Strict Limits on Costs for Unsuccessful Public-Interest Appellants in Statutory-Interpretation Appeals

1. Introduction

This ruling concerns costs following the Supreme Court’s substantive judgment in Chain Wen Wei -v- The Minister for Justice & ors (see: [2024] IESC 58), in which the Court dismissed the appellants’ appeal. The underlying litigation arose from decisions of the immigration authorities refusing the appellants permission to land or be in the State under s.4 of the Immigration Act, 2004.

The appellants had unsuccessfully sought judicial review in the High Court (Burns J., 23 March 2021), and then unsuccessfully appealed to the Court of Appeal (2 June 2023), before their further appeal to the Supreme Court failed. The present ruling addresses whether, notwithstanding their lack of success, the appellants should receive some portion of their own costs (or whether the respondents should be deprived of costs), given the public importance of the issues argued.

The core issue was the proper approach to awarding costs (or a portion of costs) to an unsuccessful party in litigation said to have a public-interest dimension—particularly where the case involved statutory interpretation and clarified prior uncertainty.

2. Summary of the Judgment (Costs Ruling)

The Supreme Court applied the principles recently set out in Little v The Chief Appeals Officer & Ors (No.2) [2024] IESC 53. It held that, although the appeal involved a matter of general public importance and clarified the meaning of “public policy” in the relevant immigration context, it was not the type of rare/exceptional case in which the taxpayer should bear any part of the unsuccessful appellants’ costs.

The Court concluded that the appeal: (a) concerned the application of well-established principles of statutory interpretation to the 2004 Act; (b) did not directly raise constitutional or European law issues; (c) was not “foundational” in the relevant sense; and (d) was pursued for the appellants’ personal advantage.

Accordingly, the Court made the costs orders proposed by the respondents: (i) no order as to costs in the Supreme Court appeal; and (ii) on consent, setting aside the respondents’ costs orders in the High Court and Court of Appeal and substituting no order as to costs at those levels.

3. Analysis

3.1 Precedents Cited

3.1.1 Little v The Chief Appeals Officer & Ors (No.2) [2024] IESC 53 (“Little (No. 2)”)

Little (No. 2) was central. The Court treated it as the governing modern statement on when an unsuccessful litigant might nonetheless obtain an award of costs in public-interest-type litigation. The ruling in the present case closely tracked Murray J.’s reasoning in Little (No. 2), including the emphasis that awarding costs to an unsuccessful party is subject to a stricter test than merely relieving that party from an adverse costs order.

The Supreme Court adopted the approach that such awards are typically confined to cases involving foundational constitutional or European law issues, or other exceptional categories. It also adopted the key evaluative considerations identified in Little (No. 2): whether the case is personal-interest driven, whether it turns on ordinary statutory interpretation, and whether it raises legal questions of sufficient significance/strength to justify taxpayer-funded costs.

3.1.2 Collins v. Minister for Finance [2014] IEHC 79 (“Collins”)

The parties relied on Collins for its taxonomy of situations where courts have previously awarded costs to unsuccessful parties. In this ruling, the Supreme Court treated the Collins categories (as later supplemented in Little (No. 2)) as an organising framework, not as a checklist automatically satisfied by “public importance” alone. The Court ultimately held the present case did not fit within those categories.

3.1.3 Dunne v. The Minister for the Environment [2008] 2 I.R. 775

The respondents invoked Dunne as part of the lineage of Irish costs jurisprudence in public law and public interest litigation. While the Court did not restate Dunne at length, it accepted (via Little (No. 2)) that later case law has applied a far stricter test when the question is whether the unsuccessful party should receive their own costs from the State.

3.1.4 Ezenwaka v. Minister for Justice, Equality and Law Reform [2011] IEHC 328 and Li and Wang v. Minister for Justice and Equality [2015] IEHC 638

These High Court decisions were cited by the appellants to demonstrate divergent interpretations of “public policy” in the immigration/refusal-of-entry context. The appellants argued that their appeal served the public interest by resolving that divergence. The Supreme Court accepted that there had been uncertainty and that its substantive judgment clarified the law, but held that clarification of this type, standing alone, does not make a case sufficiently exceptional to justify an award of costs to an unsuccessful party.

3.1.5 Ononkewagbe v Governor of the Dóchas Centre and the CFA [2017] IEHC 243

The appellants relied on Ononkewagbe as an example where partial costs were awarded to applicants because an aspect of the decision had general application and benefited the State’s law enforcement agencies, and because statutory provisions were interpreted for the first time. The Supreme Court implicitly distinguished that situation: here, the appeal was characterised as an application of established interpretive tools rather than a first-time construction of a statutory regime in circumstances warranting a taxpayer-funded costs award to the losing side.

3.1.6 The substantive Supreme Court decision: [2024] IESC 58

This costs ruling is parasitic on the outcome and nature of the substantive appeal. Although the costs decision does not rehearse the full merits, it treats the appeal’s character—principally statutory interpretation of the Immigration Act 2004 and associated concepts—as decisive against awarding the appellants any portion of their costs.

3.2 Legal Reasoning

The Court’s reasoning proceeds in three structured steps:

  1. Identify the controlling principles: the Court treated Little (No. 2) as the most recent authoritative guide to costs for unsuccessful public-interest litigants, including the refined and restrictive approach to awarding costs in favour of an unsuccessful party.
  2. Locate the case within (or outside) recognised exceptional categories: the Court set out the Collins categories and the additional category identified in Little (No. 2):
    • fundamental constitutional issues touching sensitive aspects of the human condition;
    • conspicuously novel constitutional/separation-of-powers issues;
    • issues of far-reaching importance in an area of general application;
    • clarifying an obscure or unexplored area; and
    • cases where the claimant loses overall but wins a significant issue on appeal.
    The Court concluded the case did not qualify under these headings at the level required to justify taxpayer-funded costs for the losing party.
  3. Apply the “Little (No. 2)” evaluative factors: mirroring Murray J.’s approach, the Court emphasised that this was (i) statutory interpretation using established principles, (ii) not constitutional/European/foundational, (iii) pursued for personal advantage, and (iv) although of general importance, not of such significance/strength that the taxpayer should pay the appellants’ costs.

Importantly, the Court drew a clear line between: (a) acknowledging public importance (a common feature of Supreme Court appeals), and (b) treating that importance as sufficient to justify an affirmative costs award to an unsuccessful party. The former does not entail the latter.

The respondents’ reference to ss. 168 and 169 of the Legal Services Regulation Act, 2015 was used to support the proposition that a “no order as to costs” outcome can be an appropriate and proportionate response—recognising the nature of the issues without crossing the high threshold for compensating a losing party from public funds.

3.3 Impact

The ruling consolidates a clear practical message for Irish public law litigation, including immigration judicial review:

  • Public importance is not enough: even where an appeal is certified/admitted on grounds of general public importance and clarifies inconsistent High Court authority, the Court may still refuse any award of costs to an unsuccessful party.
  • “Foundational” remains a gatekeeper concept: absent constitutional or European law dimensions (or similarly exceptional features), the Court is unlikely to require the State to fund the unsuccessful litigant’s costs.
  • “No order as to costs” is a middle position: the Court endorsed an outcome where neither side recovers costs (including by setting aside costs orders below on consent), which can reduce the chilling effect of adverse costs without affirmatively subsidising losing litigation.
  • Costs strategy in test cases: parties contemplating “test case” litigation should not assume that clarifying statutory meaning (even where prior jurisprudence diverged) will yield a costs recovery if they lose; they must demonstrate a higher-order public interest of the kind mapped in Collins and Little (No. 2).

4. Complex Concepts Simplified

  • “No order as to costs”: each party bears its own legal costs; neither side can recover costs from the other.
  • Public interest litigation (in costs terms): cases argued as serving a wider public benefit beyond the parties. Irish courts may sometimes protect such litigants from paying the State’s costs, but awarding the litigant their own costs despite losing is much rarer and requires exceptional justification.
  • “Foundational” issues: issues of deep constitutional or European law significance (e.g., structure of government powers, fundamental rights) that justify exceptional costs treatment because the litigation materially develops the legal framework.
  • Certified “point of law of exceptional public importance” / Supreme Court admission: signals that an appeal warrants Supreme Court consideration; it does not automatically alter the ordinary approach to costs.
  • noscitur a sociis: an interpretive maxim meaning a word’s meaning can be informed by the surrounding words. The appellants argued the appeal clarified its parameters, but the Court treated this as part of ordinary statutory interpretation, not an exceptional basis for a costs award.

5. Conclusion

The Supreme Court’s costs ruling reinforces a strict, modern approach: an unsuccessful appellant will not receive an award of costs merely because their case raised issues of general public importance or clarified inconsistent lower-court interpretations. Applying Little v The Chief Appeals Officer & Ors (No.2) [2024] IESC 53 and the categories discussed in Collins v. Minister for Finance [2014] IEHC 79, the Court held this appeal was essentially an exercise in established statutory interpretation pursued for personal advantage, lacking the “foundational” quality required to justify shifting the appellants’ costs onto the taxpayer.

The practical significance lies in the Court’s endorsement of “no order as to costs” as an appropriate resolution in some public-law appeals—while maintaining a high threshold for any affirmative costs award to the losing party.
