Background
On 21 January 2023, Ong Cheng Cheng (“OCC”) was assaulted by her brother, Ong Cheng Poh (“OCP”), in the family home during a Chinese New Year reunion. OCP pushed OCC to the floor and struck her face; she was hospitalised for two nights with soft-tissue injuries, bleeding from the left ear, and bruising, though no fractures were found. After lodging a police report and a Magistrate’s Complaint, OCC commenced a private prosecution against OCP for Voluntarily Causing Hurt in April 2024. She had also obtained a personal protection order against OCP with his consent in October 2023.
At a court mention in June 2024, the court noted the matter was a “family dispute” and directed OCP’s solicitors to write to the Attorney-General’s Chambers (“AGC”) regarding the private prosecution. On 29 July 2024, the Attorney-General (“AG”), acting as Public Prosecutor, exercised the power under s 13 of the Criminal Procedure Code 2010 to intervene and discontinue the proceedings, resulting in OCP being given a discharge not amounting to acquittal. The AGC subsequently informed OCC that the decision was taken “after consideration of all facts and circumstances” and that OCP would receive a stern police warning in lieu of prosecution.
Over the following months OCC sought redress through non-litigation channels — writing to her Member of Parliament, the Ministry of Law, and the Prime Minister’s Office — without success. On 4 March 2026, approximately 19 months after the three-month limitation period under O 24 r 5(2) of the Rules of Court 2021 had expired, she filed Originating Application No 248 of 2026 seeking permission to apply for a Quashing Order and a Mandatory Order to compel the AG to reconsider the Discontinuance Decision.
The Court’s Holding
Justice Kwek Mean Luck refused to grant an extension of time. Applying the fact-sensitive inquiry articulated in Per Ah Seng Robin v Housing and Development Board [2016] 1 SLR 1020, the court accepted that OCC could not be faulted for pursuing non-litigation avenues up to 5 June 2025, when the Prime Minister’s Office replied. However, the court found that the subsequent nine-month gap before OA 248 was filed — including a four-month delay after the AGC’s final letter of 6 November 2025 — was not satisfactorily explained. OCC’s personal circumstances (serving as her mother’s deputy, her mother’s brief hospitalisations, and home renovations) did not account for a period during which she plainly retained access to legal counsel. Ignorance of the three-month limitation period was also rejected as an excuse, given that solicitors had been acting for OCC since July 2024.
The court nonetheless addressed the merits of the permission application. On OCC’s first ground — breach of Article 12(1) of the Constitution — the court found she had not identified any comparator in equally situated circumstances. The only case she cited, PP v Tobin Lau Chee Bing [2019] SGDC 178, involved a public prosecution for a more severe assault between former partners, and was materially different in both the nature of the relationship and the gravity of injuries sustained. Without satisfying the first step of the Syed Suhail two-stage equality test, no prima facie case was established.
On OCC’s second ground — alleged arbitrariness in the PP’s exercise of prosecutorial power — the court held that neither the existence of CCTV evidence, nor OCP’s willingness to plead guilty, nor the AGC’s refusal to disclose correspondence from OCP’s solicitors, raised a reasonable suspicion of bad faith or extraneous purpose. Consistent with Ramalingam Ravinthran v Attorney-General [2012] 2 SLR 49 and Xu Yuan Chen v Attorney-General [2022] 2 SLR 1131, the PP is entitled to weigh a broad range of factors beyond legal guilt, has no general obligation to disclose reasons for prosecutorial decisions, and is not obliged to reveal correspondence that may have informed those decisions. The application for permission was dismissed, and costs of $7,000 plus disbursements of $573.80 were awarded to the AG.
Key Takeaways
- Under the Rules of Court 2021, although the express power to extend time for judicial review applications (formerly O 53 r 1(6), ROC 2014) was not re-enacted, the court retains an inherent discretion under O 3 r 2(1) to permit out-of-time applications in the interests of justice; the test remains whether the delay has been satisfactorily accounted for.
- Pursuing non-litigation remedies — through MPs, ministers, or government offices — may justify delay while those avenues are actively pursued, but unexplained inactivity after those channels are exhausted will not be excused, even where the applicant faces personal hardships.
- To establish a prima facie case of unequal treatment by the Public Prosecutor, an applicant must identify a comparator who is in a virtually identical situation; a public prosecution case is not an appropriate comparator for a private prosecution discontinued by the PP.
- The existence of strong evidence of guilt (such as CCTV footage) or an accused’s willingness to plead guilty does not, without more, give rise to a reasonable suspicion that the PP acted arbitrarily in declining to prosecute; the PP may lawfully weigh moral blameworthiness, the family context, remorse, and public interest considerations.
- The PP has no obligation to disclose either the reasons for a prosecutorial decision or correspondence received from accused persons that may have influenced that decision.
Why It Matters
This decision reinforces the very narrow scope of judicial review available to private prosecutors whose proceedings are taken over and discontinued by the Public Prosecutor. The judgment clarifies that courts applying the ROC 2021 retain a residual discretion to extend time for judicial review applications, but confirms that unexplained delay — particularly where legal representation was available throughout — will be fatal to such applications. The ruling also signals that the transition from ROC 2014 to ROC 2021 did not substantively alter the legal framework governing late applications for permission to seek judicial review.
More broadly, the case illustrates the formidable evidential burden on applicants challenging prosecutorial decisions on equal-protection or arbitrariness grounds. Complainants who feel aggrieved by the PP’s decision to intervene in a private prosecution must do more than point to factual similarities with a chosen comparator; they must demonstrate virtual identity of circumstances, and they must do so promptly. The decision affirms that Singapore courts will not second-guess the PP’s assessment of public interest merely because an offender was willing to plead guilty or inculpatory evidence existed.
