The whole point of a court-sanctioned scheme of arrangement is finality. Once the High Court sanctions a scheme under Section 210 of the Companies Act 1967, every creditor in the affected class is bound — including those who voted against, abstained, or didn’t show up at all. That binding effect, plus the worldwide moratorium under the Insolvency, Restructuring and Dissolution Act 2018 (IRDA), is what makes Singapore schemes commercially powerful. It also means that the bar to challenging a sanctioned scheme is high — but not impossibly so.
This article walks through the grounds on which a Singapore scheme of arrangement can be challenged or set aside, when the challenge can be brought (pre-sanction vs post-sanction), what the courts have said about each ground, and what a credibly opposed scheme looks like in practice. It is written for directors, creditors and shareholders who may need to oppose a scheme — and for companies trying to insulate their own scheme against a likely challenge.
What “challenging” a scheme means
A scheme of arrangement can be challenged at three different stages, each with different rules:
- Convening stage: opposing the convening order under Section 210 (and the associated explanatory statement) before the meetings.
- Sanction stage: opposing the sanction of the scheme after the meetings, on grounds of class composition, fairness, disclosure, or jurisdiction.
- Post-sanction: applying to set aside the sanction order, typically on grounds of fraud or material non-disclosure that emerged after sanction.
Most reported Singapore challenges have come at the sanction stage — the convening stage is generally too early for substantive merits arguments, and post-sanction challenges face a steep burden because of the public-confidence value of sanctioned schemes.
Grounds for challenging a scheme
1. Improper class composition
The most common ground. A scheme is only valid if creditor classes are properly composed — i.e. each class must contain creditors whose rights are “not so dissimilar as to make it impossible for them to consult together with a view to their common interest.” If a class is improperly composed (e.g. lumping secured and unsecured creditors together, or treating creditors with different commercial entitlements as a single class), the entire vote is suspect.
For more on the class composition test, see our guide on creditor classes.
Class composition is typically litigated at convening stage but can be reopened at sanction if new information emerges.
2. Inadequate explanatory statement / material non-disclosure
Section 211 of the Companies Act requires that creditors be sent a statement that fairly discloses the effect of the scheme, the rationale, and material interests of directors and others involved. A scheme can be challenged where the explanatory statement:
- Omits material adverse information about the company’s financial position;
- Fails to disclose conflicts of interest of directors or sponsors;
- Misrepresents the comparator (the alleged liquidation outcome);
- Glosses over key terms in the scheme that disadvantage particular classes.
Singapore courts have set aside schemes where disclosure was found materially deficient, but the threshold is real materiality — minor errors or stylistic omissions are not enough.
3. Lack of statutory majority
Section 210 requires a majority in number AND at least 75% in value of creditors present and voting in each class. If the majorities are not in fact met — for example because some votes are challenged as invalid (proxy issues, lack of proof of debt, alleged related-party vote-stacking) — the sanction can be challenged on jurisdictional grounds.
4. Unfairness — the “blot on the scheme” test
Even where the statutory majorities are met, the court has a residual discretion to refuse sanction if the scheme is one that no intelligent and honest creditor could reasonably approve. The court asks: is there a “blot” on the scheme — a feature that makes it inherently unfair to a class of creditors? Examples include:
- Releasing third-party guarantors (especially shareholders) for inadequate consideration;
- Disproportionate treatment of creditors with materially similar legal rights;
- Provisions that leave too much discretion to the company’s controllers post-sanction;
- Tax-driven structures that disadvantage one class for the benefit of another.
5. Improper purpose
A scheme used as a tactical weapon — e.g. to defeat specific litigation, gerrymander voting, or shield directors from personal liability — rather than as a genuine attempt to compromise with creditors, can be refused sanction. The court looks at the substance of the scheme, not just its form.
6. Vote manipulation and tactical claims
Related-party creditors voting in their own class can swing a vote against arm’s-length creditors. Singapore courts have, in recent years, been willing to discount or disregard related-party votes where it appears the related party voted to serve interests other than as a creditor (e.g. to preserve a director’s equity). Allegations of vote-buying or selective sweeteners outside the scheme are also fertile ground for challenge.
7. Lack of sufficient connection (foreign companies)
For schemes by foreign-incorporated companies, the court must be satisfied of “sufficient connection” with Singapore. A challenger can argue the connection is contrived — for example, a sole Singapore-law contract added solely to manufacture jurisdiction. Where the connection is found insufficient, the court will decline to sanction. See our companion piece on what the judge considers at sanction.
8. Fraud or misrepresentation (post-sanction)
A sanctioned scheme can be set aside post-sanction where it was procured by fraud — typically discovery that the company misrepresented its financial position, suppressed material litigation, or fraudulently misled the court about creditor support. The challenger must show that, but for the fraud, the court would not have sanctioned.

Who can challenge
The applicants for challenge are usually:
- Creditors who voted against the scheme;
- Creditors who were excluded from voting on alleged class composition errors;
- Shareholders whose equity is being diluted or extinguished;
- Counter-parties to contracts purportedly being released without their consent;
- Foreign creditors challenging recognition in their home jurisdiction (a parallel attack, not a direct Singapore challenge).
Standing to challenge is broadly accepted in Singapore — the court will hear any party with a real economic interest affected by the scheme.
The step-by-step challenge process
Step 1 — Early notice
If you intend to oppose, write to the scheme company and its lawyers early. Most contested Singapore schemes feature pre-action correspondence weeks before the sanction hearing. Reserve your rights, request the underlying documents, and ask for clarification on the points you intend to challenge.
Step 2 — Appear at the convening hearing
Class composition objections must usually be raised at the convening hearing under Order 23 ROC 2021. The court will not normally revisit class composition at sanction if the issue could have been raised earlier. Show up — even with limited information — to preserve the point.
Step 3 — File an opposition affidavit
Set out the specific grounds of challenge with primary evidence: copies of the explanatory statement annotated with omissions, calculations showing improper vote-counting, evidence of related-party vote-stacking. The court is heavily document-driven; persuasive challenges are evidenced challenges.
Step 4 — Sanction hearing
This is the main hearing. The challenger will typically be granted oral submissions even where they did not vote against in the meeting, provided they have economic interest. The court tests both jurisdictional points (majorities, class composition) and discretionary points (fairness, disclosure).
Step 5 — Appeal
Sanction or refusal can be appealed to the Court of Appeal. Where the sanction order has been used as the basis for issuing new securities or distributing cash, an appeal often comes with a stay application to prevent irreversible implementation. Stays are not automatic.
Step 6 — Post-sanction set-aside
Under Order 23 r.7 ROC 2021, applications to set aside on grounds of fraud or material non-disclosure must be made within a reasonable time of discovery, supported by clear evidence of what was concealed and what the court would have done differently if it had known.
Documents required (table)
| Document | Purpose |
|---|---|
| Opposition affidavit | Primary evidence and grounds |
| Proof of debt or share interest | Establish standing |
| Annotated explanatory statement | Highlighting omissions or misstatements |
| Voting register analysis | For majority or class composition challenges |
| Expert valuation report | For “unfairness” or “blot on scheme” challenges |
| Comparator analysis (liquidation outcome) | To show creditors would do better in liquidation |
| Foreign law evidence | For sufficient-connection or recognition challenges |
| Correspondence record | Showing notice given and issues raised early |
Timeline and costs (table)
| Stage | Typical duration | Indicative cost (S$) |
|---|---|---|
| Pre-action correspondence and review | 2–4 weeks | 20,000–80,000 |
| Opposition at convening hearing | 1–3 weeks | 30,000–80,000 |
| Preparation of opposition affidavit and evidence | 4–8 weeks | 80,000–250,000 |
| Sanction hearing | 1–3 days hearing | 50,000–250,000 |
| Appeal (if any) | 3–9 months | 100,000–500,000 |
| Post-sanction set-aside application | 3–9 months | 100,000–500,000 |
A serious sanction challenge typically costs S$200,000–S$600,000 to first instance. Appeals add materially more. Costs orders generally follow the event — the loser pays. The court can also order a challenger to provide security for costs if there’s a real risk of unrecoverable costs.
What happens after the challenge
If the court refuses sanction, the scheme fails. The company is back to negotiation — often under tighter time pressure because the moratorium will not be granted indefinitely. The company may try a revised scheme curing the defects, or fall into judicial management (see Judicial Management vs Winding Up in Singapore) or winding up.
If sanction is granted despite the challenge, the challenger may appeal. In the meantime, the scheme implementation proceeds — including any debt-for-equity swap, new debt issuance, or distributions.
If a post-sanction set-aside succeeds, the legal effect is that the scheme is treated as never sanctioned. Distributions made under it may be recoverable. This is rare but extraordinarily disruptive when it happens.
Frequently asked questions
If I voted in favour, can I still challenge the scheme?
Generally no, unless your favourable vote was procured by misrepresentation or material non-disclosure. Voting in favour is treated as informed consent to the scheme.
Can a minority shareholder challenge?
Yes, where the scheme affects shareholders (e.g. a debt-for-equity scheme that materially dilutes existing equity). Section 210 schemes can be member schemes as well as creditor schemes.
How quickly do I need to move?
Class composition: at convening. Fairness / disclosure: at sanction. Fraud: within a reasonable time after discovery. The single most common reason challenges fail is timing — turning up too late with too little.
Are challenges to schemes common?
Substantive challenges are not common but are increasing as Singapore’s restructuring caseload grows. The recent appellate jurisprudence has clarified — and in some respects raised — the standards for sanction, making well-evidenced challenges meaningfully viable.
Can I challenge a Singapore scheme from outside Singapore?
Yes — through Singapore counsel. You don’t need to be a Singapore resident or have a Singapore branch to challenge a Singapore scheme. Foreign creditors regularly oppose Singapore schemes, and the court is content to hear them.
What’s the difference between challenging a scheme and applying for a judicial management order?
Challenging a scheme is a defensive move — you’re trying to defeat the company’s restructuring proposal. Applying for judicial management is constructive — you’re trying to replace the company’s existing management with a court-appointed judicial manager. See our guide on what judicial management is and when it applies.
