James Wieboldt vs. County of San Diego
The Appeals Board rescinded two WCJ findings of industrial colon and vocal cord cancer, returning the cases for further proceedings. The Board found the medical opinions of Drs. Woolf and Berman lacked substantial evidence due to issues with causation, exposure details, and reliance on incorrect legal presumptions. While the applicant has the burden to prove industrial causation absent the cancer presumption, the Board determined the current medical record requires further development. The Board also noted discrepancies regarding the applicant's job titles and claimed periods of exposure that need clarification.
