Speculation Cannot Defeat Qualified Immunity in a § 1983 Search-Warrant Falsehood Claim, and Fourth Amendment Search Rights Are Personal to the Searched Premises

Case: Darell Chancellor v. Stephen Geelhood (6th Cir. Feb. 25, 2026)  |  Court: United States Court of Appeals for the Sixth Circuit  |  Disposition: Affirmed summary judgment for the officer

1. Introduction

This appeal arose from a long-running Detroit narcotics investigation that culminated in Darell Deon Chancellor’s conviction for possession of over 450 grams of cocaine, his more than seven years of incarceration, and the later vacatur of that conviction through a stipulated state-court order prompted by a Conviction Integrity Unit (CIU) review.

Parties. Plaintiff-Appellant Darell Deon Chancellor sued Defendant-Appellee Officer Stephen Geelhood (and originally the City of Detroit, though the City claim was dismissed on bankruptcy-related procedural grounds and was not part of the appeal).

Core issues on appeal. Chancellor alleged that Geelhood (i) falsified a search-warrant affidavit, leading to Fourth Amendment violations (false arrest/false imprisonment/malicious prosecution), and (ii) suppressed exculpatory information in violation of due process duties derived from Brady v. Maryland. Chancellor also appealed dismissal of Michigan tort claims (false arrest, false imprisonment, malicious prosecution, and “gross negligence”).

2. Summary of the Opinion

The Sixth Circuit (Larsen, J.) affirmed. It held that Chancellor failed to create a genuine issue of material fact that Geelhood deliberately or recklessly made materially false statements in the search-warrant affidavit—an essential prerequisite to overcoming qualified immunity under the circuit’s framework for § 1983 “warrant falsehood” claims. The court also rejected the Brady-based due process theory because Chancellor did not identify suppressed, material favorable evidence attributable to Geelhood.

On the state-law side, the panel held that Michigan does not recognize “gross negligence” as a standalone cause of action absent an identified duty, and in any event a gross-negligence theory cannot be “fully premised” on intentional tort allegations. Chancellor’s other Michigan claims failed for essentially the same reasons his probable-cause-centered federal claims failed, given the manner in which he litigated the case.

3. Analysis

A. Precedents Cited

1) Summary judgment and appellate posture

• Butler v. City of Detroit, 936 F.3d 410 (6th Cir. 2019): supplied the de novo standard and, more importantly, the circuit’s practical guidance for evaluating § 1983 warrant-affidavit misrepresentation claims at summary judgment.
• Anderson v. Liberty Lobby, Inc., 477 U.S. 242 (1986): reinforced that the record is viewed in the light most favorable to the nonmovant.
• Moore v. Philip Morris Cos., Inc., 8 F.3d 335 (6th Cir. 1993): emphasized that “metaphysical doubt” does not suffice; the nonmovant must produce “significant probative evidence.”

2) Qualified immunity and “warrant falsehood” doctrine

• Kisela v. Hughes, 584 U.S. 100 (2018) (per curiam): restated the qualified-immunity baseline—no liability absent violation of clearly established law.
• Tlapanco v. Elges, 969 F.3d 638 (6th Cir. 2020): reiterated that a facially valid warrant is generally a complete defense, subject to an exception for deliberate/reckless material falsehoods, and it collected elements of false arrest and malicious prosecution claims (including the “lack of probable cause” requirement).
• Vakilian v. Shaw, 335 F.3d 509 (6th Cir. 2003): provided the two-part test the court applied: (1) substantial showing of deliberate falsehood or reckless disregard for the truth, and (2) materiality to probable cause.
• Butler v. City of Detroit, 936 F.3d 410 (6th Cir. 2019): was the opinion’s workhorse for the mental-state inquiry; contradiction alone often proves only possible mistake, not deliberate or reckless lying, absent evidence showing “no reasonable officer” would have sworn the affidavit.

3) Probable cause principles and informant corroboration

• District of Columbia v. Wesby, 583 U.S. 48 (2018): “probable cause is not a high bar.”
• Florida v. Harris, 568 U.S. 237 (2013): probable cause requires only a “fair probability,” less than preponderance.
• United States v. Santiago, 139 F.4th 570 (6th Cir. 2025): reiterated probable cause is less than preponderance.
• United States v. Jones, 159 F.3d 969 (6th Cir. 1998): confidential informant tip plus independent surveillance can support probable cause.
• United States v. Helton, 35 F.4th 511 (6th Cir. 2022): explained that informant reliability can be established through judicial assessment or corroboration; the informant need not be named in the affidavit.
• United States v. May, 399 F.3d 817 (6th Cir. 2005): discussed the reliability benefits of disclosure to the magistrate, but rejected a presumption of invalidity where an informant is not identified to the issuing judge; emphasized supporting facts like prior assistance in unrelated drug cases.
• United States v. Tuttle, 200 F.3d 892 (6th Cir. 2000): “independent corroboration” bolsters an informant’s tip.

4) The panel’s standing/personal-rights “puzzlement” (dicta with signposting effect)

• Claybrook v. Birchwell, 199 F.3d 350 (6th Cir. 2000): § 1983 claims are “entirely personal” to the direct victim.
• United States v. Russell, 26 F.4th 371 (6th Cir. 2022): Fourth Amendment protections are personal rights.
• Rakas v. Illinois, 439 U.S. 128 (1978): no Fourth Amendment infringement where one is aggrieved only by evidence seized from a third party’s premises.
• United States v. Salvucci, 448 U.S. 83 (1980): possession of seized goods alone does not establish Fourth Amendment “standing.”

5) Limits on “fruit of the poisonous tree” damages theories in § 1983

• Townes v. City of New York, 176 F.3d 138 (2d Cir. 1999); Hector v. Watt, 235 F.3d 154 (3d Cir. 2000), as amended (Jan. 26, 2001); Martin v. Marinez, 934 F.3d 594 (7th Cir. 2019): cited for the proposition that the exclusionary rule’s “fruit of the poisonous tree” logic does not translate into a § 1983 damages expansion for post-search prosecution and incarceration injuries.
• Codrington v. Dolak, 142 F.4th 884 (6th Cir. 2025): noted Sixth Circuit agreement that the fruit-of-the-poisonous-tree doctrine does not apply in § 1983 cases.
• Carey v. Piphus, 435 U.S. 247 (1978): damages should be tied to the “interests protected by” the constitutional guarantee.
• Heck v. Humphrey, 512 U.S. 477 (1994): common-law analogs are a “starting point” for § 1983 analysis (invoked via Hector v. Watt).

6) Arrest warrant, prosecution, and witness immunity references

• Voyticky v. Village of Timberlake, 412 F.3d 669 (6th Cir. 2005): a facially valid arrest warrant generally establishes probable cause; the presumption can yield if supporting materials are knowingly falsified.
• Sykes v. Anderson, 625 F.3d 294 (6th Cir. 2010): malicious prosecution requires lack of probable cause for the prosecution.
• Weser v. Goodson, 965 F.3d 507 (6th Cir. 2020): false imprisonment claims arising out of alleged false arrest are analyzed as false arrest.
• Moldowan v. City of Warren, 578 F.3d 351 (6th Cir. 2009): absolute immunity for trial testimony.
• Guarino v. Brookfield Twp. Trs., 980 F.2d 399 (6th Cir. 1992): declined to consider factual arguments raised for the first time on appeal.

7) Brady doctrine and police disclosure duties

• Brady v. Maryland, 373 U.S. 83 (1963): the foundational disclosure rule for favorable, material evidence.
• Est. of Andrews v. City of Cleveland, 112 F.4th 436 (6th Cir. 2024): reaffirmed Brady elements and that police share Brady obligations.
• D'Ambrosio v. Marino, 747 F.3d 378 (6th Cir. 2014): police satisfy their Brady obligation by disclosing to the prosecutor; they need not ensure disclosure to the defense.
• Hill v. Mitchell, 842 F.3d 910 (6th Cir. 2016) (opinion of McKeague, J.); Strickler v. Greene, 527 U.S. 263 (1999): stated the three Brady elements (favorable evidence, suppression, prejudice).
• United States v. Graham, 484 F.3d 413 (6th Cir. 2007): no Brady violation if the defendant knew or should have known the essential facts or could obtain them from another source.

8) Fabrication-of-evidence cross-reference

• Jackson v. City of Cleveland, 925 F.3d 793 (6th Cir. 2019); Clark v. Abdallah, 131 F.4th 432 (6th Cir. 2025): cited to note that Chancellor’s “Brady” framing more naturally resembled a fabrication-of-evidence theory, which would still fail absent evidence the evidence was knowingly fabricated.

9) Michigan governmental immunity and “gross negligence” framing

• Mays v. Governor of Mich., 954 N.W.2d 139 (Mich. 2020): governmental employee immunity and the gross-negligence exception under Mich. Comp. Laws § 691.1407(2).
• Cummins v. Robinson Township, 770 N.W.2d 421 (Mich. Ct. App. 2009) (per curiam): the statute does not create an independent “gross negligence” cause of action; plaintiff must identify a duty.
• Beaudrie v. Henderson, 631 N.W.2d 308 (Mich. 2001): reinforces the need to identify a common-law duty.
• VanVorous v. Burmeister, 687 N.W.2d 132 (Mich. Ct. App. 2004), abrogated on other grounds by Odom v. Wayne County, 760 N.W.2d 217 (Mich. 2008): gross negligence cannot be premised on intentional acts in the manner pleaded.
• Hill v. City of Detroit, 2021 WL 137381 (Mich. Ct. App. Jan. 14, 2021): barred gross-negligence claims that merely restate the “wrongful conduct” of intentional torts (false arrest/malicious prosecution).
• Peet v. City of Detroit, 502 F.3d 557 (6th Cir. 2007): declined to consider arguments first raised on appeal.
• Campbell v. Riahi, 109 F.4th 854 (6th Cir. 2024): affirmed on any basis supported by the record (used to uphold rejection of the gross-negligence claim).

B. Legal Reasoning

1) The decisive holding: failure of proof on deliberate/reckless falsehood in the search-warrant affidavit

The panel treated the case as litigated: Chancellor’s Fourth Amendment theories depended on the assertion that Geelhood lied in the search-warrant affidavit. Under Vakilian v. Shaw and Butler v. City of Detroit, Chancellor needed evidence permitting a jury to find that Geelhood made deliberate or reckless false statements (or omissions) that were material to probable cause. The court stressed Butler’s warning that contradictory testimony commonly supports competing inferences—ranging from intentional lie to negligence—and qualified immunity is not lost unless the record shows that “no reasonable officer” would have sworn the affidavit given what the officer knew.

Applying that framework, the panel concluded Chancellor’s record was too thin:

• Physical-description mismatch did not show affidavit falsity. The affidavit did not name Chancellor at all. Evidence that Chancellor was 5'11" and 245 pounds did not directly contradict an affidavit that described an unidentified man as 5'8" and 180 pounds.
• Third-party testimony did not negate surveillance or observed dealing. Alvin Thomas did not, in the panel’s view, actually testify that he observed no drug transactions; and his testimony arguably supported the possibility that an officer could have seen him on the porch (consistent with the affidavit’s “black male, ~180 lbs, ~5'8” description).
• Expert affidavit did not supply facts or methodology. The expert’s conclusory statement that surveillance was “insufficient” to establish probable cause was treated as an unsupported legal conclusion, not evidence of deliberate or reckless falsity.
• Informant documentation gaps were not enough. The absence of an informant name/records and Geelhood’s inability to remember the name could be consistent with negligence or ordinary recordkeeping practices; moreover, the affidavit contained standard indicia of reliability (prior successful uses and corroboration through surveillance), consistent with United States v. May, United States v. Helton, and United States v. Tuttle.

In short, the court held that Chancellor did not present evidence that could satisfy the “substantial showing” mental-state requirement, so qualified immunity remained intact and the Fourth Amendment claims failed.

2) The court’s “puzzlement”: personal Fourth Amendment rights and damages “bootstrapping” (not resolved, but important)

After disposing of the case as framed, the panel flagged a structural defect: under Claybrook v. Birchwell, § 1983 claims are personal to the victim, and under Rakas v. Illinois and United States v. Salvucci a person generally cannot claim a Fourth Amendment search violation based solely on a search of someone else’s premises. Because Chancellor’s consistent factual position was that he did not live at his mother’s home and was not there during the surveillance, the court questioned how he could be the direct victim of an unconstitutional search of that home.

The panel further highlighted decisions such as Townes v. City of New York, Hector v. Watt, Martin v. Marinez, and the Sixth Circuit’s own Codrington v. Dolak, which reject using the “fruit of the poisonous tree” concept to extend § 1983 damages from a search/privacy violation to the later prosecution, conviction, and sentence—because the Fourth Amendment interest is privacy, not freedom from prosecution once incriminating evidence is discovered. Even if those cases were not controlling on the precise facts, the panel underscored that liability in this domain is far from “clearly established,” reinforcing qualified immunity’s protective role.

3) What Chancellor did not litigate: falsity in the arrest-warrant materials or participation in prosecution

The panel emphasized that Chancellor did not challenge the arrest warrant materials as falsified under Voyticky v. Village of Timberlake, nor did he develop a record or argument that Geelhood “influenced or participated” in the decision to prosecute as required by Tlapanco v. Elges and Sykes v. Anderson. This mattered because the “no probable cause” element for false arrest/malicious prosecution is analytically tied to the arrest/prosecution decisions, not merely to the antecedent search.

4) Brady: no suppression of favorable, material evidence attributable to Geelhood

The court rejected Chancellor’s due process claim under Brady v. Maryland and its three-part test as stated in Hill v. Mitchell (citing Strickler v. Greene). The core theory—that Geelhood should have told prosecutors he lied in the affidavit—collapsed because the court found no triable issue that Geelhood lied in the first place.

Chancellor’s alternative Brady theory—failure to disclose that he did not match the affidavit’s physical description—failed under United States v. Graham because Chancellor already knew his own appearance and in fact used the discrepancy at trial.

In a footnote, the panel observed that the argument sounded more like fabrication of evidence (citing Jackson v. City of Cleveland and Clark v. Abdallah), but would still fail absent evidence that evidence was knowingly fabricated.

5) Michigan claims: gross negligence and governmental immunity

For “gross negligence,” the panel invoked Cummins v. Robinson Township and Beaudrie v. Henderson to reiterate that Michigan’s governmental immunity scheme does not itself create a standalone tort; a plaintiff must identify an underlying duty and then show conduct rising to statutory “gross negligence” under Mich. Comp. Laws § 691.1407(2), as discussed in Mays v. Governor of Mich..

Chancellor’s pleaded gross-negligence theory was premised on intentional falsification—fatal under Michigan authority such as VanVorous v. Burmeister and Hill v. City of Detroit. Chancellor’s attempt to pivot on appeal to a “poor investigation/no notes” negligence theory was forfeited under Peet v. City of Detroit.

On the remaining Michigan intentional tort claims, Chancellor offered no state-specific analysis and instead relied on his federal probable-cause arguments; the panel therefore disposed of them in parallel.

C. Impact

• Raises the evidentiary bar (in practice) for § 1983 “false warrant affidavit” claims. The opinion reinforces that plaintiffs must produce concrete evidence of deliberate or reckless falsity—conclusory expert opinions, missing paperwork, and generalized credibility attacks will often be treated as insufficient under the Butler/Vakilian approach.
• Signals heightened attention to “personal right” and causation boundaries. Although dicta, the “puzzlement” section invites future litigants and district courts to scrutinize whether a plaintiff can claim Fourth Amendment injury from a search of someone else’s premises, and whether an unlawful search can be repackaged into damages for conviction/incarceration without meeting the elements of arrest- and prosecution-centered torts.
• Clarifies pleading/litigation choices that can be outcome-determinative. By highlighting what was not argued (falsification in the arrest-warrant application; officer involvement in prosecution), the panel illustrates that probable cause disputes must be targeted to the particular legal process being challenged.
• Constrains Brady-based civil claims that merely re-label falsity arguments. Where the alleged “suppressed” information is either unproven (the supposed lie) or already known to the defendant (his own physical attributes), Brady theories fail under Graham.

4. Complex Concepts Simplified

• Qualified immunity. A shield for officials unless the plaintiff shows both a constitutional violation and that the violated rule was “clearly established.” Here, the court resolved the case at the “violation” stage because the record did not support deliberate/reckless falsity.
• Probable cause. A “fair probability,” not proof beyond a reasonable doubt (Florida v. Harris; District of Columbia v. Wesby). The warrant affidavit only needed enough reliable detail to justify searching the home.
• “Franks-type” warrant challenge in § 1983. While the opinion did not cite Franks by name, it applied a similar concept through Vakilian v. Shaw: the plaintiff must show deliberate or reckless falsehoods (or omissions) that were material to probable cause.
• Fourth Amendment rights are “personal.” You generally cannot sue over an illegal search of someone else’s house merely because evidence found there was used against you (Rakas v. Illinois).
• Brady obligations in civil suits. Brady concerns suppression of favorable, material evidence. If the defendant already knows the key fact (like his own height/weight), it is not “suppressed” in the Brady sense (United States v. Graham).
• Michigan “gross negligence.” It is not a free-standing tort label; it is an immunity concept that applies only after identifying an underlying duty and a recognized cause of action (Cummins v. Robinson Township), and it generally cannot be built entirely from alleged intentional misconduct (VanVorous v. Burmeister).

5. Conclusion

Chancellor v. Geelhood affirms summary judgment where a plaintiff’s § 1983 case hinges on alleged falsity in a search-warrant affidavit but the record supplies only speculation, contradictions consistent with mistake, and conclusory credibility attacks—insufficient under Vakilian v. Shaw and Butler v. City of Detroit to overcome qualified immunity. The decision also usefully flags (without deciding) two deeper constraints likely to shape future litigation: Fourth Amendment search rights are personal to the searched premises, and § 1983 damages for an unlawful search do not automatically extend to downstream prosecution and incarceration. Finally, the opinion underscores that Brady-based civil claims require actual suppression of favorable, material evidence, and that Michigan “gross negligence” theories must be tethered to an identified duty and cannot simply repackage intentional tort allegations.
