Adamson v. Municipality of Anchorage, 333 P.3d 5

Adamson, a longtime firefighter for the Municipality of Anchorage, was diagnosed with prostate cancer in 2008 after ~30 years on the job.
AS 23.30.121 (effective Aug 19, 2008) creates a presumption that listed diseases, including prostate cancer, are work-related for firefighters who meet defined medical-examination and exposure criteria.
The statute requires a qualifying medical examination at hire and annual exams for seven years, plus exposure to a known carcinogen associated with the cancer.
The Board initially approved benefits, finding Adamson attached the presumption by substantial compliance; the Commission remanded on rebuttal evidence.
Issues included retroactive application of the statute’s requirements and whether the Municipality could rebut the presumption with expert testimony that there is no known carcinogen for prostate cancer.
The Alaska Supreme Court held that Adamson attached the presumption by substantial compliance and reversed the Commission on allowing rebuttal testimony that there is no known carcinogen for prostate cancer.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Substantial vs strict compliance	Adamson: substantial compliance suffices and retroactivity applies.	Municipality: strict compliance required; regulation may not apply retroactively.	Substantial compliance suffices; retroactive application recognized.
Rebuttal evidence admissibility	Presumption cannot be defeated by general causation arguments; evidence must relate to claimant’s exposure.	Municipality: may use expert on no known carcinogen to rebut presumption.	Municipality may not rebut via testimony that no known carcinogen exists for prostate cancer; error to admit.
Exposure and association standard	Show exposure to known carcinogens and evidence linking them to prostate cancer satisfies statute’s two-step approach.	Argues need for stricter causation proof tying exposure to the specific cancer.	Two-step process shown: exposure to known carcinogens and association with prostate cancer suffices.
