Trial Forfeits Interlocutory Review of a Pretrial Qualified-Immunity Denial, Even After a Mistrial

Case: Kristian Brock and Christopher Stone v. Colton T. Hinkel, individually and as administrator of the Estate of Charles L. Hinkel, III

Court: Supreme Court of Kentucky
Decided: October 22, 2026
Disposition: Court of Appeals’ opinion vacated; case remanded to the Henry Circuit Court.

1. Introduction

This divided decision establishes an important procedural limit on Kentucky’s interlocutory review of qualified official immunity. A defendant who proceeds to trial after a denial of immunity cannot obtain review of that pretrial summary-judgment ruling merely because the notice of appeal remains within the ordinary thirty-day filing period. A subsequent mistrial does not restore that opportunity.

The decision does not extinguish the underlying immunity defense. Instead, it requires defendants seeking protection against a second trial to present immunity to the trial court on the developed trial record and, if appropriate, appeal the resulting denial.

The litigation arose from emergency treatment provided by EMT Kristian Brock and paramedic Christopher Stone to Charles L. Hinkel, III, who died after experiencing cardiac arrest. His son, Colton Hinkel, sued individually and as administrator of the estate. Although the litigation raised significant questions about emergency-service navigation policies, equipment checks, and negligence, the Supreme Court resolved the appeal on waiver and appellate-jurisdiction grounds rather than deciding whether Brock and Stone were immune or liable.

2. Background and Procedural History

The emergency response

After Hinkel experienced chest pain, his son called 911 and reported heart-attack symptoms and a history of heart attacks. Henry County EMS dispatched Brock and Stone at approximately 2:13 a.m. They used Active 911, a dispatch-linked phone application, to navigate to his home. Other available resources included a paper map book and an ambulance GPS system.

In dark, rainy conditions, they initially passed the poorly lit residence. They arrived sixteen minutes after leaving the ambulance bay; Stone estimated that difficulty locating the house caused approximately four minutes of delay.

Hinkel was taken to the ambulance, where he suffered full cardiac arrest. The ambulance’s defibrillator failed despite repeated attempts to restart it. During transport, Brock and Stone stopped at another paramedic’s home to obtain a working device and assistance. Although Stone subsequently administered five defibrillations, resuscitation efforts were unsuccessful. Hinkel was pronounced dead at the hospital.

The litigation

Date Event
September 14, 2018 Colton Hinkel sued Henry County EMS and Brock and Stone in their official and individual capacities.
January 13, 2021 The circuit court dismissed Henry County EMS and the official-capacity claims on sovereign- and governmental-immunity grounds. The individual-capacity claims remained.
August 25, 2022 Brock and Stone moved for summary judgment based on qualified official immunity.
October 11, 2022 The circuit court granted the motion in part and denied it in part, treating the map-use requirement and defibrillator-checking obligation as ministerial duties.
October 24, 2022 Trial began without an intervening interlocutory appeal.
During trial Brock and Stone twice sought directed verdicts based on qualified official immunity and causation. Both motions were denied.
November 1–4, 2022 The jury reported a deadlock on November 1. Brock and Stone appealed the October 11 summary-judgment ruling on November 2. The written mistrial order was entered November 4.

The Court of Appeals affirmed the immunity ruling. On discretionary review, the Supreme Court instead held that the appeal should not have reached the merits.

The dissent emphasized that Brock and Stone had asserted qualified immunity earlier in the litigation and had complied with the trial court’s summary-judgment schedule. The majority’s procedural account, however, treated the January 2021 dismissal as addressing sovereign and governmental immunity, not as resolving the individual-capacity qualified-immunity issue.

3. Summary of the Opinion

Justice Goodwine’s majority opinion rests on two independent grounds:

  1. Waiver by proceeding to trial. Although the notice of appeal was filed within thirty days, Brock and Stone forfeited their entitlement to interlocutory review of the pretrial immunity denial by choosing to proceed to trial.
  2. Absence of appellate jurisdiction over the challenged order. The trial record superseded the factual summary-judgment record, and the defendants’ trial-stage immunity motions produced subsequent rulings they did not appeal. The original order therefore no longer supplied the necessary basis for collateral-order review.

The Court also explained that unresolved factual questions concerning the governing navigation directive complicated immediate appellate review. It declined to decide negligence, evidentiary sufficiency, or causation because those matters fell outside the limited scope of an immunity appeal.

The majority expressly preserved the possibility of a renewed immunity motion based on the existing trial record and an appeal from a subsequent denial. The decision therefore regulates which ruling may be appealed, when, and on what record; it does not decide the ultimate immunity defense.

4. Analysis: Precedents and Legal Reasoning

A. A timely notice of appeal does not prevent waiver by conduct

Long v. Dep't of Revenue. This recent Kentucky decision supplied the starting point: immunity appeals generally follow the same temporal limits and procedural rules as other appeals. Under RAP 3(A)(1), a notice ordinarily must be filed no later than thirty days after the relevant order. Brock and Stone satisfied that requirement, but the majority treated timely filing as necessary rather than sufficient.

Long v. Dep't of Revenue also supplied a contrast. It permitted a sovereign-immunity issue to be raised in a later timely interlocutory appeal despite failure to appeal an earlier denial. Sovereign immunity, the Court explained, is waivable only by the General Assembly and may be raised for the first time on appeal. Qualified official immunity is different: it is an affirmative defense subject to ordinary procedural waiver and forfeiture.

Deaton v. Fifth Third Union Tr. Co.. This decision provided the Kentucky foundation for implied waiver. A litigant may surrender appellate rights not only by express agreement but also by conduct recognizing or acquiescing in a judgment. The majority applied that principle to the defendants’ choice to undergo the trial that an immediate immunity appeal could have interrupted.

Apostol v. Gallion. This federal precedent distinguishes two protections associated with immunity: the right to avoid trial and the right to avoid damages. A defendant may surrender entitlement to a pretrial appellate decision without necessarily losing the ability to assert immunity against damages later. That distinction is central here: proceeding to trial forfeited the particular interlocutory opportunity, not the entire defense.

English v. Dyke. This case reinforced the stage-specific nature of waiver. Failure to assert a procedural protection at the appropriate stage need not waive immunity for every purpose. The majority relied on that principle to reconcile forfeiture of pretrial appellate review with continued availability of immunity in the trial court.

Kennedy v. City of Cleveland. This decision supports the application of ordinary timing rules to immunity appeals and recognizes the trial court’s discretion over renewed immunity motions after a mistrial. Its significance is twofold: immunity does not exempt litigants from procedural discipline, and post-mistrial relief should first be sought through an appropriate ruling in the trial court.

Yanero v. Davis. The majority relied on this foundational Kentucky immunity decision for the proposition that qualified official immunity must be specifically pleaded as an affirmative defense. That feature justified treating it differently from sovereign immunity when applying waiver rules.

The resulting principle is narrower than a general loss of immunity: a defendant cannot preserve interlocutory review of the original pretrial denial simply by filing within thirty days after voluntarily proceeding through trial. Reasserting immunity in directed-verdict motions preserves opportunities to litigate the defense, but it does not preserve an appeal from an earlier ruling on a different record.

B. Why the purpose of interlocutory immunity review matters

Breathitt Cnty. Bd. of Educ. v. Prater. This decision recognizes immediate review of immunity denials because immunity protects against the burdens of defending litigation, not merely an eventual damages award. Waiting until final judgment may destroy that protection: the trial has already occurred.

Rowan Cnty. v. Sloas. Cited through Breathitt Cnty. Bd. of Educ. v. Prater, this case supplies the underlying understanding of immunity as protection from the burdens of suit. It also bears on the duty-classification issue discussed below by requiring resolution of material facts before the legal immunity determination.

Maggard v. Kinney. This case emphasizes that interlocutory immunity review is a limited exception to the normal rule requiring a final judgment. The majority used that limitation to resist converting the appeal into a general review of the defendants’ negligence arguments.

Maestas v. Lujan and Dixon v. Richer. These authorities confirm that immunity can be reasserted at and after trial once factual disputes have been resolved. They support the majority’s insistence that loss of the original opportunity to avoid trial does not eliminate every later immunity claim.

The majority’s reasoning is functional: the original appealable interest was avoiding the first trial. Once Brock and Stone underwent that trial, an appellate court could not undo its burdens. Avoiding a second trial remained a legitimate interest, but protecting that interest required a renewed ruling based on the record then available.

C. Collateral-order jurisdiction requires more than an immunity label

Commonwealth v. B.H.. This case establishes that jurisdiction is a question of law reviewed de novo. Together with Long v. Dep't of Revenue, it supports the Court’s obligation to determine its own jurisdiction before addressing the parties’ substantive arguments.

Sheets v. Ford Motor Co.. The majority applied its three-part collateral-order test. An immediately appealable order must:

  1. Conclusively decide an important issue separate from the merits;
  2. Be effectively unreviewable after final judgment; and
  3. Implicate a substantial public interest that would be imperiled without immediate review.

The October 11 order had conclusively resolved immunity on the pretrial record. But the defendants subsequently litigated immunity twice on the trial record. Those later rulings became the relevant trial-court adjudications, and the defendants did not appeal them. In the majority’s view, the original order no longer retained the characteristics that had justified its immediate review before trial.

Upper Pond Creek Volunteer Fire Dep't Inc. v. Kinser. This decision rejects the assumption that every order mentioning immunity is immediately appealable. If factual development remains necessary and the immunity question remains unresolved, the collateral-order requirement of conclusiveness is absent. The majority used it both as a general jurisdictional limit and as support for declining to resolve the disputed navigation-policy predicate itself.

Commonwealth v. Farmer. This case requires the collateral issue to be completely separate from the merits. It reinforced the concern that appellate courts should not use an immunity appeal to decide factual disputes overlapping the plaintiff’s substantive negligence case.

For the second and third collateral-order elements, the majority again focused on the particular order appealed. Immediate review of the old ruling could no longer spare the first trial. The continuing interest in avoiding retrial could be protected through a renewed motion and an appeal from its denial.

D. The trial record supersedes pretrial factual determinations

Ortiz v. Jordan. This was the principal authority for record supersession. Once a case proceeds to trial, the full evidentiary record replaces the earlier summary-judgment record as the basis for evaluating fact-dependent immunity questions. The defense remains available, but it must be assessed against the evidence actually received in court.

Dupree v. Younger. This decision supplies an essential qualification: trial supersedes pretrial factual rulings, but not purely legal conclusions. Accordingly, the majority acknowledged that a genuinely legal classification of an undisputed duty would not become unreviewable merely because evidence was later presented at trial.

That qualification prevents an overreading of the decision. The Court did not hold that every pretrial legal ruling disappears upon trial. Rather, it found that the navigation-duty issue rested on an unresolved factual predicate, while the separate waiver and jurisdictional problems also remained.

Reg'l Jail Auth. v. Tackett. This precedent limits appellate review to issues raised in or decided by the trial court. It supported requiring the circuit court to address immunity on the developed record before an appellate court undertook that task.

The Kentucky civil rules reinforced this approach:

  • CR 50.02 permits a party, when no verdict is returned, to seek judgment in accordance with a prior directed-verdict motion within ten days after the jury is discharged. The majority treated this as evidence that a deadlocked jury does not erase the trial record.
  • CR 54.02 permits revision of interlocutory orders before final judgment, allowing the trial court to reconsider immunity on an appropriate renewed motion.

The majority’s succinct response to the dissent was that a mistrial does not “unhear evidence.” Although no verdict resolved the dispute, the evidence remained available for further judicial decision-making.

E. Federal post-mistrial cases support renewed review, not review on an obsolete record

The majority and dissent agreed that immunity may be reviewed before a second trial. Their disagreement concerned the procedural route. The following authorities explain that distinction:

Precedent Role in the opinion
Spann v. Rainey The dissent relied on its rejection of automatic loss of an immunity defense or interlocutory review through failure to seek earlier dismissal. The majority distinguished it because the reviewed motion followed the first trial and the record included that trial’s transcript.
Carroll v. Ellington Recognized limited review of legal immunity questions in the specific setting of officers seeking judgment as a matter of law after a mistrial. The majority emphasized its post-trial motion posture rather than treating it as authority to revive an earlier summary-judgment appeal.
Dean v. Cnty. of Gage, Neb. Addressed renewed immunity consideration after trial and indicated that an earlier appellate legal determination should not be revisited through a Rule 50 motion without substantially different trial evidence. It illustrates the importance of identifying both the controlling prior ruling and the developed record.
Cassady v. Goering Permitted an appeal from a post-trial order rejecting immunity where retrial remained ahead. It supported the availability of later protection, but through review of a later order.
Hill v. Crum Involved a timely appeal from denial of a Rule 50(b) motion, again demonstrating review of a trial-stage ruling rather than reliance on the original summary-judgment record.
Britt v. Garcia Explained that immunity may still protect against a second trial even after the first has occurred. The majority accepted that principle but stressed that the appeal there concerned a post-verdict immunity denial.
Wilson v. City of Boston and Iacobucci v. Boulter Illustrated the trial-record focus of post-verdict immunity review, including construction of the evidence favorably to the party who prevailed at trial. Their broader relevance here was that later review uses the record produced by trial.
Johnson v. Breeden Concerned review of a judgment and denial of a new-trial motion. The dissent cited it among authorities supporting later-stage immunity review, while the majority noted its different procedural posture. The dissent also identified its abrogation on other grounds by Kingsley v. Hendrickson; that latter case supplied no independent basis for this decision.

These authorities therefore support a continuing ability to seek immunity against retrial. They do not, under the majority’s interpretation, establish a right to appellate review of a superseded factual summary-judgment ruling.

F. Duty classification requires identification of the governing directive

The navigation dispute showed why this appeal was not simply a preserved, purely legal question.

The written Map Utilization policy required familiarity with available maps, directions, and GPS systems. It also directed the non-driving crewmember to locate the destination on a map before departure or shortly afterward. The EMS director, however, testified that personnel could use the navigation method they preferred, that some ambulance GPS units did not work, and that some employees preferred Active 911.

Yanero v. Davis. A ministerial duty is absolute, certain, and imperative: it requires execution of a specified act under fixed circumstances. A sufficiently definite map-consultation requirement could therefore support ministerial classification.

Haney v. Monsky and Upchurch v. Clinton Cnty.. These cases describe discretionary duties as permitting a lawful choice among methods based on the official’s judgment. Haney v. Monsky also requires sufficient policy specificity before enforcement becomes ministerial. If the actual governing instruction permitted personnel to choose among navigation tools, the selection could instead involve discretion.

Rowan Cnty. v. Sloas. The classification is a legal question once material facts are resolved. Here, the factual predicate was not merely whether the defendants followed a clear rule; it was which directive governed their conduct.

Meinhart v. Louisville Metro Government. This decision explains that duty classification generally requires examination of the pertinent rule, policy, or regulation, not determination of whether the official complied with it. The majority distinguished that principle rather than rejecting it: the dispute here concerned identification of the pertinent directive itself. It also stressed the need for trial-court findings sufficient to permit appellate review.

This distinction is important:

  • What rule governed? A potentially disputed factual predicate.
  • Did that rule impose a ministerial or discretionary duty? A legal classification.
  • Was the duty breached, and did that breach cause injury? Questions concerning the negligence claim.

The Court did not decide that informal supervisory permission overrides a written policy. Nor did it conclusively classify use of Active 911. It identified an unresolved conflict requiring proper treatment in the trial court.

G. Negligence and causation are outside the narrow immunity appeal

Baker v. Fields. This case confines an interlocutory immunity appeal to whether immunity was properly denied. It does not authorize review of every defense to liability. Accordingly, Brock and Stone could not use this appeal to obtain a general ruling that the plaintiff’s negligence evidence was insufficient.

Morales v. City of Georgetown. This decision separates the immunity classification from whether a ministerial duty was actually breached and whether the official was negligent. Those latter issues belong to the merits and, where appropriate, the factfinder.

The defendants had not challenged the ministerial classification of the Life Pak requirements in the Court of Appeals. Their later argument about insufficient proof of negligence therefore did not present a proper immunity-classification issue. Likewise, deciding whether any delay or equipment-related breach caused Hinkel’s death would address the estate’s substantive claim rather than merely the availability of immunity.

5. The Dissent: Timely Review Should Remain Available After a Mistrial

Justice Nickell, joined by Justices Bisig and Keller, would have exercised jurisdiction. The dissent did not decide whether Brock and Stone ultimately qualified for immunity.

A. No automatic waiver from choosing trial

The dissent stressed that the defendants complied with the scheduling order, raised immunity throughout the litigation, and appealed within the original thirty-day period. The summary-judgment ruling arrived approximately two weeks before the scheduled trial. Choosing the possibility of prompt success at trial rather than the delay and uncertainty of appeal did not, in the dissent’s view, establish acquiescence or abusive manipulation.

Cabinet for Health & Fam. Servs. v. H.C.. Together with RAP 2(A)(1), RAP 3(A)(1), and Long v. Dept. of Revenue, this precedent supported the dissent’s position that a properly filed, timely notice invoked appellate jurisdiction over an otherwise appealable immunity order. The majority’s answer was that timely filing did not preserve an interlocutory entitlement lost through intervening conduct.

English v. Dyke, Skritch v. Thornton, and Guzman-Rivera v. Rivera-Cruz. The dissent understood these authorities to support waiver where defendants disregard deadlines, lack diligence, pursue dilatory tactics, or manipulate successive immunity claims. It found no such misconduct here. Guzman-Rivera v. Rivera-Cruz particularly supported use of scheduling orders to control delay.

Behrens v. Pelletier and Abney v. United States. These authorities recognize successive procedural opportunities and judicial mechanisms for screening abusive or frivolous interlocutory claims. The dissent favored targeted case-management and sanctioning measures over inferring waiver solely from proceeding to trial. The cited reference to Pearson v. Callahan qualified the continuing authority of Skritch v. Thornton on other grounds; it was not an independent basis for the dissent’s jurisdictional position.

B. Immunity protects public interests beyond the first trial

Lexington- Fayette Urb. Cnty. Gov't v. Smolcic, Pierson v. Ray, and Wyatt v. Cole. These cases supported the dissent’s emphasis that immunity serves the public and governmental functioning, not merely an official’s personal interests. Avoiding the cost and disruption of a second trial therefore remains valuable even when the first trial has already occurred.

Mitchell v. Forsyth. Its recognition of immediately appealable immunity denials underlies Kentucky’s approach in Breathitt Cnty. Bd. of Educ. v. Prater. The dissent also cited Meinhart v. Louisville Metro Gov't for extending that logic to qualified official immunity.

Gomez v. Toledo and Wells v. Com., Dep't of Highways. These decisions supported the distinction between pleaded qualified immunity and sovereign immunity that operates without a formal plea and can be waived only legislatively. The dissent accepted that distinction but maintained that Brock and Stone had properly asserted their affirmative defense.

C. The legal effect of the mistrial

Relying on secondary authorities describing a mistrial as equivalent to no trial, the dissent concluded that the parties returned to their earlier procedural position. Because the original appeal period had not expired, requiring a new immunity motion would create unnecessary duplication.

The majority rejected that account for purposes of the evidentiary record and appellate route. It accepted the continuing interest in avoiding retrial but required a renewed trial-court ruling reflecting the evidence already heard. Thus, the central division was not whether immunity can protect against a second trial, but whether a mistrial revives immediate review of the original pretrial order.

6. Complex Concepts Simplified

Qualified official immunity
A defense protecting public officials from certain individual-capacity claims arising from official conduct. Kentucky’s distinction between discretionary and ministerial duties is central to its application.
Sovereign immunity
A distinct protection associated with the state. Unlike qualified official immunity, it is not lost through ordinary litigation waiver by an individual official.
Interlocutory appeal
An appeal before the lawsuit reaches final judgment. Immunity denials may qualify because waiting could destroy the protection against undergoing trial.
Collateral-order doctrine
A narrow exception allowing immediate review of certain conclusively resolved issues that are separate from the merits and cannot adequately await final judgment.
Waiver or forfeiture of an appellate opportunity
Loss of the ability to obtain review at a particular procedural stage. Here, it did not mean permanent loss of the immunity defense.
Ministerial duty
A definite instruction requiring a particular act, rather than leaving the official a meaningful choice about how to proceed.
Discretionary duty
A task permitting judgment or a choice among lawful methods.
Superseded record
An earlier evidentiary record displaced by a fuller one. Trial evidence generally replaces the summary-judgment record for fact-dependent determinations.
Mistrial
A trial ending without a valid verdict. Under this opinion, that outcome does not erase the evidence already presented or automatically revive an earlier appeal opportunity.

7. Potential Impact

A. Defendants must make an early procedural choice

The thirty-day appeal period is an outer filing limit, not an assurance that the original immunity order remains immediately reviewable regardless of intervening events. Defendants seeking to avoid the first trial must pursue appellate review before submitting to it.

B. Post-mistrial motions become especially important

After a mistrial, defendants should identify the appropriate mechanism for a renewed immunity ruling on the existing record. The opinion specifically identifies CR 50.02 and the trial court’s authority to revise interlocutory rulings under CR 54.02. A subsequent denial may support a new interlocutory appeal; this decision does not guarantee jurisdiction over every such ruling.

C. Agencies and courts must identify the actual governing policy

The conflict between written navigation requirements and supervisory testimony demonstrates the practical importance of clear, consistent operational directives. Future courts must distinguish uncertainty about the policy’s content from disagreement about compliance with an established policy.

D. Immunity appeals remain distinct from merits appeals

The decision reinforces that denial of immunity does not establish negligence. Plaintiffs must still prove the elements of their claims, and defendants retain appropriate merits defenses. Conversely, a challenge to causation or evidentiary sufficiency does not automatically belong in an interlocutory immunity appeal.

E. The holding leaves important boundaries intact

The opinion does not extend ordinary waiver principles to sovereign immunity, erase genuinely legal pretrial rulings, establish liability for emergency responders, or prohibit protection against retrial. Its principal effect is to align the appeal with the correct procedural stage, ruling, and evidentiary record.

8. Conclusion

The Supreme Court of Kentucky held that Brock and Stone could not appeal their original pretrial qualified-immunity denial after proceeding through a trial, even though the trial ended in a mistrial and their notice was filed within thirty days.

The Court vacated the appellate affirmance without deciding immunity, negligence, or causation. Its central lesson is procedural: protection against a second trial must be sought through an appropriate renewed immunity ruling on the developed record, not by reviving review of the earlier fact-dependent summary-judgment denial.
