| RAS Medical Ltd v. Royal College of Surgeons [2019] IESC 4; [2019] 1 IR 63 |
Affidavits must not contain argumentative statements or impermissible post-decision reasoning; deponents should limit themselves to matters within direct knowledge. |
The Court relied on this authority to justify disregarding elements of the Respondent's affidavit that strayed into post-decision reasoning or opinion and matters not within the deponent's direct knowledge. |
| R v. Westminster City Council Ex parte Ermakov [1996] 2 All ER 30 |
Post-decision rationalisations are impermissible; a court should confine review to reasons stated on the face of the decision. |
The Court applied the principle to exclude ex post facto explanations and to disregard affidavit material amounting to post-decision reasoning. |
| City of Waterford VEC v. Secretary General of the Department of Education and Science & ors [2011] IEHC 278 |
Approving the restriction on post-decision rationalisation and the need to confine review to reasons given. |
Used by the Court as supporting authority for disregarding post-decision rationalisations in the Respondent's affidavit. |
| TAR & anor v. Minister for Justice [2014] IEHC 385 |
Short or opaque reasons make it difficult for courts to assess whether a decision was unreasonable; reasons must be sufficiently clear and cogent. |
The Court relied on TAR to criticise the brevity and lack of clarity of the impugned decision and to underline that the Court could not accept material gaps being filled by submissions on judicial review. |
| MNN v. Minister for Justice [2020] IECA 187 |
Courts must confine review to the decision itself and not permit ex post facto rationalisation. |
The Court quoted MNN (Power J) to support the conclusion that post-decision explanations could not be used to validate the impugned decision. |
| Mallak v. Minister for Justice [2012] IESC 59; [2012] 3 IR 297 |
The rule of law requires decision-makers to give reasons; without reasons an applicant cannot identify grounds for challenge and courts cannot effectively review decisions. |
The Court used Mallak to frame the obligation to give adequate reasons and to assess whether the impugned decision's reasons were adequate. |
| S v. Minister for Justice [2022] IEHC 578 |
Brevity in decisions is acceptable only if the recipient can understand the decision and how to challenge it; failure to check available contact details may be unreasonable. |
The Court relied on S (Bolger J) to support the proposition that the decision-maker should have taken available steps (e.g. telephoning/contacting references) to verify employer references and that dismissing references without checking can be unreasonable. |
| Mulholland v. An Bord Pleanála (No.2) [2006] 1 IR 453 |
Courts should be circumspect about allowing material gaps in decision reasons to be filled by later submissions on judicial review. |
Referenced by the Court to emphasise that the impugned decision needed to contain sufficient detail to inform a challenge and any re-application. |
| Connelly v. An Bord Pleanála & ors [2018] IESC 31; [2021] 2 IR 752 |
Two related requirements: affected persons must know generally why a decision was made, and they must have sufficient information to consider an appeal or judicial review; reasons must enable a court to engage properly. |
The Court applied Connelly's framework to assess adequacy of reasons and concluded the impugned decision did not meet those requirements. |
| GK v. Minister for Justice [2002] 2 IR 418 |
A decision-maker's statement that all material was considered is generally sufficient unless there is some evidence to the contrary. |
The Court acknowledged GK but concluded that, on the material, the decision-maker's general statement was undermined by evidence of a rigid policy application that suggested the Applicant's particular circumstances had not been properly considered. |
| Rana & anor v. Minister for Justice [2024] IESC 46 |
Reaffirming GK: a claim that a decision-maker ignored material requires evidential support; a general statement of consideration is usually sufficient absent evidence otherwise. |
The Court used Rana to explain the presumption that material is considered but found facts in the present case that negatived that presumption (policy applied inflexibly despite representations). |
| Vishteh v. Minister for Justice [2019] IEHC 131 |
It is arbitrary to insist upon documentation that is impossible for an applicant to provide through no fault of their own. |
The Court relied on Vishteh to hold it was arbitrary/irrational to penalise the Applicant for not producing employment contracts or revenue records that he had explained were not available. |
| Mishra v. Minister for Justice [1996] 1 IR 189 |
Decision-makers must take care that application of policy does not disable or improperly fetter the exercise of discretion in individual cases. |
The Court applied Mishra's principle to find that slavish adherence to policy in the present case effectively fettered the Respondent's discretion. |
| GW v. Commissioner of An Garda Síochána [2025] IEHC 336 |
Policies are permissible guidance but must not operate to bind or disable the decision-maker from exercising discretion in individual cases. |
The Court used GW to reiterate that general policy must be applied with room for individual assessment; it concluded the Respondent had not done so here. |
| Crawford v. Centime [2005] IEHC 328; [2006] 2 IR 106 |
There is a problem where administrative guidelines are elevated and applied as if they had statutory force. |
The Court cited Crawford to criticise the decision-maker for applying departmental policy as though it were conclusive and binding rather than as guidance. |
| Eco Advocacy CLG v. An Bord Pleanála [2025] IEHC 15 |
The weight to be attributed to evidence is generally a matter for the decision-maker rather than the court. |
The Respondent relied on this principle; the Court accepted the general proposition but concluded that the decision-maker's failure properly to engage with key documents deprived that exercise of legitimate weight. |
| DK v. The International Protection Appeals Tribunal [2020] IEHC 14 |
Irrationality is a high threshold; courts should be cautious when reviewing expert or evaluative assessments. |
The Respondent advanced this point; the Court acknowledged the high threshold but found the impugned decision was nonetheless fundamentally at variance with reason and common sense on the facts. |
| AA & ors v. Minister for Justice [2024] IECA 57 |
A decision will be set aside if it is fundamentally at variance with reason and common sense; significant deference is owed to decision-makers but reasons must be discernible. |
The Court applied the AA principles to measure the impugned decision against rationality and the required standard of reasons, concluding the decision failed that test. |
| LTE & anor v. Minister for Justice [2022] IEHC 504 |
Applicants bear the onus of demonstrating a decision is fundamentally at variance with reason and common sense. |
The Court acknowledged LTE in assessing whether the Applicant had met the requisite onus and concluded that he had. |
| Meadows v. Minister for Justice [2010] 2 IR 701 |
In rationality review the court examines whether the decision flows from its premises; the court may use proportionality principles. |
The Court applied Meadows' framework in concluding the impugned decision did not properly flow from its premises and was at variance with reason and common sense. |
| Olatunji v. RAT [2006] IEHC 113 |
If a matter is likely to be important to the determination then it must be fairly put to the applicant to allow an opportunity to answer. |
The Court applied Olatunji to find that the credibility concern about the Irish job offer was a matter that should have been put to the Applicant so he could respond. |
| Idiakheua v. Minister for Justice [2005] IEHC 150 |
Authority on fair procedures and requirement to put significant matters to applicants for comment. |
Quoted through Olatunji and relied upon to support the duty to notify the Applicant of material concerns affecting the decision. |
| BW v. RAT [2017] IECA 296; [2018] 2 ILRM 56 |
Where an issue is material and capable of affecting the outcome an appellant is entitled to a fair opportunity to address it. |
The Court invoked BW to hold that the appeal-stage decision-maker should have afforded the Applicant an opportunity to address the credibility concern where that opportunity had not previously been given. |
| NI (a minor) v. Minister for Justice [2023] IEHC 339 |
It is a breach of fair procedures to hold against an applicant on an argument that was never put to them for comment. |
The Court cited NI to support the view that a material credibility concern should have been raised with the Applicant before the appeal was decided. |
| QUA & anor v. Minister for Justice [2023] IEHC 239 |
Not every issue needs to be expressly raised; only errors sufficiently serious to affect jurisdiction or outcome will justify intervention. |
The Court used QUA to balance whether the failure to put the credibility concern to the Applicant was sufficiently serious to require intervention; it concluded it was. |
| Reid v. An Bord Pleanála [2021] IEHC 230 |
New material that was not before a decision-maker can be admitted only in limited circumstances. |
The Court considered Reid when addressing whether the affidavit from the prospective employer was "new" material; it concluded much of the information in that affidavit had in fact been before the decision-maker. |
| Mukovska v. Minister for Justice [2021] IECA 340 |
A decision based upon a defective chain of reasoning is vulnerable to review; decisions that rely on such reasoning are condemnable. |
The Court cited Mukovska to characterise the OC reasoning as part of a defective chain of reasoning in this case. |
| Balz & anor v. An Bord Pleanála [2019] IESC 90; [2023] 3 IR 751 |
General assertions that "all material was considered" may amount to administrative "throat-clearing" if the decision-maker has not genuinely engaged with material. |
The Court adopted Balz to conclude that the impugned decision's statements that "all evidence submitted has been taken into consideration" were, on the evidence, meaningless administrative boilerplate. |
| BAC v. IPAT [2024] IEHC 297 |
Illustrates the concept of administrative phrases that do not demonstrate real engagement with material. |
Referred to support the point that a blanket statement of consideration does not discharge the duty to engage with an applicant's specific circumstances. |
| Olakunori (a Minor) & ors v. Minister for Justice [2016] IEHC 473 |
Visas arise from executive power rather than statutory authority; policies do not have the force of law. |
The Court used Olakunori to emphasise that departmental policy cannot be treated as if it were statutory and binding. |
| MBB & ors v. Minister for Justice [2022] IEHC 279 |
Serious lack of candour in affidavits can justify refusal of discretionary relief on judicial review. |
The Court considered MBB as a comparator when evaluating whether the Applicant's documentary inconsistencies should lead to refusal of relief; it concluded they did not in this case. |
| Kant & anor v. Minister for Justice [2019] IEHC 583; [2023] 1 IR 765 |
Misconduct and lack of candour may disqualify applicants from discretionary relief. |
The Court referenced Kant in assessing the gravity of the Applicant's inconsistencies and as part of its discretion analysis; it declined to refuse relief on that basis here. |
| State (Furey) v. Minister for Defence [1988] ILRM 89 |
Illustrates availability of cross-examination and procedural tools (RSC O.40, r.36) where affidavit evidence is contested. |
The Court noted State (Furey) in the context of the Respondent's ability to seek cross-examination if the Applicant's averments were deemed unreliable (the Respondent did not do so). |
| Smith & ors v. Minister for Justice [2013] IESC 4 |
Court may refuse to remit a matter if remittal would make no practical difference to the outcome. |
The Court considered Smith when weighing whether remittal would be futile, but concluded remittal was appropriate because the impugned decision was tainted by the identified errors. |
| PNS & anor v. Minister for Justice [2020] IESC 11; [2024] 1 IR 566 |
Judicial discretion to withhold remedies for abusive or egregious conduct should be exercised carefully; courts should be cautious about denying review where underlying rights exist. |
The Applicant relied on PNS to argue the Court should not refuse relief; the Court noted PNS principles but distinguished that PNS turned on EU-derived rights and other features not present here. |
| BD & ors v. IPAT [2025] IESC 38 |
Severance and partial remittal of an administrative decision depend on whether invalid parts can be re-analysed without taking into account the elements in the part found valid. |
The Court applied BD to conclude that the errors in the impugned decision were central and pervasive so that the decision could not stand on other, untainted grounds and remittal was appropriate. |
| The State (Keegan) v. Stardust Compensation Tribunal [1986] I.R. 642 |
Referenced as the "Keegan test" – a foundational formulation for assessing whether a decision is unreasonable. |
Cited indirectly (through Meadows) as part of the rationality framework the Court used when considering whether the decision flowed logically from its premises. |
