It is trite that by the rules of practice and procedure, in particular, of the appellate Courts, appeals are to be determined on the issues distilled from the competent grounds of appeal raised against the judgment being appealed. Therefore, any ground of appeal from which no issue has been formulated is deemed to have been abandoned and is liable to be discountenanced and struck out by the Court. Indeed, any such ground is lifeless and may not need a specific order to have it struck out yet should still be struck out. In this appeal, no issue has been formulated from grounds 4, 5, 6, 7 & 8 of the Amended Notice of Appeal. Meaning that those grounds are deemed abandoned. Accordingly, the said grounds 4, 5, 6, 7 & 8 are struck out.
