The Estate of Kurt Aikele v. City of Blackfoot, 382 P.3d 352

Kurt Aikele, a lifelong non-smoker, served 26 years as a Blackfoot firefighter and was diagnosed with lung adenocarcinoma in 2008; he died in 2012. He filed a workers’ compensation claim (later amended to seek death benefits) alleging occupational causation.
Key factual disputes: whether Aikele wore SCBA during mop-up, whether he was exposed to diesel fumes in the firehouse, and what specific carcinogenic exposures (and in what amounts) he experienced.
Medical evidence: Aikele’s treating oncologist, Dr. Dane Dickson, opined the occupation likely caused the cancer but acknowledged uncertainty and lacked specifics on exposures. The Idaho State Insurance Fund presented Drs. George Pfoertner and Norman Zuckerman, who concluded occupational causation was unlikely; Zuckerman relied in part on a meta-analysis finding no statistically significant increased lung cancer risk for firefighters.
The Industrial Commission credited Zuckerman and Pfoertner over Dickson, found gaps in proof about specific exposures and exposure levels, and denied compensability because Aikele did not prove causation by a preponderance of the evidence.
The Idaho Supreme Court affirmed, holding the Commission’s factual findings were supported by substantial, competent evidence and that Idaho Code §72-438(12) did not relieve Aikele of the ordinary burden to prove occupational causation.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Commission findings of fact were clearly erroneous	Aikele: Commission misstated/discounted evidence and experts; factual findings contradicted record	ISIF: Commission properly weighed conflicting testimony and expert reasoning	Held: Findings not clearly erroneous; credibility/weight for Commission to decide
Whether order was supported by substantial and competent evidence	Aikele: Meta-analysis is irrelevant to causation; Dr. Dickson’s opinion supports occupational causation	ISIF: Meta-analysis and independent experts provide substantial evidence against causation; claimant’s proof was insufficient	Held: Supported by substantial competent evidence favoring ISIF experts over Dickson
Whether §72-438(12) creates a presumption or relaxes plaintiff’s burden	Aikele: Statute identifies firefighters’ pulmonary diseases as compensable and should ease proof of causation	ISIF: Statute requires disease be "caused by" occupational exposures; ordinary causation rules apply	Held: Court: statute’s plain language requires causation; Commission applied correct burden (preponderance)
Entitlement to attorney’s fees under I.C. §72-313	Aikele: Requests fees citing the statute	ISIF: Argues no basis; appellant did not prevail	Held: Denied — citation without argument is insufficient and appellant did not prevail
