Appeal from the United States District Court

for the Southern District of Florida

(August 31, 2016)

Case: 15-13721 Date Filed: 08/31/2016 Page: 3 of 17

Before WILSON and JULIE CARNES, Circuit Judges, and MOORE,* District 

Judge. 

JULIE CARNES, Circuit Judge:

Plaintiffs sued various local government defendants (“Defendants”),

claiming unjust enrichment and seeking disgorgement of traffic fines Plaintiffs

allege were imposed in violation of Florida law. Defendants moved to dismiss the 

claim, asserting sovereign immunity. The district court denied Defendants’ motion 

to dismiss, and Defendants now appeal. After a careful review of the record and 

controlling Circuit precedent, and with the benefit of oral argument, we dismiss 

this interlocutory appeal for lack of jurisdiction. 

BACKGROUND

Plaintiffs filed this class action against red-light camera vendor American 

Traffic Solutions, Inc. (“ATS”), a company that contracts with Florida local 

governments to install and operate unmanned cameras designed to capture video 

images of traffic violations. Plaintiffs alleged in the complaint that they were 

filmed committing a traffic violation on one of these cameras, and that they

subsequently received a traffic citation and paid a fine. According to Plaintiffs, the 

citations were void, and the fines were thus unlawful, because the red-light camera 

programs violated Florida law in several respects.

* Honorable William T. Moore, United States District Judge for the Southern District of 

Georgia, sitting by designation. 

Case: 15-13721 Date Filed: 08/31/2016 Page: 4 of 17

Other plaintiffs subsequently filed similar actions in various state and federal 

courts in Florida, and all of the actions were consolidated with this case under the 

first-filed rule. Plaintiffs prepared an amended master complaint in the 

consolidated action, asserting claims against Defendants, the Florida Department 

of Revenue, and three red-light camera vendors, including ATS. The master 

complaint alleges that Defendants unlawfully issued citations and collected fines 

for traffic violations recorded by red-light cameras. Among other claims, it 

includes an unjust enrichment claim in which Plaintiffs seek disgorgement of the 

fines they paid to Defendants.

The fines that are the subject of the unjust enrichment claim were imposed 

pursuant to the Mark Wandall Traffic Safety Program (the “Wandall Act”), Florida 

Statutes § 316.0083. The Wandall Act authorizes the use of red-light cameras, and

it creates a detailed procedure that must be followed by a local government when 

issuing citations and imposing fines under this program. Id. Pursuant to the 

Wandall Act, a Florida appellate court recently invalidated the red-light camera 

program operated by the City of Hollywood. See City of Hollywood v. Arem, 154 

So. 3d 359, 361 (Fla. Dist. Ct. App. 2014). The court in Arem held that 

Hollywood’s program violated the Wandall Act because it unlawfully delegated 

police power to a red-light camera vendor by allowing the vendor to (1) pre-screen 

and determine which camera shots to send to Hollywood’s traffic enforcement 

Case: 15-13721 Date Filed: 08/31/2016 Page: 5 of 17 
6

officer and (2) issue traffic citations with the mere acquiescence of the 

enforcement officer. Id. The court concluded that citations issued pursuant to 

Hollywood’s red-light camera program were void and should be dismissed. Id. at 

361, 365.

In support of their unjust enrichment claim, Plaintiffs allege that Defendants 

operated similarly unlawful red-light camera programs. Specifically, Plaintiffs 

contend that Defendants violated the Wandall Act by improperly delegating prescreening authority to ATS and other red-light camera vendors. See id. at 365 

(stating that, under Florida law, a local government “lacks the lawful authority to 

outsource to a third-party vendor the ability to make the initial review of the 

computer images of purported violations”). In addition, Plaintiffs assert that the 

citations they received were unlawfully issued by red-light camera vendors rather 

than by a Florida law or traffic enforcement officer. See id.

Defendants moved to dismiss the unjust enrichment claim on the ground of 

sovereign immunity. In support of their motion, Defendants argued that the unjust 

enrichment claim was a “quasi-contract” claim barred by sovereign immunity 

under Florida law. The district court denied the motion. It construed the unjust 

enrichment claim as a claim to recover an “unlawful monetary extraction” rather 

than as a quasi-contract claim. According to the district court, Florida sovereign 

immunity does not apply to an unlawful extraction claim. 

Case: 15-13721 Date Filed: 08/31/2016 Page: 6 of 17 
7

Defendants filed an interlocutory appeal of the district court’s denial of 

sovereign immunity. Plaintiffs moved to dismiss the appeal for lack of jurisdiction

and for a frivolity determination and sanctions pursuant to Federal Rule of 

Appellate Procedure 38. The motion was carried with the case, and this Court 

heard oral argument on both the jurisdictional issue and the merits of the sovereign 

immunity claim. For the reasons that follow, we now grant Plaintiffs’ motion to

dismiss the appeal for lack of jurisdiction, but deny their request for sanctions 

under Rule 38.

DISCUSSION

I. Jurisdiction

Our jurisdiction is limited to appeals from “final decisions” of the district 

court. 28 U.S.C. § 1291. An order denying a motion to dismiss does not result in a 

final decision. Thus, we lack jurisdiction to review such an order unless it is 

“otherwise made appealable by statute or jurisprudential exception.” The Royalty

Network, Inc. v. Harris, 756 F.3d 1351, 1355 (11th Cir. 2014) (internal quotation 

marks omitted). The only exception potentially applicable here arises under the 

collateral order doctrine. See id. (citing Cohen v. Beneficial Indus. Loan Corp.,

337 U.S. 541, 69 S. Ct. 122 (1949)). That doctrine permits the immediate appeal 

of an interlocutory order if it (1) conclusively determines an important issue that is 

Case: 15-13721 Date Filed: 08/31/2016 Page: 7 of 17 
8

both (2) completely separate from the merits of the case and (3) effectively 

unreviewable on appeal from a final judgment. Id.

It is by now well-established that an order denying federal qualified 

immunity satisfies the above requirements. See Schmelz v. Monroe Cty., 954 F.2d 

1540, 1543 (11th Cir. 1992) (citing Mitchell v. Forsyth, 472 U.S. 511, 530, 105 S. 

Ct. 2806, 2817 (1985)). Such an order conclusively determines whether a 

government official is entitled to immunity from suit in his individual capacity, an 

important issue that is separate from the merits of the case. Mitchell, 472 U.S. at 

527–528, 105 S. Ct. at 2816. And as qualified immunity protects public officials 

from the burden of litigation, rather than just liability, its protection is irretrievably 

lost—in a ruling that is “effectively unreviewable on appeal from a final 

judgment”—when a claim to qualified immunity is denied in an interlocutory 

order. Id. at 525–27, 105 S. Ct. at 2814–16.

Similarly, an order denying state official or sovereign immunity is 

immediately appealable if state law defines the immunity at issue to provide 

immunity from suit rather than just a defense to liability. See Tinney v. Shores, 77

F.3d 378, 383 (11th Cir. 1996) (“Alabama intended for its state officers to be 

immune from suit. As such, the denial of summary judgment based on sovereign 

immunity is properly before us on interlocutory appeal.”); Griesel v. Hamlin, 963 

F.2d 338, 341 (11th Cir. 1992) (“Because sovereign immunity under Georgia law 

Case: 15-13721 Date Filed: 08/31/2016 Page: 8 of 17 
9

is an immunity from suit, . . . we have jurisdiction over the district court’s order 

denying summary judgment based on sovereign immunity under Georgia law.”). 

As with federal qualified immunity, the denial of state official or sovereign 

immunity conclusively resolves an important issue that is separate from the merits 

of the case. See Griesel, 963 F.2d at 340. If the state immunity is intended to 

shield a governmental entity or official from suit rather than just liability, its denial 

in an interlocutory order is also “effectively unreviewable after trial.” Id. 

This Court, however, has interpreted Florida sovereign immunity law to 

provide only a defense to liability, rather than immunity from suit. CSX Transp.,

Inc. v. Kissimmee Util. Auth., 153 F.3d 1283, 1286 (11th Cir. 1998) (per curiam).

Based on that interpretation, we held in CSX that an order denying Florida 

sovereign immunity is not immediately appealable under the collateral order 

doctrine. Id. CSX decided the jurisdictional issue presented by this case, and it is 

controlling as to that issue unless it has been “undermined to the point of 

abrogation” by an intervening change in Florida sovereign immunity law. United 

States v. Archer, 531 F.3d 1347, 1352 (11th Cir. 2008)1

; see also United States v. 

Clarke, 822 F.3d 1213, 1215 (11th Cir. 2016) (noting that a prior panel decision 

interpreting state law is binding on the Court unless it has been abrogated by an 

1 A prior panel decision also can be overruled or abrogated by a decision of the United States 

Supreme Court or this Court sitting en banc, see Archer, 531 F.3d at 1352, but Defendants 

acknowledge that there is no Supreme Court or circuit authority to suggest that CSX is no longer 

controlling. 

Case: 15-13721 Date Filed: 08/31/2016 Page: 9 of 17 
10

intervening decision of the relevant state court). Contrary to Defendants’ 

argument, there is no clear authority to suggest such a change has occurred in

Florida law.

This Court’s decision in CSX was based on the Florida Supreme Court’s 

discussion of the scope of Florida sovereign immunity in Department of Education 

v. Roe, 679 So. 2d 756 (Fla. 1996). The question presented in Roe was whether the 

Florida Department of Education was entitled to interlocutory review of an order 

denying its claim to sovereign immunity in a negligence action. Id. at 757. The 

Florida Supreme Court held that it was not, id. at 759, but its holding was less 

important than its more general discussion of the nature of Florida sovereign 

immunity for purposes of the collateral order doctrine. See CSX, 153 F.3d at 1286 

(“[J]ust because a state court, under its own jurisdictional laws and rules, does not 

have jurisdiction over a kind of interlocutory appeal, does not dictate a lack of 

jurisdiction in this court.”). 

In the course of its discussion, Roe distinguished between sovereign 

immunity asserted by a governmental entity like the Department of Education (and 

the local governments in this case) and federal qualified immunity asserted by a 

public official sued individually. Roe, 679 So. 2d at 759. Specifically, Roe noted 

that (1) “qualified immunity is rooted in the need to protect public officials from 

undue interference, whereas sovereign immunity is not” and (2) defending a suit is 

Case: 15-13721 Date Filed: 08/31/2016 Page: 10 of 17 
11

not likely to have the same “chilling effect” on a governmental entity as it would 

on a public official sued individually. Id. Based on those differences, Roe

indicated that Florida sovereign immunity, unlike federal qualified immunity, 

provides only a defense to liability rather than immunity from suit. Id. On that

point, Roe stated: “although the state will have to bear the expense of continuing 

the litigation, the benefit of immunity from liability, should the state ultimately 

prevail on the sovereign immunity issue, will not be lost simply because review 

must wait until after final judgment.” Id. That statement was central to this 

Court’s decision in CSX. CSX, 153 F.3d at 1286.

The Florida Supreme Court has not overruled Roe or expressly altered its 

definition of the scope of Florida sovereign immunity. In fact, Roe has been cited 

favorably in several recent decisions that suggest its continuing validity. See Fla. 

Fish and Wildlife Conservation Comm’n v. Jeffrey, 178 So. 3d 460, 465 (Fla. Dist. 

Ct. App. 2015) (citing Roe for the proposition that Florida sovereign immunity 

does not immunize a governmental entity from suit); Keck v. Eminisor, 104 So. 3d 

359, 365–66 (Fla. 2012) (per curiam) (distinguishing Roe in a case involving 

individual immunity under Fla. Stat. § 768.28). Keck is instructive. Keck held that

individual immunity granted to government employees under Florida Statutes §

768.28(9)(a) provides immunity from suit, and that an order denying it is thus 

subject to interlocutory review. Keck, 104 So. 3d at 366. In so holding, Keck 

Case: 15-13721 Date Filed: 08/31/2016 Page: 11 of 17 
12

relied on the plain language of § 768.28(9)(a), which states that a government 

employee cannot be “named as a defendant” in an action arising out of his 

employment unless he acted maliciously or in bad faith. Id. Thus, Keck did not 

overrule Roe, but rather distinguished it, emphasizing that Roe involved sovereign 

immunity asserted by a governmental entity, and thus it did not raise the qualified 

immunity-like considerations that underlie individual immunity and that warrant an 

immediate appeal in the event of denial of that immunity. Id. at 365–66.

Defendants argue that Roe should be interpreted narrowly, so that its 

definition of Florida sovereign immunity is only applicable to immunity from tort 

claims, which the state has partially waived by virtue of § 768.28, and not to 

immunity from other types of claims, such as the unjust enrichment claim at issue 

in this case. That argument is foreclosed by CSX, which interpreted Roe to stand 

for the broad proposition that “Florida’s state sovereign immunity is only 

immunity from liability.” CSX, 153 F.3d at 1286. Indeed, the governmental entity

in CSX sought immunity from a contractual indemnification claim rather than a tort 

claim, yet this Court readily applied Roe to conclude that the denial of immunity 

was not immediately appealable under the collateral order doctrine. Id. at 1284,

1286. Accepting Defendants’ proffered interpretation of Roe would thus require us 

to hold that CSX was wrongly decided, rather than that it has been abrogated. We 

are not authorized to make that holding. See United States v. Steele, 147 F.3d 

Case: 15-13721 Date Filed: 08/31/2016 Page: 12 of 17 
13

1316, 1317–1318 (11th Cir. 1998) (“Under our prior precedent rule, a panel cannot 

overrule a prior one’s holding even though convinced it is wrong.”).

Defendants also contend that Roe was abrogated by the Florida Supreme 

Court’s decision in Wallace v. Dean, 3 So. 3d 1035 (Fla. 2009). Their argument is 

undermined by the fact that Wallace predated Keck and Jeffrey, both of which 

reaffirmed Roe’s validity, and further weakened by the fact that Wallace did not 

discuss or even cite Roe. It is not surprising that Wallace failed to mention Roe. 

Wallace raised two issues: (1) whether a sheriff owed a duty of care to the plaintiff

pursuant to the undertaker’s doctrine and (2) assuming there was a duty, whether 

the sheriff was sovereignly immune from tort liability under a discretionary 

function analysis. Id. at 1043–44. Neither of those issues required a determination 

as to whether Florida sovereign immunity provides immunity from suit or only a 

defense to liability, or otherwise implicated Roe’s definition of the scope of 

sovereign immunity.

Because the lower court’s decision conflated the duty and immunity issues,

Wallace discussed at some length the distinction between a lack of duty—and thus 

a lack of liability—under tort law and the presence of sovereign immunity. Id. at 

1040, 1044–45. During the course of its discussion, Wallace off-handedly referred

to sovereign immunity as “immunity from suit” and as “bar[ring] an action.” Id. at 

1044–45. But we do not believe that reference was intended to signal disapproval 

Case: 15-13721 Date Filed: 08/31/2016 Page: 13 of 17 
14

of Roe. Indeed, and consistent with Roe, Wallace also referred to sovereign 

immunity, in the same discussion, as a “shield[] . . . from tort liability.” Id. at 

1045. Thus, to the extent any conflict between Wallace and Roe can be implied, it 

is tenuous at best and clearly insufficient to undermine CSX “to the point of 

abrogation.” Archer, 531 F.3d at 1352; see also United States v. Kaley, 579 F.3d 

1246, 1255 (11th Cir. 2009) (“In addition to being squarely on point, the doctrine 

of adherence to prior precedent also mandates that the intervening . . . case actually 

abrogate or directly conflict with, as opposed to merely weaken, the holding of the 

prior panel.”).

Finally, Defendants suggest that CSX is no longer controlling as a result of a

recent amendment to the Florida Rules of Appellate Procedure. See In re 

Amendments to Florida Rule of Appellate Procedure 9.130, 151 So. 3d 1217 (Fla. 

2014) (mem.). The amendment was made in response to Keck, discussed above, in 

which the Florida Supreme Court directed the Florida Bar Appellate Court Rules 

Committee to propose an amendment authorizing review of non-final orders

denying individual immunity under § 768.28(9)(a). Keck, 104 So. 3d at 366, 369.

The Rules Committee went beyond the directive of Keck and proposed an 

amendment authorizing the review of non-final orders denying any type of 

immunity. See In re Amendments to Florida Rule of Appellate Procedure 9.130,

151 So. 3d at 1217. As modified by the Florida Supreme Court, the amendment

Case: 15-13721 Date Filed: 08/31/2016 Page: 14 of 17 
15

that ultimately was adopted authorizes review of non-final orders denying 

individual or sovereign immunity under § 768.28(9), as well as orders denying

sovereign immunity generally. See Fla. R. App. P. 9.130(a)(3)(C)(x)–(xi).

There could be any number of reasons why the Rules Committee amended

Rule 9.130 to allow an immediate appeal, in a Florida appellate court, of an order 

denying Florida sovereign immunity. There is no basis for assuming the 

amendment reflects a change in Florida law as to the scope of sovereign immunity,

and no authority to suggest that the amendment abrogated either Roe or CSX. 

Moreover, Florida’s procedural rules do not govern whether an interlocutory order 

is immediately appealable in this Court. See Griesel, 963 F.2d at 340 (recognizing

that “federal law determines the appealability” of an order denying state 

immunity). As we made clear in CSX, our jurisdiction to review an order denying 

state immunity does not depend on whether the order is appealable in the state 

courts; our jurisdiction depends instead on whether, based on the state’s definition

of the immunity, its denial satisfies the requirements of the collateral order 

doctrine.2 CSX, 153 F.3d at 1286. CSX held that an order denying Florida 

2 For that reason, Beach Community Bank v. City of Freeport, 150 So. 3d 1111 (Fla. 2014), cited 

by Defendants, does not alter our analysis. In Beach Community Bank, the Florida Supreme 

Court assumed jurisdiction to review the trial court’s non-final order denying the City’s claim to 

sovereign immunity and the First District Court of Appeal’s decision reversing the trial court. 

The Florida Court’s decision to accept jurisdiction, however, was expressly based on the

amendment to Rule 9.130 permitting immediate review of an order denying sovereign immunity. 

See id. at 1113 (“Because this case falls squarely within the new rule amendment, we determine 

that the City should be entitled to the benefit of the new rule.”). But because Beach Community 

Case: 15-13721 Date Filed: 08/31/2016 Page: 15 of 17 
16

sovereign immunity does not meet those requirements. Id. Because CSX is still 

controlling on that point of law, we lack jurisdiction over this appeal.

II. Frivolity

In their motion to dismiss, Plaintiffs request a frivolity determination under

Federal Rule of Appellate Procedure 38. Rule 38 provides that: “[i]f a court of 

appeals determines that an appeal is frivolous, it may, after a separately filed 

motion or notice from the court and reasonable opportunity to respond, award just 

damages and single or double costs to the appellee.” Fed. R. App. P. 38. Rule 38 

sanctions are appropriately imposed against appellants who raise “clearly frivolous 

claims in the face of established law and clear facts.” Farese v. Scherer, 342 F.3d 

1223, 1232 (11th Cir. 2003) (internal quotation marks omitted). For purposes of

Rule 38, a claim is clearly frivolous if it is “utterly devoid of merit.” Bonfiglio v. 

Nugent, 986 F.2d 1391, 1393 (11th Cir. 1993). 

Although we have concluded that we lack jurisdiction over this appeal, the 

jurisdictional argument raised by Defendants is not entirely meritless. The recent 

Florida procedural amendments authorizing immediate review of an order denying 

sovereign immunity in Florida courts, and some of the language in Wallace, raise 

at least a colorable argument that CSX no longer precludes us from exercising 

Bank merely applies the above newly-amended rule, and does not purport to re-define the nature 

or scope of Florida sovereign immunity, it adds little to the analysis required of us under the 

collateral order doctrine.

Case: 15-13721 Date Filed: 08/31/2016 Page: 16 of 17 
17

jurisdiction over the appeal. Even though we were not ultimately persuaded by 

that argument, we do not find it to be frivolous. Accordingly, we deny Plaintiffs’ 

request for sanctions under Rule 38.

CONCLUSION

For the reasons discussed above, we grant Plaintiffs’ motion to dismiss this 

appeal for lack of jurisdiction and deny their motion for a frivolity determination 

and sanctions under Rule 38.
