The DIFC Court of Appeal dismissed the appellants' challenge to a first-instance decision granting relief from sanctions, confirming that a good explanation for non-compliance is an important factor under RDC 4.49 but is not a condition precedent to relief. The judgment also confirms that DIFC appellate courts apply robust deference to discretionary case-management decisions, intervening only where the judge erred in principle, ignored a material consideration, or reached a conclusion plainly outside the range reasonably open to him. The case arose from late service of a witness statement in expedited commercial proceedings. The respondent's justification — that a witness had been deterred from testifying by threats and alleged assaults — was contested. The first-instance judge declined to make final findings on those allegations but identified prima facie evidential support sufficient to weigh in favour of relief, alongside his assessment that the excluded evidence was central to the trial issues. The Court of Appeal held this approach was legally correct and that the overall evaluative exercise under RDC 4.49 had been conducted without error of principle.
Decision
The Court of Appeal dismissed the appeal and ordered the appellants to pay the respondent's costs, summarily assessed at USD 160,000. The court held that the first-instance judge correctly applied the evaluative framework under RDC 4.49; that a good explanation for non-compliance is an important but not determinative factor, the absence of which does not bar relief where the overall circumstances justify it; and that the prima facie evidential support standard is the legally correct measure when contested facts underlying an explanation also fall to be determined at trial. No error of principle, extraneous consideration, ignored material factor, or plainly wrong conclusion was established. The high threshold for appellate intervention in discretionary case-management decisions was not met.
Facts
The underlying dispute is a substantial commercial matter proceeding before the DIFC Court of First Instance on an expedited timetable. By a case management order dated 5 December 2025, the respondent (Igor Chuprin) was required to serve witness statements by 19 December 2025, with any supplementary statements due by 19 January 2026. He failed to serve a witness statement from Ms Alena Kurulenko within either deadline. The omission only came to a head on 17 March 2026, during the trial itself, when the respondent applied for three forms of relief: relief from sanctions for the breach, admission of Ms Kurulenko's out-of-time witness statement, and permission for her to give oral evidence remotely. The respondent's explanation was that Ms Kurulenko had been deterred from coming forward as a witness by threats, intimidation and alleged physical assaults directed at her and at members of her family, which had prevented earlier service of her statement. The allegations were contested. H.E. Justice Andrew Moran granted the application by Order dated 10 April 2026, making consequential procedural directions to accommodate the late evidence. He expressly acknowledged that the failure to comply with the court order was serious and significant, that the application had been made very late, and that granting relief would cause the appellants delay, additional costs and procedural disadvantage. He did not, however, make any final findings of fact on the disputed allegations of threats and intimidation. He found instead that there was prima facie evidential support for the respondent's account — meaning the explanation was supported by material going beyond mere assertion and, if established, would constitute a good explanation for the failure to comply — and that Ms Kurulenko's evidence was central to the issues at trial, such that refusing relief risked determining the proceedings without potentially critical evidence. After weighing the competing prejudice to the appellants against the interests of justice, Justice Moran concluded that relief should be granted. The appellants obtained permission to appeal on 15 April 2026 and pursued their challenge before the Court of Appeal. They contended that the judge had erred in principle and that his decision fell outside the range of decisions open to him. Mr Michael Walsh KC, instructed by Trowers and Hamlins LLP, appeared for the appellants; Mr Alexander Cook KC, instructed by Bracewell LLP, appeared for the respondent. The appeal was heard on 21 May 2026 and dismissed from the bench, with written reasons delivered on 8 June 2026.
Issues before the court
- Whether a good explanation for failure to comply with a court order is a condition precedent to the grant of relief from sanctions under RDC 4.49, or merely one factor in an overall evaluative exercise?
- Whether a first-instance judge, faced with contested interlocutory evidence, may proceed on the basis of prima facie evidential support for an explanation without making final findings of fact, and whether that approach is legally correct?
- Whether the first-instance judge erred in principle, took into account irrelevant matters, ignored material considerations, or reached a conclusion outside the range reasonably open to him, so as to warrant appellate intervention?
- What standard of appellate restraint applies to discretionary case-management decisions in the DIFC courts, particularly decisions on relief from sanctions?
The court's reasoning
The Court of Appeal began by setting out the structure of RDC 4.49, which requires the court to consider all the circumstances of the case, including: the interests of the administration of justice; whether the application was made promptly; whether the failure was intentional; whether there is a good explanation for it; the extent of the party's compliance with other requirements; whether the failure was caused by the party or its legal representatives; whether the trial date can still be met; and the respective effects of the failure and of granting relief on each party. No single factor is decisive; each carries such weight as the particular circumstances warrant. The court confirmed that RDC 4.49 operates materially identically to CPR r 3.9, making the structured framework in Denton v TH White Ltd [2014] EWCA Civ 906 directly applicable, as already endorsed in DIFC proceedings by Mad Atelier International BV v Axel Manes [2022] DIFC CFI 030. The court was careful to add, however, that the three Denton stages are not mechanical checkpoints. They are components of a single overall evaluative exercise, and the entire task is one of assessment rather than sequential gatekeeping. On the specific question of whether a good explanation is a prerequisite to relief, the court was unequivocal. Its absence may weigh heavily against the applicant, but it does not foreclose relief where the totality of circumstances so justifies. The court drew support from two recent English decisions that do the specific doctrinal work of illustrating this point in practice: Tiernan-Spratt v City of Wolverhampton Council [2023] EWHC 811 (KB) (at paragraphs 50–51) and Baroness Lawrence v Associated Newspapers Ltd [2026] EWHC 556 (KB) (at paragraph 39). Both cases resulted in relief being granted notwithstanding that no good reason for the default had been established, because the overall circumstances demanded it. These authorities confirmed, in the court's view, that the good explanation inquiry is calibrated within a broader balancing exercise, not absolute. On the prima facie evidential support standard, the court endorsed the judge's decision to decline making final findings on the contested allegations of threats and intimidation at the interlocutory stage. The established principle — applicable equally in DIFC and common law interlocutory practice — is that courts must not convert case-management applications into mini-trials, particularly where the evidential record is incomplete or the issues are not apt for definitive determination at that stage, and especially where the matters in dispute overlap with issues to be resolved at trial. Where evidence is genuinely contested, the appropriate inquiry is whether the explanation is supported by material going beyond bare assertion. A conclusion that prima facie evidential support exists is explicitly provisional in character: it does not treat the underlying facts as proved, nor does it equate an arguable explanation with an established one. It signals only that if the material were accepted it could constitute a good explanation, while leaving the underlying facts unresolved. The weight to be attached to such support remains part of the overall RDC 4.49 balancing exercise; it does not substitute for that exercise. The court also addressed the interests of the administration of justice as a free-standing consideration under RDC 4.49. Where refusal of relief would exclude relevant and potentially important evidence bearing on central issues at trial, that may weigh in favour of granting it. It is not decisive, and must be balanced against all other relevant circumstances including the importance of procedural compliance and the prejudice to the opposing party. Here, the judge had found that Ms Kurulenko's evidence was central to the case. Refusing relief would have risked determining the proceedings without hearing potentially critical evidence. That was a consideration he was entitled to weigh heavily, and the Court of Appeal found no basis for concluding he had misdirected himself in doing so. On appellate restraint, the court applied the House v The King (1936) 55 CLR 499 standard. Appellate intervention requires identification of one of the following: an error of principle; reliance on extraneous or irrelevant matters; failure to take into account a material consideration; a material error of fact; or a conclusion so unreasonable or plainly unjust that a proper exercise of discretion can be inferred to have miscarried. The threshold is deliberately high for case-management decisions, which involve a fact-sensitive evaluative exercise entrusted to the trial judge, who is best placed to assess the circumstances of the proceedings. Mere disagreement with the outcome does not suffice. The court found none of the enumerated errors. The judge had expressly acknowledged the seriousness of the breach, the lateness of the application, and the concrete prejudice to the appellants before concluding that the interests of justice in having central evidence available at trial outweighed those concerns. That conclusion was reasonably open to him, and the appeal was accordingly dismissed.
Applicable law
- RDC 4.49 — Rules of the Dubai International Financial Centre Courts: enumerates the factors governing the grant of relief from sanctions for failure to comply with a court order; requires consideration of all the circumstances of the case including the interests of the administration of justice, promptness of application, intentionality of the breach, existence of a good explanation, compliance with other requirements, cause of the failure, whether the trial date can still be met, and respective prejudice to each party
- RDC 4.50 — requires that an application for relief from sanctions be supported by evidence, but does not require the applicant to establish the facts relied on to a final standard or on the balance of probabilities
- CPR r 3.9 (England and Wales) — applied by analogy as the materially identical counterpart to RDC 4.49
- Denton v TH White Ltd [2014] EWCA Civ 906 — three-stage structured approach to relief from sanctions, adopted in DIFC proceedings per Mad Atelier International BV v Axel Manes [2022] DIFC CFI 030; the stages are not mechanical but form part of a single overall evaluative exercise
- Mad Atelier International BV v Axel Manes [2022] DIFC CFI 030 — DIFC authority confirming that the Denton framework applies under RDC 4.49
- House v The King (1936) 55 CLR 499 — appellate restraint standard for review of discretionary decisions; intervention requires error of principle, reliance on extraneous matters, failure to consider a material matter, material error of fact, or a plainly wrong conclusion outside the generous ambit of reasonable disagreement
- Tiernan-Spratt v City of Wolverhampton Council [2023] EWHC 811 (KB) (at [50]–[51]) — persuasive English authority that relief from sanctions may be granted notwithstanding the absence of a proved good reason for default where the overall circumstances so require
- Baroness Lawrence v Associated Newspapers Ltd [2026] EWHC 556 (KB) (at [39]) — persuasive English authority to the same effect, cited alongside Tiernan-Spratt as recent illustration of the Denton approach in practice
Practical implications
Parties seeking relief from sanctions in DIFC proceedings should not treat the absence of a fully provable explanation as fatal. The RDC 4.49 exercise is holistic, and a strong case on other factors — particularly the centrality of the excluded evidence to the trial issues and the interests of the administration of justice — can sustain a successful application even where the explanation for default is contested or unproved at the interlocutory stage. That said, this judgment is not a licence for careless non-compliance. The first-instance judge expressly found the breach serious and the application very late. Relief was granted only because the evidence was demonstrably central to trial issues and the explanation was supported by material going beyond bare assertion. Applicants must therefore ensure that any explanation advanced is corroborated by documentary or independent evidence rather than narrative assertion alone, and must apply as early as possible — promptness remains an enumerated RDC 4.49 factor and lateness was a factor weighed against the respondent here, even though it did not ultimately defeat the application. Where the explanation for default involves sensitive factual allegations — such as witness intimidation — parties should assemble all available supporting material before the application hearing. The court will not make final findings at the interlocutory stage, but it will assess whether the explanation is supported beyond mere assertion. Corroboration strengthens that assessment. For opposing parties, resisting relief on the sole ground that no good explanation exists will rarely succeed where the overall balance of justice points the other way. Tactical energy is better directed at demonstrating concrete, non-compensable prejudice and, crucially, challenging the claimed centrality of the late evidence to the trial issues. On the court's reasoning, evidence that is not genuinely central to contested issues would attract considerably less weight in the balancing exercise. On appeal, the threshold for overturning a relief-from-sanctions decision is demanding. A specific error of principle, an ignored material consideration, or a conclusion plainly outside the range open to the judge must be identified — disagreement with the outcome is not enough. Cost exposure on an unsuccessful appeal is substantial: USD 160,000 was summarily assessed on a one-day hearing, a figure that signals the DIFC Court of Appeal will not discount costs for commercially contested but procedurally straightforward grounds.
Precedent value: As a DIFC Court of Appeal decision, this judgment binds the DIFC Court of First Instance and all lower DIFC tribunals. It is authoritative on two discrete points. First, the absence of a good explanation for non-compliance is not a bar to relief from sanctions under RDC 4.49; it is a weighty factor within an overall evaluative exercise, not a condition precedent. Second, the prima facie evidential support standard is the legally correct interlocutory measure where contested facts underlying an explanation for default also fall to be determined at trial. The judgment also reaffirms the appellate restraint standard drawn from House v The King as the applicable threshold for review of discretionary case-management decisions in DIFC proceedings.
Action point
Parties to expedited DIFC proceedings who face late evidence applications from opposing parties should immediately assess whether the excluded evidence is genuinely central to the trial issues, since that factor carries significant weight in the RDC 4.49 balancing exercise and may be sufficient, combined with other circumstances, to secure relief even in the absence of a proved explanation for the default. Litigants considering an appeal against a grant of relief from sanctions should carefully identify whether a specific, reviewable error of principle exists before committing to a challenge — a failed appeal in this jurisdiction carries substantial costs consequences, as the USD 160,000 summary assessment in this case illustrates.
