Rodney McMillan vs. CITY OF RIVERSIDE
Applicant, a police officer, sought reconsideration after a WCJ denied his heart trouble claim under Labor Code § 3212.5. The parties stipulated the heart trouble presumption applied, shifting the burden to the employer to rebut it. While the Agreed Medical Examiner identified alcoholism as the probable cause of applicant's cardiomyopathy, he could not definitively state it was the "sole cause" or that employment played no role. The Appeals Board granted reconsideration, rescinded the original order, and remanded the case for further proceedings to determine if the presumption was adequately rebutted.
