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
WHERE ORAL EVIDENCE IN PRIOR TRIAL MAY BE USED
Ariku v. Ajiwogbo (1962) All NLR (Pt. 4) 630, Ademola CJF (of blessed memory) delivering the judgment of the Supreme Court stated the law as follows:- “This court has frequently directed attention to the practice, now not uncommon of making use of evidence of a witness in another case as if it were evidence in the case on trial. As was pointed out in Alade v. Aborishade (1960) 5 FSC 167 at 171, this is only permissible under section 33 or 34 of the Evidence Act. Where a witness in a former case is giving evidence in a case in hand, his former evidence may be brought up in cross-examination to discredit him if he was lying, but evidence used for this purpose does not become evidence in the case in hand for any other purpose. There are also prerequisites to the making use of the former testimony of a witness; for example his attention must be called to the former case where such evidence was given and he would be reminded of what he had said on the occasion.”
