Ismael Robledo — ADJ19112130

Defendant Ace American Insurance Company petitioned for removal from an April 2, 2026 Order of Joinder that joined Ace American as a party defendant in Ismael Robledo's cumulative injury claim. Ace American argued it was not liable for the cumulative injury and thus its joinder was improper. The WCAB denied removal, finding that no record existed to support the factual allegations in defendant's petition and that liability disputes must be resolved at trial. The Board held that defendant failed to show substantial prejudice or irreparable harm and that reconsideration would be an adequate remedy if a final adverse decision issued. The Board also reminded defendant that demurrers and summary judgment motions are not permitted in workers' compensation proceedings.
