Summary
In CHJ v Public Prosecutor ([2025] SGCA 38), the Court of Appeal dismissed both an appeal against conviction and sentence and a related application to admit fresh evidence. The appellant, CHJ, was convicted after trial of two charges of sexual assault involving penetration by digital penetration of his wife (the complainant), contrary to s 376(2)(a) of the Penal Code. He was also convicted of an amalgamated charge of obstructing the course of justice under s 204A(b) of the Penal Code.
The Court of Appeal held that the defences of consent and mistake of fact could not be made out on the facts. It further clarified that the “unusually convincing” standard of proof did not apply because the complainant’s evidence was not the sole basis for conviction; there was corroboration from communications and statements made by the appellant around the time of the offences. On sentencing and charging, the Court agreed with the trial judge’s approach to (i) treating two closely timed penetrations as two separate incidents and (ii) ordering the imprisonment terms to run concurrently for the penetration charges but consecutively with the obstruction charge, given the different legal interests and temporal separation.
What Were the Facts of This Case?
The appellant was convicted of sexually assaulting his wife by digital penetration on two occasions. The offences were committed in July 2020, in the bedroom, and the complainant alleged that the penetration occurred without her consent. The trial judge found that the complainant’s account was credible and that the appellant’s defences—consent or, alternatively, honest mistake of fact—were not supported by the evidence. The Court of Appeal, agreeing with the trial judge, emphasised that the conviction did not rest solely on the complainant’s testimony.
On the night of 13 July 2020, the episode involved an interruption caused by the couple’s son. Although the interruption was brief, the Court of Appeal accepted the trial judge’s reasoning that it caused a break in the sexual penetration. This factual finding was central to the charging decision: the prosecution proceeded on the basis that there were two incidents of penetration occurring one after the other within a short interval and in the same place, but separated by the interruption.
Following the sexual offences, the appellant was also charged with obstructing the course of justice. The obstruction charge related to events occurring about three months later. The Court of Appeal described the relevant conduct as involving four phone calls made by the appellant to the complainant’s mother between 11 and 17 October 2020. In those calls, the appellant sought to persuade and pressure the complainant to withdraw her police report and to influence the complainant’s narrative in a manner that would undermine the criminal case.
After the trial, the appellant appealed against both conviction and sentence. Shortly before the appeal hearing, he filed a criminal motion seeking leave to adduce further evidence. The fresh evidence consisted of (a) a divorce originating application filed by the complainant against the appellant in March 2025 and served on him in prison, and (b) correspondence between the parties’ counsel in the divorce proceedings from December 2024 to March 2025, relating to the couple’s two children. The appellant argued that the divorce materials showed embellishment and a changed narrative, and that the complainant had a motive to restrict his access to the children and to make false allegations in the criminal matter.
What Were the Key Legal Issues?
The Court of Appeal had to decide whether the fresh evidence should be admitted on appeal. This required consideration of the statutory framework for admitting further evidence in criminal appeals, including whether the proposed evidence would have an important influence on the result of the appeal.
On the substantive appeal, the Court addressed several legal issues. First, it considered whether the “unusually convincing” standard of proof should apply. This standard is sometimes invoked where the prosecution’s case depends essentially on the uncorroborated evidence of a complainant in sexual offence cases. The appellant contended that the complainant’s evidence was the primary basis for conviction and that the court should therefore apply a heightened standard.
Second, the Court considered whether there should have been one charge rather than two for sexual penetration. The appellant argued that where two penetrations occur within a very short interval and in the same place, they should be treated as part of a single transaction for charging purposes. The Court also had to address the sentencing consequences of the charging structure and the proper application of the Criminal Procedure Code provisions on consecutive and concurrent sentences.
Finally, the Court considered whether the appellant’s phone calls to the complainant’s mother fell within Explanation 1 to s 204A of the Penal Code. Explanation 1 provides that a mere warning to a witness that he or she may be prosecuted for perjury is insufficient to constitute an offence. The appellant argued that his communications were essentially warnings and should not amount to obstruction. There was also an ancillary issue as to whether the four phone calls could be amalgamated into a single obstruction charge as a course of conduct.
How Did the Court Analyse the Issues?
On the fresh evidence application (CM 10), the Court of Appeal dismissed the motion. It held that the proposed divorce documents and correspondence would not have an important influence on the result of the appeal against conviction and sentence. The Court reasoned that the appellant’s arguments were largely premised on the assumption that the “unusually convincing” standard of proof applied. However, the Court later explained that such a standard did not apply because the complainant’s evidence was not the sole basis for conviction.
The Court also examined the nature of the alleged inconsistencies between the complainant’s criminal trial evidence and what was stated in the divorce originating application. Importantly, the appellant did not dispute that sexual penetration occurred. His defence was that the penetration was consensual, or that he honestly believed it was consensual. The Court observed that any inconsistencies related to minute details about the events, and did not detract from the complainant’s core assertion that the penetration took place without consent.
As for the correspondence about custody and access to the children, the Court held that it merely showed the complainant was not amenable to the appellant’s proposals. The Court did not see how correspondence from December 2024 to March 2025 could bear on the complainant’s state of mind in July 2020 when the sexual penetration took place. In other words, the fresh evidence did not meaningfully undermine the trial findings on consent or mistake of fact.
Turning to the appeal against conviction, the Court of Appeal agreed with the trial judge’s factual findings on the material issues. It stated that there could be no reasonable doubt that the defences of consent and mistake of fact could not be made out. The Court’s reasoning was anchored in the evidential picture as a whole, not merely the complainant’s testimony.
Regarding the “unusually convincing” standard, the Court rejected the appellant’s legal submission. It accepted that the standard might be relevant where the prosecution’s case rests essentially on the complainant’s evidence. However, in this case, the Court found corroboration in communications between the appellant and his sister on 14 July 2020, in the first video recorded interview conducted on 14 July 2020, and in the first cautioned statement given by the appellant on 15 July 2020. Because the evidence of penetration and the absence of consent did not come from the complainant alone, the “unusually convincing” standard was not applicable.
On the charging issue—whether there should have been one penetration charge—the Court agreed with the trial judge that the son’s interruption caused a break in the sexual penetration, even though the interruption was brief. This supported the prosecution’s decision to treat the two penetrations as two separate incidents justifying two penetration charges. The Court’s analysis reflects a pragmatic approach to how interruptions can segment conduct for charging purposes, particularly where the interruption breaks the continuity of the act.
The Court then addressed the sentencing structure. It explained that the existence of three distinct charges involving imprisonment meant that two imprisonment terms had to run consecutively, as mandated by s 307(1) of the Criminal Procedure Code. However, it agreed that the trial judge correctly ordered the imprisonment terms for the two penetration charges to run concurrently. The Court noted that the penetration charges involved the same parties and were closely related in time and place, and involved the same legal interest. It further agreed that the concurrent penetration sentences should run consecutively with the obstruction sentence because the obstruction involved events about three months later, a different party (the complainant’s mother), and a different legal interest.
The Court also considered the hypothetical scenario where there might have been only one penetration charge. Even then, it indicated that the trial judge would likely have imposed the same consecutive structure because the penetration and obstruction charges target different legal interests and are separated by several months, even though the obstruction arose as a result of the predicate sexual offences.
On the obstruction charge, the Court analysed whether the appellant’s phone calls fell within Explanation 1 to s 204A of the Penal Code. It held that they did not. The Court reasoned that the appellant’s communications were not a mere warning that the complainant might be prosecuted for perjury. Instead, considered collectively, the calls were clearly aimed at persuading and pressurising the complainant to withdraw her police report and to influence the criminal process. The Court gave examples of what the appellant told the complainant’s mother, including that the children could end up in foster care and that the complainant, the children, and the criminal case would be published in newspapers if the complainant did not withdraw her allegation.
Finally, the Court dealt with the ancillary issue of whether the four phone calls could be amalgamated into one charge. It held that they fell within the wording of ss 124(4) and 124(5) of the Criminal Procedure Code as a course of conduct. The Court therefore found that the amalgamation was lawful.
What Was the Outcome?
The Court of Appeal dismissed the appeal against conviction and sentence. It upheld the trial judge’s findings that the defences of consent and mistake of fact were not made out, and it confirmed that the “unusually convincing” standard of proof did not apply because there was corroborative evidence beyond the complainant’s testimony.
On sentencing, the Court found no reason to disturb the aggregate sentence. It agreed that the global imprisonment term of eight years and six strokes of the cane was not wrong in principle or manifestly excessive. The Court also ordered that the imprisonment term of eight years take effect from 31 March 2023 and lifted the stay on the caning with immediate effect, meaning the corporal punishment would proceed rather than remain suspended pending the appeal.
Why Does This Case Matter?
CHJ v Public Prosecutor is significant for practitioners because it clarifies when the “unusually convincing” standard of proof is (and is not) engaged in sexual offence appeals. The Court’s approach underscores that the standard is not triggered merely because the complainant is the central witness; it depends on whether the prosecution’s case rests essentially on the complainant’s evidence. Where there is corroboration from contemporaneous communications, interviews, or statements by the accused, the Court will be reluctant to apply a heightened standard.
The decision is also useful on charging and sentencing architecture. The Court’s acceptance that brief interruptions can create separate incidents for penetration charges provides guidance on how courts may segment conduct for the purposes of multiple charges. At the same time, the Court’s sentencing analysis illustrates the careful application of the Criminal Procedure Code framework for consecutive and concurrent sentences, distinguishing between charges that protect different legal interests and those that are closely related in time and place.
For obstruction of justice cases, the judgment offers a practical interpretation of Explanation 1 to s 204A of the Penal Code. It demonstrates that communications framed as warnings can still amount to obstruction where they are, in substance, coercive or persuasive attempts to influence a witness’s decision to withdraw or alter testimony. The Court’s emphasis on the collective effect of the calls, including threats of adverse consequences and publicity, will be particularly relevant to future cases involving attempts to influence complainants or witnesses through intermediaries.
