What the panel ordered
The Appeals Board denied the petition for removal filed by defendant Ace American Insurance Company from the Order of Joinder of Party Defendant.p. 3
Defendant Ace American Insurance Company filed a petition for removal from the Order of Joinder of Party Defendant issued by the WCJ on April 2, 2026, which joined Ace American in the proceedings. The WCJ filed a Report and Recommendation on Petition for Removal recommending denial of removal. The Appeals Board considered the petition and the WCJ's report and decided to deny removal.
What was disputed, and how it came out
Each issue the panel decided, with the reasoning it gave. An outcome is what this panel did on this record — not a rule, and not a prediction.
The Appeals Board denied removal because removal is an extraordinary remedy rarely exercised, requiring a showing of substantial prejudice or irreparable harm, which the petitioner did not demonstrate. The Board also noted that no record exists establishing the facts alleged by the defendant, and such issues must be decided after trial on the merits.
From the decision · page 1Defendant, Ace American Insurance Company, has filed a petition for removal from the “Order of Joinder of Party Defendant” issued on April 2, 2026, by the workers’ compensation administrative law judge (WCJ), which joined Ace American in these proceedings. Defendant contends that it is not liable for applicant’s cumulative injury and thus its joinder was not proper. We have not received an Answer from applicant. The WCJ filed a Report and Recommendation on Petition for Removal (Report) recommending that we deny removal. We have considered the allegations of the Petition for Removal and the contents of the WCJ’s Report. Based on our review of the record and based upon the WCJ’s analysis of the merits of petitioner’s arguments in the WCJ’s Report, we will deny removal. Removal is an extraordinary remedy rarely exercised by the Appeals Board. (Cortez v. Workers’ Comp. Appeals Bd.
The facts that decided it
What the panel treated as outcome-determinative, and which side it favoured.
No record exists establishing any of the facts alleged in defendant’s petition for removal.
Favours Applicant prevailed
Without a record, the Board cannot decide the merits of the petition for removal at this stage.
From the decision · page 2Code Regs., tit. 8, § 10761.) Defendant challenges its liability for cumulative injury in these proceedings, however, no record exists establishing any of the facts alleged in defendant’s petition. Absent a stipulation of the parties, such an argument can only be decided after the matter proceeds to a trial on the merits. We make no judgment at this time as to the merits of defendant’s petition as no record has been created. We would further remind defendant that in workers’ compensation proceedings: “Demurrers, petitions for judgment on the pleadings and petitions for summary judgment are not permitted.” (Cal. Code Regs., tit. 8, § 10515.) Accordingly, we deny removal.

Removal is an extraordinary remedy rarely exercised by the Appeals Board, granted only if the petitioner shows substantial prejudice or irreparable harm if removal is not granted, and that reconsideration will not be an adequate remedy if a final adverse decision issues.
The Board applied this standard to deny the petition for removal because the petitioner did not demonstrate substantial prejudice or irreparable harm, nor that reconsideration would be inadequate.
