Court of Appeals of Oregon October 2, 2002, 98-0327; A114206 (Kniss v. Public Employees Retirement Board)

*49

LANDAU, J.

The Public Employees Retirement Board (board) denied claimant’s request for disability retirement benefits on the ground that he had failed to establish that employment was the cause of his coronary arteiy disease. Claimant seeks review, arguing that the board erred in requiring him to prove that employment was more than merely a contributing factor to his disease. We affirm.
