DR MUHAMMAD IBRAHIM ONUJABE & ORS V FATIMA IDRIS (2011) LPELR – 4059 (CA) as follows: “The Oaths act is a general statute that deals with oaths. The provision under Evidence Act on affidavit places a condition precedent which ought to be fulfilled to render the affidavit competent. One fundamental condition is the swearing on oath before the commissioner for oath. It is on this vein that the provision under the oaths Act becomes relevant. That is why a defect as regards the swearing on oath is not a mere irregularity as to form but defect as to substance.”
DEPOSITIONS WILL BE REJECTED WHERE NO COMPLIANCE WITH THE EVIDENCE ACT
While some of the depositions accord with the provisions of section 86 of the Evidence Act, the above samples do not. I must say that there are quite a large number of such like depositions. I merely took the above as sample analysis. It is my view that the depositions which complied with section 86 of the Evidence Act cannot save the entire depositions, as they are drowned by those which violated section 87 of the Act. This is because a court of law is not competent to pick depositions in affidavit which are consistent with section 86 of the Evidence Act and ignore those which violate section 87 of the Act. The Court of Appeal was therefore right in rejecting the depositions.
