Failure to Halt Accomplice Crime
Leonard Lowe learned that his adult son planned to set fire to a vacant warehouse. Lowe had a prior legal obligation arising from his role as the property's court-appointed custodian to stop any criminal damage. He watched the son gather materials but made no call to police or attempt to intervene. The warehouse burned and Lowe faced accomplice liability for the arson.
Preexisting Duty in Contract Modification
Luke Latham already owed Landmark Realty a contractual duty to complete roof repairs for a fixed price. When heavy rain caused extra damage, Latham demanded an additional $15,000 to finish the job. Landmark agreed in writing but later refused payment. The court held the promise unenforceable because Latham merely performed the same preexisting legal duty.
Landowner Duty to Contractor Employee
Levi Lowe worked for Lighthouse Shipping inside a warehouse owned by Lone Peak Energy. Lone Peak retained exclusive control over all safety labeling on high-pressure valves. A faded label caused Lowe to open the wrong valve and suffer burns. The facts established that Lone Peak owed Lowe a legal duty to maintain accurate safety markings.
Public Record Created Under Reporting Duty
Lily Lopez, a county health inspector, observed missing pool fencing during a required sanitary inspection of a hotel. She recorded the violation on an official form that state law required her to complete and file. At trial the form was offered to prove the condition on the date of inspection. The record qualified for admission because Lopez prepared it while under a legal duty to report.
Court Decides Existence of Duty
Lucy Liu slipped on an unmarked wet floor inside a store owned by Loyal Insurance's client. The store manager had posted no warning despite knowing of recurring leaks. At summary judgment the court first determined whether the facts gave rise to any legal duty on the part of the store. Finding that a possessor owes invitees a duty to warn of known hazards, the court allowed the negligence claim to proceed to the jury.
Vital Record Admitted Under Duty to Report
Lena Lawson died at a hospital after a fall. The attending physician completed the death certificate listing the cause as accidental trauma and filed it with the county vital records office as state law required. In a later insurance dispute the certificate was offered to prove the cause of death. The document was admissible because it recorded a death reported to a public office in accordance with a legal duty.
Common questions
Frequently Asked
5
What must a plaintiff prove to establish that a defendant owed a legal duty in a negligence case?+
The plaintiff must show facts that give rise to a legal duty on the part of the defendant to conform to the standard of conduct established by law for the protection of the plaintiff. The court decides whether those facts create any legal duty. Once duty is found the jury determines whether the defendant conformed to the required standard.
When does performance of a preexisting legal duty fail to supply consideration for a contract modification?+
Performance of a legal duty owed to the promisor that is neither doubtful nor the subject of honest dispute is not consideration. A similar performance supplies consideration only if it differs from what the duty required in a way that reflects more than a pretense of bargain.
How does a legal duty to prevent an offense create accomplice liability under the Model Penal Code?+
A person becomes an accomplice if, with the purpose of promoting or facilitating the offense, the person has a legal duty to prevent the commission of the offense and fails to make a proper effort to do so.
When is a public record admissible under the hearsay exception for matters observed under a legal duty to report?+
A record of a public office is admissible if it sets out a matter observed while under a legal duty to report, provided the opponent does not show lack of trustworthiness. In criminal cases the exception excludes matters observed by law-enforcement personnel.
What makes a vital record admissible as an exception to the hearsay rule?+
A record of a birth, death, or marriage is admissible if it was reported to a public office in accordance with a legal duty. The exception rests on the official obligation to create and maintain accurate vital statistics.
