Consent-to-judgment settlement clauses: summary judgment refused where implementation disputes (VAT allocation) raise a bona fide defence

1) Introduction

In Kavanagh and Anor v O'Neill and Anor (Approved) [2026] IEHC 590, the High Court (Bolger J) refused the first defendant’s application for summary judgment for €2,200,000 against the first plaintiff. The application was grounded on a settlement agreement (January 2023), later revised by agreement in July 2023, containing a default/consent-to-judgment clause (clause 2.9).

The dispute arose in the context of a compromised property transaction concerning Winestay House (the “property”), where the settlement contemplated the second plaintiff acquiring the property upon payment of agreed sums. The parties’ revised terms required exchange of a signed contract for sale that would include the “finalised VAT position”. A key issue then emerged: who bore liability for VAT on the sale, and whether the receiver’s inserted VAT clause created additional exposure beyond the settlement’s stated monetary total.

The first defendant argued that payment defaults automatically triggered clause 2.9 and that there was “no room for debate”. The first plaintiff contended that the payment obligation was not freestanding: it was consideration for receiving the property, and completion failed due to a genuine contractual dispute over VAT allocation—making summary judgment inappropriate.

2) Summary of the Judgment

  • Summary judgment refused. The Court held the first plaintiff had established a bona fide defence sufficient to obtain leave to defend at plenary hearing.
  • The existence of clause 2.9 (consent to judgment on default) did not defeat an arguable defence where the Court may need to determine why payments were not made and which party was at fault in implementing the revised settlement.
  • Arguments based on clean hands and estoppel by convention did not justify summary disposal, as they raised (or were bound up with) mixed questions of law and fact.
  • The Court rejected an attempt to obtain a partial judgment (sum claimed less alleged maximum VAT exposure), holding the defence—on the plaintiff’s case—went to the entirety of the amount sought.
  • Costs: indicative view that costs of the motion should be treated as costs in the cause (to be determined by the trial judge).

3) Analysis

3.1 Precedents Cited

Aer Rianta v Ryanair Ltd [2001] 4 IR 607

Bolger J applied the orthodox Irish test for resisting summary judgment: the respondent must show a fair or reasonable probability of having a real or bona fide defence, and the resisting party’s evidence is taken “at its highest” for the purpose of the application. This framing was central to the outcome: the Court did not decide the VAT construction dispute, but assessed whether it was sufficiently real and fact-sensitive to require a plenary trial.

The “Harris Grange principles” (McKechnie J)

The Court highlighted particular principles, notably:

  • (v) Where material factual issues affect success or failure, resolution is unsuitable for summary procedure.
  • (ix) Leave to defend should be granted unless it is very clear there is no defence.
  • (xii) The overriding factor is achieving a just result, mindful of the constitutional right of access to justice.

These principles operated as a caution against allowing a consent-to-judgment clause to become a shortcut to judgment where the alleged “default” may itself depend on contested questions of contractual implementation.

3.2 Legal Reasoning

(a) Clause 2.9 did not eliminate the need to examine the alleged “default”

Although clause 2.9 provided for consent to judgment upon default, Bolger J held it may still be necessary at trial to examine why payment was not made and who was at fault in implementing the revised settlement. On the first plaintiff’s case, the payment obligation was not independent of the vendor-side obligation to convey the property on agreed terms. That linkage made it arguable that non-payment might not constitute a simple, unilateral default triggering immediate judgment.

(b) VAT allocation was an arguable construction dispute embedded in the revised settlement

The Court treated the VAT dispute as capable of being a genuine issue for trial. Key features supporting an arguable defence included:

  • The revised settlement referred to a contract for sale in appended form, where the VAT provision had been “VAT - [TBC]” at the time of the original settlement documentation.
  • The revised terms specified a “total sum of €2,400,000” and (as argued) did not expressly add purchaser VAT liability, contrasted with an express “plus VAT” reference in respect of conveyancing costs.
  • The receiver delivered a signed contract containing a VAT clause said to be “standard” for receivership sales, but the plaintiffs disputed that it reflected the agreed position and refused to accept further “financial exposure”.

On a summary judgment application, these points were sufficient to show a credible, bona fide defence that could not be resolved without full evidence, including discovery and cross-examination.

(c) Prior affidavit statements could not dictate the interpretation of the later revised agreement

The first defendant relied on the first plaintiff’s earlier affidavit (May 2023) regarding VAT being a vendor/tax-specialist matter. Bolger J held that such material could not, of itself, inform the correct interpretation of the later agreement, particularly where the revised settlement attached documentation in which VAT had been left “TBC”. This reasoning reinforces a conventional contractual approach: the meaning and effect of the final revised bargain cannot be conclusively determined on the basis of a party’s earlier unilateral view, at least not on a summary basis.

(d) Estoppel by convention and “clean hands” were unsuitable for conclusive summary determination

The Court rejected the notion that alleged unclean hands could defeat the defence for the purpose of a summary judgment application, noting that the maxim (typically relevant to equitable relief) does not straightforwardly apply to a defendant resisting summary judgment at interlocutory stage.

As to estoppel by convention, the Court treated it as raising mixed questions of fact and law, not fit for conclusive resolution on affidavit alone in this procedural posture.

(e) No partial judgment where the defence goes to the whole claim

The first defendant sought, in the alternative, judgment for an amount net of a purported maximum VAT exposure. Bolger J rejected this: on the first plaintiff’s case, VAT was not part of what was agreed to be paid at all, and the alleged default mechanism could not be partially enforced without first resolving the foundational contractual dispute.

3.3 Impact

Practical limits on enforcing “consent to judgment” default clauses by summary motion

The decision signals that a settlement clause providing for consent to judgment on default will not necessarily yield summary judgment where the alleged default is intertwined with disputed performance or contested construction of the settlement’s operative exchange (here, payment in consideration of conveyance and VAT allocation). Parties seeking to draft robust default mechanisms should anticipate that summary enforcement may fail if the counterparty can plausibly link non-payment to unresolved obligations or ambiguities in the implementation documentation (such as a contract for sale required to “finalise” VAT).

Receivership sale documentation and “standard” VAT clauses

The judgment suggests that “standard” receivership clauses (including VAT provisions) may still be litigated where the parties’ settlement bargain arguably fixed a total price without additional VAT exposure, and where the appended contract documentation left VAT “TBC”. Disputes over whether such clauses are “material terms” may require plenary determination.

Procedural discipline: preserving plenary trial for mixed fact/law disputes

The case is a reminder that summary judgment is not a mechanism to decide contested contractual narratives where the outcome depends on context, conduct, and allocation of responsibility for non-completion. It underscores the High Court’s continued adherence to a low threshold for leave to defend where factual disputes are material.

4) Complex Concepts Simplified

  • Summary judgment: a fast-track procedure allowing judgment without a full trial where it is clear there is no real defence.
  • Bona fide defence: a genuine, credible defence that is arguable and could succeed at trial; it need not be proven on the motion.
  • Evidence “taken at its highest”: on the motion, the court assumes the resisting party’s evidence is true unless plainly implausible.
  • Specific performance: an order requiring performance of a contract (often used for property transactions), rather than damages.
  • Lis pendens: notice registered against property indicating litigation affecting the property is ongoing, warning third parties.
  • Estoppel by convention: where parties proceed on a shared assumption and one is prevented from later denying it; often fact-sensitive.
  • Clean hands: an equitable principle that can bar equitable relief to a party guilty of improper conduct; not automatically decisive when merely defending a claim at interlocutory stage.

5) Conclusion

[2026] IEHC 590 establishes, in practical procedural terms, that even a clear-looking consent-to-judgment clause in a settlement agreement will not necessarily support summary judgment where the respondent can show a bona fide, fact-sensitive defence about implementation of the settlement bargain—here, whether VAT liability formed part of the agreed consideration and whether the vendor-side delivery of the contract for sale complied with the revised terms.

The decision reinforces the low threshold for leave to defend under Aer Rianta v Ryanair Ltd [2001] 4 IR 607 and the “Harris Grange principles”, preserving plenary hearing for disputes turning on contractual context, responsibility for non-completion, and mixed questions of law and fact.
