Execution After Six Years Requires a Reasonable, Evidence-Based Explanation of Delay

1. Introduction

This judgment draws an important distinction between owning a judgment debt and obtaining permission to execute it after six years. Mars Capital Finance Ireland Designated Activity Company established that it had acquired the benefit of a judgment originally obtained by AIB Mortgage Bank. However, it failed to provide sufficiently specific evidence explaining the prolonged absence of execution. The High Court therefore substituted Mars as plaintiff but refused leave to execute.

The underlying judgment, obtained in November 2017, concerned an unpaid mortgage loan. The defendants did not challenge the correctness of that judgment and consequently admitted their indebtedness under it. The disputed questions were whether the loan transfer carried the existing judgment with it and whether Mars had reasonably explained the delay in enforcement.

The decision’s principal contribution is evidential rather than a wholesale change in enforcement law: although the threshold for explaining delay is low, general assertions about negotiations, portfolio assessment, the pandemic and receivership do not necessarily satisfy it. The judgment also exposes an unresolved conceptual tension in Irish law concerning the merger of a contractual debt into a judgment.

2. Background and Procedural History

A foundational distinction runs throughout the judgment: the 2017 proceedings were a money claim, not an action to enforce the mortgage. The loan obligation, the resulting money judgment and the mortgage security were related, but their enforcement raised different legal questions.

3. Summary of the Decision

• Substitution granted: Mars had acquired the benefit of the judgment and could replace AIB Mortgage Bank as plaintiff under Order 17, rule 4.
• Leave to execute refused: Mars had not reasonably explained substantial periods of non-execution through sufficiently particularised evidence.
• No requirement for exceptional reasons: the established low threshold remained applicable, but it still required a reasonable explanation supported by evidence.
• Settlement privilege did not prevent proof of negotiations: their occurrence and timing could be established to explain delay without ordinarily revealing offers or admissions.
• Costs remained provisional: the court proposed awarding the defendants half their motion costs, subject to the parties’ opportunity to be heard before perfection of the order.

The refusal did not invalidate the judgment or reverse the finding that Mars owned it. It concerned permission to execute on the application and evidence before the court.

4. Assignment of the Judgment: Precedents and Legal Reasoning

4.1 Proof of transmission remained necessary

Under Order 17, rule 4, a change or transmission of interest after proceedings commence may justify introducing or substituting a party. Relying on Bank of Scotland v McDermott [2019] IECA 142, the court accepted that substitution applications should not become miniature trials. Nevertheless, Mars had to prove, on the balance of probabilities, that the benefit of the judgment had passed to it. The procedural character of the application did not dispense with proof of title.

4.2 The merger problem

The transfer deed assigned the loan and broadly defined associated rights, but did not expressly assign the existing judgment. That omission raised the doctrine of merger: once a creditor obtains a final money judgment on a contractual debt, what remains available for assignment?

The English authorities examined by Holland J describe merger as a substantive and automatic legal consequence, not a discretionary rule. The original cause of action is extinguished and replaced by the right to enforce the judgment.

• Zavarco plc v Nasir [2021] EWCA Civ 1217 provided the principal review of the doctrine. Merger applies where an obligation under the cause of action is embodied in and replaced by a final court order. A merely declaratory judgment does not necessarily have that effect.
• Virgin Atlantic Airways Ltd v Zodiac Seats UK Ltd [2013] UKSC 46, [2014] AC 160 explained that, following judgment, the claimant’s sole right is upon that judgment rather than the extinguished cause of action.
• Clarke v In Focus Asset Management and Tax Solutions Ltd [2014] EWCA Civ 118, [2014] 1 WLR 2502 emphasised the resulting prohibition on bringing fresh proceedings to enforce the original cause of action.
• Letang v Cooper [1965] 1 QB 232 supplied the definition of a cause of action as a factual situation entitling one person to obtain a judicial remedy against another.
• Director-General of Fair Trading v First National Bank plc [2001] UKHL 52, [2002] 1 AC 481 treated the principal debt, after judgment, as owed under the judgment rather than the contract. It also illustrated how appropriately drafted interest provisions can survive merger.
• In re Sneyd; Ex p Fewings (1883) 25 Ch.D 338 formed part of the historical foundation for that understanding, discussed through the later authorities.

The subsequent Supreme Court decision in Zavarco plc v Nasir [2025] UKSC 5 substantially endorsed the Court of Appeal’s reasoning. Holland J regarded its explanation as reinforcing the conceptual difficulty of treating the loan as surviving independently of the extinguished cause of action.

These authorities prompted a direct question: if the contractual debt has been replaced by a judgment debt, is an assignment expressed only by reference to the loan sufficient? Holland J considered that the problem could readily have been avoided by expressly assigning existing judgments.

4.3 The controlling Irish authorities

Despite those reservations, the court applied Irish precedent rather than adopting a conflicting understanding of merger.

Ulster Bank v Quirke

Ulster Bank v Quirke [2022] IECA 283 was central. It held that an unpaid loan continues to exist notwithstanding the extinguishment of its cause of action by judgment. The loan and judgment are, in effect, one, so assignment of the former transfers the latter even without expressly mentioning it.

This was not simply an interpretation of particular contractual wording: it addressed the legal effect of assigning a loan after judgment. As that reasoning supported the order joining the assignee, Holland J regarded it as binding, while examining whether the assignee’s separate failure to obtain leave to execute affected its status as an essential part of the decision.

The later decision, Ulster Bank Ltd v Quirke [2023] IECA 139, acknowledged the possible utility of ownership for registering a judgment mortgage. It supported the view that joinder was not necessarily pointless merely because execution had been refused. The present judgment did not resolve whether registration of a judgment mortgage constitutes execution.

AIB & Everyday v McKeown

In AIB & Everyday v McKeown [2021] IEHC 499, transfer of the underlying facilities and guarantees supported substitution of the assignee following judgment. Express transfer of the court order was considered unnecessary.

Holland J nevertheless identified an important limitation: the argument rejected there was that transferring the loans had extinguished the judgment, rather than that merger had already extinguished the contractual debt. The judgment did not discuss merger. It therefore provided less direct analysis of the present conceptual problem than its later use might suggest.

Permanent TSB & Anor v. Beades

Permanent TSB & Anor v. Beades [2021] IECA 48 concerned a possession order following the transfer of mortgage interests. Broad wording assigning the seller’s rights and associated claims was interpreted as carrying the benefit of that order.

The case demonstrated that an existing enforcement order could travel with the transferred rights. However, it too did not analyse merger. Holland J accordingly distinguished its contractual interpretation reasoning from a fully examined resolution of whether a contractual loan survives a money judgment.

AIB v Sheedy

In AIB v Sheedy [2024] IEHC 145, [2025] IECA 124, the High Court expressly applied the Irish authorities to hold that assignment of a loan after judgment transfers the judgment without its specific inclusion in the deed.

Holland J carefully noted that this finding was not challenged at the Court of Appeal hearing. The appellate judgment should therefore not be overstated as a fresh determination, after full argument, of the merger issue. Nevertheless, the High Court decision supplied a further basis for following the established Irish position.

4.4 An alternative route: interpretation of the documents

Even if assignment of the loan did not automatically transfer the judgment, the court considered the wording sufficient under the approach in Harte v Promontoria Aran & Ors. [2023] IEHC 593.

That decision accepted that the contractual debt had merged in the judgment but concluded that broad assignment language nevertheless included the judgment debt. Particularly significant was the express inclusion of “Ancillary rights and claims”. Although decided in an interlocutory injunction application, its conclusion was that the borrower had raised no serious issue on whether the judgment had been assigned, rather than merely that one outcome was provisionally more likely.

In the present documents, the deed incorporated definitions from the mortgage sale agreement. These extended to amounts outstanding “under or in connection with” the loans and to claims and rights based upon, arising out of or related to the mortgage assets. Holland J could identify no material distinction from Harte v Promontoria Aran & Ors..

Re Worldport Limited [2005] IEHC 189 supplied the principles governing adherence to decisions of another High Court judge. Holland J considered himself bound on that basis by the relevant High Court authorities if the Court of Appeal decision did not independently determine the matter.

4.5 Holding and reservation must be separated

The operative holding was that Mars acquired the judgment. The court did not hold that merger defeated the assignment, nor did it displace the Irish authorities.

Its reservations were nevertheless substantial. Holland J questioned the conceptual distinction between a surviving loan and an extinguished cause of action on that loan, and invited appellate consideration with full argument on the English authorities. Those observations identify an issue for future clarification; they are not a contrary rule established by this judgment.

5. Leave to Execute: A Low Threshold with Real Evidential Content

5.1 The governing authorities

Order 42, rule 24 requires leave where six years have elapsed since judgment or there has been a relevant change in the parties entitled or liable to execution. The decision is discretionary.

The court drew the applicable principles from Smyth v Tunney [2004] 1 IR 512, Bula Limited (in Receivership) v. Tara Mines Ltd. [2008] IEHC 437, Cabot Financial (Ireland) Ltd v Joyce [2023] IECA 281 and Ulster Bank v Quirke [2022] IECA 283:

1. Execution rules are facilitative. They generally exist to make established rights effective, not to frustrate them.
2. Exceptional circumstances are unnecessary. A creditor need not produce unusual or very special reasons, or justify the delay in the sense of proving that every decision was necessary.
3. A reasonable explanation is still required. Expressions such as “good”, “sufficient” or “acceptable” explanation reflect that requirement of reasonableness.
4. The relevant period begins with judgment. The creditor must address the lapse of time from judgment to the point at which leave is sought, not merely the period after the initial six years. The majority approach in Cabot Financial (Ireland) Ltd v Joyce supported this requirement.
5. Prejudice becomes a balancing question once the explanatory threshold is crossed. A reasonable explanation does not automatically secure leave if countervailing prejudice outweighs the creditor’s interest.

The public interest favours constructive engagement with debtors. Creditors should not be discouraged from negotiating by a rule effectively requiring immediate execution. Equally, that policy does not remove the need to demonstrate that negotiations actually explain the period relied upon.

5.2 Explanation is different from justification

A creditor may reasonably prefer negotiations, receivership or possession proceedings to immediate execution against goods. The court recognised considerable latitude for commercial decisions about the timing and method of recovery.

However, the court must be able to understand what happened and when. Saying that a creditor pursued alternatives does not explain a lengthy period unless the evidence sufficiently connects those alternatives with that period.

5.3 The evidence must be assessed in its practical context

Reasonableness includes considering what information the applicant possesses, or can fairly be expected to possess. A sophisticated assignee with access to its own files and transferred records should ordinarily be able to identify relevant communications, dates and decisions without disproportionate difficulty.

A general affidavit statement that the deponent has reviewed books and records is proper, but it does not make unsupported assertions sufficient. Nor does the decision require every document to be exhibited or establish a universal rule excluding evidence derived from records. Its objection was to the absence of readily available particulars needed to assess the explanation.

6. Why Mars’ Explanation Failed

The court examined individual periods before assessing the overall delay. Some intervals were adequately explained, but substantial gaps remained.

6.1 Pre-assignment negotiations

The statement that there had been “many” settlement attempts could describe intensive activity immediately after judgment or sustained engagement throughout the following three years. Those scenarios have materially different explanatory force.

Mars did not identify when negotiations occurred, what records supported its account or whether the lender’s decision to defer execution was recorded or inferred. The burden remained on Mars even though another institution owned the judgment during that period.

6.2 Portfolio review and the pandemic

Assessing an acquired loan book could explain some delay, but “some period of time” did not identify how long the task took or when Mars considered recovery of this particular judgment.

Likewise, reference to the pandemic and regulatory expectations was too general. Mars did not adequately identify the guidance’s operative dates, terms or application to judgment debts. The court did not establish that pandemic-related considerations could never explain delay; it found that their relevance here had not been demonstrated.

6.3 Receivership

Appointing a receiver could reasonably explain deferring another recovery method. But the bare facts of appointment, failure to obtain possession and later discharge left essential questions unanswered. Mars could readily have provided a concise account of the receiver’s efforts and when their failure became apparent.

The court repeatedly accepted that a reasonable explanation might exist. Its conclusion was that a possible explanation is not a proved explanation, and the court could not supply missing evidence through speculation.

7. Without Prejudice Negotiations: Protection Does Not Prevent Proof of Their Occurrence

The defendants objected to reliance on without prejudice discussions. Holland J distinguished their protected substance from evidence that they occurred.

QRD Development Company No.3 DAC [2022] IEHC 498 and Hamilton v PRTB [2023] IEHC 539 explained the policy and consensual foundations of the privilege. Settlement discussions must permit candid exploration of disputes without concessions later being used against a party. Allen v Helsinn Birex [2023] IEHC 684 was also cited, but the court considered it added nothing requiring separate treatment.

The relevant qualification emerged from several authorities:

• Unilever v Procter & Gamble [2000] WLR 2436 recognised that negotiations may be evidenced to explain delay or apparent acquiescence. Their relevance can lie in the fact of communication rather than the truth of any admission.
• Walker v. Wilsher 23 Q.B.D. 335 supported distinguishing the existence and dates of correspondence from its contents. The discussion in the later authority acknowledged that a fair account may occasionally require more.
• QPQ v Schute [2025] IEHC 474 was cited as a recent application of the relevant authorities.
• Malik v Malik and others [2025] EWHC 2485 (Ch) illustrated the use of such evidence when explaining delay in an application for extensions of procedural time limits.
• Ryan v. Connolly [2001] 1 IR 627 recognised that without prejudice correspondence could be considered to explain a course of conduct, rather than to bind a party to negotiating admissions. Its particular context concerned an alleged estoppel against reliance on a limitation defence.
• Bradford & Bingley plc v Rashid [2006] UKHL 37 appeared as supplementary authority in the privilege discussion, without supplying a separately analysed basis for the present result.

The practical conclusion was that Mars could have supplied dates and a neutral account of negotiations without ordinarily revealing offers, concessions or the reasonableness of either side’s negotiating position. Privilege was therefore not an adequate explanation for its evidential omissions.

The court expressly left open whether the operation of the privilege differs after judgment, when the debt itself is indisputable.

8. Other Arguments and Matters Left Undecided

8.1 Multiple remedies and borrower protections

A creditor may pursue different recovery routes together or successively. Receivership and possession proceedings were not inherently inconsistent with execution of the money judgment, nor did they imply its abandonment.

The defendants’ reliance on Start Mortgages v Gunn [2011] IEHC 275 was misplaced. That case concerned mortgage possession, not enforcement of a money judgment. It did not make compliance with the Code of Conduct on Mortgage Arrears a condition precedent to the latter.

This conclusion should not be read as removing protections applicable to possession proceedings. The court distinguished the remedies rather than deciding that the mortgage-enforcement framework could generally be disregarded.

8.2 Interest and prejudice

Following Bula Ltd (in receivership) v Tara Mines [2008] IEHC 437, continuing interest was not itself prejudice weighing against execution: payment of the judgment debt would stop its accrual.

However, the court did not determine the correct current balance or interest rate. It noted the original waiver of further interest and the possible relevance of judgment-debt rates or subsequent agreements, but left those matters for any appropriate enforcement dispute. The decision therefore does not approve Mars’ calculation of the amount due.

8.3 Stamp duty

LSREF III Stone Investments Limited v Morrissey [2015] IEHC 603 was invoked against the challenge to an allegedly unstamped transfer deed. Holland J questioned how its discussion of former practice reconciled with the statutory inadmissibility provision in section 127(4) of the Stamp Duties Consolidation Act 1999.

Mars ultimately relied on section 100 of the Finance Act 2007 as rendering the transfer non-stampable, and the defendants did not press the objection. The judgment consequently establishes no definitive resolution of that statutory question.

8.4 Transfer documentation

The challenge based on excessive redaction failed because it was not substantiated. The particular argument discussed in Mars Capital Finance DAC v Temple [2023] IEHC 94, concerning the relationship between a deed’s operative provisions and its schedule, was not treated as having been advanced here.

Promontoria v Lynn [2022] IEHC 99 supplied the reference point for notice under section 28(6) of the Supreme Court of Judicature Act (Ireland) 1877. The effectiveness of the transfer notices was not disputed, so that issue did not determine the outcome.

9. Likely Impact

For judgment creditors and loan purchasers

The judgment encourages creditors to prepare a concise, dated explanation supported by identifiable records. A prudent application will address:

• the period before assignment as well as the purchaser’s own period of ownership;
• when negotiations occurred and how they affected enforcement decisions;
• the duration and relevance of portfolio assessment;
• the actual application of regulatory guidance;
• the progress and outcome of alternative recovery measures.

It also reinforces the drafting value of expressly transferring existing judgments. Although the Irish authorities supported Mars’ title, clearer drafting would avoid dependence on a contested account of merger.

For judgment debtors

The decision confirms that evidential deficiencies can defeat an application even where the debt and the creditor’s title are established. Conversely, delay does not itself cancel the debt, ordinary interest accrual does not establish prejudice, and pursuit of mortgage remedies does not necessarily amount to abandonment of a money judgment.

For future courts

The useful analytical method is to identify explained and unexplained intervals, then assess the delay as a whole. This avoids treating either a single legitimate activity or an isolated gap as automatically decisive.

The judgment also provides a detailed invitation for appellate clarification of merger. Until such clarification, its operative approach remains adherence to the existing Irish authorities, not replacement of them by the English analysis.

10. Complex Concepts Simplified

Merger in judgment

The legal process by which a final judgment replaces the original cause of action. The difficult issue here was how that replacement affects a later assignment described as a transfer of the loan.

Chose in action

An intangible legal right enforceable through proceedings, such as a debt.

Substitution

Replacing a party in proceedings because the relevant legal interest has passed to another person or company. It does not, by itself, grant every permission needed for enforcement.

Leave to execute

The court’s permission to use execution procedures where the rules require prior approval, including after six years.

Fieri facias

A writ authorising recovery against a judgment debtor’s goods.

Without prejudice privilege

Protection for genuine settlement discussions. It does not ordinarily prevent proof that negotiations occurred at particular times when that fact explains delay.

Ratio decidendi

The legal reasoning necessary to a decision and capable of binding later courts. Judicial criticism or suggestions for reform do not automatically form part of that binding rule.

11. Conclusion

The central lesson is that the threshold for explaining delayed execution is low, but it is not empty. Creditors need not justify every commercial decision or demonstrate exceptional circumstances. They must nevertheless provide enough specific evidence for the court to understand the relevant delay.

Mars established ownership of the judgment but not entitlement to execute it on the evidence presented. The decision preserves existing Irish assignment law while sharpening the practical evidential requirements governing late execution and identifying merger as an issue deserving fuller appellate examination.
