Catanese v. Curtis — Conclusory Fourth Amendment Claims, Waiver, and Qualified Immunity in Emergency-Aid “Sober Home” Entries

1. Introduction

Catanese v. Curtis (1st Cir. Aug. 21, 2026) arose from three warrantless police entries into a Massachusetts “sober home,” Genesis House, in response to (i) an overdose call (Oct. 2019), (ii) execution of an arrest warrant and later follow-up searches for a fugitive (Dec. 2019), and (iii) a second overdose call (Jan. 2020). Plaintiffs—former residents and the homeowner/operator—alleged unconstitutional searches and seizures under the Fourth Amendment and parallel Massachusetts theories, plus a raft of state-law torts and a civil conspiracy claim.

The central issues on appeal were narrow because plaintiffs conceded the legality of key initial entries/searches: Officer Curtis’s initial Oct. 2019 entry/search; the police’s initial Dec. 2019 entry/search for a fugitive pursuant to an arrest warrant; and Officer Martin’s initial Jan. 2020 entry/search. What remained were claims that officers (a) searched or detained beyond the permissible scope of consent/emergency aid, (b) participated in unconstitutional conduct without individualized proof tying each named officer to the alleged acts, and (c) conspired under Massachusetts law.

2. Summary of the Opinion

The First Circuit affirmed summary judgment for the officers. It held that:

  • Several Fourth Amendment theories failed because plaintiffs offered only conclusory assertions about “continued” searches and “interrogations,” without specific record facts (scope, duration, places searched, or concrete coercive conduct) sufficient to reach a jury.
  • Other claims were waived due to undeveloped argumentation (including arguments made perfunctorily or in footnotes without supporting authority) and because plaintiffs failed to address district-court reasoning.
  • Remaining January 2020 claims were barred by qualified immunity: the record did not show Carpenter conducted a second search; his entry was objectively reasonable under emergency aid given the timeline; and plaintiffs did not identify clearly established law making his arrival/entry unlawful merely because he arrived after another officer.
  • The Massachusetts civil conspiracy claim failed because plaintiffs could not establish an underlying tort once the tort claims were dismissed/waived.

3. Analysis

A. Precedents Cited

1) Summary judgment, record proof, and appellate waiver

  • Boudreau v. Lussier supplied the posture rule: on appeal from summary judgment, the court views facts in the light most favorable to the nonmovant, but only where supported by competent record evidence.
  • John B. Cruz Constr. Co. v. Beacon Cmtys. Corp. and Johnson v. Johnson anchored the requirement that a party resisting summary judgment must identify specific facts, not speculation, and must show a genuine dispute that could change the outcome.
  • Est. of Bennett v. Wainwright and Tower v. Leslie-Brown were used to reject Fourth Amendment claims where the evidentiary proffer was thin, conclusory, or amounted to a “mere scintilla,” especially regarding the scope of alleged searches.
  • Wilson v. Bradlees of New Eng., Inc. reinforced that appellate courts are not required to “scour the record” to find support for a party’s position; the burden remains on the appellant to cite the evidence.
  • United States v. Zannino was repeatedly deployed to deem arguments waived when presented perfunctorily, without developed reasoning or supporting authority—an especially consequential feature of this decision.
  • Best Auto Repair Shop, Inc. v. Universal Ins. Grp. and Díaz-Colón v. Fuentes-Agostini supported the court’s refusal to disturb rulings where appellants failed to grapple with the district court’s analysis and relied on conclusory assertions.
  • J.S.H. v. Newton confirmed that the First Circuit may affirm on any ground apparent from the record—important given the mix of merits, waiver, and immunity rationales.

2) Core Fourth Amendment doctrines: home, warrant exceptions, scope limits, and seizures

  • Mincey v. Arizona and Katz v. United States provided the canonical framework: warrantless home entries/searches are presumptively unreasonable, subject to “well-delineated exceptions.”
  • United States v. Giambro framed the home’s special status and summarized the emergency aid exception as requiring an objectively reasonable basis to believe someone inside needs immediate aid.
  • United States v. Rodríguez-Pacheco and United States v. Coombs supplied the consent exception and emphasized that valid consent can justify entry and search within the consent’s scope.
  • United States v. Gamache and United States v. Marshall were cited to constrain consent searches: consent to enter does not authorize “carte blanche” rummaging; the scope is measured by objective reasonableness and the expressed object/purpose of the search.
  • Case v. Montana (2026) was central to the emergency-aid “scope” limit: an emergency-aid entry “provides no basis to search the premises beyond what is reasonably needed” to handle the emergency and officer safety, and the emergency determination looks to the totality known at the time.
  • Florida v. Bostick defined seizure through the “free to decline/terminate” standard.
  • Missouri v. McNeely reinforced totality-of-circumstances analysis for reasonableness.
  • Payton v. New York, United States v. Weidul, and Brigham City v. Stuart set the baseline: warrantless home entry to seize generally requires a warrant, but consent and emergency aid are exceptions.
  • Kentucky v. King and Graham v. Connor reinforced that Fourth Amendment reasonableness is objective; subjective motivations (e.g., alleged “vendetta”) do not control the constitutional analysis.
  • Miranda v. Arizona and Padson v. City of Peabody were invoked to reject the plaintiffs’ undeveloped “right to remain silent” framing, emphasizing Miranda’s custody predicate.
  • Plumhoff v. Rickard was used to dispose of attempts to base plaintiffs’ Fourth Amendment rights on another person’s alleged seizure (Fourth Amendment rights are personal and cannot be vicariously asserted).

3) Individual liability and attribution of unconstitutional acts

  • Ocasio-Hernández v. Fortuño-Burset and Rodríguez-García v. Miranda-Marín were used to emphasize that a defendant officer is liable only for his or her own acts/omissions (or condonation/tacit authorization), not for unidentified officers’ conduct.
  • Rivera-Corraliza v. Puig-Morales supported rejecting claims resting on allegations in briefing rather than competent evidence tying defendants to the acts.
  • Besosa-Noceda v. Torres reinforced that unsupported conjecture cannot defeat summary judgment.

4) Qualified immunity

  • Hill v. Walsh and District of Columbia v. Wesby provided the two-prong immunity test: (1) constitutional violation, and (2) clearly established law placing unlawfulness beyond debate in the specific context.

5) Massachusetts constitutional gloss and civil conspiracy

  • Commonwealth v. Alexis, Commonwealth v. Evelyn, Commonwealth v. Lyles, Commonwealth v. Buckley, and Commonwealth v. Arias were cited to acknowledge that Article 14 can be more protective than the Fourth Amendment, while still relying on objective reasonableness and recognizing consent/emergency-aid doctrines. The First Circuit treated the state and federal standards as coextensive here because plaintiffs failed to develop any material divergence argument.
  • Pheasant Ridge Assocs. Ltd. P'ship v. Burlington appeared in plaintiffs’ bad-faith theory, but the court rejected it as irrelevant to Fourth Amendment objectivity, consistent with Graham v. Connor.
  • Thomas v. Harrington provided the taxonomy of Massachusetts civil conspiracy (concerted action vs. power of coercion).
  • Kurker v. Hill, Taylor v. Am. Chemistry Council, and Kyte v. Philip Morris Inc. supplied the concerted-action elements (agreement/assistance + underlying tort).
  • Finamore v. Miglionico was the decisive citation: without an underlying tort, there is no actionable civil conspiracy.

B. Legal Reasoning

1) The opinion’s practical “gatekeeping” themes

Although the facts involved repeated police contact with a sober home and allegations of retaliatory animus, the court’s reasoning is largely structural and procedural: Fourth Amendment claims at summary judgment live or die on (i) specific, attributable facts and (ii) developed legal argument. The panel repeatedly declined to infer constitutional violations from generalized descriptions like “continued to search,” “interrogated,” or “detained,” especially where plaintiffs could not identify where officers searched, what was searched, for how long, or which named officer performed the act.

2) October 2019: “continued search” and questioning

Plaintiffs conceded the initial overdose-response entry/search was lawful. Their remaining theory was that Officer Curtis searched and detained/interrogated residents after the emergency ended. The First Circuit found the record deficient: statements that police “began to search the house again” and were present “more than an hour” lacked details about the scope, duration, and locations of any additional search, and therefore could not show unreasonableness under emergency-aid limits (Case v. Montana).

For seizure, plaintiffs did not meaningfully show that questioning after a confirmed overdose was objectively unreasonable. They recalled only a question such as “who owned the house” and offered no authority why such inquiry, in context of an overdose at a sober home, would violate the Fourth Amendment. The court underscored the primacy of objective reasonableness (Kentucky v. King) and treated subjective “vendetta” allegations as legally irrelevant (Graham v. Connor).

3) December 2019: attribution failures and waiver

Plaintiffs conceded the initial entry to execute an arrest warrant and search for Andrade was valid. Their remaining arguments collapsed for two reasons:

  • Attribution/individual liability: claims rested on acts attributed to “a State Trooper” or “another police officer,” not to Detectives Bartolomei or Carpenter. Under Ocasio-Hernández v. Fortuño-Burset, liability requires proof the named defendant did (or condoned/authorized) the unconstitutional act.
  • Waiver/undeveloped argument: the challenge to reliance on Newcomb’s tip was raised perfunctorily in a footnote without supporting law, triggering waiver under United States v. Zannino.

The court also rejected an attempt to reframe questioning as unconstitutional interrogation requiring Miranda warnings: without a developed showing of custody, Miranda does not apply (Padson v. City of Peabody), and plaintiffs did not satisfy the seizure standard under Florida v. Bostick.

4) January 2020: qualified immunity and the “second officer arrives” scenario

With respect to Detective Carpenter, the panel affirmed qualified immunity on a record-driven and “clearly established law” analysis. The timeline showed Carpenter arrived shortly before the overdose victim was transported, making it objectively reasonable for him to believe emergency aid was still ongoing (United States v. Giambro). Importantly, the district court’s reconsideration ruling (referenced by the panel) also held plaintiffs cited no controlling precedent “clearly establishing” that an exigent/consent-based entry becomes unlawful simply because a second officer arrives shortly after the first or because brief time passes—failing prong two under Hill v. Walsh and District of Columbia v. Wesby.

On the alleged search, the court found “no evidence” Carpenter conducted a second search; plaintiffs’ briefing pointed to a later MSP search instead. And on seizure, questions about what drugs were ingested and their source were treated as objectively consistent with an overdose investigation; subjective motives were deemed irrelevant (Brigham City v. Stuart).

5) State claims and conspiracy

The court deemed most state-law tort challenges waived due to lack of meaningful appellate development (United States v. Zannino). That waiver had a knock-on effect: under Massachusetts “concerted action” conspiracy doctrine (Thomas v. Harrington; Kyte v. Philip Morris Inc.), conspiracy liability requires an underlying tort. With those torts dismissed and not properly challenged, conspiracy necessarily failed (Finamore v. Miglionico).

C. Impact

The decision’s likely influence is less about expanding substantive Fourth Amendment doctrine and more about reinforcing litigation discipline in police-entry cases:

  • Emergency-aid litigation will remain fact-specific and record-dependent: plaintiffs must identify concrete facts about where officers searched, for how long, and how the search exceeded emergency needs; generalized “they kept searching” narratives are unlikely to survive summary judgment.
  • “Second responder” immunity protection: absent clearly established precedent to the contrary, an officer who arrives shortly after an initial emergency-aid entry may be insulated by qualified immunity when the emergency plausibly continues.
  • Individualized attribution is essential: plaintiffs must connect each named defendant to the alleged unconstitutional act; referencing “other officers” or different agencies will not suffice.
  • Appellate waiver is outcome-determinative: perfunctory or footnoted arguments can forfeit potentially substantive issues, including state constitutional divergences and informant-reliability challenges.
  • Massachusetts conspiracy claims remain parasitic: without a viable underlying tort, “concerted action” conspiracy cannot proceed.

4. Complex Concepts Simplified

  • Emergency aid exception: Police may enter a home without a warrant when, viewed objectively, they reasonably believe someone inside needs immediate help. The search must be limited to what is reasonably necessary to address the emergency and officer safety.
  • Scope limits (consent/emergency): Even when entry is lawful, officers cannot automatically search everywhere; courts ask whether what the officer did matched the lawful purpose (e.g., treating an overdose, locating a person, ensuring safety).
  • What counts as a “seizure”: A person is seized if a reasonable person would not feel free to end the encounter or refuse police requests.
  • Qualified immunity: Even if a constitutional violation is alleged, officers are immune unless the illegality was “clearly established” by existing precedent in a sufficiently similar context.
  • Waiver on appeal: Courts will not build arguments for parties; issues must be argued with supporting authority and engagement with the lower court’s reasoning.
  • Massachusetts civil conspiracy (concerted action): It is not a standalone wrong; it attaches liability for an underlying tort committed by someone else when defendants agreed to or substantially assisted that tort.

5. Conclusion

Catanese v. Curtis affirms that Fourth Amendment challenges to emergency responses and warrant-related entries—especially in communal or regulated living environments like sober homes—require precise, attributable, record-supported facts showing that officers exceeded the lawful scope of consent or emergency aid. The opinion also underscores how waiver and qualified immunity can be dispositive: undeveloped arguments are forfeited, and absent clearly established law, officers responding sequentially to an ongoing emergency are likely to be protected. Finally, the case reiterates a basic Massachusetts principle: without a surviving underlying tort, a “concerted action” civil conspiracy claim cannot stand.
