What is an injunction?
Explanation. An injunction is a judicial order — prohibitory (restraining an act) or mandatory (compelling an act) — aimed at preventing or remedying an ongoing or threatened wrong, rather than merely compensating past loss.
What is the distinction between a 'prohibitory' and a 'mandatory' injunction?
Explanation. A prohibitory injunction restrains the defendant from doing (or continuing to do) something; a mandatory injunction compels the defendant to take positive action, such as removing an obstruction.
A builder keeps dumping debris on Nirmala's plot. After a full trial, the court orders him to stop for good. This is:
Explanation. A prohibitory injunction forbids a continuing or repeated wrong. A perpetual injunction is granted at the end of the trial. The court may also award damages.
In American Cyanamid Co v Ethicon Ltd (1975), what was the first stage of Lord Diplock's test for granting an interim injunction?
Explanation. The first stage of the American Cyanamid test asks only whether there is a serious question to be tried — the court does not, at this stage, assess the relative strength of the parties' cases in detail.
What test did American Cyanamid replace, and why?
Explanation. Before American Cyanamid, courts required a strong prima facie case; Lord Diplock held this was inappropriate at the interim stage, since it required resolving complex disputes without a full trial — replaced by the serious-question/balance-of-convenience approach.
After finding a serious question to be tried, what does the court weigh in the second stage of the American Cyanamid test?
Explanation. The second stage weighs the balance of convenience — assessing which party would suffer greater harm from a wrong decision on the injunction, and whether damages would adequately compensate either side.
What is a 'perpetual' (permanent) injunction, and when is it typically granted?
Explanation. A perpetual (permanent) injunction is granted at the final stage of a suit, after full trial, permanently restraining the defendant based on a conclusive determination of the plaintiff's rights.
What is the key difference between an 'interim/interlocutory' injunction and a 'permanent' injunction?
Explanation. An interim injunction is a temporary, provisional measure granted pending trial on a lower threshold; a permanent injunction is granted only after full trial, finally determining the parties' substantive rights.
In a patent infringement dispute over surgical sutures, the plaintiff seeks to stop the defendant's competing product from being sold before the full trial concludes. Applying American Cyanamid, what should the court primarily assess?
Explanation. Following American Cyanamid, the court first checks for a serious question to be tried (not resolving the merits fully), then decides based on the balance of convenience between the parties.
Why might a court refuse an interim injunction even where a serious question to be tried exists?
Explanation. Passing the 'serious question' threshold is only the first stage — the court can still refuse the injunction if the balance of convenience, weighing relative harm and the adequacy of damages, favours the defendant.
