EVALUATION OF EVIDENCE ENTAILS

PRINCIPLES WHICH APPELLATE COURTS SHOULD CONSIDER IN THE EVALUATION OF EVIDENCE

And that takes me to the principles which an Appellate Court should consider in the evaluation of evidence by the trial Judge: 1. Evaluation of trial evidence is the primary responsibility of the trial court and so an Appellate Court cannot interfere just for the asking by an appellant. 2. An Appellate Court will however evaluate the evidence before the court if the trial court fails to do so; and this is from the Record. 3. An Appellate Court will also evaluate the evidence before the court if the trial court failed to evaluate the evidence properly in the sense that the evaluation is perverse. And so, the evaluation of evidence, though the primary responsibility of the trial court, is not the exclusive preserve of that court. It becomes so only where the evaluation is borne out from the evidence before the court.

COURT SHOULD NOT ACT ON INADMISSIBLE EVIDENCE WHERE ADMITTED

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.”

COMPETENCY IS A MATTER OF UNDERSTANDING

And, apart from this, there is a long line of authorities establishing that competency is not a matter of age but of understanding and that if a child understands the nature of an oath, the provisions in question are completely out of place. See Reg. v. Perkins (1840) 9 C. & P. 395 (or 173 E.R.884); also R. v. Michael Moscovitch (1924) 18 CAR 37. – Coker JSC. Okoye v. State (1972)

WRONG EVALUATION OF EVIDENCE BY TRIAL COURT

Where the Court of Appeal wrongly evaluates the evidence before the trial court and arrives at a wrong conclusion not borne out from the evidence before the court, the Supreme Court will intervene on the ground that the finding is perverse. But where the finding of the Court of Appeal is borne out from the evidence adduced in the trial court, this court cannot intervene. I do not see any reason for intervention in this appeal.

AFFIDAVIT EVIDENCE CONSTITUTES EVIDENCE

It is already a settled law that an affidavit evidence constitutes evidence and must be so construed, hence, any deposition therein which is not challenged or controverted is deemed admitted.
