Summary

Applicant Daniel Mendez Castillo claimed an industrial injury to his right eye on September 23, 2022, while employed as a sanitation worker for Better Nutritionals, LLC. After State National Insurance Company (insurer for the alleged general/PEO employer) was previously dismissed without prejudice on March 13, 2024 pursuant to stipulation, Technology Insurance Company (AmTrust) petitioned to rejoin State National based on newly discovered evidence of a certificate of liability insurance. The WCJ issued an Order of Joinder on May 21, 2025, and State National sought reconsideration/removal arguing collateral estoppel/res judicata. The Board granted reconsideration, finding the joinder void ab initio due to defective service and an inadequate record, and that the dismissal stipulation was 'without prejudice' rather than with prejudice. The Board rescinded both the May 21, 2025 Order of Joinder and the March 13, 2024 Order of Dismissal, and returned the matter to the trial level to develop an adequate record.
