Summary Judgment: Courts Must Preserve Genuine Factual Disputes
Montell v. Diversified Clinical Servs. Inc., 757 F.3d 497 (6th Cir. 2014), supplied de novo review: the appellate court independently assessed whether summary judgment was appropriate.
Anderson v. Liberty Lobby, Inc., 477 U.S. 242 (1986), supplied the governing distinction between material factual disputes and issues that cannot affect the outcome. Evidence must permit a reasonable jury to find for the nonmoving party. Judge Bush also invoked this decision to emphasize Horton’s obligation to produce affirmative evidence of subjective knowledge.
Chapman v. UAW Local 1005, 670 F.3d 677 (6th Cir. 2012) (en banc), required favorable reasonable inferences for the party opposing summary judgment. This principle directly influenced the majority’s assessment of what Dr. Guerrant knew about Horton’s immobility and the status of the MRI.
Taft Broad. Co. v. United States, 929 F.2d 240 (6th Cir. 1991), quoting Mingus Constructors, Inc. v. United States, 812 F.2d 1387 (Fed. Cir. 1987), explained that cross-motions do not eliminate this protection. Each motion must be evaluated separately, drawing appropriate inferences against the party seeking judgment.
The Constitutional Framework and State Action
Shadrick v. Hopkins County, 805 F.3d 724 (6th Cir. 2015), quoting Jones v. Muskegon County, 625 F.3d 935 (6th Cir. 2010), identified the two basic elements of a § 1983 claim: deprivation of a federally protected right and causation by a person acting under color of state law. Shadrick v. Hopkins County also supported individualized responsibility and supplied the framework for assessing Centurion’s alleged supervisory and training failures.
West v. Atkins, 487 U.S. 42 (1988), established that medical professionals providing state prison healthcare act under color of state law even when they are contractors rather than public employees. Outsourcing therefore did not remove the individual defendants’ conduct from constitutional scrutiny.
Estelle v. Gamble, 429 U.S. 97 (1976), established that deliberate indifference to serious prisoner medical needs can violate the Eighth Amendment. Farmer v. Brennan, 511 U.S. 825 (1994), supplied the controlling objective and subjective requirements: a substantial risk of serious harm and an official’s actual awareness and disregard of that risk.
Farmer v. Brennan was particularly important because it permits subjective knowledge to be proved circumstantially, including through an obvious risk. It also prevents officials from avoiding liability by refusing to confirm facts or inferences they strongly suspect. The majority and dissent agreed on this doctrinal foundation but disagreed about whether Horton’s evidence supported the necessary inference.
Cockrun v. Berrien County., 101 F.4th 416 (6th Cir. 2024), supported the court’s conclusion that the individual defendants forfeited qualified immunity by failing to invoke it in their summary-judgment motion. The appeal therefore did not turn on whether the relevant constitutional rule was clearly established.
Objective Seriousness and the Role of Medical Evidence
Blackmore v. Kalamazoo County, 390 F.3d 890 (6th Cir. 2004), was the majority’s central authority. A medical need is sufficiently serious when a physician has diagnosed it as requiring treatment or when its need for medical attention would be obvious to a layperson.
Blackmore v. Kalamazoo County also limited the verifying-medical-evidence requirement discussed in Napier v. Madison County, 238 F.3d 739 (6th Cir. 2001). Such evidence is relevant to minor ailments or nonobvious complaints; it is not an additional prerequisite when the need for prompt medical attention is apparent. The majority cited Griswold v. Trinity Health Mich., 175 F.4th 706 (6th Cir. 2026), as a recent reaffirmation of that approach.
The opinion used Howell, 67 F.4th at 312, as an analogy involving inability to walk, falls, numbness, back and leg pain, and severe reported pain. It relied on Garretson v. City of Madison Heights, 407 F.3d 789 (6th Cir. 2005), for circumstances involving emergency hospitalization, and Adkins v. Morgan County, 798 F. App’x 858 (6th Cir. 2020), for a spinal infection accompanied by inability to move the legs. The supplied opinion identifies Howell only by its shortened title.
Rhinehart v. Scutt, 894 F.3d 721 (6th Cir. 2018), created the principal doctrinal difficulty. The district court relied on its statement requiring care sufficiently grossly incompetent, inadequate, or excessive to shock the conscience or offend fundamental fairness.
The majority traced that language to Miller v. Calhoun County, 408 F.3d 803 (6th Cir. 2005), and rejected its use as an additional objective burden. In the majority’s reading, Miller v. Calhoun County described gross inadequacy as an alternative evidentiary route, not something a plaintiff must prove in addition to a serious medical need. Santiago v. Ringle, 734 F.3d 585 (6th Cir. 2013), supported the continued separation of the established components. Est. of Majors v. Gerlach, 821 F. App’x 533 (6th Cir. 2020), had already questioned why Rhinehart v. Scutt placed that language within the objective component.
This reasoning clarifies the analytical framework without eliminating the separate obligation to prove subjective deliberate indifference.
Subjective Recklessness and Ineffective Treatment
Comstock v. McCrary, 273 F.3d 693 (6th Cir. 2001), organized the subjective inquiry into perception of relevant facts, actual inference of substantial risk, and disregard of that risk. It also supplied the dissent’s warning against turning medical malpractice into a constitutional claim.
Santiago v. Ringle reinforced that deliberate indifference requires more than negligence but does not require a purpose to harm. The opinion also relied on Dominguez, 555 F.3d at 550–51, for the proposition that awareness of serious risk does not require knowledge of the precise diagnosis or the exact injury that ultimately occurs. The supplied text gives only that shortened case title.
Darrah v. Krisher, 865 F.3d 361 (6th Cir. 2017), provided the closest treatment analogy. There, providers continued an ineffective medication for a worsening skin condition despite repeated complaints and knowledge of associated risks. Whether continuing that treatment was reasonable was a jury question. The majority applied the same principle to continued pain treatment despite Horton’s deterioration.
The dissent relied on Westlake v. Lucas, 537 F.2d 857 (6th Cir. 1976), to distinguish deliberate indifference from disagreement over medical judgment. It also cited Phillips v. Tangilag, 14 F.4th 524 (6th Cir. 2021), in arguing that ordering an MRI facially satisfied the physician’s obligations absent evidence that he knew waiting was inadequate.
Corporate Liability and Adequate Appellate Presentation
Monell v. Department of Social Services of City of New York, 436 U.S. 658 (1978), supplied the policy-or-custom requirement for entity liability. Johnson v. Karnes, 398 F.3d 868 (6th Cir. 2005), extended the relevant framework to private entities performing traditional governmental functions such as prison healthcare.
Burgess v. Fischer, 735 F.3d 462 (6th Cir. 2013), identified four potential routes: an unlawful official policy, ratification by a final decisionmaker, inadequate training or supervision, and a custom tolerating federal-rights violations.
Shadrick v. Hopkins County explained that inadequate-training liability may rest on a pattern of similar violations or, in limited circumstances, a single violation involving deficient preparation for recurring situations presenting an obvious constitutional risk. Horton did not substantiate that latter theory with evidence about Centurion’s training.
Finally, United States v. Elder, 90 F.3d 1110 (6th Cir. 1996), supported the court’s refusal to construct an argument from a perfunctory appellate presentation. That deficiency allowed the court to affirm without deciding whether Horton had preserved the particular theory below.
B. Legal Reasoning Applied to Horton’s Claims
The Objective Question Concerns the Medical Need, Not Merely the Quality of Care
The majority’s most important analytical move was to separate the seriousness of Horton’s condition from the constitutional culpability of its treatment. Inability to stand or walk, extreme pain, progressive neurological impairment, and alarming imaging findings established an obvious need for medical attention.
Accordingly, the district court should not have rejected the objective component merely because it considered the treatment insufficiently shocking or grossly inadequate. A prisoner with an obvious serious medical need does not lose that classification because providers performed examinations, prescribed medication, or ordered tests.
Horton also supplied expert evidence beyond what the majority considered necessary to establish obviousness. Dr. Johnny Bates testified that the X-rays warranted emergency imaging and hospitalization and that hospital transfer between December 5 and December 19 would have prevented paralysis. This evidence supplied an alternative basis for satisfying the medical-evidence concern and supported the claimed consequences of delay.
The opinion does not, however, create a universal exemption from expert evidence. Its holding concerns the objective seriousness requirement; other issues, including medical causation or state-law negligence, may present separate evidentiary questions.
The Claim Against Dr. Guerrant Depended on Accumulating Warning Signs
The majority did not treat pain complaints alone as sufficient proof of deliberate indifference. It assessed their combination with new thoracic symptoms, deteriorating mobility, ineffective conservative treatment, and imaging suggesting dangerous pathology.
The October MRI denial mattered because the majority found evidence that the requested conservative measures had already been undertaken. A jury could question why the request was not promptly supplemented rather than delayed until late November. By December 8, moreover, Dr. Guerrant had been told that Horton arrived in a wheelchair and had received the concerning X-ray findings.
The district court had drawn favorable inferences for the physician concerning his knowledge of the MRI’s approval and the extent of Horton’s immobility. The majority held that the summary-judgment standard required the opposite approach. His testimony permitted an inference that he did not know whether the MRI had been approved or scheduled, while the nurse’s telephone report supported awareness of severe mobility loss.
From those facts, a jury could infer that he recognized a substantial risk yet failed to expedite imaging, arrange emergency evaluation, or otherwise escalate treatment. The absence of a confirmed infection diagnosis did not foreclose liability: the relevant knowledge was awareness of serious danger, not certainty about its precise cause.
Nor did the existence of some treatment necessarily resolve the claim. Under the majority’s application of Darrah v. Krisher, knowingly persisting in ineffective care can present a constitutional issue even when the record contains repeated medical encounters.
The Claim Against N.P. Hendrix Labonte Required Independent Proof
The court declined to attribute Dr. Guerrant’s potential deliberate indifference to the nurse practitioner. Her documented involvement included evaluations, symptom documentation, medication, referrals, and collaboration concerning imaging. Horton did not adequately identify those actions as independently establishing the required subjective disregard.
This was an individualized evidentiary conclusion, not a rule insulating nurse practitioners who work with physicians. Shared participation in treatment neither automatically establishes nor automatically defeats liability. Each defendant’s knowledge and conduct must be proved separately.
The Claim Against Centurion Failed for Lack of Supported Institutional Causation
Horton argued that inadequate supervision caused the December 11 request reporting loss of leg function not to reach his providers. But an unsuccessful communication, even one with devastating consequences, does not by itself establish a constitutionally defective corporate policy.
Because Horton identified only his own episode, he needed a developed evidentiary basis for the limited single-incident route. His brief did not identify record evidence about Centurion’s training for processing sick-call requests. The claim therefore failed without a decision that every single-incident claim is legally insufficient.
The opinion also did not hold that the MRI authorization process itself established an unconstitutional corporate policy. Criticism of the physician’s response to a denial remained distinct from proof of institutional liability.
Reviving a Federal Claim Reopened the Supplemental-Jurisdiction Question
The district court’s stated reason for declining the state claims was that no federal claim remained. Reinstatement of the claim against Dr. Guerrant removed that premise. The appellate court therefore vacated the jurisdictional dismissal and directed reconsideration.
It did not decide the merits of Tennessee medical negligence or require the district court to retain those claims. Nor did it disturb the separate sovereign-immunity dismissals of TDOC and the prison.
C. The Partial Dissent: Risk Awareness or Negligent Medical Judgment?
Judge Bush’s disagreement exposed the boundary between recklessness and malpractice. In his view, evidence that the physician should have recognized an emergency did not establish that he actually recognized one.
The dissent emphasized three points: an MRI had been ordered; the X-ray report did not expressly direct emergency action; and Dr. Guerrant testified that he believed Horton’s condition had not changed and did not consider the situation urgent. Judge Bush therefore found no affirmative evidence that the physician knew waiting for imaging was inadequate.
He also challenged the majority’s treatment of the chronology. In particular, he disputed any suggestion that the new symptoms prompting the October MRI had already appeared in June, stressing the record’s description of sporadic symptoms and normal functioning between episodes.
The majority’s answer was that subjective knowledge can be inferred from circumstances, including known deterioration and alarming test results. A physician’s denial of urgency does not necessarily eliminate a factual dispute when other evidence permits a contrary inference.
The disagreement was thus principally about evidentiary sufficiency, not the governing constitutional test. The majority found enough evidence for a jury; the dissent viewed the same record as showing, at most, a potentially negligent assessment of urgency.
D. Potential Impact
- Clearer separation of the two components: Courts should not impose an additional treatment-quality threshold before recognizing an obvious serious medical need.
- Attention to changing symptoms: A chronic diagnosis does not conclusively explain later functional decline or new anatomical complaints.
- No automatic protection from ordering a test: Depending on the known circumstances, failure to expedite an already requested test may remain relevant to deliberate indifference.
- Greater importance of contemporaneous records: Notes, telephone communications, imaging reports, authorization records, and mobility observations can establish what a provider actually knew.
- Continued limits on liability: A poor outcome, incorrect diagnosis, or treatment disagreement still does not automatically establish an Eighth Amendment violation.
- Separate proof for separate defendants: Claims against another clinician or a healthcare corporation require evidence beyond a treating physician’s alleged wrongdoing.
Because the opinion is unpublished, its significance is principally persuasive and explanatory. Its treatment of the tension between Blackmore v. Kalamazoo County and language in Rhinehart v. Scutt is nevertheless important for future arguments about the proper objective standard.
