Wheelock v. Promontoria & Anor

Factual and Procedural Background

The Plaintiff previously sued his accountant for fraud, alleging that forged documents and unauthorised agreements left him with debts of approximately €2.67 million and a mortgage over lands in The City. That earlier claim settled for €1.5 million paid by the accountant’s insurers.

In 2014, Company B began judgment proceedings against the Plaintiff. The first-named Defendant (“Company A”) was later substituted into those proceedings and, in 2018, appointed the second-named Defendant as receiver over the same lands. The Plaintiff then initiated plenary proceedings contending that the mortgage deeds were void because they were obtained through fraud or mistake. The Defendants counter-claimed for unjust enrichment, asserting that the Plaintiff benefitted from any increase in the land’s value.

During discovery, the Plaintiff sought fifteen categories of documents. Category 13 requested all documents evidencing the price paid by Company A when it acquired the loan and mortgage. The High Court (ex tempore) refused discovery of that category. On 12 March 2021 the Court of Appeal reversed that decision, ordered discovery of Category 13, and made no order as to costs. The Defendants now seek leave to appeal; the Plaintiff opposes that application and cross-applies on the costs issue.

Legal Issues Presented

1. Whether the purchase price paid by the Defendants for the loan and mortgage is “relevant and necessary” so as to justify discovery in proceedings involving an unjust enrichment counter-claim.
2. Whether, even if discovery is appropriate, it should be limited to disclosure ordered only after the trial judge deems the information necessary for quantification.
3. Whether the Court of Appeal erred in making no order as to costs following its discovery ruling.
4. More broadly, whether these questions raise matters of general public importance warranting Supreme Court intervention under Article 34.5.3° of the Constitution.

Arguments of the Parties

Defendants’ Arguments

• The Court of Appeal erred in treating the purchase price as relevant or necessary; it failed to identify any unfairness that would arise were the Plaintiff to proceed to trial without that information.
• If discovery is to be granted, inspection should occur only if and when the trial judge considers it necessary for assessing unjust enrichment.
• The matter is of general public importance because numerous borrowers seek this commercially sensitive information in similar litigation, and clear guidance is required.
• The Court of Appeal imposed inspection restrictions without adequate submissions; interests of justice therefore require Supreme Court review.

Plaintiff’s Arguments

• The discovery issue is fact-specific and does not give rise to any question of general public importance.
• The Court of Appeal’s ruling aligns with existing authority, notably Promontoria (Aran) Ltd v Sheehy, and no injustice to the Defendants has been demonstrated.
• The Plaintiff cross-appeals on costs, contending that the Court of Appeal erred in refusing him his costs and that this has general application to costs decisions in other cases.

Court's Reasoning and Analysis

The Supreme Court emphasised that, although discovery rulings are interlocutory and ordinarily unfit for appeal, the present application raises broader questions touching on discovery principles, unjust enrichment doctrine, and the obligations of investment funds to disclose purchase-price information to debtors. The Court observed that existing case law and commentary reveal differing views on these issues and that the matter could affect numerous similar cases.

It further noted that the Court of Appeal had criticised the High Court for resolving substantive issues of unjust enrichment at a discovery motion and acknowledged that alternative legal analyses exist. Given the potential impact on commercial lending litigation and the need to clarify appropriate safeguards when commercially sensitive data are disclosed, the Supreme Court considered the appeal to involve matters of general public importance and the interests of justice.

Regarding the Plaintiff’s cross-appeal on costs, the Court observed that the Court of Appeal had invited the parties to seek a costs hearing if dissatisfied. Whether that invitation was taken up will be examined at a case-management stage; consequently, the Supreme Court deemed it appropriate to grant leave on the costs question as well.

Holding and Implications

LEAVE TO APPEAL GRANTED to the Defendants, and LEAVE TO CROSS-APPEAL GRANTED to the Plaintiff, with the precise issues to be refined at a case-management hearing.

Immediate effect: the discovery and costs rulings of the Court of Appeal are now subject to full appellate review. Broader implications: the forthcoming appeal may clarify (a) when purchase-price discovery is required in unjust enrichment cases, (b) the limits that may be imposed to protect commercially sensitive information, and (c) guiding principles on costs where interlocutory discovery orders are contested. No new substantive precedent has yet been set; the determination merely opens the door for further consideration.
