Some of the most valuable things a company owns cannot be locked in a safe: its trade secrets, its customer lists, its pricing models, its unannounced deals, and the confidential terms of its disputes. When a departing director threatens to leak them, or a party to litigation is at risk of tipping off a wrongdoer, a company can ask the Singapore court for a confidentiality injunction or a gagging order, an order that restrains someone from disclosing or misusing confidential information. This guide explains what these orders are, the legal basis for them, who can apply, the process, and what happens after the order is made.
Confidentiality injunctions sit at the sharp end of commercial litigation and are often sought on an urgent, without-notice basis. This article is written for company directors and business owners in plain English, and it is general information rather than legal advice.
What these applications are
The phrase covers two related but distinct types of order that arise in company cases:
A confidentiality (non-disclosure) injunction restrains a person from disclosing, using or misusing confidential information belonging to the company, for example a former employee or director threatening to take trade secrets or a customer database to a competitor. A gagging order, in the litigation sense, restrains a party from informing others about something, most commonly to stop a respondent from tipping off a wrongdoer about the existence of a freezing or search order, or to stop a notified third party (such as a bank) from alerting its customer that its records have been ordered to be disclosed.
Both are usually sought as interlocutory injunctions, temporary orders to hold the position until trial, and both are prohibitory injunctions in that they forbid disclosure rather than compel action.
Legal basis
The court’s power to grant an injunction is found in section 4(10) of the Civil Law Act 1909, which allows the High Court to grant an injunction wherever it appears just or convenient. The procedure is set out in the Rules of Court 2021. The underlying right the injunction protects is usually the equitable duty of confidence (or an express confidentiality clause in a contract).
To protect information as confidential, the classic requirements are that the information has the necessary quality of confidence (it is not public knowledge), that it was imparted in circumstances importing an obligation of confidence (for instance, to a director or employee in the course of their role), and that there has been, or is threatened, an unauthorised use or disclosure of it. Where those elements are present, the court can restrain the misuse.
The test for an interim confidentiality injunction
For an interlocutory confidentiality injunction, the court applies the American Cyanamid framework: is there a serious question to be tried, would damages be an adequate remedy, and where does the balance of convenience lie? Confidential information is a classic case where damages are usually inadequate, because once a secret is out it cannot be made secret again, so the balance of convenience frequently favours granting the injunction to preserve confidentiality until trial.
Gagging orders attached to freezing and disclosure orders
Where a company obtains a Mareva (freezing) injunction or an Anton Piller (search) order, the order will often include a gagging provision preventing the respondent from telling anyone (other than for the purpose of getting legal advice) about the order for a limited period. The purpose is to prevent the respondent from dissipating assets or destroying evidence before the order bites. A similar gag can accompany a disclosure order against a bank or other third party, preventing it from tipping off the account holder while the company traces its assets.
Who can apply
A confidentiality injunction is typically sought by the company whose confidential information is at risk, against a departing or former director or employee, a joint-venture counterparty, a contractor, or anyone else bound by a duty of confidence. A gagging order is sought by the party obtaining the underlying freezing, search or disclosure order, usually a company pursuing a wrongdoer, and is directed at the respondent or the notified third party.
As with any interim injunction, the applicant must have a genuine cause of action (breach of confidence or breach of contract) and must give the undertaking as to damages required as the price of interim relief.
Step-by-step process
Step 1 – Move quickly and quietly. These orders are usually urgent. Where secrecy is essential (to prevent tipping off or the destruction of evidence), the application is made without notice (ex parte).
Step 2 – Commence proceedings and prepare the affidavit. The company starts a claim and files a summons for the injunction supported by an affidavit identifying the confidential information with precision, explaining how the duty of confidence arose and why disclosure is threatened.
Step 3 – Full and frank disclosure. On a without-notice application the applicant is under a strict duty to make full and frank disclosure of all material facts, including those unfavourable to its own case. Breaching this duty is one of the most common reasons a without-notice injunction is later discharged.
Step 4 – Give the undertaking as to damages. The applicant promises to compensate the respondent for loss if the injunction was wrongly granted; the court may require security.
Step 5 – The order and the return date. A without-notice order is granted for a short period with a return date at which the respondent can attend and argue for the order to be discharged or varied. A with-notice application proceeds after affidavits are exchanged.
Documents required
| Document | Purpose |
|---|---|
| Originating process / summons for injunction | Commences the claim and the interim application |
| Supporting affidavit | Identifies the confidential information and the threatened disclosure |
| Employment / director’s service contract or NDA | Establishes the express or implied duty of confidence |
| Evidence of the threatened or actual breach | Messages, resignation letters, downloads, or witness accounts |
| Draft order (including any gagging provision) | Sets out precisely what is restrained and for how long |
| Undertaking as to damages (and any security) | The applicant’s promise to compensate for wrongful restraint |
Timeline and indicative costs
| Stage | Indicative timing |
|---|---|
| Without-notice (urgent) order | Same day or within days in a genuine emergency |
| Return date / inter partes hearing | Usually within days to a few weeks of the first order |
| Duration of interim order | Until trial or further order (gagging period often time-limited) |
| Trial of the underlying breach of confidence | Several months to over a year |
Because these applications are urgent and evidence-heavy, and often run alongside a freezing or search order, costs can be significant, commonly from the low tens of thousands of dollars upward for a contested without-notice injunction, plus the applicant’s exposure under the undertaking as to damages. The value of the secret being protected, or the assets being preserved, has to justify the spend.
What happens after the order
Once granted, the respondent must comply, and breach of the injunction (including breach of a gagging provision) is a contempt of court punishable by fine or imprisonment. That is what gives a gagging order its teeth against tipping off. A without-notice order lasts only until the return date, at which the court decides whether to continue, vary or discharge it after hearing the respondent.
If the order is later discharged, or the applicant loses at trial, the respondent can enforce the undertaking as to damages through an inquiry to recover its loss. Confidentiality injunctions are also frequently resolved before trial, because once the information is secured and the springboard advantage removed, the parties often settle. The company should also consider whether a final injunction and delivery-up of confidential materials is needed at the end of the case.
Frequently asked questions
What exactly is a “gagging order”?
In company litigation it usually means an order stopping someone from telling others about something, most often a provision within a freezing or search order that stops the respondent from tipping off a wrongdoer, or a clause stopping a notified bank from alerting its customer. It can also refer to a straightforward order restraining disclosure of confidential information.
Can we stop a former director taking our client list?
Potentially yes. If the client list has the quality of confidence and was obtained in a position of trust, the court can restrain its use or disclosure. Directors also owe duties of confidence and good faith that survive their departure, which strengthens the claim.
Why must the confidential information be described precisely?
An injunction must be clear enough for the respondent to know exactly what they cannot disclose. Vague claims to “all confidential information” are difficult to enforce and may be refused, so the affidavit should identify the categories of information with care.
What is “full and frank disclosure” and why does it matter?
On a without-notice application, the applicant must tell the court all material facts, including those that hurt its own case, because the other side is not there to do so. Failing this duty is a leading reason such injunctions are set aside on the return date.
