Summary
In Muhammad Rahmat bin Abu Bakar v Public Prosecutor ([2022] SGHC 118), the High Court considered whether the sentencing parity principle was breached when a District Judge imposed a higher imprisonment term on the appellant than on his co-accused for the same offence arising from the same prison incident. Both the appellant and Noor Awwalludeen bin Jamil were charged under s 325 read with s 34 of the Penal Code for voluntarily causing grievous hurt in furtherance of a common intention. The victim suffered severe injuries, including skull, facial and rib fractures, and required emergency surgery.
The appellant pleaded guilty to the same VCGH offence as his co-accused. Yet, while the co-accused received 4 years and 6 months’ imprisonment (with six strokes of the cane), the appellant received 6 years’ imprisonment (with six strokes of the cane). The appellant appealed only the imprisonment term, arguing that parity required the same custodial sentence as that imposed on the co-accused. The High Court accepted the argument, holding that the differences relied on by the District Judge were not sufficiently relevant or justified, and substituted a sentence of 4 years and 6 months’ imprisonment with six strokes of the cane.
What Were the Facts of This Case?
The incident occurred in Changi Prison Complex. The appellant and the co-accused, both inmates, had a dispute with the victim concerning noise generated in their cells on some nights. Tensions escalated, and the appellant and co-accused decided that they would beat up the victim when they had the opportunity.
On the morning of 17 September 2020, the victim, the appellant and the co-accused were brought to a waiting room at the medical centre for medical reviews. During this encounter, the appellant and co-accused signalled to each other. They then proceeded to punch, kick and stamp on the victim until the victim lay unconscious on the ground.
The injuries were severe and extensive. The victim suffered skull, facial and rib fractures and required emergency surgery, followed by various forms of therapy. The prosecution charged both the appellant and co-accused with an offence punishable under s 325 read with s 34 of the Penal Code, reflecting that the grievous hurt was caused voluntarily and in furtherance of a common intention.
At sentencing, the co-accused pleaded guilty to the VCGH offence and was sentenced to 4 years and 6 months’ imprisonment and six strokes of the cane. The prosecution initially filed an appeal against the co-accused’s VCGH sentence but later discontinued it after the co-accused discontinued his own appeal against the total sentence. The appellant, who also pleaded guilty to the same VCGH offence, was sentenced to a higher imprisonment term of 6 years (with six strokes of the cane). The appeal before the High Court focused on whether this custodial disparity violated the parity principle.
What Were the Key Legal Issues?
The primary legal issue was the applicability and operation of the sentencing parity principle in the context of co-offenders who participated in the same incident. The High Court had to determine whether the appellant’s higher imprisonment term, compared with the co-accused’s sentence for the same offence, constituted a serious disparity without relevant justification.
A secondary issue concerned how parity should be assessed within the structured sentencing framework for s 325 offences. The court needed to consider the two-step sentencing approach: first, determining an indicative starting point based on the seriousness of the injury; and second, adjusting that starting point based on the offender’s culpability and the presence of aggravating or mitigating factors. The question was whether the District Judge’s calibration properly identified relevant differences between the appellant and co-accused, or whether it relied on factors that could not justify the observed disparity.
How Did the Court Analyse the Issues?
The High Court began by reaffirming the classical statement of the parity principle in Public Prosecutor v Ramlee and another action [1998] 3 SLR(R) 95. In essence, where two or more offenders are sentenced for participation in the same offence, their sentences should be the same unless there is a relevant difference in responsibility or personal circumstances. A ground of appeal arises where one offender receives a significantly more severe sentence than an accomplice and there is no reason for differentiation, provided the disparity is serious.
The court also referred to the expanded understanding of parity in Public Prosecutor v Ng Sae Kiat and other appeals [2015] 5 SLR 167, where the parity principle is not confined to situations where co-offenders were charged with the same offence arising from the same transaction or events. Instead, it can apply where offenders are, as a matter of substance, participants in a common criminal enterprise. However, the High Court emphasised that the present case fell squarely within the “classic” parity scenario: the appellant and co-accused were involved in the same incident and were charged for the same offence arising from the same harm.
On that basis, the High Court adopted a practical approach. It stated that the correct method is to first determine the appropriate sentence for the appellant. If the sentence is comparable to the co-accused’s sentence, no parity infringement arises. If there are differences, the court must examine whether those differences are justified by relevant factors affecting culpability or personal circumstances.
Turning to the sentencing framework, the parties did not dispute that the District Judge should have applied the two-step approach for s 325 offences as set out in Public Prosecutor v BDB [2018] 1 SLR 127. The first stage requires an indicative starting point based on the seriousness of the injury. The second stage adjusts that starting point upwards or downwards based on culpability and aggravating or mitigating factors.
On the harm stage, the High Court found no meaningful basis to differentiate between the appellant and co-accused. The injuries caused to the victim were the same in substance, and there was no attribution of specific injuries to one or the other. Both were involved in the continuous attack, and both were charged under s 325 read with s 34 for acting in furtherance of a common intention. This meant that the indicative starting point should not be materially different on the basis of harm.
Nevertheless, the indicative starting points differed: the appellant’s indicative starting point was 4 years and 6 months’ imprisonment with six strokes of the cane, while the co-accused’s was 4 years and 3 months’ imprisonment with six strokes of the cane. The High Court considered the three-month difference to be relatively small. It noted that parity concerns require a “significant or serious difference” and that de minimis differences may not, by themselves, establish a parity infringement.
The real question was whether the District Judge’s subsequent calibration justified the larger disparity in the final imprisonment term. The District Judge had concluded that aggravating factors applicable to the appellant justified a substantial difference of one year and six months. The High Court scrutinised the factors relied upon: (i) the age difference between the appellant and co-accused, and (ii) differences in antecedent history.
On age, the High Court rejected the District Judge’s reasoning. The appellant was 20 years old (one month shy of turning 21) and the co-accused was 19. The High Court held that a one-year age gap could not justify a materially different outcome. While maturity may affect the degree of responsibility and moral culpability (as discussed in relation to s 83 of the Penal Code in Public Prosecutor v ASR [2019] 1 SLR 941), the court found that the mere one-year difference between a 20-year-old and a 19-year-old did not provide a relevant basis for a significant sentencing disparity.
On antecedents, the High Court took a more nuanced view. It found that the antecedent histories were largely similar. Although the co-accused had committed a string of other offences, the High Court did not accept that the antecedents were so different as to justify the substantial increase in the appellant’s custodial term. In other words, the factors relied upon did not amount to relevant differences in culpability or responsibility sufficient to explain the disparity.
The High Court also addressed the District Judge’s approach to “crystallisation” of antecedents. The District Judge had treated the appellant’s prior reformative training sentence as having “crystallised” as antecedents that would amplify culpability at the VCGH sentencing hearing. By contrast, the co-accused’s offences were dealt with together in a single sentencing hearing, so the District Judge considered that there was no crystallisation for the co-accused.
The High Court found this reasoning unhelpful. It explained that antecedents matter because they indicate greater culpability and responsibility due to continuing criminal behaviour or a pattern or tendency toward such behaviour. While some statutory provisions may specify forms of antecedents as preconditions for enhanced or special punishment, the court’s discretionary calibration should not be overly rigid in defining what counts as an antecedent. The exercise is fundamentally about assessing culpability and responsibility. Weighing whether a prior antecedent or type of punishment has “crystallised” does not assist that assessment.
Finally, the High Court considered an argument relating to the prosecution’s earlier discontinuance of its appeal against the co-accused’s sentence. The High Court held that the absence of an appeal or challenge to the adequacy of the co-accused’s sentence does not preclude the prosecution from attacking the appellant’s sentence as inappropriate. However, in the parity analysis, what matters is the direct comparison of punishment for the same offence imposed on one person versus another. The court suggested that global adequacy of the co-accused’s sentence is not determinative for parity; the parity principle turns on whether the differentiation is justified for the same offence and same harm.
What Was the Outcome?
The High Court allowed the appeal. Taking into account justifiable differences in responsibility for the same harm, it substituted the appellant’s imprisonment term with a sentence of 4 years and 6 months’ imprisonment and six strokes of the cane.
Practically, this brought the appellant’s custodial sentence into line with the co-accused’s sentence for the same VCGH offence arising from the same prison incident, thereby vindicating the parity principle where the sentencing disparity was not supported by relevant differences in culpability or personal circumstances.
Why Does This Case Matter?
This decision is a useful illustration of how the parity principle operates in Singapore sentencing practice, particularly in cases involving co-offenders who participated in the same incident. The High Court’s analysis reinforces that parity is not merely a matter of “same offence” in a formal sense; it requires a substantive comparison of responsibility and personal circumstances, and it demands justification for any serious disparity.
For practitioners, the case highlights several practical sentencing lessons. First, parity concerns require a “significant or serious” disparity; minor differences may not trigger appellate intervention. Second, when applying the two-step sentencing framework for s 325 offences, courts must ensure that any differences in the final sentence are anchored in relevant culpability or aggravating/mitigating factors, not in factors that are tenuous or irrelevant to moral culpability (such as an insignificant age gap).
Third, the court’s critique of the “crystallisation” concept is instructive. While antecedents are important, the assessment should focus on what antecedents actually indicate about continuing criminal behaviour or culpability. The decision cautions against overly mechanical reasoning based on procedural timing of sentencing or the labelling of antecedents as “crystallised” without a clear link to culpability.
