Summary
In Tan Wei Wen v Public Prosecutor [2023] SGCA 34, the Court of Appeal dealt with a litigant’s attempt to challenge a High Court decision after the prosecution against him had been withdrawn at the District Court stage. The applicant, Tan Wei Wen, sought compensation on the basis that the prosecution was “wrongful” and allegedly not brought in good faith. After the District Court dismissed his compensation application and the High Court upheld that dismissal, Tan Wei Wen filed further applications in the Court of Appeal to extend time to appeal, to reopen a concluded case, and to obtain permission to refer a question of law.
The Court of Appeal emphasised a fundamental structural principle in Singapore criminal procedure: there is only one tier of appeal in criminal matters. Once the High Court has exercised its appellate jurisdiction, no further appeal lies to the Court of Appeal. Accordingly, the Court dismissed CM 7 and CM 8 and, as a consequence, dismissed CCA 1. The decision also clarifies that procedural labels—such as “review” or “reopening”—cannot be used to circumvent the statutory and constitutional architecture governing criminal appeals.
What Were the Facts of This Case?
The applicant, Tan Wei Wen, was charged in the District Court on 26 November 2019 with two counts of insulting the modesty of a woman under s 509 of the Penal Code (Cap 224, 2008 Rev Ed). The charges related to alleged conduct in May 2018 involving the sending of videos depicting sexual acts. In the first charge, he was alleged to have sent a video of himself stroking his penis to the complainant on 5 May 2018. In the second charge, he was alleged to have sent another video depicting a male stroking his penis, accompanied by crude words with sexual connotations, and with a photograph of the complainant in the background, on 7 May 2018.
Tan Wei Wen claimed trial. The trial was scheduled for 21 and 22 July 2020. About two weeks before trial, on 6 July 2020, the Prosecution applied to withdraw the charges. On 7 July 2020, the District Court granted a discharge amounting to an acquittal. Importantly, this order was made without requiring the parties’ attendance because of the COVID-19 pandemic.
More than eight months later, on 25 March 2021, Tan Wei Wen sought compensation from the Prosecution. He applied for a compensation order under s 359(3) of the Criminal Procedure Code (Cap 68, 2012 Rev Ed). His case was that the prosecution was “wrongful to even begin with” and that it had not been brought in good faith. He sought $3,000 for alleged “abuse of juridical process” and $10 per day from the date his phone was seized by the police, claiming “loss of income from phone rental”.
To support his claim of wrongful prosecution, Tan Wei Wen relied on two broad strands. First, he argued that the prosecution lacked sufficient evidence from the outset, pointing to the Prosecution’s decision to withdraw the charges and the fact that no evidence was admitted at the charging stage. Second, he alleged malice or improper motive, asserting that he was charged after he refused to accept a written warning for an alleged offence under s 292 of the Penal Code relating to the sale of obscene books; that the Prosecution “dragged out” the case to coerce him to plead guilty; and that a “plead-guilty offer” was made to incentivise him to plead guilty.
What Were the Key Legal Issues?
The Court of Appeal identified three principal issues. The first was whether Tan Wei Wen should be granted an extension of time to file a Notice of Appeal and Petition of Appeal against the High Court’s decision in HC/MA 9129/2022/01 (“MA 9129”). This required the Court to consider the procedural constraints governing criminal appeals and the applicant’s ability to satisfy the threshold requirements for an extension.
The second issue was whether permission should be granted for a “review application” in respect of the decision in MA 9129 if the Court of Appeal were to regard the applicant’s filing as a review application. This issue went to the heart of whether the Court could entertain a further challenge to a High Court decision made in appellate jurisdiction, and whether the applicant could recharacterise his attempt as a review rather than an appeal.
The third issue concerned whether permission to refer a question of law under s 397 of the Criminal Procedure Code should be granted if the Court of Appeal were to regard the applicant’s filing as an application to refer a question of law. This required the Court to examine the statutory purpose and limits of s 397, and whether the applicant’s proposed route could be used to obtain substantive reconsideration of a concluded criminal appellate decision.
How Did the Court Analyse the Issues?
The Court’s analysis began with the procedural architecture of criminal appeals in Singapore. It reiterated that “it is settled law that there is only one tier of appeal in criminal matters”. In practical terms, appeals lie from the State Courts to the High Court. Once the High Court has decided the matter in the exercise of its appellate jurisdiction, no appeal lies to the Court of Appeal against that decision. The Court cited its own prior decisions, including Mah Kiat Seng v Public Prosecutor [2021] SGCA 79, Tang Keng Lai v Public Prosecutor [2021] 2 SLR 942, and Public Prosecutor v Lim Yong Soon Bernard [2015] 3 SLR 717, to confirm that the Court of Appeal cannot function as a further appellate forum in criminal cases.
Against that backdrop, the Court examined the applicant’s filings. Tan Wei Wen had filed two motions: CM 7, seeking an extension of time to file the Notice of Appeal and Petition of Appeal within 14 days from an order to be made; and CM 8, seeking permission to file the notice and petition of appeal to “reopen” a concluded case. After these motions were filed, he also filed CCA 1, which appeared to be an appeal to the Court of Appeal against the High Court Judge’s decision in MA 9129. The Court treated these applications as intrinsically connected to challenging the High Court’s appellate decision.
On the substantive compensation claim, the Court noted that the District Court had dismissed Tan Wei Wen’s compensation application on 28 June 2022. The District Court applied the principles from Parti Liyani v Public Prosecutor [2021] 5 SLR 860. In Parti Liyani, the High Court had explained that an applicant may establish that a prosecution was frivolous or vexatious by proving, on a balance of probabilities, either (a) evidential insufficiency—meaning that an objective, reasonable Deputy Public Prosecutor would not have considered there was sufficient evidence to render the case fit to be tried—or (b) malice, dishonesty, or an improper motive. The District Court found that Tan Wei Wen had not shown evidential insufficiency or improper motive.
Although the extract provided is truncated, the Court of Appeal’s reasoning in this case is anchored in the procedural point that even if the applicant disagreed with the High Court’s decision, the Court of Appeal had no jurisdiction to entertain what was, in substance, a further appeal. The Court therefore dismissed CM 7 and CM 8 for the reasons it had explained at the hearing, and it followed that dismissal by dismissing CCA 1. The Court’s approach indicates that it was not prepared to allow procedural mechanisms—extension of time, “reopening”, or permission to frame the matter as a review or reference—to bypass the one-tier appellate structure.
In particular, the Court’s treatment of the “review” and “reference” issues reflects a concern with substance over form. If the applicant’s objective was to obtain reconsideration of the High Court’s appellate decision, then characterising the application as a review or as a question-of-law reference would not alter the underlying jurisdictional limitation. The Court also implicitly signalled that s 397 is not a general gateway for re-litigation of issues already determined in the criminal appellate chain, but a narrowly tailored statutory mechanism that must be invoked within its proper scope.
What Was the Outcome?
The Court of Appeal dismissed CM 7 and CM 8. As a consequence, it also dismissed CCA 1. The practical effect of the decision is that Tan Wei Wen’s attempt to challenge the High Court’s decision in MA 9129 could not proceed in the Court of Appeal, whether framed as an appeal, a reopening, a review application, or a reference of a question of law.
For litigants, the outcome underscores that procedural applications cannot be used to circumvent jurisdictional limits. For practitioners, it confirms that once the High Court has decided a criminal matter in appellate jurisdiction, the Court of Appeal will not entertain further challenges that amount to a second appeal.
Why Does This Case Matter?
Tan Wei Wen v Public Prosecutor is significant primarily for its reaffirmation of the one-tier appellate structure in Singapore criminal procedure. While the case arises from a compensation dispute under s 359(3) of the Criminal Procedure Code, the Court of Appeal’s decision is driven by jurisdictional and procedural constraints rather than by a detailed re-evaluation of the merits of the wrongful prosecution claim.
For lawyers, the case is a useful reminder that the Court of Appeal will scrutinise the substance of an applicant’s application. Attempts to recharacterise an impermissible appeal as a “review” or to seek permission to reopen a concluded decision may fail if the effect is to obtain a further appellate review of a High Court decision made in appellate jurisdiction. This is particularly relevant for litigants in person, who may not appreciate the technical limits on criminal appellate routes.
From a practical standpoint, the decision also reinforces the importance of timely and properly structured appellate filings. CM 7 sought an extension of time, but the Court’s dismissal indicates that even where an extension might be considered, it cannot cure a fundamental jurisdictional defect—namely, the absence of a further appeal to the Court of Appeal in criminal matters after the High Court has acted in appellate capacity.
