EXPLANATION / SCOPE

An undertaking as to damages is required for every interlocutory injunction. It is the price of obtaining the injunction. The rule applies even if the plaintiff acted in good faith. The undertaking protects the defendant if the injunction is later discharged. The principle is settled law. The court must extract the undertaking before granting the injunction. The failure to extract may be cured on appeal. The rule applies to both ex parte and inter partes injunctions. The undertaking is a condition for the injunction. The court may enforce the undertaking.
