Summary

Applicant Leigh Jeffrey filed multiple claims for asbestos and dust exposure injuries, including COPD, across two case numbers (ADJ9507100 and ADJ11097936). The parties settled the asbestos claim (ADJ9507100) via a 2020 Compromise and Release that listed only that case number. Liberty Mutual sought to dismiss the second case (ADJ11097936) as duplicative, and the WCJ found res judicata barred the COPD lung injury claim. On reconsideration, the Board held that no medical evidence was produced to determine whether the COPD fell within the settled asbestos claim or constituted a separate injury caused by other industrial exposures. The Board granted reconsideration, rescinded the April 14, 2026 F&O, and returned the matter to the trial level for further proceedings to develop the medical record.
