Claim of Terwilliger v. Green Fuel Economizer, Inc.
The claimant appealed a Workers' Compensation Board decision, challenging both the apportionment of his award between an industrial accident and a pre-existing condition, and the board's finding of moderate disability. The court emphasized that full compensability hinges on whether the industrial accident activated a previously dormant and non-disabling pre-existing condition. Despite the claimant's attending physician testifying that his pre-existing condition was asymptomatic prior to the accident, the record contained evidence of prior low back problems. The court reiterated that resolving conflicting medical evidence, concerning both apportionment and the degree of disability, falls exclusively within the Board's purview. Since the Board's decision was supported by substantial evidence, the appellate court affirmed it.
