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.

The petition for reconsideration shall set forth specifically and in full detail the grounds upon which the petitioner considers the final order, decision or award made and filed by the appeals board or a workers’ compensation judge to be unjust or unlawful, and every issue to be considered by the appeals board. The petition shall be verified upon oath in the manner required for verified pleadings in courts of record and shall contain a general statement of any evidence or other matters upon which the applicant relies in support thereof.

At any time within 20 days after the service of any final order, decision, or award made and filed by the appeals board or a workers’ compensation judge granting or denying compensation, or arising out of or incidental thereto, any person aggrieved thereby may petition for reconsideration upon one or more of the following grounds and no other:

Nothing contained in this section shall limit the grant of continuing jurisdiction contained in Sections 5803 to 5805, inclusive.

The petitioner for reconsideration shall be deemed to have finally waived all objections, irregularities, and illegalities concerning the matter upon which the reconsideration is sought other than those set forth in the petition for reconsideration.

A copy of the petition for reconsideration shall be served forthwith upon all adverse parties by the person petitioning for reconsideration. Any adverse party may file an answer thereto within 10 days thereafter. Such answer shall likewise be verified. The appeals board may require the petition for reconsideration to be served on other persons designated by it.

Upon the filing of a petition for reconsideration, or having granted reconsideration upon its own motion, the appeals board may, with or without further proceedings and with or without notice affirm, rescind, alter, or amend the order, decision, or award made and filed by the appeals board or the workers’ compensation judge on the basis of the evidence previously submitted in the case, or may grant reconsideration and direct the taking of additional evidence. Notice of the time and place of any hearing on reconsideration shall be given to the petitioner and adverse parties and to other persons as the appeals board orders.

If, at the time of granting reconsideration, it appears to the satisfaction of the appeals board that no sufficient reason exists for taking further testimony, the appeals board may affirm, rescind, alter, or amend the order, decision, or award made and filed by the appeals board or the workers’ compensation judge and may, without further proceedings, without notice, and without setting a time and place for further hearing, enter its findings, order, decision, or award based upon the record in the case.

Any decision of the appeals board granting or denying a petition for reconsideration or affirming, rescinding, altering, or amending the original findings, order, decision, or award following reconsideration shall be made by the appeals board and not by a workers’ compensation judge and shall be in writing, signed by a majority of the appeals board members assigned thereto, and shall state the evidence relied upon and specify in detail the reasons for the decision.

The requirements of this section shall in no way be construed so as to broaden the scope of judicial review as provided for in Article 2 (commencing with Section 5950) of this chapter.

The filing of a petition for reconsideration shall suspend for a period of 10 days the order, decision, or award affected, insofar as it applies to the parties to the petition, unless otherwise ordered by the appeals board. The appeals board upon the terms and conditions which it by order directs, may stay, suspend, or postpone the order, decision, or award during the pendency of the reconsideration.

Nothing contained in this article shall be construed to prevent the appeals board, on petition of an aggrieved party or on its own motion, from granting reconsideration of an original order, decision, or award made and filed by the appeals board within the same time specified for reconsideration of an original order, decision, or award.
