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.
AN AMENDED NOTICE OF APPEAL OBLITERATES THE EARLIER NOTICE
Ordinarily, an amended notice of appeal completely obliterates the original notice of appeal amended. It no longer avails the appellant either to formulate his issues for the determination of the appeal therefrom or to argue his appeal on the original notice amended … I agree with the 3rd Respondent that it is the law that an appellant cannot rely on and argue his appeal on more than one notice of appeal because an issue in an appeal cannot be determined on two separate filed notices of appeal. CHUKWU v. THE STATE (2007) All FWLR 1224 at 1240. It also the law that a withdrawn notice of appeal is taken as abandoned. Upon amendment of the notice of appeal upon leave of Court, the amendment goes to the roots and the amended notice of appeal, superseding the original notice of appeal, has the effect of completely obliterating the original notice of appeal which is taken to have been abandoned. Technically, it no longer avails the appellant to rely on the original notice of appeal, it having been amended and deemed abandoned.
