Okonofua & Anor v. The State (1981) 6-7 SC 1 at 18 where this court per Bello, J.S.C., as he then was, dealing with the same subject put the matter thus:- “The correct state of the law relating to the duty of the prosecution to call witnesses, whether their names appear on the back of the information or not, has been recently stated by this court in these terms: ‘The law imposes no obligation on the prosecution to call a host of witnesses. All the prosecution need do is to call enough material witnesses in order to prove its case; and in so doing, it has a discretion in the matter.’ ” See also Samuel Adaje v. The State (1979) 6-9 SC 18 at 28.
WITNESS DEPOSITION MUST BE FILED WHETHER WITNESS IS SUBPOENAED OR NOT IN AN ELECTION PETITION
From the foregoing judicial decisions, it is clear that in election petition litigation, whether the witnesses which a party intends to call are ordinary or expert witnesses and whether they are willing or subpoenaed witnesses, their witness depositions must be filed along with petition before such witnesses will be competent to testify before the tribunal or court.
