Tukur Vs Government of Gongola State (1988) 1 NSCC 30 at 36: It is more correct to say that the Rules of the Court of Appeal did not expressly provide for the filing of more than one notice. The Rules were silent on the Issue and it is therefore my opinion that every notice of appeal filed within time is valid. If more than one notices are filed within time, the others may be superfluous but not invalid. All the notices combined have been in exercise of a right of appeal. They may have stated different grounds which if permissible in law, gives validity and competency to the notice. Where several notices of appeal have been validly filed, I cannot see anything preventing an application for leave to consolidate them into one or for withdrawal of all except one.
A COMPETENT NOTICE OF APPEAL
A competent notice of appeal is like having the right key for a particular door. The notice of appeal is the key to the door to this Court. Without the right key, any effort to gain entrance through the door is an exercise in futility. It is void and therefore a nullity. In the immortal words of Lord Denning, MR in McFoy vs UAC (1961) 3 ALL ER 169 @ 172: “If an act is void, then it is in law, a nullity. It is not only bad but incurably bad … And every proceeding which is founded on it is also bad and incurably bad. You cannot put something on nothing and expect it to stay there. It will collapse.” See also: Madukolu Vs Nkemdilim (1962) 2 SCNLR 341; Skenconsult Vs Ukey (1981) 1 SC 6.
