Negligence: Causation Flashcards
What is counterfactual inquiry?
What would have happened if the actor had not engaged in the tortious conduct? (used to determine actual cause)
A factual cause
An actor’s tortious conduct need only be “a factual cause” of the other’s harm. the existence of other causes of harm DOES NOT AFFECT whether specific tortious conduct was a necessary condition for the harm to occur.
“Substantial factor” test
Used as an ALTERNATIVE to but-for causation. an actor’s breach is a factual cause if (1) the breach is a substantial factor in bringing about the injury and (2) there is no rule of law that relieves the actor from liability.
Do you need direct evidence of factual causation?
Not always. When establishing causation, MERE SPECULATION or a possibility of causation will not suffice, but INFERENCES ab PROBABILITIES based on ordinary human experience are permissible.
But-for causation
A specific breach must more likely than not cause/contribute to causing the injury.
What is res ipsa for?
BREACH ONLY! That’s why in fedorzcyk, breach was already proved and they didn’t use res ipsa. they were trying to prove causation. she still could’ve slipped even if there were adequate strips bc she had oil all over the place.
Acceleration
An act can also be a factual cause in accelerating an outcome that otherwise would have occurred at a later time. E.g. electrocution (from negligence) causes an acceleration in the death of the victim from natural causes. the loss of the victim’s years of life caused by electrocution provides the framework for determining the damages that would be recoverable in a wrongful death action.
background causes
conditions that exist in the background that must be present for a harm to occur. e.g. oxygen in the air for an explosion.
Multiple sufficient causes
When but-for causation cannot be proven by a preponderance of the evidence, then courts will sometimes find factual causation on policy grounds. If multiple acts occur, EACH OF WHICH ALONE would have been a factual cause of the physical harm at the same time IN THE ABSENCE of other act(s), EACH is regarded as a factual cause of the harm. E.g. two fires are spreading and each alone would destroy a particular house and they meet and burn the house down, then both are factual causes of the injury (even though but for the one fire, the injury still would’ve resulted)
Acting in concert
Two or more parties are in a common enterprise or working together w/ a common goal when ONE commits a negligent act
Acting in concert remedy
Those who act in concert are jointly and severally liable for any harm caused.
Joint and several liability
Each defendant is independently liable for the full extent of the injuries stemming from the tortious act. If one ∆ pays whole damage award, they can seek contributions from the other ∆s.
Joint tortfeasors
Two or more people operating INDEPENDENTLY EACH breach their soc, but the breaches are BOTH NECESSARY causes of the π’s injury.
Joint tortfeasors remedy
Joint tortfeasors are jointly and severally liable for any harm caused.
Alternative Cause Doctrine
Where one or more of the defendants caused the injury and the π cannot REASONABLY be expected to prove which one(s) actually caused the harm, then the court will then SHIFT THE BURDEN of proof to the ∆s on the issue of FACTUAL CAUSATION. Summers v. Tice
