*1024 MEMORANDUM DECISION AND ORDER
This diversity malpractice action was filed on October 8, 1982, alleging negligence by the defendant-physician in treating plaintiff “on or about October 11,1980.” Defendants have moved to dismiss the complaint on the basis of plaintiffs failure to timely serve a 90-day pre-filing notice on defendants as required by 24 M.R.S.A. § 2903. Since the parties have presented materials outside of the pleadings which have not been excluded by the court, the motion to dismiss is treated as a motion for summary judgment under Rule 56. Fed.R.Civ.P. 12(b).
Plaintiff alleges that he was treated by defendant Robert S. Furman, M.D., of Fur-man, Wickenden and Wickenden, P.A., at the Penobscot Bay Medical Center in Rock-land, Maine “on or about October 11, 1980,” for a dislocated thumb. On October 8,1982 plaintiff brought the present action. On October 13, 1982 Dr. Furman and the professional association were served with copies of the complaint. On November 3, 1982, defendants moved to dismiss the complaint. On December 6, 1982, defendants received additional copies of the complaint to which had been added plaintiffs signature subscribed and sworn before a notary public. Defendants have received no other notice of the claim which is the subject of this action.
Title 24 M.R.S.A., section 2903 (Supp. 1984), enacted in 1977, provides:
No action for death or injuries to the person arising from any medical, surgical or dental treatment, omission or operation shall be commenced until at least 90 days after written notice of claim setting forth under oath the nature and circumstances of the injuries and damages alleged is served personally or by registered or certified mail upon the person or persons accused of wrongdoing. Any applicable statute of limitations shall be tolled for a period of 90 days from service of notice.
In
Givertz v. Maine Medical Center,
Plaintiff responds to defendants’ argument that Givertz mandates dismissal of the present action by asserting (1) that Givertz is distinguishable; (2) that Givertz, decided on April 26, 1983 following the commencement of suit and service of the pre-filing notice in this case, should not be applied retroactively; (3) that the notice requirement of section 2903 does not apply in this federal diversity action; (4) that the section 2903 notice provision violates the Equal Protection and Due Process clauses of the United States Constitution and the Maine Constitution; (5) that section 2903 is contrary to Me. Const, art. I, § 19; and (6) that 14 M.R.S.A. § 753 denies equal protection insofar as it provides a two-year limitations рeriod for medical malpractice actions.
I. GIVERTZ v. MAINE MEDICAL CENTER
Compliance with Pre-Litigation Notice Requirement
Plaintiff’s argument that, unlike the present case, no notice of claim was ever served in Givertz, misconceives the holding in Givertz. In upholding the trial court’s dismissal of the claim against the defendant physician in Givertz, the Maine court explained:
We immediately point out that in requiring service of a ninety-day mandatory notice of claim prior to the actual bringing of a malpractice suit, the Legislature at the same time integrated this specific legislation into any applicable statute of limitations respecting such actions. Having in mind that such actions must be commenced within two years after the cause of action accrues, whether it be 14 *1025 M.R.S.A. § 753 or 24 M.R.S.A. § 2902, the Legislature affirmatively kept the full two-year period intact by providing a tolling of the limitations statute for the required ninety-day run of the notice of claim. Such integration of the two statutes manifests an intent on the part of the lawmakers to mаke the ninety-day preaction notice of malpractice claims a mandatory requirement within the two-year limitations statute applicable to the commencement of malpractice suits, which statute has been construed by this Court as mandatory. Millett v. Dumais,365 A.2d 1038 (Me. 1976). See also Beegan v. Schmidt,436 A.2d 893 (Me.1981).
As in Givertz, plaintiff filed the present malpractice action within the two-year limitations period but failed to provide the prelitigation notice of claim within that period. 1 Thus, Givertz is essentially indistinguishable.
Relying on
Michaud v. Northern Maine Medical Center,
Retroactivity of Givertz
Plaintiff next contends that
Givertz,
which was decided April 26, 1983, represents a substantial departure from prior holdings and that it should not be applied retroactively. The “contrary” holdings referred to by plaintiff are those in
Michaud v. Northern Maine Medical Center, supra,
and
Dougherty v. Oliviero,
As has been demonstrated, Givertz in no way contradicts Michaud. Nor is Givertz at all inconsistent with Dougherty, which held that where an action is commenced before the expiration of the statute of limitations and a sufficient notice of claim is served within that limitations period, though after the commencement of the action, non-compliance with section 2903 does not necessarily require dismissal, and a stay of proceedings may be appropriate.
The issue in
Givertz:
whether the failure to serve a notice of claim within the two-year limitations period mandated dismissal, was one of first impression for the Maine court. Indeed, the
Givertz
court carefully distinguished its prior holdings in
Michaud
and
Dougherty.
Moreover,
Givertz
did not involve a question of Maine common law, but an interpretation of a 1977 statute, as manifested by the court’s finding of “a clear legislative intent that some notice of claim, be it sufficient or deficient, be served, as mandated by section 2903, within the period of limitations set by the statute as extended by reason of the ninety-day tolling provision of said section.”
Givertz, supra,
Although the Maine court has on occasion declined to give retrospective effect to a new rule of law, see Myrick v. James, 444 *1026 A.2d 987, 1001-02 & n. 14 (Me.1982) (and cases cited), unlike Myrick and the cases cited therein, Givertz did not overrule prior decisional law, nor did it expressly preclude the retrospective application of its holding. Thus, plaintiffs claim that Givertz does not apply retroactively must fail.
Applicability of Pre-Litigation Notice Requirement in Diversity Action
Plaintiff contends that section 2903’s pre-litigation notice requirement should not be applied in this diversity action because the requirement is “procedural” rather than “substantive.” Plaintiff concedes that other state medical malpractice statutes requiring that malpractice claims be initially referred to an arbitration or review board are binding on federal courts sitting in diversity actions.
See, e.g., Feinstein v. Massachusetts General Hospital,
Erie
overruled
Swift v. Tyson,
[T]he question is not whether a statute of limitations is deemed a matter of ‘procedure’ in some sense. The question is whether such a statute concerns merely the manner and the means by which a right to recover, as recognized by the State, is enforced, or whether such statutory limitation is a matter of substance in the aspect that alone is relevant to our problem, namely, does it significantly affect the result of a litigation for a federal court to disregard a law of a State that would be controlling in any action upon the same claim by the same parties in a State court? ... In essence, the intent of [the Erie ] decision was to insure that, in all cases where a federal court is exercising jurisdiction solely because of the diversity of citizenship of the parties, the outcome оf the litigation in the federal court should be substantially the same, so far as legal rules determine the outcome of a litigation, as it would be if tried in a State court.
Id.
at 109,
In a case somewhat analogous to the present one, the Supreme Court, in
Ragan v. Merchants Transfer & Warehouse Co.,
Since that cause of action is created by local law, the measure of it is to be found only in local law. It carries the same burden and is subject to the same defenses in the federal court as in the state court____ It accrues and comes to an end when local law so declares---Where local law qualifies or abridges it, the federal court must follow suit. Otherwise there is a different measure of the cause of action in one court than in *1027 the other, and the principle of Erie R. Co. v. Tompkins is transgressed.
Id.
at 533,
Plaintiff apparently contends that
Hanna v. Plumer,
In
Walker v. Armco Steel Corp.,
The section 2903 requirement that a notice of claim be served upon a malpractice defendant within the applicable Maine period of limitations, as a prerequisite to the right to recover in a court action, renders the notiee-of-claim requirement, like the service-of-summons requirements in
Ragan
and
Walker,
an integral part of the Maine statute of limitations for malpractice actions. No federal rule directly conflicts with the Maine notice-of-claim requirement. Moreover, to refuse to apply section 2903 in this diversity case would produce an inequitable administration of Maine law as between resident and nonresident plaintiffs in malpractice actions, thus contravening the principles of
Erie, supra,
In short, the pre-litigation notice requirement, as an integral part of the statute of limitations, is “intimately bound up” with the rights and obligations of the parties to Maine medical malpractice claims, and, therefore, must be applied in this diversity action.
See Feinstein v. Massachusetts General Hospital,
II. CONSTITUTIONAL CHALLENGES
Plaintiff argues that the pre-litigation notice requirement of section 2903 violates the Equal Protection and Due Process Clauses of the United States Constitution, U.S. Const, amend. XIV, and the Maine Constitution, Me. Const, art. I, § 6-A, as *1028 well as article I, section 19 2 of the Maine Constitution. Plaintiff also contends that the two-year statute of limitations for medical malpractice actions, 14 M.R.S.A. § 753, violates the constitutional requirement of equal protection.
Pre-Litigation Notice
A. Equal Protection
Plaintiff argues that the notiee-of-claim requirement denies equal protection of the laws because it impermissibly distinguishes between medical malpractice plaintiffs and plaintiffs in other tort actions. Plaintiff concedes that the requirement that a notice of claim be served prior to commencing a malpractice action, and within two years of the accrual of the cause of action, does not implicate a fundamental right or a suspect classification and therefore does not invoke the “strict scrutiny” standard of review. However, plaintiff maintains that this court must apply an “intermediate” level of scrutiny, rather than the “rational relationship” test applied in most equal protection challenges.
Generally, social or economiс legislation which does not impinge on fundamental rights or employ suspect classifications does not deny equal protection if the discriminatory classification occasioned by the statute is rationally related to a legitimate governmental objective.
City of Cleburne v. Cleburne Living Center,
— U.S. —, ---,
In certain narrowly defined circumstances, the Supreme Court has applied an intermediate level of scrutiny — requiring the state to demonstrate a “substantial interest” in its discriminatory classification.
See Pickett v. Brown,
The vast majority of federal and state courts which have considered equal protection challenges to statutory schemes aimed at reducing the costs of malpractice litigation by providing for pre-litigation notice and review of claims has applied the rational relationship test.
Seoane v. Ortho Pharmaceuticals, Inc.,
Plaintiff cites, as contrary authority,
Carson v. Maurer,
Additionally, it is not at all clear that the
Carson
test differs significantly from the rational relationship test. The
Carson
language appears to have been taken from
Reed v. Reed,
But assuming that the level of scrutiny applied in Carson is somewhat more stringent than the rational relationship test ordinarily applied in cases involving economic and social legislation, the court declines to follow Carson, in view of the overwhelming authority to the contrary and Maine’s explicit refusal to extend equal protection and due process rights beyond the federal constitutional norm. 4
*1030
In determining whether the challenged statutory discrimination is constitutional, the following questions must be addressed under the rational relationship test: “(1) Does the challenged legislation have a legitimate purpose? and (2) Was it reasonable for the lawmakers to believe that use of the challenged classification would promote that purpose?”
Western & Southern Life Insurance Co. v. State Board of Equalization,
Considering the first step of the analysis, whether the pre-litigation notice provision is directed at a legitimate purpose, the Maine Law Court has explained that the Maine Health Security Act of 1977, 24 M.R.S.A. § 2501,
et seq.,
was enacted “to promote the settlement of disputes and ameliorate the current proliferation of litigation [in medical malpractice]---- For one thing, liability insurance coverage of exposure ... in the area of malprаctice actions was becoming increasingly difficult to obtain, and, if obtainable, was unduly costly.”
Givertz v. Maine Medical Center, supra,
The Pomeroy Commission on Medical and Hospital Malpractice Insurance [Commission] reported a “substantial problem” in Maine involving increasing insurance rates for medical practitioners, with a probable effect on the availability of health care. As summarized in the “Statement of Fact” accompanying the bill, L.D. 727, 108th Me. Legis., 1st Reg.Sess. 21 (1977), which produced the Maine Health Security Act:
The commission to revise the laws relating to medical and hospital malpractice insurance has found that there is a substantial problem in the State concerning the availability and cost of malpractice insurance for physicians and hospitals. The commission has found further that the situation has affected the availability of health care in some areas and the cоst of health care in all areas of the State. Further deterioration is inevitable unless action is taken now.
Plaintiff challenges the legislative findings by pointing to portions of the Commission report indicating that the Commission considered Maine doctors and hospitals to be in a comparatively “favorable” position when viewed in light of the medical practice problem at the national level. However, while recognizing that the situation in Maine is not “cataclysmic,” the Commission found that there was a “substantial problem” affecting Maine health care.
Plaintiff relies on
Boucher v. Sayeed,
However, Boucher’s premise, that only a “crisis” can give rise to a legitimate state interest in attempting legislative solutions to malpractice insurance coverage problems, is open to question. Moreover, unlike Boucher, plaintiff here has not presented facts to indicate that the problem perceived by the Maine legislature in 1977 was illusory. Indeed, Maine was certainly not alone among the states in perceiving a need for legislative action to avеrt the problems of health care cost and availability resulting from rising malpractice insurance rates. See generally Note, Medical Malpractice Statute of Repose: An Unconstitutional Denial of Access to the Courts, 63 Neb.L.Rev. 150, 160-62 (1983).
Next, it is necessary to consider whether it was reasonable for the Maine Legislature to believe that the differentiation between medical malpractice plaintiffs and other personal injury plaintiffs, i.e., the requirement that the former group alone provide a pre-litigation notice, would promote the stated purpose of maintaining the availability of quality health care at an affordable cost throughout the state.
In its report to the legislature the Commission stated:
Notice of claim. The Commission believes that any reasonable measure that helps weed out doubtful claims and encourages the settlement of meritorious ones is beneficial to the parties and public. In malpractice claims this may be the result if there is a mandatory waiting period prior to suit in which negotiations may take place.
Commission Report xxiii. The bill submitted to and enacted by the legislature included a mandatory 90-day pre-litigation notice “[i]n order to encourage settlement of disputes,” L.D. 727 (Statement of Facts) 108th Me.Legis., 1st Reg.Sess. 21 (1977).
The Maine Law Court stated in
Dougherty v. Oliviero,
In
Givertz v. Maine Medical Center,
The Legislature, in 24 M.R.S.A. § 2903, intended to implement the recommendation of the Pomeroy Commission which viewed the mandatory ninety-day notice of medical malpractice claims prior to the commencement of any action for damages on account thereof as a reprieve period before the parties locked horns in a very sensitive judicial proceeding, the Commission believing that such waiting period prior to suit would be beneficial to the parties and the public by helping weed out doubtful claims and encouraging the settlement of meritorious ones.
Id.
at 550.
See also Taylor v. Hill,
Plaintiff contends that the pre-litigation notice requirement does not in fact help weed out doubtful claims or encourage the settlement of meritorious ones and thus cannot be said to be reasonably related to its purported objective. Plaintiff points to (1) other disincentives discouraging the litigation of unfounded claims, including exposure to liability for malicious prosecution and contingent fee arrangements; (2) the option of the malpractice claimant to settle his or her claim prior to suit; (3) the availability of pretrial procedures for settling claims or disposing of meritless claims; and (4) “substantial evidence suggesting” that, as a tactical device, insurers wait until immediately prior to trial to settle claims.
In evaluating these contentions the court is mindful that the requirement of equal protection is satisfied if the Maine Legislature “could rationally have decided” that the notice provision either itself or in combination with other provisions “might” help to accomplish a legitimate objective,
Minnesota v. Cloverleaf Creamery Co.,
The presence of other disincentives to pursuing unfounded claims does not nеgate the potential benefits of the
additional
disincentive that may obtain from affording an opportunity for a pre-litigation response to the malpractice claim, i.e. the potential for (1) exposing and resolving unfounded claims prior to the commencement of costly litigation and (2) arriving at prelitigation settlements of nonfrivolous claims not yet inflated by litigation costs. Similarly, the availability of court procedures for disposing of or settling claims does not avoid the “expense, time limits, and other pressures associated with [litigation],”
Dougherty, supra,
Although, as plaintiff suggests, a malpractice claimant has always been able to pursue settlement prior to commencing suit, the prelitigation notice requirement *1033 insures that malpractice defendants have such an opportunity as well, thus contributing to the prospect for nonjudicial resolution of claims.
Finally, plaintiffs assertions (1) that “insurers” consciously employ the litigation tactic of refusing settlement until immediately prior to or during trial, and (2) that the notice requirement will increase the cost of malpractice litigation, are not supported by any evidence in the record nor do they negate the benefit which will accrue if a substantial number of physicians and insurers are able to settle or otherwise resolve claims without incurring the expense of litigation.
Plaintiff correctly points out that, in
Carson v. Maurer,
To be sure, those states which have responded to the medical malpractice problem by
mandating
arbitration or panel review of claims may have taken a more effective approach toward weeding out frivolous claims and encouraging the settlement of meritorious ones. Accordingly, courts confronted with such statutes have had little trouble concluding that such mandatory review can reasonably be expected to promote the goal of reducing malpractice insurance costs.
See Seoane v. Ortho Pharmaceuticals, Inc.,
B. Due Process
Plaintiff does not explain, through argumént or reference to authority, how section 2903 violates “due process.” Assuming that it is plaintiff's contention that the statutory imposition of a pre-litigation notice requirement denies substantive due process, it is well-established that legislative acts adjusting economic burdens and benefits carry a presumption of constitutionality and that the person challenging the enactment must establish that the leg
*1034
islature has acted in an “arbitrary and irrational” manner.
Usery v. Turner Elkhorn Mining Co.,
The court has already concluded, in the context of plaintiffs equal protection challenge to section 2903, that legislative enactment of the pre-litigation notice requirement and waiting period is rationally related to the legitimate objective of assuring the continued availability of affordable health care in the face of increasing insurance costs attributable, in part, to litigation costs.
In view of the minimal burden imposed by service of the pre-litigation notice and the ensuing 90-day delay in filing suit, the legislature cannot be said to have acted arbitrarily or irrationally in concluding that the pre-litigation notice requirement was a reasonable approach to reducing litigation costs.
See Seoane v. Ortho Pharmaceuticals, Inc.,
C. Me. Const, art. I, § 19
Finally, plaintiff argues that section 2903 violates article I, section 19 of the Maine Constitution, which provides: “Every person for an injury done him in his person, reputation, property or immunities, shall have remedy by due course of law; and right and justice shall be administered freely and without sale, completely and without denial, promptly and without delay.” Plaintiff essentially contends that the 90-day delay inherent in the pre-litigation notice requirement does not allow for the administration of justice “promptly and without delay,” relying on
State ex rel Cardinal Glennon Hospital v. Gaertner,
Limitations Period for Malpractice Claims
In addition to his equal protection challenge to 24 M.R.S.A. § 2903, plaintiff belatedly 6 brings a similar challenge to the two-year limitations period applicable to medical malpractice actions under 14 M.R. S.A. § 753, contending that it impermissibly distinguishes between victims of medical malpractice and victims of other types of negligence.
In 1931 the Maine Legislature included actions for “malpractice of physicians and all others engaged in the healing art” with certain other tort actions governed by the two-year limitations period, see 14 M.R.S.A. § 753, rather than the residual six-year limitations period, see 14 M.R.S.A. § 752. P.L.1931 Ch. 62.
Once again the court looks “only to whether there is a rational relationship be
*1035
tween the classification and some legitimate governmental purpose in determining whether the statute violates the equal protection clause,”
Brubaker v. Cavanaugh,
Statutes of limitations serve the policy of discouraging stale and fraudulent claims where the loss of evidence makes the proof more difficult or costly.
See Clark v. Gulesian,
There being a rational basis upon which to distinguish between medical malpractice cases and other negligence cases, 14 M.R. S.A. § 753 does not deny equal protection.
See Brubaker v. Cavanough,
III. CONCLUSION
Failure to serve the pre-litigation notice of claim required by 24 M.R.S.A. § 2903 within the two-year limitations period of 14 M.R.S.A. § 753 mandates dismissal of plaintiff's action.
Givertz v. Maine Medical Center,
The section 2903 notice requirement is applicable in this diversity action and Givertz controls even though the two-year limitations period expired prior to the date of that decision. Section 2903 does not deny equal protection or due process, nor does it violate Me. Const, art. I, § 19; and the two-year limitations period for medical malpractice actions does not violate the equal protection clauses of the federal and state constitutions.
Accordingly, defendants’ motion to dismiss, treated as a motion for summary judgment, is hereby GRANTED, and the Clerk is directed to enter judgment for the defendants dismissing all claims.
SO ORDERED.
Notes
. Under Maine law, except in foreign-object surgical malpractice cases, the two-year period of limitations in medical malpractice actions begins running at the time of the negligent act.
See Box v. Walker,
. Every person, for an injury done him in his person, reputation, property or immunities, shall have remedy by due course of law; and right and justice shall be administered freely and without sale, completely and without denial, promptly and without delay.
. Although
Reed,
involving a differentiation on the basis of gender,
see also Mississippi University for Women v. Hogan,
The "substantial relation" language of Reed has also been viewed as requiring a “close fit” between the legislative means and ends, thus involving a greater degree of scrutiny of the factual assumptions underlying the legislation. See L. Tribe, American Constitutional Law § 16.30, at 1082-83 (1978).
Assuming the applicability of a more stringent, intermediate level of scrutiny in some cases, commentators have noted that its application appears to have been limited by the Supreme Court to cases involving "a quasi-fundamental right or an 'almost’ suspect classification.”
E.g.
Redish,
Legislative Response to the Medical Malpractice Insurance Crisis: Constitutional Implications,
55 Tex.L.Rev. 759, 773 (1977). Moreover, even the approach advocated by Mr. Justice Marshall, that of evaluating the interest infringed and applying an appropriate sliding scale level of scrutiny,
see, e.g., City of Cleburne v. Cleburne Living Center,
— U.S. —, —,
. Examining the other cases cited by the plaintiff, in
Johnson v. St. Vincent Hospital, Inc.,
*1030
Arneson v. Olsen,
. The Act established a voluntary procedure for the review of malpractice claims by an "advisory panel,” 24 M.R.S.A. §§ 2801-2809, and a procedure for the voluntary submission of malpractice claims to binding arbitration, 24 M.R.S.A. §§ 2701-2715 (repealed effective Jan. 1, 1983).
The panel review procedure provides for the submission of cases as follows:
§ 2803. Submission of cases 1. Written requests; signatures; content. Any attorney may submit a case of asserted medical malpractice for the consideration of the panel by a request in writing signed by both the party and his attorney and delivering the original and 6 copies thereof to the chairman of the panel. This written request shall contain the following:
A. A brief statement of the facts of the case, showing the persons involved, the dates and the circumstances, so far as they are known, of the alleged act or acts of malpractice;
B. A statement authorizing the рanel, by its chairman, to obtain all medical and hospital records and information pertaining to the incident complained of, which statement shall be accompanied by true copies of any and all medical and hospital records then in the possession of said party or his attorney, and which, for only the purpose of the panel’s consideration of the matter, waives privilege as to the contents of such records. The statement shall not be construed as waiving the privilege for any other purpose or any other contest, in or out of court;
C. A statement that the deliberations and the discussions of the panel and of any member of the panel in the deliberation of the case shall be confidential and privileged, and that no panel member will be asked in any action to testify concerning the deliberations, discussions and internal prоceedings of the panel;
D. A statement that the party or attorney understands and subscribes to the purpose of *1032 screening medical malpractice cases and has advised his client thereof and that the client agrees to the submission of the facts pursuant to the plan;
E. A request that the panel consider the merits of the claim and render its report. 2. Notice to physician; agreement; waiver. Upon receipt of the request, the chairman shall immediately forward a copy to the physician involved who, if he agrees to the submission, shall forthwith forward to the chairman a statement as provided in subsection 1, paragraphs B, C, D and E. Neither the party making the original request pursuant to subsection 1 nor his attorney shall be bound by any waiver or agreement made thereunder until the chairman shall have received from the physician a like written waiver or agreement.
24 M.R.S.A. § 2803 (emphasis added). As presently worded, the statute appears to contemplate the submission of requests for review by claimants alone, rather than by either claimants or physicians.
. In response to defendants’ suggestion at oral argument on June 24, 1983 that Givertz mandated dismissal of the complaint, both parties, pursuant to court order, filed supplemental memoranda dated July 15, 1983 and reply memoranda dated July 29, 1983. No mention was made of plaintiff’s constitutional challenge to 14 M.R. S.A. § 753 until the issue was raised in his reply brief.
. In
Clark v. Gulesian, supra,
the First Circuit held that the application of Maine’s medical malpractice statute of limitations to bar a "foreign-object” malpractice action not commenced within two years of the date of the surgery in question, as required under the then-existing rule defining the point when a cause of action "accrues,”
Tantish v. Szendey,
the state may reasonably rеcognize that a defendant has an interest in repose, and in the avoidance of stale claims, however free from fault the claimant’s delay may be. Such a conclusion does not deprive the plaintiff of any constitutional right to fair or equal treatment.
Id. at 406.
Fitz v. Dolyak, supra, rejected an equal protection challenge to an Iowa statute which limits, to six years from the date of the negligent act, the period for bringing medical malpractice claims involving diagnosis and treatment while applying no such limitation to "foreign-object” malpractice cases, the latter being maintainable within two years of the time the injury should have been discovered without regard to the six-year statute of repose. The court found that the provision of a potentially longer period for bringing "foreign-object” cases is rational because such claims are more easily verified even with the passage of time, while other malpractice claims are more apt to become stale.
