UNITED STATES DISTRICT COURT
MIDDLE DISTRICT OF FLORIDA
TAMPA DIVISION

ENVIRONMENTAL PROTECTION
COMMISSION OF HILLSBOROUGH
COUNTY, FLORIDA,

Plaintiff,
v. Case No. 8:20-cv-2238-VMC-JSS
MERCEDES-BENZ USA, LLC,
DAIMLER AKTIENGESELLSCHAFT,
ROBERT BOSCH, LLC,
and ROBERT BOSCH GMBH,

Defendants.
______________________________/
ORDER
This matter is before the Court on consideration of
Defendants Daimler Aktiengesellschaft and Mercedes-Benz USA,
LLC’s (“the Mercedes Defendants’”) Motion to Dismiss
Plaintiff’s Third Amended Complaint (Doc. # 122), filed on
January 20, 2022. Plaintiff Environmental Protection
Commission of Hillsborough County, Florida responded on
February 10, 2022. (Doc. # 135). The Mercedes Defendants
replied on March 4, 2022. (Doc. # 144). The Motion is granted
to the extent set forth herein.
I. Background
The Commission, a unit of Hillsborough County’s
government responsible for providing and maintaining
standards of atmospheric purity, initiated this action on
September 24, 2020. (Doc. # 1). The Commission then filed a
third amended complaint on December 16, 2021, seeking
monetary penalties and injunctive relief for violations of
the Commission’s anti-tampering ordinance, EPC Rule Chapter
1-8, “Mobile Source.” (Doc. # 116).
According to the third amended complaint, all Defendants

engaged in a conspiracy to create and install “defeat device”
software in new Mercedes diesel vehicles to reduce the
effectiveness of the vehicles’ emission control systems when
not in an emissions-testing environment. (Id. at 1-4).
The Commission’s claims are not, however, based on the
creation of these defeat devices and their installation in
new Mercedes vehicles pre-sale. Rather, the Commission “is
only asserting claims relating to post-sale activities of the
Defendants.” (Id. at 4). Specifically, the Commission bases
its claim in part on “every post-sale update that does not
remove the workaround” — the defeat device — from the relevant

Mercedes vehicles. (Id. at 29).
The Defendants also allegedly “violated EPC Rule Section
1-8.05(1) . . . by tampering with the emission control systems
of Affected Vehicles registered in Hillsborough County, and
manufacturing and installing post-sale software updates in
Affected Vehicles registered in Hillsborough County.” (Id. at
44). “Because Mercedes represents and maintains that their
engines require steady service to remain operative, numerous
post-sale updates to the emissions control systems, created
through collaboration amongst all of the Defendants, have
been implemented and installed throughout the United States,
Florida, and Hillsborough County.” (Id. at 27-28). “It is

industry standard for manufacturers, including Mercedes, to
make such post-sale software updates available to their
dealerships via web-based computer programs.” (Id. at 28).
Mercedes allegedly “sometimes issue[s] such post-sale
software changes via over-the-air updates.” (Id.).
Additionally, the Commission also alleges that the
“Defendants’ conduct in tampering post-sale with the emission
control systems of Affected Vehicles registered in
Hillsborough County, through a program of newly created field
fixes and recall campaigns, violates EPC Rule Chapter 1-8.”
(Id. at 44-45).

The Mercedes Defendants now seek dismissal of the claims
against them based on preemption, failure to state a claim,
and other arguments. (Doc. # 122). The Motion is fully briefed
(Doc. ## 135, 144), and ripe for review.
II. Legal Standard
On a motion to dismiss pursuant to Rule 12(b)(6), this
Court accepts as true all the allegations in the complaint
and construes them in the light most favorable to the
plaintiff. Jackson v. Bellsouth Telecomms., 372 F.3d 1250,
1262 (11th Cir. 2004). Further, the Court favors the plaintiff
with all reasonable inferences from the allegations in the

complaint. Stephens v. Dep’t of Health & Human Servs., 901
F.2d 1571, 1573 (11th Cir. 1990). But,
[w]hile a complaint attacked by a Rule 12(b)(6)
motion to dismiss does not need detailed factual
allegations, a plaintiff’s obligation to provide
the grounds of his entitlement to relief requires
more than labels and conclusions, and a formulaic
recitation of the elements of a cause of action
will not do. Factual allegations must be enough to
raise a right to relief above the speculative
level.

Bell Atl. Corp. v. Twombly, 550 U.S. 544, 555 (2007) (internal
citations omitted). Courts are not “bound to accept as true
a legal conclusion couched as a factual allegation.” Papasan
v. Allain, 478 U.S. 265, 286 (1986). The Court must limit its
consideration to well-pleaded factual allegations, documents
central to or referenced in the complaint, and matters
judicially noticed. La Grasta v. First Union Sec., Inc., 358
F.3d 840, 845 (11th Cir. 2004).
Additionally, “[a] plaintiff is ‘not required to negate
an affirmative defense in [its] complaint.’ Thus,
‘[g]enerally, the existence of an affirmative defense will
not support a motion to dismiss.’” Twin City Fire Ins. Co. v.
Hartman, Simons & Wood, LLP, 609 F. App’x 972, 976 (11th Cir.
2015) (citations omitted).

III. Analysis
The Mercedes Defendants raise multiple arguments for
dismissal. The Court addresses them in turn.
A. Preemption
First, the Mercedes Defendants argue that the
Commission’s claims are preempted by the Clean Air Act
(“CAA”).
The Court rejects this argument and, instead, follows
the reasoning of the Ninth Circuit in In re Volkswagen “Clean
Diesel” Mktg., Sales Pracs., & Prod. Liab. Litig., 959 F.3d
1201 (9th Cir. 2020), cert. denied sub nom. Volkswagen Grp.
of Am., Inc. v. Env’t Prot. Comm’n of Hillsborough Cnty., 142

S. Ct. 521 (2021) — another emissions case brought by the
Commission and other county governments. The Ninth Circuit
held that the CAA neither expressly nor impliedly preempts
claims related to post-sale tampering with emission control
systems. Id.; see also State ex rel. Yost v. Volkswagen
Aktiengesellschaft, 165 Ohio St. 3d 213, 218 (Ohio 2021)
(holding that the post-sale anti-tampering provision of
Ohio’s Air Pollution Control Act was neither expressly nor
impliedly preempted by the Clean Air Act), cert. denied sub
nom. Volkswagen Aktiengesellschaft v. Ohio, 142 S. Ct. 515
(2021).
1. Express Preemption

The CAA “expressly preempts certain state and local laws
regulating emissions from new motor vehicles.” In re
Volkswagen “Clean Diesel” Mktg., Sales Pracs., & Prod. Liab.
Litig., 959 F.3d at 1215. Section 209(a) of the CAA provides:
No State or any political subdivision thereof shall
adopt or attempt to enforce any standard relating
to the control of emissions from new motor vehicles
or new motor vehicle engines subject to this part.
No State shall require certification, inspection,
or any other approval relating to the control of
emissions from any new motor vehicle or new motor
vehicle engine as condition precedent to the
initial retail sale, titling (if any), or
registration of such motor vehicle, motor vehicle
engine, or equipment.
42 U.S.C. § 7543(a). “A ‘new motor vehicle’ is ‘a motor
vehicle the equitable or legal title to which has never been
transferred to an ultimate purchaser,’ § 7550(3), in other
words, a pre-sale vehicle.” In re Volkswagen “Clean Diesel”
Mktg., Sales Pracs., & Prod. Liab. Litig., 959 F.3d at 1215.
“In light of this definition, [Section] 209(a) precludes
state or local governments from imposing any restriction that
has the purpose of enforcing emission characteristics for
pre-sale, motor vehicles.” Id. at 1216. “After a new motor
vehicle is sold ‘to an ultimate purchaser,’ 42 U.S.C. §
7550(3), the express preemption clause no longer applies.
Instead, the CAA preserves state and local governments’
authority over post-sale motor vehicles.” Id. at 1216.

The Ninth Circuit rejected Volkswagen’s argument that
the Commission’s rules, including the same EPC Rule Section
1-8.05(1) at issue here, were preempted as applied to post-
sale vehicles:
We turn to Volkswagen’s argument that [Section]
209(a) also expressly preempts the Counties’ anti-
tampering rules as applied to post-sale vehicles.
It clearly does not. By its terms, [Section] 209(a)
preempts state and local regulations “relating to
the control of emissions from new motor vehicles.”
42 U.S.C. § 7543(a) (emphasis added). The provision
does not apply to post-sale vehicles.
Id. at 1218. For the same reason, the Court holds that express
preemption does not apply to the Commission’s claims here,
which are based on alleged post-sale tampering in the form of
software updates, field fixes, and recalls.
This is true even though the Commission bases its post-
sale tampering claim in part on what the Mercedes Defendants’
dub the “inaction theory” of tampering, under which the
Commission argues that post-sale software updates constituted
tampering because they failed to remove the original defeat
device. The Court does not agree that this inaction theory
would require car manufacturers to alter their design or
manufacture of new vehicles before sale. Because even under
the inaction theory the Commission bases its claims on
tampering with post-sale vehicles, the claims are not

expressly preempted.
2. Implied Preemption
“The Supreme Court has articulated two circumstances —
referred to as ‘field preemption’ and ‘conflict preemption’
— where Congress’s implicit intent to preempt state law clears
[the high threshold to find implied preemption]. First, ‘when
federal law occupies a “field” of regulation “so
comprehensively that it has left no room for supplementary
state legislation,”’ a court may infer that Congress intended
to preempt state law.” Id. at 1212 (citations omitted).
“Second, when a state law ‘actually conflicts with federal

law,’ either because ‘compliance with both state and federal
law is impossible,’ or because ‘the state law “stands as an
obstacle to the accomplishment and execution of the full
purposes and objectives of Congress,”’ a court may again
conclude that Congress implicitly intended to preempt state
law.” Id. (citations omitted).
Here, the Mercedes Defendants argue that the
Commission’s claims are impliedly preempted under obstacle
and impossibility preemption theories. (Doc. # 122 at 15).
Regarding obstacle preemption, in Volkswagen, the Ninth
Circuit rejected the argument that the Commission’s and other

counties’ tampering claims were impliedly preempted. That
court wrote:
The CAA’s preemption clause (§ 209(a)) and saving
clause (§ 209(d)) allocate authority between the
federal government and state governments as
follows: Section 209(a) gives the EPA exclusive
authority to establish standards for new vehicles,
42 U.S.C. § 7543(a), while § 209(d) preserves the
authority of state and local governments over post-
sale vehicles, 42 U.S.C. § 7543(d). The plain
language of § 209(d), providing that nothing in
Title II “shall preclude or deny to any State or
political subdivision thereof the right otherwise
to control, regulate, or restrict the use,
operation, or movement of registered or licensed
motor vehicles,” appears to give states substantial
authority to enforce standards related to post-sale
vehicles, including sanctioning tampering with
emission control systems.
In re Volkswagen “Clean Diesel” Mktg., Sales Pracs., & Prod.
Liab. Litig., 959 F.3d at 1219. Thus, “the CAA’s text and
structure, particularly in light of the presumption that
Congress does not impliedly preempt states’ historic police
powers, weigh against a conclusion that Congress intended to
preempt the Counties’ anti-tampering rules.” Id. at 1221.
Likewise, “[t]he regulation of air pollution from post-
sale vehicles does not involve a ‘uniquely federal’ area of
enforcement, because the basic division of responsibility in
Title II of the CAA reflects the cooperative federalism
principles that have long informed this nation’s air

pollution control laws.” Id. (citation omitted). The Ninth
Circuit also could not “discern a congressional intent, let
alone a ‘clear and manifest purpose of Congress,’ to give the
EPA exclusive authority over large-scale, post-sale tampering
by manufacturers, while giving state and local governments
concurrent authority only when the tampering is conducted on
a more casual, individual basis.” Id. at 1223. Thus, that
court correctly concluded that state and local authority “to
enforce anti-tampering rules on a model-wide basis” was not
preempted. Id.
The Court adopts the Ninth Circuit’s reasoning and

concludes that the Commission’s claims are not preempted
under the obstacle preemption doctrine. The Mercedes
Defendants’ attempts to distinguish the post-sale tampering
in Volkswagen and this case are unavailing. While the Mercedes
Defendants argue that the Volkswagen court intended only for
post-sale tampering claims involving “enhancements” to defeat
devices to escape preemption (rather than inaction-based
tampering or field fixes and recalls) (Doc. # 122 at 18), no
such limitation was announced by that court. Instead, the
Volkswagen ruling stands for the proposition that post-sale
tampering claims in general are not impliedly preempted and
is persuasive in its reasoning.

Nor is the Court persuaded by the Mercedes Defendants’
argument under the impossibility theory of preemption. They
argue that “it would be impossible for the Mercedes Defendants
to comply with both the Consent Decree [entered by them and
the EPA and the California Air Resources Board in United
States v. Daimler AG, No. 1:20-cv-02564 (D.D.C. Mar. 9, 2021)]
and [the Commission]’s ordinance.” (Doc. # 122 at 15). The
Court rejects this argument for multiple reasons. First, the
Mercedes Defendants have cited no case in which a consent
decree entered in a federal lawsuit was found to preempt a
state or local government’s rule or ordinance. Thus, the Court

is not convinced that the consent decree could support
obstacle preemption. Even if it did, the Court has only taken
judicial notice of the consent decree’s existence — not its
contents (Doc. # 143) — such that the Court cannot determine
whether the terms of the consent decree conflict with the
Commission’s anti-tampering rule at this time.
Finally, even crediting the Mercedes Defendants’
representations about the contents of the consent decree, the
Court is not convinced that it would be impossible for the
Mercedes Defendants to comply with both EPA regulations and
the Commission’s rule against post-sale tampering. See State

ex rel. Yost, 165 Ohio St. 3d at 220–21 (“[W]e reject
Volkswagen’s argument that the potential imposition of state-
law penalties under [Ohio’s Air Pollution Control Act] makes
it impossible for the federal EPA to administer its vehicle-
emissions program or interferes with the federal EPA’s
ability to resolve enforcement actions. First of all, it is
not impossible for a violator to pay federal penalties and
state-law penalties relating to the same conduct, so exposure
to liability at the state level does not necessarily frustrate
the purpose of the federal scheme.” (citations omitted)). As
the Commission argues, “[s]hould Defendants, pursuant to

their Consent Decree, craft and have approved a post-sale
update that cures the defect [in the emission control system],
which is assumedly the goal, that update would not fit the
definition of tampering” under the Commission’s rule. (Doc.
# 135 at 11).
The Commission’s post-sale tampering claims are not
preempted. Whether the post-sale tampering claims are
sufficiently pled is a different question.
B. Plausibility
The Mercedes Defendants also argue that the claims
against them should be dismissed under Rule 12(b)(6) because
the Commission has not stated plausible claims for violation

of EPC Rule Section 1-8.05(1). The Court agrees.
EPC Rule Section 1-8.05(1) provides: “No person shall
tamper, cause, or allow the tampering of the emission control
system of any motor vehicle.” EPC Rule § 1-8.05(1). Section
1-8.03(2)(h) defines “tampering” as “the intentional
inactivation, disconnection, removal or other modification of
a component or components of the emission control system
resulting in it being inoperable.” EPC Rule § 1-8.03(2)(h)
(emphasis added). Section 1-8.03(2)(c) defines “inoperable
emission control system” as “any emission control system or
component thereof whose operation or efficiency has been

circumvented, defeated, or deleteriously affected by improper
maintenance, improper up-keep, wear and tear, misfueling, or
tampering.” EPC Rule § 1-8.03(2)(c).
First, the Mercedes Defendants attack what they dub the
“inaction theory” — that is, the Commission’s theory that any
post-sale updates to Mercedes vehicles that do not remove the
original defeat devices constitute post-sale tampering. In
the third amended complaint, the Commission alleges that
“every post-sale update that does not remove the workaround,”
by which the Commission refers to the original defeat device,
is “illegal.” (Doc. # 116 at 29). In its response, the
Commission confirms that it is — at least in part — proceeding

under this inaction theory: “Each post-sale update that fails
to remove or otherwise disable the improper programming of
the defeat device is post-sale tampering.” (Doc. # 135 at
15).
As the Mercedes Defendants persuasively argue, “[b]y
relying on a theory of mere inaction — that failure to
‘remove’ an alleged defeat device is tampering — [the
Commission] expressly eschews any requirement to show an
intentional affirmative act or resulting causation” and fails
to show that an emission control system was rendered
“inoperable” “by virtue of post-sale updates.” (Doc. # 122 at

23-24).
The Court agrees that software updates that merely fail
to remove the original defeat device from Mercedes vehicles
do not plausibly violate EPC Rule Section 1-8.05(1). These
updates are not “tampering” as defined by the rule because
they do not cause the emissions control system to be
inoperable. Rather, the original pre-sale defeat devices — on
which the Commission has not and cannot base its claims —
have rendered the emissions control system inoperable and the
later software update has no effect on that system. Thus,
Count I is dismissed with prejudice to the extent it is based
on software updates that simply do not remove the original

defeat device.
The Mercedes Defendants also highlight the limited
nature of the other allegations that do not rely on the
inaction theory. The third amended complaint states that
Defendants committed tampering by “manufacturing and
installing post-sale software updates,” including through
“field fixes and recall campaigns.” (Doc. # 116 at 44). No
information is provided about when any recalls or field fixes
occurred for vehicles registered in Hillsborough County. Nor
are there allegations about how the field fixes, recalls, or
post-sale software updates tampered with the vehicles’

emission control systems, such as by rendering a system even
less functional than it had been with the original defeat
device. The Mercedes Defendants are correct that these
allegations are insufficiently detailed to state a plausible
claim.
However, the Court is not persuaded that amendment would
be futile as to the allegations not based on the inaction
theory. The Commission could plead greater detail about the
software updates, field fixes, and recalls on which its claims
rely. And the Court is not convinced at this juncture that
the Commission’s claims are barred by the statute of
limitations, given that the dates of the relevant post-sale

software updates, field fixes, and recalls are not alleged.
See United States ex rel. Hunt v. Cochise Consultancy, Inc.,
887 F.3d 1081, 1085 (11th Cir. 2018) (“A dismissal for failure
to state a claim on statute of limitations grounds is
appropriate ‘only if it is apparent from the face of the
complaint that the claim is time-barred.’” (citation
omitted)), aff’d, 139 S. Ct. 1507 (2019).
The Commission may file a fourth amended complaint to
address the identified deficiencies in its tampering
allegations, which underlie both Counts I and II. Because
amendment is necessary, the Court need not address the

Mercedes Defendants’ other arguments at this time.
Accordingly, it is hereby
ORDERED, ADJUDGED, and DECREED:
(1) Defendants Daimler Aktiengesellschaft and Mercedes-Benz
USA, LLC’s Motion to Dismiss Plaintiff’s Third Amended
Complaint (Doc. # 122) is GRANTED to the extent stated
herein.
(2) If Plaintiff Environmental Protection Commission of
Hillsborough County, Florida wishes to amend, the fourth
amended complaint is due within fourteen days of this
Order.
DONE and ORDERED in Chambers in Tampa, Florida, this
18th day of April, 2022.
