State ex rel. Nationwide Mutual Insurance v. Henson

Summary

The Ohio Supreme Court affirmed dismissal of Nationwide Mutual Insurance Company's requests for writs of prohibition and mandamus against a common pleas judge. The court held that Nationwide had an adequate remedy through ordinary appeal and related enforcement procedures to challenge the trial court's treatment of Hamilton's reformation claim and res judicata defense. Because the trial court did not patently and unambiguously lack jurisdiction, extraordinary relief was unavailable.

Holdings

1. Neither prohibition nor mandamus will issue when the relator has an adequate remedy in the ordinary course of law, unless the lower court patently and unambiguously lacks jurisdiction.
2. Res judicata does not divest a trial court of jurisdiction to decide whether res judicata applies, and denial of a res judicata defense can be adequately challenged by post-judgment appeal.
3. Nationwide was not entitled to writs of prohibition or mandamus because Judge Henson did not patently and unambiguously lack jurisdiction over Hamilton's reformation claim and Nationwide had an adequate remedy by appeal.
4. Oral argument was not warranted because the case involved neither a matter of great public importance nor complex facts, and the parties' briefs were sufficient.

Questions Presented

1. Whether Nationwide was entitled to a writ of prohibition preventing the common pleas court from exercising jurisdiction over Hamilton's reformation claim.
2. Whether Nationwide was entitled to a writ of mandamus compelling the common pleas court to comply with the prior appellate judgments and strike or summarily dismiss Hamilton's reformation action.
3. Whether Nationwide's res judicata defense could support extraordinary relief when it could be raised through an ordinary appeal.
4. Whether oral argument was warranted.

Disposition
