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″
The term locus standi is a Latin term which translates to “place to stand”. It refers to the legal right of a person, natural or artificial, to file a suit. It is sometimes used interchangeably with terms like “standing”, “standing to sue” and “title to sue”. Unquestionably, the issue of locus standi is a threshold issue, and in order for a court to have jurisdiction, the Plaintiff must have locus standi to commence or file the action. Put differently, if a Plaintiff lacks the legal right to institute an action, no court will in turn have the power or competence or jurisdiction to entertain the suit. A Plaintiff’s locus Page 20 of 41 standi is inextricably linked with the jurisdiction of the court as once a Plaintiff lacks locus, the court is also bereft of jurisdiction. See AKANDE V. JEGEDE (2022) 14 NWLR (PT. 1849) 125; AJAYI V. ADEBIYI (2012) 11 NWLR (PT. 1310) 137; B.M.LTD. V. WOERMANN-LINE (2009) 13 NWLR (PT. 1157) 149.
