JESSE SUMABAT vs. CALIFORNIA HIGHWAY PATROL
This case concerns whether the applicant's valley fever is an "insidious, progressive disease" for which jurisdiction over permanent disability can be reserved. The WCAB granted reconsideration, rescinded the initial award, and returned the matter to the trial level. This is because the medical evidence regarding the progressive nature of the applicant's condition was contradictory and required further development. The Board emphasized that the determination of a progressive disease must be supported by substantial medical evidence stating medical probability.
