Summary
In Kong Swee Eng v Public Prosecutor [2022] SGHC 50, the High Court considered an application for leave under s 394H of the Criminal Procedure Code (CPC) for the applicant to make a criminal review application against the judge’s earlier decision convicting her. The applicant, Ms Kong, had been convicted on eight charges under s 6(b) of the Prevention of Corruption Act (PCA) after the prosecution’s appeal partially succeeded. She sought leave to review the conviction by relying on two later statements made by a key witness, Wong, in October and November 2021.
The court held that the applicant failed to establish the statutory “legitimate basis” required for leave. Although it was undisputed that Wong’s 2021 statements had not been canvassed at the earlier stages, the court found that the evidence could have been adduced earlier with reasonable diligence. Further, the court concluded that the statements did not meet the high threshold for review evidence: they were not sufficiently reliable, substantial, powerfully probative, and capable of showing “almost conclusively” that a miscarriage of justice had occurred.
Practically, the decision underscores that criminal review is not a second appeal and does not exist to remedy tactical choices at trial or on appeal. Where the defence could reasonably have obtained and used the evidence earlier, and where the new material does not strongly undermine the conviction, leave will be refused.
What Were the Facts of This Case?
The underlying prosecution concerned ten charges against Ms Kong under s 6(b) of the PCA. Broadly, the prosecution alleged that she corruptly gave gratification to personnel in JSPL in order to induce them to favour her business interests in relation to two companies, Rainbow and DMH. JSPL was a principal customer of both companies, and in Rainbow’s case JSPL was its only customer. Ms Kong was directly or indirectly involved in both Rainbow and DMH, making the alleged conduct commercially significant.
To prove the PCA charges beyond a reasonable doubt, the prosecution had to establish both the actus reus and the mental element of corruption. The prosecution needed to show that Ms Kong gave gratification to JSPL personnel and that such gratification was an inducement or reward for the conferment of a benefit. In addition, the court required an objectively corrupt element in the transaction, which the accused must have been subjectively aware of. This framework was articulated by reference to Public Prosecutor v Leng Kah Poh [2014] 4 SLR 1264 at [20].
At trial in the State Courts, Ms Kong claimed trial to all ten charges. She denied giving gratification for several charges and advanced a “special relationship defence”. Her case was that she had a long-standing “special relationship” with the then managing director of JSPL, Wong, and that this relationship explained the commercial arrangements between Rainbow and JSPL without any need for bribery. Ms Kong testified that the special relationship was agreed in 2003 or 2004 between (a) herself and Huan, and (b) Wong and the then CEO of JSPL, KK Tan Senior. She said Wong played an integral role and that the relationship continued until 2013.
According to Ms Kong, the special relationship involved a procurement arrangement in which JSPL would invite Rainbow to quote whenever JSPL intended to place orders, and Wong would then indicate whether the price was too high and invite her to lower it to meet his expectations. Ms Kong testified that because JSPL was Rainbow’s only customer, she would ultimately capitulate during negotiations, resulting in Rainbow being almost always guaranteed JSPL’s custom. On this basis, she argued that even if gratification had been given, it was not an inducement or reward and therefore lacked the objectively corrupt element. She further argued that the subjective guilty knowledge required for corruption was not established.
What Were the Key Legal Issues?
The application was brought under s 394H of the CPC, which requires the applicant to obtain leave before making a criminal review application. The court emphasised that the applicant must disclose a “legitimate basis” for review. The “legitimate basis” test is informed by the sufficiency and miscarriage of justice requirements in s 394J(3) of the CPC, as explained in authorities such as Kreetharan s/o Kathireson v Public Prosecutor [2020] 2 SLR 1175, Rahmat bin Karimon v PP [2021] 2 SLR 860, and Moad Fazid bin Mustaffa v Public Prosecutor [2020] 2 SLR 1364.
In this case, the court treated two requirements as the main battlegrounds. First, under s 394J(3)(b), the court had to consider whether the material in Wong’s 2021 statements could have been adduced earlier with reasonable diligence (the “non-availability requirement”). Second, under s 394J(3)(c), the court had to assess whether the statements were reliable, substantial, powerfully probative, and capable of showing almost conclusively that there had been a miscarriage of justice.
Although it was undisputed that the first requirement in s 394J(3)(a) was satisfied—because Wong’s 2021 statements had not been canvassed at the time of the earlier decision—the court still had to determine whether the applicant met the stringent criteria for leave. The issues therefore focused on both procedural diligence and the substantive quality and impact of the new evidence.
How Did the Court Analyse the Issues?
The court’s analysis began with the non-availability requirement under s 394J(3)(b). Ms Kong argued that Wong’s 2021 statements could not have been adduced earlier even with reasonable diligence because the relevance and materiality of Wong’s evidence only became apparent after the High Court’s appellate decision. She contended that the statements supported the special relationship defence and therefore created a “more than a real possibility” that the earlier decision was wrong, invoking the statutory language in s 394J(5)(a) read with s 394J(6) of the CPC.
The court rejected the argument as to timing and relevance. It held that the inquiry under s 394J(3)(b) is objective and factual: the question is whether the material could have been adduced earlier with reasonable diligence, not when the accused subjectively appreciated the evidence’s significance. In other words, errors of judgment or misapprehension by the accused or counsel about the evidential value of the material cannot, by themselves, satisfy the non-availability requirement. This approach reflects the policy that criminal review should not be used to re-litigate matters that could have been pursued earlier through proper diligence.
Critically, the court found that it was “abundantly clear” that Ms Kong knew all along of the importance of Wong’s evidence to her case on the special relationship. The court reasoned that the special relationship defence was central to her trial strategy. If Wong’s testimony was important to establish the existence and content of that relationship, then reasonable diligence would have required the defence to seek and adduce Wong’s evidence earlier. The court also noted that Wong’s 2021 statements were not wholly novel in substance; rather, their contents were similar to Wong’s earlier investigative statements.
On the prosecution’s side, it was argued that Wong’s 2021 statements were not “new” evidence because they substantially reproduced matters already contained in Wong’s investigative statements recorded during the investigation (including statements recorded on 2 October 2014 and on 14 May 2019 and 11 November 2019). The prosecution further pointed out that these investigative statements had been disclosed to Ms Kong at trial so that she could make an informed decision on whether to call Wong as a witness. Ms Kong did not call Wong after disclosure, which the prosecution characterised as a considered tactical decision. The court accepted the thrust of this argument in assessing reasonable diligence and concluded that the evidence could have been adduced earlier.
Having dealt with s 394J(3)(b), the court turned to s 394J(3)(c), which imposes a demanding standard for review evidence. The court considered whether Wong’s 2021 statements were reliable, substantial, powerfully probative, and capable of showing almost conclusively that there had been a miscarriage of justice. The court’s reasoning, as reflected in the extract, indicates that it was not persuaded that the statements met this threshold.
Ms Kong’s position was that the October and November 2021 statements clarified the “Strategic Supplier” arrangement and described procurement-related incidents and interactions that, in her view, were consistent with the special relationship defence. The October 2021 statement explained that Rainbow was a “Strategic Supplier” for piping and that JSPL’s procurement process could dispense with the usual requirement for three quotes if the Strategic Supplier met certain requirements. The November 2021 statement described an incident where Wong instructed Koay to request Rainbow to participate in a bid by alternative equipment makers, and it also detailed instances where Wong asked Kong to help train personnel in Rainbow’s procurement department.
However, the court did not accept that these statements, even if relevant, were sufficiently compelling to undermine the conviction “almost conclusively”. The court’s approach reflects the principle that review is reserved for exceptional cases where the new evidence is of such quality and impact that it would likely have led to a different outcome. Where the new statements largely reiterate or elaborate on matters already known, and where they do not decisively negate the elements of the offence as found by the appellate court, leave will not be granted.
In addition, the court’s earlier appellate decision had already addressed the special relationship defence. In the High Court’s GD on appeal, it had found that Ms Kong had not discharged her evidential burden regarding the special relationship, meaning the prosecution did not need to rebut it. That context matters: the review evidence would need to do more than support the defence in a general way; it would need to directly and powerfully address the evidential gaps identified by the appellate court.
What Was the Outcome?
The High Court dismissed Ms Kong’s application for leave under s 394H of the CPC. The court held that she did not disclose a legitimate basis for review because the requirements under s 394J(3)(b) and (c) were not satisfied. In particular, Wong’s 2021 statements could have been adduced earlier with reasonable diligence, and they were not shown to be sufficiently reliable and powerfully probative to demonstrate, almost conclusively, a miscarriage of justice.
As a result, Ms Kong was not permitted to proceed to a full criminal review application. The practical effect was that the convictions and sentences arising from the High Court’s earlier appellate decision remained undisturbed.
Why Does This Case Matter?
This decision is significant for practitioners because it clarifies how the leave stage operates in Singapore’s criminal review framework. The court’s emphasis on an objective diligence inquiry under s 394J(3)(b) discourages attempts to justify non-adduction by pointing to hindsight about relevance. Defence counsel must therefore treat disclosure of investigative statements and the availability of key witnesses as opportunities to build the evidential record at trial, rather than as matters to be revisited later through review.
Second, the case illustrates the high evidential threshold for review evidence under s 394J(3)(c). Even where new statements appear to strengthen a defence narrative, the court will scrutinise whether the material is genuinely “powerfully probative” and capable of showing almost conclusively that a miscarriage of justice occurred. This is particularly important in corruption cases where the legal elements include both objective corrupt elements and subjective guilty knowledge; review evidence must engage with these elements, not merely with the broader commercial context.
Third, the decision reinforces the policy that criminal review is not a substitute for appeal or for tactical decisions made at trial. Where the defence had earlier access to substantially similar investigative statements and chose not to call the witness, the court is likely to view later statements as insufficient to satisfy the statutory criteria for leave. For lawyers, the case serves as a reminder to carefully assess witness strategy at trial and to document diligence efforts if later review is contemplated.
