Mandamus Cannot Relitigate an Unsuccessful Appeal to Enforce a Remand Absent “Direct Disobedience” of the Mandate
I. Introduction
In State ex rel. Patterson v. Starn, Slip Opinion No. 2026-Ohio-627 (Feb. 26, 2026), the Supreme Court of Ohio
affirmed the dismissal of a mandamus action brought by Cornelius Patterson Jr. (relator/appellant) against Judge Jonathan P. Starn
(respondent/appellee), a judge of the Hancock County Court of Common Pleas.
Patterson sought a writ of mandamus compelling the trial judge to “comply” with the Third District’s 2020 remand in
State v. Patterson, 2020-Ohio-1437 (“Patterson I”) by holding a second resentencing hearing and providing counsel at that hearing.
The core legal issue in the mandamus case was not the merits of Patterson’s postrelease-control complaint, but whether mandamus could be used
to enforce an appellate mandate when the relator had already pursued (and lost) the same issue by direct appeal from the post-remand trial-court action.
II. Summary of the Opinion
The court (per curiam) held that Patterson’s complaint, on its face, demonstrated he had an adequate remedy in the ordinary course of law:
he appealed the trial court’s post-remand dismissal and obtained a decision in State v. Patterson, 2021-Ohio-1237 (“Patterson II”).
Because an adequate remedy at law bars mandamus, the Third District properly dismissed the complaint under Civ.R. 12(B)(6).
The Supreme Court affirmed on that ground alone and expressly declined to decide whether the court of appeals also correctly dismissed the action
on res judicata grounds.
III. Analysis
A. Precedents Cited
1. Pleading standard on a Civ.R. 12(B)(6) motion
Relying on State ex rel. Hanson v. Guernsey Cty. Bd. of Commrs., 1992-Ohio-73 and the syllabus rule from
O'Brien v. Univ. Community Tenants Union, Inc., 42 Ohio St.2d 242 (1975), the court restated the familiar dismissal standard:
allegations are taken as true, reasonable inferences favor the nonmovant, and dismissal is proper only when it appears beyond doubt that the plaintiff
can prove no set of facts entitling relief. Review is de novo under State ex rel. Sands v. Coulson, 2021-Ohio-671.
This framing mattered because Patterson’s own allegations—particularly that he had already appealed the complained-of action—were enough to defeat
mandamus at the pleading stage.
2. The elements of mandamus and the “adequate remedy” bar
The court cited State ex. rel. Husted v. Brunner, 2009-Ohio-4805 for the three elements of mandamus:
(1) a clear legal right, (2) a clear legal duty, and (3) the lack of an adequate remedy in the ordinary course of law.
The decision turned on the third element.
3. Direct appeal is ordinarily an adequate remedy—whether used or not
The opinion reinforced that the availability of appeal generally forecloses mandamus:
State ex rel. Schneider v. N. Olmsted City School Dist. Bd. of Edn., 1992-Ohio-126, quoting
State ex rel. Cartmell v. Dorrian, 11 Ohio St.3d 177 (1984), supplies the key rule that failing to timely pursue an appeal does not make
that remedy inadequate.
Even more damaging to Patterson’s theory, the court relied on State ex rel. Nichols v. Cuyahoga Cty. Bd. of Mental Retardation & Dev. Disabilities, 1995-Ohio-215,
quoting State ex rel. Inland Properties Co. v. Eighth Dist. Court of Appeals, 151 Ohio St. 174 (1949), for the principle that mandamus will not lie
where a “plain and adequate remedy at law has been unsuccessfully invoked,” either to relitigate or as a substitute for appeal. That doctrine fit the case precisely:
Patterson invoked appeal (in Patterson II) and lost.
4. Mandamus to enforce an appellate mandate is exceptional
Patterson attempted to invoke State ex rel. Heck v. Kessler, 1995-Ohio-304 (noting the slip opinion’s headnote references “Hess,” but the body
of the opinion analyzes Heck) for the proposition that appeal may be inadequate when a lower court refuses to follow a superior court’s mandate.
The court answered with two limiting authorities:
State ex rel. Simmons v. Breaux, 2020-Ohio-3251, quoting State ex rel. Cowan v. Gallagher, 2018-Ohio-1463, which describe mandate-enforcement
mandamus as “reserved for extreme cases of direct disobedience.”
The court then distinguished Heck on its facts. In Heck, the trial judge twice dismissed a charge on unconstitutionality grounds, even after the Supreme Court
had upheld the statute and remanded for a new trial. The court in Heck held that relying solely on appeal could permit “perpetual” defiance and “repeated, ineffective appeals,”
making mandamus “the only means” to give the mandate “teeth,” quoting Hewitt v. Ryan, 356 N.W.2d 230 (Iowa 1984).
By contrast, Patterson’s own litigation history showed (1) he received appellate review of the post-remand dismissal in Patterson II, and
(2) the Third District expressly held the trial court had complied with the remand by scheduling the hearing and permitting representation.
This eliminated the “direct disobedience” concern that animated Heck.
5. Mandamus cannot serve as a “second appeal”
The court closed the loop by invoking State ex rel. Peoples v. Johnson, 2017-Ohio-9140, quoting
State ex rel. LTV Steel Co. v. Gwin, 1992-Ohio-20, reiterating that mandamus cannot be used as “a substitute for an otherwise barred second appeal”
or to obtain “successive appellate reviews of the same issue.”
B. Legal Reasoning
The opinion’s reasoning is deliberately narrow and procedural:
-
Patterson’s mandamus claim depended on proving he lacked an adequate remedy in the ordinary course of law.
-
His complaint alleged the opposite—he appealed the very action he now sought to undo via mandamus (the post-remand dismissal without the second resentencing hearing).
-
Under Nichols and Inland Properties, once a party has pursued an adequate legal remedy (even unsuccessfully), mandamus cannot be used to relitigate.
-
Patterson’s attempt to reframe the dispute as “mandate enforcement” failed because mandate-enforcement mandamus is limited to extreme, “direct disobedience” cases
(Simmons; Cowan), and the appellate court had already determined the trial court complied with the remand in the relevant sense.
-
Therefore, dismissal under Civ.R. 12(B)(6) was proper as a matter of law.
Notably, the Supreme Court did not revisit (and did not need to revisit) the underlying sentencing/postrelease-control merits or whether State v. Harper, 2020-Ohio-2913
compelled the trial court’s post-remand dismissal. It treated those questions as belonging to the completed appellate route (Patterson II), not to extraordinary writ practice.
C. Impact
-
Reinforces finality of appellate review: Litigants cannot recast an issue already litigated through appeal as a mandamus “mandate enforcement” claim merely because
they dislike the appellate outcome.
-
Clarifies the narrow scope of Heck: The decision confines State ex rel. Heck v. Kessler to situations resembling entrenched defiance that could cause
repeated interlocutory appeals without meaningful enforcement—i.e., “extreme cases of direct disobedience.”
-
Practical guidance for writ practice: To survive dismissal, a relator seeking mandate-enforcement mandamus must plead facts showing something more than alleged error;
the relator must show a qualitatively different problem—noncompliance so direct that normal appellate processes cannot provide a complete, beneficial, and speedy remedy.
-
Postrelease-control litigation remains governed by ordinary review rules: While Harper shaped the underlying procedural posture (voidable vs. void),
this case underscores that extraordinary writs will not be used to reopen those disputes once appeal has been pursued.
IV. Complex Concepts Simplified
- Mandamus
-
An extraordinary court order used to compel a public official (including a judge) to perform a clear legal duty.
It is not a general-purpose error-correction tool and is unavailable when ordinary legal remedies (like appeal) suffice.
- Adequate remedy in the ordinary course of law
-
A legal path—typically appeal—that can address the claimed error. If that path exists, mandamus is usually barred.
If the path is used and fails, mandamus still cannot be used to try again.
- Mandate / law-of-the-case
-
A mandate is an appellate court’s directive to the lower court after an appeal. The law-of-the-case doctrine generally requires the lower court to follow
the appellate court’s legal determinations on remand. But if intervening higher authority changes controlling law, ordinary appellate review—rather than mandamus—typically addresses disputes.
- Res judicata
-
A final-judgment rule barring relitigation of matters that were or could have been raised previously. The court did not decide this issue because the adequate-remedy bar was enough to affirm.
- Void vs. voidable sentencing error (postrelease control)
-
After State v. Harper, 2020-Ohio-2913, certain postrelease-control mistakes render a judgment “voidable” (correctable only through normal procedures like timely appeal),
not “void” (subject to collateral attack at any time). This shift explains why Patterson’s resentencing trajectory changed midstream, but it did not expand mandamus availability.
V. Conclusion
State ex rel. Patterson v. Starn cements a practical boundary: when a relator has already challenged the complained-of post-remand action through direct appeal,
mandamus cannot be used to obtain a do-over— even when framed as enforcing an appellate mandate. Only “extreme cases of direct disobedience” fall within the narrow Heck-type
exception. The decision strengthens finality, channels most mandate disputes back into the appellate process, and limits extraordinary writs to truly extraordinary circumstances.
