With due deference to the learned Senior Advocate of Nigeria, it is settled law that evidence of a witness taken in an earlier proceedings is not relevant in a later trial or proceeding except for the purpose of discrediting such a witness in cross examination and for that purpose only. – Sanusi JCA. Enejo v. Nasir (2006)
ORAL EVIDENCE INADMISSIBLE TO CONTRADICT DOCUMENT
It is trite law that oral evidence is inadmissible to contradict the contents of a document. In other words oral testimony cannot be used to state the content of a document. This is so, because documents when tendered and admitted in court are like words uttered and do speak for themselves. They are more reliable and authentic then words from the vocal cord of man as they are neither transient nor subject to distortion and miss-interpretation but remain permanent and indelible through the ages.
