dissenting. The real issue presented to this court in this appeal is whether the decision of this court in Oliver v. Kaiser Community Health Found. (1983), 5 Ohio St. 3d 111, may be applied retroactively to revive a cause of action which was extinguished nearly eleven years before the Oliver decision was rendered. This court, in Oliver, held that a cause of action in medical malpractice accrues, and the statute of limitations begins to run, upon discovery of the injury.
On June 22, 1971, the date the alleged act of malpractice against appellant occurred, the statute of limitations for actions in medical malpractice was that portion of R.C. 2305.11 which is contained in division (A) of the current statute. The 1971 version of R.C. 2305.11 stated, in pertinent part: “An action for * * * malpractice * * * shall be brought within one year after the cause thereof accrued * * The four-year absolute bar contained in R.C. 2305.11(B) was not enacted until 1975. See Am. Sub. *12H.B. No. 682, effective July 28, 1975. (136 Ohio Laws, Part II, 2809, 2810-2811.)
At the time the alleged act of malpractice against appellant occurred, this court interpreted the time of “accrual” under R.C. 2305.11 to be, at the latest, the time of termination of the physician-patient relationship, and not the date the injury was discovered. DeLong v. Campbell (1952), 157 Ohio St. 22 [47 O.O. 27]; Wyler v. Tripi (1971), 25 Ohio St. 2d 164 [54 O.O.2d 283].
Other than the statutorily imposed tolling of the statute of limitations for minority and other disabilities contained in R.C. 2305.16, prior to 1983 the only exception to the one-year statute of limitations was the discovery rule in foreign object cases, which was adopted by this court in 1972. Melnyk v. Cleveland Clinic (1972), 32 Ohio St. 2d 198 [61 O.O.2d 430]. In Melnyk, this court permitted the statute of limitations to be tolled in cases which involved a foreign object negligently left in the plaintiffs body, until the object was discovered. Until the case of Oliver v. Kaiser Community Health Found., supra, this court had specifically refused to extend the discovery rule to medical malpractice cases which did not involve a foreign object. Wyler v. Tripi, supra.
Thus, at the time the alleged act of negligence in this case occurred in 1971, under the statute of limitations in effect at that time, appellant had one year after the termination of the physician-patient relationship to bring her cause of action. The relationship between appellant and appellee terminated shortly after the surgery in 1971. Since appellant failed to bring an action within the time permitted by the statute, her cause of action was extinguished in 1972.
The rendering by this court in 1983 of the Oliver decision cannot be deemed to have revived appellant’s formerly expired cause of action. The law of Ohio has long been that a cause of action once extinguished is not revived by changes in the applicable statute of limitations which occur subsequent to the expiration of the cause of action. Cox v. Dept. of Transportation (1981), 67 Ohio St. 2d 501, 505-506 [21 O.O.3d 313].
In this case, appellant’s cause of action expired in 1972 under the one-year statute of limitations and relevant case law then in effect. Having so expired, the cause of action cannot be revived .some eleven years later by the Oliver decision. The majority cites Peerless Electric Co. v. Bowers (1955), 164 Ohio St. 209 [57 O.O. 411], in support of its decision to discard application of the termination rule in this case. However, the Peerless case involved the retroactive application of a decision of this court regarding the propriety of including federal securities in the tax base of a corporation for purposes of computing the franchise tax. In that case, the retroactive application of the court’s decision in question did not operate to revive a previously extinguished right. The Peerless case clearly did not involve the retroactive application of a statute of limitations; nor does it stand for the proposition that subsequent case law may revive an expired statute of limitations.
*13Further, appellant argues that the Oliver decision specifically held that the discovery rule applies retroactively to include alleged acts of malpractice accruing prior to July 28, 1975. However, nowhere in the Oliver decision is either the retroactive application of the decision or the date July 28, 1975 discussed. Moreover, the alleged act of negligence in Oliver occurred on or after September 16, 1975, almost two months after the date cited by appellant. While the retroactive application of case law may arguably operate to preserve an existing right to sue for a longer period by extending a statute of limitations period which is running but not yet expired, it may not operate to revive a right which no longer exists. Accordingly, appellant’s claim is barred.
However, even if one adopts the majority’s position that the discovery rule set forth in Oliver does apply to this case and operates to revive appellant’s extinguished cause of action, the decision of the trial court sustaining appellee’s motion for sumary judgment was still proper. A review of several previous decisions of this court, including those cited by appellant, makes it clear that, contrary to appellant’s argument, the discovery rule is controlled by the absolute limitation of four years contained in R.C. 2305.11(B).
R.C. 2305.11(B) states, in pertinent part:
“In no event shall any medical claim against a physician, podiatrist, or a hospital or a dental claim against a dentist be brought more than four years after the act or omission constituting the alleged malpractice occurred. The limitations in this section for filing such a malpractice action against a physician, podiatrist, hospital, or dentist apply to all persons regardless of legal disability and notwithstanding section 2305.16 of the Revised Code * * (Emphasis added.)
The plain language of this statute makes it clear that it applies to all causes of action and begins to run from the date the alleged act occurred, regardless of the date the cause of action actually accrues.
Even if the appellant had an accrued substantive right at the time R.C. 2305.11(B) was enacted, Section 28, Article II of the Ohio Constitution does not prohibit such retroactive application, provided a reasonable time is permitted after the amendment for suit to be brought. See Cook v. Matvejs (1978), 56 Ohio St. 2d 234 [10 O.O.3d 384]; and Baird v. Loeffler (1982), 69 Ohio St. 2d 533 [23 O.O.3d 458]. This court has held that:
“* * * [T]here is a distinction ‘between the operation of an amended statute of limitations which totally obliterates an existing substantive right and one which merely shortens the period of time in which the remedy can be realized.’ [Emphasis sic.] The latter application of an amended statute is not unlawful as long as a prospective claimant is still afforded a reasonable time in which to enforce his right.” Baird, at 535, quoting Cook, at 237.
This court has repeatedly applied amended statutes of limitations to causes of action which accrued prior to the date of the amendment, and measured the time for bringing suit as if the cause of action arose on the *14date the statute was amended. Baird, supra; Cook, supra. Applying this rule to the case at bar, appellant had no more than four years from the date of the amendment of the statute of limitations to bring her action. Thus, even under the interpretation applied in the Cook case, the statute of limitations expired, at the latest, on July 28, 1979.
Appellant argues that Adams v. Sherk (1983), 4 Ohio St. 3d 37, compels this court to reverse the court of appeals and find that R.C. 2305.11(B) may not be applied retroactively to the cause of action in this case. However, Adams v. Sherk is distinguishable from the case at bar. Unlike the instant case, Adams was a foreign-object case brought under the rule of Melnyk, supra. In Melnyk, the court held that although the cause of action accrued when the physician-patient relationship terminated, the running of the statute of limitations was tolled until the foreign object was discovered. This court at 201 stated:
“Thus, while a cause of action for medical malpractice accrues, at the latest, when the physician-patient relationship finally terminates, the negligent leaving of a metallic forceps and a nonabsorbent sponge inside a patient’s body during surgery will toll the running of the statute of limitation upon that cause of action until such time as the patient discovers, or by the exercise of reasonable diligence should have discovered, the negligent act.”
Thus, in Adams, the plaintiff had an accrued substantive right when the statute was amended in 1975 because the cause of action — malpractice resulting from negligently leaving a foreign object in the plaintiff’s body — accrued on termination of the physician-patient relationship, but the running of the statute of limitations was tolled under the lav/ in effect at that time.
Unlike the Melnyk rule, the rule in Oliver is that a cause of action does not accrue until the resulting injury is discovered. This court, in Oliver, held:
“Under R.C. 2305.11(A), a cause of action for medical malpractice accrues and the statute of limitations commences to run when the patient discovers, or, in the exercise of reasonable care and diligence should have discovered, the resulting injury. * * *”
Thus, applying Oliver to this case, appellant had no accrued substantive right in 1975 to be destroyed by the amendment of the statute of limitations. However, the “act or omission constituting the alleged malpractice” was years before her cause of action under Oliver accrued, i.e., appellant discovered her injury in June 1983. Therefore, the four-year bar had long since ended her ability to bring the within action.
Accordingly, I would affirm the judgment of the court of appeals.
Locher, J., concurs in the foregoing dissenting opinion.
