Factual and Procedural Background
The Plaintiff and the Defendant entered into a construction contract on 14 August 2017 for a new Children's Hospital in The City. The contract divided works into Phase A (civil/underground) and Phase B (superstructure). Clause 13.2 provided for conciliation of disputed payment claims and, where the Defendant rejected a conciliator's recommendation, required payment subject to a bond and initiation of High Court proceedings.
On 8 January 2019 an instruction to commence Phase B works ("the phase B instruction") was issued by Attorney White of Company A, which the Defendant contends was valid. The Defendant initiated separate proceedings (the "phase B proceedings") on 1 April 2020 seeking declarations as to the validity of that instruction. The High Court (McDonald J) directed, by consent on 4 December 2020, that Module 1 of the phase B proceedings address specified matters including whether contractual mechanisms applied to claimed design changes as at 8 January 2019.
Following conciliator recommendations and payment on provision of bonds, the Plaintiff issued four separate High Court disputes (the frame claim, the global delay claim, the inflation claim and the level 07 steelworks claim). The Plaintiff seeks a stay of those four sets of proceedings pending determination of Module 1 of the phase B proceedings. The application was heard on 24 February 2026 and decided by Judge Sanfey on 3 July 2026.
Legal Issues Presented
- Whether the court should, in the exercise of its inherent jurisdiction and under O.63A, r.5, stay the four High Court disputes pending determination of Module 1 of the phase B proceedings.
- Whether it is appropriate and proportionate to permit the Plaintiff (the initiator of the High Court disputes) to stay proceedings it commenced where the outcome of separate proceedings will determine the proper basis and valuation of those disputes.
- How the principles identified in relevant authorities (including Kalix and Avoncore) apply to the facts, specifically as to necessity, proportionality and avoidance of wasted cost.
Arguments of the Parties
Plaintiff's Arguments
- The resolution of Module 1 is dispositive of the proper basis on which the four disputes should be pleaded and quantified; alternatives cannot realistically be pleaded now.
- Pleading all possible alternative cases would be oppressive, costly (including expert work) and a potentially huge waste of money and resources, diverting key personnel from completing the project.
- No prejudice to the Defendant arises from a stay; pleadings would in any event require revision after Module 1 is decided.
- The phase B module was agreed in December 2020 to resolve the core question first; it should be expedited so that alternative pleading becomes unnecessary.
Defendant's Arguments
- There is no legal basis for the Plaintiff to be excused from prosecuting its own proceedings; the normal course is to require pleadings and case management.
- The Plaintiff can and should plead alternative grounds in outline; the cost of doing so (allegedly up to €500,000) is not disproportionate relative to the total value of claims.
- Pleadings enable the Defendant to understand and interrogate the asserted claims, assist resolution, and do not necessarily require full trials before Module 1 is decided.
- There is a risk that Module 1's decision will be appealed and that the High Court may direct the related disputes to proceed notwithstanding any appeal.

Application by the Court |
| Kalix Fund Ltd v HSBC Institutional Trust Services (Ireland) Ltd [2010] 2 IR 581 |
Factors to consider when staying proceedings pending outcome of other proceedings (necessity, proportionality, extent to which first case will bind others, avoiding unnecessary expense and court time). |
The court applied the Kalix factors in assessing whether a stay was necessary and proportionate, giving weight to the extent Module 1 would determine how the High Court disputes should be run and to avoiding wasted expert and party resources. |
| Avoncore Ltd v Leeson Motors Limited [2021] IEHC 163 |
Confirms the court's broad case management powers (O.63A, r.5) and inherent power to stay related proceedings to avoid duplication and waste; emphasises justice, expedition and cost minimisation. |
The court relied on Avoncore to confirm its jurisdiction to give the procedural direction sought and to frame the stay as a measure no more than necessary and proportionate to prevent unnecessary expense. |
| J & E Davy T/A as Davy v Financial Services Ombudsman & Enfield Credit Union [2008] IEHC 64 |
Permits sequencing of proceedings where one remedy would render another moot to avoid unnecessary cost and public time. |
The court cited this as authority that sequencing (deciding one set of proceedings first when it will render others moot or clarify them) can be justified to avoid otiose expense. |
| Tweed v Amazon.com Inc [2025] IECA 279 |
Addresses consequences of refusing a stay (need to deliver defence, incur discovery and other costs) and the potential for compensation by costs; notes possibility of concurrent trials. |
The court referenced Tweed to acknowledge that refusal of a stay imposes immediate expense but that costs can be addressed; it distinguished the present facts where Module 1 was already agreed to determine core issues. |
| Kirwan v Connors [2025] IESC 21 |
General principles on delay and the court's approach to applications to dismiss for want of prosecution; caution against sanctioning inappropriate delay. |
The court considered Kirwan in assessing the reasonableness of delay in advancing the phase B module and in ensuring that any stay does not countenance inappropriate delay; it noted the parties had previously agreed the module and that the stay would be case-managed to ensure expedition. |
Court's Reasoning and Analysis
The court began from O.63A, r.5 and the court's inherent jurisdiction to give procedural directions, including stays, aimed at a just, expeditious and cost-minimising resolution. Applying the Kalix and Avoncore principles, the court assessed necessity and proportionality: whether Module 1 would substantially determine how the High Court disputes should be pleaded, valued and case-managed, and whether requiring alternative pleading now would cause disproportionate and unnecessary expense.
The court found that the parties had already agreed in December 2020 that Module 1 should address the validity and consequences of the phase B instruction and that the determination of that module would materially affect formulation and quantum of the four disputes. The Plaintiff demonstrated that pleading all permutations would require substantial expert work, divert key personnel and likely generate large wasted costs. The Defendant accepted that at least two disputes could not proceed without Module 1 and relied primarily on proportionality of cost given the high value of claims.
Balancing these considerations, the court concluded that a stay would prevent unnecessary duplication, promote clarity, and could be managed to ensure expedition; any stay must be no more than necessary and proportionate. The court also addressed delay concerns, noting the parties' prior consent to the module and that the module could be expedited under commercial case management powers.
Holding and Implications
STAY GRANTED
Holding: The court ordered that no further steps be taken in the four High Court disputes (the frame claim, the global delay claim, the inflation claim and the level 07 steelworks claim) pending determination of Module 1 of the phase B proceedings, or until further order of the court. The matter was listed for directions on 22 July 2026 to consider terms of the order and ancillary matters including costs.
Implications: The direct effect is that the Plaintiff's four proceedings are stayed pending determination of the agreed phase B module; parties are to case-manage Module 1 on an expedited basis. The decision was framed as a procedural management direction under existing principles and did not purport to establish new legal precedent beyond its application of established authorities.
