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…..”
ISSUE MUST ARISE FROM GROUNDS OF APPEAL
It suffices to state, firstly, that an appellate court can only hear and decide on issues raised on the grounds of appeal filed before it and an issue not covered by any ground of appeal is incompetent and will be struck out. – Iguh, JSC. Oshatoba v. Olujitan (2000)
