In CHUKWUEMEKA N. OJIOGU V. LEONARD OJIOGU & ANOR (2010) LPELR – 2377 (SC), this Court per Chukwuma-Eneh JSC (of blessed memory) restated the principle inter-alia as follows:- “It is trite that an appellate Court will not allow a fresh issue on appeal to be taken without leave as it has not been pronounced upon by the Courts below. This is even more so as in this case where the appellant is trying on appeal to raise an issue which has not been raised, nor considered by the trial Court. However, where the question involves substantial point of law, substantive or procedural and it is plain that no further evidence may be called, the Court may allow the issue to be raised subject to leave having been sought and obtained.”
Counsel appeared to have worked on the misapprehension that every possible slip raises an issue. The result is that he framed too many issues -nine, for six grounds of appeal. This appears to be a reversal of the usual practice whereby one or two or more grounds raise an issue one ground can never properly raise more than one issue. It must, however, be borne in mind that an “issue” in an appeal must be a proposition of law or fact so cogent, weighty and compelling that a decision on it in favour of a party to the appeal will entitle him to the judgment of the court. This is why, apart from the fact that multiplicity of issues tends to reduce most of them to trifles, experience shows that most appeals are won on a few cogent and substantial issues, well-framed, researched and presented rather than on numerous trifling slips.
