Hallahan v Cork City Council (Approved)

Factual and Procedural Background

Plaintiff, employed by Defendant since 2010, became Head of Finance in 2016 and led a 68-person Finance Department. His functions included budget preparation, financial planning, financial-resource management, capital-project appraisal, accounting compliance and financial governance. [1][2][3][4]

In May 2026, Defendant proposed transferring Plaintiff to a newly created Head of Cost Transformation role and appointing Employee A as Head of Finance. Plaintiff objected, invoked the workplace Grievance Procedure and maintained that his existing position should continue. [5][6][7][8][9][10]

Proceedings issued on 19 May 2026. Interim orders restrained Defendant from treating Plaintiff as other than Head of Finance or assigning his duties to another person; those orders were continued by consent. [11][12][13][14][15]

Defendant later rescinded Plaintiff’s proposed appointment, appointed Employee A to the cost-transformation role and sought to transfer certain of Plaintiff’s functions to Employee A. The application ultimately concerned whether that reassignment should be permitted pending trial. [16][17][18][19][20]

Legal Issues Presented

1. Whether Plaintiff raised a fair question to be tried concerning Defendant’s exercise of contractual discretion under the Braganza principle. [21][22][23]
2. Whether Defendant breached the Grievance Procedure by refusing to recognise Plaintiff’s solicitor’s letter as invoking that procedure and its status-quo protection. [24][25][26]
3. Whether the balance of convenience favoured restraining the reassignment of Plaintiff’s duties pending trial. [27][28]
4. Whether Delegation Order 2417/26, including the proposed duplication of functions, breached the existing High Court order. [20][29][30][31]

Arguments of the Parties

Plaintiff’s Arguments

• Defendant initially attempted to remove Plaintiff from Head of Finance without adequate notice or consultation and later sought to transfer important functions to Employee A in a manner that diminished and humiliated him. [21][32]
• The contractual power to alter the Department or Directorate to which Plaintiff was assigned did not authorise the proposed changes, and Defendant failed to comply with the implied constraints on contractual discretion. [33][22]
• Defendant breached the Grievance Procedure, which required the status quo to be maintained during the grievance process. [24][26]
• The proposed reassigned functions represented approximately 40% of Plaintiff’s working time, and immediate implementation would cause professional and reputational harm that damages could not adequately remedy. [34][27][35]

Defendant’s Arguments

• The contractual provision reserving the right to alter Plaintiff’s Department or Directorate authorised the reassignment. [33][36][37]
• The proposed cost-transformation arrangements were materially different from the significant change considered in Earley and would leave Plaintiff with meaningful duties. [38]
• Defendant needed to restructure urgently because of a serious and worsening financial position, and the reassignment was necessary to address that crisis. [39][40][41][19]
• Defendant disputed that Plaintiff’s correspondence validly invoked the Grievance Procedure and maintained that the procedure did not permit solicitors to invoke it on his behalf. [36][10][42]

Court’s Reasoning and Analysis

The Court held that the ordinary “fair question” threshold applied because Plaintiff sought preservation of the existing position rather than an order requiring Defendant to take positive action. [58][59]

The contractual right to alter Plaintiff’s Department or Directorate did not conclusively authorise the proposed reassignment. The Court accepted that the roles were related and that the case differed from Earley, but found that removing Plaintiff from a large, established and influential department and placing him in a newly created role of uncertain scope was a major employment change. [60][43]

The Court considered Defendant’s reliance on an asserted managerial practice insufficient at this stage. The circumstances of other reassignments were not established, and a practice introduced years after Plaintiff’s contract could not, merely through subsequent existence, determine the contract’s original meaning. [61][62][63]

Under the Braganza principle, Defendant’s discretion had to be exercised honestly, genuinely, in good faith and without arbitrariness, capriciousness, perversity or irrationality. The absence of prior consultation, the uncertain structure and resources of the new role, the later criticism of Plaintiff and the transfer of functions previously held by him created a fair question as to compliance with that implied term. [64][65][55][61][32][25]

The Court also found a fair question concerning the Grievance Procedure. Nothing in the procedure prevented communication through a solicitor, and a letter expressly stating that the procedure was being invoked could not necessarily be treated as a nullity. Because the grievance concerned the CEO’s own conduct, an independent recipient might have been necessary to make the process effective. [26][66][67]

On the balance of convenience, the Court found that implementing the changes immediately could cause humiliation, reputational damage and practical difficulties that could not adequately be remedied by damages if Plaintiff later succeeded. [27][35]

Although Defendant’s financial difficulties were a significant consideration, the evidence did not establish that the immediate transfer of the disputed functions was sufficiently urgent or necessary. The Court noted the delay before the new role was proposed, the absence of consultation, the disputed financial evidence, the continued involvement of Plaintiff in budget preparation and the unexplained addition of budget-related functions when Employee A was appointed. [68][69][70][71][72][28]

Holding and Implications

INJUNCTION GRANTED: The Court ordered Defendant, pending trial or further order, not to assign Plaintiff’s duties to another person. Reassignment remained possible with Plaintiff’s prior agreement. [73][30]

The proposed duplication of functions between Plaintiff and Employee A would breach the order, even if senior officers were used to arbitrate between competing recommendations. The proceedings were directed to progress expeditiously, and Plaintiff was required to deliver a Statement of Claim. [74][75][76][77]

The decision preserves the existing allocation of functions pending trial; it does not determine the ultimate contractual merits or prevent Defendant from pursuing compliant organisational changes in the future. [35][75][78]
