Proportionate discovery in employment-contract litigation: authority/ratification documents ordered; comparator pay discovery refused absent pleaded basis

1. Introduction

Nowak v Intesa San Paolo Vita S.P.A (Approved) [2026] IEHC 383 is a High Court discovery decision (O’Donnell J.) on appeal from the Deputy Master. The underlying dispute arises from the plaintiff’s dismissal in 2015 and her claim for (i) damages for breach of contract and (ii) additional relief including a declaration that termination was invalid and reinstatement. The case shares the same factual background as [2026] IEHC 382, where the Court addressed jurisdictional issues in related unfair-dismissal litigation.

The application concerned discovery under Order 31, rule 12. The plaintiff (acting in person) sought four categories of documents, broadly aimed at: (a) the authority and process for the disciplinary/termination decision, and (b) comparator pay and employment information to support an asserted “equal pay” aspect of the contractual remuneration-review claim.

Key issues

  • Whether the documents sought were relevant and necessary to the pleaded issues, applying proportionality and the prohibition on “fishing”.
  • How to handle discovery requests implicating confidential information of non-parties (named colleagues).
  • Costs where an applicant in person is partly successful, in light of s. 169 of the Legal Services Regulation Act 2015.
  • Whether discovery should be deferred pending a possible application that could render discovery unnecessary.

2. Summary of the Judgment

The High Court allowed the appeal in part and substituted a narrower, issue-focused order:

  • Granted: discovery of documents evidencing the process by which the defendant decided to terminate the plaintiff’s employment, including documents evidencing any authority/instructions to persons conducting the process and any ratification of the decision by the defendant’s CEO (a director).
  • Granted (limited): discovery of documents from 2009 to 2015 evidencing any review of the plaintiff’s remuneration (reflecting the pleaded contractual term on review for “merit and cost of living”).
  • Refused: broad comparator discovery (including P45/P60 and educational qualifications of four named colleagues), as not necessary or clearly relevant on the pleaded case, and as disproportionately intrusive into non-party confidentiality.

On costs, the Court awarded the plaintiff 75% of the costs (as may be due to an applicant in person) of the Deputy Master application and the High Court appeal, to be adjudicated if not agreed, and stayed pending the outcome of the overall proceedings.

The Court did not set a deadline for the affidavit of discovery, listing the matter for a short further hearing to consider whether discovery should be deferred in light of the defendant’s indication that it might bring an application that could dispose of or curtail the proceedings.

3. Analysis

3.1 Precedents cited and their influence

(a) Tobin v. Minister for Defence [2020] 1 I.R. 211

The Court treated Tobin as part of the modern, appellate-level guidance confirming that discovery under Order 31, rule 12 remains anchored in relevance to pleaded issues and necessity, now strongly inflected by proportionality. While the judgment did not re-derive the Tobin principles at length, it positioned the present decision as a routine application of those established constraints.

(b) Ryan v. Dengrove DAC [2022] IECA 155

Dengrove supplied the operative “checklist” applied by O’Donnell J., including that:

  • Relevance is assessed by reference to pleadings and particulars.
  • Relevance must be shown as a matter of probability, not possibility.
  • A party cannot seek discovery to see if something might be relevant (“fishing”).
  • Vague or unparticularised allegations cannot justify broad discovery.
  • “Necessity” is informed by the strength of relevance.
  • Proportionality requires a relationship between volume/intrusion and likely forensic value.

The structure of the outcome maps directly onto Dengrove: the Court granted discovery where pleadings put authority/process in issue, but refused expansive comparator material where the pleadings did not articulate a concrete, particularised comparator-based claim.

(c) Hannon v Commissioner of Public Works [2001] IEHC 59

The Court adopted the Hannon proposition (as quoted in Dengrove) that discovery is not ordered merely because documents might be relevant. This was central to rejecting the comparator category, which the Court viewed as exceeding what could be justified by the limited “equal pay” pleading.

(d) O'Brien v. Red Flag Consulting Limited [2021] IECA 258

O'Brien informed two linked points:

  • a party cannot seek discovery to determine whether a document is relevant; and
  • proportionality requires a balance between the breadth of discovery and its likely value.

Those points were particularly salient because the refused request sought extensive payroll/tax and educational documentation about identified non-parties.

(e) Boehringer Ingelheim Pharma GmbH v. Norton (Waterford) Ltd [2016] IECA 67

The Court relied on the proposition that “necessity” is not binary: the degree and “potential strength” of relevance matters. This underpinned the Court’s decision to reformulate discovery—ordering narrower categories squarely tied to the pleaded authority/ratification and remuneration-review issues.

3.2 Legal reasoning

(a) The “authority/process” categories (granted, but reformulated)

The plaintiff alleged that the person who ran the process and signed the termination letter lacked authority (pleaded as ultra vires/invalid process), and further alleged inadequate reporting to the board. The defendant joined issue, pleading (i) a fair process, (ii) that the process was disciplinary rather than “investigatory” in the manner characterised by the plaintiff, and (iii) that the plaintiff acquiesced and was estopped from disputing authority, with an alternative reliance on ratification by the CEO/director.

O’Donnell J. treated these as live pleaded controversies where documentary proof is inherently likely to exist (corporate governance/decision-making records). Importantly, the Court refused to decide, at discovery stage, whether the plaintiff had “misconstrued the process”. That question was itself in dispute and not determinable on the limited record.

The Court therefore ordered discovery not in the exact terms sought, but as a more functional category: documents evidencing (i) the process leading to termination, (ii) authority/instructions to those conducting it, and (iii) any CEO ratification. This is a characteristic proportionality move: the Court ensured access to the key forensic materials while avoiding over-specific or potentially misdirected sub-categories.

(b) The comparator pay/qualification category (refused)

The plaintiff’s pleading focused on an alleged contractual failure to review and adjust her pay for “merit and cost of living” over specified years, with a brief reference to “equal pay obligations”. The Court found no pleaded factual framework connecting that assertion to particular comparators or to a coherent claim requiring disclosure of those individuals’ private employment and tax records.

Two considerations converged:

  • Pleading-driven relevance: without particulars tying comparators to a concrete issue, the request looked like an attempt to see whether some useful comparator case might emerge—i.e. “fishing”.
  • Non-party confidentiality and proportionality: the request sought extensive private information of identifiable non-parties. The Court emphasised that confidentiality is not an absolute bar to discovery, but it heightens the need for strict scrutiny of relevance/necessity.

Instead, the Court granted a narrower alternative: documents evidencing any review of the plaintiff’s remuneration (2009–2015), aligning tightly with the pleaded contractual review term.

(c) Timing: discovery potentially rendered unnecessary

The defendant argued discovery might be premature if it later brought an application capable of terminating the plenary proceedings (in light of the parallel unfair-dismissal jurisdiction path addressed in [2026] IEHC 382). The Court declined to refuse discovery on a hypothetical application, but adopted a pragmatic case-management step: it made the discovery order yet deferred fixing the time for the affidavit, listing the matter for further short argument.

This approach preserves the plaintiff’s entitlement to necessary discovery while mitigating the risk of wasted cost if a dispositive application is promptly brought.

(d) Costs: partial success and litigant in person

The Court’s costs reasoning balanced competing conduct factors:

  • the motion was issued despite a not-unreasonable request for additional time during the long vacation; but
  • the defendant filed no replying affidavit and maintained a blanket refusal rather than proposing a narrower, defensible discovery formulation.

Applying s. 169 LSRA 2015, the plaintiff received 75% of the costs (as may be due to an applicant in person) of both the Deputy Master stage and the appeal, stayed pending the outcome of the proceedings.

3.3 Impact

  • Comparator discovery discipline: the decision reinforces that broad comparator-based requests—especially involving payroll/tax and educational records of non-parties—will likely fail absent a clearly pleaded, particularised comparator issue linking the documents to a live dispute.
  • Corporate authority and ratification: where termination validity is challenged on authority/process grounds, discovery will generally be ordered for documents evidencing governance, delegation, and ratification—often the core evidential trail in corporate employment dismissals.
  • Proportionate reformulation: the Court’s willingness to recast categories into an issue-based formulation illustrates an increasingly managerial approach to discovery, consistent with Dengrove and the broader proportionality trend.
  • Case-management on “potentially dispositive” applications: making an order but deferring the affidavit timetable provides a template for avoiding unnecessary discovery costs without denying meritorious discovery outright.
  • Costs signals: a party opposing discovery risks adverse costs consequences where it offers no evidence (no replying affidavit) and no constructive narrowing proposal, even if the applicant’s request is partly overbroad.

4. Complex concepts simplified

  • Discovery (Order 31, rule 12): a pre-trial process requiring a party to disclose documents relevant and necessary to resolve the issues in the case.
  • Relevance vs necessity: a document can be relevant but still not necessary to order (e.g., marginal value, excessive burden, or disproportionate intrusion).
  • Proportionality: the scope of discovery should match the likely value of the documents to the case; the broader and more intrusive the request, the stronger the justification needed.
  • Fishing expedition: seeking documents not because they are probably relevant to a pleaded issue, but to see if something useful turns up.
  • Ultra vires / lack of authority: a contention that a person acted outside the powers given to them, potentially making a decision (such as dismissal) invalid.
  • Ratification: later approval of an act (e.g., dismissal) by a person/body with authority, which may cure an earlier defect in authority (depending on context and law).
  • Estoppel by acquiescence: a defence that a party who went along with a process cannot later challenge it, where fairness and reliance factors are satisfied.

5. Conclusion

[2026] IEHC 383 reaffirms a pleading-led, proportionate approach to discovery in employment-contract litigation. The High Court compelled discovery of documents evidencing the termination decision-making process, delegation/authority, and alleged CEO ratification—core materials for determining whether dismissal was effected with proper corporate authority. It refused expansive comparator pay/qualification discovery affecting non-parties where the pleadings did not clearly put comparator-based equal pay issues in dispute, granting instead a narrower order tied to the plaintiff’s own remuneration-review allegation. The decision also highlights that blanket opposition without evidence or narrowing proposals can drive adverse (though proportionate) costs consequences, including for litigants in person under s. 169 LSRA 2015.
