Public Prosecutor v Yoong Kok Kai

Yoong Kok Kai pleaded guilty to a charge of dangerous driving causing grievous hurt as a serious offender under s 64(2A)(a) and s 64(2A)(c) of the Road Traffic Act 1961 (2020 Rev Ed), which the court called intoxicated dangerous driving, and to a drink driving charge under s 67. A speeding charge was taken into consideration.

He had drunk whiskey and beer on three occasions the night before the crash and set out to drive from South Bridge Road to his home in Yishun. He instead drove west at great speed, reaching 134 km/h at one point and lane splitting, until he reached Tuas Checkpoint. There he rounded a bend, veered and crashed into an officer on duty, who had taken cover on the pavement behind a gantry post and a safety bollard. The officer suffered traumatic brain injuries and fractures, and is now bed-bound and non-communicative. A blood test showed 153 mg of alcohol in 100 ml of blood. No compensation had been paid, and public property was badly damaged.

The District Judge imposed three years and six months' imprisonment and 10 years' disqualification, applying the full 30% guilty plea reduction; the mandatory fine had been left out by oversight. The prosecution appealed against sentence in Magistrate's Appeal No 9042 of 2025.

1. Whether the prosecution's change of position on the guilty plea reduction affected the appeal
2. Whether the starting point for the intoxicated dangerous driving charge should be the maximum six years' imprisonment
3. Whether the full 30% reduction for the plea of guilt should be given in such egregious circumstances

On the change of position, the court said the final sentencing decision belongs to the court. It did not matter whether the prosecution had shifted ground; the court would have interfered with the plea reduction anyway. At the first hearing it had found incoherent the prosecution's stance that the offence was among the most egregious while still accepting a full 30% reduction, and it invited further submissions.

On the starting point, the court declined to lay down a sentencing framework but found this an egregious case. The respondent had driven a long distance while intoxicated, exposing others to great risk; that nothing happened before Tuas gave him no benefit. He drove very fast and in a manner the photographs and video showed to be extremely dangerous, and he struck a pedestrian standing on the pavement behind two barriers. The starting point should be the top of the range, six years, and the District Judge erred in starting lower. General deterrence alone would justify that starting point for those who drink heavily and then drive.

On the plea reduction, the court held that the 30% guideline is not fixed and can be displaced through the public interest exception noted in Jeremiah Ng, an earlier intoxicated dangerous driving case involving a death. The facts were at least comparable to that case, which involved a different limb of s 64 with a higher maximum. Someone who goes over a kerb at high speed while intoxicated cannot claim a full reduction, even if this leads to fewer guilty pleas. Given the overwhelming evidence, a 15% reduction sufficed. Applied to six years, this gave five years and one month, which the court rounded down to five years. The fine, not disputed, was imposed and the disqualification left unchanged.

The High Court allowed the prosecution's appeal. The sentence below was substituted with five years' imprisonment, a fine of $10,000 (in default, one month) and 10 years' disqualification.
