Proving Negligence; Vicarious Liability Flashcards
Res Ipsa Loquitor
The thing speaks for itself
- the accident alone is prima facie evidence of negligence
- -Permits but does NOT compel an inference of negligence; provides P w/ common-sense inference of negligence where direct proof of negligence is wanting.
- does not change standard of care BUT does change what the jury does
3 Conditions of Res Ipsa Loquitor
A) Accident must be the type that doesn’t occur without negligence
B) Must be caused by instrumentality within control of D
C) Must not have been due to voluntary action or contribution by P
Byrne v. Boadle
Establishes Res Ipsa Loquitor
McDougald v. Perry
Establishes the 3 conditions of RIL
– must prove 3 conditions by preponderance of the evidence
Ybarra v. Spangard
Very rare application of RIL to medicine
–establishes the compelling of evidence from D’s to establish a clearer understanding of the circumstances
Inference / Presumption
- Inference - if you can infer, find negligent
- Presumption - if the defendant offers no plausible rebutting evidence, the plaintiff is entitled to judgment as a matter of law on liability. If defendant offers such evidence, the jury is to be informed that the plaintiff still bears the burden of persuasion that the defendant was negligent
Restatement §17
Factfinder may infer that the defendant has been negligent when the accident causing the plaintiff’s harm is a type of accident that ordinarily happens as a result of negligence of a class of actors of which the defendant is a relevant member
Inference Standard of RIL
Jury hears, jury can infer based on evidence presented, permitted (not required) to find one way or another
Shifting of Burden of Persuasion
If jury finds elements are met; burden of persuasion is on D – must disprove their negligence
Shifting of Burden of Production
- *If jury finds elements are met; the D has to come forward with something to prove their point (ex. I checked the tire… I tried) OR they lose
- *If D comes with affirmative defense or failure to proof, then jury can decide N or not N.
Vicarious Liability
when one person is held liable for the negligence of another
Respondeat Superior
employers are vicariously liable for torts committed within the scope of employment
Birkner Criteria/Test (factors) “or”
1) Conduct was the kind the employee was hired to perform
2) Within the hours and spatial boundaries of work
2) Actions performed in serving the employer’s interest
Principal Agent Liability
-Similar to Respondeat Superior; btwn principal and agent (independant agent)
Apparent Authority
Determine whether principal created the risk and created the reliance of the third party
- Principal created the appearance of apparent authority AND;
Third party relied on apparent authority and incurred a change/harm
** Exists only where the principal creates the appearance of agency relationship
