Now before proceeding to analyse the evidence, let me restate the legal consequences on the issue of burden of proof when a claim is founded on customary tenancy. It is settled principle of law that a claim which seeks a declaration that the Defendants are customary tenants of the plaintiff and other consequential reliefs emanating there from postulates that the Defendants are in exclusive possession of the land in dispute, and by the operation of Section 146 of the Evidence Act Cap. E14 of the Laws of the Federation, there is presumption that the Defendants in such exclusive possession are the owners of the land in dispute until the contrary is proved to rebut that presumption. The only way to rebut the presumption is by strict proof of the alleged customary tenancy. That is the danger of a plea founded on the allegation of customary tenancy.
