Trespasser Encounters Hidden Hazard
Wade Watson enters Windham Technologies property at night to retrieve a lost tool. The company knows of an unmarked excavation pit that has caused serious injuries to others. No signs or barriers alert Watson to the pit. He falls in and sustains a broken leg. The company faces liability for failing to warn him of the condition.
Physician Receives Drug Warning
Winston West's doctor prescribes a medication manufactured by Walker Valley Produce. The manufacturer supplies the doctor with complete risk information about potential liver damage. Winston later suffers liver failure and sues the manufacturer for failing to warn him directly. The manufacturer avoids liability because the warning to the physician was adequate.
Self-Defense Force Assessment
Winter Wolfe confronts an attacker who threatens serious injury. Wolfe uses a level of force that a reasonable person would recognize could cause permanent loss of limb function. The court evaluates whether the intended harm qualifies as serious bodily harm under the governing standard.
Device Manufacturer Warns Doctor
Willa Whitman receives a medical implant from Warwick Electronics. The company provides the implanting physician with full warnings about infection risks. Whitman develops an infection and claims the manufacturer failed to warn her personally. Liability does not attach because the duty runs to the physician.
Causation in Device Warning
Winston Ward's physician implants a device made by Wrightway Engineering. The manufacturer gives the physician generalized risk data. Ward sues after complications arise, offering only evidence that the physician knew of risks in the abstract. The claim fails because no proof shows that a better warning would have changed the prescribing decision.
Frequently Asked3
Does a manufacturer satisfy its duty to warn by informing only the prescribing physician?+
Yes. Under the learned intermediary doctrine, the manufacturer's duty to warn runs to the physician rather than the patient. The physician evaluates risks and benefits for the individual patient, so adequate warnings to the physician break the causal chain to the patient.
Supporting sources
When must a land possessor warn a trespasser of a dangerous condition?+
A possessor must exercise reasonable care to warn a known trespasser of an artificial condition that is likely to cause death or serious bodily harm and that the trespasser is unlikely to discover. Failure to provide such a warning creates liability for resulting physical harm.
Supporting sources
What must a plaintiff show to overcome the learned intermediary doctrine?+
A plaintiff must prove that the warning given to the physician was inadequate or misleading and that an adequate warning would have altered the physician's prescribing decision. Generalized evidence that the physician knew of risks in the abstract is insufficient.

Miranda v. Arizona384 U.S. 436 (1966)
384 U.S. 436 (1966)Evidence
…(1963). In order fully to apprise a person interrogated of the extent of his rights under this system then, it is necessary to warn him not only that he has the right to consult with an attorney, but also that if he is indigent a lawyer will be appointed to represent him. Without this additional warning, the admonition…
