Selected Cases:
HKSR v Mak-Hiu laam (HCCC 309/2024; HCCC 310/2024):
As sole advocate, secured a Not Guilty Verdict after a 7 days trial for the defendant (D2) who was charge with trafficking in dangerous drugs. The prosecution case involved multiple types of controlled substances discovered from a residential flat whom the defendant shared with a cohabitant (D1). The case was based primarily on circumstantial evidence, including the presence of drugs within the premises, forensic DNA findings on packaging, and an alleged inference of joint possession arising from cohabitation
HKSAR v Atrium Building Materials Engineering (HCMA 86/2025 on appeal from KCS 9610/2024):
Acting as sole defence counsel at trial and on appeal, successfully overturned a conviction under the Occupational Safety and Health Ordinance (Cap. 509). The client, a subcontractor, had been convicted and fined following a workplace accident involving a worker who fell while carrying out demolition works. At trial, the trial magistrate found the employer had failed to provide necessary safety information, instruction, training and supervision at the material time.
The High Court allowed the appeal and quashed the conviction:
o The relevant work (ceiling demolition) had not yet commenced at the time of the accident;
o The worker acted without instruction and outside the planned system of work;
o Safety obligations under OSHO apply only to what is “reasonably practicable” and necessary at the material time;
o The trial court erred by assessing liability based on hypothetical future tasks.
HKSAR v Cheng Wai Kit (CACC 24/2019) [2021] HKCA 713:
As sole advocate, acted for the applicant. The applicant was found guilty of trafficking in dangerous drugs after trial by jury in the High Court. The appeal turned on firstly, the propriety of jury direction as to the applicable standards in considering the defendant’s evidence and secondly, money found in possession of defendant. Leave granted on both grounds.
HKSAR v Kwan Wing Yan (CACC 166/2019) [2021] HKCA 1397:
As led junior, acted for the applicant. Two grounds of appeal against conviction were advanced. The first ground turned on whether the judge when making his ruling on special issue, did not limit his finding on voluntariness, contrary to the principles set out in Thongjai. The second ground concerns the applicability of HKSAR v Chan Hing Kai [2020] 1 HKLRD (concerning “lack of puttage”) in a trial by single judge. Leave granted on both grounds.
HKSAR v Leung Wai Kit (CACC 292/2019) [2021] HKCA 1408:
As led junior, acted for the applicant. Leave granted to appeal against conviction. The sole ground of appeal turned on what circumstances justify the need to direct the jury on the “lack of puttage” and if so, the proper bounds in doing so.
HKSAR v Ho Ping Sang (ESCC 650/2021)
Led by Mr. Edwin Choy S.C., fatal accident involving a speed boat. Defendant, the coxswain was charged with endangering others at sea under s.32 of Cap 548. Acquitted.
