When Can an Arbitration Be Terminated for "impossibility"? DRL V DRK Explained

The termination of arbitration in Singapore on grounds of “impossibility” has moved from doctrinal footnote to front-page concern following the Singapore High Court’s decision in DRL v DRK [2026] SGHC 32. In that landmark ruling, the Court upheld a SIAC tribunal’s decision to terminate proceedings after international sanctions made continuation of the arbitration practically impossible. The decision clarifies, for the first time at the SGHC level, exactly when Article 32(2)(c) of the UNCITRAL Model Law, as incorporated into Singapore’s Arbitration Act 2001, compels a tribunal to close the file. For general counsel, arbitration practitioners and commercial parties with SIAC-seated disputes, the judgment reshapes enforcement planning, risk assessment and arbitration clause drafting in material ways.

Executive Summary: The Short Answer for GCs

Before examining the legal framework in detail, here is what decision-makers need to know immediately about the termination of arbitration in Singapore after DRL v DRK.

Key takeaway: A tribunal must terminate arbitration proceedings when the continuation of those proceedings has become impossible, and the Singapore courts will defer to the tribunal’s factual assessment of impossibility, provided the tribunal applied the correct legal test and afforded procedural fairness.

What GCs must know now:

• The threshold is objective impossibility, not mere difficulty. The tribunal must find that no reasonable procedural adaptation could allow the arbitration to continue to a meaningful award.
• Sanctions were the trigger in DRL v DRK. International sanctions prevented the claimant from accessing evidence, instructing witnesses and receiving any monetary award, the tribunal concluded that the proceedings were rendered futile.
• The SGHC applied a deferential standard of review. The Court held that a tribunal’s determination of impossibility is a finding of mixed fact and law, attracting significant deference on judicial review.
• Prior interim awards or orders may survive termination. Termination of the main proceedings does not automatically void interim measures already granted, though enforcement challenges increase.
• Clause-drafting is now a priority. Parties negotiating arbitration agreements should consider impossibility carve-outs, continuance obligations and emergency preservation protocols, all discussed in the drafting section below.

If you are the claimant: Review whether the tribunal’s impossibility finding rested on correct legal grounds, and consider whether the factual predicates have changed (e.g., sanctions lifted). Explore an application to the SGHC to challenge the termination order or, if interim awards were issued, pursue enforcement immediately.

If you are the respondent: The termination may serve your interests, but anticipate challenge applications. Preserve evidence of the sanctions regime and the impossibility finding to defend the termination in any court proceedings.

Termination of Arbitration in Singapore: Legal Framework

Model Law, Arbitration Act 2001 and SIAC Rules 2025

Singapore’s international arbitration regime is anchored in the UNCITRAL Model Law on International Commercial Arbitration, given force of law through the International Arbitration Act (Cap. 143A). For domestic arbitrations, the Arbitration Act 2001 applies. Both statutes incorporate Article 32 of the Model Law, which sets out the circumstances in which arbitral proceedings are terminated.

Article 32(2) provides three grounds on which a tribunal shall issue an order terminating the proceedings:

• Article 32(2)(a): The claimant withdraws the claim (unless the respondent objects and the tribunal recognises a legitimate interest in obtaining a final award).
• Article 32(2)(b): The parties agree on the termination.
• Article 32(2)(c): The tribunal finds that the continuation of the proceedings has, for any other reason, become unnecessary or impossible.

Section 32 of the Arbitration Act 2001 mirrors this framework for domestic arbitrations seated in Singapore. Meanwhile, Section 49 of the same Act provides a limited right of appeal to the SGHC on a question of law arising out of an award, a provision that becomes relevant when parties seek to challenge a termination order, as discussed further below.

The SIAC Rules 2025, which apply to arbitrations commenced on or after 1 January 2025, contain corresponding provisions. Rule 32.3 requires a tribunal to terminate proceedings when it determines that their continuation has become unnecessary or impossible. Rule 53.2 addresses the finality of awards and orders, providing that a termination order constitutes a final procedural determination by the tribunal. These rules reinforce the tribunal’s gatekeeping duty: once impossibility is established, termination is mandatory, not discretionary.

Tribunal Versus Court Roles

A critical distinction lies in the allocation of decision-making power. The tribunal makes the primary determination on whether continuation is impossible. The court’s role is supervisory, it reviews the tribunal’s decision on application by a dissatisfied party, but it does not substitute its own factual assessment. This division was central to the reasoning in DRL v DRK, where the SGHC emphasised that it would not re-weigh the evidence underlying the tribunal’s impossibility finding. Industry observers expect this deferential posture to be followed consistently in subsequent SGHC and Singapore Court of Appeal decisions, reinforcing Singapore’s pro-arbitration reputation.

DRL v DRK [2026] SGHC 32: Case Summary and Annotated Analysis

The Facts

The dispute arose from a commercial contract between parties engaged in cross-border commodity trading. After arbitration was commenced under the SIAC Rules, a comprehensive international sanctions regime was imposed targeting one of the parties and its associated entities. The sanctions had cascading practical consequences: the claimant’s legal representatives were unable to receive instructions or transfer funds; key witnesses became unreachable; documentary evidence held in sanctioned jurisdictions could not be produced; and any monetary award in the claimant’s favour would have been unenforceable due to asset-freezing measures.

The Tribunal’s Decision to Terminate

The SIAC tribunal conducted a thorough procedural review, inviting submissions from both parties on whether the arbitration could continue. After considering the scope and duration of the sanctions, the availability of procedural workarounds (such as adjournment, bifurcation or appointment of a litigation trustee), and the prospects of meaningful relief, the tribunal concluded that the continuation of the proceedings had become impossible within the meaning of Article 32(2)(c) of the Model Law. It issued a termination order, ending the arbitration without a final award on the merits.

The SGHC Decision: Holdings and Reasoning

The claimant applied to the Singapore High Court to set aside the termination order. The SGHC, in a detailed judgment, dismissed the application and upheld the tribunal’s decision. The Court’s reasoning can be distilled into several key holdings.

First, on the legal test for impossibility: The Court confirmed that “impossible” under Article 32(2)(c) means that it is not practically feasible for the proceedings to continue to a meaningful conclusion. The test is objective: the tribunal must assess whether, taking into account all available procedural tools, the arbitration can still serve its purpose of resolving the dispute and producing an enforceable award. Mere difficulty, inconvenience or increased cost does not satisfy the threshold.

Second, on the standard of review: The SGHC held that the tribunal’s assessment of impossibility is a finding of mixed fact and law. The Court stated that it would accord significant deference to the tribunal’s factual findings, intervening only if the tribunal applied the wrong legal test, failed to consider relevant matters, or reached a conclusion that no reasonable tribunal could have reached. The Court observed that the tribunal had “carefully and methodically evaluated each procedural alternative” before concluding that none could remedy the impossibility.

Third, on the sanctions as a factual predicate: The Court agreed that the sanctions in question were not temporary inconveniences but structural impediments that removed the claimant’s practical ability to prosecute its claim and the respondent’s ability to receive a fair hearing. The tribunal’s finding that the sanctions rendered the proceedings “incapable of achieving any just resolution” was upheld as well within the range of reasonable conclusions.

Fourth, on procedural fairness: The SGHC noted that the tribunal had given both parties full opportunity to be heard on the impossibility question, had considered and rejected multiple procedural alternatives, and had provided detailed reasons for its termination order. There was no breach of natural justice.

Fifth, on the limits of the decision: The Court was careful to note that its ruling was confined to the specific factual matrix, a comprehensive sanctions regime with no foreseeable end date. The judgment does not establish a general licence for tribunals to terminate proceedings at the first sign of regulatory difficulty. Each case must be assessed on its own facts, and tribunals are expected to explore all reasonable procedural avenues before reaching the impossibility conclusion.

Practical Implications for SIAC Tribunals

• Tribunals bear the burden of exhausting alternatives. Before terminating, a tribunal should document its consideration of adjournment, bifurcation, procedural accommodations and any other mechanism that might allow proceedings to continue.
• Sanctions are not automatically fatal. Targeted sanctions affecting one party’s bank account may be distinguishable from comprehensive regimes affecting the entire dispute ecosystem. Early indications suggest that tribunals will need to conduct granular, fact-specific analysis.
• Reasons must be detailed. The SGHC’s endorsement of the tribunal’s “careful and methodical” reasoning suggests that cursory termination orders are vulnerable to challenge.
• The termination order is a final procedural act. It closes the arbitral proceedings but does not preclude fresh proceedings if circumstances change (e.g., sanctions are lifted).

Challenging a Tribunal Termination: Procedures, Remedies and Timing

Grounds to Challenge Termination of Arbitration in Singapore

A party dissatisfied with a termination order has several potential avenues, though none is straightforward.

• Setting aside under the International Arbitration Act: For international arbitrations, a party may apply to set aside the termination order on grounds analogous to those for setting aside awards, including that the party was unable to present its case, that the tribunal’s procedure was not in accordance with the parties’ agreement, or that the order deals with matters beyond the scope of the submission to arbitration.
• Breach of natural justice: If the tribunal failed to afford a party the opportunity to be heard on the impossibility question, or if it made the determination without adequate notice, a setting-aside application on natural justice grounds may be viable.
• Error of law (Section 49 of the Arbitration Act 2001): For domestic arbitrations, Section 49 permits an appeal to the SGHC on a question of law arising out of an award, with the agreement of all parties or with leave of the court. Whether a termination order constitutes an “award” for s.49 purposes is itself a contested question; the likely practical effect of DRL v DRK is that courts will treat substantive termination orders as amenable to s.49 review, though this point awaits definitive appellate confirmation.
• Jurisdictional challenge: If the tribunal lacked jurisdiction to terminate, for instance, because the arbitration clause did not incorporate the Model Law provisions, a jurisdictional challenge may be mounted.

Procedure and Timing

Applications to challenge a termination order must typically be filed within three months of the date on which the party received the order. The applicant should prepare a comprehensive evidence bundle including the termination order, all tribunal correspondence regarding the impossibility question, evidence of the sanctions regime (or other factual predicates), and any expert opinions on whether procedural alternatives existed. Counsel should also consider whether interim preservation measures are needed to protect the client’s position pending the court application, for example, a freezing order against the counterparty’s Singapore assets.

Strategic Considerations

Challenging a termination order is costly and uncertain. The deferential standard of review articulated in DRL v DRK means that applicants face an uphill battle. The practical calculus for most parties will involve weighing the cost of a challenge application against the prospects of fresh proceedings (if the underlying impossibility is resolved) or a negotiated settlement. Cross-border enforcement risk is another factor: even if a Singapore court were to reinstate the arbitration, practical impossibility may persist if the relevant sanctions regime remains in force.

Enforcing or Resisting Awards and Post-Termination Consequences

The consequences of a SIAC tribunal termination depend critically on the stage at which the termination occurs. Two scenarios illustrate the divergent outcomes.

Scenario A, Award already issued before termination: If the tribunal issued a partial or interim award before terminating the proceedings, that award survives the termination and can be enforced under the International Arbitration Act or, for Convention awards, the New York Convention framework. The enforcing party should act promptly, particularly if sanctions may later complicate execution against the award debtor’s assets.

Scenario B, Termination before any award: If the proceedings are terminated before any award is issued, the claimant is left without a substantive determination. The claimant’s options are limited: it may commence fresh arbitration proceedings if the impossibility is resolved, pursue remedies in a national court with jurisdiction, or negotiate a settlement. Enforcement of prior tribunal-ordered interim measures (such as preservation orders) becomes uncertain, as the termination may deprive those measures of their procedural foundation.

In both scenarios, parties should be alert to the interaction between the termination and foreign sanctions regimes. An award in favour of a sanctioned party may be unenforceable in jurisdictions that give effect to those sanctions, regardless of its validity under Singapore law. Conversely, a non-sanctioned party seeking to enforce an arbitration award in Singapore should confirm that enforcement does not contravene any sanctions legislation applicable in Singapore.

Drafting and Contract Design to Mitigate Impossibility Risk

The decision in DRL v DRK has accelerated interest in arbitration clause drafting that anticipates impossibility scenarios. Below are three model clause variants, each with guidance on negotiation positioning and enforcement risk. These clauses are designed for incorporation into SIAC-seated arbitration agreements.

Clause Bank

• Clause 1, Continuance Obligation (Balanced).
  Model language: “The tribunal shall not terminate the proceedings on grounds of impossibility under Article 32(2)(c) of the Model Law unless it has first considered and rejected, with written reasons, all reasonably available procedural alternatives, including adjournment for a defined period, bifurcation of issues, remote hearing, appointment of a procedural agent, and any other measure proposed by either party.”
  Negotiation note: This clause does not prevent termination but raises the procedural threshold, requiring the tribunal to document its consideration of alternatives. It is acceptable to most parties and is unlikely to be challenged as contrary to public policy.
  Enforcement risk: Low, the clause is procedural in nature and consistent with the tribunal’s existing obligations under the SIAC Rules 2025.
• Clause 2, Sanctions Carve-Out (Claimant-Protective).
  Model language: “In the event that international sanctions affect one or more parties’ ability to participate in the arbitration, the tribunal shall adjourn the proceedings for a period of not less than [12/18/24] months before considering termination for impossibility. The tribunal may extend the adjournment if there are reasonable grounds to believe that the sanctions may be modified or lifted.”
  Negotiation note: This clause protects claimants by buying time, but respondents may resist open-ended adjournments. A compromise is to cap the total adjournment period (e.g., 24 months) and include a mechanism for either party to request early resumption.
  Enforcement risk: Moderate, a tribunal may view an excessively long mandatory adjournment as inconsistent with efficient dispute resolution. Parties should calibrate the adjournment period to realistic sanctions timelines.
• Clause 3, Emergency Preservation Protocol (Protective for Both Parties).
  Model language: “If either party contends that continuation of the proceedings has become impossible, the tribunal shall, before making any termination order: (a) invite both parties to propose preservation measures; (b) issue an interim order preserving the status quo, including the preservation of evidence and the maintenance of any existing interim relief; and (c) afford both parties not less than [30] days to make submissions on the impossibility question.”
  Negotiation note: This clause is designed to ensure that even if termination occurs, the parties’ evidentiary and interim-relief positions are protected. It is generally acceptable to both claimants and respondents. Counsel should ensure that the preservation measures are enforceable under the applicable law and the SIAC Rules.
  Enforcement risk: Low, the clause supplements existing procedural safeguards without overriding the tribunal’s ultimate discretion.

Each of these clauses should be adapted to the specific transaction, the likely sanctions exposure of the parties, and the applicable institutional rules. Practitioners engaged in arbitration clause drafting in the post-DRL v DRK environment should also review their force majeure and hardship provisions for consistency with the arbitration clause.

Tactical Checklist for Counsel and In-House Teams

The following checklist is organised by timeframe and is designed for counsel and in-house legal teams responding to a tribunal termination order, or anticipating one.

Immediate Actions (0–14 Days)

• Preserve all documents, correspondence and evidence relating to the arbitration and the impossibility finding.
• Issue a written preservation notice to the counterparty and any relevant third parties (banks, custodians, document repositories).
• Review the termination order for any procedural irregularities, errors of law or natural justice concerns that could support a challenge application.
• Notify insurers (D&O, professional indemnity, political risk) and contract counterparties of the termination and its potential implications.
• Consider whether to seek urgent interim measures from the SIAC emergency arbitrator or the Singapore courts to preserve evidence or assets.

Short-Term Actions (2–8 Weeks)

• Obtain legal advice on the viability of a challenge application to the SGHC, including an assessment of the applicable standard of review and the evidentiary requirements.
• If a challenge is pursued, prepare the evidence bundle (termination order, tribunal correspondence, sanctions documentation, expert opinions on procedural alternatives).
• Request formal tribunal directions on the status of any interim awards or orders that pre-date the termination.
• Assess whether the factual basis for impossibility has changed or is likely to change (e.g., sanctions modifications, diplomatic developments).
• Explore settlement discussions with the counterparty, a termination may create mutual incentives for negotiated resolution.

Medium-Term Actions (8–26 Weeks)

• If a challenge application is filed, prepare pleadings and supporting affidavits, with particular attention to the standard of review and the tribunal’s reasoning.
• Monitor the sanctions regime for changes that could support an application to recommence proceedings.
• Update internal contract templates and arbitration clause language to incorporate the drafting protections discussed above.
• Brief the board or senior management on the termination, the challenge strategy, and the financial and reputational implications.
• Consider whether parallel proceedings in another jurisdiction (e.g., a national court with jurisdiction over the underlying contract) are appropriate as a fallback.

Comparison Table: Options After Tribunal Termination

Interpretive notes: The comparison above illustrates that no single remedy is decisive. In practice, parties will often pursue a combination, for instance, applying to set aside the termination order while simultaneously enforcing prior interim measures and monitoring the sanctions regime for changes. The choice of strategy depends on the specific facts, the value of the claims, and the client’s risk tolerance. Industry observers expect that challenges to termination orders will become more frequent in the near term, as parties test the boundaries of the DRL v DRK framework.
