How do the courts decide the sentence?
There is no single framework for cheating
Unlike some other offences, cheating under sections 417 and 420 of the Penal Code 1871 (“PC”) has no single sentencing framework laid down by the High Court for all cases. The courts instead proceed as follows:
- Comparable precedents. Sentencing is guided by earlier decisions, whose weight depends on how closely their facts correspond to the case at hand. Precedents decided without written reasons carry little weight.
- First principles. Where the precedents give no reliable guidance, the court reasons from first principles, assessing the harm caused and the offender’s culpability (blameworthiness), and then the factors personal to the offender.
The value of the property, and its limits
The value of the property obtained is often the primary yardstick, because it reflects both the benefit to the offender and the harm to the victim. The High Court has, however, identified two qualifications (in a 2019 decision on a corruption offence, Gan Chai Bee Anne v Public Prosecutor [2019] 4 SLR 838, in terms that apply generally): (1) value may not be a good measure of the offender’s culpability where the offender was not the person intended to benefit from what the victim parted with; and (2) value measures only the economic harm, not any wider harm to the public interest.
Factors that increase the sentence
Factors going to harm and culpability that have increased sentences for cheating in the decided cases include:
- the amount obtained and the loss caused, particularly where nothing has been repaid;
- misuse of a financial instrument or payment system on which commerce relies, such as cheques, credit cards or PayNow, where general deterrence (deterring others from similar offending) takes centre stage;
- planning and premeditation, including the use of false invoices, fictitious contracts or other false documents;
- abuse of trust or position, for example by an employee diverting payments meant for the employer, or a procurement officer concealing an interest in a vendor;
- a major or active role in the scheme;
- the number of victims and their vulnerability;
- obtaining public funds, such as government grants;
- persistence: offending over a long period, or in many separate transactions;
- harm beyond the immediate victim, such as harm to Singapore’s standing as a financial centre.
Aggravating features (i.e., factors that make an offence more serious) must, however, have a factual basis. In a 2026 trade-financing case (Lim Oon Kuin v Public Prosecutor and another matter [2026] 3 SLR 616), the offender’s company was a major oil trading company, and the District Court had treated the fraud as having harmed confidence in the oil trading industry as well as Singapore’s financial services sector when deciding the sentence. On appeal, the High Court accepted the harm to the financial services sector, but found that there was no factual basis for treating the fraud as having harmed the oil trading industry, and reduced the sentence accordingly.
Amalgamated charges: the three-step approach
The leading decision on amalgamated charges is Prakash s/o Mathivanan v Public Prosecutor [2025] 4 SLR 1386, in which the High Court set out the approach to sentencing an offender on an amalgamated charge under section 124(4) of the Criminal Procedure Code 2010 (“CPC”). It applies to amalgamated charges generally, including amalgamated charges of cheating, but it does not set ranges for cheating as such. The court proceeds in three steps:
- Step 1: the court identifies the punishment prescribed, and any sentencing guidance, for a single incident of the offence.
- Step 2: it sets a starting point by a holistic assessment of the whole course of conduct, including how long it lasted and how often the offences were committed.
- Step 3: it adjusts the starting point for factors personal to the offender, including any plea of guilty.
How have the courts applied these principles?
The table below summarises how the courts have applied these principles in some of the decided cases.
| Type of case | What happened | The takeaway |
|---|---|---|
| Small, single deceptions | In a 2013 decision (Idya Nurhazlyn bte Ahmad Khir v Public Prosecutor and another appeal [2014] 1 SLR 756), a first offender who had cheated her aunt of $1,800, and repaid it in full, received one month’s imprisonment; a further charge of paying $10,509 with a cheque that was dishonoured, while she was already under investigation, attracted three months. | A first offence is not automatically dealt with by a fine. The High Court indicated that a custodial sentence (i.e., imprisonment) will generally be appropriate where the victim parted with property of more than negligible value, and that the misuse of cheques calls for deterrence. |
| An employee diverting payments | In a 2026 District Court case (Public Prosecutor v Chai Song Lin [2026] SGDC 4), an assistant manager at a domestic worker agency changed the display name of his own PayNow account to resemble his employer’s name and gave clients QR codes linked to it, diverting $92,508 in 72 transactions over five months. Applying Prakash to an amalgamated charge under section 420 of the PC, the court took into account the amount, the planning, the abuse of his employer’s trust and the misuse of a payment system, and imposed 20 months and two weeks’ imprisonment after his early plea of guilty. | The misuse of a payment system on which the public relies is treated seriously, and the persistence of the offending over many transactions increases the sentence. |
| Obtaining government grants through a company | In a 2024 District Court case (Public Prosecutor v Tan Chee Boon [2026] SLR(StC) 120), a managing director used false invoices to obtain $246,400 in government grants for his company. He played a major and active role, the offending was planned, the sum was significant and no restitution (i.e., repayment to the victim) was made. The court gave little weight to the argument that the money had not gone directly into his pocket, as he benefited indirectly through the company, and imposed a global sentence of 40 months’ imprisonment. His plea of guilty, entered only on the first day of trial, carried little weight, and his appeal against the sentence was dismissed. | Where public funds are obtained through a company, the director’s role and the planning involved weigh heavily, and an indirect benefit is still a benefit. |
| Concealing a personal interest | In a 2023 District Court case (Public Prosecutor v Hussain Naina Mohamed [2023] SGDC 76), a procurement officer concealed his partnership in a vendor over about ten years, making at least $500,000 in secret profits. The court rejected a submission that a fine alone was sufficient and imposed a global sentence (i.e., the total sentence for all the charges) of 30 months’ imprisonment on ten charges (nine amalgamated charges of cheating or abetting cheating, and one amalgamated money laundering charge). | Concealment over a long period, with substantial secret profits, takes a case well beyond a fine. |
| A large commercial fraud | In Lim Oon Kuin, the founder and managing director of a major oil trading company was convicted after trial of two charges of cheating a bank into disbursing about US$56.1 million and US$55.8 million against fictitious sale contracts, and one charge of abetting (i.e., instigating, conspiring in and/or intentionally aiding) the forgery of a contract for the purpose of cheating. The District Court imposed eight years and six months on each cheating charge and nine years on the forgery charge, with two of the terms running consecutively: 17 years and six months in total. On appeal, the High Court upheld the convictions but reduced each sentence: it removed the aggravating weight given to harm to the oil trading industry, for which there was no factual basis; it gave substantially more credit for restitution that had almost halved the bank’s loss on the first charge; and it gave more weight to his old age. It refused to exercise “judicial mercy” (i.e., an exceptional power to reduce a sentence on compassionate grounds), because the offender’s ill health did not make his case truly exceptional. The sentences became six years, six years and seven years and six months, for a total of 13 years and six months’ imprisonment. | Even at the highest end, restitution and the offender’s age can make a substantial difference, and every aggravating factor must be supported by the facts. |
What is the sentencing range at a glance?
The table below gives the range of sentences seen in the cases reviewed, and the main factors that determined where each case fell. Every case turns on its own facts, and the figures are a guide only.
| Offence | Sentences seen in decided cases | Main deciding factors |
|---|---|---|
| Cheating (s 417), single charge | About 1 to 8 months’ imprisonment | The amount lost; whether it was repaid; whether the offender had offended before; misuse of cheques |
| Cheating (s 417), amalgamated charge | About 8 months on a single amalgamated charge; where there were nine amalgamated charges, 4 to 14 months per charge and 30 months in total | The number of incidents and how long they went on; the total amount and profit; any mental condition that contributed to the offending |
| Cheating and inducing delivery of property (s 420) | About 20 to 40 months for frauds of tens or hundreds of thousands of dollars; several years per charge for frauds of tens of millions of dollars | The amount; planning and the use of false documents; abuse of trust; whether public funds were involved; restitution; the timing of any plea of guilty; the offender’s age |
| Cheating by remote communication (s 420(2)) (offences from 30 Dec 2025) | No reported decision as at the date of this article | Imprisonment and at least 6 strokes of the cane are mandatory |
| Membership of an organised criminal group (section 5 of the Organised Crime Act 2015) | About 26 months, with a fine of $11,000 (one District Court case, 2025) | The offender’s role in the group, and the profit made |
Can the sentence be a fine?
A fine may be imposed as the only punishment under section 417 of the PC, but not under section 420, where imprisonment is mandatory and a fine may only be added to it.
Whether a fine alone is appropriate for cheating under section 417 of the PC depends on the facts of each case. The courts have recognised that it may be appropriate in some cases, for example:
- Where no loss was suffered. The High Court observed in the 2013 decision in the table above (Idya Nurhazlyn bte Ahmad Khir v Public Prosecutor and another appeal [2014] 1 SLR 756) that not every case of cheating causes loss, and that where no loss was ever suffered, a fine might be appropriate.
- Deceptions in share applications. In an earlier decision (Lim Choon Kang v Public Prosecutor [1993] 3 SLR(R) 254) concerning the deception of a company through share applications, the court observed that fines could be imposed in such cases unless the operation was of a substantial scale. In that case itself, three weeks’ imprisonment and a fine of $10,000 were upheld.
In other cases, the courts have imposed imprisonment, for example where the victim parted with property of more than negligible value (see the 2013 decision in the table above), or where at least $500,000 of secret profits had been made over about ten years (see the 2023 procurement case in the table above). Matters such as the amount involved, whether the victim suffered any loss, whether restitution was made and the offender’s record will all bear on whether a fine alone may be appropriate, and this is often a central question in submissions on sentence.
Fines are also imposed in addition to imprisonment, commonly to take back the offender’s profit. In a 2025 District Court case concerning an organised criminal group (Public Prosecutor v Tan Shay Howe [2025] SGDC 239), the offender’s profit of $11,000 was taken back by a fine of the same amount, imposed on the organised crime charge in addition to imprisonment. The fine stood when the High Court later increased his sentences on the related money laundering charges (Public Prosecutor v Tan Shay Howe [2026] 3 SLR 1304).
