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)
IN LAND CASES THE PLAINTIFF MUST SUCCEED ON ITS OWN CASE
In land cases that the plaintiff when claiming a declaration of title must succeed on the strength of his case. The onus lies on the plaintiff to satisfy the court that he is entitled on the evidence brought by him to the declaration of title claimed. The plaintiff must rely on the strength of his case and not on the weakness of the defendant’s case. If this onus is not discharged, the weakness of the defendant’s case may not generally help him and the proper judgment will be for the defendant. Where, however, the case of the defendant lends support to the case of the plaintiff, it is recognised that the court cannot ignore it in arriving at a conclusion as to which side to believe.
