In Ehman v. Dept. of Labor & Indus., 33 Wn.2d 584, 206 P. 2d 787 (Wash. 1949), the Supreme Court of Washington upheld an administrative order denying compensation to an employee who claimed to have developed Dupuytren's contracture because, for more than 20 years, he lifted and carried bundles of wooden flooring.
After summarizing evidence in the record that "many persons suffer from the disease who have not been engaged in occupations which would be likely to result in traumatic injury to the hands," Id. at 791, the appellate court said that "the most that can be said is that respondent's unfortunate physical condition may be or possibly is an occupational disease. This is not sufficient..." Id. at 797.
