Strip the Latin and the citations away, and the interlocutory court faces one honest predicament: it must act now, and it might be wrong. Everything in the test — from Campus Oil’s questions to Merck v Clonmel’s recalibration — is machinery for handling that predicament fairly.
The Questions on the Scales
First, the threshold: is there a fair, bona fide question to be tried — a serious issue, not a mini-trial (though orders mandatory in substance demand more: a strong case). Then the filter: would damages be an adequate remedy — if money at trial truly repairs the harm, emergency intervention isn’t needed; which is why injunction practice clusters where money fails: land taken, confidence escaped, reputation attacked, the business that won’t survive to judgment. Then the weighing itself: each side’s harm compared — what does the applicant lose if refused and later proven right, against what the respondent loses if restrained and later proven wronged — with the status quo leaning toward preservation over irreversible change, and the undertaking as to damages reassuring the scales that restraint’s cost has someone standing behind it.
The Modern Grammar: Least Risk of Injustice
The Supreme Court’s recalibration in Merck v Clonmel made the exercise honest about itself: not rigid sequential boxes but a flexible, holistic balance of justice, with damages-adequacy weighed inside the balance rather than as a mechanical knockout, the case’s strength and commercial realities admitted openly — and the ultimate question stated plainly: which course carries the least risk of injustice if trial proves it wrong? For litigants, the practical translation: applications and defences are built as persuasive wholes — specific evidence of why money fails here, of comparative harm, of what the status quo actually is — not as checklists recited. The full test page carries the complete treatment, both chairs.
One strategic corollary each way: applicants — move early, so the status quo you preserve is the one you want; respondents — never race the disputed act to completion, because the race becomes the applicant’s best evidence of exactly the injustice the scales exist to prevent.
