It is trite law now that where a Notice of Preliminary Objection is filed and moved before a court of law, the court is duty bound to consider the Preliminary Objection before venturing into the main or cross-appeal, as the case may be. See: AGBAREH and ANOR v. MIMRA and ORS, (2008) 1 SCNJ. 409, ONYEKWULUJE v. ANIMASHAUN and ANOR [1996] 3 SCNJ 24; ONYEMEH and ORS. v. EGBUCHULAM and ORS. [1996] 4 SCNJ 235 … The aim/essence of a preliminary objection is to terminate at infancy, or as it were, to nib it at the bud, without dissipating unnecessary energies in considering an unworthy or fruitless matter in a court’s proceedings. It, in other words, forecloses hearing of the matter in order to save time, See: YARO v. AREWA CONSTRUCTION LTD. and ORS. [2007] 6 SCNJ 418.
