CONTRIBUTORY NEGLIGENCE; DEFINITION; EFFECT
The defendant seeks to establish that the plaintiff was contributorily negligent.
Contributory negligence is negligence on the part of the plaintiff which, cooperating to some degree with negligence of another, helps in [proximately] [legally] causing an injury to the plaintiff.
The plaintiff may not recover damages if his contributory negligence has contributed more to his injury than the negligence of the defendant. However, if the plaintiff is negligent, he may still recover a reduced sum, so long as his contributory negligence was not greater than the negligence of the defendant.
