Mandatory Injunctions in Australia: When a Court Will Order Someone to Act
Summary
Most injunctions stop something happening. A mandatory injunction compels a positive step. This guide explains the higher standard for urgent mandatory relief, when a court will compel performance rather than leave you to damages and the practical points that decide these applications.
Key Takeaways
- A prohibitory injunction restrains conduct. A mandatory injunction compels it. The same dispute can call for both.
- Mandatory injunctions are discretionary and are treated with more caution than prohibitory ones, because compelling positive action carries a greater risk of injustice if the court turns out to be wrong.
- For an urgent mandatory injunction before trial the applicant must usually show more than a serious question to be tried. The court looks for a high degree of assurance that the order will be seen at trial to have been rightly granted, a standard drawn from Shepherd Homes Ltd v Sandham and applied in Australia in Businessworld Computers Pty Ltd v Australian Telecommunications Commission.
- Damages must be an inadequate remedy. If money fairly compensates you, the court will usually leave you to it rather than compel performance.
- An applicant must give the usual undertaking as to damages, a promise to compensate the other side if the injunction is later found to have been wrongly granted.
- Delay, unclean hands and orders the court cannot practically supervise are the most common reasons mandatory relief is refused.

Most injunctions stop something happening. A mandatory injunction is the opposite. It is a court order that compels a person to take a positive step: to remove the structure, return the property, restore the access or reconnect the supply. Because the court is forcing action rather than holding the position, mandatory injunctions are harder to obtain than ordinary prohibitory ones, and the test the court applies before trial is more demanding.
This guide explains what a mandatory injunction is, the higher standard that applies to urgent mandatory relief, when a court will compel performance rather than leave you to damages and the practical steps that decide these applications. For the general procedure on urgent and interlocutory relief, see our guide to urgent injunctions in Australia.
What a Mandatory Injunction Actually Is
An injunction is a court order directed at a person. A prohibitory injunction tells them to stop: stop using the confidential information, stop trading in breach of the restraint, stop calling on the bank guarantee. A mandatory injunction tells them to act: remove the structure that encroaches on the boundary, return the documents, reinstate the dealer agreement or reconnect the service that was wrongly cut off.
The distinction matters because the courts approach the two differently. When a court restrains conduct it usually preserves things as they are while the dispute is worked out. When a court compels conduct it changes the position, sometimes at real cost and effort to the party ordered, and if the court has misjudged the case that change can be hard to undo. For that reason mandatory relief attracts more caution, and the applicant carries a heavier persuasive burden, particularly before trial.
The Two Settings: Before Trial and at Trial
Mandatory injunctions arise in two very different settings, and the test is not the same in each.
An interlocutory mandatory injunction is sought urgently, before the case has been tried, to compel action in the meantime. This is the hard one. The court is being asked to force a positive step on a contested and untested set of facts.
A final mandatory injunction is made at the end of the case, once the rights have been determined. Here the question is no longer how confident the court is about the merits, because the merits have been decided. The question becomes whether compelling performance is the right remedy or whether the court should award damages instead.
How Mandatory Injunctions Compare
| Injunction | What it does | Test the court applies | Practical difficulty |
|---|---|---|---|
| Prohibitory, interlocutory | Stops conduct until trial | Serious question to be tried, damages inadequate and balance of convenience (Beecham; ABC v O'Neill) | Moderate. Preserves the position |
| Mandatory, interlocutory | Compels conduct until trial | The same factors plus a high degree of assurance the order was rightly granted (Shepherd Homes; Businessworld Computers) | High. The court is forcing action on untested facts |
| Prohibitory, final | Permanently restrains conduct | Rights established at trial, then discretionary relief | Moderate |
| Mandatory, final | Permanently compels conduct | Rights established, damages must be inadequate and performance must be workable | High where supervision or hardship is in issue |
The Test for an Urgent Mandatory Injunction
The starting point for any interlocutory injunction in Australia is the inquiry the High Court set out in Beecham Group Ltd v Bristol Laboratories Pty Ltd (1968) 118 CLR 618 and restated in Australian Broadcasting Corporation v O'Neill (2006) 227 CLR 57. The court asks whether there is a serious question to be tried, whether the applicant would suffer injury for which damages are not an adequate remedy and whether the balance of convenience favours granting relief.
For a mandatory interlocutory injunction the courts apply that framework with an extra layer of caution. On an urgent application, as opposed to a trial, a court is far more reluctant to grant a mandatory injunction than a comparable prohibitory one, and usually requires a high degree of assurance that at the trial it will appear the injunction was rightly granted. That principle comes from Shepherd Homes Ltd v Sandham [1971] Ch 340 and was applied in Australia by Gummow J in Businessworld Computers Pty Ltd v Australian Telecommunications Commission (1988) 82 ALR 499, where his Honour framed the task as choosing the course that carries the lower risk of injustice if the applicant ultimately fails. The reason is practical and fair. An order compelling action can put the respondent to significant cost and disruption, and if the applicant loses, some of that may never be recovered. The higher the stakes of being wrong, the more sure the court wants to be before it acts.
This does not make a mandatory injunction impossible to obtain quickly. It means the evidence has to be stronger and clearer than it would be for a simple order to stop something. A clear right, an obvious breach and a pressing need are the kind of facts that meet the standard.
Injunction or Damages: the Question That Comes First
Before a court will compel performance it asks whether damages would be an adequate remedy. If money can fairly put you back in the position you would have been in, the court will usually award money rather than force the other side to act. Mandatory injunctions are reserved for cases where damages are not enough: where the loss is hard to measure, where the harm is continuing or where what you have lost is not the kind of thing money replaces, such as access to premises you cannot trade without.
The practical questions the court weighs are these. Are damages an adequate remedy. How great is the hardship of compelling performance against the harm of refusing it. Can the order be expressed clearly enough that the respondent knows exactly what to do, and can the court supervise compliance without being drawn into ongoing management. Has the applicant acted promptly and with clean hands. And is the applicant willing to give the undertaking as to damages that the court requires.
A Worked Example
A logistics business trades from a leased warehouse and depends on a software platform supplied by a vendor under a written contract. On 3 March, in a dispute over a single contested invoice, the vendor switches off the business's access to the platform overnight and dispatch stops. The contract does not allow the vendor to suspend access over a disputed amount.
The business cannot wait for a trial. Every day without the platform is lost revenue and damage to its standing with its own customers, and the loss is awkward to quantify precisely. On 4 March it puts the vendor on notice demanding reconnection. The vendor refuses. On 5 March the business applies for an urgent mandatory interlocutory injunction compelling the vendor to restore access.
To succeed it must show more than an arguable case. It must give the court a high degree of assurance that the suspension was wrongful, which the clear contract terms supply, and it must show that damages are an inadequate remedy because the harm is continuing and hard to measure. It gives the undertaking as to damages. On the strength of clear terms and pressing harm, the court orders reconnection pending trial. Had the contract genuinely allowed suspension, or had the business sat on its hands for three weeks before applying, the application would likely have failed.
Common Commercial Triggers
Restoring access. Wrongful lockouts from premises, systems or platforms are the classic case for urgent mandatory relief, because the harm compounds daily and is hard to value.
Delivery up of property or documents. Where a departing employee, contractor or former partner holds property, records or confidential material they have no right to keep, a mandatory injunction can compel its return. This often runs alongside a freezing order where assets are also at risk.
Reversing a wrongful exclusion. A director or shareholder shut out of a company in breach of the constitution or a shareholders agreement may seek an order restoring access to information or to the conduct of the business, depending on the facts.
Reconnection of an essential supply. Where a supplier wrongly cuts off a service the business cannot operate without, the court can compel reconnection pending resolution of the underlying dispute.
Final Mandatory Injunctions and Damages in Lieu
At trial, once rights are decided, the court still has a discretion. Under the equitable damages power in the Civil Proceedings Act 2011 (Qld) a court that can grant an injunction may award damages instead of, or in addition to, an injunction. So even a successful party may be left to damages where compelling performance would be oppressive or out of all proportion to the benefit. A court asked to order the demolition of a structure that encroaches only slightly, at great cost and little real benefit, may decide damages are the just outcome. The same logic that makes mandatory relief cautious before trial runs through the final stage. The court will not compel action where the burden plainly outweighs the wrong.
Practical Points That Decide These Cases
Move quickly. Delay is read as a sign the harm is not truly urgent, and it weakens a mandatory application more than almost anything else.
Come with clean hands. Equity will not compel the other side to perform while the applicant is itself in breach of the same arrangement.
Make the order workable. The court must be able to state precisely what the respondent has to do. Orders that would need continuous supervision are harder to obtain.
Be ready to give the undertaking as to damages, and be honest about your capacity to meet it, because the court will ask. If the dispute is heading to a hearing, our guide to commercial court proceedings sets out what follows.
Frequently Asked Questions
What is the difference between a mandatory and a prohibitory injunction?
A prohibitory injunction orders a person to stop doing something. A mandatory injunction orders a person to do something positive, such as return property or restore access. Courts treat mandatory injunctions with more caution because compelling action carries a greater risk of injustice if the court turns out to be wrong.
Are mandatory injunctions harder to get than prohibitory ones?
Generally yes, especially before trial. For an urgent mandatory injunction the court usually looks for a high degree of assurance that the order will be seen at trial to have been rightly granted, which is a more demanding standard than the serious question to be tried test that applies to prohibitory relief.
Can I get a mandatory injunction urgently, before the case is decided?
Yes. It is called an interlocutory mandatory injunction. You need strong and clear evidence of your right and of the breach, proof that damages would not be an adequate remedy, and you must give an undertaking as to damages. Speed matters, because delay undermines the application.
Do I have to promise to pay damages to get one?
Almost always. The court requires the usual undertaking as to damages, a promise to compensate the other side if the injunction is later found to have been wrongly granted. The court will want to be satisfied you can meet it.
How Astris Law Helps
We act for business owners in urgent injunction applications across the Federal Court and the Queensland courts, on both sides of the order. Where you need to compel action, we move quickly to assemble the evidence the higher mandatory standard demands. Where an injunction has been sought against you, we test whether the applicant has met that standard and whether damages were the real remedy all along. Learn more about our dispute resolution and litigation practice, or for the general procedure on urgent and interlocutory injunctions, see our guide to urgent injunctions in Australia.
Conclusion
A mandatory injunction is one of the strongest things a court can do for you. It does not just hold the line, it forces the other side to put right what they have done. That power is exactly why the courts are careful with it, and why these applications are won on the quality of the evidence and the clarity of the right rather than on volume. If someone has shut you out, cut you off or refused to return what is yours, the law can compel them to act, but the case has to be built properly and fast.
