Contemporaneous Reasons Required in Brexit-Derived Residence Revocations: New Rationales Cannot Be Supplied in Litigation, and Futility Is Narrow

1) Introduction

In Tahir and Anor v Minister For Justice, Home Affairs and Migration (Rev1) [2026] IEHC 351, the High Court (Simons J) quashed a decision affirming the revocation of a third-country national spouse’s EU/Withdrawal Agreement-linked residence card.

The applicants were a married couple: the husband (a UK national) and the wife (a Moroccan national), with minor children. The wife’s residence card had been issued pre-Brexit on the basis of a derived right of residence under Directive 2004/38/EC as the spouse of an EU citizen (the husband, at the time).

After leaving Ireland in March 2020 and returning in November 2021 (an absence of roughly 20 months), the Minister proposed and then decided to revoke the wife’s residence card. On review, the Minister affirmed revocation by decision dated 17 September 2024. The central issues before the High Court were:

  • whether the review decision complied with the duty to give adequate reasons; and
  • whether relief should be refused as futile (even if reasons were inadequate), based on an asserted “continuity of residence” bar under the Withdrawal Agreement regime.

2) Summary of the Judgment

The High Court granted certiorari quashing the review decision and directed reconsideration under Order 84, rule 27(4) RSC.

The Court held:

  • The impugned decision breached the duty to give reasons, chiefly because the Minister’s “primary reason” relied on in judicial review—an alleged irreversible loss of Withdrawal Agreement protection due to absence exceeding 12 months—did not feature in the revocation process or the decision’s stated reasoning.
  • Separately, the decision failed on “conventional” adequacy grounds: it was internally inconsistent as to when rights ceased; it conflated distinct legal findings (present vs historical exercise of Treaty rights); it largely recited evidence rather than explaining how it was evaluated; and it stated (without reasoning) that the family’s “main centre of interest” was in the UK.
  • The Court rejected the Minister’s argument that relief should be refused as futile. The asserted legal bar was a contestable interpretation of the Withdrawal Agreement and potentially fact-sensitive in application; moreover, allowing an undisclosed litigation rationale to sustain an invalid decision would undermine administrative discipline.

3) Analysis

3.1 Precedents Cited

(a) Connelly v. An Bord Pleanála [2018] IESC 31, [2021] 2 IR 752

The Court applied Connelly to frame the dual function of reasons: (i) enabling the affected person to know why the decision was made, and (ii) enabling an informed decision on appeal/judicial review and facilitating effective court supervision. Simons J emphasised Connelly’s “middle ground”: reasons need not be judicial-style judgments, but must go beyond a perfunctory recital.

(b) Balz v. An Bord Pleanála [2019] IESC 90, [2023] 3 IR 751, [2020] 1 ILRM 367

The Court relied on Balz for the proposition that a decision-maker must address principal, relevant submissions and explain why they are not accepted. Here, the applicants advanced a detailed account explaining absence (housing crisis, emergency accommodation, pandemic lockdowns, pregnancy/health issues, children stranded abroad, storage of belongings in Ireland), and substantial post-return evidence of residence (tenancy, utilities, banking, school enrolment, social welfare, employment). The impugned decision largely quoted/recited this material but did not grapple with its substance.

(c) H.A. v. Minister for Justice [2022] IECA 166

H.A. governed the Minister’s plea to refuse relief on futility. Simons J adopted the Court of Appeal’s insistence on discernible caution: relief should not be refused unless it is very clear that the applicant could not benefit. The onus lies on the party asserting futility; courts must respect the statutory allocation of decision-making to the designated decision-maker; and where the point is arguable (especially where facts/evaluation may matter), remittal is ordinarily appropriate.

3.2 Legal Reasoning

(a) The “new primary reason” problem: reasons must be contemporaneous

A decisive feature was the Minister’s litigation position that the Withdrawal Agreement imposes a “cardinal condition” of continuity of residence; that a single permitted 12-month absence implies that longer absences necessarily break continuity; and that once broken, Withdrawal Agreement-based residence rights cannot be revived by return.

The Court did not finally determine that Withdrawal Agreement interpretation. Instead, it held that—even if correct—it could not cure an inadequate-reasons decision because the impugned decision:

  • did not identify “continuity of residence” as the operative legal test;
  • did not explain the Withdrawal Agreement analysis said to be decisive; and
  • read as a whole, looked like an ordinary 2015 Regulations analysis, not a distinct Brexit/Withdrawal Agreement analysis.

The belated disclosure of the purportedly primary rationale, in response to judicial review, was itself a breach of the duty: reasons exist to allow the recipient to understand the decision and consider challenge at the time it is made.

(b) Internal inconsistency and failure to identify the operative factual/legal basis

The Court identified three different dates used without explanation:

  • March 2020 (departure from Ireland / cessation of exercising rights);
  • 16 October 2020 (the wife’s UK EU Settlement Scheme application—mistakenly treated as a cessation marker in earlier reasoning); and
  • 30 November 2022 (the date the Minister’s first-instance revocation decision issued, and the effective date used in the review decision’s operative outcome).

This left the applicants and the Court unable to determine whether revocation was treated as retrospective or prospective, and what event legally triggered loss of entitlement.

(c) Conflation of “is not exercising” with “has never exercised” Treaty rights

The impugned decision stated the Minister was “not satisfied” the husband “is or has been” exercising EU Treaty rights. Simons J treated this as a legally significant conflation: a present failure and a historical failure are different findings with different legal consequences. The decision also recited earnings and employment post-return, creating an unresolved tension between the evidence listed and the conclusion announced.

(d) Recital of evidence is not reasoning; “centre of interest” needed explanation

The decision set out extensive material (tenancy, utility bills, bank statements, children’s schooling, social welfare, employment), but failed to explain what weight was attached or why it was insufficient. The stated conclusion that the family’s “main centre of interest” was in the UK appeared to rely heavily on travel in early 2022, without explaining why that travel outweighed other indicators of day-to-day residence in Ireland.

3.3 Impact

  • Immigration and Brexit-related residence decisions: where Withdrawal Agreement concepts (such as “continuity of residence”) are material, the decision-maker must identify and apply that framework expressly and explain the consequences for the individual. A generic EU free movement-style analysis may be inadequate where the post-Brexit legal architecture differs.
  • Administrative law discipline: the judgment reinforces that the duty to give reasons is not satisfied by lengthy narration. It requires evaluative explanation—especially when rejecting a supported, specific case.
  • Limits on “futility”: public bodies will face difficulty resisting certiorari by advancing a new, decisive legal theory in litigation that was not presented to the affected person or reflected in the decision. The Court emphasised that permitting this would erode the reasons requirement and risk transforming judicial review into a merits forum.

4) Complex Concepts Simplified

  • Derived right of residence: a family member’s residence right that exists because (and only so long as) the qualifying Union citizen (or protected person) has the relevant residence status in the host state.
  • Residence card is “declaratory”: it evidences a status/right that exists by law; it does not, by itself, create the underlying right.
  • Withdrawal Agreement “continuity of residence”: for UK nationals/families protected after Brexit, eligibility can depend on whether residence in the host state continued across the transition end. The Agreement cross-refers to EU free movement rules on permissible absences.
  • Duty to give reasons: reasons must allow the affected person to understand why they lost and allow a court to review legality. A decision that merely lists evidence and states a conclusion, without bridging the gap, is vulnerable.
  • Futility discretion: exceptionally, a court may refuse to quash an unlawful decision if it is very clear no different lawful outcome is possible. The threshold is high and applied cautiously.
  • Carltona principle: permits a Minister’s statutory functions to be performed by authorised officials acting in the Minister’s name.

5) Conclusion

[2026] IEHC 351 stands as a pointed restatement that administrative decisions—particularly in legally complex, post-Brexit residence contexts—must disclose their true legal and factual basis at the time they are made. A public authority cannot cure an inadequate decision by unveiling a new, allegedly decisive rationale in judicial review proceedings, nor can it readily invoke “futility” to preserve a decision that is unlawful for want of reasons. The matter was remitted for a fresh decision containing an adequate statement of reasons.
