New Procedural Dawn: An Analysis of the 2024-2025 Reforms to Interrogatories in Irish Civil Litigation

Part I: The Old Regime: Interrogatories as a Reluctant Tool

To fully appreciate the significance of the 2024-2025 reforms, it is essential to first understand the procedural landscape that preceded them. Historically, interrogatories—a series of written questions posed by one party to another, to be answered on oath—were a relatively uncommon feature of Irish civil litigation outside of a few specific contexts. While the Rules of the Superior Courts provided for their use, the framework was such that they were often perceived as a secondary, and frequently cumbersome, procedural tool rather than a primary instrument for advancing a case. This underutilisation was not due to a lack of potential utility but was a direct consequence of the procedural hurdles embedded within the old rules, which created a climate of practitioner reluctance.

The General Rule: Leave of the Court Required

The central feature of the pre-reform regime under the former Order 31, Rule 1 of the Rules of the Superior Courts (RSC) was the requirement for a litigant to obtain prior leave of the court before delivering interrogatories.¹ This was not a mere formality; it necessitated a formal application by way of motion, grounded on an affidavit, which had to be served on the opposing party.¹ This initial step immediately introduced an element of cost, delay, and uncertainty into the process. Legal practitioners had to weigh the expense of preparing and arguing the application against the possibility that the court might refuse leave, making it a difficult course of action to recommend to clients in all but the most clear-cut circumstances.

The court’s decision to grant or refuse leave was governed by a specific and demanding threshold. Under the old rules, leave would only be granted for such interrogatories as the court considered “necessary either for disposing fairly of the cause or matter or for saving costs”.¹ This “necessity” test formed the core of the court’s gatekeeping function. In making its determination, the court was also required to take into account any offer made by the party sought to be interrogated to provide the information through alternative means, such as delivering further particulars, making admissions, or producing documents.¹ This created a dynamic where a party could potentially fend off an application for interrogatories by offering a lesser form of disclosure, further complicating the strategic calculations for the party seeking information.

The practical effect of this framework was to create a significant procedural barrier. The combination of upfront costs, the uncertainty of success, and the demanding “necessity” test fostered a cautious approach among practitioners. This caution, in turn, led to a self-fulfilling prophecy: because interrogatories were used infrequently, a deep and practical body of modern jurisprudence on their application outside of specialist areas failed to develop. This lack of familiarity further discouraged their use, cementing the perception of interrogatories as a “forgotten weapon” ⁵ and solidifying the far more costly and burdensome discovery process as the default, and often only, pre-trial information-gathering procedure.

Limited Exceptions to the Leave Requirement

The general rule requiring leave of the court was subject to two main exceptions. The first, and most historic, was for cases where relief was sought on the grounds of “fraud” or “breach of trust”.¹ In such actions, both plaintiffs (after delivering the statement of claim) and defendants (at or after delivering the defence) could serve one set of interrogatories without a court order. This exception has its roots in the origins of the procedure in the old Court of Chancery, which had an equitable jurisdiction to uncover wrongdoing.⁷

A more modern exception existed for proceedings admitted to the Commercial List of the High Court. The rules governing the Commercial Court, designed to facilitate proactive and efficient case management, permitted parties to deliver interrogatories without leave.² This reflected a judicial recognition that in complex commercial disputes, the ability to narrow issues through targeted questions was a vital component of effective litigation. However, the existence of this exception created a procedural anomaly. As O’Moore J. noted in

Kiely v U2 Limited IEHC 153, it was an “illogical vagary” that a case qualifying for the Commercial Court could avail of this efficient tool freely, while a case of similar complexity outside that list faced the significant hurdle of a court application.⁸ This disparity highlighted the inconsistency in the procedural rules and the need for a more uniform approach.

Judicial Perception and Practitioner Reluctance

Despite the restrictive framework, there was periodic judicial encouragement for the greater use of interrogatories. As far back as 1967, the Supreme Court in J & LS Goodbody Ltd v Clyde Shipping Co Ltd stated that interrogatories “ought to be used more than they are” because they serve to narrow issues and reduce the area of proof, resulting in considerable savings of time and money.² More recently, before the reforms, judges in the Commercial Court and the Court of Appeal had also highlighted their benefits.²

However, this judicial encouragement did little to change the prevailing culture among practitioners. There remained a widespread perception that the Irish courts were generally slow to grant leave and that applications were often met with resistance.⁵ This perception, coupled with the procedural complexities, meant that interrogatories remained a niche tool, largely confined to the specific exceptions where leave was not required. The path of least resistance for most practitioners was to proceed directly to the more familiar, albeit more cumbersome, process of discovery.

Under the old rules, a party who had been served with interrogatories (either with or without leave) could object to answering specific questions within the answering affidavit itself on grounds that they were “scandalous or irrelevant, or not bona fide for the purpose of the cause or matter”.² Alternatively, a party could bring a separate application to the court within seven days to have the interrogatories set aside on the grounds that they had been “exhibited unreasonably or vexatiously, or struck out on the ground that they are prolix, oppressive, unnecessary, or scandalous”.¹ This dual system for objections added another layer of potential procedural wrangling to the process.

Part II: The Catalyst for Change: Judicial Frustration and the “Discovery Monster”

The 2024-2025 reforms to interrogatories did not emerge from a procedural vacuum. They were a direct and forceful response to a growing and widely acknowledged “crisis” within the Irish civil justice system: the process of discovery.¹¹ For years, senior members of the judiciary had become increasingly vocal in their criticism of a discovery regime rooted in 19th-century legal principles, which they argued had become utterly unsuited to the realities of 21st-century litigation in the digital age.¹¹ This judicial frustration, coupled with institutional inertia in implementing recommended reforms, created the fertile ground from which the new interrogatories rules grew.

The “Monster” of Discovery

The central problem, as articulated with increasing urgency by the High Court bench, was that the discovery process had mutated into a “monster” that threatened to overwhelm the very system of justice it was designed to serve.¹¹ In an era of mass electronic information, the traditional obligation on parties to identify and produce all “relevant” documents had become a source of immense financial burden, crippling delays, and procedural complexity that often overshadowed the substantive issues in dispute. The judiciary warned that this system was imposing intolerable strains on litigants and, in some cases, actively “obstructing” justice rather than facilitating it.¹¹

Mr. Justice Twomey became a particularly prominent critic of this state of affairs. In his 2025 judgment in Recorded Artists Actors Performers Ltd v. Phonographic Performance (Ireland) Ltd, he provided a stark illustration of the problem. He noted that the defendant in that case was required to search an astonishing 1.78 million electronic documents. The cost of having a single lawyer review the potentially relevant documents was estimated at up to €250,000, meaning the total cost for discovery alone could approach €500,000 for both parties.¹¹ Twomey J. lamented that the court, which is “supposed to administer justice,” had no choice but to apply these antiquated 19th-century rules that were manifestly unfit for purpose.¹¹

This sentiment was echoed by other judges. As early as 2018, Mr. Justice Hogan of the Court of Appeal had described the operation of the discovery regime as a “crisis” and strongly advocated for the use of alternative procedures, such as interrogatories and notices to admit facts, which he argued should be properly explored before any extensive discovery orders were made.¹² The judiciary was clearly signalling that the status quo was unsustainable and that more proportionate, targeted methods of information exchange were urgently needed.

The Unimplemented Kelly Report and the Supreme Court’s Caution

The judicial criticisms were not merely anecdotal; they were supported by the comprehensive findings of the 2020 Report of the Review Group on the Administration of Civil Justice, chaired by former High Court President, the Hon. Mr. Justice Peter Kelly (the “Kelly Report”). The report concluded in stark terms that the existing discovery rules were “completely unsuited” to the digital era and had grown into a “monster” that represented a “real and pressing threat to the administration of justice”.¹¹ The Kelly Report proposed a practical solution: a new draft court order to replace the existing discovery rules entirely.¹¹

However, despite the clarity of its findings and the urgency of its recommendations, the proposed reforms were not implemented by the Oireachtas. As Twomey J. noted with palpable frustration, the draft order from the Kelly Report was left “unimplemented on the shelf” for years.¹¹ This legislative inaction created a significant tension within the judicial system.

Adding to this tension was the more conservative stance adopted by the Supreme Court. In the landmark case of Tobin v Minister for Defence, the Supreme Court, while acknowledging the problems with discovery, reasserted its fundamental importance in the Irish legal system, arguing that its advantages still largely outweighed its disadvantages.¹¹ Crucially, the Court rejected the proposition advanced by the Court of Appeal that a party should be required to exhaust alternative remedies like interrogatories

before seeking discovery. Instead, the Supreme Court held that the onus should fall on the party from whom discovery is sought to demonstrate why a less burdensome alternative would be more appropriate.¹⁴ The Court also expressed scepticism about the universal cost-saving benefits of interrogatories, reasoning that in many instances, the responding party would still have to undertake the same burdensome search of its documents to find the answers to the questions posed.¹⁴

This judgment effectively applied a brake to the procedural revolution being advocated by the High Court. It created a situation where the High Court bench was acutely aware of a crisis, had a blueprint for reform in the Kelly Report, but was constrained by both legislative inaction and a more cautious jurisprudence from the highest court. The introduction of the new interrogatories rules in 2024 can therefore be understood as a pragmatic and targeted initiative by the Superior Court Rules Committee, heavily influenced by the judiciary, to take matters into its own hands. It was a way to enact the spirit of the Kelly Report’s recommendations and empower litigants with the tools the High Court had been calling for, without requiring a full legislative overhaul of discovery. It was a “bottom-up” judicial solution, working around the legislative logjam and the constraints of the Tobin judgment to address the most pressing issue of proportionality in pre-trial procedure.

This drive for reform was also connected to another area of judicial concern: the quality of pleadings. The courts have become increasingly critical of vague or “boilerplate” pleadings, particularly “blanket defences” that fail to properly identify the real issues in dispute.³ Cases like

Morgan v. ESB IECA 29 and Crean v Harty IECA 364 have underscored the statutory requirement for parties to plead with precision and particularity.³ Vague pleadings directly contribute to the discovery “monster” by expanding the universe of potentially “relevant” documents. In this context, interrogatories were seen as a powerful tool to cut through uninformative defences and force parties to commit to a factual position on oath, thereby narrowing the scope of the dispute from the outset.³

Part III: The Core of the Reform: A Detailed Examination of S.I. No. 363 of 2024 (Superior Courts)

The culmination of the judicial push for more proportionate pre-trial procedures arrived in the form of Statutory Instrument (S.I.) No. 363 of 2024, titled the Rules of the Superior Courts (Interrogatories) 2024. These rules, which came into effect on 31 July 2024, represent the most significant reform of this area of civil procedure in decades.⁶ They fundamentally altered the process by replacing rules 1 to 11 of the old Order 31 and establishing a new, streamlined regime.⁶ Significantly, the new rules apply to all proceedings, including those that had been commenced before the implementation date, ensuring their immediate and widespread impact.¹⁷

The “Leave-Free” Quota: A Procedural Revolution

The cornerstone of the reform is the abolition of the need for prior court leave for a limited set of interrogatories. The new Rule 1 allows a party, at any time after delivering their Statement of Claim or Defence, to deliver one set of interrogatories, containing no more than 20 questions, to any other party in the proceedings without an order of the Court.⁶

This single change dismantles the primary procedural and economic barrier that had led to the historic underuse of interrogatories. By creating a “leave-free” quota, the rules transform interrogatories from a high-threshold, exceptional procedure into a standard, accessible tool available to litigants in every High Court action. This move is clearly intended to encourage their use as a first port of call for narrowing issues, potentially even before the more burdensome process of voluntary discovery is initiated.⁶

While the initial set of 20 is now a right, the rules maintain court oversight for more extensive questioning. A party wishing to deliver more than 20 interrogatories, or to deliver a second or subsequent set to the same party, must still apply to the Court for leave to do so.¹⁷ This preserves the court’s role in preventing abuse while liberalising the initial use of the procedure.

The Quid Pro Quo: Strict Drafting Requirements under the New Rule 2

The new freedom to serve interrogatories without leave is balanced by the introduction of strict, codified requirements for how those questions must be drafted. The new Rule 2 acts as the quid pro quo for the removal of the court’s preliminary gatekeeping function, placing the onus squarely on the practitioner to draft compliant and justifiable questions. Failure to adhere to these requirements provides the responding party with clear grounds for objection. The key requirements are:

Statement of Necessity: The interrogatories must be prefaced with a brief statement explaining why answers to each interrogatory or group of interrogatories are “necessary for disposing fairly of the cause or matter or for saving costs”.¹⁷ This incorporates the old necessity test directly into the document itself, requiring the interrogating party to justify their questions from the outset.
Confined to Fact, Not Evidence: This is perhaps the most critical substantive limitation. The new rules codify a long-standing principle from case law, stipulating that questions must be confined to “facts in issue” or “facts reasonably relevant to establish facts in issue,” but explicitly exclude questions concerning the evidence by which any fact might be proved.¹⁷ This distinction is crucial. Interrogatories are for eliciting primary facts, not for cross-examining the other party on paper about their intended evidence, opinions, or legal arguments.⁴ The 2024 High Court decision in
Ryan v Haq & Ors IEHC 215 provides a perfect illustration of this principle in action. In that case, the court refused to permit an interrogatory that effectively asked the defendants to state which of them the plaintiff had a contract with, ruling that this was a question of law and legal interpretation, not a question of fact suitable for an interrogatory.²⁰
Within Knowledge of the Responding Party: The questions must be confined to matters of fact that are “likely to be within the knowledge of the person required to answer,” having made any “reasonably necessary inquiries”.¹⁷ This obliges the responding party to do more than simply rely on the personal knowledge of the individual swearing the affidavit; they must take reasonable steps to ascertain the facts from within their organisation or control.
Amenable to a Short, Factual Answer: The rules require that questions must be capable of being answered by “an affirmative, negative or short statement of fact without narrative”.⁶ This is designed to ensure clarity and prevent the process from becoming a lengthy exchange of written submissions. The questions must be “crystal clear” to elicit a clear answer.¹⁸

New Protocols for Response and Objection

The reforms also modernise the procedures for responding and objecting to interrogatories. The timeline for a response has been extended from the previous 10 days to 21 days, or such other time as the parties may agree or the court may direct.⁶ This provides a more realistic timeframe for the responding party to conduct necessary inquiries and prepare a sworn affidavit. The answering affidavit (new Form No. 9 in Appendix C) must now set out the full text of each interrogatory immediately prior to the corresponding answer, improving the clarity and usability of the document.¹⁷

The procedure for objecting has also been formalised. Instead of simply making an objection within the body of the affidavit, a party must now deliver and file a separate notice of objection. This notice must set out the grounds of objection concisely.⁶ Critically, the notice can also include details of any “alternative means” by which the party is willing to address the matter raised in the question, for example, by providing further particulars, making a formal admission, or producing a specific document.¹⁹ This introduces a new, constructive element to the objection process, encouraging parties to find pragmatic solutions rather than simply refusing to engage.

Enforcement and Sanctions

The new rules establish a clear and time-limited process for enforcement. If the interrogating party is not satisfied with the answers provided or the objections raised, they have 14 days from the delivery of the response to apply to the court by motion to compel answers or further answers.¹⁷

On hearing such an application, the court has a wide range of powers. It can order the interrogated party to answer further, either by affidavit or by viva voce (oral) examination.¹⁹ Alternatively, the court can determine that the party is not required to answer, particularly if the interrogatories do not comply with the strict requirements of Rule 2, or if they are found to be “unreasonably or vexatiously” delivered, or are “prolix, oppressive, unnecessary, or scandalous”.¹⁹

To deter abuse of the new, more liberalised system, the rules include a powerful sanction regarding costs. The new Rule 11 provides that if the court is of the opinion that any interrogatories were delivered unreasonably, the costs occasioned by those interrogatories and the answers thereto may be directed to be paid by the party found to have behaved unreasonably “in any event”—that is, regardless of the ultimate outcome of the entire action.¹⁷ This provides a significant deterrent against using interrogatories for tactical harassment or as a fishing expedition.

The following table provides a summary of the key procedural shifts for practitioners.

Procedural Aspect	Pre-S.I. 363 of 2024 Regime (Former Order 31)	Post-S.I. 363 of 2024 Regime (New Order 31)
Leave Requirement	Leave of the Court required for most cases.¹	No leave required for the first set of up to 20 interrogatories.⁶
Number of Interrogatories	No specified limit, but the number and scope were subject to court approval during the leave application.¹	A party may deliver up to 20 interrogatories without leave. Leave is required for more than 20 or for subsequent sets.¹⁷
Time to Respond	10 days to file an answering affidavit.¹	21 days to deliver an answering affidavit and/or notice of objection.⁶
Basis for Questions	Had to be “necessary either for disposing fairly of the cause or matter or for saving costs”.¹	Must comply with the strict criteria in the new Rule 2, including a statement of necessity and being confined to fact, not evidence.¹⁷
Objection Procedure	Objections could be made in the answering affidavit or via an application to set aside the interrogatories.¹	A formal notice of objection must be delivered and filed, setting out concise grounds and potential alternative means of response.⁶
Enforcement	Application to the court for an order to answer or answer further, with no specific timeline for the application.¹	Application to compel must be made within 14 days of receiving the response (or the expiry of the time for response).¹⁷
Costs Sanctions	General discretion for the court to penalise unreasonable interrogatories in costs.¹	Specific power for the court to order that costs of unreasonable interrogatories be paid “in any event” by the offending party.¹⁷

Part IV: Harmonisation of Procedure: The Extension to the Circuit Court (S.I. No. 200 of 2025)

The transformative approach to interrogatories was not confined to the High Court. Less than a year after the Superior Court rules were reformed, the procedural modernisation was extended to the Circuit Court through the introduction of S.I. No. 200 of 2025, the Circuit Court Rules (Interrogatories) 2025, which came into operation on 13 June 2025.²¹ This development, far from being a mere afterthought, represents a crucial and deliberate step in a broader strategy to enhance the efficiency and consistency of civil procedure across the Irish court system.

A Mirror Image of the High Court Reforms

The new Circuit Court rules on interrogatories are, for all practical purposes, a direct replica of the High Court reforms enacted by S.I. No. 363 of 2024. This mirroring of the rules was clearly intentional, aimed at creating a harmonised procedural environment. The key features introduced into the Circuit Court procedure include:

A “Leave-Free” Quota: Just as in the High Court, a party in a Circuit Court action may now deliver one set of up to 20 interrogatories to another party without the prior leave of the Court or the County Registrar.²¹ This can be done at any time after the delivery of the Civil Bill or Defence, but prior to the service of a Notice of Trial.²¹
Identical Drafting Requirements: The new Circuit Court rules import the same strict drafting requirements that now govern High Court interrogatories. Questions must be accompanied by a statement of necessity, be confined to questions of fact rather than evidence, relate to matters likely to be within the responding party’s knowledge, and be amenable to a short, factual answer.²¹
Harmonised Response and Objection Protocols: The new rules establish the same procedural framework for responding. The interrogated party has 21 days to provide a sworn affidavit in response and/or to file a notice of objection setting out concise grounds and any proposed alternative means of addressing the query.²¹
Consistent Enforcement Mechanisms: The enforcement procedure is also aligned. The interrogating party has 14 days from the receipt of an unsatisfactory response to apply to the Court or County Registrar to compel an answer. The court is granted the same wide powers to make orders and to penalise unreasonable interrogatories with adverse costs orders.²¹

The Wider Strategy: Rebalancing the Court System

The decision to extend these modernised rules to the Circuit Court must be viewed in the context of the wider judicial discourse on the structure and efficiency of the Irish courts. Senior judges, notably Mr. Justice Twomey, have criticised what they see as an “inversion” of the traditional court pyramid, where the number of cases being litigated in the expensive High Court has grown disproportionately compared to the more affordable Circuit Court.²² This phenomenon has been attributed, in part, to a perception that the procedural toolkit available in the lower courts is less robust, driving litigants with claims that might otherwise be suitable for the Circuit Court towards the High Court. This trend has significant implications for access to justice, as it can lead to situations where the legal costs of a dispute become disproportionate to the value of the claim itself.²²

The harmonisation of the interrogatories procedure is a direct and practical response to this problem. By equipping the Circuit Court with the same modern, efficient, and powerful procedural tool that is now available in the High Court, the Rules Committee has taken a significant step towards levelling the procedural playing field. This move is not merely about administrative tidiness; it is a strategic initiative designed to rebalance the justice system.

It makes the Circuit Court a more attractive and viable forum for the resolution of disputes that fall within its jurisdiction. It removes a potential incentive for litigants to initiate proceedings in the High Court simply to gain a perceived procedural advantage. By encouraging litigants to bring their claims in the appropriate, lower-cost forum, the reform promotes the principle of proportionality and helps to control the overall costs of litigation, not just within a single case, but across the entire civil justice system. This deliberate strategy of procedural harmonisation is therefore a key component of the broader effort to ensure that access to justice in Ireland is efficient, effective, and proportionate to the nature and value of the dispute.

Part V: Strategic and Practical Guidance for the Legal Practitioner

The 2024-2025 reforms have fundamentally altered the strategic landscape of Irish civil litigation. Interrogatories have been transformed from a rarely used, specialist device into a mainstream, front-line tool that must be considered in the strategic planning of almost every case.⁶ For the legal practitioner, mastering the offensive deployment of interrogatories and the defensive response to them is no longer an option, but a necessity. This requires a shift in mindset, moving from a discovery-centric approach to one that prioritises early, targeted factual clarification.

Offensive Strategy: Drafting and Deploying Interrogatories

The new rules empower the proactive litigator. Used effectively, interrogatories can shape the battlefield of the litigation from a very early stage.

When to Use Them

The optimal time to deploy interrogatories is typically soon after the close of pleadings. At this point, the broad contours of the dispute are defined, but the precise factual disagreements are often obscured by formal and sometimes vague language. Serving interrogatories at this juncture allows a party to achieve several key objectives: to obtain crucial admissions that weaken the opponent’s case, to force the other side to commit to a specific factual narrative on oath, to narrow the issues in dispute, and, critically, to define and limit the scope of any subsequent discovery process, thereby saving significant time and cost.⁶

The Art of the “20 Best Questions”

The 20-question leave-free limit is both a right and a restriction. It forces practitioners to engage in a rigorous process of strategic selection. It is not an opportunity for a “fishing expedition”.²³ Instead, the litigator must meticulously analyse the pleadings and identify the 20 most critical factual questions, the answers to which will have the greatest impact on the case.⁶ This requires a deep understanding of the core strengths and weaknesses of both their own and their opponent’s case. The focus must be on questions that can dismantle a key plank of the opposing claim or defence, or establish an essential element of one’s own.

Drafting Best Practice

The effectiveness of interrogatories is directly proportional to the quality of their drafting. Under the new rules, poorly drafted questions will be met with successful objections. The guiding principles for drafting are clarity and compliance with Rule 2:

Clarity: Questions must be “crystal clear” and unambiguous.¹⁸ Confusing or compound questions are likely to be struck out.
Fact, Not Law or Evidence: As established in Ryan v Haq, questions must seek factual information, not legal conclusions or opinions.²⁰ A question like “Did the defendant breach its duty of care?” is impermissible. A question like “Was a warning sign present at the entrance on 5 March 2024?” is permissible. Similarly, questions must not seek the evidence by which a fact will be proven.⁴
Relevance: As demonstrated in Kiely v U2, interrogatories must be directly relevant to the matters pleaded. Questions about extraneous or scandalous matters will be struck out, and may result in a costs penalty.⁸
Eliciting a Short Answer: Questions should be framed to elicit a “yes,” “no,” or a very brief factual statement, such as a date, a name, or a quantity.⁶

Targeting Vague Pleadings and Obtaining Admissions

One of the most powerful applications of the new regime is as a weapon against the “blanket defence”.³ Where a defendant has delivered an uninformative defence that simply puts the plaintiff on proof of all matters, a series of targeted interrogatories can force the defendant to go on affidavit and either admit or deny specific factual assertions. This prevents the defendant from keeping their options open until trial and helps to crystallise the real issues in dispute.

Furthermore, answers to interrogatories are sworn evidence and can be put to the court at trial.¹⁸ A key strategic goal is therefore to obtain admissions on essential facts. For example, in the data breach case of

Nolan v Dildar & Ors, the defendant admitted in interrogatories that he had disclosed the plaintiffs’ personal data without their permission, an admission which became a central plank of the court’s finding of liability against him.²⁴

Defensive Strategy: Responding and Objecting

For the practitioner on the receiving end of interrogatories, a careful and strategic response is equally crucial.

The Gravity of the Affidavit

The first duty of the solicitor is to impress upon their client the seriousness of the answering affidavit. The answers are given on oath and are binding on the party.¹⁸ An incorrect answer, whether given deliberately or carelessly, can have severe consequences for the client’s credibility and the outcome of the case. If an error is made, it must be corrected, and this may require a detailed explanation to the court as to how the error arose.²⁶ The person swearing the affidavit, typically a director or company secretary in the case of a corporate body, must be advised that they have a positive duty to make “reasonably necessary inquiries” to ascertain the correct facts before swearing the document.¹⁸

Formulating Valid Objections

The new rules provide a clear framework for objecting to improper interrogatories. A responding solicitor should meticulously review each question against the strict criteria of Rule 2. Valid grounds for objection are now easier to formulate and argue. Common and strong objections will include:

The question does not comply with Rule 2 (e.g., it seeks an opinion, a legal conclusion, or evidence).
The question is not “necessary” for disposing of the matter or saving costs.
The question is a “fishing expedition,” vexatious, or oppressive.
The question is not sufficiently material at the current stage of the proceedings.¹⁸

The Strategic Use of “Alternative Means”

The new objection procedure contains a powerful strategic tool for the responding party. When objecting, the party can proactively offer to address the substance of the query through “alternative means”.¹⁹ For example, in response to a clumsily worded interrogatory about a company’s policy, the solicitor could object to the form of the question but offer to produce the relevant policy document as an alternative. This allows the party to appear reasonable and cooperative, satisfying the spirit of the inquiry and reducing the likelihood of a successful application to compel, while simultaneously avoiding being trapped by the precise wording of a potentially problematic question.

The following checklist is designed as a practical tool for practitioners drafting interrogatories under the new regime.

Checklist Item	Relevant Rule (RSC)	Practitioner’s Note
Is this the first set of interrogatories being delivered to this party?	O.31, r.3(a)	If ‘No’, an application to the Court for leave is required.
Is the total number of individual questions 20 or fewer?	O.31, r.3(a)	If more than 20, leave of the Court is required. Prolixity is a ground for objection.
Does each question/group of questions have a brief statement of necessity?	O.31, r.2(3)	Failure to include this is a clear ground for objection. State why the answer is necessary for fair disposal or saving costs.
Does each question seek to elicit a FACT, not evidence, opinion, or a legal conclusion?	O.31, r.2(4)(a)	This is a crucial distinction. Reference Ryan v Haq. Avoid “why” or “how” questions; focus on “what,” “when,” “who,” “where.”
Is each question capable of a “yes,” “no,” or short factual statement answer?	O.31, r.2(4)(c)	Avoid questions that invite or require a narrative response.
Is the information sought likely to be within the responding party’s knowledge after reasonable inquiries?	O.31, r.2(4)(b)	Avoid pure speculation. The question must be grounded in the reality of the party’s operations.
If serving a corporate body, has the correct person to answer been identified?	O.31, r.2(2)	The default is the company secretary. If a specific officer is required, an application to court may be necessary.
Have the interrogatories been copied to every other party to the proceedings?	O.31, r.2(1)	This is a new procedural requirement to ensure all parties are informed.
Have the relevant deadlines been diarised?	O.31, r.4 & r.7	Diarise the 21-day deadline for the response, and the subsequent 14-day deadline to apply to compel an answer if the response is unsatisfactory. These are strict time limits.

Part VI: The Future of Pre-Trial Disclosure and Cost Management in Ireland

The 2024-2025 reforms to the rules on interrogatories are more than a technical adjustment to civil procedure; they signal a significant shift in the judicial philosophy underpinning pre-trial disclosure in Ireland. They represent a pragmatic and determined effort to inject proportionality, efficiency, and cost-effectiveness into a system that was groaning under the weight of the “discovery monster.” While this targeted intervention is a profoundly positive development, it is one piece of a much larger puzzle. The future of civil litigation in Ireland will be shaped by how these new tools are used, the cultural changes they engender among practitioners, and the progress of other, wider reforms that are still required.

The Likely Impact on Litigation Costs

The primary policy objective behind the reforms is to reduce the exorbitant costs associated with civil litigation.⁵ The optimistic view is that the new rules will achieve this by promoting the early narrowing of issues, which in turn will drastically reduce the scope, and therefore the cost, of the discovery process.⁶ By obtaining key admissions or clarifications on oath at the outset, parties can avoid the need for extensive, and expensive, trawls through vast quantities of electronic data. This aligns with the broader policy goal of controlling legal costs, which have been criticised by the courts for often exceeding the value of the underlying claim.¹⁵

However, a more cautious perspective suggests that while the reforms may reduce costs in one area, they may increase them in another. The new regime necessitates a significant “front-loading” of costs.⁶ Practitioners will now need to invest more senior solicitor and counsel time at the very beginning of a case to conduct a deep analysis of the pleadings and meticulously draft a set of strategic, compliant interrogatories. This contrasts with the old model where much of the heavy lifting of discovery could be delegated to more junior staff later in the process. Furthermore, the new rules will inevitably create a new procedural battleground. It is highly likely that there will be a surge in interlocutory applications to compel answers and disputes over the precise interpretation of the new Rule 2 requirements—for instance, what is truly “necessary,” or where the line between “fact” and “evidence” lies.¹⁸ This satellite litigation could offset some of the savings gained from reduced discovery.

The Unresolved “Discovery Monster” and the Path Forward

It is crucial to acknowledge that the interrogatories reform, while significant, is not the comprehensive overhaul of discovery that was envisioned by the Kelly Report. The “monster” has been challenged and wounded, but it has not been slain.¹¹ The fundamental, 19th-century rules governing the discovery process itself remain in place. The reforms provide a powerful alternative route for information gathering, but in cases where broad discovery is ultimately still deemed necessary, the underlying problems of cost and scale persist. The need for the Oireachtas to act on the substantive recommendations of the Kelly Report and to legislate for a modern, 21st-century disclosure regime remains as pressing as ever.

The interrogatories reform should therefore be seen as part of a broader ecosystem of ongoing and proposed changes to the Irish civil justice system. These include:

The introduction of pre-action protocols, particularly in specialised areas like clinical negligence, which require parties to exchange information and attempt resolution before proceedings are even issued.²⁷
The establishment of dedicated court lists, such as the new Clinical Negligence List, which benefit from enhanced, proactive case management by experienced judges.²⁷
The development of a formal mechanism for multi-party or group litigation, which will allow for the efficient management of cases involving multiple claimants with similar claims.¹⁰

These initiatives, taken together, point towards a clear future direction for Irish civil justice: one that prioritises early engagement, active case management, and proportionality at every stage of the process.

A Forced Skill Shift in Legal Practice

Perhaps the most profound and lasting impact of the new interrogatories regime will be the cultural and economic shift it forces upon legal practice. The reforms will change not just what litigators do, but how and when they do it. The traditional litigation model, often characterised by a slow build-up to a massive, document-heavy discovery exercise late in the proceedings, is now challenged. The new emphasis is on intense, front-loaded strategic analysis. Success in litigation will increasingly depend on the ability to identify the core issues and craft surgical, precise questions at the outset.

This necessitates a fundamental skill shift. The value of a litigator will be measured less by their capacity to manage a large-scale document review and more by their analytical ability to dismantle an opponent’s case with 20 well-aimed questions. This has significant implications for law firms’ business models and training programmes. More partner-level and senior associate time will be required at the start of a file. The economic model of leveraging large teams of junior fee-earners for discovery may become less prevalent. Consequently, the training of junior solicitors must evolve to focus on developing high-level analytical, strategic, and drafting skills much earlier in their careers. In the competitive Irish legal market ³², firms that adapt quickly to this new reality and demonstrate a mastery of these front-loaded, strategic tools will gain a significant competitive advantage.

In conclusion, the 2024-2025 reforms to interrogatories are a landmark development in Irish civil procedure. They are a bold and necessary step towards creating a more modern, proportionate, and efficient justice system. While not a panacea for all the ills of pre-trial procedure, they provide judges and practitioners with a vital tool to manage litigation more effectively and to control its spiralling costs. Their ultimate success will depend on a collective embrace of the cultural shift they demand—a move away from the attritional warfare of discovery towards a more focused, intelligent, and strategic approach to the resolution of civil disputes.
