Laura and Nancy Scheunemann appeal from a judgment dismissing their medical malpractice action against Dr. David Rowe, Janesville Medical Center, Fort Atkinson Memorial Hospital Association, and State of Wisconsin Patient Compensation Fund (defendants). The issue is whether the trial court lost competency to exercise its jurisdiction because Scheunemanns did not file a mediation request as required by sec. 655.445, Stats.[1] We conclude the court did not lose competency and we reverse the judgment and remand for further proceedings.
Scheunemanns filed their complaint on June 26, 1987. On November 3, 1987 and April 13, 1988, defendants moved to dismiss the action for Scheunemanns' failure to file a request for mediation as required by sec. 655.445, Stats. Scheunemanns opposed the motion but did not file the request for mediation. The record on appeal fails to show that they have ever filed a request. *304 The trial court dismissed the action with prejudice. It reasoned that Scheunemanns' failure to participate in mediation, as required by statute, deprived the court of "jurisdiction."
We conclude that the trial court's order must be reversed because the court erroneously interpreted sec. 655.445, Stats. According to Eby v. Kozarek, 153 Wis. 2d 75, 77, 450 N.W.2d 249, 250 (1990), "the statutory requirement is mandatory with respect to the requirement to file a request for mediation but directory with respect to the time limitation within which the request is filed." The Eby court continued:
The most probable indication of the consequences attaching to an untimely request for mediation intended by the legislature is found in sec. 655.445(3), Stats., which provides that no discovery may be made and no trial, pretrial conference or scheduling conference may be held until the expiration of the mediation period under sec. 655.465(7). This language supports the court of appeals' conclusion that the failure to timely file for mediation merely postpones the plaintiff's opportunity for relief for the period of time the plaintiff delays filing the mediation request.

Id. at 81, 450 N.W.2d at 252 (emphasis added). The Eby court noted that trial courts can protect defendants from dilatory plaintiffs. Id. at 82, 450 N.W.2d at 252. Eby was released after the trial court entered the order on appeal. Eby is nevertheless applicable to this case.
The same principles should apply to a complete failure, as here, to file a mediation request. Scheunemanns' failure to file merely postpones their opportunity for relief. It is Scheunemanns, not the court, who cannot go forward until they file. Accordingly, the trial court never *305 lost competency to proceed with the action.[2]
We therefore reverse the judgment and remand the case to the trial court. Our mandate does not prevent the court from entertaining a motion to dismiss addressed to its discretionary authority "to exercise control over the judicial business before it." Id.
By the Court.Judgment reversed and cause remanded.
