What government decisions can be challenged through judicial review in Singapore?
A wide range of decisions made by public bodies exercising statutory or public functions can potentially be challenged through judicial review, including decisions by government ministries, statutory boards and other agencies, covering matters such as licensing decisions, regulatory enforcement action, and other exercises of administrative power that affect an individual’s or company’s rights or interests.
Judicial review is generally available where a decision has a sufficiently public character, meaning it involves the exercise of a power granted by statute or otherwise recognised as a public function, rather than a purely private or commercial decision, even one made by a government-linked entity, which may not always be amenable to judicial review depending on its specific nature.
Certain categories of decision, particularly those involving matters of high policy such as national security or foreign affairs, may be treated as non-justiciable or subject to a more limited scope of review, reflecting the courts’ recognition that some decisions are more appropriately left to the political branches of government rather than judicial scrutiny.
Because whether a specific decision is amenable to judicial review, and if so on what grounds, depends heavily on the specific nature of the decision and decision maker involved, anyone considering challenging a government decision should seek legal advice early to assess whether judicial review is genuinely available for their specific situation.
Who has standing to apply for judicial review?
An applicant generally needs to demonstrate sufficient interest in the matter to have standing to bring a judicial review application, which typically means showing that the decision being challenged has directly affected the applicant’s own legal rights, interests or legitimate expectations, rather than the applicant simply having a general concern about the decision.
Individuals or companies who are the direct subject of a decision, such as an applicant refused a licence or a company subject to enforcement action, generally have clear standing to challenge that decision, since the decision directly affects their own legal position.
Third parties who are indirectly affected by a decision, such as a competitor affected by a decision benefiting another company, may have standing in some circumstances, though establishing sufficient interest can be more contested for indirectly affected parties compared with those who are the direct subject of the decision.
Because standing requirements can be a genuine obstacle to bringing a judicial review application, particularly for parties who are not the direct subject of the challenged decision, anyone considering judicial review should seek legal advice early to assess whether they are likely to satisfy the standing requirement for their specific situation.
What grounds, such as illegality, irrationality or procedural unfairness, may be relied on?
Illegality as a ground for judicial review covers situations where a public body has acted beyond the powers actually granted to it by law, misdirected itself as to the relevant legal test, or failed to take into account matters it was legally required to consider, or took into account matters it should not have considered in reaching its decision.
Irrationality, sometimes described through the Wednesbury unreasonableness standard, covers decisions so unreasonable that no reasonable decision maker properly directing itself could have reached them, which is generally a demanding standard to meet, reflecting the courts’ general reluctance to substitute their own view of the merits for that of the original decision maker.
Procedural impropriety covers failures in the process by which a decision was reached, such as a failure to give the affected party a fair opportunity to be heard, a failure to give adequate reasons where required, or bias on the part of the decision maker, and this ground often provides a more accessible basis for challenge than illegality or irrationality.
Because each ground has its own specific requirements and the strength of a potential challenge depends heavily on the specific facts, anyone considering a judicial review application should seek legal advice to assess which grounds, if any, are genuinely available on the facts of their particular case.
What permission and filing requirements apply?
An applicant must generally first obtain permission, referred to as leave, from the court before a judicial review application can proceed to a full hearing, which involves a preliminary application demonstrating that the applicant has an arguable case with a realistic prospect of success on at least one of the recognised grounds.
The leave application is generally made on the basis of supporting affidavits and a statement setting out the grounds relied upon, and the court considers this initial application, typically without a full oral hearing at this preliminary stage, to filter out applications that are clearly unmeritorious before committing court and party resources to a full hearing.
If leave is granted, the matter proceeds to a substantive hearing, at which the court considers the merits of the application in full, generally with both parties presenting evidence and legal argument, and if leave is refused, the applicant may in some circumstances seek to appeal that refusal.
Because the leave requirement and its associated procedural steps involve specific technical requirements, anyone considering judicial review should engage a lawyer experienced in this area to prepare and file the application, since a procedurally deficient application risks being refused leave regardless of its underlying merits.
What time limits apply to a judicial review application?
Judicial review applications in Singapore are generally subject to a requirement that the application be made promptly, and in any event within a prescribed period from when the grounds for the application first arose, reflecting the public interest in administrative decisions not remaining open to challenge indefinitely.
The court retains some discretion regarding delay, and may in appropriate circumstances still consider an application made outside the strict time limit where there is a good reason for the delay, though applicants should not rely on this discretion being exercised in their favour and should instead treat the time limit as a firm deadline.
Because the clock generally starts running from when the applicant first knew, or reasonably should have known, of the decision or ground for challenge, applicants should not delay in seeking legal advice once they become aware of a potentially challengeable decision, since time spent considering options can itself erode the time available to file a compliant application.
Because missing the applicable time limit can be fatal to an otherwise valid judicial review application, and because the specific time limit and how it is calculated can involve technical considerations, anyone considering judicial review should seek legal advice immediately upon becoming aware of a potentially challengeable government decision, rather than waiting until they have more fully decided whether to proceed.
Can the challenged decision be suspended while the case is pending?
An applicant for judicial review can apply for a stay of the challenged decision, which would suspend its effect while the judicial review proceedings are ongoing, though this is not automatically granted and the court has discretion to decide whether a stay is appropriate based on the specific circumstances of the case.
In deciding whether to grant a stay, the court generally considers factors such as the strength of the applicant’s case, the harm the applicant would suffer if the decision is not suspended pending the outcome, and the public interest in the decision taking effect, including any impact on third parties or the broader public if the decision is suspended.
Where a stay is refused, the challenged decision generally continues to have effect while the judicial review proceedings are ongoing, which can create significant practical difficulty for an applicant if the proceedings take a considerable time to resolve, particularly for decisions with an immediate and significant practical impact.
Because obtaining a stay involves persuading the court to exercise its discretion in the applicant’s favour based on the specific facts, and because the practical consequences of not obtaining a stay can be significant, applicants who consider a stay important to their situation should raise this at the earliest possible stage and seek legal advice on the prospects of success.
What evidence and affidavits are usually required?
Judicial review applications are generally supported by affidavit evidence rather than oral witness testimony, meaning the applicant sets out the relevant facts and grounds for the application in a sworn written statement, supported by relevant documents such as correspondence with the public body and any decision letter being challenged.
The public body whose decision is being challenged typically files its own affidavit in response, setting out its account of the decision making process and responding to the grounds raised by the applicant, and this exchange of affidavits generally forms the primary evidential basis on which the court determines the application.
Because judicial review proceedings generally focus on the legality and fairness of the decision making process rather than re-examining the underlying merits of the decision itself, the evidence required is generally more limited in scope than in many other types of civil proceedings, though it still needs to be prepared carefully to properly establish the grounds relied upon.
Because the affidavit evidence prepared at the outset of a judicial review application generally forms the core evidential record for the entire proceedings, applicants should ensure their affidavit is thorough and properly prepared with the assistance of a lawyer from the outset, rather than treating it as a preliminary document that can be substantially supplemented later.
What remedies can the court grant?
A quashing order, which invalidates the challenged decision, is one of the primary remedies available in judicial review, and where granted, typically requires the original decision maker to reconsider the matter properly in accordance with the court’s findings, rather than the court itself substituting its own decision on the merits.
A prohibiting order can be granted to prevent a public body from acting in a particular way, while a mandatory order can require a public body to perform a specific duty it has failed to carry out, and both remedies are used to compel a public body to act, or refrain from acting, in accordance with its legal obligations.
A declaration, setting out the court’s view on the legal position without a coercive order, can also be granted, which can be useful for clarifying legal uncertainty even where a more direct remedy is not sought or appropriate given the specific circumstances of the case.
Because the available remedies are generally aimed at correcting the legality of the decision making process rather than directly substituting the court’s own view of the correct outcome, applicants should have realistic expectations about what judicial review can achieve, and a lawyer can advise on the most appropriate remedy to seek given the specific grounds and circumstances of the case.
Can a judicial review decision be appealed?
A decision of the General Division of the High Court in a judicial review application can generally be appealed to the Court of Appeal, Singapore’s highest court, subject to the usual rules and procedures governing appeals from the High Court, including applicable time limits for filing the appeal.
Where leave to apply for judicial review is refused at the initial stage, the applicant may in some circumstances be able to appeal that refusal, though the specific procedure and prospects for such an appeal depend on the particular circumstances and reasons for the refusal.
An appeal to the Court of Appeal generally involves a review of whether the High Court correctly applied the relevant legal principles to the facts, rather than a completely fresh hearing of the matter, and the Court of Appeal’s decision on a judicial review appeal is generally final, subject to very limited further avenues of challenge.
Because pursuing an appeal involves its own specific procedural requirements and additional time and cost, parties considering whether to appeal a judicial review decision, whether the original applicant or the public body whose decision was under challenge, should seek legal advice on the merits and practical considerations involved before deciding whether to proceed.
