Public Prosecutor v Muhammad Isnalli David

Muhammad Isnalli David, a 22-year-old Singaporean, pleaded guilty in Criminal Case No 25 of 2025 to one charge of penile-vaginal rape under s 375(1)(a) of the Penal Code 1871. He consented to three further charges being taken into consideration for sentencing: criminal trespass, sexual assault by penetration with a finger, and a second rape charge. These are grounds of decision issued after he appealed against the sentence.

On the admitted statement of facts, on 27 March 2022 the victim, then 16, met a friend and the accused, who was 19, for a movie, and the group later drank gin at Admiralty Park with others, including two other men, Raden and Al'Amin. The victim became intoxicated and needed to vomit. The accused helped her to the female toilet, pulled her into a cubicle, locked the door and penetrated her without her consent. Raden and Al'Amin entered the toilet and saw this, and a video was taken. The two men then committed sexual penetrative acts on the victim in the cubicle, after which the accused penetrated her again. The victim muttered "don't" and "no" in Malay several times. The accused knew she was intoxicated and did not use a condom. At the time he was under a Reformative Training supervision order and on e-tagging, having earlier been convicted of rioting, impersonating a public servant and theft. Al'Amin pleaded guilty to a separate charge, while Raden claimed trial.

The Prosecution sought 12 to 13 years' imprisonment and 12 strokes of the cane; the Defence sought seven years and not more than four strokes.

1. Whether rehabilitation remained a dominant sentencing consideration given the accused's youth
2. Whether the offence should be treated as a group or multiple assault for the purposes of the Terence Ng framework
3. Where the offence fell within the Terence Ng sentencing bands and how offender-specific factors adjusted the sentence

The parties agreed, and the court accepted, that under Public Prosecutor v Koh Wen Jie Boaz [2016] 1 SLR 334 rehabilitation can be eclipsed by deterrence and retribution where the offence is serious or the harm severe. Here retribution and deterrence were dominant. The court said arguments that relied heavily on the accused's youth were misplaced, as youth cannot lessen the need to punish rape of this nature severely in the absence of exceptional circumstances.

The court rejected the Defence argument that there was no group rape because the accused had been alone with the victim at first. It described the events as an opportunistic successive assault by the three men. The accused's rape created the opportunity for the others, and starting the attack did not reduce his culpability. Relying on Public Prosecutor v CPS [2024] 2 SLR 749, the court held that group offending, even unplanned, is more serious, and this factor called for a substantial uplift.

Two further aggravating factors were present: the victim's intoxication, which the accused knew of and exploited when he offered to help her, whether or not she had been pressed to drink; and his failure to use a condom. The harm to the victim was already reflected in the framework's bands. The starting point was therefore in the middle to higher end of Band Two, about 15 years' imprisonment and 12 strokes. The plea of guilt attracted a 20% discount under the Sentencing Advisory Panel's guidelines, but this was weighed against his antecedents, his intoxication and the three charges taken into consideration, and the sentence was adjusted slightly downwards.

The court sentenced the accused to 12.5 years' imprisonment and caning, with the imprisonment term backdated to 20 November 2022, the date he completed his Reformative Training recall period while in remand.
