TRIAL JUDGE HAS THE PRIMARY FUNCTION OF EVALUATING EVIDENCE

DUTY OF TRIAL COURT; PERCEPTION & EVALUATION OF EVIDENCE

There is a duty in a trial court to receive all available relevant evidence on an issue. This is perception of evidence. After that there is another duty to weigh that evidence in the context of the surrounding circumstances of the case. This is evaluation of evidence. A finding of fact will entail both perception and evaluation. But very often in actual practice it is difficult to say when perception ends and evaluation begins.

EVALUATION OF EVIDENCE AND IMAGINARY SCALE

Re-evaluation suggests and presupposes a prior evaluation. If evidence has already been evaluated by the trial Court, on what grounds, on what basis, on what principles would an appellate court undertake another re-evaluation of the same evidence? Before tackling this main issue, it may be necessary to dispose of a subsidiary but related issue: What does evaluation of evidence consist of? What is the meaning of the expression evaluation? To evaluate simply means to give value to, to ascertain the amount, to find numerical expression for etc. Thus if a plaintiffs case is supported by witnesses, while the defendant’s case is supported by 6 witnesses then the numerical expression, the quantum of evidence, the amount, would be 4 to 6. If cases are decided solely by the number of witnesses called by either side, then in the above instance the plaintiff will lose, having a preponderance of 6 witnesses to 4 witnesses in the scale against him. Now talking of scale naturally leads one to the famous dictum of Fatayi Williams, J.S.C.(as he then was) in A.R. Mogaji and ors v. Madam Rabiatu Odafin and ors (1978) 4 S.C.91 at 93:- “When an appellant complains that a judgment is against the weight of evidence, all he means is that when the evidence adduced by him is balanced against that adduced by the respondent, the judgment given in favour of the respondent is against the weight which have been given to the totality of the evidence before him, (the trial Judge) ….. Therefore in deciding whether certain set of facts given in evidence by one party in a civil case before a court in which both parties appear is preferable to another set of facts given in evidence by the other party, the trial Judge, after a summary of all the facts, must put the two sets of facts on an imaginary scale, weigh one against the other, then decide upon the preponderance of credible evidence which weighs more, accept it in preference to the other, and then apply the appropriate law to it ….” (italics ours). This scale though imaginary is still the scale of justice, and the scale of truth. Such a scale will automatically repel and expel any and all false evidence. What ought to go into that imaginary scale should therefore be no other than credible evidence. What is therefore necessary in deciding what goes into the imaginary scale is the value, credibility and quality as well as the probative essence of the evidence.

APPEAL COURT IS IN A POSITION TO RE-APPRAISE EVIDENCE ON RECORD

I have gone through the evidence of the witnesses on record and the judgment of the trial Court and I am firmly of the view that there was no issue of the trial court’s assessment of the credibility of witnesses. The result is that this Court, like the court below, is in as good a position as the trial court to appraise or re-appraise the evidence on record to see if the concurrent findings of the two courts below are not perverse. With respect to the evidence itself, there is a lot of oral as well as documentary evidence. I am however of the view that the issues raised would be resolved mainly by the documentary evidence. I am guided in this view by the settled principle of law that oral evidence is only to be hangars on for documentary evidence.

FOR AN EVIDENCE TO BE RELIED UPON, IT MUST HAVE COGENCY OR PROBATIVE VALUE

The law does not permit evidence which is of no probative value to be relied upon by a party, nor to be acted upon by the court, to support a claim. It is an important aspect of civil procedure that for evidence to be considered useful and which a court can act upon, there are certain basic qualities it must possess. The first consideration is usually the double requirement of relevancy and admissibility. But in essence they can be separated. The evidence must be relevant to a fact in issue, or to any fact which, though not in issue, is so connected with the fact in issue, or relevant to a fact which is inconsistent to any fact in issue or to a fact which by itself or in connection with any other fact makes the existence or non-existence of any fact in issue probable or improbable. S.7 & 12 Evidence Act. It must be admissible having regard to the facts pleaded and if no law or rule precludes its admission: see Emegokwue v. Okadigbo(1973) 4 SC 113; Onobruchere v. Esegine (1986) 1 NWLR (PU9) 799. It must have credibility or cogency thereby enabling the Judge to ascribe some probative value to it having regard to its nature and what it is intended to establish: Misr (Nig.) Ltd. v.Ibrahim (1974) 5 SC 55 at 62; Aikhionbare v. Omoregie (1976) 12 SC 11 at 27. I have had to state the above because Exhibit V neither has cogency nor any probative value which can be ascribed to it.

WHEN WEIGHT OF EVIDENCE IS ALLEGED, MEANING

In the case of AWUSA v. NIG. ARMY (2018) LPELR-44377 (SC) the Apex Court held that: “The position of the law is that when an Appellant alleges that a decision is against the weight of evidence, he means that when evidence he adduced is balanced against that of the Respondent. Judgment in the Respondent’s favour is against the weight that should have been given to the totality of the evidence adduced – See Akinlagun v. Oshoboja (2006) 12 NWLR (Pt. 993) 60 at 82 SC. The complaint is only concerned with appraisal and evaluation of all the evidence and not the weight to be attached to any particular piece of evidence…”
