Summary

This criminal motion concerned an attempt by the applicant, while his District Court trial was still ongoing, to obtain permission from the High Court under s 283 of the Criminal Procedure Code 2010 (2020 Rev Ed) to adduce further evidence in the form of oral testimony from a witness. The motion was framed as a request for the High Court to exercise powers over the ongoing trial, but the court held that the application was procedurally misconceived because the proper forum was the trial court hearing the substantive matter. (Paras 1, 15, 16, 18)

The applicant had been facing five cheating charges under s 420 of the Penal Code and one Companies Act charge in relation to an alleged scheme involving invoice financing facilities and the use of loan monies to assist in the purchase of shares. The trial had already progressed substantially: the Prosecution had closed its case, both defence cases had closed, and the District Judge had directed closing submissions. Against that background, the applicant sought to revive the issue of calling the witness, relying in part on an asserted change in circumstances involving travel restrictions in China. (Paras 2, 4, 5, 6, 10)

The High Court dismissed the motion on the procedural ground, declined to decide whether the witness’s testimony was “essential to making a just decision in the case,” and held that s 283 CPC is a power for the court hearing the substantive matter, not for a superior court to exercise mid-trial through original, appellate, or revisionary jurisdiction. The court also ordered the applicant to pay the Prosecution costs of $2,000, finding the motion frivolous and bound to fail. (Paras 15, 19, 25, 29, 30)

What Was the Applicant Trying to Achieve by Filing CM 30 in the High Court?

The motion was an application to the General Division of the High Court to exercise powers under s 283 CPC so that the applicant could adduce further evidence at the hearing of the District Court trial in the form of oral testimony from Mr Alexander Chua Hock Yew, referred to in the judgment as “the Witness.” The court described the application in terms that make clear the applicant was not seeking a final determination of the criminal charges, but rather an interlocutory order affecting the conduct of the ongoing trial. (Para 1)

"CM 30 was an application to the General Division of the High Court (“High Court”) “to exercise its powers under section 283 of the Criminal Procedure Code 2010 (2020 Rev Ed) (“CPC”) by granting the Applicant permission to adduce further evidence at the hearing of DAC 924315 to 942319 of 2018 in the form of oral testimony from Mr Alexander Chua Hock Yew” (“the Witness”)." — Per Tay Yong Kwang JCA, Para 1

The court’s description of the motion is important because it shows that the applicant was asking the High Court to intervene in the middle of a live trial, rather than waiting for the trial judge to decide whether the witness should be called. That procedural posture was central to the court’s analysis, because the court treated the application as one that sought to bypass the ordinary trial process. (Paras 1, 16, 18)

The applicant’s position was that the High Court could entertain the request directly, and that the meaning of “court” in s 283 CPC might extend beyond the trial court. The court rejected that premise, holding that the statutory language and structure pointed in the opposite direction. (Paras 9, 18, 29)

What Were the Underlying Charges and Why Did the Witness Matter?

The applicant was on trial for five cheating charges under s 420 of the Penal Code, said to arise from a scheme that caused three banks to extend loans to Jason Parquet Specialist (Singapore) Pte Ltd under invoice financing facilities between 7 September 2012 and 16 March 2015. He also faced one Companies Act charge under s 76(1)(a)(ii)(B), punishable under s 76(5) read with s 408(3)(b), concerning the use of loan monies to give financial assistance to Tjioe for the purchase of shares in JPH. These charges formed the substantive backdrop to the procedural dispute over whether the witness should be called. (Paras 2, 4)

"At the Trial, the applicant faced five charges under s 420 of the Penal Code (Cap 224, 2008 Rev Ed) (“Penal Code”) for perpetrating a scheme to cheat three banks – DBS Bank Ltd (“DBS”), Standard Chartered Bank (Singapore) Limited and Malayan Banking Berhad (together, “the banks”) – by causing them to extend loans to one Jason Parquet Specialist (Singapore) Pte Ltd (“JPS”) under invoice financing facilities between 7 September 2012 and 16 March 2015." — Per Tay Yong Kwang JCA, Para 2

"The applicant also faced one charge under s 76(1)(a)(ii)(B) punishable under s 76(5) read with s 408(3)(b) of the Companies Act (Cap 50, 2006 Rev Ed)." — Per Tay Yong Kwang JCA, Para 4

The extraction does not state in detail what the witness would have said, but it does show that the applicant considered the witness important enough to seek an order permitting oral testimony. The court, however, expressly declined to decide the substantive question whether the testimony was “essential to making a just decision in the case,” because that issue belonged to the trial court. (Paras 15, 19)

That refusal to engage with the merits is itself significant. The court’s reasoning was not that the witness was irrelevant, but that the High Court was not the proper forum to decide the issue at that stage. The procedural objection therefore controlled the outcome. (Paras 15, 18, 19)

How Did the Trial Reach the Stage Where CM 30 Was Filed?

The trial had already advanced substantially by the time CM 30 was filed. The Prosecution closed its case on 23 April 2021, and by 18 May 2022 both the applicant and Tjioe had closed their defence cases. The District Judge then directed the parties to file closing submissions. When CM 30 was filed on 15 June 2022, the District Judge stayed the trial indefinitely pending the outcome of the motion. (Para 5)

"The Trial began on 30 September 2020 and took place over 27 days. On 23 April 2021, the Prosecution closed its case. By 18 May 2022, both the applicant and Tjioe had closed their cases for the defence." — Per Tay Yong Kwang JCA, Para 5

That chronology mattered because it showed that the motion was not made at the outset of the trial, but after the evidential phase had largely run its course. The court treated this as reinforcing the impropriety of asking the High Court to step in directly, especially when the trial judge had not yet ruled on the new application in the changed circumstances asserted by the applicant. (Paras 5, 19, 20)

The court also noted that before CM 30 was filed, the applicant had already made several applications to the District Judge to have the witness give evidence at trial. The existence of those earlier attempts showed that the issue had been live in the proceedings and had already been ventilated at the trial level, which made the decision to bypass the trial judge even more difficult to justify. (Para 6)

"Before CM 30 was filed, the applicant made several applications to the DJ to for the Witness to give evidence at the Trial." — Per Tay Yong Kwang JCA, Para 6

What Arguments Did the Applicant Advance to Justify a Direct High Court Application?

The applicant’s counsel submitted that it was unclear whether the word “court” in s 283 CPC referred only to the trial court or also included the High Court. On that basis, counsel argued that it was open to the applicant to proceed by criminal motion and seek an order from the High Court directing the District Judge to allow the witness to be called. The applicant therefore attempted to cast the issue as one of statutory interpretation and procedural route. (Para 9)

"The applicant’s counsel submitted that it was unclear if the “court” in s 283 CPC referred only to the trial court or included the High Court. He believed that it was open to him to apply by way of criminal motion for an order from the High Court to direct the DJ to allow the Witness to be called at the Trial." — Per Tay Yong Kwang JCA, Para 9

The applicant also relied on an asserted material change in circumstances. Counsel submitted that the witness had previously been unable to travel to Singapore because of pandemic travel restrictions imposed in China, but that the restrictions were easing and the witness had agreed to come to Singapore. The applicant’s case was therefore that the factual landscape had changed sufficiently to justify revisiting the issue of the witness’s evidence. (Para 10)

"The applicant’s counsel also submitted that there was a material change in circumstances. Previously, the Witness was not able to travel to Singapore because of the pandemic travel restrictions imposed in China." — Per Tay Yong Kwang JCA, Para 10

The extraction also records that the applicant’s counsel drew an analogy with bail applications, suggesting that the High Court’s powers under the CPC could be invoked directly in a manner similar to other procedural applications. The court did not accept that analogy as a basis for bypassing the trial judge in the context of s 283. (Para 16)

In substance, the applicant’s position was that the High Court should intervene because the witness had become available and because the statutory language might permit such intervention. The court’s answer was that even if the witness had become available, the proper forum remained the trial court, and the High Court could not use its supervisory powers to short-circuit the trial process. (Paras 18, 19, 29)

Why Did the Prosecution Say CM 30 Was Procedurally Flawed?

The Prosecution submitted that the applicant appeared to be invoking the High Court’s revisionary jurisdiction in seeking an order summoning the witness. It argued that CM 30 was procedurally flawed because the applicant should have applied to the District Judge to summon the witness under s 283(1) CPC. The Prosecution’s position was therefore that the motion was not merely weak on the merits, but wrongly brought in the first place. (Para 12)

"The Prosecution submitted that the applicant appeared to be invoking the High Court’s revisionary jurisdiction in seeking an order summoning the Witness." — Per Tay Yong Kwang JCA, Para 12

"It submitted that CM 30 was procedurally flawed because the applicant should have applied to the DJ to summon the Witness under s 283(1) CPC." — Per Tay Yong Kwang JCA, Para 12

The court accepted that submission. It held that the structure of s 283 CPC showed that the power to summon, examine, recall, or re-examine witnesses belongs to the court hearing the substantive matter, and that the provision contemplates an application made in the ongoing proceedings to that court. The High Court therefore could not be the first-instance forum for such an application while the trial was still underway. (Paras 18, 29)

The Prosecution also argued that the motion was an abuse of process and substantively unnecessary, but the court did not need to decide the substantive necessity issue because the procedural defect was dispositive. The judgment is thus a clear example of a court resolving a motion on threshold jurisdictional and procedural grounds without reaching the merits. (Paras 12, 15, 29)

How Did the Court Interpret Section 283 CPC?

The court’s interpretation of s 283 CPC was the core of the judgment. It quoted the provision and emphasized that the power is exercised by “a court” at the close of the defence case or at the end of proceedings under the CPC. The court read that language as referring to the court conducting the substantive proceedings, not a superior court asked to intervene from outside the trial. (Paras 8, 18)

"Power of court to summon and examine persons 283.—(1) A court may, on its own motion or on the application of the prosecution or the defence, at the close of the case for the defence, or at the end of any proceeding under this Code, summon a person as a witness or examine a person in attendance as a witness, whether or not summoned, or recall and re‑examine a person already examined." — Per Tay Yong Kwang JCA, Para 8

The court stated that it was “plain” from the language of s 283(1) that the provision contemplates the tail end of a trial or other proceedings before a court of original jurisdiction, and that any application under the provision is made in the ongoing proceedings to that court. That reading was decisive because it meant the applicant’s direct resort to the High Court was inconsistent with the statutory scheme. (Para 18)

"Section 283(1) states that “[a] court may, on its own motion or on the application of the prosecution or the defence, at the close of the case for the defence, or at the end of any proceeding under this Code, summon a person as a witness or examine a person in attendance as a witness, whether or not summoned, or recall and re‑examine a person already examined.” It is plain from the language of s 283(1) that the provision contemplates the tail end of a trial or other proceedings before a court of original jurisdiction and that any application under the provision is made in the ongoing proceedings to that court." — Per Tay Yong Kwang JCA, Para 18

The court reinforced that interpretation by referring to authority stating that the predecessor provision, s 399 of the Criminal Procedure Code, was “for a trial judge” to exercise. That authority supported the proposition that the power is trial-centric and not designed for a superior court to exercise in the abstract while the trial is still live. (Para 18)

"This is reinforced by the Court of Appeal in Sim Cheng Hui and another v Public Prosecutor [1998] 1 SLR(R) 670 at [28],22 which stated that s 399 of the Criminal Procedure Code (Cap 68, 1985 Rev Ed), the predecessor of s 283 CPC, was “for a trial judge” to exercise." — Per Tay Yong Kwang JCA, Para 18

The court also made the broader point that s 283 does not contemplate an application to a higher court, whether by invoking appellate or revisionary jurisdiction, while the proceedings in the trial court are still ongoing. That statement captures the ratio of the case in direct terms. (Para 18)

"Clearly, s 283 does not contemplate an application being made to a higher court, whether by invoking its appellate or its revisionary jurisdiction, while the proceedings in the trial court are still going on." — Per Tay Yong Kwang JCA, Para 18

Why Did the Court Reject Appellate and Revisionary Jurisdiction as a Route Around the Trial Judge?

The court held that the applicant could not invoke the High Court’s original jurisdiction because that jurisdiction resided with the District Court, which was still hearing the ongoing trial. It also held that there was no basis for revisionary intervention because no decision had yet been made by the District Judge on the asserted changed circumstances, and therefore there was no error below and no material and serious injustice to correct. (Paras 19, 22)

"In this application, the applicant could not be invoking the High Court’s original jurisdiction as this resided with the District Court which is still hearing the ongoing Trial." — Per Tay Yong Kwang JCA, Para 19

The court quoted the revisionary jurisdiction test from Xu Yuanchen: there must first be some error in the decision or order made by the judge below, and second, material and serious injustice must have been occasioned as a result. Because the District Judge had not decided the new application based on the alleged change in circumstances, the first condition was absent. Without a decision below, there could be no revisionary complaint. (Para 19)

"revisionary jurisdiction may only be invoked when two conditions are fulfilled. First, there must be some error in the decision or order made by the judge below and second, material and serious injustice must have been occasioned as a result." — Per Tay Yong Kwang JCA, Para 19

The court further observed that, as the matter stood, there was no decision made by the District Judge and therefore there could not have been any material and serious injustice to complain of. That reasoning is important because it shows the court’s insistence on procedural sequence: the trial court must first act, and only then can a superior court consider whether its intervention is justified. (Para 19)

"As the matter stood, there was no decision made by the DJ and therefore there could not have been any material and serious injustice to complain of." — Per Tay Yong Kwang JCA, Para 19

The court also relied on the general principle that interlocutory appeals are not countenanced in criminal proceedings, save in exceptional circumstances. It quoted the proposition that, barring something “imminently fatal” to the applicant’s case, the law does not permit premature applications in the middle of trial. That principle was used to reject the applicant’s attempt to obtain mid-trial intervention from the High Court. (Para 20)

"Barring something ‘imminently fatal to the applicant’s case’ (Yap Keng Ho at [6]), the law does not countenance such premature applications in the middle of trial." — Per Tay Yong Kwang JCA, Para 20

What Authorities Did the Court Rely On to Explain Why Interlocutory Intervention Is Disfavoured?

The court referred to a line of authorities that collectively explain why criminal trials should not be fractured by interlocutory challenges. It cited Christanto Radius for the proposition that s 97 CPC is a statutory power of review over bail decisions, but distinguished that context from the present one. The point of the citation was to show that some statutory review powers exist, but that s 283 is not one of them in the way the applicant suggested. (Para 17)

"For instance, Choo Han Teck J in Christanto Radius v Public Prosecutor [2012] 3 SLR 749 at [6] referred to s 97 of the Criminal Procedure Code 2010 (Act 15 of 2010) as a “statutory power of review” over the District Judge’s decision in that case to refuse the grant of bail (see also s 93(3C) CPC)." — Per Tay Yong Kwang JCA, Para 17

The court then quoted from Xu Yuanchen, which in turn drew on Public Prosecutor v Hoo Chang Chwen, Yap Keng Ho, Azman bin Jamaludin, and Ng Chye Huey. The quoted passage explained that interlocutory appeals against rulings in criminal trials are generally prohibited because they would stifle the trial process, create fractured proceedings, and make it difficult to assess matters in “inchoate circumstances.” (Para 20)

"The law is clear that interlocutory appeals against rulings in criminal trials are generally prohibited. As the Court of Appeal stated in Public Prosecutor v Hoo Chang Chwen [1962] MLJ 284 at 285, “the effect of allowing appeals from interlocutory rulings would be to stifle the criminal trial and to make it impossible for the trial judge to proceed with the case until the appeal had been disposed of”. This is because the trial judge is in the best position to assess the evidence and the circumstances of the case, and to make decisions that are in the interests of justice. Allowing interlocutory appeals would also lead to delays and inefficiencies in the criminal justice system. In addition, the Court of Appeal in Yap Keng Ho v Public Prosecutor [2007] 1 SLR(R) 259 at [6] held that “the law does not countenance such premature applications in the middle of trial” unless there is something “imminently fatal to the applicant’s case”. The Court of Appeal in Azman bin Jamaludin v Public Prosecutor [2012] 1 SLR 615 at [20] also observed that “the trial judge is in the best position to assess the evidence and the circumstances of the case” and that “errors can be corrected on appeal”. Finally, the Court of Appeal in Ng Chye Huey and another v Public Prosecutor [2007] 2 SLR(R) 106 at [29] stated that “if every issue were to be litigated separately at every opportunity, the criminal trial would be seriously impeded and delayed”. — Per Tay Yong Kwang JCA, Para 20

Although that quotation is lengthy, it is central to the court’s reasoning because it explains why the High Court refused to treat CM 30 as a permissible shortcut. The court’s concern was not merely formalism; it was the preservation of orderly trial procedure and the avoidance of piecemeal litigation. (Para 20)

The court also referred to a later passage from Xu Yuanchen discussing the difficulty of determining whether to exercise discretion at an interlocutory stage, because the relevant circumstances are often incomplete. That concern was especially acute in the present case because the High Court was being asked to decide a witness-admission issue without the trial judge having ruled on the changed circumstances. (Para 25)

"For s 283 applications such as CM 30 here, the High Court will face great difficulty in determining whether to exercise the discretion in s 283 at an interlocutory stage, as if it were the trial court." — Per Tay Yong Kwang JCA, Para 25

Why Did the Court Say the Witness Issue Belonged to the Trial Judge?

The court’s answer was that s 283 CPC is a power for the court hearing the substantive matter to exercise. The provision is designed to be used by the judge who is already seized of the trial, who knows the evidential context, and who can assess whether the witness should be summoned, examined, recalled, or re-examined in the interests of justice. (Paras 18, 29)

"It is clear from a proper reading of s 283 CPC that the power relating to witnesses is for the court hearing the substantive matter to which the evidence relates to exercise." — Per Tay Yong Kwang JCA, Para 29

That statement is the clearest articulation of the court’s ratio. It means that the statutory power is not free-floating and cannot be detached from the trial in which the evidence is sought. The trial judge, not the High Court, is the decision-maker in the first instance. (Paras 18, 29)

The court also noted that no application had been made to the District Judge based on the asserted change in circumstances. Even if such an application had been made and dismissed, the High Court would still not exercise appellate or revisionary jurisdiction to intervene in interlocutory matters such as the admission or rejection of evidence while the trial was ongoing. This underscores the court’s view that the proper sequence is trial-level decision first, appellate or revisionary review only later, and only where the legal threshold is met. (Para 29)

"No application was made to the DJ based on the asserted change in circumstances in this case but, as explained earlier, even if the DJ had heard and dismissed a s 283 application in the course of the ongoing Trial, it is clear that the High Court would not exercise its appellate or its revisionary jurisdiction to intervene in interlocutory matters such as the admission or rejection of evidence while the Trial is ongoing." — Per Tay Yong Kwang JCA, Para 29

Why Did the Court Dismiss CM 30 Without Deciding Whether the Witness’s Evidence Was Essential?

The court expressly declined to comment on the substantive issue whether the witness’s intended testimony was “essential to making a just decision in the case” within the meaning of s 283(2) CPC. It said that issue should be determined by the trial court. The court therefore confined itself to the procedural ground and did not purport to decide the merits of the witness application. (Para 15)

"I dismissed CM 30 on the procedural ground. I will not comment on the substantive issue of whether the Witness’ intended testimony is “essential to making a just decision in the case” within the meaning of s 283(2) of the CPC as this is an issue that should be determined by the trial court." — Per Tay Yong Kwang JCA, Para 15

This restraint is significant because it shows the court’s respect for the institutional role of the trial judge. The High Court did not attempt to substitute its own assessment of the witness’s importance for that of the judge conducting the trial. Instead, it held that the applicant had chosen the wrong forum and that the motion therefore failed at the threshold. (Paras 15, 18, 29)

That approach also explains why the court did not need to resolve the applicant’s factual claim that the witness had become available due to easing travel restrictions in China. Even if that factual change were accepted, it would not alter the procedural conclusion that the application belonged before the District Judge. (Paras 10, 15, 29)

Why Was CM 30 Described as Frivolous, and What Costs Order Followed?

The court held that CM 30 was frivolous and bound to fail. On that basis, it ordered the applicant to pay the Prosecution costs of $2,000. The court also referred to s 409 CPC, which empowers the relevant court to order costs on an indemnity basis or otherwise fixed by the court if a criminal motion is dismissed and is frivolous, vexatious, or otherwise an abuse of process. (Paras 28, 29, 30)

"Costs 409. If the relevant court dismisses a criminal motion and is of the opinion that the motion was frivolous or vexatious or otherwise an abuse of the process of the relevant court, it may, either on the application of the respondent or on its own motion, order the applicant of the criminal motion to pay to the respondent costs on an indemnity basis or otherwise fixed by the relevant court." — Per Tay Yong Kwang JCA, Para 28

"In my judgment, CM 30 was frivolous and was bound to fail." — Per Tay Yong Kwang JCA, Para 29

"Accordingly, I dismissed CM 30 and ordered the applicant to pay the Prosecution costs of $2,000." — Per Tay Yong Kwang JCA, Para 30

The costs order is important because it signals the court’s view that the motion was not merely mistaken but sufficiently lacking in merit to justify an adverse costs consequence. The amount ordered was fixed at $2,000, and the judgment ties that order to the procedural impropriety of the application. (Paras 29, 30)

For practitioners, the costs ruling serves as a caution that attempts to bypass the trial court in interlocutory criminal matters may attract not only dismissal but also a financial sanction. The judgment therefore has practical significance beyond the immediate dispute over the witness. (Paras 28, 29, 30)

Why Does This Case Matter for Criminal Procedure Practice?

This case matters because it clarifies the proper forum for applications under s 283 CPC. The court made clear that such applications are for the court hearing the substantive matter, not for the High Court to determine in the abstract while the trial is ongoing. That clarification is especially useful where parties may be tempted to seek strategic intervention from a superior court after trial-level proceedings have become difficult. (Paras 18, 29)

"Clearly, s 283 does not contemplate an application being made to a higher court, whether by invoking its appellate or its revisionary jurisdiction, while the proceedings in the trial court are still going on." — Per Tay Yong Kwang JCA, Para 18

The case also reinforces the broader policy against interlocutory intervention in criminal trials. The court’s reliance on authorities such as Hoo Chang Chwen, Yap Keng Ho, Azman bin Jamaludin, and Ng Chye Huey shows that Singapore criminal procedure strongly disfavors fragmented litigation and mid-trial appeals or revisions. The judgment therefore fits within a coherent line of authority protecting the integrity and efficiency of criminal trials. (Para 20)

Finally, the case is a reminder that even where a party asserts a change in circumstances, the existence of a new factual development does not automatically justify bypassing the trial judge. The procedural sequence still matters: the trial court must first be asked to exercise the statutory power, and only then can any higher-court review be considered if the legal conditions for such review are met.
