Anti-Suit Injunctions: Competing Proceedings

What an Anti-Suit Injunction Restrains

An anti-suit injunction directs a party’s conduct, rather than instructing a foreign court how to exercise its jurisdiction. It can restrain commencing a claim, pursuing a particular application or taking further steps in identified proceedings. Its reach depends on the actual order.

Three remedies address different problems:

Remedy	What it controls	Question for the file
Anti-suit injunction	A person’s pursuit of specified proceedings	Why is that person’s conduct legally restrainable?
Stay of the Australian case	Progress of the local proceedings	Why must the Australian proceeding pause?
Freezing order	Specified dealings with assets	What threatens the availability of assets to meet a judgment?

A party seeking an Australian stay on forum non conveniens grounds asks the local court to pause its own case. An anti-suit application seeks a different intervention. A concern about money leaving an account may call for asset-preservation relief without establishing a basis to restrain litigation.

Identify the Basis for the Restraint

Identify whether the application protects a contractual right, invokes equitable protection against oppressive litigation or protects the integrity of Australian proceedings. Those bases require different reasoning. A general comparison of convenience does not replace the selected legal test.

The High Court’s CSR Ltd v Cigna Insurance Australia Ltd distinguishes equitable restraint from a court’s power to protect its own processes. The reasons in ABC v Lenah Game Meats, at paragraphs 90 to 94, explain that distinction by reference to CSR. They also identify contractual promises against foreign litigation as a possible basis for equitable relief.

For a contractual case, identify the promise, who is bound and whether the foreign claim falls within it. An exclusive jurisdiction clause and an arbitration agreement require attention to their terms, validity and applicable statutory regime. Naming a clause does not establish that it governs every party or every claim.

For protection of local proceedings, identify the particular interference with the Australian process. For equitable restraint, identify the circumstances said to make the foreign litigation oppressive or otherwise justify equitable intervention. Explain the foreign court’s role and the effect on the respondent’s ability to seek relief. Comity requires respect for that court’s exercise of jurisdiction when deciding whether to restrain the party.

Later authority also requires attention to the actual statutory basis. In Carmichael Rail Network v BBC Chartering Carriers, the High Court rejected a challenge to a London arbitration clause under the Australian Hague Rules. The relevant undertaking and declaration formed part of the circumstances assessed. That shipping decision does not create a universal test for commercial anti-suit applications.

Assemble the Competing-Proceedings Record

Compare the actual proceedings through their documents, including each party’s capacity and the relief sought. Put the originating process beside amendments, agreements, evidence and operative orders. Obtain reliable translations where needed and identify any foreign-law proposition requiring expert evidence.

A comparison schedule needs the following fields:

• Parties and capacities, including trustees, guarantors or related companies.
• Contractual provisions and the parties each provision binds.
• Claims, disputed issues and relief sought in each forum.
• Procedural stage, pending hearings and existing restraints or undertakings.
• The particular inconsistency, interference or contractual breach alleged, with its source.

Parallel proceedings can address related conduct without being an abuse. In Michael Wilson & Partners v Nicholls, the High Court rejected the abuse finding concerning the Australian proceedings. The London arbitration and Australian action involved different defendants, and the whole controversy could not be heard in one process. The case also distinguishes overlapping liability from double recovery.

Fictional Cross-Border Transfer

Assume an Australian company claims that a director misapplied a $240,000 transfer. An overseas supplier sues the company for payment under a supply contract. Both files refer to the same receiving account.

The Australian issue may concern the director’s authority and the use of company funds. The supplier’s claim may concern delivery and the contractual debt. A shared account establishes a factual connection, but the pleadings must establish the alleged overlap in issues or relief.

Reconcile the payment against the source statements and invoice. If one pleading alleges that the transfer discharged the invoice while another seeks the full invoice amount, cite both passages. Account for any refund or partial credit. Avoid describing an inconsistency until the parties’ positions and the payment’s treatment support it.

Record the urgency separately. Identify the next overseas hearing, notice given and what harm is said to occur before an Australian inter partes hearing. Attach the foreign orders or supported procedural evidence behind that account. A lawyer’s description of urgency needs the event and consequence that make delay harmful.

Frame the Application and the Response

For a NSW Supreme Court application, identify the court’s jurisdiction over the respondent and the source of the requested power. Section 66 of the Supreme Court Act 1970 provides the injunction power. Part 25 of the Uniform Civil Procedure Rules governs interim relief. These provisions do not dispense with the substantive basis for an anti-suit restraint.

The Judicial Commission’s interim injunction procedure describes a notice of motion in existing proceedings, duly served. A summons can include a separate prayer for interim relief. Support the application with affidavit evidence and proposed orders. Address service outside Australia and any required leave separately if the respondent is overseas.

For urgent relief without notice, explain why notice cannot be given and disclose material adverse matters. The applicant will usually need the undertaking as to damages under rule 25.8 and evidence of capacity to honour it. Use the court’s current duty arrangements for listing. The broader injunctions framework explains interim relief and undertakings.

The respondent must address the asserted basis directly. Possible answers concern the clause’s scope, jurisdiction over the person or absence of interference with local proceedings. Evidence can also address delay, prejudice, the foreign process and excessive restraint. Identify any overseas order that creates conflicting obligations.

Draft the restraint around an identified party, proceeding and prohibited step. A fictional proposal might restrain the company from prosecuting its specified overseas debt claim pending the return hearing. State any permitted application to preserve rights or obtain directions. Address whether communication with the foreign court is required and how that communication can occur.

Avoid a prohibition on all overseas litigation when the evidence concerns one claim. Include a return hearing or review mechanism appropriate to the interim order. The Australian restraint does not automatically adjourn or terminate the foreign case.

Verify the Order and the Permitted Conduct

Compare the entered order with the service record, undertaking and continuing directions before advising on the next foreign step. Use the entered terms, including exceptions and expiry provisions, instead of the relief originally requested.

Maintain a record of service, receipt and the steps taken by each affected person. Confirm the foreign proceeding’s status through its orders or properly supported evidence. An Australian order directed to a party does not establish what the foreign court has done.

If the terms leave a necessary step uncertain, seek clarification or variation before taking it. Preserve the correspondence, filings and hearing record behind any alleged breach. Whether conduct amounts to contempt of court requires a separate legal and procedural assessment.

For each pending act, record whether the order permits it, restrains it or requires an application for changed directions. Give the foreign legal team the entered order and the instructions needed to manage the foreign case within those terms.
