Onubogu and Anor v. The State (1974) 9 S.C. 1, 20: the Supreme Court opined that where in a criminal case, one witness called by the prosecution’ contradicts another prosecution witness on a material point, the prosecution ought to lay some foundation, such as showing that a witness was hostile, before they can ask the court to reject the testimony of one witness in preference for the evidence of the discredited witness. It is not competent for the prosecution to discredit one and accredit the other.
COURT CAN PREFER ONE EXPERT WITNESS TO ANOTHER
It is trite law that where there is conflict in the opinions of experts, it is the duty of the court to come to a conclusion in the case by resolving such a conflict and can do so by rejecting the opinion of one or the other such experts. See John Wilberforce Bamiro v. S.C.O.A. (1941) 7 WACA 150; R v. Godo (1975), 61 Cr App R.131; Ozigbo v. Police (1976) 1 NMLR 273, Laws and Practice Relating to Evidence in Nigeria by Aguda at p.115 Article 9-05.
