Summary
Kong Swee Eng v Public Prosecutor [2022] SGCA 65 is a Court of Appeal decision arising from a criminal reference motion under s 397(1) of the Criminal Procedure Code (CPC). The applicant, Kong Swee Eng, had been acquitted by the District Court on ten charges under s 6(b) of the Prevention of Corruption Act, but the High Court reversed that outcome in part and convicted her on eight of the ten charges. Kong then sought leave to refer a question of law of public interest to the Court of Appeal.
The central issue in the motion concerned the approach an appellate court should take where a defence is raised by an accused person, yet the Prosecution elects not to call a material witness who could conclusively support or rebut that defence. The applicant framed the question around whether the appellate court should reverse an acquittal without first exercising its power under s 392 CPC to take or direct additional evidence (namely, the evidence of the material witness).
The Court of Appeal’s analysis focused on the statutory threshold for criminal references under s 397(1) CPC, including whether the proposed question was a question of law of public interest that arose from the High Court’s decision and affected the outcome of the case. The Court ultimately determined that the requirements were not satisfied, and the motion for leave to refer was dismissed.
What Were the Facts of This Case?
The applicant, Kong Swee Eng, and her husband owned Rainbow Offshore Supplies Pte Ltd (“Rainbow”), a company supplying equipment and materials for the oil and gas industry. At the material time, Rainbow’s only customer was Jurong Shipyard Pte Ltd (“JSPL”). JSPL’s procurement department was therefore central to Rainbow’s commercial prospects, and the evidence at trial indicated that most of the employees who received the alleged gratification worked in that procurement function.
In 2016, following investigations by the Corrupt Practices Investigation Bureau, Kong was charged with ten counts under s 6(b) of the Prevention of Corruption Act. The charges alleged that she corruptly gave various forms of gratification to JSPL employees between 2008 and 2013, with the alleged purpose of advancing Rainbow’s business interests. The prosecution case, in broad terms, was that the gratification was not merely commercial inducement but was given with corrupt intent as contemplated by the PCA.
At trial in the District Court, Kong advanced several defences. The most significant was what the courts later referred to as the “special relationship” defence. Kong’s position was that Rainbow and JSPL had a unique business relationship such that Rainbow was effectively guaranteed JSPL’s custom. On her case, if Rainbow was guaranteed JSPL’s business, then giving gratification to JSPL employees would not have been necessary to “advance” Rainbow’s business interests. That, in turn, was said to negate the mens rea element—specifically, the corrupt intent required for the offences.
Procedurally, the “special relationship” defence was not raised at the outset. It was only after Kong testified in her own defence that she raised the defence. The defence asserted that only four persons were privy to the alleged special relationship: Kong herself; her husband, Mr Huan Ming Chye Michael; JSPL’s CEO at the time of trial, Mr Wong Weng Sun; and JSPL’s previous CEO, Mr Tan Kim Kuan. Notably, Mr Wong and Mr Tan were not called by the Prosecution. Mr Huan testified for the Prosecution and suggested that there was a unique business relationship between Rainbow and JSPL, though he did not go so far as to say that Rainbow was guaranteed JSPL’s custom.
What Were the Key Legal Issues?
The immediate legal issue in the Court of Appeal was not whether Kong was guilty of the PCA charges on the merits. Rather, it was whether the Court of Appeal should grant leave under s 397(1) CPC to refer a question of law of public interest. That statutory gatekeeping function requires the applicant to satisfy specific threshold requirements.
The proposed question of law, as amended, was framed around appellate procedure and evidential fairness. It asked: where a defence has been raised by an accused person, but the Prosecution elects not to call a material witness central to disproving that defence, should an appellate court reverse an acquittal without exercising its power under s 392 CPC to hear the evidence of that material witness?
Underlying this question were two related legal concerns. First, the applicant argued that the Prosecution’s decision not to call a material witness could create “reasonable doubt” because of a “lack of evidence”. Second, she contended that the appellate court’s approach must respect the presumption of innocence and the Prosecution’s burden to prove guilt beyond reasonable doubt. The question thus implicated how appellate courts should manage evidential gaps when reversing acquittals.
How Did the Court Analyse the Issues?
The Court of Appeal began by setting out the procedural history that led to the criminal reference motion. The District Judge acquitted Kong on all ten charges. The District Judge’s reasoning, as later summarised, was that the “special relationship” defence was not inherently incredible and created reasonable doubt on whether there was an objectively corrupt element and whether Kong possessed the requisite guilty knowledge. Because the Prosecution did not rebut the defence, the District Judge concluded that the acts could not be gratification given with corrupt intent and could not be inducements to advance Kong’s business interests.
On appeal, the High Court reversed the District Judge’s acquittal on eight charges. The High Court held that the “special relationship” defence was inherently incredible. It emphasised factors such as inconsistent accounts by Kong, the absence of corroborative evidence, and the lack of clarity as to how the alleged special relationship operated alongside JSPL’s procurement processes. The High Court also found that the defence was contradicted by other evidence adduced at trial. On that basis, the High Court concluded that Kong had not met her evidential burden and that the Prosecution’s failure to call Mr Wong was not fatal.
After the High Court’s decision, Kong sought leave to review the High Court’s decision by relying on two additional statements from Mr Wong. The High Court dismissed that application, holding that the statements were substantially similar to Mr Wong’s earlier investigation statements already disclosed at trial and could have been adduced earlier with reasonable diligence. Further, the statements did not conclusively show that Rainbow was guaranteed JSPL’s custom; rather, they suggested JSPL had relationships with “strategic suppliers” who still had to meet conditions to secure JSPL’s custom.
Against that backdrop, the Court of Appeal turned to the statutory threshold for criminal references under s 397(1) CPC. The Court reiterated the requirements articulated in Public Prosecutor v Lam Leng Hung and others [2018] 1 SLR 659 at [51]. These include: (a) the reference must relate to a criminal matter decided by the General Division of the High Court in its appellate or revisionary jurisdiction; (b) the reference must relate to a question of law of public interest; (c) the question must have arisen from the case before the General Division; and (d) the determination of the question must have affected the outcome.
Although the parties agreed that the first requirement was met, the Court’s focus was on the second, third, and fourth requirements. The applicant argued that the question was one of law of public interest because it would clarify the approach of an appellate court when it is aware of a material witness who could conclusively support or rebut a defence. She also argued that such clarification would affect accused persons’ rights, including the presumption of innocence and the Prosecution’s burden to prove guilt beyond reasonable doubt. She relied on Jagatheesan s/o Krishnasamy v Public Prosecutor [2006] 4 SLR(R) 45 for the proposition that reasonable doubt may arise from a “lack of evidence”.
However, the Court of Appeal’s analysis indicated that the proposed question did not cleanly arise from the High Court’s reasoning in a way that satisfied the statutory threshold. The High Court’s decision had turned on its assessment that the “special relationship” defence was inherently incredible and that Kong had not met her evidential burden. In other words, the High Court did not accept that the defence was raised in a manner that required the Prosecution to call the material witness to rebut it. The Court of Appeal therefore treated the applicant’s question as, at least in substance, seeking a general rule that did not align with the High Court’s actual basis for reversing the acquittal.
Further, the Court noted that neither the Prosecution nor the Defence had invited the High Court to exercise its power under s 392 CPC to take or direct the taking of Mr Wong’s evidence. This procedural context mattered because it suggested that the High Court’s decision was not made in a vacuum of evidential uncertainty that it had the opportunity to cure under s 392. Instead, the High Court had evaluated the defence and the evidence before it and concluded that the defence failed on credibility and evidential sufficiency.
In dismissing the motion, the Court of Appeal effectively signalled that criminal references under s 397(1) CPC are not meant to be used to obtain advisory guidance on hypothetical procedural scenarios. Rather, the question must arise from the General Division’s decision and must be shown to have affected the outcome. Where the High Court’s reversal rests on its assessment of inherent incredibility and evidential burden, the appellate court’s additional evidence powers under s 392 may not be the legally decisive issue for the purposes of a criminal reference.
What Was the Outcome?
The Court of Appeal dismissed Kong Swee Eng’s application for leave to refer the amended question of law of public interest under s 397(1) CPC. As a result, the Court of Appeal did not grant a substantive ruling on the broader procedural principle framed by the applicant.
Practically, the dismissal meant that the High Court’s partial conviction and the acquittal on the remaining two charges stood as the final outcomes in the underlying appeal, and Kong did not obtain appellate clarification from the Court of Appeal on the evidential approach she sought.
Why Does This Case Matter?
This case matters primarily for criminal procedure practitioners because it illustrates the strict threshold requirements for criminal references under s 397(1) CPC. Even where an applicant can articulate a question that appears to engage fairness and the presumption of innocence, the Court of Appeal will still require that the question be a genuine question of law of public interest that arose from the General Division’s decision and affected the outcome.
For defence counsel, the case underscores the importance of procedural strategy at the appellate stage. If the evidential gap is central, parties should consider whether to invite the appellate court to exercise its powers under s 392 CPC. The Court’s observation that neither party invited the High Court to take or direct additional evidence suggests that, in future cases, counsel should be prepared to make explicit submissions on s 392 where the evidential issue is truly decisive.
For prosecutors, the decision highlights that appellate reversals of acquittals may be sustained where the appellate court finds the defence inherently incredible or insufficiently supported, without necessarily treating the non-calling of a witness as fatal. The case therefore reinforces that the evidential burden and credibility assessment can be legally determinative, potentially reducing the relevance of general “material witness” arguments unless they directly engage the appellate court’s reasoning.
