Public Prosecutor v Loh Cheok San

Loh Cheok San, a 51-year-old cargo officer at Vermont UM Bunkering Pte Ltd, pleaded guilty to two amalgamated charges of abetting cheating by conspiracy under s 420 read with s 109 of the Penal Code. Under the second charge, from 2014 to 2016 he took part with Vermont's management and the company itself in buyback transactions: vessel engineers or captains were paid to let Vermont supply less fuel than ordered, and the fuel bought back was resold. He participated in 52 such transactions, through which Vermont's customers were cheated of approximately USD$3,645,976, and earned a commission of at least $43,600. Under the first charge, he conspired with his bunker manager and another cargo officer to over-declare the price or quantity of fuel bought back, so that Vermont paid them more than was actually paid out; Vermont lost about USD$980,000, of which he gained approximately USD$314,961.

The District Judge sentenced him to 35 months' imprisonment on the first charge and 65 months' on the second, running concurrently. The judge treated the offences as inextricably related and declined to protect Vermont's interest, reasoning that Vermont was itself a conspirator. The Prosecution brought Magistrate's Appeal No 9210 of 2022/01 against the aggregate sentence, seeking a global term of 100 months by running the sentences consecutively.

1. Whether the one-transaction rule applied so that the sentences should run concurrently.
2. Whether Vermont's role as a co-conspirator justified not protecting its interest as victim of the first charge.
3. Whether the totality principle required the aggregate sentence to be adjusted.

The one-transaction rule turns on whether there was a single invasion of the same legally protected interest. The District Judge accepted that the interests were different, and factual links such as proximity in time and place, or one offence creating the opportunity for the other, are not enough. The two conspiracies involved different groups, different complexity, different objectives and different victims: a sophisticated scheme against customers, and a simpler one by employees against Vermont. Vermont was dishonestly induced to pay more and so was a victim of the first charge.

Relying on Rex v Tan Ah Seng and Raj Kumar s/o Brisa Besnath v Public Prosecutor [2021] SGCA 88, the court held that an offender should not escape punishment because the victim conspired with him in another crime; criminal law focuses on the offender's own conduct. Concurrent sentences would leave him with no real consequence for the second conspiracy. The late guilty plea, entered more than four years after he was charged, did not favour concurrency. Alternatively, even if the rule applied, departure was justified by his enhanced culpability.

On totality, the court rejected the argument that only precedents involving conspiracies were relevant and found the normal range for a comparable single cheating charge was between 33 and 39 months. A 100-month total was substantially above that range and disproportionate, so the second sentence was recalibrated to reach 80 months. That term was not crushing given his age, and the original 65 months was manifestly inadequate.

The High Court allowed the Prosecution's appeal in part. It reduced the sentence on the second charge from 65 to 45 months' imprisonment and ordered it to run consecutively with the 35-month sentence on the first charge, giving a global sentence of 80 months' imprisonment rather than the 100 months sought.
