Shanks v. Davey Tree Surgery Co.

Citations: 173 Ariz. 557; 845 P.2d 483; 117 Ariz. Adv. Rep. 46; 1992 Ariz. App. LEXIS 194Docket: No. 2 CA-CV 92-0009

Court: Court of Appeals of Arizona; July 14, 1992; Arizona; State Appellate Court

Narrative Opinion Summary

In this personal injury case, the appellants contested a summary judgment granted in favor of the appellee, Davey Tree Surgery Company, on the grounds of negligence. The appellants argued that Davey had either a contractual obligation or had voluntarily undertaken duties on behalf of Tucson Electric Power Company (TEP) to ensure public safety concerning power lines. The incident involved an injury sustained by a tree trimmer due to contact with an uninsulated power line. The court upheld the summary judgment, emphasizing that determining duty is a legal question and found no evidence that Davey owed a duty to the injured party. It was determined that the contractual relationship required Davey to perform tree trimming as directed by TEP but did not transfer TEP's legal obligations to Davey. Additionally, the appellants failed to demonstrate that Davey assumed any responsibilities under Restatement (Second) of Torts, Section 324A, as there was no increased risk of harm, reliance, or assumption of TEP's duties. As a result, the court affirmed the previous decision, concluding that without a duty owed by Davey, there was no basis for a breach of duty claim.

Legal Issues Addressed

Absence of Duty and Breach in Negligence Claims

Application: Without an established duty of care, a claim of breach of duty in negligence cannot proceed.

Reasoning: Therefore, since Davey did not owe a duty to Shanks, the arguments regarding breach of duty need not be considered.

Assumption of Duty under Restatement (Second) of Torts, Section 324A

Application: Davey did not assume a duty to protect third parties as there was no evidence of increased risk, reliance on services, or assumption of TEP's obligations.

Reasoning: However, Shanks fails to establish the requisite elements: there is no evidence that Davey’s inaction increased the risk of harm (Section 324A(a)), nor did Shanks demonstrate reliance on Davey’s services (Section 324A(c)).

Contractual Obligations and Interpretation

Application: Differing interpretations of contract terms are insufficient to establish ambiguity; the language must reflect clear party intentions.

Reasoning: The mere existence of differing interpretations of the contract does not create ambiguity; the contract's language reflects the parties' intentions and is interpreted based on the common meaning of the words used.

Determination of Duty in Negligence Cases

Application: The court clarifies that determining whether a duty of care exists is a legal question, which forms the foundation of negligence claims.

Reasoning: The court affirms the summary judgment, noting that the determination of duty is a legal question.

Duty of Utilities under National Electrical Safety Code

Application: Utilities are required to maintain power lines safely and take proactive measures against interference, but this duty does not extend to contractors absent a clear assumption of obligations.

Reasoning: Utilities, including TEP, have a legal obligation to maintain power lines safely and comply with the National Electrical Safety Code, which requires proactive measures against tree interference with power lines.
