In Ideozu v. Ochoma (2006) 4 NWLR (Pt. 970) 364 at 395, at C-E Per Tobi, JSC held thus: “In Ajewole v. Adetimo (1996) 2 NWLR (Pt. 431) 391, this Court held that when a Court is asked to restrain a party from doing an act pending the decision in a matter before it, but the act has been done, no order to restrain will be made. This is so because, what is sought to be prevented had happened. In other words, an interlocutory injunction is not a remedy for an act, which has already been carried out.”
GRANT OF INTERLOCUTORY INJUNCTION DISCRETIONARY
It is quite clear from these statutory provisions that the grant of an application for interlocutory injunction is purely discretionary though the Court is enjoined to consider in the exercise of its discretion whether the grant of the discretion will be just or convenient. In other words for the exercise of the discretion to be judicial, it is sine qua non that the grant of the application should be either just or convenient.
