Ordinarily, any issue formulated from an incompetent ground of appeal is itself incompetent and must be struck out. Issues are the important questions formulated for determination by the court and could be distilled from more than one ground of appeal. See; Sunday Madagwa V. The State (1988) 12 SC (Pt. 1) 68 at 76 … Generally, issues are not meant to be formulated on each ground of appeal but raised or distilled out of a combination of the essential complaints of the appellant in the grounds of appeal. Therefore, issues must necessarily relate to facts or law decided by the court whose decision is appealed against. In other words, it is ideal to distill or formulate an issue from more than one ground of appeal but where this is not done or it is impossible, just only one issue may be raised from one ground of appeal. Therefore, a valid Notice of Appeal with one ground of appeal and a single issue for determination is sufficient to sustain an appeal … There is no doubt that it is now an established practice that an appeal is decided upon the issues raised or formulated for determination of the court. In effect, when issues for determination are formulated, the grounds of appeal upon which they are based or from which the issues are formulated become extinguished or expired. The argument of the appeal is then based on the issues so formulated but not on the grounds.
