In the case of BLV v Public Prosecutor  SGCA 62, the Singapore Court of Appeal ("CA") found that the offender, who had falsified his evidence and even procured a witness to do the same, had abused the process of the court. In light of such conduct, the CA imposed a significant "uplift" (or increase) on the offender's existing sentence. In doing so, the CA discussed the factors that the court would consider for imposing an uplift which was due to an offender's abuse of the court's process.
In Yap Chen Hsiang Osborn v Public Prosecutor  SGCA 40, the Court of Appeal (“CA”) clarified that section 47(1) of the Corruption, Drug Trafficking and Other Serious Crimes (Confiscation of Benefits) Act (Cap 65A, 2000 Rev Ed) (“CDSA”), which essentially makes it an offense to launder proceeds which represents one’s (i.e. the offender’s) benefits from criminal conduct, applies only to primary offenders (someone who launders the benefits of his or her own criminal conduct) and not secondary offenders (someone who does not himself or herself commit the offence from which the proceeds were originally derived, but launders the proceeds of another person’s crime).
In Public Prosecutor v Dinesh s/o Rajantheran  SGCA 27, the Court of Appeal (“CA”) answered two questions by the Prosecution, regarding the proper interpretation of section 228(4) of the Criminal Procedure Code (Cap 68, 2012 Rev Ed) (“CPC”). Under section 228(4), the court “must reject” a party’s guilty plea if it is satisfied that any matter raised in mitigation “materially affects any legal condition” which constitutes the underlying offence.
In Adili Chibuike Ejike v Public Prosecutor  SGCA 38, the Court of Appeal (“CA”) clarified the operation of the doctrine of wilful blindness and its interplay with the presumption of possession under section 18(1) of the Misuse of Drugs Act (Cap 185, 2008 Rev Ed) (“MDA”)
In Public Prosecutor v ASR  SGCA 16, the Court of Appeal (“CA”) discussed the appropriate sentencing approach for a young offender, the respondent, who committed serious crimes, including aggravated rape and sexual assault by penetration on an intellectually disabled young girl, but who was also himself intellectually disabled, with a mental age of between eight and ten. The respondent was 14 years old when he committed the offences in question. When he was convicted in 2017, he was about 16 ½ years old. He was nearly 18 years old at the time of sentencing, in 2018.
In Mui Jia Jun v Public Prosecutor  SGCA 59, the Court of Appeal upheld the fundamental principle that an accused person should know with certainty, and thus have a full opportunity to meet, the case advanced against him by the Prosecution. For instance, where the Prosecution advances a composite case comprising several facets, the Prosecution should make it explicit if it is seeking a conviction based on any individual facet.
In Zainal bin Hamad v Public Prosecutor  SGCA 62, the Court of Appeal clarified the application of the presumptions under sections 17 and 18 of the Misuse of Drugs Act (“MDA”), which relate to a presumption of trafficking (s17); presumption of possession (s18(1)); and presumption of knowledge (s18(2)). Here, the offenders were convicted by the High Court of drug trafficking offences under the MDA; their appeals to the Court of Appeal were based in part on rebutting these presumptions. The Court of Appeal dismissed their appeals for, inter alia, failing to rebut the presumptions.
