LEGAL PRINCIPLE: EVIDENCE LAW – Burden of Proof in Civil Cases – Plaintiff Must Prove Case on Balance of Probabilities
PRINCIPLE STATEMENT
In civil cases, proof is based on the balance of probabilities. The burden of proof rests on the plaintiff who asserts the affirmative, and he must discharge it.
RATIO DECIDENDI (SOURCE)
Per Ogwuegbu, JSC, in Daudu v. Nigerian National Petroleum Corporation (1998) NLC-2201994(SC) at p. 14; Paras C–D.
"In civil cases, proof is based on balance of probabilities. The burden of proof in this case rested on the plaintiff who asserted the affirmative and he did not discharge it."
EXPLANATION / SCOPE
The civil standard of proof is the balance of probabilities. The plaintiff bears the burden of proving his case. The burden never shifts to the defendant. The plaintiff must adduce sufficient evidence to tilt the scale. The principle is fundamental to civil procedure. The court will dismiss the claim if the plaintiff fails to discharge the burden. The rule applies to all civil cases, including land disputes, contracts, and torts. The plaintiff cannot rely on the weakness of the defence. The standard is the same for all civil claims.
