- assumption of risk
- The doctrine of assumption of risk, also known as volenti non fit injuria, means legally that a plaintiff may not recover for an injury to which he assents, i.e., that a person may not recover for an injury received when he voluntarily exposes himself to a known and appreciated danger. The requirements for the defense of volenti non fit injuria are that:(1) the plaintiff has knowledge of facts constituting a dangerous condition,(2) he knows the condition is dangerous,(3) he appreciates the nature or extent of the danger, and(4) he voluntarily exposes himself to the danger.An exception may be applicable even though the above factors have entered into a plaintiffs conduct if his actions come within the rescue or humanitarian doctrine. Clarke v. Brockway Motor Trucks, D.C.Pa., 372 F.Supp. 1342, 1347.A defense to action of negligence which consists of showing that the plaintiff, knowing the dangers and risk involved, chose to act as he did. An affirmative defense which the defendant in a negligence action must plead and prove. Fed.R.Civil P. 8(c). It is not a defense under state workers' compensation laws or in FELA actions. Many states have abolished the defense of assumption of risk in automobile cases with the enactment of no-fault insurance acts or comparative negligence acts.See also volenti non fit injuria
