Charge-Specific Malicious Prosecution and the Limits of Prosecutorial Immunity

1. Introduction

This decision addresses two important limits on the dismissal of civil-rights claims arising from criminal prosecutions. First, surviving convictions do not automatically defeat a malicious-prosecution claim directed at a separate charge that ended favorably for the accused. Second, a prosecutor’s entitlement to absolute immunity depends on the function performed: personally swearing to factual allegations as a complaining witness is different from acting as an advocate.

Michael Collins Smith, a Kansas prisoner representing himself, sued the Johnson County Board of Commissioners, District Attorney Steve Howe, and assistant district attorneys Sarah Hill, Zavier Andrews, Cathy Eaton, and Julia Ronnebaum under 42 U.S.C. § 1983. The district court dismissed his second amended complaint during statutory screening. The Tenth Circuit upheld nearly all of that dismissal but reinstated the malicious-prosecution claim against Hill and Ronnebaum.

The appellate court did not find that either prosecutor violated Smith’s rights. It held that the grounds used to dismiss that narrowly defined claim did not justify its dismissal at the pleading stage.

2. Background and Procedural History

The criminal proceedings

Smith was charged in February 2017 with intentional first-degree murder of Anthony Shuster, attempted intentional first-degree murder, aggravated endangerment of Shuster’s infant daughter, and criminal possession of a firearm. In February 2019, a jury convicted him of voluntary manslaughter, attempted voluntary manslaughter, aggravated child endangerment, and criminal possession of a firearm.

The trial court designated voluntary manslaughter as the primary crime and imposed a 233-month prison sentence for that conviction. It imposed consecutive sentences of 32, 6, and 8 months for the remaining convictions, together with 36 months of post-release supervision.

On direct appeal, the Kansas Court of Appeals reversed the voluntary-manslaughter conviction because the jury should have been instructed on imperfect self-defense involuntary manslaughter as a lesser included offense. The other convictions were affirmed. The State declined to retry the reversed charge, which was dismissed with prejudice in February 2023.

Smith then opposed resentencing, arguing that he had already served the original sentences for the remaining convictions. The state trial court rejected that position, designated attempted voluntary manslaughter as the primary crime, applied his criminal history, and resentenced him to 144 months. The Kansas Court of Appeals affirmed.

The federal civil-rights action

Smith filed his federal action in January 2025. His original complaint sought $75 million in compensatory damages and $10 million in punitive damages and also challenged his continuing detention. After receiving an opportunity to amend, he filed a second amended complaint containing seven counts:

1. Malicious prosecution;
2. Deprivation of liberty without due process and denial of a fair trial;
3. Failure to intervene;
4. Civil-rights conspiracy;
5. Supervisory liability;
6. Municipal liability under Monell; and
7. Interference with family relationships.

The operative complaint sought damages but abandoned the challenge to his continuing detention. Earlier claims concerning inspection of legal mail and materials were also abandoned and were not part of the appeal.

The district court dismissed the second amended complaint under the prisoner-screening framework of 28 U.S.C. § 1915A. Its reasons included the rule of Heck v. Humphrey, deficient allegations, the supposed absence of favorable termination, absolute prosecutorial immunity, and the distinction between civil-rights litigation and habeas corpus.

3. Summary of the Opinion

The Tenth Circuit exercised appellate jurisdiction under 28 U.S.C. § 1291 and reviewed the dismissal de novo. It accepted well-pleaded factual allegations as true and assessed whether those allegations plausibly supported liability.

The remand was therefore narrow: only Count I against Hill and Ronnebaum survived. The court did not separately endorse every alternative rationale the district court had offered for dismissing the other claims.

4. Analysis: Legal Reasoning

A. Screening requires a claim-specific assessment

Statutory screening does not permit dismissal merely because a prisoner’s allegations concern a prosecution that produced valid convictions. The court must examine what each claim challenges, what success would establish, and what each defendant allegedly did.

The same basic pleading standards applicable under Federal Rule of Civil Procedure 12(b)(6) govern screening dismissals. Factual allegations receive the benefit of favorable construction, but conclusory assertions do not substitute for facts supporting liability.

B. Heck barred the trial-wide claims, not necessarily the charge-specific claim

Under Heck v. Humphrey, a plaintiff ordinarily cannot recover § 1983 damages on a theory whose success would necessarily establish the invalidity of an outstanding conviction or sentence. The relevant conviction or sentence must first have been invalidated through a recognized process.

Most of Smith’s claims attacked conduct affecting the entire trial. His fair-trial allegations, for example, asserted deliberate suppression of favorable crime-laboratory results and the suborning of perjury at the preliminary hearing and trial. The appellate court concluded that these claims effectively challenged all his convictions, including those that remained valid.

Count I was different. It alleged that prosecutors initiated and continued the intentional first-degree murder prosecution without probable cause. Because that claim focused on the charge associated with the reversed voluntary-manslaughter conviction, it did not necessarily undermine the remaining convictions. The reversal and subsequent dismissal with prejudice removed the identified Heck obstacle to that claim.

The controlling distinction was the scope of the claim, not simply the presence of both reversed and surviving convictions. The decision does not authorize plaintiffs to evade Heck by relabeling an attack on an entire criminal judgment as malicious prosecution.

C. Surviving convictions did not create a categorical malicious-prosecution bar

The district court treated Smith’s remaining convictions as defeating favorable termination. The Tenth Circuit rejected that categorical approach in light of Chiaverini v. City of Napoleon.

The relevant principle is charge-specific: valid charges do not automatically insulate an official from a Fourth Amendment malicious-prosecution claim concerning a different charge allegedly unsupported by probable cause. The continued validity of Smith’s other convictions therefore did not, by itself, justify dismissal of Count I.

This conclusion has limits. The court did not hold that reversal for instructional error proves an absence of probable cause, or that dismissal establishes all elements of malicious prosecution. It held that Smith’s other convictions were not an automatic obstacle to pursuing the terminated charge.

D. Prosecutorial immunity turns on conduct, not job title

Absolute prosecutorial immunity generally protects conduct intimately associated with the judicial process, including prosecutorial preparation and advocacy. It applies even when protected conduct is alleged to have been unlawful. The inquiry concerns the function performed, rather than the seriousness of the accusation.

Smith alleged that Ronnebaum personally swore under penalty of perjury in a charging document that he had committed premeditated murder without probable cause. He alleged that Hill similarly acted as a complaining witness in an amended charging document.

Taking those allegations as true, the court treated the prosecutors as witnesses attesting to facts rather than solely as advocates presenting the State’s case. Absolute prosecutorial immunity therefore did not justify dismissal of those portions of Count I.

By contrast, Count I identified no specific conduct by Andrews, Eaton, or Howe outside functions intimately associated with the judicial process. Their dismissal on absolute-immunity grounds was affirmed.

The distinction does not mean that signing or filing every charging document defeats immunity. The material allegation here was personal factual attestation under penalty of perjury in the role of a complaining witness. Nor did the court resolve any separate defense, including qualified immunity.

E. Supervisory and municipal liability required independent factual support

Howe’s supervisory position did not make him automatically responsible for the conduct of assistant prosecutors. Smith needed an affirmative connection involving personal involvement, causation, and the necessary state of mind. The complaint supplied none.

The claim against the Board similarly required more than a general allegation of a “policy, practice, or custom of unconstitutional misconduct in serious felony investigations.” Smith alleged no supporting facts showing the relevant policy or custom. The survival of a claim against individual prosecutors did not cure that separate pleading defect.

F. The surviving claim did not seek habeas relief

The district court correctly recognized that challenges to the calculation of a state sentence generally belong in habeas proceedings. But that principle did not dispose of Count I: the operative malicious-prosecution claim sought damages and did not challenge the sentence Smith was currently serving.

The court therefore rejected a requirement that Smith first present this particular claim in federal habeas proceedings. This was not a general elimination of the boundary between habeas corpus and § 1983; it was an application of that boundary to the relief and injury actually alleged.

5. Analysis: Precedents Cited and Their Influence

A. Criminal-case background

State v. Smith, No. 121,332, 2021 WL 4501835 (Kan. Ct. App. Oct. 1, 2021)

This decision supplied the original charges, verdicts, and direct-appeal result. Its reversal of the voluntary-manslaughter conviction, while affirming the other convictions, created the divided procedural posture essential to the federal court’s charge-specific analysis.

State v. Smith, 556 P.3d 926 (Kan. Ct. App. 2024)

This later decision documented the State’s decision not to retry the reversed charge, its dismissal with prejudice, and the affirmance of Smith’s resentencing. It explained both why the murder-related prosecution had ended and why Smith remained imprisoned on other convictions.

B. Screening and pleading standards

Requena v. Roberts, 893 F.3d 1195 (10th Cir. 2018)

The court relied on this case for de novo review, the application of Rule 12(b)(6)-type standards to § 1915A screening, and acceptance of well-pleaded allegations as true. It supplied the central procedural framework.

Kay v. Bemis, 500 F.3d 1214 (10th Cir. 2007), and Curley v. Perry, 246 F.3d 1278 (10th Cir. 2001)

These cases were cited as supporting authority for the relationship between screening dismissals and ordinary failure-to-state-a-claim analysis. They reinforced the governing procedural standard rather than determining the malicious-prosecution or immunity issues.

Chilcoat v. San Juan Cnty., 41 F.4th 1196 (10th Cir. 2022)

This case supplied the plausibility formulation: factual content must support a reasonable inference that the defendants are liable. That requirement explains why bare assertions of supervisory responsibility or municipal policy were insufficient.

C. Supervisory and municipal responsibility

Perry v. Durborow, 892 F.3d 1116 (10th Cir. 2018)

This precedent requires an affirmative link between a supervisor and the constitutional violation, encompassing personal involvement, causation, and the necessary state of mind. It supported dismissal of the supervisory claim against Howe.

Monell v. Dep't of Soc. Servs. of City of New York, 436 U.S. 658 (1978)

This foundational authority identifies the municipal-liability theory Smith invoked. A local governmental entity is not automatically liable for an employee’s unconstitutional act; the violation must be attributable to the entity’s own policy or custom.

Jiron v. City of Lakewood, 392 F.3d 410 (10th Cir. 2004)

The court used this case to state two requirements: a municipal employee’s constitutional violation and a municipal policy or custom that was its moving force. Smith’s unsupported policy allegation failed the latter requirement.

D. Outstanding convictions and malicious prosecution

Heck v. Humphrey, 512 U.S. 477 (1994)

This decision supplied the principal restriction on damages claims that would undermine outstanding convictions or sentences. It justified dismissal of Smith’s trial-wide claims but did not foreclose the separately targeted prosecution whose resulting conviction had been reversed and whose charge was later dismissed.

Margheim v. Buljko, 855 F.3d 1077 (10th Cir. 2017)

The court cited this case for the requirement that the criminal action terminate in the plaintiff’s favor. It identified the relevant malicious-prosecution element without making the survival of unrelated convictions dispositive.

Chiaverini v. City of Napoleon, 602 U.S. 556 (2024)

This was the decisive authority against the district court’s categorical treatment of multiple charges. It holds that valid charges do not automatically bar a Fourth Amendment malicious-prosecution claim concerning another charge lacking probable cause.

Although discussed under the opinion’s favorable-termination heading, the quoted holding concerns the effect of valid accompanying charges. Its role here was to reject an automatic bar, not to establish that Smith had proved every element of his claim or the damages attributable to the challenged charge.

E. Prosecutorial immunity

Mink v. Suthers, 482 F.3d 1244 (10th Cir. 2007)

This case established the consequence of absolute immunity: when applicable, it completely bars a § 1983 damages suit concerning the protected conduct.

Benavidez v. Howard, 931 F.3d 1225 (10th Cir. 2019)

The court relied on its functional approach, which examines the nature of the act rather than the actor’s position, the resulting harm, or whether the conduct was lawful.

Buckley v. Fitzsimmons, 509 U.S. 259 (1993)

Quoted through Benavidez v. Howard, this Supreme Court authority supplied the underlying function-based framework. It explains why a prosecutor’s title does not confer absolute protection for every act performed.

Van de Kamp v. Goldstein, 555 U.S. 335 (2009)

The opinion drew from this case the distinction between protected prosecutorial preparation or courtroom presentation and unprotected service as a complaining witness supporting a warrant application.

Roberts v. Kling, 144 F.3d 710 (10th Cir. 1998)

This was the closest factual analogy. It denied absolute immunity where a prosecutor executed a criminal complaint affirming the truth of its factual assertions. It directly supported allowing Smith’s allegations against Hill and Ronnebaum to proceed beyond screening.

6. Potential Impact

Although nonprecedential, the decision offers a useful framework for mixed-outcome criminal cases. Courts should distinguish claims attacking an entire trial from claims directed at an individually terminated charge. Neither surviving convictions nor the prosecutor’s professional title provides a universal answer.

For plaintiffs, the opinion emphasizes factual precision: identify the challenged charge, explain its termination, distinguish it from surviving convictions, and specify each defendant’s conduct. General allegations of institutional wrongdoing remain insufficient.

For prosecutors and governmental defendants, the decision underscores the importance of separating advocacy from personal factual attestation. It also preserves substantial defenses: protected advocacy remains absolutely immune, trial-wide attacks remain subject to Heck, and supervisory or municipal liability requires its own factual foundation.

On remand, Smith still faces unresolved questions concerning probable cause, the remaining elements of his claim, causation, recoverable damages, and any applicable defenses. In particular, the existence of valid convictions may remain relevant to whether the challenged prosecution caused additional injury, even though it creates no categorical bar.

7. Complex Concepts Simplified

Section 1983

A federal mechanism for suing state or local actors for violations of federal rights. It does not make every error in a criminal prosecution compensable.

Favorable termination

A requirement that the criminal proceeding underlying a malicious-prosecution claim ended favorably to the claimant. Here, the relevant conviction was reversed and the charge was later dismissed with prejudice.

Dismissal with prejudice

A final dismissal preventing the dismissed charge from being brought again.

The Heck bar

A restriction preventing damages litigation from becoming an indirect means of invalidating a still-valid criminal conviction or sentence.

Absolute prosecutorial immunity

Complete protection from damages liability for certain prosecutorial functions, even if misconduct is alleged. It depends on the activity performed.

Complaining witness

A person who personally attests to facts supporting criminal proceedings. A prosecutor performing that role does not receive absolute prosecutorial immunity merely because of the prosecutor’s office.

Respondeat superior and Monell liability

Respondeat superior means liability based simply on an employment or supervisory relationship. Section 1983 instead requires an individual supervisor’s own connection to the violation or, for a municipality, a causative policy or custom.

De novo review and remand

De novo review means independent appellate reconsideration of the legal ruling. Remand returns the surviving claim to the district court; it is not a judgment establishing liability.

8. Conclusion

The decision preserves a narrow malicious-prosecution claim while affirming the dismissal of all other claims. Its central lesson is that courts must examine the particular charge challenged and the particular function performed.

Smith’s surviving convictions did not automatically defeat a claim concerning the separately terminated murder prosecution. Likewise, Hill and Ronnebaum could not obtain absolute prosecutorial immunity at screening for alleged acts as complaining witnesses. Those conclusions permit further litigation—not a finding of wrongdoing—and give the order persuasive significance in charge-specific civil-rights cases.
