Welsh v. Lamb County: Limiting Claim-Splitting and Res Judicata for Post-Accrual §1983 Claims

Introduction

In Welsh v. Lamb County, 5th Cir. Nos. 24-10540 & 24-10576 (May 15, 2025), the Fifth Circuit consolidated two appeals brought by Lonnie Kade Welsh, a civilly committed resident at the Texas Civil Commitment Center (TCCC). Welsh alleged that staff at the facility assaulted him, that law enforcement wrongly arrested and prosecuted him on fabricated charges, and that his criminal trial was tainted by perjured testimony and malicious evidence practices. This decision addresses two parallel federal suits under 42 U.S.C. § 1983:

Welsh I: Fourth Amendment claims (false arrest, excessive force, conspiracy) against Officer Ross Hester and others.
Welsh II: Due process, equal protection, access-to-courts, and related claims against Lamb County, the City of Littlefield, Hester, and county prosecutors.

Key issues included: (1) whether Hester was entitled to qualified immunity on the false-arrest/conspiracy claims; (2) whether Welsh could amend his complaint to add due process allegations based on perjured trial testimony; (3) whether the second suit’s claims were barred as duplicative under the claim-splitting doctrine or res judicata; and (4) whether municipal defendants faced Monell liability.

Summary of the Judgment

The Fifth Circuit’s divided opinion reached these principal holdings:

Welsh I
- Affirmed summary judgment for Officer Hester on Fourth Amendment claims. The court held that (a) the magistrate’s warrant and grand jury indictment served as independent intermediaries, breaking any chain of causation for false-arrest liability, and (b) Welsh failed to raise genuine issues under Malley (unreasonable reliance on a deficient warrant) or Franks (reckless omissions or misstatements in the supporting affidavit).
- Denied Welsh’s motion to amend in Welsh I to add a due process claim based on alleged trial perjury—finding it untimely and, as to Welsh I, futile given procedural posture.
- Declined to appoint counsel for Welsh and refused to sanction Welsh based on prior litigation conduct.
Welsh II
- Granted dismissal of duplicative Fourth Amendment claims (claim splitting) and res judicata dismissal of related claims against county and city prosecutors.
- Vacated dismissal of due process, equal protection, and malicious-prosecution claims that accrued during or after Welsh’s trial, because he had no meaningful opportunity to raise them in Welsh I (Heck bar). These counts were remanded for further proceedings.
- Affirmed dismissal of municipal claims against Lamb County for failure to state a Monell claim.

Heck v. Humphrey, 512 U.S. 477 (1994): Barred § 1983 claims challenging a conviction unless the conviction was invalidated. Welsh’s initial conviction was overturned, removing the Heck bar for his § 1983 claims.
Malley v. Briggs, 475 U.S. 335 (1986): Refined qualified immunity in warrant-based arrests—requiring the plaintiff to show that an affidavit was so lacking in probable cause that reliance was unreasonable.
Franks v. Delaware, 438 U.S. 154 (1978): Allowed a Fourth Amendment challenge to a warrant on the ground that the affiant knowingly or recklessly included false statements or omitted material facts.
Deville v. Marcantel, 567 F.3d 156 (5th Cir. 2009) & McLin v. Ard, 866 F.3d 682 (5th Cir. 2017): Independent-intermediary doctrine—decisions of magistrates/grand juries break the chain of causation for false-arrest § 1983 liability unless the intermediary was tainted.
Spears v. McCotter, 766 F.2d 179 (5th Cir. 1985): Procedure for developing pro se plaintiffs’ allegations in preliminary hearings.
Monell v. New York City Dept. of Social Services, 436 U.S. 658 (1978): Municipal liability under § 1983 requires an official policy, custom, or final-policymaker act.
Restatement (Second) of Judgments §§ 24–26 (1982): Articulated the claim-splitting doctrine and recognized exceptions when a plaintiff could not feasibly raise certain claims in the first suit.

Legal Reasoning

1. Qualified Immunity & Independent Intermediary Doctrine
The court held that once Hester presented his evidence to a magistrate (for the arrest warrant) and a grand jury (for indictment), those neutral bodies functioned as independent intermediaries. Under Fifth Circuit precedent, such interposition “breaks the chain of causation” for false-arrest liability in § 1983. Welsh failed to show that Hester knowingly or recklessly misled those intermediaries under Franks or that they were so devoid of probable cause as to render reliance objectively unreasonable under Malley. Video recordings, witness statements, and contemporaneous police reports provided ample factual support.

2. Timeliness of Amendment & Heck Bar
Welsh’s effort in Welsh I to amend his complaint to add a due process theory based on perjured trial testimony was denied as untimely and futile. The court reasoned that because Welsh could not feasibly raise those allegations until after trial, but by then his Fourth Amendment suit was concluded, amendment would not advance a viable claim in Welsh I. Instead, Welsh could seek relief in Welsh II once his conviction was invalidated.

3. Claim-Splitting vs. Res Judicata
In Welsh II, the district court applied the claim-splitting doctrine (rooted in res judicata principles) to bar duplicative Fourth Amendment claims. However, for due process and malicious-prosecution claims accruing only at trial or post-conviction—claims Welsh could not raise earlier due to the Heck bar—the Fifth Circuit vacated their dismissal. The court recognized the Restatement’s exception: when “formal barriers” (here, the Heck bar) prevent a plaintiff from presenting a controversy in the first suit, a second action on those newly matured claims is not barred.

4. Municipal Liability (Monell)
Welsh did not identify a written policy, custom evidence, or a final policymaker decision by Lamb County to support municipal liability. The Fifth Circuit affirmed the dismissal of Monell claims for failure to state a claim.

Impact

Clarifies that the claim-splitting doctrine and res judicata cannot bar § 1983 claims that did not accrue or could not be raised until after an earlier suit’s procedural or legal barrier (e.g., the Heck bar) had been removed.
Reaffirms strict application of the independent-intermediary doctrine under qualified immunity for false-arrest suits, limiting judicial second-guessing of warrants and indictments absent a showing of taint or unreasonable legal error.
Provides guidance on the timeliness of post-conviction amendments in § 1983 actions and underscores the necessity of demonstrating how and why new claims could not have been filed earlier.
Highlights the Fifth Circuit’s reluctance to appoint counsel or impose sanctions absent exceptional circumstances and clear legal meritlessness.

Complex Concepts Simplified

Qualified Immunity – A legal shield for government officials unless the plaintiff shows a violation of a clearly established constitutional right.
Independent Intermediary Doctrine – Neutral decisions by magistrates or grand juries insulate officers from § 1983 false-arrest claims, unless the intermediary was “tainted” by misconduct.
Malley & Franks Claims – Challenges to warrants: Malley focuses on whether reliance on a weak affidavit was objectively unreasonable; Franks allows plaintiffs to demand suppression of an affidavit procured by knowing or reckless falsehoods or omissions.
Heck Bar – Prevents § 1983 suits that would imply the invalidity of a conviction until that conviction is reversed or invalidated.
Claim-Splitting Doctrine – Bars multiple lawsuits on the same transaction unless legal or procedural barriers prevented all claims from being raised in the first suit.
Monell Liability – Municipalities cannot be sued under § 1983 solely because they employ a wrongdoer; plaintiffs must show a municipal policy or custom caused the violation.

Conclusion

Welsh v. Lamb County refines the interplay among qualified immunity, the independent-intermediary doctrine, and preclusion doctrines in successive § 1983 actions. It confirms that once a conviction is overturned, plaintiffs may pursue new constitutional claims that could not have been raised earlier—particularly due process challenges tied to trial conduct—without running afoul of claim-splitting or res judicata. Boroughs and municipalities must still face the stringent Monell requirements. This decision will guide lower courts in handling multi-stage civil rights litigation, ensuring both the protection of officials from meritless suits and the preservation of plaintiffs’ rights to remedies for post-conviction deprivations of constitutional guarantees.
