Summary
This High Court decision concerned three related criminal motions seeking extensions of time to file notices of appeal against sentence. The applicants—Tan Ki Peng, Ng Woei Koon, and Ang Boon Kian—had been sentenced by a District Judge to 34 months’ imprisonment for offences under the Customs Act involving the evasion of excise duty and GST. Their principal complaint was narrow: their imprisonment terms were backdated to the date of remand, whereas a co-accused’s sentence had been backdated to the date of arrest, resulting in an effective difference of two days.
The court dismissed all three motions. While the court accepted that the applicants were effectively seeking only a “very fine adjustment” (two days) to their custodial start dates, it held that there was no substantial injustice. The sentencing discretion to backdate imprisonment terms was not shown to have been exercised on a fundamental misapprehension of law, and the difference sought was too insignificant in the context of the overall 34-month sentence to justify appellate intervention, particularly given the delay in bringing the applications.
What Were the Facts of This Case?
On 8 April 2021, the three applicants were arrested together with a co-accused, Ching Jia Sheng (“Ching”). The arrests arose from their involvement in loading into a truck 1,585kg of cigarettes for which duty was not paid. The case therefore fell within the Customs Act framework governing excise duty and related fiscal offences.
On 20 August 2021, each applicant pleaded guilty to one charge under the Customs Act for evasion of excise duty amounting to $732,732. In addition, each applicant admitted a GST charge under the same Act for evasion of GST amounting to $58,786.73, and consented to the GST charge being taken into consideration for sentencing. The three applicants were represented by the same defence counsel throughout the District Court proceedings.
In a joint written mitigation plea dated 18 April 2021, defence counsel urged the District Judge to impose an imprisonment term of not more than 32 months, backdated to 10 April 2021, described as the date of remand. On 20 August 2021, the District Judge sentenced each applicant to 34 months’ imprisonment with effect from 10 April 2021. Thus, the custodial start date for each applicant was the date of remand rather than the date of arrest.
Subsequently, on 6 April 2022, Ching pleaded guilty before another District Judge to the same excise duty charge and consented to having the GST charge taken into consideration. Ching was also sentenced to 34 months’ imprisonment, but his sentence was backdated to 8 April 2021, the date of arrest (which was two days earlier than the date of remand). The applicants later sought to align their custodial start dates with Ching’s.
What Were the Key Legal Issues?
The first legal issue was procedural: whether the applicants should be granted an extension of time to file notices of appeal against sentence. The applications were filed on 24 August 2022, approximately 11 months after the District Judge’s sentencing on 20 August 2021. The court therefore had to consider the applicable threshold for granting extensions of time where the delay is substantial and where the surrounding circumstances suggest the applicants did not intend to challenge the decision at first instance.
The second issue was substantive but tightly bounded: whether the District Judge’s decision to backdate the imprisonment terms to the date of remand (rather than the date of arrest) amounted to an error justifying appellate intervention. The applicants did not seek to challenge the length of the sentence itself; they accepted the 34-month term. Their complaint was limited to an effective two-day difference in when their imprisonment would commence.
Underlying both issues was the sentencing principle governing backdating of custodial terms. The court had to assess how the discretion to backdate should be exercised, particularly in light of Court of Appeal guidance in BWM v PP, and whether any misapprehension of law or substantial injustice had occurred.
How Did the Court Analyse the Issues?
The court began by clarifying the scope of the applicants’ complaint. At the hearing, the applicants acknowledged that they had been represented jointly by defence counsel in the District Court. They explained that they had meant to state that they did not have defence counsel for the present motions. Importantly, they confirmed that they were not seeking to appeal against the 34-month imprisonment terms themselves. Their request was instead for an extension of time to appeal so that their imprisonment terms would commence on the date of arrest rather than the date of remand.
On the procedural question of delay, the court examined what the applicants said about when they learned of Ching’s sentence being backdated to the date of arrest. In their affidavits filed on 24 August 2022, they stated that they found out about it “recently” but did not specify when that “recent” knowledge began. The court nonetheless proceeded on the basis that they filed their applications soon after discovering the backdating difference, because the applications were filed about four and a half months after Ching was sentenced on 6 April 2022.
Even so, the court’s analysis focused on whether the applicants could meet the higher threshold for extensions of time where the delay is inordinate and where the circumstances indicate that the applicants did not intend to challenge the sentence at first instance. The prosecution relied on the Court of Appeal’s approach in Adeeb Ahmed Khan s/o Iqbal Ahmed Khan v PP [2022] SGCA 61, which emphasises that where delay and surrounding circumstances suggest an applicant did not intend to challenge the decision initially, the applicant must demonstrate substantial injustice. In particular, the injustice must arise from a fundamental misapprehension of law in the earlier decision and must be significant enough to have a bearing on the sentence imposed.
Turning to the merits, the court held that the District Judge’s backdating to the date of remand was consistent with the applicants’ own former defence counsel’s request in the joint written mitigation plea. The court therefore treated the District Judge’s approach as aligned with the submissions made at sentencing. The court also recognised that the Court of Appeal’s decision in BWM v PP had discouraged backdating to the date of remand in the absence of special reasons, favouring backdating to the date of arrest where the accused remains in custody after arrest.
However, the court did not treat the District Judge’s decision as illegal or as necessarily reflecting a misapprehension of law. The court reasoned that BWM v PP was decided only two days before the joint written mitigation plea was filed and four days before the District Judge sentenced the applicants. It was therefore plausible that neither defence counsel nor the District Judge was aware of BWM v PP at the time. Critically, the court stated that backdating to the date of remand was not illegal. If it had been illegal, the court indicated it would have exercised revisionary power to correct the sentences.
In assessing whether there was substantial injustice, the court placed significant weight on the “very fine adjustment” nature of the requested change. The court noted that BWM v PP involved a one-day difference and that the Court of Appeal declined to make the “very fine adjustment in favour of the appellant” in light of the entire situation, including that the issue of backdating was not raised on appeal. By analogy, the applicants here were seeking a two-day adjustment. The court held that such a difference was marginal and did not warrant appellate intervention, especially considering the overall length of the custodial term.
The court also addressed the applicants’ belief that the two-day difference would “mean a lot” to them and their families, citing financial and health issues. While acknowledging that such considerations are humanly understandable, the court held that the difference must be evaluated in context. A two-day adjustment within a 34-month sentence was “really too insignificant” to justify an extension of time to appeal against a decision made on 20 August 2021.
Finally, the court concluded that there was clearly no substantial injustice in the circumstances. The District Judge’s backdating decision was not shown to have been based on a fundamental misapprehension of law, and the requested change did not meet the threshold required for an extension of time to appeal. Accordingly, the motions were dismissed.
What Was the Outcome?
The High Court dismissed Criminal Motions Nos 44, 45 and 46 of 2022. The practical effect was that the applicants were not granted extensions of time to file notices of appeal against sentence, and their sentences remained as originally imposed by the District Judge, with imprisonment commencing from the date of remand rather than the date of arrest.
Because the court dismissed the motions on both procedural and substantive grounds, the applicants did not obtain any adjustment to their custodial start dates. The decision therefore confirmed that, absent special reasons and absent substantial injustice, appellate courts will be reluctant to revisit the discretionary backdating of imprisonment terms—particularly where the requested adjustment is minimal and where the delay in seeking appellate review is significant.
Why Does This Case Matter?
Tan Ki Peng v Public Prosecutor and other matters is a useful authority for practitioners dealing with applications for extension of time to appeal against sentence in Singapore. It reinforces that where an applicant seeks to challenge a sentence long after it was imposed, the court will apply a heightened threshold. The applicant must show substantial injustice, typically linked to a fundamental misapprehension of law in the earlier decision, rather than relying on perceived unfairness or minor differences in sentencing mechanics.
Substantively, the case also illustrates how the Court of Appeal’s guidance in BWM v PP about backdating custodial terms will be applied in practice. While BWM v PP discourages backdating to the date of remand in the absence of special reasons, Tan Ki Peng demonstrates that a departure from that guidance does not automatically render the sentence illegal. Instead, the court will consider whether the sentencing judge’s approach was based on a misapprehension of law and whether any resulting injustice is substantial.
For defence counsel and accused persons, the decision underscores the importance of raising sentencing backdating issues promptly at the time of sentencing and, if necessary, on appeal. The court’s emphasis on the “very fine adjustment” and the insignificance of a two-day difference suggests that appellate intervention will be difficult to justify unless the error is material to the sentencing outcome or unless special reasons exist. Practitioners should therefore treat backdating as a matter requiring early attention—both in mitigation submissions and in the formulation of any appeal grounds.
