Luis M. Mariscal vs. Blakeley Construction, State Compensation Insurance Fund

This case involves a workers' compensation claim for a back injury where the defendant seeks reconsideration of the permanent disability rating. The core issue is whether to apportion a portion of the disability to the applicant's pre-existing pathological condition, despite the evaluating physician's potentially contradictory opinion. The Appeals Board granted reconsideration, rescinded the prior award, and returned the matter for a new rating consistent with apportionment principles established in recent case law.
