Causation Damages, and Defenses Flashcards
The two types of causation that need to be proven for a valid negligence claim
actual (but-for) and proximate
Actual (but-for) Causation
Causation where, but for the defendant’s breach, the plaintiff would be uninjured.
Evidentiary Requirement for But-For Causation
- In some cases, actual causation requires evidence.
- e.g. plaintiff alleges chemical factory leaked out caused cancer. Plaintiff must prove that the chemical itself causes cancer.
When actual causation is not used
Merged causes and unascertainable cause
Merged Causes
- Two defendants acting independent of each other releasing destructive force into the environment.
- Destructive forces then combine and hurt the plaintiff.
- e.g. two negligently set fires
Liability for Merged Causes
Substantial factor test:
- Ask whether each breach is substantial in contributing to the injury
- Even if alone is not enough to cause injury, D can be liable if combined breach with another person causes injury
Unascertainable Cause
A situation where the plaintiff can’t ascertain who actually caused the harm
Procedure when causation cannot be ascertained
- Burden of proof is shifted to the defendants to prove they are not liable.
- If they can’t meet the burden of proof, they’re jointly liable.
How proximate cause is determined
- Foreseeability.
- Any foreseeable consequences of the defendant’s breach is proximately caused.
What courts consider when determining proximate causation
- Things that happen close by
- Things that happen immediately after
- Things that have happened before
Effect of intervening/supervening causes on proximate causation
- An intervening incident does not break the causal chain.
- A supervening incident does.
Intervening Negligent Medical Issues
- It is foreseeable that { car accident victim would also be subject to med mal.
- But, doctor is still also liable.
Intervening negligent rescue
- Intervening negligent rescue is foreseeable.
- Original defendant typically must pay for those damages too.
Liability for Additional Harm Caused by P to protect themselves from D
- When people cause additional harm to protect themselves from the defendant, the defendant is liable for that additional harm
- e.g. defendant hits your car and you crash into another car. Defendant liable for damage to car you crashed into.
Liability for Subsequent Injuries
- If a person sustains another illness/injury because of illness/injury D caused, D is liable for subsequent injury.
