Distinct Medical-Theory Amendments Do Not Relate Back Under Florida Law in § 1983 Actions (and Unchallenged Dismissal Grounds Are Fatal on Appeal)

1. Introduction

Margherita Cunningham v. Centurion of Florida, LLC is an unpublished, per curiam Eleventh Circuit decision affirming dismissal of a prisoner-medical-care suit brought under 42 U.S.C. § 1983. The plaintiff, Ray Cunningham, alleged unconstitutional medical care while in Florida state prison. After his death, his estate (through personal representative Margherita Cunningham) continued the litigation against Centurion of Florida, LLC, the prison medical provider.

The appeal presented two practical appellate and pleading problems that frequently decide § 1983 cases without reaching the merits:

  1. Appellate forfeiture: the estate did not challenge one independent ground for dismissal (failure to state a deliberate-indifference claim), requiring affirmance under Eleventh Circuit briefing rules.
  2. Limitations and relation back: the estate’s later amendment shifted from a “breathing/pneumonia” theory to a “hepatitis C delay causing liver cancer” theory; the court held the latter claim did not relate back under Florida’s relation-back doctrine and was time-barred.

2. Summary of the Opinion

The Eleventh Circuit affirmed the dismissal of the estate’s second amended complaint on two key bases:

  • Forfeiture: because the estate did not argue on appeal that the complaint stated a valid deliberate-indifference claim, it forfeited review of that independent dismissal ground, which alone required affirmance.
  • Time bar (alternative holding): even if forfeiture were overlooked, the hepatitis C/liver cancer theory filed in May 2025 was barred by Florida’s four-year statute of limitations for § 1983 actions, and it did not relate back to the original 2021 complaint because the factual scenario and injury differed.

3. Analysis

3.1 Precedents Cited

Standard of review and procedural framework

  • Butler v. Sheriff of Palm Beach Cnty., 685 F.3d 1261 (11th Cir. 2012): supplied the familiar de novo standard for reviewing a dismissal, taking allegations as true and construing them in the plaintiff’s favor.
  • Harrison v. Digit. Health Plan, 183 F.3d 1235 (11th Cir. 1999) and Mungin v. Sec'y, Fla. Dep't of Corr., 89 F.4th 1308 (11th Cir. 2024): confirmed de novo review for statute-of-limitations application and for relation-back determinations. Their role is methodological: the panel signaled it owed no deference to the district court’s legal conclusions.

Appellate forfeiture and “independent ground” affirmance

  • United States v. Campbell, 26 F.4th 860 (11th Cir. 2022) (en banc): provided the governing rule that failing to raise an issue in an initial appellate brief constitutes forfeiture. The panel used Campbell to treat the estate’s silence on deliberate indifference as dispositive.
  • Sapuppo v. Allstate Floridian Ins. Co., 739 F.3d 678 (11th Cir. 2014): supplied the crucial “independent ground” doctrine: if an appellant fails to properly challenge one ground supporting the judgment, affirmance follows. This case often functions as a “briefing gatekeeper,” and it did so here.

Limitations, relation back, and the role of state law

  • Chappell v. Rich, 340 F.3d 1279 (11th Cir. 2003): established that § 1983 borrows the forum state’s residual personal injury limitations period—four years in Florida. The panel treated this as settled law and moved directly to relation back.
  • Caron v. NCL (Bah.), Ltd., 910 F.3d 1359 (11th Cir. 2018) (citing McCurdy v. United States, 264 U.S. 484 (1924)): framed relation back as a “legal fiction” meant to prevent unjust limitations outcomes. This framing set up the court’s explanation that the fiction has boundaries—especially where the amendment changes the factual scenario.
  • Saxton v. ACF Indus., Inc., 254 F.3d 959 (11th Cir. 2001) (en banc): was central to the mechanics of the decision. The panel relied on Saxton’s interpretation of Fed. R. Civ. P. 15(c)(1)(A): when state law supplies the limitations period, state law relation-back rules can control even if federal relation back would not.
  • Kopel v. Kopel, 229 So. 3d 812 (Fla. 2017): supplied the controlling Florida standard under Fla. R. Civ. P. 1.190(c). Kopel emphasizes liberal construction and allows relation back even if legal theories change—but only if the original complaint gave “fair notice of the general factual scenario or factual underpinning.” The panel used Kopel’s limiting principle (“so factually distinct”) to reject relation back.
  • Fabbiano v. Demings, 91 So. 3d 893 (Fla. Dist. Ct. App. 2012): was used as a contrast case. There, relation back was clear because the amended pleading was based on an “identical act” causing an “identical injury.” By citing Fabbiano, the panel highlighted what was missing here: factual identity between original and amended claims.

Municipal/entity liability backdrop

  • Monell v. Department of Social Services of New York, 436 U.S. 658 (1978): appeared because the district court also found the estate failed to plead that a policy/custom caused the injury. Although the panel affirmed without needing to resolve Monell pleading, the citation underscores that private medical contractors in prisons are typically evaluated through Monell-style “policy or custom” causation requirements in § 1983 litigation.

3.2 Legal Reasoning

(A) The dispositive appellate logic: forfeiture + independent ground = affirmance

The panel’s first and controlling move was procedural: the district court gave “three independent reasons” to dismiss, and the estate challenged only two (limitations and Monell) while not challenging the finding that it failed to plead deliberate indifference. Under United States v. Campbell, this omission forfeited the issue; under Sapuppo v. Allstate Floridian Ins. Co., failing to challenge one independent basis for judgment requires affirmance.

Practically, the opinion reinforces a hard appellate rule: an appellant must attack every independent dismissal rationale, or the appeal fails even if other challenged grounds are debatable.

(B) The alternative merits: why the hepatitis C theory did not relate back

The panel then explained that, even absent forfeiture, the estate would still lose because the May 2025 hepatitis C claim was time-barred. The key analytical steps were:

  1. Limitations period: Florida’s four-year residual personal injury period governs § 1983 claims in Florida federal courts (Chappell v. Rich).
  2. Accrual timing assumed against the estate: the district court treated January 2018 (when treatment began) as the latest possible accrual date, making the May 2025 amendment well outside four years. The estate did not dispute that timing on appeal; it relied on relation back.
  3. State relation-back doctrine applies: by Fed. R. Civ. P. 15(c)(1)(A) and Saxton v. ACF Indus., Inc., the court applied Fla. R. Civ. P. 1.190(c).
  4. “Fair notice” is the hinge: under Kopel v. Kopel, Florida relation back is liberal, but the original pleading must give fair notice of the factual underpinning of the later claim.
  5. Factual scenario changed materially: the original complaint focused on “breathing difficulty” and a post-release pneumonia diagnosis. The second amended complaint alleged delayed hepatitis C treatment leading to liver cancer and death. Different condition, different alleged misconduct timeframe and medical decision-making, different injury.
  6. Conclusion: because the original complaint did not give fair notice of the hepatitis C/liver cancer factual scenario, the amendment did not arise from the same “conduct, transaction, or occurrence” and therefore did not relate back.

The court’s comparison to Fabbiano v. Demings underscores the boundary: relation back is most defensible where the amended claim targets the same act and injury, not when it substitutes a new medical narrative and harm.

3.3 Impact

  • For § 1983 prisoner medical cases: the decision warns against wholesale medical-theory pivots late in litigation. If a plaintiff files timely based on one medical problem but later amends to allege a different medical condition and injury, Florida relation back may not save the new claim from the statute of limitations.
  • For pleading strategy: early complaints should capture the full factual landscape (or clearly plead alternative factual bases) where the plaintiff suspects multiple untreated conditions, because later “substitution” amendments risk being treated as new occurrences.
  • For appellate practice: the case is a reminder that Eleventh Circuit briefing rules can decide the appeal: missing any independent ground for dismissal can be outcome-determinative regardless of the strength of other arguments.
  • For defendants and case management: defendants will likely cite this decision (and its staples: Campbell/Sapuppo, Kopel) to oppose relation back where an amended complaint introduces a new medical condition, new injury, or new causal chain.

4. Complex Concepts Simplified

Deliberate indifference (Eighth Amendment)
A prison medical-care claim generally requires more than negligence or malpractice; it requires showing officials knew of and disregarded a substantial risk of serious harm. In this appeal, the court affirmed without reaching the merits because the estate did not brief the issue.
§ 1983 statute of limitations (borrowed from state law)
Federal civil-rights claims under § 1983 use the state’s personal-injury limitations period. In Florida, that period is four years.
Accrual
The date the claim “starts the clock.” The opinion assumes (for limitations analysis) that the claim accrued no later than January 2018.
Relation back
A rule that treats a later-filed amendment as if it was filed on the date of the original complaint—potentially avoiding a time bar. Under Florida’s rule, it works only when the amendment arises from the same basic factual episode and the original complaint gave fair notice of that episode.
Forfeiture on appeal
If an appellant does not argue an issue in the opening brief, the appellate court generally treats it as forfeited and will not consider it.
Independent ground for judgment
When a district court gives multiple separate reasons to dismiss, the appellant must challenge each one. If any unchallenged reason remains, the judgment stands.
Monell liability
A framework requiring proof that a policy or custom caused the constitutional violation. The district court relied on Monell as an additional dismissal ground, though the Eleventh Circuit did not need to resolve it after finding forfeiture and, alternatively, a time bar.

5. Conclusion

The Eleventh Circuit’s decision is principally a procedural and limitations-focused ruling with two clear lessons. First, under United States v. Campbell and Sapuppo v. Allstate Floridian Ins. Co., an appellant must challenge every independent dismissal ground, or affirmance is virtually automatic. Second, when Florida’s four-year limitations period governs a § 1983 claim, an amended complaint that substitutes a new medical condition and a new injury (here, shifting from breathing/pneumonia to hepatitis C delay/liver cancer) will not relate back under Kopel v. Kopel because it does not give fair notice of the same factual scenario.

In broader context, the opinion reinforces that § 1983 prison-medical litigation often turns less on constitutional theory than on careful pleading continuity, limitations discipline, and rigorous appellate issue preservation.
