On 28 October 2025, the Nordic–Baltic Chapter of the Club Español e Iberoamericano del Arbitraje (CEIA) hosted a webinar on “Early Determination in International Arbitration.” The session brought together legal professionals and institutional representatives to explore how the summary dismissal of claims or defences that are clearly unsustainable is reshaping modern arbitral practice.
This post reflects and expands on that discussion.
Early determination seeks to reconcile two perennial objectives: efficiency and fairness. It allows arbitral tribunals to dispose of plainly hopeless claims or defences swiftly, reducing cost and delay while maintaining procedural integrity. Once exceptional, this procedural tool is now embedded in several rule sets and even national statutes.
Institutional and legislative momentum
Arbitral institutions worldwide now empower tribunals to dispose of claims or defences that are manifestly unmeritorious or clearly unsustainable.
The ICSID Rules (Rule 41(5)) first introduced an expedited procedure for the early dismissal of unmeritorious claims in Rule 41(5) of the 2006 Rules, a power retained in the 2022 revision. The HKIAC Arbitration Rules have contained a similar mechanism since 2018 (Article 43) and preserve it under the same article. Similarly, the SIAC Arbitration Rules have permitted early dismissal since Rule 29 of the 2016 Rules and maintain that mechanism under Rule 47 of the 2025 Rules. The SCC Arbitration Rules introduced a summary procedure in Article 40 of the 2017 Rules, retained (with clarifying refinements) as Article 39 in the 2023 Rules.
Other recent examples include CRCICA 2024 Arbitration Rules (Article 52), arbitrateAD 2024 Rules (Article 45), CIETAC 2024 Arbitration Rules (Article 50), SCCA 2023 Arbitration Rules (Article 26), the AAA-ICDR 2021 Arbitration Rules (Article 23), the ACICA 2021 Arbitration Rules (Article 25.7), and the LCIA 2020 Arbitration Rules (Article 22.1(viii)).
Two new rule sets have joined this landscape: the KCAB International Arbitration Rules 2026 (Article 36) and the AIAC 2026 Arbitration Rules (Rule 9), both introducing express summary-determination procedures.
The ICC Rules are also under review, with a “motion to dismiss” mechanism reportedly under consideration.
By contrast, some institutions rely on general case-management powers rather than an express rule. The DIAC Arbitration Rules 2022 Rules and the Swiss Rules 2021 remain efficiency-oriented but stop short of codifying early dismissal, while the DIA 2021 Rules take a different route, appointing interim arbitrators to resolve procedural or evidentiary matters before a tribunal is constituted.
The procedural innovation has also migrated from institutional rules to legislation. The English Arbitration Act 1996 (as amended in 2025) now empowers tribunals, on a party’s application, to summarily determine any claim, defence or issue that has “no real prospect of success” (Section 39A). The provision does not prescribe when such an application may be made; time is left to the tribunal’s discretion, provided procedural fairness is maintained. Singapore is expected to follow with proposed amendments to the International Arbitration Act (IAA) introducing an equivalent power.
Practical considerations
Codification answers whether an arbitral tribunal can act, but not how it should. Four main considerations tend to dominate: threshold, timing, scope, and safeguards – all anchored in reliance on the applicable law.
A finding that a claim or defence is manifestly or clearlyunmeritorious sets a high bar; mere weakness will not suffice.Applications may arise before or alongside jurisdictional issues, but tribunals should confine them to discrete questions of law or clearly unsustainable factual claims. Whatever the timing, speed must never come at the expense of fairness; both sides must be heard and the decision reasoned.
The choice of the governing law can also influence whether early determination is appropriate. While the lex arbitri provides the procedural framework, the governing law of the contract and the law of the arbitration agreement may each affect how the tribunal assesses a claim’s viability. For example, a governing law might determine whether a claim is legally tenable, while the law of the arbitration agreement could affect jurisdiction or admissibility. Tribunals must therefore ensure any early determination aligns with the broader legal architecture of the arbitration.
Early determination may also serve as a mechanism for resolving preliminary legal issues from which significant aspects of the dispute can be narrowed or resolved entirely. This approach may be particularly appropriate where the factual and legal matrices of the dispute, as well as its overall complexion, warrant an early disposition of certain claims or defences.
In assessing suitability, tribunals may ask:
- Do the underlying questions of fact or law lend themselves to early resolution?
- Are the issues sufficiently straightforward to be summarily disposed of?
Early determinations can be particularly effective in disputes of modest quantum, or in cases where facts are largely uncontested and lack complex or novel points of law. Conversely, high-stakes, multi-party arbitrations, or those reliant on robust factual evidence and contested narratives, are generally ill-suited to summary determination.
Beyond these fundamentals, a growing body of practice offer further guidance. Procedurally, many tribunals adopt a two-stage approach: an initial ‘gateway’ application demonstrating suitability, followed by a short, focused merits phase. Most applications are determined on written submissions, though a brief hearing may be held if clarification is required. Early determination may be invoked at almost any stage, including post-disclosure, where it demonstrably promotes efficiency.
Fairness and proportionality remain central to the nature of these applications. Tribunals should record how procedural equality was maintained, note that both parties were heard, and explain why the approach adopted was proportionate. Institutions such as the CPR recommend addressing early determination at the first procedural conference to embed its use, reduce ‘due process paranoia’, and identify issues potentially ripe for summary disposal.
Strategic and cost considerations are equally important. To deter tactical or weak applications, tribunals may allocate costs against unsuccessful applicants or require acknowledgment of that risk at the outset. Conversely, a well-targeted application can demonstrate procedural discipline and credibility, particularly when confined to issues capable of narrowing the dispute. As the CPR Guidelines on Early Disposition of Issues in Arbitration note, the mechanism should be reserved for issues that are dispositive, undisputed in fact, and ripe for decision.
Time and flexibility are also key. For example, the reformed English Arbitration Act 1996 confirms that summary disposal may be used at any appropriate stage, even after evidence or disclosure, where efficiency and fairness so require. The process is typically party-driven, and tribunals must ensure both sides receive notice and a fair opportunity to respond.
Finally, institutions and practitioners share responsibility for building confidence. Transparency (through publication of anonymised decisions, model orders, or procedural guidelines) would help normalise early determination and foster consistency.
Handled appropriately, early determinations can avoid unnecessary and costly procedural steps – for example, disclosure or witness/expert evidence, while significantly narrowing the scope of issues to be tried. Mishandled, they can undermine enforceability and invite due-process challenges.
A developing orthodoxy
The legislative appetite for early determination is clear. England has legislated, Singapore is expected to follow, and arbitral institutions from Kuala Lumpur to New York, Cairo, and Sydney have done likewise. Together, they mark a growing orthodoxy that arbitral tribunals may act swiftly, provided they act fairly.
Early determination is a disciplined use of procedural authority to keep arbitration efficient, credible, and aligned with modern commercial expectations. Nonetheless, its success will depend less on how often it is used than on how well it is applied.
