California Code, Labor Code - LAB § 5901

No cause of action arising out of any final order, decision or award made and filed by the appeals board or a workers' compensation judge shall accrue in any court to any person until and unless the appeals board on its own motion sets aside the final order, decision, or award and removes the proceeding to itself or if the person files a petition for reconsideration, and the reconsideration is granted or denied. Nothing herein contained shall prevent the enforcement of any final order, decision, or award, in the manner provided in this division.
