PER CURIAM.
State Farm Mutual Automobile Insurance Company, as subrogee of its insured, Dianne Taylor, appeals as of right the order of Kent Circuit Judge Dennis Leiber allowing Bruce Galen to amend his prior rejection of mediation to reflect that both parties accepted the mediation award of $9,000 in favor of State Farm. Because Galen, through his insurer, Citizens Insurance Company, had rejected the mediation evaluation, State Farm asserts that Galen was improperly allowed to amend his rejection after the prescribed twenty-eight-day period for acceptance had elapsed.
The facts of this case are undisputed. On February 5, 1988, Galen and Taylor were involved in an automobile accident. On August 1, 1989, Taylor *276 brought suit against Galen, alleging that Galen negligently struck her with the automobile he was driving.
On November 27, 1989, State Farm, as subrogee of Taylor, brought suit against Galen. On July 18, 1990, Citizens brought a declaratory judgment action against State Farm, Galen, and Taylor, seeking a declaration that it owed no duty to defend or indemnify Galen because he intentionally caused Taylor's injuries. Following a hearing on Galen's motion for summary disposition in the declaratory judgment action, the trial court granted Galen's motion, holding that Citizens had a duty to defend and indemnify him.
On March 26, 1991, the case was submitted to mediation. On April 29, 1991, the parties were notified that mediation resulted in a $9,000 award for State Farm and against Galen. The notice stated that State Farm accepted the mediation evaluation and that Galen rejected it.[1]
On April 29, 1991, Galen moved for sanctions and declaratory relief against Citizens, alleging that Citizens erroneously rejected the mediation award under the mistaken belief that it had no duty to indemnify him for any judgment entered against him.[2] On June 14, 1991, the trial court heard arguments on Galen's motion. Citizens conceded that it rejected the mediation award on the basis of its mistaken belief that it had no duty to indemnify Galen. Because Citizens had proceeded under a mistaken belief, counsel for Galen orally moved to allow Galen to retroactively accept the $9,000 mediation award that had been rejected by *277 Citizens. The trial court granted Galen's motion for retroactive acceptance of the mediation award, stating that Citizens did not appreciate the import of the court's earlier ruling and that acceptance of an award six weeks after the time for acceptance did not unduly prejudice State Farm's rights.
After denying State Farm's motion for rehearing, the trial court entered an order granting Galen's motion to amend the rejection of mediation, holding that the case was settled as a result of the mutual acceptance by the parties of the $9,000 mediation award. A final amended order was entered on September 26, 1991.
In an issue of first impression, we must decide whether a trial court has discretion, after expiration of the twenty-eight-day period for acceptance or rejection of an award provided in MCR 2.403(L) (1), to set aside a party's rejection of a mediation award and declare the award to be accepted by both parties over the objection of the opposing party who wished to withdraw its acceptance.
MCR 2.612(C)(1) permits a trial court to relieve a party or the legal representative of a party from a final judgment, order, or proceeding on the grounds of mistake, inadvertence, surprise, or excusable neglect. This Court has previously determined that a trial court has discretion to set aside a party's acceptance of a mediation evaluation if failure to do so would result in substantial injustice. Reno v Gale, 165 Mich App 86, 92-93; 418 NW2d 434 (1987). In Reno, this Court stated:
It is within the trial court's discretion to set aside a party's acceptance of a mediation evaluation prior to the entry of a judgment upon the award. Hauser v Roma's of Michigan, Inc, 156 Mich App 102, 104; 401 NW2d 630 (1986); MGM Brakes Division of Indian Head, Inc v Uni-Bond, *278 Inc, 417 Mich 905; 330 NW2d 853 (1983); Busch v Hoffmeyer, 158 Mich App 786, 790-791; 405 NW2d 220 (1987). Although discretionary, a court should set aside a judgment on the acceptance only if failure to do so would result in substantial injustice. Hauser, supra at 104. In making a determination, the court must "strike a balance between the goal of remedying injustice, on the one hand, and the desire to achieve finality in litigation, on the other hand." Id. at 104-105. [Reno, supra at 92-93.]
In Reno, the plaintiff accepted a mediation evaluation of $12,500. The defendants also accepted the evaluation under MCR 2.403(L)(1) by virtue of their failure to respond within twenty-eight days.[3] The defendants sought to have the acceptance set aside, claiming that a timely rejection had been sent but never received by the court. This Court reversed the trial court's decision and granted the defendant's request for relief on the basis that a lost letter would presumably constitute a mistake or excusable neglect. Id. at 93-95.
In this case, the mediation evaluation was rejected by virtue of Citizens' failure to respond within twenty-eight days. Both counsel for Galen and Citizens confirmed at the hearing on the motion that Citizens did not respond to the mediation evaluation on behalf of Galen because of its mistaken belief that it did not have a duty to defend or indemnify Galen. Under these circumstances, we conclude that the trial court had discretion to allow Galen to amend his earlier rejection to reflect acceptance of the award. Although the court has the discretion to order entry of a judgment on the award, it should do so only if the opposing party reaffirms its continued acceptance *279 of the award. Because State Farm indicated that it no longer wished to accept the award and wanted to proceed to trial, the trial court abused its discretion in authorizing entry of the judgment against Galen.
Reversed.
NOTES
[1]  The mediation evaluation effectively was rejected after Citizens failed to file a written acceptance or rejection within twenty-eight days. MCR 2.403(L)(1).
[2]  Galen asserted that he had instructed Citizens to accept the mediation evaluation.
[3]  Under the current version of MCR 2.403(L)(1), failure to respond to a mediation evaluation within twenty-eight days constitutes a rejection.
