State ex rel. Schwarzmer v. Mazzone

Summary

The Ohio Supreme Court reversed the Eighth District Court of Appeals and denied writs of prohibition and mandamus, holding that the Cuyahoga County Court of Common Pleas did not lack subject‑matter jurisdiction over the declaratory‑judgment claim and that an appeal provides an adequate remedy. The Court emphasized that a court’s inability to void another court’s judgment does not divest its general jurisdiction, and that the availability of appellate review forecloses extraordinary relief.
