Public Prosecutor v Tan Shay Howe

Tan Shay Howe, a 48-year-old Singaporean, was part of an organised crime group that used SMS modems and pre-registered SIM cards to sell anonymous WhatsApp and WeChat accounts, paid for in cryptocurrency, to customers who used them to conceal their identities, including for scams. He invested in the business from October 2023, agreed between January and February 2024 to take it over from its founder Alvin, and from March 2024 let the group use office space above his son's motor workshop for S$3,000 a month. A raid on 29 May 2024 seized 24,000 pre-paid SIM cards, which were linked to 2,393 police reports.

He pleaded guilty in the District Court to a charge under the Organised Crime Act 2015 and two charges under s 54(1)(c) of the CDSA of conspiring to acquire the group's benefits from criminal conduct: S$328,974.09 (November 2023 to January 2024) and S$449,962.90 (March 2024 to May 2024). Drawing on Juandi and the ranges in Ho Man Yuk, the district judge imposed 15 and 16 months on those charges, for an aggregate of 42 months and two weeks with a fine of S$11,000. The Prosecution appealed in Magistrate's Appeal No 9127 of 2025/01 against the two CDSA sentences only.

1. Whether a sentencing framework should be adopted for self-laundering offences under s 54(1) of the CDSA
2. Whether the Huang Ying-Chun framework should be modified when applied to such offences
3. Whether the sentences for the CDSA charges were manifestly inadequate on a proper assessment of the respondent's role

The court noted that two inconsistent methods had been used for s 54(1) offences. The ranges in Ho Man Yuk served internal consistency within that case and are not a general benchmark. Given the expected rise in scam-related laundering and the many ways the offence can be committed, the court adopted the five-step harm-culpability framework in Huang Ying-Chun, because ss 51(1)(a) and 54(1) involve the same criminality and carry the same maximum punishment.

The court rejected the young independent counsel's proposed fixed 10% uplift to reflect a self-launderer's knowledge, leaving any uplift to case-by-case calibration, since Parliament set the same maximum and no basis supported that figure. It accepted the vulnerability of victims, including elderly persons, as a harm factor, while warning against counting it twice where it already informs the seriousness of the predicate offence.

Harm was moderate for both charges, given the sums, the serious scam-related predicate offence, the syndicate and the transnational element. The district judge had understated the respondent's role. Confined to the agreed facts, he was a financier during the first charge but a key member from February 2024, though not a leader in the way Alvin had been, so his culpability was low for the first charge and medium for the second. Starting points of 30 and 36 months, a one-month uplift for the charges taken into consideration and a 30% discount for his early plea produced 22 and 26 months. These terms were consistent with Lim Seng Soon and Kandasamy, and the aggregate was commensurate with his criminality and the need to deter the facilitation of scams.

The High Court allowed the Prosecution's appeal and enhanced the sentences to 22 months' imprisonment for the first CDSA charge and 26 months for the second. With the sentence for the organised crime charge unchanged, the aggregate became 52 months and two weeks, and the S$11,000 fine stood.
