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)
COURT WILL ACT ON UNCHALLENGED EVIDENCE
The law is well settled that where the evidence given by a party to any proceedings was not challenged by the opposite party who had the opportunity to do so, it is always open to the court seised of the case to act on such unchallenged evidence before it. See Isaac Omoregbe v. Daniel Lawani (1980) 3 – 4 SC 108 at 117, Odulaja v. Haddad (1973) 11 SC 357, Nigerian Maritime Services Ltd. v. Alhaji Bello Afolabi (1978) 2 SC 79 at 81, Abel Boshali v. Allied Commercial Exporters Ltd. (1961) 2 SCNLR 322, (1961) All NLR 917.
