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)
GROUND OF APPEAL WHICH NO ISSUE HAS BEEN FORMULATED WILL BE STRUCK OUT
A ground of appeal which no issue has been formulated or has no bearing with any issue canvassed in the appeal is deemed abandoned and liable to be struck out.
— T. Akomolafe-Wilson, JCA. Onnoghen v. FRN (2019) – CA/A/44C/2019
