Equitable relief: specific performance, injunctions and declarations 

Equitable relief is selected for the work it does, not because a claimant prefers a more dramatic remedy than damages. The central question is whether money is an adequate response to the wrong. Even when it is not, equitable remedies are discretionary: the court applies settled principles and considers the practical effect of the order.

Specific performance compels performance

Specific performance orders a party to perform a contractual obligation. It is most plausible where the promised subject matter cannot readily be replaced by money, such as unique land or a genuinely irreplaceable asset. It is less likely where market substitution makes damages adequate.

The court also asks whether the obligation is sufficiently certain and whether the order can sensibly be carried out. It will be slow to compel personal services or an arrangement requiring constant judicial supervision. Delay, hardship, the claimant’s own conduct, and harm to third parties can also matter. The analysis is not “is there a contract?” but “would this order be a just and workable response to this breach?”

The remedy must also correspond to the obligation. An order compelling a seller to transfer identified land is different from an order requiring two parties to maintain a continuing commercial relationship. In the first example, the order may be precise and readily enforceable; in the second, damages, termination, or a more limited injunction may be more realistic. The claimant should explain the practical gap left by damages rather than relying on a formula about uniqueness.

Injunctions restrain or require conduct

An injunction may be prohibitory, restraining conduct, or mandatory, requiring positive action. It may be final, after the rights have been decided, or interlocutory, preserving the position until trial. Mandatory and interim orders can require particular caution because they may effectively determine the dispute before a final hearing.

For an interlocutory injunction, the applicant must show a serious question to be tried and that the balance of convenience supports relief. The strength of the claim and the balance of convenience are not watertight compartments: a weaker claim needs a stronger practical case for preserving the position, and vice versa. Australian Broadcasting Corporation v O’Neill confirms this contextual approach.¹

Practical harm matters. A court considers whether damages would adequately compensate either party if the order is wrongly granted or refused, whether the status quo should be preserved, and any public or third-party consequences. An applicant will usually give an undertaking as to damages: a real promise to compensate loss caused by an interim order if it later proves unjustified.

The procedural stage therefore changes what an answer must establish. Before trial, the court is not finally deciding every disputed fact; it is deciding whether an order should operate while the dispute is determined. At trial, the court can decide the parties’ rights and consider final relief on a full evidentiary record. Always say whether the requested injunction is interlocutory or final before applying the test.

Declarations clarify legal rights

A declaration states the parties’ legal rights or obligations. It does not itself compel payment or conduct, but can resolve a live controversy and guide what follows. A declaration is useful where the parties need an authoritative answer before deciding whether coercive relief is necessary. It is not an advisory opinion: there must be a real dispute and a useful purpose in making the declaration.

Frame the order with precision

The proposed order matters as much as the remedy label. An injunction must tell the respondent what conduct is restrained or required with workable precision; a vague command to “comply with the law” is unlikely to assist. A mandatory order should identify the act required, any time for compliance, and whether supervision would be needed. A declaration should state the legal issue resolved, rather than narrate the parties’ whole dispute.

This is why the evidence and procedural setting cannot be separated from the merits. Urgent interim relief often depends on affidavits about practical harm, the undertaking as to damages, and the orders needed before a trial. A final hearing permits a fuller evaluation of facts and discretionary bars. The same substantive right can therefore justify different relief at different stages.

Precision also protects both parties. A respondent must be able to tell what conduct is prohibited or required, while the court must be able to determine whether the order has been obeyed. If the proposed order would operate on someone who is not a party, interfere with a third party’s rights, or leave an important practical step unspecified, that should be addressed as part of the discretionary analysis rather than left to enforcement.

Applying this in a problem question

1. Identify the right, breach or threatened conduct and the particular order sought.
2. Explain why damages do or do not adequately respond to the practical harm.
3. For specific performance, address certainty, supervision and the suitability of compelling performance.
4. For an injunction, state whether it is prohibitory or mandatory, interlocutory or final; for interlocutory relief, apply the serious-question and balance-of-convenience inquiry.
5. Work through hardship, delay, clean hands, third-party effects, the undertaking as to damages and the precision of the proposed order.

Where the authority sits

Equitable principles are developed through case law, supplemented by jurisdiction-specific statutory powers and court rules. Check the relevant court’s procedural rules before stating how an urgent application, affidavit, undertaking or final order must be made.
