Bello, JSC, in AJIDE v. KELANI (1985) 3 NWLR (pt.12) 248 at 200 – 261, (1985) 16 NSCC (pt.2) 1298 at 1309, stated the options thus – “He may cross-examine the witness on the writing and if he is satisfied with the answer given by the witness or if he does not intend to pursue the matter further, he is not required to show the writing to the witness or to prove the writing. But if the cross-examiner intends to contradict the witness by the writing, then he must show the writing to witness and call his attention to those part of the writing which are to be used for the purpose of contradicting the witness. It is only after this condition has been complied with that the writing can be admitted in evidence.”
WHETHER OR NOT A WITNESS IS AN ACCOMPLICE IS ONE OF LAW
The question whether or not a witness is an accomplice is one of law not of fact and if, as here, the learned trial Judge erred in regarding P.W.(18) as an accomplice (to the crime of conspiracy) it is certainly open to an appellate court (and in this instance, the Federal Court of Appeal) to reverse the erroneous view of the learned trial Judge.
