Sage Club v. Hunt
“The Violent Bartender”
Exercise: Causation and Vicarious Liability
Cooper seeks to dismiss the case against her for two independent reasons:
- Cooper did not breach a duty of care to Boyd.
- Cooper did not proximately cause Boyd’s injuries.
Greene seeks to dismiss the case against her for two independent reasons:
- Cooper putting out the trashcans was an intervening cause of Boyd’s injuries.
- Even if Cooper’s actions were not an intervening cause, Greene still did not proximately cause Boyd’s injuries.
ACME seeks to dismiss the negligence case against it for two reasons:
- ACME is not liable for Greene’s tortious acts because she was acting outside the scope of her employment.
- ACME is not liable because asking Greene to pick up a birthday cake was not a factual cause of Boyd’s injuries.

Four typical scenarios in which factual cause may be contested

- No idea what happened
- Know what happened, but don’t know that it wouldn’t have happened if defendant had behaved reasonably
- Know what happened, but don’t know who to blame

Comparative Negligence
Three forms:
- Pure comparative negligence
- “Not as great as”
- “No greater than”
Comparative Negligence
Three forms:
- Pure comparative negligence
- “Not as great as” = (Plaintiff less than 50% at fault)
- “No greater than” = (Plaintiff 50% or less at fault)

Comparative Negligence Exercise
Plaintiff A has suffered $100,000 of damages in a car accident with B, C, and D.
A now sues B, C, and D for negligence.
Comparative fault of the parties: A - 40%, B - 30%, C - 10%, D - 20%

A now sues B, C, and D for negligence.
Comparative fault of the parties: A - 40%, B - 30%, C - 10%, D - 20%
Question 1: In a traditional common law jurisdiction, how would damages be allocated? Why?

Question 4: Assume the comparative fault of the parties has changed. Under “no greater than” modified comparative negligence, how would damages be allocated? Why?

If multiple defendants are liable, how much are they each paying?
Doctrine of Contribution
Traditional Common Law Approach
Two versions:
- Joint and several liability
- Several liability
Apportionment based on factual cause
Don’t
forget about
factual cause!
Don’t forget about factual cause!
Tortfeasors are only liable for the injuries they caused.
Order of operations with multiple injuries and multiple liable defendants
First step:
Separate injuries based on factual cause.
Second step:
For injuries that multiple defendants caused, sort out liability based on the contribution rule in the jurisdiction.
Doctrine of Contribution
Traditional Common Law Approach
Example:
Four defendants (A, B, C, and D) with $100k damages.
Joint and several liability jurisdiction
A, B, C, and D have plenty of money
Who pays what?

Example: Four defendants (A, B, C, and D) with $100k damages.
A is 40% at fault.
B is 10% at fault.
C is 20% at fault.
D is 30% at fault.

Modern Approach
Apportionment based on comparative fault.
Example: Four defendants (A, B, C, and D) with $100k damages.
A is 40% at fault. So A owes $40k.
B is 10% at fault. So B owes $10k.
C is 20% at fault. So C owes $20k.
D is 30% at fault. So D owes $30k.

Discussion Questions
Given the facts of these cases, what would a just outcome in each case have been?
How capable is our legal system of producing just outcomes in these cases? How does it fall short? What would need to change?
