IN PROHIBITION.

Per Curiam.

{¶ 1} Petitioner, John Durkin, executor of the estate of Virginia Durkin, 

seeks a writ of prohibition against respondent, Judge Steven O. Williams, who is

presiding over the underlying action involving the Durkin estate in the Summit 

County Common Pleas Court, Probate Division. John contends that Judge 
SUPREME COURT OF OHIO

Williams’s appointment of a special master commissioner under R.C. 2101.06 

disregards the law of the case established in In re Estate of Durkin, 9th Dist. Summit 

No. 28661, 2018-Ohio-2283 (“Durkin I”). John attempted to appeal the order 

appointing the special master commissioner, but the court of appeals dismissed the 

appeal for lack of a final, appealable order. In re Estate of Durkin, 9th Dist. Summit 

No. 29532, 2021-Ohio-1076 (“Durkin II”). John then brought the present original 

action.

{¶ 2} We denied Judge Williams’s motion to dismiss and granted an 

alternative writ. 164 Ohio St.3d 1437, 2021-Ohio-3233, 173 N.E.3d 1219. For the 

reasons set forth below, we now deny the writ.

I. FACTS

{¶ 3} In August 2015, Virginia Durkin died a resident of Summit County. 

Virginia’s daughter, Patricia O’Halloran, predeceased her by several months. 

Virginia’s will provided for her estate to be divided equally between her children, 

Patricia and John; if Patricia predeceased Virginia, then Patricia’s share would pass 

to her three children per stirpes. See Durkin I at ¶ 2. The will was admitted to 

probate, and John was appointed as the executor in accordance with the will.

{¶ 4} The administration of the estate became contentious when Patricia’s 

son, Daniel O’Halloran, contended that John had abused his power of attorney 

while Virginia was alive and that he had not included assets in the estate inventory

that should have been included. A brief overview of the probate proceedings is 

necessary to understand John’s prohibition claim.

A. Inventory, objections, and final judgment

{¶ 5} John filed the estate inventory in October 2015, and the probate court 

approved it in December 2015. The inventory listed $503,320 worth of savings 

bonds as the sole asset of the estate. In May and June 2016, Daniel submitted 

untimely objections to the inventory as well as objections to the estate’s final 

account.
January Term, 2022

3

{¶ 6} In August 2016, the probate-court magistrate held a hearing on 

Daniel’s objections, and at that hearing, Daniel contended that John had engaged 

in fraud and self-dealing in his roles as attorney in fact for Virginia and executor of 

her estate. Daniel later obtained information regarding assets that he believed 

should have been included in the estate, and the magistrate ordered disclosures 

regarding two individual retirement accounts (“IRAs”) Virginia had held.

{¶ 7} In February 2017, the magistrate issued a decision disposing of (1) 

Daniel’s exceptions to the inventory and accounting, (2) Daniel’s motion to remove 

John as executor, and (3) various other motions and objections. With respect to 

one IRA, the magistrate found that John had engaged in self-dealing when, after 

Patricia’s death, he used his power of attorney to substitute himself for Patricia as 

beneficiary. Based on that finding, the magistrate set aside the substitution and 

ordered that the IRA be included in the estate. With respect to one of Virginia’s 

bank accounts, the magistrate imposed a constructive trust on one-half of that 

account because the funds were traceable to a certificate of deposit that had 

designated Patricia as a beneficiary—the magistrate ordered that that portion be 

included in the estate. With respect to the savings bonds, the magistrate upheld 

their inclusion in the estate, rejecting Daniel’s contention that they ought to have 

been re-registered with him and his siblings as beneficiaries. The magistrate also 

reduced a fine for a contempt citation against Daniel to $500. In all other respects, 

the magistrate rejected Daniel’s contentions.

{¶ 8} Daniel filed objections to the magistrate’s decision. In May 2017, the 

probate court issued a final judgment entry overruling the objections and adopting 

the magistrate’s decision. The entry specifically stated: (1) “John remains as 

Executor” and (2) “[t]he Court accepts the Estate Accounting.” The court also 

denied Daniel’s motions objecting to the payment of John’s fiduciary fees as 

executor and the estate attorney’s fees, sustained the finding of contempt against 

Daniel, and stated that there was “no just cause for delay.”
SUPREME COURT OF OHIO

B. Durkin I

{¶ 9} Daniel appealed the final judgment, and in June 2018, the court of 

appeals affirmed in part and reversed in part the probate court’s order. Durkin I, 

2018-Ohio-2283. The appellate court reversed the contempt finding against Daniel, 

id. at ¶ 39-40, 44, but it rejected Daniel’s seven other assignments of error. The 

court of appeals remanded for further proceedings “consistent with” its decision.

Id. at ¶ 44. The court of appeals also ordered that a special mandate issue requiring 

the trial court to carry the appellate court’s judgment into execution.

C. Proceedings after remand

{¶ 10} On remand, the probate-court magistrate issued an order in January

2019 that (1) vacated the contempt finding against Daniel and (2) required John to 

file an amended inventory reflecting the magistrate’s rulings that had been adopted 

in the probate court’s May 2017 final judgment entry. John duly filed the amended 

inventory, and Daniel filed objections. Daniel also sought to disqualify the probatecourt judge—Judge Elinore Marsh Stormer—on grounds of bias. Although the 

judge denied any bias, she voluntarily recused herself, and Judge Williams was 

assigned to the case.

{¶ 11} At an April 2019 status conference, Judge Williams expressed an 

“inclination” to remove John as executor. But after holding a hearing on the 

removal issue, Judge Williams declined to remove John as executor. Instead, in 

August 2019, Judge Williams appointed a special master commissioner, in 

accordance with R.C. 2101.06, and instructed that commissioner to “investigate and 

make a report to the [Probate] Court as to whether any additional assets should be 

included in the [estate] after examining the actions of John Durkin acting with the 

Power of Attorney from Virginia Durkin.”

D. Durkin II

{¶ 12} John attempted to appeal the August 2019 order appointing the 

special master commissioner, arguing that it violated the mandate from the earlier 
January Term, 2022

5

appeals-court decision with respect to the disposition of several of Daniel’s 

assignments of error. In March 2021, the court of appeals dismissed for lack of a 

final, appealable order. Durkin II, 2021-Ohio-1076.

{¶ 13} One judge dissented, stating that she would conclude that the order 

was final and appealable; she also stated: “Perhaps an appropriate remedy under 

these circumstances would be for [John] to file an action requesting an 

extraordinary writ, given that he contends that the visiting judge disregarded this 

Court’s prior decision.” Id. at ¶ 14 (Carr, J., dissenting).

{¶ 14} In May 2021, John filed this action seeking a writ of prohibition.

II. ANALYSIS

A. Law of the case and the remedy of prohibition

{¶ 15} Generally, to demonstrate entitlement to a writ of prohibition, a 

petitioner must show (1) that a court has exercised judicial power, (2) that its 

exercise of judicial power is unauthorized by law, and (3) that denying the writ 

would result in injury for which no other adequate remedy exists in the ordinary 

course of law. See State ex rel. Greene Cty. Bd. of Commrs. v. O’Diam, 156 Ohio 

St.3d 458, 2019-Ohio-1676, 129 N.E.3d 393, ¶ 16. But a petitioner does not need 

to prove the third requirement—the lack of an adequate remedy in the ordinary 

course of law—if he can show that the court patently and unambiguously lacked 

jurisdiction to exercise its judicial power as it did. Id. at ¶ 26. This exception from 

the general rule comes into play in this case because the availability of a 

discretionary appeal from Durkin II (which John did not pursue) qualifies as an

adequate remedy in the ordinary course of law, even though this court might have 

denied jurisdiction. See State ex rel. O’Malley v. Collier-Williams, 153 Ohio St. 

553, 2018-Ohio-3154, 108 N.E.3d 1082, ¶ 14-15. Therefore, to be entitled to the 

requested writ, John must show that Judge Williams patently and unambiguously

lacked jurisdiction to appoint a special master commissioner in the underlying case.
SUPREME COURT OF OHIO

{¶ 16} John predicates his prohibition claim on Judge Williams’s alleged

“fail[ure] to comply with the appellate court’s mandate directed to [the probate] 

court.” He asserts that because “the appellate court’s decision in [Durkin I, 2018-

Ohio-2283,] is the law of this case,” it “governs any other court which subsequently 

considers this case.” The law-of-the-case doctrine states that “[a]bsent 

extraordinary circumstances, such as an intervening decision by the Supreme Court, 

an inferior court has no discretion to disregard the mandate of a superior court in a 

prior appeal in the same case.” Nolan v. Nolan, 11 Ohio St.3d 1, 462 N.E.2d 410 

(1984), syllabus. Equally established is the principle that “ ‘a writ of prohibition is 

an appropriate remedy to prevent a lower court from proceeding contrary to the 

mandate of a superior court.’ ” State ex rel. Cordray v. Marshall, 123 Ohio St.3d 

229, 2009-Ohio-4986, 915 N.E.2d 633, ¶ 32, quoting State ex rel. Crandall, Pheils 

& Wisniewski v. DeCessna, 73 Ohio St.3d 180, 182, 652 N.E.2d 742 (1995).

{¶ 17} Although it is settled that the law-of-the-case doctrine may furnish 

the grounds for a writ of prohibition in a proper case, the court adjudicating the 

prohibition claim must determine whether the challenged action of the trial court in 

fact violates the earlier appeals-court mandate or whether the action fell within the 

lower court’s residual powers. The appellate court’s mandate establishes the law

of the case on the legal questions involved in that appeal, State ex rel. Baker v. State 

Personnel Bd. of Rev., 85 Ohio St.3d 640, 642, 710 N.E.2d 706 (1999), meaning 

that the law-of-the-case doctrine “ ‘comes into play only with respect to issues 

previously determined,’ ” Giancola v. Azem, 153 Ohio St.3d 594, 2018-Ohio-1694, 

109 N.E.3d 1194, ¶ 16, quoting Quern v. Jordan, 440 U.S. 332, 347, 99 S.Ct. 1139, 

59 L.Ed.2d 358 (1979), fn. 18. Additionally, the law-of-the-case doctrine will not 

be applied to achieve unjust results. See Baker at 643.

B. The appellate court’s pronouncement in Durkin II

regarding the mandate in Durkin I is not dispositive

{¶ 18} In the context of dismissing John’s appeal from Judge Williams’s

order appointing the special master commissioner, the appellate court stated: “We 

find nothing * * * in the mandate of the prior order of this Court that would conflict 

with appointment of a master commissioner by the trial court.” Durkin II, 2021-

Ohio-1076, at ¶ 10. Citing this pronouncement, Judge Williams argues that because 

the court of appeals “took no offense to [his] actions in hiring a Master 

Commissioner,” it is “inappropriate for [John] to obtain another ‘bite at the apple’ 

via this Writ of Prohibition.”

{¶ 19} In the past, we have shown deference to appellate courts when those 

courts have determined the scope of their own mandate. Observing that the court 

of appeals is in the best position to determine whether a trial court has violated the 

appellate court’s mandate, this court has declined to find a patent and unambiguous 

lack of jurisdiction by the trial court when the court of appeals itself has found no 

violation of its mandate. State ex rel. Pyle v. Bessey, 112 Ohio St.3d 119, 2006-

Ohio-6514, 858 N.E.2d 383, ¶ 12; see also State ex rel. Jelinek v. Schneider, 127 

Ohio St.3d 332, 2010-Ohio-5986, 939 N.E.2d 847, ¶ 14; but see State ex rel. 

Mullins v. Curran, 131 Ohio St.3d 441, 2012-Ohio-685, 966 N.E.2d 267, ¶ 10, 12 

(reversing court of appeals’ decision granting a writ of prohibition to prevent a trialcourt judge from conducting a retrial on the claim of negligence, which the court 

of appeals held was in violation of its earlier mandate).

{¶ 20} In this case, however, we decline to defer to the court of appeals’

pronouncement. In Durkin II, the appellate court dismissed John’s appeal because 

it found that Judge Williams’s order appointing the special master commissioner 

was not a final, appealable order. The only issue relevant to making that 

determination in Durkin II was whether John could effectively protect his right to 

enforce the mandate in a later appeal from a later order. Id. at ¶ 6. The violation-
SUPREME COURT OF OHIO

8

of-mandate issue was not a basis for the court of appeals’ decision that the order 

was not final and appealable but instead constituted the substantive issue raised by 

John’s premature appeal.

{¶ 21} By concluding that the order was not appealable, the court of appeals 

effectively ruled that it had no jurisdiction to decide whether the mandate had been 

violated. As a result, the appellate court’s substantive finding that the mandate had 

not been violated was a nullity. See Supportive Solutions, L.L.C. v. Electronic 

Classroom of Tomorrow, 137 Ohio St.3d 23, 2013-Ohio-2410, 997 N.E.2d 490, 

¶ 10 (“An appellate court can review only final orders, and without a final order, an 

appellate court has no jurisdiction”); State v. Henderson, 161 Ohio St.3d 285, 2020-

Ohio-4784, 162 N.E.3d 776, ¶ 17 (a judgment rendered by a court without 

jurisdiction “is a mere nullity”). We must therefore make an independent 

determination concerning the scope of the mandate.

C. Whether appointing the special master commissioner

violated the Durkin I mandate

{¶ 22} The first step in evaluating John’s prohibition claim consists of

closely inspecting his argument that appointing the special master commissioner 

violated the appellate court’s mandate in Durkin I, 2018-Ohio-2283. Although 

John attaches some importance to the court of appeals’ affirmance of Judge 

Williams’s decision not to remove him as executor, his main argument for finding 

a violation of the mandate lies in his observation that Durkin I “affirmed the probate 

court’s determination to close the record” by “overrul[ing] [Daniel’s] third and fifth 

assignments of error.”

{¶ 23} John’s characterization of the probate court’s rulings, which were 

affirmed by the court of appeals in Durkin I, is correct: the probate court initially 

made rulings on the information before it, cut off further investigation, and all of 

its rulings merged into the final judgment that was affirmed in pertinent part by the 

court of appeals. See Navistar, Inc. v. Testa, 143 Ohio St.3d 460, 2015-Ohio-3283, 
January Term, 2022

9

39 N.E.3d 509, ¶ 38 (“the [Board of Tax Appeals] hearing examiner’s [evidentiary] 

ruling has merged into the BTA’s decision and constitutes the law of this case, 

subject to challenge * * * in this appeal”). Specifically, the court of appeals 

affirmed the probate court’s order terminating further discovery when it overruled 

two of Daniel’s assignments of error. In overruling Daniel’s third assignment of 

error, the court of appeals held that the probate court did not abuse its discretion 

when it denied Daniel’s motion to compel discovery of information about John’s 

alleged abuse of his power of attorney before Virginia’s death. Durkin I at 

¶ 16-19. And in overruling Daniel’s fifth assignment of error, the appeals court 

held that the probate court did not abuse its discretion by “entering judgment on the 

accounting of Virginia Durkin’s estate and denying [Daniel] a hearing despite his 

presentation of new evidence in his objections to the magistrate’s decision.” Id. at 

¶ 25.

{¶ 24} Accordingly, John presents a plausible argument that when, after 

remand, Judge Williams ordered an investigation into John’s actions, he reopened

what the probate court had fully resolved in the earlier proceedings and thus

violated the law-of-the-case doctrine because the probate court’s rulings had been 

affirmed by the court of appeals and were thereby incorporated into the appellate 

court’s mandate.

{¶ 25} But the mere plausibility of John’s argument is not a sufficient basis 

for a writ of prohibition to issue. The necessary second step in evaluating John’s 

prohibition claim involves determining whether his argument so clearly establishes 

a violation of the mandate that Judge Williams’s lack of jurisdiction was patent and 

unambiguous. See Mullins, 131 Ohio St.3d 441, 2012-Ohio-685, 966 N.E.2d 267, 

¶ 11. Because Mullins involved this court’s independent determination whether an 

appeals court’s mandate was violated, it provides us with guidance in deciding this 

case.
SUPREME COURT OF OHIO

10

{¶ 26} In Mullins, the estate administrator brought a medical-malpractice 

action to recover damages in connection with the decedent’s death. A jury returned 

a finding of negligence and awarded damages, and the defendants appealed. In 

pertinent part, the defendants argued that the trial court erred by failing to instruct 

the jury on the possible contributory negligence of the estate administrator herself. 

The Seventh District Court of Appeals held that the trial court erred in failing to 

give that instruction and in denying the defendants’ motion for a new trial. Mullins 

v. Comprehensive Pediatric & Adult Medicine, Inc., 7th Dist. Mahoning No. 07 

MA 144, 2009-Ohio-1310, ¶ 74, 79, 81-82, 86, 87, 91, 102. On remand, the trial 

court set the case for retrial on both the negligence claim and the contributorynegligence issue. The estate administrator objected, asserting that the retrial should 

address only the issue of contributory negligence.

{¶ 27} When the trial judge persisted, the estate administrator brought a 

prohibition action in the court of appeals. The appellate court held that retrying the 

negligence claim would violate its earlier mandate, and it therefore granted the writ. 

State ex rel. Mullins v. Curran, 7th Dist. Mahoning No. 10 MA 76, 2011-Ohio1312. But on appeal, we reversed, holding that the trial-court judge “reasonably 

concluded from the court of appeals’ mandate * * * that a retrial of the wrongfuldeath case, including the negligence claim * * * was warranted.” Mullins, 131 Ohio 

St.3d 441, 2012-Ohio-685, 966 N.E.2d 267, ¶ 10. We observed: “The court of 

appeals’ mandate does not expressly restrict or otherwise limit the new trial to the 

contributory-negligence issue” and does not “specifically limit the retrial so as to 

preclude the jury’s consideration of the negligence claim.” Id. at ¶ 10, 12.

{¶ 28} Mullins provides the test that we will use in this case: Did Durkin I, 

2018-Ohio-2283, “expressly restrict” and “specifically limit the [proceedings]” on 

remand in a manner that precluded Judge Williams’s appointment of the special 

master commissioner to investigate Durkin’s use of the power of attorney? The 

answer is no. Any such restriction is at best implied, which is insufficient. Because 
January Term, 2022

11

Durkin I did not clearly and explicitly restrict the probate court’s actions on remand 

regarding John’s use of the power of attorney, Judge Williams did not patently and 

unambiguously lack jurisdiction to appoint the special master commissioner to 

conduct further investigation.

{¶ 29} Mullins also makes an important point concerning the need for an 

appellate-court mandate to be sufficiently clear. If a court of appeals’ order 

explicitly limits the trial court’s jurisdiction on remand, it enables the party 

aggrieved by the limitation to appeal that ruling. In Mullins, if the original court of 

appeals’ decision had explicitly ordered that the new trial address only contributory 

negligence, the defendants could have appealed that limitation. Mullins at ¶ 13. 

Similarly, if Durkin I had clearly and explicitly forbidden further investigation of 

John’s use of the power of attorney on remand, Daniel could have appealed that 

ruling. As in Mullins, we adhere in this case to the principle that the law-of-thecase doctrine will not be applied to achieve an unjust result. Id. at ¶ 14.
