In NNPC v. FAMFA OIL LTD. (2012) 17 N.W.L.R. (Part 1328) S.C. 148, this Court, while faced with a similar objection to the grounds of appeal, went ahead to deal extensively with the criteria for identifying when a ground of appeal is one of law, of fact, or of mixed fact and law. Rhodes-Vivours J.S.C., at Pp. 175 – 176, Paragraphs C – H, as follows: “…. In Nwadike v. Ibekwe (Supra), this Court explained further that: (a) It is an error in law if the adjudicating Tribunal took into account some wrong criteria in reaching its conclusion. (b) Several issues that can be raised on legal interpretation of deeds, documents, terms of arts and inference drawn there from are grounds of law. (c) Where a ground deals merely with a matter of inference, even if it be inference of fact, a ground framed from such is a ground of law. (d) Where a tribunal states the law in point wrongly, it commits an error in law. (e) Where the complaint is that there was no evidence or no admissible evidence upon which a finding or decision was based, same is regarded as a ground of law. (f) If a Judge considers matters which are not before him and relies on them for the exercise of his discretion, he will be exercising same on wrong principles and this will be a question of law…..”
WHERE PARTICULARS NOT IN SUPPORT OF GROUND, GROUND IS INCOMPETENT
Access Bank Plc v Sijuwade (2016) LPELR 40188 (CA) per Danjuma JCA: “… the sum total of all legal principles and judicial precedents on the relationship between ground of appeal and supporting particulars is that on reading a ground of appeal and its particulars, the adverse party must be left in no doubt as to what the complaint of the appellant is. In other words, a ground of appeal and its particulars go together. Where the particulars in support of ground are not related to the ground, the ground is incompetent. See Hambe v Hueze (2001) 2 SC 26.”
