It is settled that negligence is a question of fact and not of law. So, each case must be decided in the light of facts pleaded and proved. No one case, is exactly like another. – NIMPAR, J.C.A. Diamond Bank v. Mocok (2019)
ONUS OF PROVING NEGLIGENCE IS ON THE CLAIMANT
The onus of proving negligence is on the claimant who alleges it and unless and until that is proved, the onus of proof does not shift. In other words, where a claimant pleads and relies on negligence by conduct or action of a defendant, the claimant must prove by evidence the conduct or action and the circumstance of its occurrence which gave rise to the breach of the duty of care owed the claimant. It is only after this that the burden shifts to the defendant to adduce evidence to challenge the negligence on his part Universal Trust Bank of Nigeria Plc Vs Ozoemena supra.
