Summary of Judgment — The High Court (Record No. HP 2026/1248) — Judgment delivered 8 May 2026

Factual and Procedural Background

The Plaintiff commenced these proceedings by Plenary Summons on 9 March 2026 against Company A. The Plaintiff alleges serious mistreatment by Company A during her employment; Company A emphatically denies those allegations. The Plenary Summons pleads a range of remedies including interlocutory injunctions (restraining Company A from treating the Plaintiff's contract as terminated and directing immediate reinstatement of pay), damages for breach of contract and wrongful dismissal (constructive dismissal), declarations of constructive dismissal, loss of earnings and other reliefs.

The Plaintiff swore a grounding affidavit on 9 March 2026 (and a supplemental affidavit on 23 March 2026) asserting that Company A's conduct deprived the contract of its substance and that she resigned on 23 January 2026 (elsewhere variously averred as 25 November 2025, 12 January 2026 or 23 January 2026). Company A, by way of a replying affidavit sworn by Attorney Casey on 18 March 2026, provides a detailed factual chronology disputing the Plaintiff's account and asserting that the Plaintiff resigned (accepted by Company A on 10 February 2026) and, prior to resignation, had numerous performance, conduct and procedural issues addressed by Company A.

The Plaintiff had also pursued multiple alternative statutory and administrative remedies: applications and interlocutory hearings before the City Circuit Court pursuant to the Protected Disclosures Act 2014, 17 claims before the Workplace Relations Commission (WRC) across multiple complaint forms and other statutory complaints. Company A contends the substantive issues fall within those statutory forums.

The High Court (Judge Jordan) heard argument and evidence on the Plaintiff's interlocutory application for mandatory relief and for restoration of pay pending trial.

Legal Issues Presented

1. Whether the Plaintiff has established a "strong case" (i.e. a case which will probably succeed at trial) sufficient to justify the grant of the mandatory interlocutory injunctions sought (restraint on treating the contract as terminated and immediate reinstatement of salary and entitlements).
2. Whether the Plaintiff's pleaded case should properly be litigated in the High Court or in statutory/administrative fora (WRC, Circuit Court under the Protected Disclosures Act 2014, and unfair dismissal procedures under the 1977 Act), and whether statutory remedies preclude parallel common law relief.
3. Whether, having regard to the balance of convenience, adequacy of damages and the risk of micro-managing employment, interlocutory relief restoring pay and enforcing continued employment should be granted.
4. Whether the Plaintiff's conduct of litigation (multiple overlapping proceedings and alleged failure of candour about resignation) amounts to an abuse of process affecting entitlement to equitable relief.

Arguments of the Parties

Plaintiff's Arguments

• The Plaintiff seeks interlocutory mandatory relief: an order restraining Company A from treating her contract as terminated and orders restoring her monthly salary and contractual entitlements withheld since 25 February 2026.
• The Plaintiff contends she was constructively dismissed by reason of Company A's conduct and seeks to maintain claims for breach of contract, wrongful dismissal, penalisation (protected disclosure) and related losses.
• The Plaintiff asserted in written submissions (contrary to her affidavits) that she did not resign and that the contract remains subsisting (relying on contractual notice provisions).

Company A's Arguments (as advanced by Attorney Casey)

• Company A disputes the Plaintiff's allegations and advances a comprehensive chronology showing performance and conduct concerns, disciplinary processes, occupational health involvement and attempts to resolve grievances.
• Company A asserts the Plaintiff resigned (variously pleaded) and that resignation was accepted on 10 February 2026; accordingly, the Plaintiff is not entitled to reinstatement of salary post-resignation.
• Company A submits that where statutory remedies exist (WRC, unfair dismissal procedures, Protected Disclosures Act remedies) the High Court should not exercise a parallel common law jurisdiction to grant the relief sought.
• Company A argues the Plaintiff has not established a strong case and that the balance of convenience and adequacy of damages favour refusal (including concerns about micro-managing the employment relationship and the Plaintiff's refusal to engage with internal processes).
• Company A contends the Plaintiff's multiple proceedings and inconsistent sworn evidence amount to an abuse of process undermining entitlement to equitable relief.

Court's Reasoning and Analysis

The Court accepted Attorney Casey's affidavit and accompanying exhibits as cogent and accurate. The Court identified a central evidential contradiction: the Plaintiff's sworn affidavits repeatedly and unambiguously averred she had resigned (giving specific dates), yet her written submissions before the High Court advanced that she had not resigned. The Court held the Plaintiff is bound by her sworn evidence and found the written submissions inconsistent with that evidence.

The Court applied the established legal framework for mandatory interlocutory injunctions (Merck; Maha Lingam; Mason; Earley), requiring a strong case likely to succeed at trial. On the evidence presented, the Court concluded the Plaintiff had not established such a strong case: Company A's detailed factual narrative (supported by documents) was not credibly or persuasively refuted by the Plaintiff.

The Court examined jurisdictional and alternative remedy issues. It concluded that many of the Plaintiff's substantive complaints (constructive dismissal, penalisation, unfair dismissal, wage claims) fell within statutory schemes and administrative fora (WRC, Protected Disclosures Act procedures, unfair dismissal regime under the 1977 Act). Citing authorities (Orr; Nolan; Kearney; McGrath; Power), the Court held that where a statutory remedial scheme exists, the High Court should not grant parallel common law interlocutory relief.

On balance of convenience and adequacy of damages, the Court considered authorities cautioning against micro-managing employment and restoring pay where the employment relationship had irretrievably broken down (Nolan v. Science Foundation Ireland; Moylist; Buttimer). The Court noted the practical problem of ordering Company A to pay the salary of a person who had resigned or who refused to carry out duties, and the Plaintiff's failure to provide evidence of means to satisfy undertakings as to damages. The Court also observed the multiplicity of proceedings (WRC, Circuit Court, statutory complaints) and the risk of abuse of process arising from inconsistent sworn evidence and repeated litigation.

Holding and Implications

DISMISSED.

Holding: The Plaintiff's interlocutory application for mandatory injunctions (including restraint on treating the contract as terminated and restoration of salary/entitlements) is dismissed. The Court found the Plaintiff failed to establish a strong case to be tried, that statutory remedies and fora are the appropriate channels for many of the Plaintiff's complaints, and that the balance of convenience and other equitable considerations weigh heavily against granting the relief sought.

Implications: The direct consequence is that no interlocutory relief is granted in these High Court proceedings; the Plaintiff's substantive claims remain for determination in the appropriate statutory fora (WRC, Circuit Court under the Protected Disclosures Act, unfair dismissal procedures) as applicable. The Court noted the dismissal does not create new precedent beyond application of established principles; it emphasised the risk of abuse of process arising from overlapping litigation and inconsistent sworn statements and listed the case to deal with costs and any consequential matters. No interlocutory restoration of pay or order restraining Company A from treating the employment as terminated was made.
