Nelson asserts that the court of appeals erred in denying the writ because it improperly sua sponte converted Judge’s Russo’s motion to dismiss to a motion for summary judgment without notifying him of the conversion and giving him an opportunity to respond. Under Civ.R. 12(B) and 56(C), a court must notify all parties at least fourteen days before the time fixed for hearing when it converts a motion to dismiss for failure to state a claim into a motion for summary judgment. Petrey v. Simon (1983),
Nevertheless, this error was harmless because the court of appeals could have taken judicial notice of the mootness of Nelson’s writ action without converting Judge Russo’s dismissal motion to a motion for summary judgment. State ex rel. Findlay Publishing Co. v. Schroeder (1996),
The entry and findings of fact and conclusions of law attached to Judge Russo’s dismissal motion established that Judge Russo had performed the requested act. Neither mandamus nor procedendo will compel the performance of a duty that has already been performed. State ex rel. Grove v. Nadel (1998),
Based on the foregoing, we affirm the judgment of the court of appeals.
Judgment affirmed.
