Plaintiffs appeal as of right the trial court’s grant of accelerated judgment, GCR 1963, 116.1(5), to the defendants based upon plaintiffs Guenter and Erna Wallisch’s failure to file their action for the loss of their son Peter’s society and companionship and damages for medical ex *421 penses within the time period set forth in the statute of limitations.
Defendants cross-appeal the trial court’s denial of their motion for accelerated judgment as to Erna Wallisch’s medical malpractice claim as guardian on behalf of Peter Wallisch. Defendant Pediatric Associates, P.C., was dismissed by stipulation below and is, therefore, not a party to this cross-appeal.
Plaintiffs filed this action on June 19, 1981. They alleged that shortly after Peter Wallisch was born on April 6,1958, he developed an eczema-like rash. Defendants Dr. Lugg and Dr. Battley treated Peter for this condition in 1958-1959. In April, 1959, defendant Dr. Fosnaugh began teating Peter as an outpatient at defendant Henry Ford Hospital. Dr. Fosnaugh placed Peter on a high-protein diet as part of that treatment.
On July 9, 1960, Peter was properly diagnosed as having phenylketonuria (PKU), an inability to tolerate protein. PKU causes mental retardation unless properly and promptly diagnosed and treated. Plaintiffs alleged that the defendants were negligent in failing to promptly and properly diagnose and treat Peter’s PKU. Plaintiffs assert that, as a consequence of that negligence, Peter suffers from permanent and severe mental retardation.
In their motions for accelerated judgment, defendants argued that the Wallisches’ claim for damages for loss of Peter’s society and for medical expenses incurred on Peter’s behalf was barred by the medical malpractice statute of limitations applicable in 1959-1960, MCL 609.13(3); MSA 27.605(3). Defendants argued that the statute requires a claim to be brought within two years of the accrual of the cause of action and that because plaintiffs knew of the PKU diagnosis and of Pe *422 ter’s retardation in 1960 plaintiffs’ action accrued at that time as a matter of law.
Plaintiffs responded by way of Erna Wallisch’s affidavit. She stated she and her husband did not discover that the defendant’s diagnoses and treatment of Peter were improper until April of 1981. At that time, plaintiffs became aware of defendants’ wrongdoing when they discussed Peter’s condition with other parents of institutionalized mentally retarded adults. Plaintiffs argued that because they filed their complaint within six months of that discovery date it was timely filed. MCL 600.5805(4); MSA 27A.5805(4), and MCL 600.5838; MSA 27A.5838.
The trial court granted accelerated judgment as to this claim without finding as a matter of law a particular discovery date. Rather, the trial court simply stated that under the law defendants were entitled to accelerated judgment.
Our first task is to determine which statute of limitations applies in this case. The current statute provides that a malpractice claim accrues when treatment is discontinued. A plaintiff has two years from that accrual or six months from the time the plaintiff discovers or should have discovered the malpractice claim, whichever is later, to file an action before it becomes barred. MCL 600.5838; MSA 27A.5838. However, that statute does not apply here. The applicable statute of limitations is that which is in effect at the time a plaintiff’s cause of action arises.
Winfrey v Farhat,
The alleged act of malpractice in this case is one of omission: defendants’ failure to properly diagnose and treat Peter Wallisch from 1958 to 1960. Thus, the date the asserted malpractice accrued was sometime prior to July 9, 1960, when Peter’s condition was properly diagnosed. For Drs. Lugg and Battley, the accrual date was earlier as they ceased treating Peter sometime in 1959.
The applicable statute of limitations at that time was MCL 609.13(3); MSA 27.605(3), which provided a plaintiff two years from the date the cause of action accrued to file a malpractice claim. In
Johnson v Caldwell,
We now address whether the trial court properly granted accelerated judgment to defendants under this two-year limitation period. Certainly the Wallisches’ claim was filed more than two years after the accrual of defendants’ alleged acts of malpractice. However, this record does not show with certainty that the plaintiffs failed to file their claim more than two years after they discovered *424 or reasonably should have discovered the asserted malpractice.
Where a plaintiff has requested a jury trial, accelerated judgment under GCR 1963, 116.1(5) should not be granted if there are factual disputes regarding when discovery occurred or reasonably should have occurred.
Leyson v Krause,
In
Leary, supra,
this Court held that, in order to find that a plaintiff discovered or reasonably should have discovered the asserted malpractice, the plaintiff "must know of the act or omission itself, * * * and have good reason to believe the act itself was improper or was done in an improper manner.”
*425
Although the Wallisches were aware of the defendants’ acts prior to Peter’s PKU diagnosis and aware of his mental retardation, the determination of when they discovered the asserted wrongdoing involves a factual dispute. Plaintiffs alleged that the discovery date was in April, 1981. Defendants argue that the Wallisches should reasonably have discovered the alleged malpractice in 1960 following the PKU diagnosis. This factual dispute is a question for the jury that plaintiffs requested. See,
Ellis v Lauter,
Defendants argue on cross-appeal that the trial court erred by failing to grant them accelerated judgment on Erna Wallisch’s claim brought on Peter Wallisch’s behalf despite Peter’s apparent protection from the statute of limitations due to his mental disability. The disability savings provision applicable to Peter’s cause of action is MCL 609.15; MSA 27.607, which provides that if a person entitled to bring a cause of action is insane at the time the cause of action accrues, that person may file his or her claim before the applicable period of limitation runs after the disability is removed. As determined above, the applicable limitation period in this case is two years. Therefore, Peter Wallisch’s claim is not barred until two years have passed after his insanity disability is removed.
The parties do not dispute that Peter Wallisch is mentally retarded to the extent that he is "insane” under the disability savings provision or that his mental retardation is a permanent condition. Rather, the defendants argue that the ap *426 pointment of Erna Wallisch as Peter’s guardian on May 25, 1978, removed that disability so that the limitation period commenced to run from that date. Therefore, defendants assert, Peter Wallisch’s claim is barred under the disability savings provision because the complaint was filed on June 19, 1981, more than two years after the disability was removed.
