{¶ 1} In 1996, Kimberly Johnson retained appellant, Marshall D. Buck, an attorney licensed to practice law in Ohio, to represent her in matters relating to the death of her husband, Alan J. Withers. During his representation of Johnson, Buck settled a wrongful-death claim without the approval of the Mahoning County Court of Common Pleas, Probate Division. Buck’s wife, attorney JeÁnne Longenhagen,
{¶ 2} On October 8, 2002, appellee, Judge Timothy P. Maloney of the probate court, found that both Buck and Longenhagen had “hindered, delayed, and obstructed the administration of’ several estates, including the Withers estate. Judge Maloney concluded that Buck’s settling the wrongful-death claim without court approval had been “plainly unlawful as contrary to O.R.C. Chapter 2125, Superintendence Rules 70 and 71 and various of the Local Rules of [the Mahoning County Probate] Court.” Based on his findings, Judge Maloney removed Longenhagen from the Withers estate case and barred Buck and Longenhagen from serving as counsel in any new proceeding in the probate court:
{¶ 3} “IT IS THEREFORE ORDERED, ADJUDGED AND DECREED that Attorney JeAnne Longenhagen be and is hereby Ordered REMOVED as Counsel of Record in each and all of these cases and any related proceedings and,
{¶ 4} On December 13, 2002, Buck filed a complaint in the Court of Appeals for Mahoning County. Buck sought a writ of prohibition to prevent Judge Maloney from barring him from practicing law in the probate court. In March 2003, Judge Maloney moved to dismiss Buck’s prohibition complaint for failure to state a claim upon which relief can be granted. See Civ.R. 12(B)(6). After Buck responded, the court of appeals granted Judge Maloney’s motion and dismissed the prohibition complaint under Civ.R. 12(B)(6).
{¶ 5} This cause is now before this court upon Buck’s appeal as of right.
{¶ 6} Buck asserts that the court of appeals erred in dismissing his prohibition action. The Civ.R. 12(B)(6) dismissal of Buck’s prohibition complaint for failure to state a claim upon which relief can be granted was justified if, after presuming the truth of all factual allegations of the complaint and making all reasonable inferences in Buck’s favor, it appeared beyond doubt that Buck could prove no set of facts entitling him to the requested extraordinary writ of prohibition. See State ex rel. Conkle v. Sadler,
{¶ 7} Applying this standard to Buck’s claim, we hold that Buck’s prohibition claim is meritorious. Section 5(A)(1), Article IV of the Ohio Constitution grants this court general supervisory power over the courts of Ohio, and we have “guarded our general supervisory power over the court system from encroachment by the lower courts.” State v. Steffen (1994),
{¶ 9} Similarly, in State ex rel. Jones v. Stokes (1989),
{¶ 10} “Certainly, this broad sanction goes beyond disqualification or mere regulation of the conduct of counsel in a particular proceeding. Respondents have imposed a continuing restriction on [the attorney’s] ability to practice law in their two courtrooms. This restriction differs only by degree from the sanctions imposed through the grievance procedures which are supervised by the Supreme Court of Ohio. Yet, the Supreme Court’s ‘jurisdiction over the discipline of attorneys * * * is exclusive and absolute.’ Smith v. Kates (1976),
{¶ 11} Based on the foregoing precedent, Judge Maloney acted without jurisdiction by prohibiting Buck from practicing law in “any new case or proceeding” before the probate court.
{¶ 12} The court of appeals relied on Sup.R. 78(D) to conclude that Judge Maloney did not patently and unambiguously lack jurisdiction to issue the order barring Buck from practicing law in the probate court. This reliance, however, is misplaced. Sup.R. 78(D) authorizes probate courts to bar attorneys from repre
{¶ 13} “The court may issue a citation to the attorney of record for a fiduciary who is delinquent in the filing of an inventory, account, or guardian’s report to show cause why the attorney should not be barred from being appointed in any new proceeding before the court or serving as attorney of record in any new estate, guardianship, or trust until all of the delinquent pleadings are filed.” (Emphasis added.)
{¶ 14} Buck was not the attorney of record for a fiduciary who was delinquent in filing probate pleadings, and Judge Maloney did not restrict his order to end when delinquent pleadings were filed. Instead, Judge Maloney’s order barred Buck from representing clients in future proceedings before the probate court “until further Order of the Court.”
{¶ 15} Judge Maloney’s reliance on State ex rel. Kura v. Sheward (1992),
{¶ 16} Therefore, after construing the material factual allegations of Buck’s complaint and all reasonable inferences therefrom in his favor, Buck’s prohibition complaint may have merit. He may ultimately be able to establish that Judge Maloney patently and unambiguously lacked jurisdiction to bar him from future probate proceedings. “[I]f an inferior court ‘patently and unambiguously lacks jurisdiction over the cause, prohibition will lie both to prevent the future unauthorized exercise of jurisdiction and to correct the results of previous jurisdictionally unauthorized actions.’ ” (Emphasis sic.) State ex rel. Sartini v. Yost,
{¶ 17} Thus, the court of appeals erred in dismissing Buck’s complaint for a writ of prohibition. “ ‘Generally, reversal of a court of appeals’ erroneous dismissal of a complaint based upon failure to state a claim upon which relief can be granted requires a remand [to that court] for further proceedings.’ ” State ex rel. Rogers v. McGee Brown (1997),
{¶ 18} Accordingly, we reverse the judgment of the court of appeals and grant the requested writ of prohibition. Costs are taxed to appellee.
Judgment reversed and writ granted.
