In Comfort Asaboro v. M.G.D. Aruwaji and Anor. (1974) 4 SC 87 at 90-91 (Reprint) this court had cause to consider the principles which are to be taken into consideration in an application to call additional evidence on appeal. The court per Coker JSC said:- “The decision also evidently applied the principles which time honoured practice has established and the matters which the courts have always taken into consideration in the judicious exercise of powers to grant leave to adduce new evidence, namely:- The evidence sought to be adduced must be such as could not have been with reasonable diligence obtained for use at the trial; The evidence should be such as if admitted, it would have an important, not necessarily crucial, effect on the whole case; and the evidence must be such as apparently creditable in the sense that it is capable of being believed and it need not be incontrovertible. See for these observations Roe v. R McGregor and Sons Ltd. (1968) 1 WLR 925 where the earlier decision of the Court of Appeal in Ladd v. Marshall (1954) 3 All ER 745 was considered and applied. Strictly speaking, under our own rule, the discretion to grant leave to adduce new evidence is properly exercised for the “furtherance of justice”. The exercise must however be judicious and it is in this respect that the guidelines set out above have been followed and applied. We are not unmindful of the fact that it would be a dangerous precedent to allow a person who did not call evidence in the lower court, or who, for one reason or another, had called insufficient evidence at the trial, with comparative ease, to bring forward for the first time before this court the evidence which could and should have been adduced before the trial Judge. Such an attitude would be disastrous to the principles of seeing an end to litigation. The stand taken by the Privy Council in the case of Edie Maud Leeder v. Nnance Ellis (1953) at 52 (sic) also illustrates this point. However one looks at the problem, it seems to be generally accepted that the guiding principles have always been applied to the special facts or circumstances of each application before the Court of Appeal, and in every case the question whether or not sufficient diligence has been put into the quest for such evidence has been decided as a matter of fact.”
CLAIMANT MUST RELY ON THE STRENGTH OF HIS OWN CASE AND SUPPORT FROM EVIDENCE OF DEFENDANT
I bear in mind the well-established principle of law that in every civil action in which a declaration is sought from the Court, a claimant who seeks the declaratory relief must succeed on the strength of his own case as made out creditably in the evidence put forward by him in support of his case and not to merely rely on the weakness or even absence of the Defendant’s case. However, where the evidence of the Defendant supports the case of the claimant, he is perfectly entitled to rely on such evidence. See Nsirim v Nsirim (2002) FWLR (pt. 96) 433 @ p. 441.
