To obtain a writ of prohibition, Sellers was required to establish (1) that appellees were about to exercise judiciаl or quasi-judicial power, (2) that the exercise of that power was unauthorized by law, and (3) that denying the writ would result in injury for which no other adequate remedy existed in the ordinary course of law. State ex rel. Fowler v. Smith (1994),
Sellers asserts, in his first and second propositions of law that appellees lacked jurisdiction over the defamation claim, since the Franklin County Common Pleas Court had exсlusive jurisdiction over that action as well as other conduct arising out of attorneys Foley and Steele’s representation of Sellers in his disciplinary proceeding and administrative appeals.
“ ‘As between [state] courts of conсurrent jurisdiction, the tribunal whose power is first invoked by the institution of proper proceedings acquires jurisdiction to the exсlusion of all other tribunals, to adjudicate upon the whole issue and to settle the rights of the parties.’ ” State ex rel. Racing Guild of Ohio v. Morgan (1985),
In general, it is a condition of the operation of the state jurisdictional priority rule that the claims or causes of аction be the same in both cases, and “[i]f the second case is not for the same cause of action, nor between the same parties, the former suit will not prevent the latter.” State ex rel. Judson v. Spahr (1987),
Nevertheless, we have at times recognized the applicability of the priority rule where the causes of action and relief requested are not exactly the same. See, e.g., State ex rel. Phillips (actions for damages and for resсission based on same realty purchase contract [see Ohio Supreme Court Records and Briefs, 3d Series, casе No. 76-994]), and Weenink & Sons (actions for damages and declaratory judgment based on same rodeo proceeds), supra. In contrast to these exceptions to the general rule, it is not clear here that the two suits comprise part of the same “whоle issue.”
The elements of a legal malpractice action are (1) an attorney-client relationship giving rise tо a duty, (2) a breach of that duty, and (3) damages proximately caused by the breach. Krahn v. Kinney (1989),
“ ‘Absent a patent and unambiguous lack of jurisdiction, a court having general jurisdiction of the subjеct matter of an action has authority to determine its own jurisdiction. A party challenging the court’s jurisdiction has an adequаte remedy at law via appeal from the court’s holding that it has jurisdiction.’ * * * ” (Emphasis sic.) State ex rel. Bradford v. Trumbull Cty. Court (1992),
In his third proposition, Sellers asserts that the defamation action was a compulsory counterclaim under Civ.R. 13(A) that was required to be raised by Foley and Steele in the Franklin County malpracticе action. Assuming, arguendo, that the attorneys’ defamation claim constituted a compulsory counterclaim in .the legal malpractice suit, prohibition would still not lie:
“The trial court’s order does not amount to a complete and total usurpatiоn of judicial authority from which an appeal would be inadequate. The trial court has at least basic jurisdiction to determine whether relator’s counterclaims are compulsory under Civ.R. 13(A) or permissive under Civ.R. 13(A)(1). Merely because the trial court’s determination may be erroneous does not deprive it of jurisdiction over the claims. Based on the foregoing, wе find that the trial court has jurisdiction to make a decision * * * whether relator’s claim is compulsory in nature and falls without the exception enumerated in Civ.R. 13(A)(1). Assuming that there exists error in the trial court’s decision, such an error is properly corrected on appeal and is not an adequate ground for the issuance of a writ of prohibition.” State ex rel. Massarо Corp. v. Franklin Cty. Court of Common Pleas (1989),65 Ohio App.3d 428 , 431,584 N.E.2d 756 , 758-759. Sellers’s third proposition lacks merit.
Judgment affirmed.
