Interlocutory Injunctions in Commercial Disputes: The Balance of Convenience Test in Victoria

When a commercial dispute escalates in Victoria, businesses often need urgent court intervention to prevent immediate harm. If you are a company director, shareholder, or commercial party dealing with misuse of confidential information, breach of contract, or the risk of asset dissipation, understanding how to get an interlocutory injunction in Australia in a commercial context is critical. The central issue the court will assess is the interlocutory injunction balance of convenience Victoria test, which determines whether interim relief should be granted before a final hearing. 

To succeed, an applicant must show there is a serious question to be tried and that the balance of convenience favours granting the injunction. This includes addressing practical risks, commercial consequences, and the requirement to provide an undertaking as to damages. In high-stakes matters, including claims involving misuse of confidential information or the need for a springboard injunction, early strategic decisions can determine whether your position is preserved or irreparably compromised. 

This article explains how interlocutory injunctions operate in Victorian commercial litigation, with a focus on the balance of convenience test and the strategic considerations that influence whether urgent relief is granted. 

What Is the Legal Test for an Interlocutory Injunction in Victoria? 

In Victoria, interlocutory injunctions are granted under the court’s equitable jurisdiction, supported by procedural rules such as the Supreme Court (General Civil Procedure) Rules 2015 (Vic). These rules allow the court to grant urgent interim relief where necessary to preserve rights and prevent harm before a final hearing. 

The governing legal framework is derived from American Cyanamid Co v Ethicon Ltd [1975] AC 396 and adopted in Australia by the High Court in Australian Broadcasting Corp v O’Neill (2006) 227 CLR 57. Together, these cases establish the two-stage test applied by courts when determining whether to grant an interlocutory injunction. 

The first requirement is that there must be a serious question to be tried. This does not require proving that the claim will succeed. Instead, the court considers whether the claim is arguable and supported by sufficient evidence. In commercial disputes, this commonly arises in matters involving breach of contract, misuse of confidential information, or contraventions of statutory obligations. 

The second and more decisive stage is the interlocutory injunction balance of convenience Victoria test. At this stage, the court evaluates the practical consequences of granting or refusing the injunction. The central question is which course carries the lower risk of injustice. This involves assessing whether damages would be an adequate remedy, the likelihood of irreparable harm, and the respective prejudice each party would suffer. 

A key safeguard in this process is the undertaking as to damages. An applicant must give a binding promise to compensate the respondent if it is later determined that the injunction should not have been granted. Courts place significant weight on this undertaking, particularly in high-value commercial disputes where the financial consequences of an injunction can be substantial. 

In some cases, courts may grant more targeted relief, such as a springboard injunction, which prevents a party from benefiting from an unfair commercial advantage obtained through prior misconduct. 

How Do Victorian Courts Apply the Balance of Convenience Test in Practice? 

What evidence do courts require to establish urgency and risk? 

Victorian courts require clear, admissible evidence showing why urgent interim relief is necessary. This is typically provided through affidavit material outlining the factual background, the alleged wrongdoing, and the immediate risk of harm. In commercial disputes, this may include contracts, correspondence, or evidence of misuse of confidential information. 

While the court does not determine the case in full, the applicant must still demonstrate a serious question to be tried. Assertions without supporting evidence are insufficient. The more precise and credible the evidence, the more likely the court will intervene. 

How do courts assess the balance of convenience? 

The interlocutory injunction balance of convenience Victoria test focuses on which outcome carries the lower risk of injustice. Courts weigh the consequences of granting or refusing relief by considering: 

• whether damages are an adequate remedy  

• the nature and extent of harm before trial  

• the need to preserve the status quo  

In commercial matters, courts are more inclined to grant relief where harm is irreversible or difficult to quantify, such as loss of confidential information or competitive advantage. The analysis is practical and outcome driven. 

Why is the undertaking as to damages critical? 

The undertaking as to damages is a key condition of relief. The applicant must compensate the respondent if the injunction is later found to have been wrongly granted. 

Courts place significant weight on this undertaking when applying the balance of convenience test. An applicant with the financial capacity to honour it is in a stronger position. If capacity is uncertain, the court may refuse relief or impose conditions. This is particularly relevant in high-value commercial disputes. 

When will a court refuse to grant relief? 

Courts will refuse an interlocutory injunction where the legal or discretionary thresholds are not met. Common reasons include: 

• failure to establish a serious question to be tried  

• delay undermining urgency  

• damages being an adequate remedy  

• disproportionate prejudice to the respondent  

Delay is especially damaging. If an applicant does not act promptly, the court may conclude that urgent intervention is not justified. 

When are springboard injunctions used? 

A springboard injunction may be granted where a party has gained an unfair commercial advantage through prior misconduct. This type of order prevents the respondent from benefiting from that advantage, even if the initial wrongdoing has stopped. 

In practice, this ensures that the balance of convenience produces a commercially fair outcome, particularly in disputes involving confidential information or competitive positioning. 

In What Commercial Disputes Are Interlocutory Injunctions Most Commonly Used? 

In Victorian commercial litigation, interlocutory injunctions are most often deployed where time-sensitive harm cannot be undone. These applications arise in high-pressure situations where businesses must act immediately to protect commercial value, confidential information, or market position. 

One of the most common scenarios involves breach of confidence and misuse of confidential information. This frequently occurs when a former employee, contractor, or business partner departs with sensitive data such as client lists, pricing models, or proprietary processes. In these cases, applicants often seek urgent interim relief to restrain use or disclosure, sometimes alongside a springboard injunction to neutralise any unfair competitive advantage already gained. 

Another recurring category is restraint of trade and employment disputes. Businesses regularly apply for interlocutory injunctions to enforce non-compete or non-solicitation clauses. The commercial risk is immediate. Once clients are approached or key staff are poached, the damage is hard to reverse. Courts therefore focus closely on whether the restraint is enforceable and whether the interlocutory injunction balance of convenience Victoria test favours preserving the status quo. 

Interlocutory relief is also critical in shareholder and partnership disputes, particularly where there is a breakdown in relationships within closely held entities. In these matters, injunctions may be sought to restrain directors from dealing with company assets, accessing bank accounts, or making unilateral decisions that prejudice other stakeholders. In these cases, businesses may need urgent court intervention to restrain conduct and preserve assets, as seen in shareholder injunction applications. 

In more serious cases, businesses seek injunctions to prevent asset dissipation or diversion of funds, particularly where there are concerns about insolvency or misconduct. While freezing orders are a distinct remedy, interlocutory injunctions often operate alongside them as part of a broader litigation strategy. 

From a practical perspective, these disputes are defined by speed, evidence, and precision. Courts expect applicants to act immediately, present clear evidence, and demonstrate why damages are insufficient. Delay, weak evidence, or overreaching claims can quickly undermine an otherwise strong position. In practice, the difference between success and refusal often lies in how effectively the application is prepared and framed at the outset. 

What Should You Consider Before Applying for an Interlocutory Injunction in Victoria? 

Interlocutory injunctions are powerful but demanding remedies. Success depends as much on strategy and preparation as it does on satisfying the legal test. Before starting an application, parties should assess whether the evidence and timing support urgent interim relief. 

The priority is speed with substance. Courts expect applicants to act immediately once a risk emerges. Any delay can undermine claims of urgency and weaken the interlocutory injunction balance of convenience Victoria argument. However, urgency alone is not enough. The application must be supported by precise, well-prepared affidavit evidence that clearly establishes a serious question to be tried and the nature of the harm. 

Equally important is the undertaking as to damages. Applicants must be prepared to stand behind this commitment, both legally and financially. In high-value disputes, courts will scrutinise whether the applicant has the capacity to compensate the respondent if the injunction is later found to be unjustified. This can materially affect whether relief is granted. 

From a defensive perspective, respondents should focus on challenging the balance of convenience. This includes demonstrating that damages are an adequate remedy, that the alleged harm is overstated, or that the injunction would cause disproportionate commercial prejudice. Evidence of delay, weak contractual foundations, or overbroad claims can be decisive. 

Interlocutory injunction applications are won or lost on precision, credibility, and timing. A well-structured approach that anticipates both legal and commercial consequences is essential to achieving a favourable outcome.
