Kotoye v. C.B.N. (1989) 1 NWLR (Pt. 98) 419: Nnaemeka Agu, JSC stated the distinction between “ex parte” & “injunction”: I think it is correct to say that “ex-parte” in relation to injunctions is properly used in contradistinction to, “on notice” – and both expressions, which are mutually exclusive, more strictly rather refer to the manner in which the application is brought and the order procured. An applicant for a non-permanent injunction may bring the application ex-parte, that is without notice to the other side or with notice to the other side, as is appropriate. By their very nature, injunctions granted on ex-parte applications can only be properly interim in nature. They are made, without notice to the other side, to keep matters in status quo to a named date, usually not more than a few days, or until the respondent can be put on notice. The rationale of an order made on such an application is that delay to be caused by proceeding in the ordinary way by putting the other side on notice would or might cause such an irretrievable or serious mischief. Such injunctions are for cases of real urgency. The emphasis is on “real.”
EX PARTE INJUNCTIONS ARE FOR CASES OF REAL URGENCY
Megarry, J., as he then was, put the principle rather succinctly in the case of Bates v. Lord Hailsham of Marylebone (1972) 3 All ER. 1019 at p.1025 where he stated: An injunction is a serious matter, and must be treated seriously. If there is a plaintiff who has known about a proposal for ten weeks in general terms and for nearly four weeks in detail, and he wants an injunction to prevent effect being given to it at a meeting of which he has known for well over a fortnight, he must have a most cogent explanation if he is to obtain his injunction on an ex-parte application made two and a half hours before the meeting is due to begin. It is no answer to say, as counsel for the plaintiff sought to say, that the grant of an injunction will do the defendants no harm, for apart from other considerations, an inference from an insufficiently explained tardiness in the application is that the urgency and the gravity of the plaintiffs case are less than compelling. Ex-parte injunctions are for cases of real urgency, where there has been a true impossibility of giving notice of motion.
