A French company loses a SIAC arbitration in January 2027. The award orders it to pay 6,800,000 Singapore dollars, and it is convinced that the tribunal decided a question it had not been asked and set aside a central expert report without explanation. Two routes are open, with different costs, timetables and prospects: attacking the award before the court of the seat, or waiting and resisting enforcement in France. The choice is made in the days following notification, not later.
This page deals with the challenge in Singapore: the time limit, the grounds opened by the Model Law and those Singapore law adds, the courts’ consistent policy of restraint, the option for the Singapore International Commercial Court, the reform under way whose outcome is not known, and how all of this fits with a defence in France.
1. Three months, and the clock starts on receipt
The seat designates the court that may set the award aside. An award made in Singapore therefore falls to the General Division of the High Court or, at the parties’ option, to the Singapore International Commercial Court, and the UNCITRAL Model Law, which has the force of law in Singapore, confines an application to set aside to three months from receipt of the award.
That period looks comfortable and is not. Within those three months the award must be obtained, analysed by counsel admitted before the Singapore court, the grounds settled, the record of the arbitral proceedings assembled and the application filed. For a French legal department discovering the defeat, the usable time is measured in weeks.
A practical constraint is added and regularly takes parties by surprise: the award is released to the parties by the secretariat only after the costs of the arbitration have been paid (SIAC Rules 2025, rule 52.5). The losing party that has not funded its share, or whose opponent advanced the whole of the costs, may therefore lose several days before even reading the document it must challenge.
2. The grounds opened by the Model Law
The list is closed and it is short. An award may be set aside only if the applicant furnishes proof of the incapacity of a party to the arbitration agreement or of its invalidity, of the lack of proper notice of the appointment of an arbitrator or of the proceedings, or of inability to present its case, of the fact that the award deals with a dispute not contemplated by the agreement or contains decisions beyond its terms, or of the irregular composition of the tribunal or of the procedure (UNCITRAL Model Law, article 34(2)(a)).
Two further grounds may be raised by the court of its own motion: non arbitrability of the dispute under the law of the State concerned and conflict of the award with the public policy of that State (article 34(2)(b)). That last ground, familiar to a French lawyer, does not receive in Singapore the extension it has in Paris, where the Court of Appeal accepts to reopen the facts in matters of corruption and money laundering.
What the list does not contain matters as much as what it does. Error of law is not there. Error in the assessment of the facts is not either. A party that simply considers the tribunal got it wrong has, under Singapore law as it stands, no remedy, and that is precisely the point the 2025 public consultation puts up for discussion.
3. The two grounds specific to Singapore law
The Singapore legislature added two cases to the Model Law grounds. Notwithstanding article 34(1), the High Court may set aside an award where it was induced or affected by fraud or corruption, or where a breach of the rules of natural justice occurred in connection with the making of the award by which the rights of a party have been prejudiced (International Arbitration Act 1994, section 24).
The second ground is the one most often invoked, and also the most misunderstood. Natural justice covers two classical requirements: that the arbitrator be disinterested and impartial, and that the parties have been given the opportunity to be heard. It must still be shown that the breach actually prejudiced the rights of the party relying on it: the statute requires prejudice, not a formal irregularity.
That is where complaints belong about a document set aside without discussion, a point decided without the parties having been able to address it, or reasoning that departs from the positions argued. The complaint is real, but it comes up against case law that refuses to convert review into rehearing.
4. The Singapore judge’s policy of restraint
Recent case law confirms a policy of non intervention, and it must be explained to the client before costs are incurred. A party that chose not to take part in the arbitration cannot base a challenge on the tribunal’s failure to decide questions it abstained from raising (DEM v DEL [2025] SGCA 1, [2025] 1 SLR 29). Procedural abstention creates no grievance: it consumes it.
The court likewise refuses to intervene during an arbitration against a procedural decision of the SIAC Registrar. Article 5 of the Model Law, which excludes judicial intervention in matters it governs except where it so provides, requires a two stage analysis: is the matter governed by the Model Law, and is intervention authorised there (DMZ v DNA [2025] SGCA 52, [2025] 2 SLR 398).
The facts of that second case deserve to be known by legal departments, because they illustrate a concrete risk. The claimant filed its request for arbitration a week before the limitation period expired. The SIAC asked it to identify the arbitration clauses relied upon, it did so two days later, and the Registrar fixed the date of commencement of the arbitration on the day of that clarification, after the probable expiry of the period. A week’s margin is not a margin.
Both decisions trace the same line, and it can be put in one sentence: the Singapore judge reviews the regularity of the proceedings, never the correctness of the result. The practitioner draws a method from it. A challenge that begins by explaining why the tribunal was wrong is lost before it is argued. One with prospects starts from the conduct of the proceedings, identifies the precise moment when a party could not address a point the award decides, and shows that this silence changed the outcome. The difference is not rhetorical but structural: the first complaint does not exist in law, the second is one of the two Singapore law added.
5. What scrutiny of the draft award takes away from a challenge
A mechanism peculiar to institutional arbitration reduces the prospects of setting aside upstream. Before making its award, the tribunal must submit it in draft to the SIAC secretariat and inform the parties of the date of that submission, no later than ninety days after the last submission or hearing ordered, unless the Registrar decides otherwise (SIAC Rules 2025, rule 53.2).
The Registrar may then suggest modifications of form and draw the tribunal’s attention to points of substance, without affecting its freedom to decide (rule 53.3). In practice that scrutiny corrects omissions in the reasoning, inconsistencies in the operative part and failures to address a head of claim, which is exactly the class of defects on which challenges succeed.
For a party contemplating a challenge, the consequence is unwelcome but worth absorbing: the award it receives has already been reviewed by an institution whose business is to make awards enforceable. Challenges based on a simple failure to give reasons therefore have little prospect, and the effort must go to what scrutiny cannot repair, namely the conduct of the proceedings themselves.
6. Bringing the challenge before the Singapore International Commercial Court
The SICC hears proceedings relating to international commercial arbitration that the General Division may hear under the International Arbitration Act 1994 (Supreme Court of Judicature Act 1969, section 18D(2)(a)). Procedure there is governed by Order 23 of the SICC Rules 2021: the application is made by originating application, supported by a single affidavit setting out the grounds and exhibiting the arbitration agreement and the award.
Two routes lead there. The parties may have stipulated it in their clause, the SIAC model clause reserving an option to that effect, and that is the safer route. Failing that, a transfer from the General Division remains possible. The SICC’s procedural guide uses, as orientation criteria, the absence of a Singaporean party or the presence of at most one where there are three or more, and a value of the dispute or award of at least 10,000,000 Singapore dollars.
The interest for a French party is concrete. The bench includes international judges, registered foreign counsel may make submissions on points of foreign law, and the procedure is designed for litigants who do not practise Singapore law daily. Where the dispute turns on the interpretation of a contract governed by French law, that facility changes how the case is run.
7. A reform under way, with an unknown outcome
The Singapore Ministry of Law opened a public consultation from 20 March to 2 May 2025 on the international arbitration regime and on the International Arbitration Act 1994. Eight questions are asked, several of which would directly affect challenge strategy.
Among them are the introduction of a right of appeal on a question of law available by agreement of the parties, a reduction of the three month period for applying to set aside, a requirement of leave to appeal to the Court of Appeal against a decision on setting aside, the costs regime for unsuccessful challenges, and codification of the method for determining the law applicable to the arbitration agreement.
No text had been adopted at the time of writing, and we do not know which proposals will be retained or what transitional rules will accompany them. A company signing a clause today with a Singapore seat should therefore factor in that the remedies regime may change during the life of its contract, and draft its clause so as to be able to accommodate, or exclude, a possible option of appeal on a point of law.
8. Challenging in Singapore or resisting in France
A losing party whose assets are in France has a second line of defence, and it must be weighed before incurring an expensive challenge in Singapore. The Paris Court of Appeal may refuse recognition or enforcement only in the five cases of article 1520 of the code of civil procedure, but those cases largely overlap the Model Law grounds, and one of them, conflict with international public policy, gives rise in France to more intrusive review than in Singapore.
The calculation is complicated by an asymmetry. Setting aside in Singapore does not prevent enforcement in France, since French law does not treat that as a ground of refusal. Conversely, refusal of enforcement in France does not affect the award elsewhere. The two proceedings therefore do not replace one another: they protect different assets.
The decision is made on a map and on a budget. If the bulk of the attachable assets is French or European, resisting enforcement costs less and is argued in a language and before a court the company knows. If the debtor has assets in Asia, India or the Middle East, where the award will travel, setting aside at the seat retains strategic value that a French defence does not replace. In most serious cases, both are run in parallel.
One last factor bears on that choice, and it is financial. A challenge in Singapore requires local counsel, translation of the record of the arbitral proceedings and a timetable the party does not control, whereas defending against enforcement is run from Paris, within the one month appeal period extended by two months for parties resident abroad (code of civil procedure, articles 1525 and 643). At equal stakes, the cost gap between the two strategies is rarely less than a factor of two, which settles nothing on its own but must be on the table at the first meeting.
Frequently asked questions
What is the time limit for bringing a challenge
Three months from receipt of the award, under the UNCITRAL Model Law, which has the force of law in Singapore. That period is both short and treacherous: the award is released to the parties only after the costs of the arbitration have been paid (SIAC Rules 2025, rule 52.5), and counsel admitted before the Singapore court must then be instructed, the grounds settled and the record assembled. The public consultation opened in 2025 indeed contemplates shortening it.
Can all remedies be waived in advance
The rules provide that the parties are deemed to have agreed that the award is final and binding from the date it is made and irrevocably waive any appeal, review or recourse to any court, but they qualify that waiver decisively: insofar as such waiver may validly be made (rule 51.6). Its real scope therefore depends on the law of the seat, and a waiver clause should never be accepted as a guarantee.
Does setting aside in Singapore prevent enforcement in France
No. Setting aside in the country of origin is not among the five cases in which the Court of Appeal may refuse recognition or enforcement (code of civil procedure, articles 1520 and 1525), and the Court of Cassation holds that an award set aside at the seat remains enforceable in France (Cass. 1re civ., 23 March 1994, no. 92-15.137). A debtor with French assets cannot therefore be content with winning in Singapore: it must also defend itself in Paris.
Why bring the challenge before the SICC rather than the High Court
Because that court is designed for foreign litigants. The SICC hears proceedings relating to international arbitration that the General Division may hear under the International Arbitration Act 1994 (Supreme Court of Judicature Act 1969, section 18D(2)(a)), under its own procedure (SICC Rules 2021, Order 23). Its bench includes international judges and registered foreign counsel may make submissions on points of foreign law, which matters where the contract is governed by French law. The option is stipulated in the clause, failing which a transfer is needed.
Will the announced reform apply to contracts already signed
We do not know, and nobody can say today. The consultation open from 20 March to 2 May 2025 has produced no text to date, neither on the substance of the proposals nor on their transitional rules. The reasonable precaution is to treat the remedies regime as liable to change during the life of the contract, and to check the state of the text when a dispute becomes likely rather than at signature.
