Finality of Perfected High Court Orders: Limits of the Slip Rule, Inherent Reopening, and Litigant-in-Person Cost Measurement

Case: Nowak v Intesa Sanpaolo Vita S.P.A (Approved) [2026] IEHC 295
Court: High Court of Ireland
Judge: Simons J.
Date: 13 May 2026

1. Introduction

This decision concerns an application to amend perfected High Court orders following an earlier judgment refusing to dismiss two consolidated wrongful-dismissal plenary actions for inordinate and inexcusable delay. The plaintiff (a litigant in person) sought further amendments to orders that had already been corrected once under the “slip rule”.

The immediate dispute arose from the plaintiff’s attempt to maximise recoverable litigation outlay and to revive (or re-enter) motions for judgment in default of defence—despite the defendant having delivered a defence pursuant to case-management directions made in the earlier “delay” ruling.

Key issues

  • The scope of the “slip rule” in Order 28, rule 11 of the Rules of the Superior Courts (clerical mistakes / accidental slips or omissions).
  • Whether (and in what circumstances) the High Court can revisit or rewrite a perfected order otherwise than by appeal.
  • Whether the plaintiff could delete references to default motions to attempt to invalidate a defence already delivered.
  • How a litigant in person’s recoverable outlay/expenses should be measured, and whether Part 10 adjudication under the Legal Services Regulation Act 2015 is available/appropriate.
What is “new” (in practical precedent terms):
  • Clear reaffirmation that Order 28, rule 11 cannot be used to rewrite perfected orders to pursue a changed litigation strategy.
  • Strong emphasis that parties who were invited to contest a proposed form of order—but did not—face serious finality, acquiescence, and promptness barriers to later reopening.
  • Confirmation that case-management directions following refusal of a delay strike-out can render Order 27 default motions “spent/moot”, with costs dealt with separately.
  • Reassertion that litigants in person can recover outlay (not personal time/labour), and that Part 10 adjudication is a standard route unless properly challenged via the statutory reference mechanism.

2. Summary of the Judgment

The Court refused the plaintiff’s application to amend the perfected orders and refused the attempt to re-enter the two motions for judgment in default of defence.

  • The amendments sought were not clerical corrections: they aimed to remove substantive elements that implemented the intent of the earlier judgment.
  • Even assuming an exceptional inherent jurisdiction to revisit perfected High Court orders might exist (despite an automatic appeal right), the plaintiff did not satisfy the strict conditions (no fundamental denial of justice; acquiescence; lack of promptness; extensive delay).
  • The default motions were, in substance, rendered moot by directions deeming the statement of claim delivered and requiring delivery of a defence, which was in fact delivered on time.
  • As to measurement of outlay/expenses, the plaintiff’s late attempt to switch from Part 10 adjudication to court measurement was rejected, particularly given her participation in adjudication and the availability of a statutory reference route if a jurisdictional issue arises.
  • Costs: no order as to costs on the amendment applications; each party bore its own costs due to earlier confusion in drawing up orders.

3. Analysis

3.1 Precedents Cited (and their influence)

(a) Delay and case management: from Primor to Kirwan

  • Primor plc v. Stokes Kennedy Crowley [1996] 2 IR 459: The earlier (principal) refusal to strike out for delay was decided under Primor, which framed the traditional inordinate/inexcusable delay analysis and “balance of justice” inquiry.
  • Kirwan v. Connors [2025] IESC 21: Although the principal judgment predated Kirwan, Simons J. relied on Kirwan in this later decision for the proposition (per O’Donnell C.J.) that where a court refuses to dismiss for delay, it has inherent power to case manage to ensure the case proceeds to trial within a reasonable time. This underpinned the legality of directions that effectively neutralised the plaintiff’s default motions by compelling delivery of a defence.

(b) Finality and reopening perfected orders

  • In the matter of Greendale Developments Ltd (No. 3) [2000] 2 IR 514 and Student Transport Scheme Ltd v. Minister for Education and Skills [2021] IESC 35: These authorities articulate the exceptional appellate-court jurisdiction to revisit perfected orders where finality must yield to a profound constitutional unfairness amounting to nullity. Simons J. treated this as illustrating the high bar for reopening and questioned whether a comparable jurisdiction even exists at High Court level where an automatic appeal lies.
  • G. v. Director of Public Prosecutions [2023] IEHC 386: Cited for the proposition that where an automatic appeal exists, it generally provides an effective remedy—making any supposed “reopening” jurisdiction at first instance even less likely.
  • Nash v. Director of Public Prosecutions [2017] IESC 51: Used to explain the rationale for tight limits: not because judges do not err, but because the legal system channels correction of substantive error into timely appeal to protect finality and litigants’ legitimate expectations.

(c) Default judgment in plenary proceedings: Order 27 “interests of justice”

  • Nowak v. Courts Service of Ireland [2026] IECA 81: Central to the court’s “even if you could, you would fail” reasoning. The Court of Appeal’s discussion of Order 27 emphasises a fact-sensitive “interests of justice” inquiry (broader than “special circumstances”), including: delay extent and explanation, prejudice/urgency, party engagement, and whether a defence is already finalised and provided—making an “unless order” potentially academic.

(d) Litigant in person costs: outlay yes, personal time no

  • Dawson v. Irish Brokers Association [2002] IESC 36, [2002] 2 I.L.R.M. 210: Reaffirmed as authority that a litigant in person can recover allowable outlay and out-of-pocket expenses, though not professional fees.
  • Skoczylas v. Minister for Finance [2024] IECA 201: Relied on for the modern statement of the limit: recoverable items may include court fees, stamp duty, vouched expert/professional outlays, necessary travel/accommodation (vouched), and reasonable copying/postage—but exclude any sum for the litigant’s own time, expertise, or labour.

3.2 Legal Reasoning

(a) The “slip rule” is narrow: correction, not revision

Order 28, rule 11 permits correction of clerical mistakes or accidental slips/omissions. The plaintiff’s proposed edits were not corrections of recording errors. They were an attempt to delete substantive provisions that:

  • recorded the court’s intent to make case-management directions, and
  • treated the default motions as moot while awarding their costs.

Simons J. treated this as a paradigmatic misuse of the slip rule: the plaintiff sought to rewrite the order to obtain a different litigation outcome.

(b) Finality, acquiescence, and promptness defeat “inherent jurisdiction” arguments

The judgment assumes (without deciding) that there might be “exceptional circumstances” where the High Court could revisit a perfected order despite an appeal right. However, it held that the plaintiff’s case failed on core prerequisites:

  • No fundamental denial of justice through no fault of the applicant: the plaintiff had been expressly invited to make submissions on the proposed form of order and did not do so.
  • Acquiescence / approbation and reprobation: the plaintiff had actively relied on the existing costs framework—indeed sought and obtained a prior amendment inserting costs language—and then attempted to delete that same language when it became strategically inconvenient.
  • Failure to move promptly: the attempt to re-enter default motions came almost two years after the principal judgment, against a background of earlier inordinate and inexcusable delay.

(c) Case management can neutralise default motions—and that may be essential to refusing dismissal for delay

The earlier refusal to dismiss for delay was coupled with directions designed to ready the case for trial by completing pleadings (deeming the statement of claim delivered and directing delivery of a defence). This:

  • made the default motions “spent” in substance (the mischief—no defence—was cured), and
  • left only the question of costs of those motions, which the court addressed.

The judgment also makes a practical point: without the ability to impose such directions, the defendant’s delay strike-out might have succeeded—so the directions were, in effect, a judicial mechanism to mitigate delay harms while preserving a trial on the merits.

(d) “Even if permitted, it would fail”: default judgment would not be granted on these facts

Applying the guidance in Nowak v. Courts Service of Ireland [2026] IECA 81, Simons J. held that any judge hearing the default motions now would inevitably extend time for delivery of the defence in the interests of justice, because:

  • the defendant reasonably awaited determination of the dismissal-for-delay motions before incurring the expense of a defence;
  • the plaintiff’s own delay (years before a statement of claim) dwarfed any alleged default period;
  • once required, the defence was delivered on the specified date; and
  • the plaintiff’s two-year delay in re-entering the motions would make it inequitable to deny a defence on the merits.

(e) Measurement of a litigant-in-person’s outlay: standard order, statutory routes, and procedural discipline

The plaintiff sought to delete references to Part 10 adjudication and have the High Court measure outlay instead. The Court refused, emphasising:

  • It is long established that a litigant in person can recover outlay/out-of-pocket expenses; nothing in the Legal Services Regulation Act 2015 shows an intention to oust that.
  • Section 168(1)(a) (“costs of or incidental to the proceedings”) mirrors historic costs language and has been interpreted to allow such outlay recovery.
  • If the Legal Costs Adjudicator raises a jurisdictional concern, the appropriate mechanism is a reference to the High Court under section 159, not rewriting perfected orders.
  • Where a party has already participated substantially in adjudication (including a first instance determination and a reconsideration request under section 160), it is generally too late to “switch tracks” and ask the High Court to measure costs in gross under Order 99.

3.3 Impact

  • Procedural finality is reinforced: parties should treat the “form of order” invitation seriously; silence can foreclose later attempts to recast orders as “mistakes”.
  • Slip rule boundaries clarified in a costs-and-case-management context: the judgment is a practical reminder that Order 28, rule 11 is not a substitute for appeal and not a tool to reverse case-management choices.
  • Default motions are not tactical weapons once pleadings are regularised: where a defence is delivered (especially under court direction), revival of default motions will likely be treated as academic or inequitable.
  • Litigants in person: the decision reiterates entitlement to recover outlay (not personal time) and signals that adjudication pathways and statutory references—rather than ad hoc order rewrites—are the proper route for jurisdictional disputes about measurement.

4. Complex Concepts Simplified

Perfected order

An order is “perfected” once it has been formally drawn up, checked, and entered. After perfection, the legal system places high value on finality: substantive change is usually only through appeal.

Order 28, rule 11 (“slip rule”)

A mechanism to correct accidental recording errors (typos, misstatements, omissions) so the order matches what the court actually decided. It is not for changing the decision.

Inherent jurisdiction to reopen

Courts have limited inherent powers to prevent fundamental unfairness, but these are exceptional and tightly controlled—especially after perfection and where an appeal is available.

Judgment in default of defence (Order 27)

A procedure to deal with a defendant who has not delivered a defence in time. Courts often focus on whether, in the interests of justice, time should be extended rather than entering final judgment, particularly if a defence is available and denial would be disproportionate.

Costs vs outlay for litigants in person

A self-represented party generally cannot claim for their own time spent preparing and conducting the case. They can, however, typically recover necessary, vouched expenses (court fees, copying, travel, experts) if awarded “costs”.

5. Conclusion

Nowak v Intesa Sanpaolo Vita S.P.A [2026] IEHC 295 is a firm statement of procedural discipline: perfected orders are not to be reopened or rewritten via the slip rule to facilitate a changed strategy, particularly where the party had an express opportunity to contest the form of order, later relied on it, and delayed extensively. The judgment also underscores that post-delay-strike-out case management can legitimately regularise pleadings and render default motions moot, while costs for such motions may still be addressed. Finally, it reaffirms orthodox principles on litigant-in-person cost recovery: outlay is recoverable (vouched and necessary), personal time is not, and statutory mechanisms—not retrospective order surgery—are the proper means to resolve adjudication-jurisdiction concerns.
