St. Maron v. City of Houston, 78 F.4th 754

Background

City of Houston had used certain vacant lots as a dumping ground for dirt and construction debris, raising the lots ~8–10 feet and preventing absorption of stormwater.
Stormwater shed from the lots into adjacent Ella Park Terrace homes, leading residents to repeatedly complain of flooding.
The Mayor and City Council directed the City Attorney and Public Works to address the problem; the City Attorney sued Gallegos in county court in the name of the Ella Park civic association and obtained an injunction declaring the lots a public nuisance.
Relying on that injunction, Public Works entered and repeatedly modified the lots without consent, engineering studies, easements, or condemnation, allegedly damaging Plaintiffs’ properties and depriving them of use.
Plaintiffs sued under 42 U.S.C. § 1983 (Takings Clause, procedural due process, equal protection) and state tort/statutory claims; the district court dismissed state claims (sovereign immunity) and dismissed the § 1983 claims under Monell.
The Fifth Circuit affirmed dismissal of state claims but reversed the § 1983 dismissal, holding Plaintiffs plausibly alleged a Monell claim because the Mayor and City Council (final policymakers) deliberately directed and ratified the challenged actions.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Plaintiffs pled an official municipal policy under Monell that caused constitutional violations	City officials (Mayor & City Council) made a deliberate choice to pursue an injunction and direct Public Works, constituting an official policy/decision	City argued Plaintiffs failed to plead any official policy or action by final policymakers sufficient for Monell liability	Held for Plaintiffs: Allegations that Mayor and City Council directed and ratified the scheme suffice to plead an official policy (single-decision theory)
Whether the Mayor and City Council qualify as final policymakers for Monell attribution	The Houston Charter vests administrative control and policymaking authority in the Mayor and City Council, so their directives are attributable to the City	City contended that specific department actors, not the Mayor/Council, made the decisions and Plaintiffs didn’t identify final decisionmakers	Held for Plaintiffs: Charter shows Mayor/Council are final policymakers; their direction/ratification is attributable to the City
Whether Plaintiffs showed causation and requisite culpability (deliberate indifference) linking the policy to constitutional deprivations (takings/due process)	The City used the injunction to justify repeated physical invasions/modifications of property and failed to provide notice/opportunity to other owners—resulting in per se takings and due-process violations	City argued independent nuisance authority or insufficient causal link/deliberate indifference	Held for Plaintiffs: Complaint alleges City actions were the moving force and showed deliberate indifference to owners’ rights, supporting Takings and procedural-due-process claims
Whether state-law tort/statutory claims against Houston survive sovereign immunity or fit waiver exceptions (e.g., Reata)	Plaintiffs argued City acted on behalf of private citizens (proprietary function) or waived immunity by interjecting into litigation	City argued storm-sewer/related functions are governmental and immunity applies; Reata waiver is narrow and inapplicable	Held for City: Sovereign immunity bars the state claims; storm/stormwater functions are governmental under Texas law and Reata’s narrow waiver does not apply
