Commercial litigation in Ireland — an overview

Most commercial disputes do not go to trial. The discipline of preparing for trial is what produces the settlement, and the discipline of preparing well is what produces a settlement on favourable terms. This is a working note on the structure of commercial dispute resolution in Ireland — the courts, the procedure, the timetable, the costs — written for the CFO or business owner who is at the start of a dispute and wants to understand the terrain before commissioning the substantive advice.

The structure of the courts

Irish commercial litigation is conducted in the High Court. The High Court is divided into specialist lists, and a Commercial Court list (technically the Commercial List of the High Court) operates as a case-managed list for substantial commercial disputes. Entry to the Commercial List requires application, with a value threshold (currently €1 million for most disputes) and a discretionary element. The Commercial List is the appropriate forum for most significant commercial litigation in Ireland.

Below the High Court sit the Circuit Court (for claims up to €75,000) and the District Court (for claims up to €15,000), which handle the great volume of smaller commercial disputes. Above the High Court sit the Court of Appeal and the Supreme Court. The Supreme Court hears appeals on points of general public importance or in the interests of justice; the Court of Appeal hears the routine appeals from the High Court.

The Commercial List's procedure is faster than the general High Court. Cases are case-managed by a judge from the outset, with strict timetables for pleadings, discovery, witness statements and trial. The Commercial List produces judgments in months where the general list produces judgments in years. The List is, in my experience, the most efficient civil court in Ireland for substantial commercial disputes.

The pre-litigation period

The pre-litigation period is where the strategic decisions are made. The party with the dispute must decide whether to litigate, to mediate, to arbitrate, or to settle. The choice depends on the value of the claim, the strength of the evidence, the relationship between the parties, the cost of each option, and the speed at which a resolution is needed.

For most commercial disputes worth more than a few hundred thousand euro, formal pre-action correspondence is the first step. A letter from solicitor to solicitor setting out the claim, the legal basis, the loss claimed and the relief sought. The recipient's solicitor responds, usually within a few weeks, with a denial, an acceptance, or a counter-proposal. The exchange can run to several rounds before either litigation or settlement.

The Court Rules require that the parties consider mediation before issuing proceedings, and most Commercial List matters have a mediation directed at some point during the litigation. Mediation is not a substitute for legal preparation; it is most effective when both parties have a clear view of their position, which usually means after some discovery.

Pleadings and the case-management timetable

Litigation begins with the issue of proceedings — a plenary summons in the High Court for a general commercial dispute, with subsequent statement of claim and defence. The Commercial List has its own case-management procedure under Order 63A of the Rules of the Superior Courts. The plaintiff files a statement of claim within a few weeks of entry to the List; the defendant files a defence within a few weeks of the statement of claim; replies and other interlocutory pleadings follow on a case-managed timetable.

The Commercial List's typical timetable from entry to trial is twelve to eighteen months. The general High Court list runs at twenty-four to thirty-six months. The pace of the Commercial List is the principal reason most substantial commercial disputes seek entry.

Discovery

Discovery is the disclosure of documents relevant to the issues in the proceedings. The Irish discovery rules require each party to disclose documents within its possession, power or procurement that are relevant to a matter in issue and necessary for fairly disposing of the case. The "necessary" requirement is the discipline that prevents discovery from becoming a fishing expedition.

Discovery is typically the longest and most expensive part of commercial litigation in Ireland. The volume of documents in a corporate dispute can run to hundreds of thousands of emails and contracts; the cost of reviewing them is substantial; the time required is months. The Commercial List manages discovery actively, with the judge often imposing tight limits on the categories of documents required and the deadlines for their production.

For an Irish business preparing for litigation, the practical discipline is to identify and preserve relevant documents at the earliest sign of a dispute. A litigation hold notice should be issued to all relevant personnel, IT should suspend any automatic deletion policies, and a contemporaneous record of the preservation steps should be maintained. The cost of preservation is small; the cost of failing to preserve, when the documents are needed, can be a finding of breach and an inference against the party.

Trial and judgment

Commercial Court trials are conducted before a single judge without a jury. The standard procedure involves opening submissions, witness evidence in chief, cross-examination, re-examination, closing submissions, and a reserved judgment. Trials in the Commercial List typically last from two days for a discrete issue to two months for a major corporate dispute. Judgment is reserved and delivered usually within three to six months of the trial.

The Commercial Court judgment is binding on the parties and, subject to appeal, conclusive. Enforcement of an Irish High Court judgment within Ireland proceeds under the Court's own enforcement procedures — execution against assets, garnishee orders, examination of judgment debtor, and so on. Cross-border enforcement against assets outside Ireland proceeds under the applicable recognition regime; for EU member states this is now the Brussels I Recast Regulation, with the UK now outside the regime as discussed in Brexit and your commercial contracts.

Costs

The general rule on costs in Irish litigation is that the loser pays the winner's costs. The rule is not absolute — the court has discretion to award costs differently where the conduct of a party or the merits of the case justify it — but as a starting position, a defendant who loses pays the plaintiff's reasonable legal costs, and vice versa.

The Irish costs regime is more aggressive than the English regime in some respects and less in others. Successful parties in Ireland routinely recover the great majority of their costs, but the assessment process — adjudication by the Legal Costs Adjudicator — can take many months and produces a figure that is typically lower than the actual costs incurred. The economic position is that even a successful party pays a portion of its own costs.

For a CFO budgeting for litigation, the working figure is that fees on a Commercial List matter from entry to judgment run from several hundred thousand euro for a discrete dispute to several million for a major corporate matter, with the great variation being the volume of discovery and the length of trial. The economics rarely favour litigation as a financial strategy on its own; the case for litigating is almost always non-financial — protection of a contractual position, preservation of a market reputation, defence of a regulatory finding, vindication of a property right.

Alternatives — arbitration and mediation

Arbitration is the principal alternative to litigation for substantial commercial disputes in Ireland. The Arbitration Act 2010 implements the UNCITRAL Model Law and provides a modern framework for both Irish-seated and international arbitration. Arbitration is private, the procedure is more flexible, the timetable can be faster, and the resulting award is enforceable internationally under the New York Convention 1958. The costs are sometimes higher than litigation, sometimes lower, depending on the institution and the complexity.

Mediation is the principal alternative to adversarial dispute resolution. The Mediation Act 2017 provides a statutory framework for mediation in Ireland, with confidentiality protections, enforceability of mediated agreements and a duty on solicitors to advise clients on the option. Most commercial mediations in Ireland are conducted by accredited mediators on a confidential basis, with a typical mediation lasting a single day and producing either a settlement or a clearer view of the next step.
