Tenth Circuit 

September 20, 2019

Elisabeth A. Shumaker 

Clerk of Court

Fair Labor Standards Act (“FLSA”), 29 U.S.C. §§ 201–219, alleging that Helix 

misclassified him and similarly situated workers as exempt from the FLSA’s 

overtime obligations. Helix moved to dismiss Mr. Kenney’s claim based on the 

Controlled Substance Act (“CSA”), 21 U.S.C. §801, et seq, arguing that Mr. 

Kenney’s employment activities are in violation of the CSA and are thus not entitled 

to FLSA protections. The district court denied Helix’s motion to dismiss. We 

affirm. 

I. 

Between approximately February 2016 and April 2017, Mr. Kenney worked as 

a security guard for Helix. Mr. Kenney alleges that he and other similarly situated 

security guards regularly worked more than forty hours per week. Nevertheless, 

Helix classified these workers as exempt employees under the FLSA and paid them a 

salary instead of overtime. Mr. Kenney initiated this action against Helix under the 

collective action provisions of the FLSA, see 29 U.S.C. § 216(b), contending that 

Helix misclassified the security guards as exempt employees even though they 

frequently performed non-exempt job duties. He claims Helix is in violation of 29 

U.S.C. § 207(a) by willfully failing to pay overtime. 

Helix provides security, inventory control, and compliance services to the 

marijuana industry in Colorado. Kenney v. Helix TCS, Inc., 284 F. Supp. 3d 1186, 

1188 (D. Colo. 2018). Mr. Kenney’s job duties at Helix included monitoring security 
3 

cameras, patrolling assigned locations, investigating and documenting all facilityrelated incidents, and enforcing client, local, state, and federal policies and 

regulations. Id. Helix asserts that the FLSA does not apply to workers such as Mr. 

Kenney because Colorado’s recreational marijuana industry is in violation of the 

Controlled Substances Act. It therefore moved to dismiss Mr. Kenney’s FLSA claim 

for want of jurisdiction under Rule 12(b)(1) of the Federal Rules of Civil Procedure 

or, alternatively, under Rule 12(b)(6) for failure to state a claim. 

The district court denied Helix’s motion to dismiss and then certified Helix’s 

interlocutory appeal of its order. Exercising jurisdiction pursuant to 28 U.S.C. 

§ 1292(b), we affirm. 

II. 

Both parties agree that we review de novo the district court’s denial of Helix’s 

motions to dismiss. A Rule 12(b)(1) motion to dismiss only requires the court to 

determine whether it has authority to adjudicate the matter. Helix argued below that 

the district court lacked subject matter jurisdiction because there is no federal interest 

at stake. The district court correctly rejected this argument, identifying it as a 

challenge to the legal sufficiency of Mr. Kenney’s claims rather than the jurisdiction 

of the federal courts. Kenney, 284 F. Supp. 3d at 1189 (citing Arbaugh v. Y & H 

Corp., 546 U.S. 500, 516 (2006) (holding statute’s definitional requirement of who 

qualifies as employer “is an element of a plaintiff’s claim for relief, not a 
4 

jurisdictional issue”)). Helix only cursorily mentioned this argument in its opening 

brief and dropped the issue entirely in its reply brief. 

A Rule 12(b)(6) motion to dismiss requires the court to evaluate the 

sufficiency of the plaintiff’s allegations. “At this stage in the litigation, we accept as 

true the well pleaded factual allegations and then determine if the plaintiff has 

provided enough facts to state a claim to relief that is plausible on its face.” Hogan 

v. Winder, 762 F.3d 1096, 1104 (10th Cir. 2014) (internal citation and quotation 

marks omitted). “A claim has facial plausibility when the plaintiff pleads factual 

content that allows the court to draw the reasonable inference that the defendant is 

liable for the misconduct alleged.” Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009). 

III. 

Whether § 207(a) of the FLSA applies to Mr. Kenney is an issue of statutory 

interpretation, which always begins with the plain language of the statute. See, e.g., 

Artis v. D.C., 138 S. Ct. 594, 603 (2018). To state a claim for a violation of this 

FLSA provision, a plaintiff merely must show that he is an employee who (a) worked 

more than forty hours per week, and (b) is either “engaged in commerce or in the 

production of goods for commerce” or “employed in an enterprise engaged in 

commerce or in the production of goods for commerce.” 29 U.S.C. § 207(a)(1). The 

statute then enumerates certain categories of employees that are explicitly exempted 

from FLSA protections, regardless of whether they meet these requirements. The 
5 

employer bears the burden to prove that an exemption under the FLSA applies to the 

plaintiff. See, e.g., Lederman v. Frontier Fire Protection Inc., 685 F. 3d 1151, 1157–

58 (10th Cir. 2012). Our case law confirms that FLSA protections apply unless an 

establishment fits “plainly and unmistakably within the terms and the spirit of the 

exemption invoked.” Schoenhals v. Cockrum, 647 F.2d 1080, 1081 (10th Cir. 1981). 

Helix does not dispute the fact that Mr. Kenney is an employee who worked 

more than forty hours per week, and Mr. Kenney has clearly alleged that he is 

covered by the plain language of the FLSA.1 Nor does Helix argue that Mr. Kenney 

fits into one of the FLSA’s enumerated categories of excluded employees. As the 

Supreme Court has long emphasized, where the statute’s language is plain the sole 

function of the courts is to enforce it according to its terms. Lucas v. Jerusalem 

Café, LLC., 721 F.3d 927, 934 (8th Cir. 2013) (citing United States v. Ron Pair 

Enters., Inc., 489 U.S. 235, 241 (1989)). So Helix’s challenge “must fail unless [it] 

can point to a different statutory basis for limiting ‘the broadest definition that has 

ever been included in any one act.’” Lucas, 721 F.3d at 934 (quoting 81 Cong. Rec. 

 1

 Helix does contest the allegation that it engages in commerce within the 

meaning of the FLSA, see generally 29 U.S.C. § 203(b) (“‘Commerce’ means trade, 

commerce, transportation, transmission, or communication among the several States 

or between any State and any place outside thereof.”), arguing for the first time on 

appeal that Colorado’s marijuana industry is only authorized within the state’s 

borders. But Helix has waived this argument by raising it for the first time on appeal. 

See Hormel v. Helvering, 312 U.S. 552, 556 (1941); Tele–Communications, Inc. v. 

Commissioner of Internal Revenue, 12 F.3d 1005, 1007 (10th Cir. 1993).

7656–57 (1937) (statement of Sen. Black)). 2 

Although Helix sidesteps the disfavored phrase “implied repeal” and claims to 

merely be reading the statutes in harmony with each other, in effect it proposes that 

we interpret the CSA as implicitly repealing the FLSA’s overtime mandate for 

employers in the marijuana industry. See Epic Systems Corp v. Lewis, 138 S. Ct. 

1612, 1623–24 (2018). Construing this as Helix’s true argument is particularly 

accurate in light of marijuana’s history as a legal industry. See, e.g., Marihuana Tax 

Act, 50 Stat. 551 (repealed 1970) (regulating all persons dealing with marijuana, 

including companies and corporations); see also Raich, 545 U.S. at 11 (explaining 

history of marijuana regulation). Prior to enactment of the CSA in 1970, the FLSA 

unquestionably covered these workers. The Supreme Court recently reiterated that an 

implied repeal argument “faces a stout uphill climb.” Epic Systems, 138 S. Ct. at 

1624. We approach these arguments with a “strong presumption that repeals by 

implication are disfavored and that Congress will specifically address preexisting law 

when it wishes to suspend its normal operations in a later statute.” Id. (citation, 

quotation marks, and brackets omitted). And, as Helix itself declares, Congress is 

 2

 Helix develops several lines of argument that do not bear on the resolution of 

this appeal. Helix frames the issue as one of preemption by setting state-sanctioned 

marijuana use in opposition to the CSA, lengthily addresses federal enforcement of 

the CSA with respect to marijuana offenses, and examines state court treatment of 

employment protections in the context of marijuana use. None of these arguments 

pertain to the present case, which concerns not the federal legality of marijuana but 

the interaction between two federal laws and the resultant application of the FLSA to 

the plaintiffs here.

presumed to know the law when legislating. Aplt. Br. at 19; see also In re Harline, 

950 F.2d 669, 675 (10th Cir. 1991). 

Helix argues that inclusion of Mr. Kenney under the FLSA is an overly 

technical reading of the statute, and that legislative intent with respect to this issue 

must be inferred from the distinctive purposes of the FLSA and the CSA as the two 

statutes in question. Helix contrasts the purpose of the FLSA, which it identifies as 

ensuring “the free flow of goods in commerce” and “the orderly and fair marketing of 

goods in commerce,” Aplt. Br. at 20 (citing 29 U.S.C. § 202), from the purpose of the 

later-enacted CSA, which it describes as “eliminat[ing] commercial transactions of 

marijuana in the interstate market in their entirety.” Id. (citing Raich, 545 U.S. at 20) 

(brackets omitted). Helix then asserts that Mr. Kenney’s interpretation of the FLSA 

would “create a clear repugnancy” between it and the CSA and impermissibly render 

the two laws mutually inconsistent. Aplt. Br. at 21. “Extending overtime benefits in 

this case would require the Court to find that Congress intended to both forbid (under 

the CSA) and reward (under the FLSA) the same conduct: drug trafficking.” Id. 

As outlined below, however, “case law is clear that employers are not excused 

from complying with federal laws” because of their other federal violations. Kenney, 

284 F. Supp. 3d at 1190; accord United States v. Sullivan, 274 U.S. 259 (1927) 

(holding there was no reason “why the fact that a business is unlawful should exempt 

it from paying the taxes that if lawful it would have to pay”); Lucas, 721 F.3d at 934 

(“The employers’ argument to the contrary rests on a legal theory as flawed today as 
8 

it was in 1931 when jurors convicted Al Capone of failing to pay taxes on illicit 

income.”). Contrary to Helix’s claims, recognizing Mr. Kenney as covered by the 

FLSA is in line with both the plain reading and the overall purposes of that statute, 

and doing so does not require disavowal of the CSA. 

As we recognized in Baker v. Flint Engineering & Const. Co., 137 F.3d 1436, 

1440 (10th Cir. 1998), the Supreme Court has emphasized the “striking breadth” of 

the FLSA’s definition of employee, which is purposefully expansive to maximize the 

full reach of the Act, see United States v. Rosenwasser, 323 U.S. 360, 363 (1945). 

Congress has shown that it knows how to limit this broad definition of employee 

when it intends to do so, and it did not do so here. See 29 U.S.C. § 203(e); see also 

Lucas, 721 F.3d at 934 (applying FLSA to unauthorized immigrants). Congress has 

actually amended the FLSA many times since the enactment of the CSA without 

excluding employees working in the marijuana industry, despite specifically 

exempting other categories of workers. See 29 U.S.C. § 213. The Supreme Court 

has held that the FLSA’s “specificity in stating exemptions strengthens the 

implication that employees not thus exempted . . . remain within the Act.” Powell v. 

United States Cartridge Co., 339 U.S. 497, 516–17 (1950); accord Citicorp Indus. 

Credit, Inc. v. Brock, 483 U.S. 27, 35 (1987) (“[W]here the FLSA provides 

exemptions ‘in detail and with particularity,’ we have found this to preclude 

‘enlargement by implication.’”) Deherrera v. Decker Truck Line, Inc., 820 F.3d 

1147, 1154 (10th Cir. 2016) (“Because FLSA exemptions are narrowly construed 
9 

against . . . employers, in considering an FLSA exemption, a court must find that the 

claimed exemption falls plainly and unmistakably within the terms of the statute.”) 

(internal citations and quotation marks omitted). 

Moreover, the purposes of the FLSA do not conflict with the CSA quite as 

directly as Helix implies. Helix cherry-picks among the enumerated purposes of the 

FLSA, citing only those most favorable to its arguments. But the FLSA was also 

enacted to promote “the health, efficiency, and general well-being of workers” and to 

prevent unfair competition. 29 U.S.C. § 202; see also Brock, 483 U.S. at 36–37 

(clarifying that FLSA contains more than one goal, including “Congress’ desire to 

eliminate the competitive advantage enjoyed by goods produced under substandard 

conditions”). The FLSA is a remedial scheme for the benefit of all workers. 

Anderson v. Mt. Clemens Pottery Co., 328 U.S. 680, 687 (1946); see also Lamon v. 

City of Shawnee, Kan., 972 F.2d 1145, 1149 (10th Cir. 1992). Applying the FLSA to 

workers such as Mr. Kenney does not conflict with these enumerated FLSA purposes. 

Helix counters that “Congress did not seek to level the same playing field that 

it tried to demolish.” Aplt. Reply Br. at 5. But adhering to the plain language of the 

statute here does not level the playing field within the illicit marijuana market but 

rather beyond it, preventing these unlawful businesses from procuring an unfair 

advantage over all other legitimate employers who are required to comply with 

federal overtime laws. Indeed, applying FLSA protections to workers such as Mr. 

Kenney will not grant these individuals any surplus benefit that they cannot easily 
10 

obtain elsewhere, but the reverse would excuse Helix from FLSA costs and 

obligations and thereby allow it to reap additional benefit from its CSA violations. 

Denying FLSA protection to workers in the marijuana industry would consequently 

encourage employers to engage in illegal markets where they are subject to fewer 

requirements. But together the FLSA and CSA discourage businesses from 

participating in the marijuana industry by alternatively subjecting them to federal 

labor obligations and imposing criminal sanctions.3 Accordingly, accepting the plain 

language interpretation that Mr. Kenney and similarly situated employees are covered 

by the FLSA promotes the legislature’s intent in enacting the statute. See Brock, 483 

 3

 Helix’s opening brief cites a variety of jurisprudential arenas as supporting 

the contention that federal courts “consistently decline to reward participation in the 

marijuana industry.” Aplt. Br. at 10. The only context Helix continued to argue 

through oral argument is the Trademark Act. Beyond noting that Mr. Kinney 

convincingly distinguishes each of the contexts and relevant authorities that Helix 

cites, we will similarly restrict our analysis. A trademark qualifies for registration 

and its associated benefits if the trademark owner has “used [the mark] in commerce” 

or has a bona fide intent to do so, 15 U.S.C. § 105, and courts have long held that the 

commerce must be “lawful” for it to satisfy the “use in commerce” requirement. See, 

e.g., United Phosphorus, Ltd. v. Midland Fumigant, Inc., 205 F.3d 1219, 1225 (10th 

Cir. 2000). Helix urges us to adopt a similar interpretation for the FLSA. Although 

the Trademark Act and FLSA both regulate interstate commerce, however, they 

function in fundamentally different ways. The Trademark Act confers a benefit on 

owners who register their marks, securing a registrant’s right to benefit from a good 

reputation and thus protecting him from unfair competition. See Matal v. Tam, 137 

S. Ct. 1744, 1752–53 (2017). The FLSA, in contrast, prevents unfair competition, 

not by conferring a benefit on certain actors but by imposing obligations across the 

labor market. Reading “lawful” into the threshold commerce requirement here would 

not further the statute’s purposes by denying illegal businesses a benefit, as in the 

trademark context, but would thwart the FLSA’s goals by exempting illicit markets 

from costs imposed on lawful employers. 
11 

U.S. at 35–36 (“Petitioner urges us to look beyond the plain language of the statute . . 

. . However, we conclude that the legislative intent fully supports the result achieved 

by application of the plain language.”). 

The district court correctly reasoned and case law has repeatedly confirmed 

that employers are not excused from complying with federal laws just because their 

business practices are federally prohibited. See, e.g., Sullivan, 274 U.S. at 263; see 

also Greenwood v. Green Leaf Lab LLC, 2017 WL 3391671 at *3 (D. Or. July 13, 

2017), adopted by district court, 2017 WL 3391671 (D. Or. Aug. 7, 2017) (“[J]ust 

because an Employer is violating one federal law, does not give it license to violate 

another.”) (internal citation omitted). This has been true with respect to the FLSA in 

multiple contexts, strengthening the conclusion that it remains true in this novel 

context of the marijuana industry. See Donovan v. Burgett Greenhouses, Inc., 759 

F.2d 1483, 1485 (10th Cir. 1985); Bustamente, 2018 WL 2349507 at *1 (workers in 

an illegal gambling operation).4 Persuasive case law endorses the concept that the 

FLSA is focused on regulating the activity of businesses, in part on behalf of the 

individual workers’ wellbeing, rather than regulating the legality of individual 

workers’ activities. See, e.g., Haro v. City of Los Angeles, 745 F.3d 1249, 1256 (9th 

 4

 Helix attempts to distinguish these cases on the basis that those employees 

were engaging in entirely lawful commercial activities, whereas the employees here 

are engaged in activities that violate the CSA. This argument is not convincing. The 

illegal nature of the gambling activity in Bustamente was directly acknowledged by 

the court in a footnote, and the innocuous nature of the work being performed by 

undocumented immigrants in the other cases discussed does not offset their active 

violations of federal law in obtaining work. 
12 

Cir. 2014). (“The FLSA is to be construed liberally in favor of employees; 

exemptions are narrowly construed against employers.”). 

Notably, Helix failed entirely to address the Oregon district court case that was 

cited here by both the district court and Mr. Kenney and is directly on-point. 

Greenwood, 2017 WL 3391671. The district court in Greenwood relied on a legal 

advice memo written for the National Labor Relations Board to conclude that any 

possible violations of the CSA are not relevant to whether the FLSA’s protections 

apply to workers in the marijuana industry. Id. at *2–3. Considering arguments 

nearly identical to those made by Helix here, the court in Greenwood denied 

defendant’s motion to dismiss. See, e.g., id. at *3 (“I conclude that any possible 

violations of the Controlled Substances Act are not relevant to whether the FLSA’s 

protections apply to Plaintiff. . . . There is no inherent conflict between the FLSA’s 

requirements and the Controlled Substances Act's prohibition of marijuana.”). 

Like the district court in Greenwood, we are not drawing any conclusions 

about the merits of Mr. Kenney’s FLSA claims. We hold only that Mr. Kenney and 

similarly situated individuals are not categorically excluded from FLSA protections. 

Accordingly, we AFFIRM the district court’s denial of Helix’s motion to dismiss.
