There are two options open to this court. 1. to remit the case to the trial court to be heard de novo by another judge, or 2. for this court to put itself in the shoes of the trial court and do what that court ought to have done after hearing arguments on the admissibility of both letters. It would be wrong to make an order of retrial if such an order would give the party that lost an opportunity a second time to prove what he failed to prove. A retrial should not be made where the plaintiff fails to prove his case and there is no substantial irregularity apparent on the record. See Thompson v. Arowolo (2003) 7 NWLR Pt.818 P.163 Solomon v. Magaji (1982) 11 SC. P.1. Wassah & Ors. v. Kara & Ors. (2014) – SC.309/2001
ASSESSMENT OF WITNESS IS WITHIN THE PROVINCE OF THE TRIAL COURT
In the case of Afolalu v. The State (2012) vol. 10 LRCNCC 30 at 40, ratio 13; (2010) 16 NWLR (Pt. 1220) 584, when this court held, inter alia, that: “The assessment of credibility of a witness is a matter within the province of the trial court as it is the only court that has the advantage of seeing, watching and observing the witness in the witness box. The court also has the liberty and privilege of believing him and accepting his evidence in preference to the evidence adduced by the defence. On the issue of credibility of witnesses, the appraisal of evidence and the confidence to be reposed in the testimony of any witness, an appellate court cannot on printed evidence usurp the essential function of the trial court which saw, heard and watched the witnesses testify.”
