If a final judgment of a court of competent jurisdiction reverses or declares invalid a precedent decision of the appeals board issued under Section 409 or this section, the appeals board, acting as a whole, shall promptly modify the precedent decision to conform in all respects to the judgment of the court. The modified precedent decision shall supersede the prior precedent decision for all purposes. The appeals board shall promptly notify the director, the administrative law judges of the appeals board, and all other subscribers to the precedent decisions, of the modified precedent decision.
