Payne, Janchai

Applicant Janchai Payne claimed cumulative trauma injuries to multiple body parts arising from concurrent employment with UCLA (lab technician) and Los Robles Regional Medical Center (pharmacy technician). The WCJ found applicant's testimony not credible and, based solely on that lack of credibility, found no injury and deemed all other issues moot, deferred, or reserved. The Appeals Board granted reconsideration and held that while credibility is a question of fact for the WCJ, the ultimate determination of injury AOE/COE must be based on medical evidence and not solely on witness credibility. The Board found the WCJ failed to issue findings on the framed ultimate issues, including injury AOE/COE and applicant's requests for an additional internal medicine panel and further discovery. The F&O was rescinded and the matter returned to the trial level for development of the record.
