B. Legal Reasoning
1. An independently appealable order triggers the necessary jurisdictional inquiry
The statutory starting point was straightforward. Section 1292(a)(1) permits an interlocutory appeal from an order denying an injunction. Florida’s appeal from the temporary-injunction denial therefore properly brought the case before the Eleventh Circuit.
The accompanying remand denial presented a different problem. It was not a final judgment under § 1291, and the statutory treatment of appeals from orders granting remand in federal-officer cases did not directly authorize an appeal from a refusal to remand.
The court nevertheless concluded that it had to examine that refusal. Reviewing an injunction ruling without first checking the district court’s jurisdiction could perpetuate an exercise of authority that Congress had never granted. The obligation follows from the nature of subject-matter jurisdiction, not from discretionary authority to review related questions.
The holding is expressly framed for cases removed under the federal-officer statute when the remand denial is appealed together with another appealable order. It does not make a standalone denial of remand immediately appealable.
2. “Acting under” demands more than serving a federal customer
For a private defendant, federal-officer removal requires more than showing that its work advances a federal agency’s objectives. Otherwise, an enormous range of ordinary government vendors could claim a federal forum whenever state litigation affected their businesses.
The court organized the precedents around two recurring features:
- Governmental control: a degree of direction over the contractor’s work exceeding the individualized service ordinarily provided to commercial customers.
- Governmental responsibility: a delegation of authority or assignment of a task that the government otherwise would have to undertake.
These are fact-sensitive guideposts for applying “acting under,” not a replacement for the established three-part removal framework. Formal delegation is a strong route to qualification, but the opinion also recognizes arrangements in which a contractor performs a basic governmental task without a formal delegation of legal authority.
3. Advertising customization did not establish exceptional federal control
Snap identified substantial collaboration: agency briefs, research, messaging specifications, interactive advertisements, dedicated client support, feedback, and final approval. The court nevertheless regarded these as ordinary features of an advertising transaction.
Its coffee-shop analogy captures the distinction. A customer may specify a complicated beverage, review the result, and approve it without becoming a superior under whose authority the barista acts. Likewise, agency control over the message being purchased does not necessarily create a federal supervisory relationship over the seller.
The decisive point was not that Snap’s work lacked value or customization. It was that the agencies purchased advertising services in substantially the same manner as other advertisers. Describing Snap as a “foundational collaborator,” or emphasizing its ability to reach teenagers, did not change that commercial structure.
4. The agencies retained their responsibilities rather than delegating them
DHS and the FDA unquestionably possessed statutory authority to conduct public-information campaigns. But the existence of agency authority did not establish that Snap received any of it.
The agencies continued to direct their outreach efforts and used Snap’s products to distribute their messages. The agreements did not appoint Snap to exercise federal authority or assign it an equivalent governmental role. The court therefore distinguished using a private service to carry out an agency’s mission from placing the service provider in a delegated governmental position.
The absence of delegation was particularly significant because Snap’s relationships also lacked the other features that had supported removal in the contractor precedents. Neither memoranda of understanding nor a contract, by their labels alone, established the necessary relationship.
5. The remaining federal-officer requirements were left undecided
Once Snap failed to establish that it acted under a federal officer, the court did not need to decide whether Florida’s claims sufficiently related to its federal work or whether Snap had a colorable federal defense. The opinion thus does not adjudicate the strength of Snap’s constitutional or preemption defenses, even under the relatively preliminary “colorable” standard.
6. Florida’s sovereign enforcement interest defeated diversity jurisdiction
Snap’s alternative theory depended on treating Florida as a nominal plaintiff and individual minors as the true interested parties. The court rejected that characterization by examining the claims and requested relief.
The statutes did not require the Department to allege specific injuries to particular children, and its complaint made no such allegations. Civil penalties followed statutory violations, and the Department sought those penalties for itself rather than as compensation payable to injured individuals.
Accordingly, the State’s own enforcement interest was real and direct. The fact that legislation protects identifiable people does not mean those people become the sole real parties in every governmental enforcement action.
No additional district-court fact-finding was necessary: the existing record established Florida’s role. Because Florida is not a citizen under § 1332, its genuine participation foreclosed diversity jurisdiction.
7. Jurisdiction had to precede constitutional adjudication
The panel acknowledged that HB3 raised serious constitutional questions but lacked authority to decide them in this improperly removed case. This was not simply a discretionary preference for a narrower ruling. Without subject-matter jurisdiction, the federal district court could not resolve Florida’s injunction request on the merits.
The remedy followed that limitation. Vacating the injunction denial did not grant Florida an injunction; it removed a ruling entered in a case that did not belong in federal court.
C. Potential Impact
Appellate practice
The opinion supplies persuasive guidance that, in the specified federal-officer removal setting, parties cannot assume that the appellate court will reach an injunction’s substantive merits before examining removal. The jurisdictional inquiry is mandatory even though the remand denial would not independently support an immediate appeal.
Government contractors and digital platforms
The reasoning limits attempts to convert ordinary federal purchasing relationships into federal-officer status. Advertising platforms, technology vendors, and other service providers should expect scrutiny of operational control and governmental responsibility, not merely evidence of agency collaboration, customized deliverables, or federal approval.
The opinion does not categorically exclude advertisers or technology companies from § 1442. A materially different arrangement involving delegated duties or unusually close federal direction could produce a different result. Its central lesson is that a federal customer is not necessarily a federal superior.
State regulatory enforcement
The diversity analysis strengthens the distinction between sovereign enforcement and litigation conducted merely as a representative for private claimants. Where a State seeks its own statutory penalties without needing to prove individualized injury, defendants cannot establish diversity simply by identifying the residents whom the law protects.
That conclusion remains claim- and remedy-sensitive. The opinion does not hold that every action brought in a State’s name necessarily defeats diversity; it holds that Florida was genuinely interested in this enforcement action.
Social-media regulation and constitutional litigation
The immediate effect is procedural: this enforcement action returns to state court. The opinion neither endorses Florida’s social-media policy nor rejects Snap’s objections to it. It leaves the substantive constitutional controversy, including the separate litigation over HB3, unresolved.
