In BANK OF INDUSTRY LTD v. AWOJUGBAGBE LIGHT INDUSTRIES LTD (2018) LPELR-43812(SC), page 7 para. B-D, per Rhodes-Vivour JSC, reiterated the above principle of law thus: “This Preliminary Objection is against the hearing of this suit. In Isah v. INEC & 3 Ors (2014) 1-2 SC (Pt.iv) p.101. I explained Preliminary Objections and when to file them and when not to file them. I said that: “A Preliminary Objection should only be filed against the hearing of an appeal and not against one or more grounds of appeal which are not capable of disturbing the hearing of the appeal. The purpose of a Preliminary Objection is to convince the Court that the appeal is fundamentally defective in which case the hearing of the appeal comes to an end if found to be correct. Where a preliminary objection would not be the appropriate process to object or show to the Court the defects in processes before it, a motion on notice filed complaining about a few grounds or defects would suffice.
AFFIDAVIT SHOULD BE FILED WHERE THERE ARE ISSUES OF FACTS IN PRELIMINARY OBJECTION
Grounds (v), (vi) and (vii) of the preliminary objection themselves raise issues of facts, at best issues of mixed law and facts, for which the defendant ought to have filed a supporting affidavit. The defendant did not. Grounds (v), (vi) and (vii) are respectively stated to be thus: (v) The Plaintiffs’ Suit does not disclose a reasonable cause of action against the Defendants. (vi) The Plaintiffs’ Suit is lacking in bona fide, as it was filed to harass, irritate and embarrass the Defendant, which constitutes an abuse of judicial process. (vii) The ministers (sic) Referral offends the twin pillar of Justice – nemo judex in causa sua and audi alterem partem. These are not grounds that can be resolved without the facts upon which they are based — facts that ought to come by way of an affidavit from the defendant.
