Admissibility is a rule of evidence and it is based on relevancy. See Sadau v. The State (1968) 1 All NLR 124: Ogonzee v. State (1997) 8 NWLR (Pt. 518) 566. In determining the admissibility of evidence, the court will not consider how it was obtained; rather the court will take into consideration whether what is admitted is relevant to the issues being tried. See Igbinovia v. The State (1981) 2 SC 5. In Elias v. Disu (1962) 1 SCNLR 361, (1962) 1 All NLR 214, this court held that in determining admissibility of evidence, “it is the relevancy of the evidence that is important and not how the evidence was obtained.”
