Unserved Medical Malpractice Complaints Cannot Be Saved by Relation-Back; Unjust Enrichment/Rescission Claims Against Memory-Care Facilities Are Not “Medical Malpractice”

1. Introduction

In Estate of Athy v. Edgewood (2026 MT 3), the Montana Supreme Court reviewed the dismissal of claims brought by Alex Athy, individually and as personal representative of the Estate of Terry Athy, against a memory-care operator and related entities (collectively, Edgewood/Defendants). Terry Athy, a dementia patient, resided at the facility beginning in June 2021 and died on November 23, 2021 after infection-related complications.

The litigation posture was procedurally unusual but increasingly common in time-limit disputes: Athy filed a timely original complaint in November 2023 but never served it. Nearly a year later, he filed a “First Amended Complaint” (FAC) in November 2024, again without serving. Defendants moved to dismiss based on (a) medical-malpractice characterization, (b) Montana’s two-year medical-malpractice limitations period in § 27-2-205(1), MCA, and (c) the six-month service requirement in § 25-3-106, MCA.

The Supreme Court addressed two core issues: (1) which counts were “medical malpractice” subject to the medical-malpractice time-and-service regime, and (2) whether the malpractice-based counts were time-barred notwithstanding Athy’s arguments for tolling and relation-back.

2. Summary of the Opinion

  • Counts I–VI (wrongful death, survival, negligence, NIED, IIED, elder abuse) were properly treated as medical malpractice claims against a “long-term care facility,” subject to § 27-2-205(1), MCA (two-year limitations period) and § 25-3-106, MCA (service within six months).
  • Those malpractice counts were properly dismissed as time-barred under Estate of Phillips v. Robbins because the original complaint was never served, the limitations period expired, and the later FAC could not revive the case.
  • Counts VII–VIII (unjust enrichment and rescission of contract) were not medical malpractice claims and therefore were not subject to §§ 27-2-205(1) or 25-3-106, MCA. Their dismissal on medical-malpractice timeliness grounds was reversed.
  • The Court affirmed in part, reversed in part, and remanded for further proceedings only on unjust enrichment and contract rescission.

3. Analysis

A. Precedents Cited

1) Defining and identifying “medical malpractice” (substance over labels)

  • Camen v. Glacier Eye Clinic, P.C. and Kipfinger v. Great Falls Obstetrical & Gynecological Assocs.: The Court relied on these decisions to frame medical malpractice as a “species of negligence” and “professional negligence applicable to health care providers,” typically requiring expert testimony on duty, breach, and causation. This supported the Court’s focus on whether Athy’s care-based allegations turned on professional standards beyond lay knowledge.
  • Labair v. Carey, Selensky-Foust v. Mercer, and Montana Deaconess Hosp. v. Gratton: These authorities anchored the Court’s view that where claims are “medical in nature” and require professional standard-of-care proof, they sound in malpractice (and generally require expert testimony), even if pleaded as ordinary negligence or other torts.
  • Tin Cup Cnty. Water v. Garden City Plumbing & Heating, Inc., Saucier v. McDonald's Rests. of Mont., Inc., and Erickson v. Croft: These cases supply the “gravamen” framework—courts apply the limitations period based on the true nature of the claim, not the plaintiff’s label. That doctrine was central to recharacterizing Counts I–VI as malpractice.
  • Out-of-state persuasive authorities cited by the Court—Bryant v. Oakpointe Villa Nursing Ctr., Inc., Szymborski v. Spring Mt. Treatment Ctr., and Ditch v. Waynesboro Hosp.—reinforced the distinction between professional medical judgment/treatment claims (malpractice) and non-medical, administrative, or premises-type claims (ordinary negligence).

2) Interplay between the MMLPA and medical-malpractice time/service statutes

  • Linder v. Smith and Pickett v. Cortese: These cases supplied background principles about the Montana Medical Legal Panel Act (MMLPA) as a screening mechanism and its “condition precedent” role for claims within its defined scope. The Court used them to explain what the MMLPA does (panel review) and does not do (define the full universe of malpractice actions).
  • Northwestern Corp. v. Mont. Dep't of Pub. Serv. Regulation and § 1-2-106, MCA: Cited for interpretive methodology—use statutory definitions and technical meanings where provided.
  • City of Missoula v. Fox and the “absurd results” canon: The Court invoked holistic, plain-language construction to reject Athy’s argument that only MMLPA-panel-eligible claims can be subject to §§ 27-2-205(1) and 25-3-106, MCA. Because § 27-2-205(1), MCA lists professionals not covered by the MMLPA definition of “health care provider,” tying the malpractice limitations period to MMLPA eligibility would create an incoherent statutory scheme.

3) Defining “long-term care facility” for § 27-2-205(1), MCA

  • § 1-2-107, MCA: The Court applied this cross-statute definition principle to borrow a definition where a term is undefined in the statute at issue.
  • State v. Pinder: Used to support careful reading of prefatory definitional language and when definitions can be imported across contexts.
  • Judicial Stds. Comm'n v. Not Afraid and Dep't of Revenue v. Gallatin Outpatient Clinic: These decisions supported referencing definitions in § 50-5-101, MCA outside Title 50 when the definitional structure does not clearly forbid it. This paved the way for treating the memory-care facility—based on pleaded services—as a “long-term care facility” under § 27-2-205(1), MCA.
  • Clark Fork Coalition v. Mont. Dep't of Natural Res. & Conservation: Cited for the presumption that the Legislature is aware of its enactments; used to contextualize how older and newer statutes fit together.

4) Service of process, dismissal effects, tolling, and the Phillips line

  • Estate of Phillips v. Robbins: The controlling precedent for the procedural outcome of Counts I–VI. It held that failure to serve within § 25-3-106, MCA triggers dismissal and does not toll the statute of limitations; a later refiled complaint after limitations expires is time-barred, and “without prejudice” offers no practical rescue once limitations has run.
  • Peterson v. Simon: Distinguished in the opinion to clarify that § 25-3-106, MCA mandates dismissal without prejudice when dismissal rests solely on service delay. In Athy, however, the later “amended” filing re-triggered the statute-of-limitations problem addressed in Estate of Phillips v. Robbins.
  • Fonk v. Ulsher, Nolan v. Riverstone Health Care, and La Forest v. Texaco: These anchored the Court’s insistence on strict service rules—actual knowledge is not a substitute for valid service—and that notice of a claim differs from notice of a lawsuit.
  • Schmitz v. Engstrom and the “as if the suit had never been brought” formulation: Used to explain the consequence of dismissal without prejudice in limitations analysis.
  • Schmitz v. Vasquez: Invoked by Athy for merits-based policy; the Court (as in Estate of Phillips v. Robbins) treated it as subordinate to the Legislature’s clear policy choice for tighter malpractice deadlines.
  • Harris v. Canton: Cited (via Phillips) for the limited nature of tolling when an action is dismissed without prejudice.

5) Tolling arguments under Webb and panel-review “bridge” tolling

  • Webb v. T.D.: The Court treated Webb as narrowly fact-specific. It allowed continuous tolling where statutory panel-review tolling operated as a “bridge” between a first complaint and a subsequent complaint while panel proceedings were pending. Athy had no such panel-review tolling (the MMLPA was inapplicable), so Webb could not save his claims.
  • Tietjen v. Heberlein: Referenced within the Webb discussion regarding the general rule that voluntary dismissals do not toll limitations.

6) Relation-back doctrine depends on notice achieved through service

  • Rozan v. Rosen and Rierson v. State: These cases supplied the Court’s key relation-back principle: Rule 15(c) is grounded in notice of litigation, and where the original pleading was never served, relation-back “will not operate.”
  • Prentice Lumber Co. v. Hukill: Used to explain when amendments can relate back—when the original pleading gave fair notice of the general factual situation.
  • Keller v. Stembridge Gun Rentals: Reinforced that relation-back does not permit adding/substituting parties who had no notice of the original action.

B. Legal Reasoning

1) The MMLPA does not define the universe of “medical malpractice” for limitation/service rules

Athy’s primary statutory move was to argue that if his claims were not “malpractice claims” subject to MMLPA panel review, then they could not be subject to the medical-malpractice limitations period or special service deadline. The Court rejected that as incompatible with the text and structure of Montana law:

  • The MMLPA applies only to a defined set of “health care providers” and explicitly excludes a “residential care facility” from that definition. Based on the pleaded facts, Edgewood was an assisted living facility/adult day care center—falling within “residential care facility”—so the MMLPA did not apply.
  • But § 27-2-205(1), MCA covers “actions for medical malpractice” against a broader set of professionals and entities than the MMLPA’s coverage. Therefore, MMLPA inapplicability does not imply malpractice-time-limit inapplicability.

2) Edgewood qualifies (as pleaded) as a “long-term care facility” for § 27-2-205(1), MCA

Because § 27-2-205(1), MCA does not define “long-term care facility,” the Court used § 1-2-107, MCA to borrow the definition from § 50-5-101(31), MCA, reasoning that Title 50’s definitional prefatory language did not prohibit cross-context use. It then compared the pleaded services (bathing, toileting, feeding, medicating, bed sore prevention and treatment, wound care) to Title 50’s “personal care” and “activities of daily living” framework and held that Edgewood, on the face of the FAC, fit the “long-term care facility” category for malpractice limitations purposes.

3) Gravamen analysis: Counts I–VI are malpractice; Counts VII–VIII are not

Applying Tin Cup Cnty. Water v. Garden City Plumbing & Heating, Inc. and Saucier v. McDonald's Rests. of Mont., Inc., the Court distinguished claims turning on professional standards of care from claims aimed at business practices:

  • Counts I–VI: Alleged failures in documenting/treating wounds, medication availability, seeking higher-level treatment, training/supervision, and maintaining patient-care documentation—causally tied to infection, complications, and death. These allegations, in the Court’s view, necessarily implicate professional medical judgment and require expert testimony, placing them in “medical malpractice” despite labels like negligence, wrongful death, or elder abuse.
  • Counts VII–VIII: Unjust enrichment (retaining payments for “non-existent care”) and rescission (alleged misrepresentations inducing the contract) were treated as claims about financial transactions and contract formation/remedies rather than the adequacy of medical judgment. The Court analogized to Selensky-Foust v. Mercer in distinguishing professional-care questions from “general business decisions.”

4) Why the malpractice claims were time-barred: Phillips controls; no tolling; no relation-back without service

Once Counts I–VI were categorized as malpractice, the procedural failure to serve became dispositive. Under § 25-3-106, MCA, a plaintiff “shall” accomplish service within six months. Athy never did. The Court then applied Estate of Phillips v. Robbins to hold:

  • Dismissal without prejudice for failure to timely serve does not extend or toll the two-year limitations period in § 27-2-205(1), MCA.
  • Once limitations expires, “without prejudice” is practically meaningless—the plaintiff may be left with no timely action to refile.

The Court also resolved the open “relation-back” question left undecided in Phillips. Relying on Rierson v. State and La Forest v. Texaco, it held that relation-back depends on notice of litigation, which in Montana is achieved through service; therefore, an unserved original complaint provides no Rule 15(c) anchor. In the Court’s phrasing, dismissal leaves the matter “as if the suit had never been brought,” meaning there was no operative “original pleading” to which the FAC could relate back.

C. Impact

1) Practical consequences for plaintiffs suing assisted living/memory-care operators

This decision clarifies that a memory-care operator can qualify as a “long-term care facility” for medical-malpractice limitation purposes even if it is not a MMLPA “health care provider.” That alignment expands the reach of the two-year malpractice limitations period in § 27-2-205(1), MCA to settings that may be pleaded as “custodial” care but that include medicating, wound care, and other health-related services.

2) Service-of-process discipline is outcome-determinative in malpractice cases

The Court effectively reinforces a hard litigation reality: in malpractice actions, the plaintiff must not only file within two years but must also serve within six months under § 25-3-106, MCA, or risk losing the case entirely once the limitations period runs. The opinion cements that:

  • Filing alone will not preserve a malpractice claim if service is not completed and limitations expires.
  • Relation-back under M. R. Civ. P. 15(c) cannot be used to bypass the notice function of service.

3) Claim-splitting incentives: business-practice claims may survive even when malpractice claims fail

By holding unjust enrichment and rescission are not malpractice, the Court signals a meaningful pathway for plaintiffs to pursue non-injury, transaction-focused remedies (restitution/rescission) even where personal-injury malpractice claims are procedurally barred. This may reshape pleading strategy, particularly in long-term care disputes involving allegations of overbilling, misrepresentation, or payment retention.

4. Complex Concepts Simplified

  • “Gravamen”: The court looks at what the claim is really about (professional medical care vs. something else), not the label the plaintiff uses.
  • MMLPA vs. “medical malpractice” statutes: The MMLPA is a pre-suit screening process for a limited set of defendants; it does not define all lawsuits that count as “medical malpractice” for limitation and service rules.
  • Statute of limitations vs. service deadline: A limitations period sets the latest date to file; the service deadline sets how quickly the defendant must be formally served. Missing either can end the case.
  • “Dismissal without prejudice”: It means the claim is not decided on the merits and can be refiled—but only if the statute of limitations is still open.
  • “Relation-back” (M. R. Civ. P. 15(c)): Later pleadings can sometimes be treated as if filed earlier, but only when the defendant had timely notice of the lawsuit. In Montana, an unserved complaint generally cannot supply that notice.

5. Conclusion

Estate of Athy v. Edgewood establishes two important clarifications in Montana civil practice involving long-term care litigation: (1) claims challenging the adequacy of memory-care services—wound care, medication management, monitoring, and treatment decisions—are “medical malpractice” governed by § 27-2-205(1), MCA and the strict six-month service requirement in § 25-3-106, MCA; and (2) plaintiffs cannot use M. R. Civ. P. 15(c) relation-back to revive malpractice claims where the original complaint was never served, because notice through service is foundational to relation-back. At the same time, the Court preserves room for non-malpractice theories—like unjust enrichment and rescission—aimed at financial and contractual misconduct rather than professional standards of medical care.
