Yes. A Singapore company’s constitution binds the company and every member as if each had signed it (section 39(1) of the Companies Act 1967), so a shareholder whose own rights under it are about to be ignored can ask the High Court to stop the breach, usually by injunction and declaration. The court is most willing to step in where the clause protects a personal right of the member, where the company has no power to do the act at all, or where the act is a disposal of the whole undertaking without shareholder approval. Purely internal irregularities that the majority could fix are a different matter. Speed matters: once shares are transferred or a loan is signed, undoing it is harder and slower.
Why can a shareholder enforce the constitution at all?
Section 39(1) of the Companies Act 1967 says a registered constitution binds the company and its members as if each member had signed and sealed it and agreed to observe all its provisions. It is a statutory contract, so if the board is about to do something the constitution forbids, a member can treat that as a threatened breach of contract and ask the court to restrain it.
The court’s general power to grant an injunction, including an interim one, comes from section 4(10) of the Civil Law Act 1909, which allows an injunction wherever it appears just or convenient. That power still depends on the applicant having a real legal right to protect, which is why the first question is always whose right the clause actually protects.
This article deals with stopping the company or its board from doing something the existing constitution prohibits. If the problem is that nobody agrees what a clause means, see our guide on asking the court what your company’s constitution means. If the dispute is about a meeting called on short notice or without a quorum, our separate guide on restraining a defective general meeting or resolution covers that ground.
Which breaches can a shareholder ask the court to stop?
Not every departure from the constitution gives an individual shareholder a claim. Courts generally sort clauses into three groups, and the group decides whether you can sue in your own name.
| Type of clause | Typical examples | Who can usually enforce it |
|---|---|---|
| Personal rights of members | Pre-emption on transfer, a right to vote, a right to nominate a director, a requirement that a named member’s consent is obtained, dividend rights attached to your shares | The member whose right is affected, in their own name |
| Internal management rules | How board meetings are run, minor procedural steps the majority could easily repeat or ratify | Usually only the company; the court rarely intervenes for a single shareholder if the majority could put the matter right |
| Rights held in another capacity | A clause promising a person a job, a fee or a seat as company solicitor or adviser | Generally not enforceable through section 39, because the constitution binds members only in their capacity as members |
The middle category is the one that defeats many applications. If the complaint is that the board skipped a procedural step which a general meeting could simply approve afterwards, the court may decide there is no point stopping it. The answer changes where the clause requires the consent of a particular shareholder or a special majority that the board does not have, because ratification by a simple majority cannot supply that consent.
Are there statutory routes as well as the contract claim?
Yes. Two provisions of the Companies Act 1967 give a member a specific right to ask the court to restrain the company or its directors.
- Acts beyond the company’s power, section 25. A transaction is not invalid merely because the company lacked the capacity or power to enter into it (section 25(1)). But section 25(2)(a) preserves a member’s right to bring proceedings to restrain the company from doing the act. Where the act is to be done under a contract, section 25(3) allows the court to set aside and restrain performance if all parties to the contract are before the court and it is just and equitable, and the court may award compensation, though not for anticipated profits.
- Disposal of the whole or substantially the whole undertaking, section 160. Despite anything in the constitution, directors must not carry out a proposal to dispose of the whole or substantially the whole of the company’s undertaking or property without shareholder approval in general meeting (section 160(1)). Section 160(2) lets the court, on a member’s application, restrain the directors from entering into a transaction in breach. A buyer who dealt for value without actual notice of the breach is protected (section 160(3)), which is another reason to apply before completion.
Personal claim, oppression or derivative action: which route fits?
The same set of facts can often be framed in more than one way, and the choice affects what you must prove and what the court can order.
| Route | Best suited to | What the court can do |
|---|---|---|
| Claim on the constitution under section 39(1) | A clear clause protecting your personal rights as a member | Declaration of the breach and an injunction restraining it |
| Oppression, section 216 | A pattern of conduct, or a resolution passed or proposed, that is unfairly prejudicial to you as a member | Any order it thinks fit, including restraining an act, cancelling or varying a transaction or resolution, regulating future conduct or ordering a buy-out |
| Derivative action, section 216A | A wrong done to the company itself, such as directors misusing company assets | Relief in favour of the company, after the court grants permission to sue in its name |
| Section 25 or section 160 application | An act outside the company’s powers, or a sale of the whole business without approval | Restraint of the act or transaction |
Where a constitutional breach is one episode in a wider campaign to squeeze out a minority, lawyers often plead section 216 alongside the contract claim, because section 216(2) gives the court a much wider choice of remedy. For harm to the company rather than to you personally, see our guide to bringing a derivative action under section 216A.
How do you get an urgent order before the board acts?
Under the Rules of Court 2021, which govern civil proceedings started on or after 1 April 2022, injunctions are dealt with in Order 13. An application can be made by originating application or by summons in existing proceedings. In a genuinely urgent case it can be made without notice to the other side, and even before the main proceedings are filed, with the main originating process to follow. A without-notice order is normally short and comes back to court quickly for a hearing with both sides present.
At the interim stage the court does not decide who is ultimately right. In broad terms it asks whether there is a serious question to be tried, and then where the balance of convenience lies: which side would suffer harm that money could not properly repair if the order were wrongly granted or wrongly refused. The applicant is normally required to give an undertaking to pay the other side’s losses if the injunction later turns out to have been wrongly granted. A without-notice applicant also owes a strict duty to disclose every material fact, including the ones that hurt their case. Unexplained delay is one of the most common reasons interim relief is refused.
If the dispute is already a section 216 claim, our guide to interim injunctions in section 216 cases explains how that variant works.
What are the practical steps?
- Get the current constitution. Download it from Bizfile and check for later amendments lodged with ACRA. Do not rely on a draft or an old copy.
- Pin down the clause and the threatened act. Identify exactly which provision will be broken, by whom and when. Note any board papers, emails or notices showing the plan.
- Check any shareholders’ agreement. It may contain the same restriction, a dispute resolution clause or an arbitration clause that affects where the claim must be brought.
- Write to the board. Where time allows, put the directors on notice in writing, identify the clause and ask for a written undertaking not to proceed by a short deadline.
- Brief a lawyer early. An injunction application needs a supporting affidavit, a draft order and a decision on the undertaking as to damages.
- Apply, with or without notice. Your lawyer will decide whether the urgency justifies a without-notice application or whether the board should be given notice.
- Keep the company records accurate. If an order is made, the company secretary should note it in the minutes and make sure no filings are lodged that would breach it.
Documents checklist
- The current constitution and every special resolution amending it
- Any shareholders’ agreement, investment agreement or side letter
- The register of members and your share certificates or Bizfile business profile
- Board resolutions, notices, minutes, emails or messages showing the proposed act
- Draft contracts, loan documents, transfer forms or ACRA filings the board intends to sign or lodge
- Your letter to the board and any reply
- Evidence of the harm that would follow if the act went ahead, and why money compensation would not be adequate
Example: a secured loan the constitution does not allow
Example: A trading company has three shareholders. Its tailored constitution says the company may not grant security over its warehouse without the written consent of every member holding at least 20 percent of the shares. Two directors, who together control 60 percent, arrange a loan from a company owned by one of them, to be secured by a mortgage over the warehouse. The third shareholder, who holds 40 percent, learns about it from a draft facility letter circulated three days before signing.
The consent requirement protects a personal right of a substantial member, not an internal procedure, and the majority cannot ratify around it because the consent is the minority’s to give. The third shareholder writes to the board demanding an undertaking not to sign. When none is given, she applies for an interim injunction restraining the company from executing the mortgage until the claim is decided. Because the lender is connected to a director, its knowledge of the restriction can be shown, and she also pleads section 216 on the basis that the loan is designed to benefit the majority at her expense.
What should directors do if they receive a demand like this?
Directors who receive a credible demand should pause the act, read the clause with the company secretary and take legal advice before proceeding. Pressing ahead after a clear warning invites an injunction and a costs order, and can expose directors to arguments that they acted for an improper purpose. If the constitution genuinely stands in the way of a sound commercial plan, the proper route is usually to obtain the consents it requires or to amend it by special resolution, bearing in mind that an amendment aimed at one shareholder can itself be challenged. Where the problem is a purely procedural slip, section 392 of the Companies Act 1967 allows the court to declare a proceeding not invalid in suitable cases, provided no substantial injustice has been or is likely to be caused.
Frequently asked questions
Can a director who is not a shareholder enforce the constitution?
Generally not through section 39, because the statutory contract binds the company and its members in their capacity as members. A director’s position usually depends on the Companies Act, the director’s appointment terms and the general law of directors’ duties. A director who is also a shareholder can rely on the rights that come with the shares.
The act has already happened. Is it too late?
Not necessarily, but the remedy changes. Instead of a simple restraining order you may need a declaration, an order setting the transaction aside, rectification of the register of members or relief under section 216. Rights of innocent third parties, such as a buyer protected by section 160(3), may limit what the court can undo. If the act was an unauthorised share issue, see our guide on challenging an allotment made without proper authority.
Do I have to sue the directors personally?
The company is the usual defendant because it is the party bound by the constitution. Directors are often joined where the order needs to bind them personally or where a claim is also made against them, for example under section 216. Your lawyer will advise who must be named so that any order is effective.
What does the undertaking as to damages mean for me?
It is a promise to the court that, if the injunction is later found to have been wrongly granted, you will pay the losses it caused the company or others. It is a real financial exposure.
