In the case of Olukade v Alade (1976) 2 SC 183, this Court summarised the general rule on the effect of the admission of inadmissible evidence:- “A court is expected in all proceedings before it to admit and act only on evidence which is admissible in law (i.e. under the Evidence Act or any other law or enactment relevant in any particular case or matter) and so if the court should inadvertently admit inadmissible evidence it has the duty not to act upon it.”
TAKING EVIDENCE BY HIGH COURT INSTEAD OF MAGISTRATE COURT
It seems to me that if under the provisions of Order 23, rule 54 of the High Court Rules of Anambra State, 1988 a Magistrate or any officer of the court is permitted to take the evidence of a witness by way of commission, it cannot, with respect, be right to suggest that a High Court Judge, a judicial officer with much higher jurisdiction and status than a Magistrate or any other officer of the court is incompetent to take such evidence unless there exists any law which stipulates to the contrary. I know of no such law and my attention has not been drawn to any in this appeal. I am therefore of the view that the High Court was right by taking the evidence of the fourth defendant by way of commission as urged upon the court by learned Counsel for the appellant.
