Definition of Duty: A legal obligation to ensure the safety of others, established through relationships (e.g., customer-service provider, host-guest).
Examples of Relationships:
Responsibility as a service provider (e.g., shop owner)
Inviting someone into your home.
Customer relationship implies a duty to keep the customer safe.
Determining Breach: Assessing through the lens of a "reasonable person" standard:
Hypothetical reasonable person evaluated to determine if the duty was breached based on their expected actions.
Characteristics of the reasonable person: cautious, responsible, attentive.
If the defendant acted in accordance with this standard, they may not be found liable.
Elements of Causation:
Actual Causation: Linking the breach to the harm.
Example: In the case of Paulsgraf v. New York Railroad (1928), the actions of porters led to the explosion and resulting injuries.
Proximate Causation: Refers to the scope of the potential harms and foreseeability of harm.
Question of Foreseeability: Would a reasonable person foresee harm coming to the plaintiff from the defendant’s actions?
Summary: A gentleman's package containing explosives causes an explosion that injures Mrs. Paulsgraf, who is three blocks away.
Duty Established: The railroad had a duty to care for its customers, including Mrs. Paulsgraf.
Actual Causation: Domino effect from porters pushing a man into the train leading to the explosion and injury.
Proximate Causation: Analyzes whether the harm to Mrs. Paulsgraf was foreseeable given the circumstances.
Special Duties: Landowners have different levels of duties:
Duty to Trespassers: Must avoid willful harm or traps (e.g., a pool).
Duty to Invitees: Must take reasonable steps to ensure safety for guests and customers.
Negligence Per Se: Violation of a pre-existing standard of care (e.g., traffic laws).
Res Ipsa Loquitur: "The thing speaks for itself"; applies when negligence is evident from the circumstances (e.g., keg falling on a parked car).
Contributory Negligence: Complete defense if the plaintiff was even slightly at fault.
Historically strict but seen as unfair; largely replaced by comparative negligence.
Comparative Negligence: Percentages are assigned to each party's fault; plaintiff can recover damages based on their degree of fault.
A person consents to foreseeable risks inherent in an activity.
Requirement: Consent must be informed and voluntary; persons must understand the risks they are assuming.
Example: Waivers at fitness centers stating activity is at your own risk.
Applies to ultra-hazardous activities (e.g., using explosives).
Criteria: Liability is imposed regardless of negligence or intent; just engaging in the activity suffices for liability.
Negligence in Products: Manufacturers must provide warnings when there are risks associated with their products.
Example: Hot beverage warnings on cups.
Defective Product Liability: A manufacturer can be held liable if a product is defective and poses danger to consumers.
Tests for Liability: Consumer expectation test and risk vs. utility test.
Legal time frames established for filing lawsuits. If a lawsuit is not filed within this timeframe, the right to sue may be lost.
