Narrative Opinion Summary
The case involves a dispute over workers' compensation liability concerning a 1994 back injury sustained by a claimant, a log truck driver previously employed by multiple companies. The claimant had a history of back issues, originally injured in 1980 and again in 1989 while working for Willamette Industries. The Workers' Compensation Board found Willamette liable for the 1994 injury, affirming that the 1989 injury was the major contributing factor despite the claimant's subsequent employment with Pacific Gas and Transmission (PGT), which was deemed physically undemanding. The Board rejected Willamette's attempt to apply the last injurious exposure rule to shift liability to PGT, as there was no evidence that the claimant's subsequent job contributed to his condition. Dr. Kendrick's medical opinion, initially attributing the injury to a 1980 incident, was revised to support the finding that the 1989 injury was the primary cause of the 1994 herniation. The court upheld the Board's conclusion, emphasizing that the rule of last injurious exposure could not be used defensively without evidence of a subsequent contributing injury. Consequently, Willamette remained liable for the claimant's compensable injury under ORS 656.308, aligning with the Board's decision that the 1994 injury did not constitute the same condition as prior claims.
