. After the applicant arrived at Discovery Park, he was suddenly arrested by the police at the car park without seeing PW1 at all. As for Flat B, the applicant said it was PW1 who asked him to liaise with a property agent on behalf of PW1. P128, the telephone the applicant admitted using to exchange messages with the property agent, was previously given to him by PW1 and was returned to PW1 on 23 April 2019[31]. The defence insisted that P128 was found inside PW1’s van instead of on the applicant’s person[32]. 20.The applicant’s counsel at trial invited the jury to consider these particular points in favour of the defence:
The summing-up 21.The judge reminded the jury of the burden and standard of proof, and made clear that the applicant “does not have to prove his innocence”[45]. He explained to them how to function as a jury and assess the evidence, including how to draw inference and what was circumstantial evidence[46]. The judge gave the jury directions on law, including the elements of the offence[47]. He reminded the jury that PW1 testified against the applicant in the hope of getting a lesser sentence and, accordingly, his evidence should be approached with caution[48]. When summarising the respective cases of the parties and the issues at trial, the judge said this[49]:
22.Having summarised the evidence, the judge reiterated the trilogy of issues at trial[50]:
The grounds of appeal 23.Acting in person[51], the applicant has advanced three grounds of appeal against conviction in his homemade written submission dated 27 August 2025[52]:
24.In Ground 3 regarding the judge’s partiality, the applicant referred to the relevant principles stated in HKSAR v Zhu Jinni[57] and Lin Ping Keung v HKSAR[58], and complained specifically against the following passages of the judge’s summing-up:
The respondent’s reply 25.Ms Winnie Mok, for the respondent, submitted in respect of Ground 1 that the judge has clearly and properly directed the jury on the issue of knowledge. Apart from the passages quoted in [21] and [22] above, Ms Mok pointed out that: (a) the jury was reminded by the judge that they could only convict the applicant if they were sure that the applicant knew the content of the Ziploc bags were dangerous drugs (AB, pp 22S-23C); (b) the applicant’s defence argument and evidence were repeatedly highlighted by the judge (eg at AB, pp 24A-G & 39Q-40M). The complaint in this ground cannot, therefore, be substantiated[59]. 26.In respect of Ground 2, Ms Mok submitted that the judge has properly directed the jury as to the burden and standard of proof (AB, pp 19Q-20A), adequately explained the meaning of direct and circumstantial evidence (AB, pp 20H-22E) and clearly warned the jury to approach PW1’s evidence with caution, bearing in mind that PW1 had strong incentive to testify against the applicant (AB, p 24M-U). Although the judge did not specifically touch on the nature of “Admitted Facts”, no prejudice to the applicant was caused since these facts were largely formal evidence, which was not disputed by the defence. She contended that the judge was right not to mention PW1’s previous conviction in his summing-up. As for the inconsistencies of the prosecution witnesses’ evidence, they had been fully detailed by defence counsel in her closing address to the jury. The judge was again correct in not commenting too much on the evidence lest he appeared to usurp the role and function of the jury[60]. 27.Ms Mok disagreed that the summing-up was unfair or imbalanced. The judge not only warned the jury about the risk of PW1 falsely accusing the applicant (AB, pp 24N-25C), he also summarised the defence case in great detail and with due emphasis (AB, pp 39F-42I). Nothing in the summing-up showed that the judge presented the prosecution case in a more favourable manner than the defence. The jury had already been given a comprehensive closing speech by the defence counsel. It would only be inappropriate for the judge, who was neither the defence nor the jury, to sow every seed of doubt about the prosecution case in the defence’s favour. Ground 3 thus lacked merit[61]. Consideration 28.This was a classic jury case of whether PW1 was to be believed beyond a reasonable doubt in view of the deficiencies in his account, and in the light of the applicant’s own evidence. It was for the jury not the Court of Appeal to make determinations of fact. I have set out the evidence and the arguments in some detail, as well as the relevant directions in the summing-up to demonstrate that the judge conducted a very fair and comprehensive summary of the case. I can see no errors of law. I agree with Ms Mok’s submissions. The evidence was overwhelming, once the jury decided that they believed PW1 for all the apparent weaknesses in his evidence. 29.There are two matters I would like to mention. Firstly, in the applicant’s written submissions, it is argued at [20(C)(v)] on page 13 that the prosecution and the defence both “agreed that [PW1] did not have any mobile telephone” when he was arrested on 26 April 2019. The complaint was that this contradicted PW1’s evidence of having received from the applicant a telephone earlier that day for communication, whereas the judge failed to point this out. It seems to me that this argument is based on speculation. Although the Admitted Facts did not state that PW1 had a telephone when he was arrested, the available material does not show that there was any evidence or agreement that PW1 did not have a telephone when he was arrested by PW2. Defence counsel’s closing address did not mention this nor did she use it to discredit PW1. 30.Secondly, the applicant complained that the judge was unfair when making adverse comments on the defence case in passages quoted in [24] above. However, on several other occasions, the judge’s comments were very much in favour of the defence:
31.Having examined the papers carefully, I do not see any reasonable grounds of appeal against conviction and the application is refused. The applicant is nevertheless reminded that he has the right to renew his application for leave to appeal against conviction to the full Court of Appeal, but he is also warned that the Court has the power to order the loss of any time spent in custody pending the determination of the appeal, if it were to come to the conclusion that there was no justification for the renewal of the application. 32.I should add this in relation to sentence. Although there is no appeal against sentence, the Court has, since sentence was passed on the applicant, issued revised guidelines[62] in relation to large or very large quantities of dangerous drugs, including cocaine; and, furthermore, held that the prevailing sentencing limit for the offence of trafficking in dangerous drugs is 35 years’ imprisonment[63]. It is a matter for him whether he wishes to mount any application out of time in relation to sentence, given that the sentence after trial for 30 kilogrammes of cocaine on a purely arithmetical basis would now be 30 years’ imprisonment. He received 34 years’ imprisonment after trial for trafficking in 51 kilogrammes of cocaine.
