Also in Duru v. Onwumelu (2001) 18 NWLR (Pt. 746) 672 at 696—697, H—D per Uwaifo JSC: ‘Now, by relying on acts of possession in proof of title to the land in question, the plaintiffs as a community inevitably put in issue the totality of the numerous acts of possession and ownership they claim to have been enjoyed by them, the positive nature of those acts and the long period over which the said acts have spanned so that the circumstance as a whole will be seen to have come within the principle long laid down in Ekpo v. Ita (1932) 11 N.L.R. 68. Simply put in relation to this case where, as already said, the plaintiffs base their right to a declaration of title to the land on the fact of long possession, the principle is that they must prove acts of ownership and possession of the land in dispute over a sufficient length of time, numerous and positive enough to warrant the inference that they are exclusive owners. In my view, it will not do if merely there are numerous acts, since these might qualify, on the part of an intrusive party, as acts of trespass. There is the requirement that the acts ought to extend over a sufficient or appreciable period of time and must be positive. To be positive, the acts ought to be such that can be verified upon strong evidence, such as, old structures and settlements, well-beaten roads or paths, economic crops or trees tending visibly to be long-lived, old farms and huts, community shrines which have long been in existence, and to which the plaintiffs as a community can satisfactorily lay claim etc.’
