Ratio Decidendi

Per Adekeye, JSC, in Opobiyi & Anor v. Muniru (2011) NLC-123-30-2005(SC) at pp. 8—9; Paras E—A:

"Locus standi is the legal capacity to institute an action in a court of law. Where a plaintiff is held to lack the locus standi to maintain an action, the finding goes to the issue of jurisdiction - as it denies the court jurisdiction to determine the action. Jurisdiction is in other words, a radical question of competence - a court can only be competent when the case comes by due process of law and upon fulfillment of any condition precedent to the exercise of jurisdiction."
