Public Prosecutor v Ong Eng Siew

Ong Eng Siew, a 64-year-old man, pleaded guilty in the General Division of the High Court (Criminal Case No 42 of 2024) to one charge of attempted murder under s 307(1) of the Penal Code and one charge of voluntarily causing hurt (VCH) under s 323. Three further charges were taken into consideration: one of obstructing justice under s 204A(b) by disposing of the knife, and two VCH charges against the same woman, Berlin, from 1 June 2021.

According to the admitted statement of facts, Berlin, his former lover, had ended their relationship and begun one with Ku. The accused pestered her, assaulted her on 1 June 2021, and later sent her a photograph of a knife with a threat. On 12 June 2021, after drinking beer from 12pm to 8pm, he went to the void deck of Block 407 Choa Chu Kang Avenue 3 carrying a knife with a 12cm blade. When Berlin and Ku arrived he punched Ku, slashed his shoulder and, after Ku tripped and fell onto the grass, stabbed his chest and slashed his stomach. The chest wound lacerated Ku's left ventricle and, per the HSA report, would have been fatal without emergency treatment. When Berlin pulled at his shirt he pushed her into a drain and punched her. He fled, threw the knife into a drain and was arrested. He had been diagnosed with adjustment disorder (AD); the experts disagreed on its link to the offences, and a Newton hearing was held.

1. Whether the accused's adjustment disorder had a contributory link to the attempted murder and how much mitigating weight it deserved
2. What sentence was appropriate for the attempted murder charge and whether the Guidelines on Reduction in Sentences for Guilty Pleas applied to a plea indicated before they took effect
3. Whether the attempted murder and VCH sentences should run consecutively
4. Whether a compensation order should be made for Ku's medical expenses

Harm was severe: the injuries were life-threatening, required two surgeries, and the attack in a public place caused alarm. Aggravating factors were the continued attack on Ku while he lay on the ground, the taken-into-consideration charge of disposing of the knife, and self-induced intoxication. The court rejected the defence suggestion that a "scuffle" lessened culpability, describing the accused as the aggressor throughout, and did not treat the threats to Berlin as aggravating the attack on Ku. It found no premeditation, which was a neutral factor.

On the AD, the court preferred the defence psychiatrist, Dr Rajesh, whose view that the AD was a major contributory factor it found logical and evidence-based, and found the Prosecution expert's evidence confused. But because the AD was temporary and situational and the accused knew what he was doing was wrong, it reduced his culpability only to a limited extent, and general deterrence and retribution remained important. A low risk of reoffending and the voluntary $2,000 paid to Ku also counted in mitigation.

The court set an indicative starting sentence of 17 years on a claim-trial basis. It held the guilty-plea guidelines applied even though they came into effect on 1 October 2023: they built on existing principles that earlier pleas earn larger reductions. The plea fell in Stage 2, carrying a maximum 20% reduction; the court refused the Prosecution's request for only 15% as double-counting, and arrived at 13 years and seven months. For the VCH charge, applying the Niranjan framework, it raised a three-week starting point to five weeks for moderate culpability and reduced it to one month for the plea.

The sentences ran consecutively because the offences harmed two different victims and so violated distinct legally protected interests, and the aggregate was not crushing. A compensation order was refused because Ku was not shown to be impecunious, a civil claim was not shown to be inadequate, his own out-of-pocket expense was $210.25, and the MediSave and MediShield Life reimbursement rules only bite once a compensation order is made.

The court sentenced the accused to 13 years and seven months' imprisonment for attempted murder and one month's imprisonment for the VCH charge, to run consecutively, for an aggregate of 13 years and eight months' imprisonment backdated to his arrest on 12 June 2021. He could not be caned because of his age, and no extra imprisonment in lieu of caning was imposed. The court declined to make the compensation order the Prosecution sought.
