Background

David McCartney sustained a work-related injury in 2001 while employed by Simco Management, Inc. Although his claim was allowed for various injuries and he received permanent-partial-disability compensation, the Industrial Commission denied three applications for permanent-total-disability compensation, most recently in 2023. The commission concluded that his third application did not establish the new and changed circumstances required for a subsequent PTD application.

McCartney sought mandamus relief in the Tenth District Court of Appeals. In March 2025, the court granted a writ requiring the commission to vacate its 2023 order and conduct further proceedings, finding that McCartney had cleared the threshold for consideration of his application’s merits. The commission later learned that McCartney had died in January 2024, before the writ issued, and moved to vacate the judgment. The Tenth District denied that motion, reasoning that it retained subject-matter jurisdiction and its judgment was not void.

The Court’s Holding

The Supreme Court of Ohio held that McCartney’s PTD claim abated upon his death and that his related mandamus action therefore became moot. Because the claim was extinguished, the commission could not grant the requested relief, and a writ directing further proceedings would compel a vain act.

The court rejected the commission’s argument that the Tenth District’s March 2025 judgment was void for lack of subject-matter jurisdiction. The court of appeals retained constitutional authority over mandamus actions; abatement and mootness affected its ability to grant relief, not its subject-matter jurisdiction. But vacatur was equitable and appropriate because the case became moot through happenstance before the writ issued, without fault by the commission. The court reversed and remanded with instructions to vacate the earlier writ and dismiss the action as moot.

Key Takeaways

  • A claimant’s pending application for PTD compensation abates upon the claimant’s death.
  • Abatement can moot a related workers’ compensation mandamus action, even though the appellate court retains subject-matter jurisdiction over mandamus cases.
  • When mootness arises through happenstance and prevents merits review, vacatur of the lower court’s judgment may be the appropriate equitable remedy.

Why It Matters

The decision distinguishes a court’s jurisdiction to hear a class of cases from its authority to award effective relief in a particular moot dispute. It also confirms that a deceased claimant’s estate or dependents cannot continue the claimant’s own PTD claim through mandamus after the claim has abated.
