How the appealed decisions came out

These are decisions that were appealed and published — the tail of a system that mostly settles. Most claims end in a compromise and release or a stipulation and never reach a panel, so nothing below describes how this insurance carrier does its work. It describes how a set of appealed disputes came out.

• ADJ15039687 · 2025-10-24 · Oakland District OfficeReconsideration / removaldefendant prevailed

  Determinative passage · p.2substantial prejudice or irreparable harm will result if removal is not granted. (Cal. Code Regs., tit. 8, 10955(a); see also Cortez, supra; Kleemann, supra.) Also, the petitioner must demonstrate that reconsideration will not be an adequate remedy if a final decision adverse to the petitioner ultimately issues. (Cal. Code Regs., tit. 8, § 10955(a).) Here, defendant has not established substantial prejudice or irreparable harm if applicant is permitted to subpoena a copy of her own medical files. As noted by the WCJ, any issue as to whether such a cost is a reasonable litigation expense is deferred.

  Defendant did not establish substantial prejudice or irreparable harm if the subpoena for applicant's medical records was not quashed, and reconsideration was deemed an adequate remedy if a final adverse decision issued.

• ADJ12765398 · 2023-09-01 · Oakland District OfficeReconsideration / removaldefendant prevailed

  Determinative passage · p.1Removal is an extraordinary remedy rarely exercised by the Appeals Board. (Cortez v. Workers' Comp. Appeals Bd. (2006) 136 Cal.App.4th 596, 599, fn. 5 [71 Cal.Comp.Cases 155]; Kleemann v. Workers' Comp. Appeals Bd. (2005) 127 Cal.App.4th 274, 280, fn. 2 [70 Cal.Comp.Cases 133].) The Appeals Board will grant removal only if the petitioner shows that substantial prejudice or irreparable harm will result if removal is not granted. (Cal. Code Regs., tit. 8, § 10955(a); see also Cortez, supra; Kleemann, supra.) Also, the petitioner must demonstrate that reconsideration will not be an adequate remedy if a final decision adverse to the petitioner ultimately issues. (Cal. Code Regs., tit. 8, § 10955(a).) Here, based upon the WCJ's analysis of the merits of petitioner's arguments, we are not persuaded that substantial prejudice or irreparable harm will result if removal is denied and/or that reconsideration will not be an adequate remedy if the matter ultimately proceeds to a final decision adverse to petitioner.

  The Appeals Board denied removal because the petitioner did not show substantial prejudice or irreparable harm if removal was denied, nor that reconsideration would be inadequate if the matter proceeded to a final adverse decision.

The Appeals Board will grant removal only if the petitioner shows that substantial prejudice or irreparable harm will result if removal is not granted. (Cal. Code Regs., tit. 8, former § 10843(a), now § 10955(a) (eff. Jan. 1, 2020); see also Cortez, supra; Kleemann, supra.) Also, the petitioner must demonstrate that reconsideration will not be an adequate remedy if a final decision adverse to the petitioner ultimately issues. (Cal.

Here, based upon the WCJ's analysis of the merits of petitioner's arguments, we are not persuaded that substantial prejudice or irreparable harm will result if removal is denied and/or that reconsideration will not be an adequate remedy if the matter ultimately proceeds to a final decision adverse to petitioner.

  Petitioner failed to show substantial prejudice or irreparable harm if removal was denied and failed to show reconsideration would be inadequate remedy.
