Samuel Osigwe v. PSPLS Management Consortium Ltd & Ors. (2009) 3 NWLR 378 SC: “Breach of a rule of practice and procedure does not render the proceedings a nullity but merely an irregularity.”
MUST USE OF A PARTICULAR COMMENCEMENT PROCEDURE
This is an out-flow of the elementary principle of law that where a specific procedure is provided for commencing an action, a party seeking to use the procedure must bring his case within those covered by that procedure otherwise his action will be incompetent.
