Cal. Lab. Code § 5507

If an application shows upon its face that the applicant is not entitled to compensation, the appeals board may, after opportunity to the applicant to be heard orally or to submit his claim or argument in writing dismiss the application without any hearing thereon. Such dismissal may be upon the motion of the appeals board or upon motion of the adverse party. The pendency of such motion or notice of intended dismissal shall not, unless otherwise ordered by the appeals board, delay the hearing on the application upon its merits.
