State ex rel. Awms Water Solutions, L.L.C. v. Mertz

Summary

The Ohio Supreme Court held that the suspension of AWMS’s saltwater‑injection wells did not constitute a total regulatory taking because AWMS failed to show deprivation of all economically beneficial use, and it also reversed the appellate court’s finding of a compensable partial regulatory taking after re‑balancing the Penn Central factors. The Court affirmed the appellate judgment on the total‑taking claim, reversed it on the partial‑taking claim, and denied the writ of mandamus.
