Judicial Review as a Remedy of Last Resort: Default Duty to Exhaust Adequate Statutory Remedies (Including Social Welfare s. 318 Revision)

Case: L.A. v The Chief Appeals Officer & Ors (Approved)
Citation: [2026] IESC 22 (Supreme Court of Ireland, Donnelly J.)
Date: 25 March 2026

1. Introduction

This decision concerns the interaction between judicial review and the “revision/appeals” machinery in Part 10 of the Social Welfare (Consolidation) Act, 2005 (“the 2005 Act”). The appellant, Lacramioara Amariei (named despite earlier anonymisation at lower levels), challenged a refusal of disability allowance. After an adverse decision by a deciding officer, an appeal was determined by an appeals officer (s. 311), and the appellant then sought a review by the appeals officer under s. 317. When that s. 317 review did not succeed, she brought judicial review against the refusal.

The central issue—identified in the determination granting leave to appeal—was:

The Supreme Court used the appeal to restate and systematise Irish law on the exhaustion of adequate alternative remedies, with particular focus on what applicants must show at the leave stage and how that doctrine applies to the social welfare scheme—especially the s. 318 revision by the Chief Appeals Officer.

2. Summary of the Judgment

• The Court reaffirmed that judicial review is discretionary and ordinarily will not be available where an adequate alternative remedy exists.
• Building on EMI Records v Data Protection Commissioner [2014] 1 ILRM 225, [2013] IESC 34, the Court held the default position is that applicants must pursue and exhaust adequate alternative statutory remedies (appeals or reviews) before judicial review.
• The Court set out a consolidated set of principles (at para. [105]) covering: the default rule; its multi-factor rationale; narrow exceptions; onus; and the leave-stage test.
• Applying those principles to Part 10 of the 2005 Act, the Court held that s. 318 (revision by the Chief Appeals Officer for “mistake… in relation to the law or the facts”) is an adequate alternative remedy that must be exhausted before judicial review will lie (absent exceptional circumstances).
• The Court stated that, insofar as T v Minister for Social Protection [2023] IEHC 763 suggested a claimant could proceed by judicial review notwithstanding s. 327 (and without exhausting s. 318), it was wrong.
• The appeal was dismissed because the appellant had not exhausted the adequate alternative remedy under s. 318.
• On open justice, the Court refused to continue anonymity: s. 27 of the Civil Law (Miscellaneous Provisions) Act, 2008 was not engaged on the facts as presented, and no formal application had been made.

3. Analysis

3.1. Precedents Cited

A. The foundational Irish authority: “adequate alternative remedy” and discretion

• The State (Abenglen Properties) v Corporation of Dublin [1984] IR 381 (“Abenglen”)
  The judgment traces the doctrine’s modern Irish shape to Abenglen, especially O’Higgins CJ’s well-known passage (p. 393) stressing that the existence of a right of appeal does not automatically bar certiorari, but that courts should be “slow” to quash where statutory appeal machinery is “adequate”. Donnelly J. emphasises that Abenglen is not a bright-line rule; however, it catalysed the modern “exhaustion” orientation and the conception of self-contained statutory codes with court intervention only exceptionally.
• G v Director of Public Prosecutions [1994] 1 IR 374
  Used for the leave-stage test. Finlay CJ’s requirement that an applicant must show judicial review is the “only effective remedy” or that judicial review is “more appropriate” anchors Donnelly J.’s modernised statement: at leave, the applicant must establish arguable (or substantial) grounds that they fall within a narrow exception to the default exhaustion rule.
• Kelly v Minister for Agriculture [2023] 1 IR 38, [2021] IESC 62 and Christian v Dublin City Council [2012] 2 IR 506, [2012] IEHC 163
  Cited to define the nature of judicial discretion: it is constrained and cannot be used to reflect a court’s view of the underlying merits; any departure from granting relief otherwise justified must be grounded in constitutional/legal values of sufficient weight.

B. The doctrinal “pivot”: default position that statutory routes should be used

• EMI Records v Data Protection Commissioner [2014] 1 ILRM 225, [2013] IESC 34 (“EMI”)
  Central to this decision. Donnelly J. treats EMI as clarifying and transforming the law by stating expressly that the default position is to pursue statutory appeals rather than judicial review. The Court extends that logic beyond court-appeals to statutory administrative appeal/review structures generally.
• Koczan v Financial Services Ombudsman [2010] IEHC 407 (“Koczan”)
  Adopted (via EMI) for the proposition that the Oireachtas, in creating an appeal, generally intends it to be the ordinary vehicle for ventilating complaints, with judicial review reserved for exceptional categories (e.g., total lack of jurisdiction, basic fairness, constitutional validity).
• Petecel v Minister for Social Protection [2024] 2 IR 685, [2020] IESC 25
  Used as an example of a rare exception: where internal social welfare mechanisms could not decide the validity/classification issue raised (EU-law related), the default exhaustion requirement yielded.
• Habte v Minister for Justice [2021] 3 IR 627, [2020] IECA 22 (“Habte”)
  Quoted for a crisp Court of Appeal articulation: relief should be refused unless the alternative remedy is not adequate, or there is “a particular exigency in the interests of justice”.

C. Breadth of “appeal on a point of law” and overlap with judicial review

• Castleisland Cattle Breeding v Minister for Social Welfare [2004] 4 IR 150, [2004] IESC 40
  Addressed because it contained obiter comments suggesting the predecessor of s. 318 was “revising rather than appellate”. Donnelly J. treats those comments as non-determinative, and reads later authority (notably McDonagh v Chief Appeals Officer) as supporting a more integrated and claimant-beneficial understanding of the revision/appeal code.
• McDonagh v Chief Appeals Officer [2021] ILRM 385, [2021] IESC 33 (“McDonagh”)
  Important to the interpretive method: Part 10 is “generous and flexible”, revision provisions are wide, and “a decision not to revise is a decision”. Donnelly J. uses McDonagh to support the view that s. 318 is a meaningful, integrated remedy within the statutory machinery (and also to support a practical, sensible construction of “revised decision”).
• Attorney General v Davis [2018] 2 IR 357, [2018] IESC 27
  Used to describe the expansive content of a “point of law” appeal: not only pure legal errors but also judicial review-type errors (illegality, irrationality, defective reasoning, significant procedural errors), and certain fact-errors that amount to legal error. This undercuts any argument that statutory point-of-law appeals are necessarily too narrow to be “adequate”.
• Orange Ltd v Director of Telecoms (No 2) [2000] 4 IR 159, [2000] IESC 22
  Cited as an example of a statutory appeal extending to fair procedures issues.

D. Earlier procedural-fairness and “appeal vs certiorari” tensions

Donnelly J. gives a historical account (pre-Abenglen) to show why the doctrine evolved: growing administrative decision-making; expanding judicial review; and pressure on courts.

• Ingle v O'Brien (1975) 109 ILTR 7, Leary v National Union of Vehicle Builders [1971] 1 Ch 34 (“Leary”), and Moran v Attorney General [1976] IR 400
  These reflect an earlier tendency to treat a natural justice breach at first instance as not curable by an appellate sufficiency, drawing on Megarry J.’s statements in Leary.
• Calvin v Carr [1980] AC 574
  Referenced to show the retreat from any absolute Leary-style rule, at least in the Privy Council’s contractual-procedure context.
• The State (Stanbridge) v Mahon [1979] IR 214, State (Roche) v Delap [1980] IR 170, and R (Miller) v Justices of Monaghan (1906) 40 ILTR 51
  Used to illustrate circumstances where courts refused certiorari because appeal (especially de novo appeal) could correct the defect, including the proposition that certiorari does not lie while an appeal is pending.

E. Social welfare and related administrative review authorities

• FD v Chief Appeals Officer [2023] IECA 123
  Used as a modern social welfare example: the Court of Appeal required exhaustion of s. 317 revision; Donnelly J. reiterates the breadth and (possibly unique) flexibility of Part 10 revision provisions.
• AM v Minister for Social Protection [2013] IEHC 524
  Cited for the proposition that s. 311 de novo appeal is an alternative remedy that ordinarily must be used.
• Maher v Minister for Social Welfare [2008] IESC 15
  Cited on (limited) circumstances where lack of clear information about remedies may make it unfair to insist on exhaustion—especially for lay litigants seeking guidance. Donnelly J. treats it as fact-specific and declines to decide broader notification obligations on the record before her.
• Little v Chief Appeals Officer [2023] IESC 25 (“Little”)
  Cited for the approach to remedial interpretation: Part 10 procedural provisions should be read as widely as reasonably possible.

F. UK and ECHR comparators on “JR last resort” and burden

• R (Glencore Energy UK Ltd) v Revenue and Customs Commissioners [2017] 4 WLR 213, [2017] EWCA Civ 1716 and Re McAleenon [2025] AC 1362, [2024] UKSC 31
  Cited to support the proportional allocation of judicial resources rationale: treating judicial review as a last resort preserves the High Court’s capacity to act as protector of the rule of law where intervention is truly required.
• Gherghina v Romania (2015) 61 EHRR SE15 (“Gherghina”)
  Considered by analogy on burden of proving exhaustion, but distinguished: the ECtHR’s approach is shaped by its supervisory/international role and the need for states to explain their domestic remedies. Donnelly J. rejects importing that burden model into Irish leave-stage practice.

3.2. Legal Reasoning

A. The doctrinal core: default rule, narrow exceptions, and structured discretion

The Court’s primary legal move is to harmonise older “discretion” language (which sometimes sounded like courts simply “weighing” remedies) with the more structured approach in EMI. Discretion remains, but it is not free-ranging: it is bounded by constitutional values (open justice, rule of law) and by legal values (legislative intent, suitability of statutory schemes, proportional use of court resources).

The Court identifies the “multifaceted” rationale for exhaustion (paras. [49]–[58]) and uses it to justify a strong starting presumption:

• Legislative intent: where the Oireachtas creates tailored routes of correction, courts should generally require them to be used.
• Institutional competence: specialist bodies may address matters more fully than judicial review can.
• Judicial resources and timeliness: courts must remain available for cases that truly require judicial review intervention.
• Cost and delay: avoiding unnecessary litigation benefits claimants and the public purse.

Against that, the Court preserves a safety valve: judicial review can proceed where the alternative is not in fact adequate, or where there is “a particular exigency in the interests of justice” (Habte). Importantly, “adequacy” is not assessed by asking whether judicial review is “better” for the applicant; it is assessed by asking whether the statutory route can fairly and effectively ventilate and remedy the complaint, having regard to the role of judicial review and the statutory design.

B. Onus and the leave-stage test (a significant practical holding)

A key operational aspect is the Court’s insistence that exhaustion must be confronted at the leave stage. Drawing on G v Director of Public Prosecutions, the Court holds:

• The applicant must address whether an alternative remedy exists and, if so, why the case fits within an exception.
• The court may refuse leave or adjourn under Order 84, rule 20(6) to allow an appeal to run or the appeal time to expire.
• Where an adequate alternative remedy is clear on the law, the applicant must show arguable/substantial grounds that the case is exceptional; otherwise, the leave threshold is not met because the court’s discretion would “only be exercised to refuse” judicial review even taking the case at its highest.

The Court places the onus squarely on the applicant, distinguishing the ECtHR approach in Gherghina. The applicant is best positioned to plead and evidence why the statutory route is inadequate in their circumstances.

C. Application to Part 10 of the 2005 Act: why s. 318 is “adequate”

The Court’s statutory analysis rejects the characterisation of s. 318 as a mere residual “own motion” backstop outside the appeals scheme. Instead, s. 318 is read as an integral part of the “generous and flexible” remedial code, filling a deliberate gap:

• s. 317 revision by an appeals officer is confined to new facts/evidence or change of circumstances; it does not cover “mistake in relation to the law or the facts”.
• s. 318 assigns “mistake of law or fact” revision power to the Chief Appeals Officer, thereby creating a targeted, internal correction mechanism capable of engaging “almost any issue of fact or law” (a conclusion aligned with the Court of Appeal’s assessment).

Donnelly J. treats the s. 318 route as (i) wide enough to remedy the appellant’s complaints, (ii) quicker and cheaper than court proceedings, and (iii) consistent with the public interest and legislative design that Part 10 be used as the primary channel. Because the appellant did not invoke s. 318, she did not overcome the default position; thus, judicial review “ought to have been refused”.

D. Relationship with s. 327 (appeal on a point of law)

While the Court did not need to decide the case on s. 327, it addresses the appellant’s argument that overlap between judicial review grounds and s. 327 meant she should not be “penalised” for selecting judicial review. The Court rejects that framing: the overlap reinforces, rather than weakens, the case for treating s. 327 as an adequate alternative remedy in ordinary circumstances. It also expressly notes the broad reach of point-of-law appeals (citing Attorney General v Davis and the social welfare line including Castleisland Cattle Breeding v Minister for Social Welfare, Petecel v Minister for Social Protection, and McDonagh v Chief Appeals Officer).

E. Open justice and anonymity

The Court’s anonymity discussion is a separate, practical public-law holding: anonymity orders are exceptions to Article 34 open justice and must be justified within statutory limits. Here, although the High Court anonymised the appellant under s. 45 of the Courts (Supplemental Provisions) Act, 1961, Donnelly J. concluded that s. 27 of the Civil Law (Miscellaneous Provisions) Act, 2008 was not properly invoked on the record: no formal application was made and the judgment did not identify a specific medical condition such that identification would link her to “that condition”.

3.3. Impact

• Consolidation and operationalisation: The judgment is likely to be treated as a leading modern statement of the “exhaustion of remedies” doctrine in Ireland, not only in social welfare but across administrative law, because it synthesises rationale, default rule, exceptions, and the leave-stage burden into a single set of principles (para. [105]).
• Higher bar at leave stage where remedies exist: Applicants must now explicitly plead and evidence why they fall within an exception. A failure to engage with available statutory routes (especially clearly identified ones) should more often result in refusal of leave or adjournment.
• Social welfare litigation channelled back into Part 10: The decision strengthens the expectation that claimants use s. 318 for alleged mistakes of law/fact in appeals officer decisions, and reserves judicial review for genuinely exceptional cases (e.g., issues that the statutory bodies cannot decide, as in Petecel v Minister for Social Protection).
• Reduced reliance on T v Minister for Social Protection: The Supreme Court’s statement that Heslin J. was in error on the availability of judicial review in the face of s. 327 will diminish that case’s practical utility for bypassing statutory routes.
• Anonymity discipline: Litigants cannot assume continued anonymisation merely because it occurred below; a proper statutory basis and application is required, and courts will scrutinise whether publication would in fact identify a person as having a particular medical condition.

4. Complex Concepts Simplified

• Judicial review vs appeal: An appeal typically reassesses correctness (sometimes facts); judicial review assesses legality (powers, procedures, rationality), not merits.
• Certiorari: A judicial review remedy quashing an unlawful decision.
• Exhaustion of alternative remedies: If the law provides another effective way to correct the problem (appeal/review), courts usually require it to be used first.
• Default position / exceptions: The presumption is “use the statutory route”; judicial review is exceptional where the statutory route is inadequate or justice urgently requires court intervention.
• “Point of law” appeal can be wide: As explained in Attorney General v Davis, it may include many judicial review-type errors and some “fact errors” that are treated as legal errors (e.g., no evidence; irrational findings).
• Own-motion power: A power exercisable without an application. The Court rejected that s. 318 should be understood as only (or mainly) own-motion; it is a remedy claimants can invoke.
• Open justice and anonymity: Courts are generally public; secrecy/anonymity needs a clear legal basis and evidence that statutory conditions are met.

5. Conclusion

L.A. v The Chief Appeals Officer & Ors restates Irish law in a form designed to be applied at the coalface of leave applications. The Supreme Court confirms that judicial review is ordinarily a remedy of last resort: the default position is that litigants must exhaust adequate statutory appeals or reviews, and the onus lies on the applicant to show inadequacy or a justice-based exigency. In the social welfare context, the Court holds that s. 318 is a central, integrated correction mechanism for mistake of law or fact, and that bypassing it will generally bar judicial review.
