¶1Plaintiff-appellants appeal the order of the trial court dismissing the instant action as a sanction for failure to provide discovery. We reverse.
¶2The instant case arose out of two automobile accidents involving plaintiff-appellant, Jerry J. Ladrach. The original action was dismissed without prejudice following appellant's failure to provide discovery, his deposition having been terminated when he was unable to endure deposition questioning and struck counsel for the appellee.
¶3Upon refiling of the case, discovery again commenced with the appellees serving notice to depose Jerry. Appellant's counsel then filed a motion for a protective order on the ground that Jerry was mentally incompetent to testify. Appellant's counsel also filed a motion to substitute plaintiff-appellant, Mary J. Ladrach, as party in her capacity as guardian for Jerry.
¶4Appellees then filed a motion for Jerry to submit to a psychological evaluation. The trial court granted the motion for the psychological evaluation and denied appellant's motions. Nevertheless, Jerry did not appear for the scheduled psychological evaluation. The trial court denied the motion to dismiss, but imposed sanctions pursuant to Civ. R. 37. The order that appellant's claims would be limited to Jerry's claimed physical injuries arising out of the automobile accidents. The above sanction was to be deferred if Jerry submitted to the psychological evaluation within forty-five days. The appellants were also assessed the costs of the previously scheduled evaluation.
¶5Jerry did later submit to a psychological evaluation, and the findings of the psychologist were submitted to the trial court. The appellees once again gave notice to appellants to appear for scheduled depositions. Appellants filed a further motion for a protective order. The trial court denied appellant's motion.
¶6Jerry did appear at a scheduled deposition as ordered by the trial court. However, the deposition was once again terminated when Jerry became enraged and threw hot coffee at appellee's counsel.
¶7The appellees subsequently moved to dismiss the case for appellant's failure to comply with the discovery orders of the trial court. The trial court granted the motion with prejudice, and Jerry and Mary Ladrach now appeal.
¶8ASSIGNMENT OF ERROR I
¶9"The trial court erred as a matter of law by failing to substitute Guardian as a party for plaintiff, Jerry J. Ladrach, before ruling on Motions for protective order, psychological examinations, dismissal and sanctions."
¶10Appellants assert that the trial court erred in failing to substitute Mary J. Ladrach, guardian for Jerry Ladrach, as the proper party in the instant action.
¶11Civ. R. 25(B) provides:
¶12"If a party is adjudged incompetent, the court upon motion served as provided in subdivision (A) of this rule shall allow the action to be continued by or against his representative."
¶13The record reveals that the Probate Division of the Wayne County Court of Common Pleas adjudicated Jerry incompetent on September 1, 1987. On March 7, 1988, appellants filed a motion to substitute Mary, Jerry's guardian, as the proper party in the instant action. The trial court, however, did not allow the substitution prior to the trial court's dismissal of the action.
¶14Civ. R. 25 requires substitution of parties upon a finding of incompetency. However, an appellate court will not reverse a judgment on the basis of any error that is harmless. Civ. R. 61. Harmless error is one which does not affect the substantial rights of the parties. Id.; Leichtamer v. American Motors Corp. (1981), 67 Ohio St. 2d 456, 457.
¶15In the case subjudice, Mary was a party to the action and represented by the same counsel as Jerry. Mary received notice of all motions and discovery orders. Moreover, following the motion for substitution, the trial court directed several discovery orders to Mary in her capacity as Jerry's guardian.
¶16Although the trial court erred in failing to substitute Mary as the proper party in the instant action, we hold that such failure was not prejudicial to the appellants, and therefore, the error is harmless. The first assignment of error is overruled.
¶17ASSIGNMENT OF ERROR II
¶18"The trial court abused its discretion to the prejudice of the plaintiff-appellants Ladrach by *498dismissing this case (Judgment Entry, September 25, 1989) because Jerry J. Ladrach was mentally unable to withstand the taking of his deposition."
¶19Appellants assert that the trial court abused its discretion in dismissing appellant's action.
¶20Civ. R. 37(B)(2) provides various sanctions for failure to comply with discovery, with dismissal of the action being the most harsh. Russo v. Goodyear Tire & Rubber Co. (1987), 36 Ohio App. 3d 175, 178. It is exclusively within the trial court's discretion to determine the particular sanction to be imposed for the particular infraction committed. Id.The reviewing court cannot substitute its judgment for that of the trial court. Id. at 179. The reviewing court, however, may reverse the trial court's decision if the degree of the sanction is disproportionate to the seriousness of the discovery infraction, and such decision by the trial court was arbitrary and an abuse of discretion. Id.An abuse of discretion is more than an error of law or judgment, but implies that the attitude on the part of the trial court is unreasonable, arbitrary or unconscionable. Ruwe v.Bd. of Springfield Twp. Trustees (1987), 29 Ohio St. 3d 59, 61.
¶21In the case sub judice, we hold that the trial court abused its discretion in dismissing appellant's action with prejudice. The record reveals that Jerry's failure to comply with the discovery orders was not due to any willfulness or bad faith. Russo, supra;See Rauchenstein v. Kroger Co. (1981), 3 Ohio App. 3d 178, 180. There was evidence on the record that the failure to comply with the discovery orders was due to reasons beyond Jerry's control, such reason being mental illness. Id.Perhaps the proper sanction should have been to prohibit Jerry from testifying at trial. Nevertheless, dismissal of the action with prejudice under the instant facts is much too harsh a sanction, and such sanction was arbitrary and an abuse of discretion. The second assignment of error is well taken.
¶22ASSIGNMENT OF ERROR III
¶23"The trial court abused its discretion by dismissing the cause of action of plaintiff-appellant Mary J. Ladrach because of the conduct of her mentally incompetent ward."
¶24Mary's action for loss of consortium is derivative of Jerry's action. Messmore v. Monarch Machine Tool Co. (1983), 11 Ohio App. 3d 67, 68-69. Mary's action can be maintained as long as Jerry's action continues. Id. at 69. The third assignment of error is well taken.
¶25The judgment of the trial court is reversed and the cause is remanded for further proceedings.
¶26Judgment reversed and cause remanded.
