It is settled law that where the party offers no evidence in defence of the case of the plaintiff, the burden placed on the plaintiff is minimal, since there is no evidence to challenge the case of the plaintiff and the plaintiff can use the unchallenged evidence to establish his case. – Onnoghen JSC. Chami v. UBA (2010)
CIVIL SUIT IS DECIDED ON THE BALANCE OF PROBABILITIES
Now, civil suits are decided on the balance of probabilities, on the preponderance of evidence. The burden of proof is not static but shifts and the onus of adducing further evidence is on the person who will fail if such evidence is not adduced. See Osuji v Eke [2009] 16 NWLR (Pt 1166) 81.
