Omnibus Hearings and Extension of Time in Immigration Judicial Review: Merits and Post-Leave Conduct as Certifiable Points of Exceptional Public Importance

Introduction

G (Angola) (Leave To Appeal) v International Protection Appeals Tribunal and Anor (Approved) [2026] IEHC 441 is a High Court decision (Simons J) on an application by the Minister for Justice, Home Affairs and Migration for a certificate permitting an appeal to the Court of Appeal under section 5(6) of the Illegal Immigrants (Trafficking) Act 2000.

The underlying judicial review challenged an International Protection Appeals Tribunal (IPAT) refusal of refugee status and subsidiary protection, which turned on an adverse finding as to the applicant’s “general credibility”. The judicial review was commenced outside the statutory time-limit, requiring an extension of time.

The case is procedurally significant because (as is now common in the immigration list) leave was granted without prejudice to time-limit objections, and the extension-of-time issue was determined alongside the substantive judicial review at an omnibus hearing. In the principal judgment, G. (Angola) (Assessment of Credibility) v. International Protection Appeals Tribunal [2026] IEHC 143, the High Court both (i) quashed the IPAT decision for legal error in the approach to credibility and (ii) extended time. The Minister sought to appeal only the extension-of-time aspect.

Summary of the Judgment

The High Court applied the established certification test under section 5(6) (as interpreted through Glancré Teoranta v. An Bord Pleanála (No. 2) [2006] IEHC 250) and:

  • Certified two points of law as involving issues of exceptional public importance where an appeal was desirable in the public interest:
    1. In an omnibus hearing, whether the trial judge must decide the extension of time first without regard to merits, or may treat the judge’s merits conclusion as one factor in “good and sufficient reason”.
    2. In the same setting, whether and how the court may consider the respondent’s post-leave conduct (e.g., late opposition papers) in assessing prejudice and “good and sufficient reason”, having regard to the legislative intent behind the statutory time-limit.
  • Refused certification on other proposed points, characterising them as disagreements with evaluative application of settled principles (e.g., delay by legal advisers; prejudice; and whether the court may consider factors beyond those pleaded on affidavit).

Analysis

Precedents Cited

1) The certification gateway: “exceptional public importance”

  • Glancré Teoranta v. An Bord Pleanála (No. 2) [2006] IEHC 250:

    The court reaffirmed that certification is not a general right of appeal. The point must be a point of law (not merely an alleged error), of exceptional public importance, where clarification yields an affirmative public benefit and helps resolve future cases. Simons J emphasised the “uncertainty” requirement and the need for sparing exercise.

  • Grace v. An Bord Pleanála [2017] IESC 10, [2020] 3 IR 286:

    Used to situate certification within the post-2014 appellate “architecture”: while leapfrog appeal to the Supreme Court exists, appeal to the Court of Appeal should usually be the ordinary route.

  • Pepper Finance Corporation v. Cannon [2020] IESC 2, [2022] 1 IR 128:

    Cited for the proposition that Supreme Court access cannot be restricted by legislation in the way Court of Appeal jurisdiction can be, illustrating why the two routes differ conceptually and procedurally.

2) Extension of time: “good and sufficient reason” as a holistic discretion

  • Thomson v. An Bord Pleanála [2025] IESC 31:

    Central authority for the High Court’s rejection of rigid rules. It confirms a holistic assessment of all relevant circumstances, including explanation for delay, conduct of parties, prejudice (including public interest), finality, and (where appropriate) merits. Simons J relied on this to refuse certification of the Minister’s proposed “affidavit confines the court” point.

  • M O'S v. Residential Institutions Redress Board [2018] IESC 61, [2019] 1 ILRM 149:

    Treated as the closest analogue for when merits may matter: the Supreme Court attributed weight to a respondent’s concession that, if time were extended, the applicant would succeed. Simons J used M O'S to justify (and to identify uncertainty about) whether a trial judge in an omnibus hearing may similarly attribute weight to merits once the judge knows the outcome through adjudication (rather than concession).

  • Arthropharm (Europe) Ltd v. Health Products Regulatory Authority [2022] IECA 109:

    Relied on for the pragmatic “spectrum” approach to merits when time is addressed at an early stage: merits usually matter only at extremes (unarguable or unanswerable), to avoid converting an extension application into a “mini-trial”.

  • Re Article 26 and the Illegal Immigrants (Trafficking) Bill 1999 [2000] IESC 19, [2000] 2 IR 360:

    Used in two ways: (i) by the Minister, to stress that the statutory time-limit serves early certainty enabling implementation of immigration decisions; (ii) by the court, to underline that constitutionality of strict time-limits depended on a sufficiently broad judicial discretion to extend time where justice requires.

  • S. v. Minister for Justice, Equality and Law Reform [2002] 2 IR 163:

    Cited to refute any absolute proposition that solicitor delay can never support an extension; rather, it is generally insufficient “without more”, but may contribute alongside absence of prejudice and other factors.

3) Divergence in High Court practice: omnibus hearings and merits sequencing

  • G.K. v. International Protection Appeals Tribunal [2022] IEHC 204 and M. v. Chief International Protection Officer [2024] IEHC 623:

    These decisions were cited as examples where trial judges, despite hearing full argument on merits, addressed and refused extension of time first without relying on merits (with merits considered de bene esse in G.K.). Simons J treated this as evidence of a real divergence warranting appellate clarification.

Legal Reasoning

1) Why two points were certified

Simons J identified a practical and recurring procedural reality in immigration judicial review: time-limit issues are frequently reserved to the trial judge. That practice creates two unresolved questions with system-wide consequences:

  • Merits in an omnibus hearing: Once a judge has heard and determined the merits, is it legally permissible (or required) to “exclude” that knowledge when deciding “good and sufficient reason”? The court held this was unresolved at appellate level, that it affected many cases, and that the High Court contained divergent approaches.
  • Post-leave respondent conduct: If the trial judge sees the case’s subsequent trajectory (including late pleadings by the respondent), how can that be weighed against the statutory objective of early certainty? The court rejected the Minister’s attempt to confine “conduct” to something approaching misconduct, but accepted that the weight of post-leave delay must be reconciled with the legislative intent of section 5.

These issues were framed as meeting Glancré: genuine uncertainty, exceptional importance, and likely benefit to future case management and outcomes.

2) Why the other proposed points were refused certification

  • Solicitor delay as a “default refusal”:

    The court held there is no legal uncertainty. The law already provides that legal representative delay is generally insufficient without more, but is not an absolute bar. The Minister’s proposed questions were characterised as attempts to appeal an evaluative weighing of factors on the facts, not a point of law of exceptional public importance.

  • Prejudice to the State as automatic:

    The court treated prejudice as part of the holistic balance, not a categorical presumption that delay always prejudices the State. Whether prejudice exists, and its weight, is fact-sensitive; that does not create a certifiable legal uncertainty. (A narrower prejudice-related issue—post-leave conduct—was certified separately.)

  • Confined to factors on affidavit:

    The court held the answer is supplied by Thomson v. An Bord Pleanála [2025] IESC 31: discretion is holistic and not confined to what an applicant pleads; the applicant’s evidential burden is distinct from the court’s evaluative function, which must account for broader public interest and procedural context.

Impact

  • Clarification of omnibus-hearing methodology:

    If the Court of Appeal endorses one approach, it will standardise how trial judges sequence and reason extension-of-time decisions where time issues are reserved, reducing inconsistent outcomes.

  • Role of merits in time extensions:

    The certified question has potential to recalibrate the practical importance of merits where delay is modest but the decision under challenge is unlawful—particularly acute in international protection cases where refusal can have serious consequences.

  • Post-leave conduct and statutory purpose:

    The second certified point may define when respondent delay can be used merely to negate asserted prejudice, versus when it can positively support “good and sufficient reason”, and how that sits with the purpose of early certainty in immigration enforcement.

  • Certification discipline:

    The refusal to certify “fact-weighting” complaints reinforces that section 5(6) is designed to prioritise expedition and finality, allowing appeals only to resolve genuinely uncertain legal questions of broader significance.

Complex Concepts Simplified

  • “Good and sufficient reason”:

    A flexible statutory standard allowing the court to extend a strict time-limit where justice requires, assessed by considering all relevant circumstances rather than any single rigid rule.

  • “Omnibus hearing”:

    A hearing where the court deals with the extension-of-time issue and the substantive judicial review together, rather than deciding time issues at the earlier leave stage.

  • “Merits at the extremes” (the spectrum):

    At an early procedural stage, courts typically avoid deep merits analysis unless the case is plainly hopeless or plainly bound to succeed, because otherwise the time-extension application risks becoming a full trial.

  • Certification under section 5(6):

    An appeal is permitted only if the High Court certifies that the decision involves a point of law of exceptional public importance and that an appeal is desirable in the public interest; it is not a general appeal mechanism for alleged errors on the facts.

Conclusion

[2026] IEHC 441 identifies and certifies two questions of exceptional public importance arising from a now-common procedural choice in immigration judicial review: reserving extension-of-time disputes to the substantive hearing. The judgment’s core contribution is to crystallise an appellate issue about whether, and how, a trial judge may factor in (i) the judge’s own merits determination and (ii) post-leave respondent conduct when deciding “good and sufficient reason” under section 5. At the same time, it reinforces that section 5(6) certification is not a vehicle for appealing discretionary fact-weighting, and it anchors extension-of-time analysis in the holistic methodology confirmed by Thomson v. An Bord Pleanála [2025] IESC 31.
