Answer:
No, because a different outcome would have occurred if state law was applied.
Step-by-step explanation:
Assumption of the risk defense is a law of torts that bars or reduces the plaintiff's right to make a recovery in cases where negligence occurred. The defendant should be able to demonstrate that the plaintiff voluntarily and knowing accepted the risk of participating in an activity.
In the given scenario the spectator is the plaintiff and if the assumption of risk defence is used he will not be able to get a ruling in his favour.
The state allows assumption of risk defence which would have resulted in a ruling in favour of the facility owners.
However the federal court did not allow this defence and ruled in favour of the spectator.
The application of the federal common law was not proper as a different outcome would have occurred if state law was applied.
