District Judge Vince Gui:

Introduction

1. In Prakash s/o Mathivanan v PP and other appeals [2025] 4 SLR 1386 (“Prakash”), a three-judge coram of the General Division of the High Court established the appropriate sentencing approach for offenders convicted of an amalgamated charge under s 124(4) of the Criminal Procedure Code 2010 (the “CPC”). In the present case, parties dispute how should that sentencing approach be applied.

2. The dispute centres on the definition of the “single incident of the offences committed” which was termed the “base offence” in Prakash (at [129(a)]).

• (a) The Defence submitted that the base offence should reflect the “average amount deceived” in each cheating incident.

• (b) The Prosecution submitted that it should reflect the aggregate amount cheated across all cheating incidents.

3. I prefer the Prosecution’s interpretation of Prakash. This is my judgment, beginning with the facts.

Background facts

4. The accused, Chai Song Lin, worked as an assistant manager at the Allbest Human Resources Pte Ltd (the “Company”), a foreign domestic worker agency, from June 2022 to March 2025. His responsibilities included engaging clients, selling the Company’s services, and directing clients to pay deposits and processing fees to the Company’s OCBC bank account through various payment methods including PayNow.¹

5. In September 2024, the accused formed an intention to divert client payments to his personal CIMB bank account. He executed this plan by changing his personal PayNow account name from “Derek” to “1st Allbest Human Resource Pte Ltd” and providing clients with QR codes linked to his personal bank account. When clients scanned these codes, they saw the company name as the recipient and believed that they were paying the company’s bank account.²

6. Between 19 September 2024 and 3 March 2025, the accused diverted $92,508.40 across 72 separate incidents using this deception. To maintain appearances, he transferred $3,816 to the Company’s bank account.³

7. The scheme was exposed when the accused’s supervisor noticed a discrepancy between the accused’s high sales record and the Company’s low sales receipts. When confronted on 6 March 2025, the accused initially lied about clients delaying payments. He only confessed to the misappropriation when his supervisor threatened to verify his story with the clients.⁴

8. On his supervisor’s demand, the accused made partial restitution of $10,000 on 7 March 2025. His His supervisor subsequently reported the matter to the police which led to the accused’s arrest.⁵

9. The accused pleaded guilty to one count of cheating under s 420 Penal Code 1871 (the “Penal Code”). The charge was amalgamated under s 124(4) of the CPC, which treats the multiple incidents as a single course of conduct, providing for enhanced punishment under s 124(8)(a)(ii) of the CPC.

Parties’ submissions

Prosecution’s submissions

10. The Prosecution sought a sentence of 17 – 18 months’ imprisonment.⁶

11. Specific deterrence is justified:⁷

• (a) The accused offended on at least 72 occasions over five months. He was a serial offender. Serial offender should generally be treated more harshly.

• (b) The offence was carefully planned.

12. The amount misappropriated was $88,692.40 (sans $3,816 he transferred to the Company). The outstanding loss after restitution stood at $78,692.40.⁸

13. The accused abused the substantial trust reposed in him by the Company.

14. The Prosecution referred to factually similar sentencing precedents under s 408 of the Penal Code.⁹

Mitigation plea

15. The Defence sought no more than 10 months’ imprisonment. In this regard:¹⁰

• (a) The “base offence” would be a singular incident of cheating of $1,248.84 (being $92,508.40 divided by 72 instances).

• (b) The appropriate sentence for the “base offence” would be an imprisonment term of 1.5 months.

• (c) The amounts cheated per incident (between $60 and $3,500) is significantly lower than sentencing precedents.

• (d) The appropriate starting point sentence should be an imprisonment term of no more than 15 months.

• (e) Calibrating downwards for the “severe episode of Major Depressive Disorder” which the accused was suffering from and his early plea of guilt, the appropriate sentence should be an imprisonment term of 10 months.

Prosecution’s Reply

16. The Prosecution made three points in reply. The first two overlapped with the queries that I posed to the Defence at the hearing.¹¹

17. First, the psychiatric report adduced by the Defence should be given little weight.

• (a) The offending period (September 2024 to March 2025) was distinct from the period covered by the psychiatric report. The psychiatric report adduced by the Defence stated that the accused was suffering from Major Depressive Disorder between May to September 2024.

• (b) The report was heavily qualified as it was premised entirely on the accused’s self-reporting.

• (c) The report suggested that the accused had committed only one instance of cheating in September 2024. This was not true.

18. Second, it was not clear why the Defence submitted that the offender in PP v Tan Keat Siang [2020] SGDC 220 was of higher culpability. There was no basis to give such a huge discount in the sentence in the present case.

19. Third, the Prosecution disagreed with the Defence’s conception of a “base offence” in Prakash. Nowhere in Prakash did the court suggest that it should divide the total quantum by the number of cheating instances. In fact, the court suggested that it was impractical and impossible to do so. The correct approach is to identify the base sentence for the aggregate sum cheated, i.e. $92,508.40, and then give an uplift for the 72 instances of cheating to reflect the persistence of the offender. It is important for the court to consider the case holistically.

Decision

20. I first summarise the court’s approach to sentencing an offender convicted of an amalgamated charge under s 124(4) of the CPC, focusing on aspects relevant to the present case (Prakash at [129]):

• (a) First, the court must identify the punishment prescribed for a single incident of the offences committed, under what is termed the “base offence”.

• (b) Second, the court will determine the appropriate starting point sentence. The assessment would be done based on:

  • (i) a holistic assessment of the offender’s culpability over the entire course of conduct and the offender’s overall culpability, such as the duration and frequency of the offending conduct (for example, an offender who has repeated the offence multiple times over a sustained period would have demonstrated greater recalcitrance, which is an aggravating factor); and

  • (ii) the aggregate harm caused. It would not be necessary to isolate the harm caused by each of the constituent incidents of offending.

• (c) Third, the court considers the relevant offender-specific aggravating and mitigating factors before deciding whether adjustments are required to the starting point sentence.

21. I shall apply the Prakash Framework to the present case.

First Stage of the Prakash Framework: Punishment prescribed for the base offence

22. I agree with the Prosecution that the proper approach is to identify the base sentence for the aggregate sum cheated at the first stage of the Prakash Framework. While the court in Prakash referred to “a single incident of the offences committed” at [129(a)], the court expressly cautioned against dissecting the offending conduct into discrete instances for individual sentencing. Specifically, the court stated at [33] – [34]:

• 33 … it is impractical, and in many cases, impossible for the Court to determine the notional sentence that would have been imposed, had the offender been separately charged for each incident of offending. …

34 … it would be meaningless to approximate the sentencing outcome that would have been arrived if the offender had been separately charged for each incident of offending, as the sentencing outcome may be affected by entirely fortuitous events. Even if the offender was separately charged for each incident, the Prosecution may not necessarily proceed with all of the charges at a single trial.

23. I would further observe that expediency represents a key rationale for charge amalgamation, dispensing with the procedural burden of framing individual charges and providing corresponding particulars for each instance of offending. To require the Prosecution to nonetheless furnish such particulars for notional individual sentencing would defeat this very purpose. The Defence’s proposed approach of adopting the “average amount deceived” per incident is similarly misconceived, as this figure does not correspond to the subject matter of the amalgamated charge before the court.

24. Indeed, on the facts of the cases before the court in Prakash, the court did not express the appropriate sentence for a discrete instance of the offending conduct. Instead, the court assessed the offending conduct holistically, focusing on the number of instances of offending and the total amount of losses for each course of offending in each amalgamated charge (see for instance, Prakash at [67], [101] and [123]).

25. In my view, the proper approach at the first stage of the Prakash Framework is to treat the entire offending conduct as constituting a single criminal episode and determine the base sentence on that...
