Street v. Weyerhaeuser Co. (Majority)Annotate this Case
Weyerhaeuser Company challenged an award of industrial insurance benefits to its former employee, Roger Street, for his low back condition, a claimed occupational disease. Weyerhaeuser argued that a worker must present expert medical testimony that the disease "arises naturally" out of employment. The Court of Appeals rejected Weyerhaeuser's argument, holding that the controlling case law required Street to present expert medical testimony to show that his back condition "arose naturally" from employment. Because there was medical testimony supporting the "arises proximately" requirement and lay testimony supporting the "arises naturally" requirement, the appeals court held that Street proved his low back condition was an occupational disease and affirmed the jury award of benefits. Finding no reversible error in the Court of Appeals’ decision, the Washington Supreme Court affirmed.
