Malaysia’s Test for Incompetence of Counsel, Outdated from its inception? [2019] 5 MLJ xviii

Recent Cases


  • R v AS [Bromley Youth Court] 2021

    Trial (Wounding with Intent)

    William was instructed to represent a 15-year-old client in a three-day, two-handed Youth Court trial (Certificate for Counsel granted). The Crown sought to adduce the complainant’s evidence as hearsay under section 116(2)(e) (the complaint had stated he was in fear but also did not want to be seen as a “grass”) and the defendant’s initial account to police (not taken under caution) under section 114(d). William successfully opposed both of these applications in oral and written submissions. At the close of the prosecution case (and after skeleton arguments from both sides), the Court determined that there was insufficient evidence for any reasonable court properly to convict and the case was dismissed. Instructed by Joseph Hill & Co.

  • R v SR [Wood Green Crown Court] 2021

    Trial (being concerned in the supply of cocaine)

    William was instructed to represent a client in a Crown Court trial. The Crown’s case was that the client had been operating a prominent drugs phone over the course of four months. This burner phone had been seized from the police at an address where the defendant and three other persons were arrested (however only the defendant had been charged). The Crown sought to adduce thousands of pages of cell site evidence to attribute the phone to the client as opposed to the other three persons found at the address.

    William was only instructed one working day before the trial (due to previous counsel being unable to deal with the case) and no cell site expert had been instructed (due to late service of cell site data and the client not authorising an application for an adjournment). Notwithstanding these constraints, William was able to successfully highlight the significant limitations of the cell site evidence and secure an acquittal for the client.

  • R v DC [Huntingdon Crown Court] 2021

    Trial (Breach of Restraining Order x 3; Harassment (with fear of violence); Common Assault)

    William was instructed to represent a client in two trials. In the first trial, during Williams’s cross-examination, the complainant claimed to have a “record of pretty much no violence whatsoever” and that he was “not a violent person”. After making an impromptu non-defendant bad character application, William was able to adduce the complainant’s four cautions for common assault, whilst successfully preventing his client’s bad character from also being adduced. The client was acquitted of four out of five charges and subsequently pleaded guilty to a “second strike” bladed article offence (the second trial), resulting in a six-month conditional charge for all convictions. Instructed by Geoff White Solicitors.

  • R v KR [Maidstone Crown Court] 2021

    Dwelling burglary and dangerous driving

    William was instructed to represent a client who had pleaded guilty to dwelling burglary and dangerous driving and not-guilty to two counts of attempted burglary. Following representations being made to the CPS, the Crown offered no evidence on the attempted burglary counts. Citing the case of R v Jessemey [2021] EWCA Crim 175, William successfully argued that the Crown Court’s sentencing powers were limited to those of the Magistrates’ Court and he was able to secure an eight-month suspended sentence for his client. Instructed by Thomas Boyd Whyte.

  • R v JC [Chelmsford Youth Court] 2021

    Conspiracy to supply Class A drugs x 2

    William was instructed to represent a youth client who was charged with conspiracy to supply Class A drugs. Following representations being made to the CPS’ reviewing lawyer regarding the positive NRM referral and the inherent weaknesses of the Crown’s case, the Crown discontinued the charges. Instructed by Paul Martin & Co
