An injunction is fundamentally a discretionary equitable remedy issued by a court to compel or restrain a party's conduct. Unlike damages (which compensate in money), injunctions directly control future behaviour—they are preventive rather than compensative. In Indian law, the statutory framework derives primarily from the procedural law governing civil suits, which recognises that some harms cannot be adequately remedied by monetary compensation alone. When a factory pollutes a neighbour's land, money damages may not undo the ongoing injury; the court must order the factory to stop. This discretionary character is crucial: the court weighs multiple factors, not merely the legal right of the claimant. Injunctions operate in two temporal phases, each with distinct procedural and substantive requirements. A temporary injunction (also called interlocutory) is granted during the pendency of litigation—before trial concludes—to maintain the status quo and prevent irreparable harm while the court investigates the merits. The applicant must demonstrate three critical elements working together: first, a prima facie case (the claimant has raised a plausible legal claim that deserves full hearing); second, that the balance of convenience favours granting the injunction (the harm to the claimant if denied exceeds the harm to the defendant if granted); and third, that damages alone are an inadequate remedy (irreparable harm would result). These are not tick-boxes—they interact. A weak prima facie case might be overcome if the balance of convenience is overwhelmingly in the applicant's favour. A strong case might fail if damages can adequately compensate. The court must also satisfy itself that the claimant comes with clean hands (has not themselves acted wrongfully) and is not seeking the injunction for an improper collateral purpose. A permanent injunction follows full trial on the merits. Here, the claimant has proven their right at trial, and the court orders the defendant to cease the wrongful conduct permanently or refrain from it in future. The temporal urgency recedes; the focus shifts to whether the proven wrong warrants ongoing restraint. The court may grant a perpetual injunction (lasting indefinitely) or a limited one (for a defined period or on specified conditions). Defences available to the defendant include laches (unreasonable delay in seeking relief, which suggests the harm is not truly urgent), acquiescence (acceptance or permission of the conduct by the claimant), and public interest (where the injunction would harm the broader community more than it protects the claimant). The court retains discretion to award damages in lieu of an injunction where the hardship to the defendant is disproportionate or where the wrong is trivial. Remedies for breach of an injunction include contempt of court proceedings, leading to criminal penalties (fine or imprisonment), making injunctions a form of order backed by coercive power. Injunctions sit at the intersection of substantive rights and procedural remedies. They presuppose that a legal right exists (property, contract, tort, intellectual property, matrimonial) but recognise that the remedy of compensation is insufficient. This distinguishes them from damages claims and also from declarations (which merely state the court's opinion on legal status without commanding conduct). Injunctions are closely related to the equitable principle that a court of equity will not grant relief where it is inequitable to do so—they embody flexibility and fairness over rigid rules. In neighbouring procedural domains, injunctions interact with concepts like stay of proceedings (which halt litigation itself, not the underlying conduct) and specific performance of contracts (which compels affirmative acts rather than restraint, though both are equitable remedies rooted in adequacy of damages). The theoretical foundation is that equity follows the law but tempers it with conscience; where law grants a right but remedy fails, equity steps in. CLAT examiners frequently distort this principle in five recurring ways. First, they present fact patterns where all three elements of a temporary injunction appear satisfied, then slip in a hidden fourth requirement (such as a procedural defect in filing or a temporal bar like limitation) and ask whether the injunction should be granted—testing whether candidates mindlessly apply the three-element test without checking legal prerequisites. Second, they reverse roles by making the defendant the one seeking an injunction (e.g., a defendant seeks an injunction to prevent the plaintiff from enforcing a judgment pending appeal) and test whether candidates recognise that the same three-element standard applies regardless of who seeks relief. Third, they conflate injunctions with specific performance by presenting a contract case and asking whether an injunction or specific performance should issue—the distinction turns on whether the remedy orders cessation of wrong (injunction) or compels affirmative performance (specific performance), and both are discretionary. Fourth, they include a subtle element of waiver or estoppel in the facts and test whether candidates spot that the claimant's prior conduct may bar relief even if legal elements are met. Fifth, they import criminal law concepts (like mens rea or criminal intent) into the civil injunction framework, where the focus is harm and remedy, not culpability—a negligent act can warrant an injunction just as readily as an intentional one.
