In INEC v. Ogbadibo LGC (2014) 22640(CA) 24-25, F-C, by Ogbuinya, JCA as follows:
“From the etymological perspective, the cliche expression, locus standi, traces its roots to Latin Language which means: “place of standing”. In its expounded legal form, locus standi denotes the legal right or capacity of a person to institute an action in a Court of law when his right is trampled upon by somebody or authority. The locus classicus on locus standi in the Nigerian jurisprudence is the case of Adesanya V The President, FRN (1981) 5 SC 112; (1981) 2 NCLR 358… Locus standi was evolved to protect the Court from being converted into a jamboree by professional litigants or meddlesome interlopers who have no interest in matters, See Taiwo V Adegboro (2011) 11 NWLR (Pt. 1159) 562″
LACK OF LOCUS STANDI ROBS COURT OF JURISDICTION; WHETHER A PERSON HAS LOCUS STANDI
Lack of locus standi on the part of the Plaintiff in a suit is a feature that robs any court of jurisdiction to entertain the suit before it. In order to have locus standito sue in an action, a Plaintiff must show, to the satisfaction of the court, that his civil rights and obligations have been or are in danger of being infringed. He must show that there is a nexus between his suit and the conduct of the Defendant(s). A Plaintiff must show sufficient connection to, and harm or potential harm or damage from the action complained of. It has been held that the tests for determining whether a person has locus to institute an action are that: (a) The action must be justiciable; and (b) There must be a dispute between the parties.
