An order of injunction should neither be vague nor uncertain. It should be clear and precise and it should inform the defendants what the opinion of the court is as to the limits of their rights and/or privileges in and over the land in dispute. The order should not, as in this case, be such as to expose the defendants/appellants to the consequences of violating a vague and imprecise injunction: Cother v. Midland Railway Co. 41 E.R. Ch. 1025; Karama and ano. v. Aselemi and ors. 4 W.A.C.A. 150. Chief Onyeama for the Plaintiffs/Respondents rightly conceded that the injunction granted in this case was vague and that it will thus be difficult to enforce.
