Locus standi , which is a Latin word simply means a place of standing. It is the legal right of a party to an action to be heard in Litigation before the Court or Tribunal. The term denotes, the right of a party to institute an action in a Court of Law or seek judicial enforcement of a duty. See Senator Adesanya vs. President FRN (1981) 5 SC 112, Adesolakan Vs. Adegbo vs. A. G, Lagos State (2012) All FWLR (Pt 631) 1522. Locus standi thus, entails the legal capacity of instituting or commencing an action in a competent Court of Law without any inhibition, obstruction or hindrance from any person or body whatsoever. Whenever a person’s Locus to sue is in issue, as in this appeal, the question is really whether the person whose standing is in issue, is the proper person to request an adjudication over the dispute he has brought for adjudication. The issue at this stage, is whether the Plaintiff or the person whose locus is challenged, has disclosed sufficient interest in the dispute or the subject matter of the dispute.
