The Supreme Court in Ohijinle vs. Adeagbo (1988) 2 NWLR (Pt. 75) 238 held that where documentary evidence have been admitted in evidence, demeanour plays an insignificant if any role. The documents tendered in the case should be used as a hanger with which to assess oral testimony.
ESTIMATE OF REPAIRS DOES NOT SUFFER FROM INADMISSIBILITY (DUE TO BEING AN INTERESTED PERSON)
This Court has held that estimate of repairs though made during the pendency of the suit does not suffer from the disability of S.91(3) of the Evidence Act because the maker of the estimate was not an interested party in the suit. An interested party contemplated in the exclusion of evidence or disqualification therefore is a person who is interested in the outcome of the litigation. See IGBINOVIA v. AGBOIFO (2002) FWLR (Pt. 103) 505 at 517, OWENA BANK PLC, v. CHIEF OLATUNJI and ORS. (2002) FWLR (Pt. 124) 529 at 591. The overriding raison d’etre of the legislation in my humble view is that the Courts would not allow a person interested to cook up a statement during the pendency of a suit or its anticipation in order to defeat the course of justice. In UGWU v. ARARUME (2007) 6 SCNJ Pg.316 at 354 – 355, the Supreme Court held that even though PDP was not a party in the proceedings at the material time, the document made by PDP was inadmissible under S.91 (3) because they were interested in the outcome of the litigation between UGWU v. ARARUME.
