All superior Australian courts have a wide power and discretion to grant both interlocutory orders and interlocutory injunctions. An interlocutory application, generally speaking, is an application which seeks any order other than a final judgment.
As in other jurisdictions, interlocutory injunctions are a species of interlocutory orders. Where those orders are sought on an urgent and temporary basis until a more extended form of relief is sought, they are often referred to as interim orders.
Interlocutory orders (including interlocutory injunctions) can require a party to undertake or refrain from a particular act, and can be granted before proceedings have commenced, once they are on foot and after judgment has been entered. Applications for these types of orders may be made by self-represented litigants or through legal representation.
The categories of non-urgent interlocutory orders that an applicant may seek are many and varied and include, by way of example, applications for security for costs, discovery (including preliminary discovery before proceedings have been commenced), the filing of expert evidence or orders for particulars, The evidence required to obtain non-urgent interlocutory orders will turn on the type of orders sought, although at the very least substantive interlocutory applications usually require a sworn affidavit to be filed.
The kinds of relief that can be sought by way of an urgent interlocutory injunction are equally varied. This is because the orders have the purpose of preserving the status quo until the rights of the parties can be determined finally, and the types of matters that can be heard by the court are vast. Common urgent interlocutory injunctions include applications for the preservation of property, the freezing of assets and applications to search premises to preserve evidence.
An applicant for an interlocutory injunction (either urgent or not) must prove that:
- there is a serious question of law to be tried;
- the balance of convenience favors the granting of the injunction; and
- an award of damages (at the conclusion of the proceeding) would not be an adequate remedy.
It is possible for urgent interlocutory injunction applications to be heard by the court ex parte, without the opposing party’s involvement. Any orders given ex parte will generally operate only for a limited period of time until the matter can be brought to a hearing. The duration of any ex parte order will ordinarily be limited to a period terminating on the return date of the summons, which should be as early as practicable (usually not more than a day or two) after the order was made, when the respondent will have the opportunity to be heard. For this reason appeals of ex parte interlocutory injunctions are not usually made to a superior court. The applicant will then bear the onus of satisfying the court that the order should be continued or renewed. A party seeking an interlocutory injunction will ordinarily be obliged to give an undertaking to pay any damages by the defendant suffered as a result of the injunction in the event that the claim for final relief at trial fails.
The decision to grant an interlocutory injunction can be appealed on an urgent basis to a relevant appeal court. The appeal court will usually list the matter before a single judge to assess the urgency (often the same or the day following the day on which the appeal is lodged) and set a timetable based on the information provided at that first listing.
