Senior Helpers; Endurance Insurance, administered by First Comp Eleanor Castillo WORKERS’ COMPENSATION APPEALS BOARDSTATE OF CALIFORNIAELEANOR CASTILLO, ADJ6590824, Applicant,vs.SENIOR HELPERS; ENDURANCE INSURANCE, administered by FIRST COMP, Defendants.Case Nos. ADJ6590798 (Pomona District Office)OPINION AND ORDER GRANTING PETITION FOR RECONSIDERATION Reconsideration has been sought by defendant Endurance Insurance Company, and its administrator First Comp with regard to a decision issued by a workers’ compensation administrative law judge on December 27, 2012. Taking into account the statutory time constraints for acting on the petition, and based upon our initial review of the record, we believe reconsideration must be granted in order to allow sufficient opportunity to further study the factual and legal issues in this case. We believe that this action is necessary to give us a complete understanding of the record and to enable us to issue a just and reasoned decision. Reconsideration will be granted for this purpose and for such further proceedings as we may hereinafter determine to be appropriate. Lien claimant Mumtaz Ali, M.D., filed an Answer on February 22, 2012 to defendant’s Petition for Reconsideration. On March 14, 2013, defendant sought permission to file a supplemental response to the Answer to respond to new issues raised by lien claimant in the Answer that were not raised at trial. Under Appeals Board Rule 10848, the Appeals Board has discretion to approve the filing of supplemental pleadings. (Cal. Code Regs., tit. 8, § 10848.) Here, defendant sought reconsideration on the issue of the denial of its request for reasonable expenses and sanctions against lien claimant. (Lab. Code, § 5813; Cal. Code Regs., tit. 8, 10561.) We believe that in order to fully develop the record, it is , necessary to grant defendant’s request to file a supplemental response. (See Evans v. Workmen’s Comp. Appeals Bd. (1968) 68
