Before BRISCOE, HARTZ and HOLMES, Circuit Judges.

                                            4
BRISCOE, Circuit Judge.

       These three appeals arise from two cases that concern the passage,

implementation, and alleged effects of Amendment 64 to the Colorado Constitution,

Colo. Const. art. XVIII, § 16. Amendment 64 repealed many of the State’s criminal and

civil proscriptions on “recreational marijuana,”1 and created a regulatory regime designed

to ensure that marijuana is unadulterated and taxed, and that those operating marijuana-

related enterprises are, from the State’s perspective, licensed and qualified to do so. Of

course, what Amendment 64 did not and could not do was amend the United States

Constitution or the Controlled Substances Act (CSA), 21 U.S.C. §§ 801–904, under

which manufacturing, distributing, selling, and possessing with intent to distribute

marijuana remains illegal in Colorado. See U.S. Const. art. VI, cl. 2. The three appeals

at issue and two related motions to intervene raise four principal disputes stemming from

the alleged conflict between the CSA and Colorado’s new regime.

       Two of the appeals were brought in Safe Streets Alliance v. Alternative Holistic

Healing, LLC. First, in No. 16-1266, two Colorado landowners challenge the district

court’s dismissal of their claims brought under the citizen-suit provision of the Racketeer

1
 Amendment 64 addresses a host of substances derived from plants of the Cannabis
genus. Id. § 16(2)(f). The parties do not suggest any distinction between Cannabis
derivatives is of import here. So we refer to these substances collectively as “marijuana.”
The parties also agree that Colorado’s “medical marijuana” regime is not at issue in these
suits. Id. § 16(7) (capitalization omitted). We therefore confine our discussion to what
the parties term “recreational marijuana”—i.e., marijuana grown, processed, distributed,
sold, possessed, or used other than for purportedly “medicinal” purposes.

                                             5
Influenced and Corrupt Organizations Act (RICO), 18 U.S.C. § 1964(c), against certain

affiliates of a State- and county-licensed marijuana manufactory that allegedly has injured

the landowners’ adjacent property. We conclude that the landowners have plausibly

alleged at least one § 1964(c) claim against each of those defendants. We therefore

reverse, in part, the dismissal of those claims and remand for further proceedings.

         Second, in No. 16-1048, those landowners and an interest group to which they

belong appeal the district court’s dismissal of their purported causes of action “in equity”

against Colorado and one of its counties for ostensibly also having injured the

landowners’ property by licensing that manufactory. The landowners and the interest

group allege that Amendment 64’s regime is preempted by the CSA, pursuant to the

Supremacy Clause, U.S. Const. art. VI, cl. 2, and the CSA’s preemption provision,

21 U.S.C. § 903.2 We conclude that neither the landowners nor the interest group purport

to have any federal substantive rights that have been injured by Colorado or the county’s

actions. And because they have no substantive rights in the CSA to vindicate, it follows

inexorably that they cannot enforce § 903 “in equity” to remedy their claimed injuries.

We therefore affirm the dismissal of their preemption claims.

2
    Section 903 of Title 21 of the United States Code states:

         No provision of this subchapter shall be construed as indicating an intent on
         the part of the Congress to occupy the field in which that provision
         operates, including criminal penalties, to the exclusion of any State law on
         the same subject matter which would otherwise be within the authority of
         the State, unless there is a positive conflict between that provision of this
         subchapter and that State law so that the two cannot consistently stand
         together.

                                               6
       The third appeal, No. 16-1095, was filed in Smith v. Hickenlooper. In that case, a

group of Colorado, Kansas, and Nebraska sheriffs and county attorneys sued Colorado on

similar theories that Amendment 64’s regime is preempted by the CSA. The district court

dismissed their claims, and we consolidated the appeal with No. 16-1048. Because those

plaintiffs also do not claim injuries to their federal substantive rights, we likewise affirm.

       Finally, the States of Nebraska and Oklahoma moved to intervene in Safe Streets

Alliance and Smith while they were pending on appeal. Those States claim that

Amendment 64 injures their sovereign interests and those of their citizens, and that its

enforcement is preempted by the CSA. We granted their motion in No. 16-1048 and

heard their arguments, which confirmed that their controversy is with Colorado. Given

that fact, we must confront 28 U.S.C. § 1251(a), which forbids us from exercising

jurisdiction over controversies between the States. We therefore cannot permit Nebraska

and Oklahoma to intervene, or even confirm that they have a justiciable controversy that

may be sufficient for intervention. Consequently, we vacate the order granting

intervention in Safe Streets Alliance and deny the States’ motions in both cases.

                                  I. Standards of Review

       Before addressing each of those issues, we first discuss the applicable standards of

review. The district court dismissed the claims before it on the basis of Federal Rules of

Civil Procedure 12(b)(1) and (6). Rule 12(b)(1) “allows a court to dismiss a complaint

for lack of subject matter jurisdiction. If the district court did so without taking evidence,

as the court did here, our review is de novo.” Pueblo of Jemez v. United States, 790 F.3d

1143, 1151 (10th Cir. 2015) (citing Becker v. Ute Indian Tribe, 770 F.3d 944, 946 (10th

                                              7
Cir. 2014)). Such a “facial attack on the complaint’s allegations as to subject matter

jurisdiction questions the sufficiency of the complaint,” and the “district court must

accept the allegations in the complaint as true.” Id. at 1148 n.4 (citation omitted). We

also accept those factual allegations as true in conducting our de novo review. Id.

       “Federal courts are courts of limited jurisdiction, possessing only that power

authorized by Constitution and statute.” Id. at 1151 (quoting Gunn v. Minton, __ U.S. __,

133 S. Ct. 1059, 1064 (2013)). “[F]ederal subject matter jurisdiction is elemental,” and

“must be established in every cause under review in the federal courts.” Id. (quoting

Firstenberg v. City of Santa Fe, 696 F.3d 1018, 1022 (10th Cir. 2012)). The “burden of

establishing” a federal court’s subject matter jurisdiction “rests upon the party asserting

jurisdiction.” Id. (citation omitted). “A court lacking jurisdiction cannot render judgment

but must dismiss the cause at any stage of the proceedings in which it becomes apparent

that jurisdiction is lacking.” Id. (quoting Full Life Hospice, LLC v. Sebelius, 709 F.3d

1012, 1016 (10th Cir. 2013)). For that reason, “[w]e also review” a district court’s

rulings on Article III “standing de novo.” Niemi v. Lasshofer, 770 F.3d 1331, 1344 (10th

Cir. 2014) (citation omitted).

       Further, “[w]e review a Rule 12(b)(6) dismissal de novo.” George v. Urban

Settlement Servs., 833 F.3d 1242, 1247 (10th Cir. 2016) (citation omitted). “A pleading

is required to contain ‘a short and plain statement of the claim showing that the pleader is

entitled to relief.’” SEC v. Shields, 744 F.3d 633, 640 (10th Cir. 2014) (quoting Fed. R.

Civ. P. 8(a)(2)). “We accept as true all well-pleaded factual allegations in the complaint

and view them in the light most favorable to the” plaintiff. Id. (quoting Burnett v. Mortg.

                                              8
Elec. Registration Sys., Inc., 706 F.3d 1231, 1235 (10th Cir. 2013)). We then “determine

whether the plaintiff has provided ‘enough facts to state a claim to relief that is plausible

on its face.’” George, 833 F.3d at 1247 (quoting Hogan v. Winder, 762 F.3d 1096, 1104

(10th Cir. 2014)).

       “In determining the plausibility of a claim, we look to the elements of the

particular cause of action, keeping in mind that the Rule 12(b)(6) standard [does not]

require a plaintiff to ‘set forth a prima facie case for each element.’” Id. (quoting Khalik

v. United Air Lines, 671 F.3d 1188, 1192–93 (10th Cir. 2012)). “The nature and

specificity of the allegations required to state a plausible claim will vary based on

context.” Kan. Penn Gaming, LLC v. Collins, 656 F.3d 1210, 1215 (10th Cir. 2011). But

“mere ‘labels and conclusions’ and ‘a formulaic recitation of the elements of a cause of

action’ will not suffice; a plaintiff must offer specific factual allegations to support each

claim.” Id. at 1214 (quoting Bell Atl. Corp. v. Twombly, 550 U.S. 544, 555 (2007)).

Thus, a “claim is facially plausible if the plaintiff has pled ‘factual content that allows the

court to draw the reasonable inference that the defendant is liable for the misconduct

alleged.’” George, 833 F.3d at 1247 (quoting Hogan, 762 F.3d at 1104, which in turn

quotes Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009)).

       However, “when legal conclusions are involved in the complaint[,] ‘the tenet

that’” we accept the allegations as true “is inapplicable to [those] conclusions.” Shields,

744 F.3d at 640 (second alteration in original) (citation omitted). We likewise “review de

novo a district court’s determination of state law.” Elwell v. Byers, 699 F.3d 1208, 1214

n.4 (10th Cir. 2012) (quoting Salve Regina Coll. v. Russell, 499 U.S. 225, 231 (1991)).

                                               9
Finally, in reviewing orders issued under Rules 12(b)(1) and (6), as in other contexts, we

of course “can affirm a lower court’s ruling on any grounds adequately supported by the

record, even grounds not relied upon by the district court.” Id. at 1213 (citation omitted).

                                 II. Safe Streets Alliance

       In Safe Streets Alliance, the plaintiffs are Michael P. Reilly, Phillis Windy Hope

Reilly, and Safe Streets Alliance (“Safe Streets”). Safe Streets is a “nonprofit

organization devoted to reducing crime and illegal drug dealing,” No. 16-1048, Aplt.

App. at 51,3 “whose members are interested in law enforcement issues, particularly the

enforcement of federal law prohibiting the cultivation, distribution, and possession of

marijuana.” Id. at 52. The Reillys are the only identified members of Safe Streets, and

neither they nor their interest group asserted class or other claims on behalf of any other

Coloradans. We address their RICO claims first and then turn to their preemption claims.

                                     The RICO claims

       The Reillys own a parcel of land in Pueblo County, Colorado that is part “of the

Meadows at Legacy Ranch, a development on the south side of Pickney Road.” Id. at 80.

Safe Streets does not hold any property interest in that land. According to the Reillys,

their land is a “beautiful rolling pasture with sweeping mountain vistas that include views

of Pike’s Peak.” Id. The “Reillys do not live on their land,” and the only known

structures there are “two agricultural buildings” of vague description. Id. However, the

3
 The Reillys and Safe Streets filed two amended complaints. The First Amended
Complaint is the operative pleading with respect to their preemption claims, while the
Second Amended Complaint is relevant to their RICO claims. We refer to them as is
appropriate to our discussion of the specific issue under consideration.

                                             10
Reillys “often visit” the property “on weekends with their children to ride horses, hike,

and visit with friends in the closely-knit neighborhood.” Id.

                                      The allegations

       To the “west and immediately adjacent to the Reillys’ property” is 6480 Pickney

Road, id., the site of a recreational “marijuana grow” operating out of a newly constructed

building located “just a few feet from the Reillys’ property line.” No. 16-1266, Aplt.

App. at 129. The operation of the enterprise and the resultant noxious odors emanating

from it are alleged to have caused harms of two general types.

       First, the Reillys claim that the “publicly disclosed drug conspiracy” itself has

“injured the value of [their] property.” Id. at 131. “People buy lots at the Meadows at

Legacy Ranch because they want to keep horses or build homes in a pleasant residential

area, and the Reillys’ land” allegedly “is less suitable for those uses due to the 6480

Pickney Road marijuana grow.” Id. For example, “the large quantity of drugs at

marijuana grows” purportedly “makes them targets for theft, and a prospective buyer of

the Reillys’ land would reasonably worry that the 6480 Pickney Road marijuana grow

increases crime in the area.” Id.

       Second, the Reillys aver that “[s]ince construction of the facility was completed,

its operation has repeatedly caused a distinctive and unpleasant marijuana smell to waft

onto the Reillys’ property, with the smell strongest on the portion of [their] property that

is closest to [the] marijuana cultivation facility.” Id. at 130. “This noxious odor”

allegedly “makes the Reillys’ property less suitable for recreational and residential

                                             11
purposes, interferes with the Reillys’ use and enjoyment of their property, and diminishes

the property’s value.” Id.

       The Reillys thus contend that the recreational marijuana facility adjacent to their

land has both interfered with their present use and enjoyment of the land and caused a

diminution in its market value—e.g., by subjecting the land to the operation’s noxious

emissions and by commencing that criminal enterprise nearby.

       In Counts I through VI of their Second Amended Complaint, the Reillys brought

civil RICO claims under § 1964(c) against a host of individuals and entities purportedly

affiliated with that neighboring marijuana enterprise. On appeal, the remaining

defendants to those claims are 6480 Pickney, LLC, Alternative Holistic Healing, LLC,

Camp Feel Good, LLC, Jason M. Licata, Joseph R. Licata, and Parker Walton. We refer

to them collectively as the “Marijuana Growers.”

       According to the Reillys, the Marijuana Growers “all understood and agreed that

the property” adjacent to the Reillys’ land “would be used to grow recreational marijuana

for sale at Alternative Holistic Healing’s Black Hawk store, among other places.” Id.

at 119. The Reillys therefore claim that 6480 Pickney, LLC and Alternative Holistic

Healing, LLC are each unlawful enterprises. In addition, the Reillys allege that the

Marijuana Growers “pooled their resources, knowledge, skills, and labor to achieve

through [an] enterprise efficiencies in the cultivation and distribution of marijuana that

none of them could have achieved individually.” Id. at 126. On that basis, the Reillys

claim that the Marijuana Growers also formed a distinct “association-in-fact enterprise for

the purpose of cultivating marijuana at 6480 Pickney Road.” Id.

                                             12
       Consequently, the Reillys allege that the Marijuana Growers are each subject to

civil liability under § 1964(c) for the injuries they have caused to the Reillys’ property by

operating their association-in-fact enterprise, which by definition flouts the CSA, and

therefore violates RICO. See 18 U.S.C. § 1962(c). The Reillys note, for example, that

“[l]easing or maintaining property for the cultivation of marijuana is a crime under” the

CSA “and is racketeering activity” under RICO. No. 16-1266, Aplt. App. at 119.

Likewise, “[d]ealing in marijuana is racketeering activity under RICO,” as is

“conspir[ing] with racketeers by agreeing to assist them” in their unlawful endeavors. Id.

at 101. “And because RICO defines most violations of the CSA as ‘racketeering

activity,’” the Reillys assert, “any business engaged in the commercial cultivation and

sale of recreational marijuana is a criminal enterprise for purposes of” RICO. Id. at 108

(citation omitted). They therefore claim that all those who “conduct or conspire to assist

such enterprises” are subject to “civil liability” under § 1964(c), such that the Marijuana

Growers are liable for harming the Reillys’ property. Id.

       In moving to dismiss, the Marijuana Growers argued that the “speculative injury

to” the Reillys’ “property value” was no “proof of a concrete financial loss,” and was

therefore insufficient “to allege an existing, concrete, financial injury,” which, in their

view, is an element of a § 1964(c) claim. Id. at 25. They also vaguely suggested that the

Reillys had not plausibly alleged that the Marijuana Growers were engaged in a RICO

enterprise. Yet the Marijuana Growers also explicitly conceded that they each “agreed to

grow marijuana for sale” at 6480 Pickney Road, adjacent to the Reillys’ land. Id. at 28.

                                              13
         The district court dismissed these RICO claims with prejudice, concluding that the

Reillys had not pled a plausible injury to their property that was proximately caused by

the Marijuana Growers’ activities in violation of the CSA. The district court recognized

that the Reillys alleged a “noxious order [sic] emanat[es] from the” Marijuana Growers’

adjacent enterprise, which “permit[s] a reasonable inference that the value of their

property is negatively impacted.” Id. at 207. Yet the district court rejected that argument

on the basis that the Reillys had “provide[d] no factual support to quantify or otherwise

substantiate their inchoate concerns as to the diminution in value of their property.” Id.

         The district court underscored the Reillys’ purported failure to plead that their

“land has been appraised for” less “than before the grow operation opened.” Id. And the

district court remarked that the Reillys had “point[ed] to no concrete evidence (as

opposed to mere inchoate fears) that potential purchasers have expressed concern about

living near such a facility, much less declined to buy lots . . . nearby.” Id. Continuing

that theme, the district court determined that the complaint was deficient because the

Reillys failed to “cite to any study or statistics that might demonstrate a causal

relationship between the operation of such businesses and decreased property values”

nearby. Id. According to the district court, the Reillys therefore failed to make the

“showing of damages that are clear and definite” required for “RICO standing,”

counseling dismissal of their “wholly speculative” claims. Id. at 207–08.

         The Reillys timely appealed, which is before us as No. 16-1266.4

4
    Safe Streets is no longer appealing the dismissal of its RICO claims.

                                               14
                                          Analysis

       “RICO is to be read broadly.” Sedima, S.P.R.L. v. Imrex Co., 473 U.S. 479, 497

(1985). It “created a new civil cause of action for ‘[a]ny person injured in his business or

property by reason of a violation of [its] prohibitions.’” RJR Nabisco, Inc. v. European

Cmty., __ U.S. __, 136 S. Ct. 2090, 2096 (2016) (alteration in original) (quoting 18

U.S.C. § 1964(c)). That is, RICO vests a private citizen with substantive rights to avoid

“injur[ies]” to “his business or property” caused by a pattern of racketeering activity, and

it explicitly creates a federal cause of action to vindicate those federal rights. 18 U.S.C.

§ 1964(c). To maintain a cause of action under § 1964(c), a plaintiff must plead and

ultimately prove: (1) that the defendant violated § 1962; (2) that the plaintiff’s business or

property was injured; and (3) that the defendant’s violation is the cause of that injury. Id.;

see RJR, 136 S. Ct. at 2096–97.

       The Reillys assert several theories under which the Marijuana Growers

individually and collectively have violated § 1962, to the injury of the Reillys’ adjacent

land. Here, we need only address one. The Reillys allege that the Marijuana Growers

formed an association-in-fact enterprise that has and will continue to engage in a pattern

of contravening the CSA through the manufacture of marijuana for distribution, an

organizational mission that is a flagrant violation of § 1962(c). The Reillys also claim,

inter alia, that neighboring illegal enterprise directly reduces the present value of their

land by openly operating a criminal initiative; directly causes noxious odors to infiltrate

their property, interfering with their present use and enjoyment of the land; and directly

reduces the property’s present value by burdening it with those emissions. As we will

                                              15
explain, those alleged violations of § 1962(c) and direct injuries are sufficient for the

Reillys to proceed on their RICO claims.

                                  A. Violation of § 1962(c)

       Congress has determined that “[i]t shall be unlawful for any person employed by

or associated with any enterprise engaged in, or the activities of which affect, interstate or

foreign commerce, to conduct or participate, directly or indirectly, in the conduct of such

enterprise’s affairs through a pattern of racketeering activity . . . .” 18 U.S.C. § 1962(c).

Said more succinctly, § 1962(c) “makes it unlawful for a person employed by or

associated with an enterprise to conduct the enterprise’s affairs through a pattern of

racketeering activity.” RJR, 136 S. Ct. at 2097. We have held that a plaintiff asserting a

§ 1964(c) claim for a violation of § 1962(c) “must plausibly allege that” the defendants

“each (1) conducted the affairs (2) of an enterprise (3) through a pattern (4) of

racketeering activity.” George, 833 F.3d at 1248 (citing 18 U.S.C. § 1962(c); Robbins v.

Wilkie, 300 F.3d 1208, 1210 (10th Cir. 2002)).

       The Marijuana Growers forfeited any challenge to several of those elements here

by failing to raise and argue them in the district court. See Richison v. Ernest Grp., Inc.,

634 F.3d 1123, 1127–30 (10th Cir. 2011). We nevertheless address each element because

the factual allegations plausibly demonstrating them significantly overlap. See Boyle v.

United States, 556 U.S. 938, 947 (2009) (explaining that “evidence used to prove” the

elements of a RICO claim may “coalesce” (citation omitted)). We also address the

elements out of order because it better frames our discussion.

                                              16
                                    1. Racketeering activity

       “RICO is founded on the concept of racketeering activity. The statute defines

‘racketeering activity’ to encompass dozens of state and federal offenses, known in RICO

parlance as predicates. These predicates include any act ‘indictable’ under specified

federal statutes,” and among them is “drug-related activity that is ‘punishable’ under

federal law.” RJR, 136 S. Ct. at 2096 (quoting 18 U.S.C. § 1961(1)(D)). As relevant

here, “racketeering activity” includes “dealing in a controlled substance or listed chemical

[]as defined in” the CSA. 18 U.S.C. § 1961(1)(A). Racketeering activity also includes

“any offense involving . . . the felonious manufacture, importation, receiving,

concealment, buying, selling, or otherwise dealing in a controlled substance or listed

chemical,” as defined in the CSA, that is “punishable under any law of the United

States . . . .” Id. § 1961(1)(D).

       It follows, therefore, that operating a marijuana cultivation facility of the type the

Reillys described in their Second Amended Complaint necessarily would involve some

racketeering activity. As just one example, cultivating marijuana for sale—which the

Marijuana Growers admit they agreed to do and they allegedly began and are continuing

to do—is by definition racketeering activity. See id. We conclude the Reillys have

adequately alleged that the Marijuana Growers are each engaged in racketeering activity.

                               2. Association-in-fact enterprise

       Turning to the alleged affiliates of the facility at issue here, “RICO broadly defines

‘enterprise’ as ‘any individual, partnership, corporation, association, or other legal entity,

and any union or group of individuals associated in fact although not a legal entity.’”

                                              17
George, 833 F.3d at 1248 (quoting 18 U.S.C. § 1961(4)). Among other theories, the

Reillys relied on “the latter part of this definition, alleging that” the Marijuana Growers

“formed an association-in-fact enterprise.” Id. (citation omitted). An “association-in-fact

enterprise is ‘a group of persons associated together for a common purpose of engaging in

a course of conduct.’” Boyle, 556 U.S. at 946 (citation omitted). Such an entity “need

not have a hierarchical structure or a ‘chain of command . . . .’” Id. at 948. For it to exist

requires only “a purpose, relationships among those associated with the enterprise, and

longevity sufficient to permit these associates to pursue the enterprise’s purpose.” Id.

at 946.

          Here, the Reillys alleged that for over a year the Marijuana Growers formed “an

association-in-fact enterprise for the purpose of cultivating marijuana at 6480 Pickney

Road and selling it at Alternative Holistic Healing’s Black Hawk store, among other

places.” No. 16-1266, Aplt. App. at 126. To advance their aims, the Marijuana Growers

purportedly “pooled their resources, knowledge, skills, and labor to achieve through th[at]

enterprise efficiencies in the cultivation and distribution of marijuana that none of them

could have achieved individually.” Id. The Reillys’ allegations of purpose, relationship,

and longevity are sufficient for them to proceed on the basis that the Marijuana Growers

together created an association-in-fact enterprise.

          The Marijuana Growers appear to suggest that these allegations are insufficient

because the Reillys also alleged that the corporate defendants were separate, smaller

RICO enterprises. So far as it goes, they are correct that RICO “requires that the ‘person’

conducting the enterprise’s affairs be distinct from the ‘enterprise.’” George, 833 F.3d

                                              18
at 1249 (citing Cedric Kushner Promotions, Ltd. v. King, 533 U.S. 158, 160 (2001)).

That is, “a single person cannot be both the RICO enterprise and the RICO defendant.”

RJR, 136 S. Ct. at 2104 (citing Cedric, 533 U.S. at 162). But that is irrelevant in this

instance.

       Specifically, the Reillys’ alternative enterprise theories do not undermine their

well-supported allegations that the Marijuana Growers are each participating in a distinct,

larger, association-in-fact enterprise. See Boyle, 556 U.S. at 946; George, 833 F.3d

at 1250. The Marijuana Growers allegedly have long worked in concert to achieve

market efficiencies toward their common aim of cultivating, distributing, and selling

marijuana, which undisputedly affects interstate commerce. See RJR, 136 S. Ct. at 2106

(explaining that the enterprise must affect interstate commerce). The Reillys have

adequately alleged that the Marijuana Growers formed an association-in-fact enterprise.

                           3. Conducting the enterprise’s affairs

       We now turn to each of the Marijuana Growers’ conduct in furtherance of their

common goals. To maintain a § 1964(c) claim against any particular defendant, the

Reillys need only to have alleged facts plausibly demonstrating that the defendant

“conduct[ed] or participate[d], directly or indirectly, in the conduct of [the] enterprise’s

affairs.” 18 U.S.C. § 1962(c). “This, in turn, requires a showing that the defendant

‘participate[d] in the operation or management of the enterprise itself.’” George, 833

F.3d at 1251 (quoting Reves v. Ernst & Young, 507 U.S. 170, 185 (1993)). “Under

Reves’ operation or management test, the defendant must have ‘some part in directing’

the enterprise’s affairs.” Id. (quoting Reves, 507 U.S. at 179).

                                              19
       However, “the defendant need not have ‘primary responsibility for the enterprise’s

affairs,’ ‘a formal position in the enterprise,’ or ‘significant control over or within [the]

enterprise’” to be liable under RICO. Id. (citation omitted). The defendant’s actions also

need not have advanced an “economic motive.” Nat’l Org. for Women, Inc. v. Scheidler,

510 U.S. 249, 252 (1994). “Nevertheless, a defendant must do more than simply provide,

through its regular course of business, goods and services that ultimately benefit the

enterprise.” George, 833 F.3d at 1251 (citation omitted). For example, the Reillys at one

time alleged that a contractor violated § 1962 by delivering water to the Marijuana

Growers’ operation. Without more, that would be insufficient to establish that the

contractor was part of the enterprise. See id.

       But “a plaintiff can easily satisfy Reves’ operation and management test by

showing that an enterprise member played some part—even a bit part—in conducting the

enterprise’s affairs.” Id. at 1252. The Marijuana Growers admit that they all “agreed to

grow marijuana for sale” at the facility adjacent to the Reillys’ property, a facility at

which they allegedly have been doing just that. No. 16-1266, Aplt. App. at 28. This

plausibly alleges that the Marijuana Growers each conducted the enterprise’s affairs.

                                           4. Pattern

       For the first time on appeal, the Marijuana Growers suggest that the Reillys failed

to plead sufficient facts to demonstrate that they engaged in a pattern of racketeering

activity. “A predicate offense implicates RICO when it is part of a ‘pattern of

racketeering activity’—a series of related predicates that together demonstrate the

existence or threat of continued criminal activity.” RJR, 136 S. Ct. at 2096–97 (quoting

                                              20
18 U.S.C. § 1961(5), which requires at least two predicate acts committed within ten

years of each other). However, “a RICO victim need not have actual knowledge of

exactly who committed the RICO predicate act resulting in the injury for a civil RICO

claim to accrue.” Robert L. Kroenlein Tr. ex rel. Alden v. Kirchhefer, 764 F.3d 1268,

1278 (10th Cir. 2014). “[T]he threat of continuity may be established by showing that the

predicate acts or offenses are part of an ongoing entity’s regular way of doing business.”

H.J. Inc. v. Nw. Bell Tel. Co., 492 U.S. 229, 249 (1989).

       As discussed, the Marijuana Growers admit that they all agreed to work together to

cultivate marijuana for distribution and sale. The Reillys also allege that the Marijuana

Growers began cultivating marijuana at their neighboring facility. Marijuana is a

controlled substance under the CSA. 21 U.S.C. § 802(16). So the manufacture,

distribution, and sale of that substance is, by definition, racketeering activity under RICO.

18 U.S.C. § 1961(1)(A), (D).

       We need not decide whether the Marijuana Growers’ admitted agreement to take

the related steps necessary to grow marijuana for distribution and sale is itself sufficient

to establish a pattern of predicates that presents a threat of continuing criminal activity.

Rather, we note that the Reillys alleged various actions each of the Marijuana Growers

took to establish and operate the enterprise, an entity that is now purportedly pursuing

those illegal ends. When coupled with the Reillys’ assertion that the Marijuana Growers

began cultivating marijuana at their facility, we conclude these allegations plausibly state

the requisite pattern of predicate acts that present a threat of ongoing criminal activity.

As we will discuss, moreover, this pattern of illegal acts is the direct cause of the Reillys’

                                              21
plausibly alleged injuries to their property.

       5. The Reillys plausibly pled that the Marijuana Growers violated § 1962(c)

       We conclude that the Reillys plausibly pled that the Marijuana Growers violated

§ 1962(c). Having reached that conclusion, we must now determine whether the Reillys

have plausibly alleged an injury to their property caused by that violation, the issue that

the district court thought was dispositive. We therefore need not address the Reillys’

other theories regarding how the Marijuana Growers injured their property by violating

§ 1962, theories the district court also did not specifically discuss. Consequently, the

Reillys’ § 1964(c) claims against the Marijuana Growers premised on other purported

violations of § 1962 remain for adjudication by the district court on remand.

                  B. Proximately caused injuries to the Reillys’ property

       In light of our conclusion that the Reillys plausibly established that the Marijuana

Growers violated § 1962(c), we must now determine whether they plausibly pled

(1) injuries to their property (2) that were caused by those violations. Id. § 1964(c); see

RJR, 136 S. Ct. at 2096. The district court dismissed all of the Reillys’ RICO claims

because, in its view, the Reillys failed to plausibly plead either of these elements.

Specifically, relying on out-of-circuit authorities, the district court determined that hidden

within § 1964(c)’s text is a heightened pleading requirement. According to the district

court, a plaintiff must submit evidence of a “concrete financial loss” (e.g., an appraisal

quantifying the diminution in property value or comparator results of attempts to sell

predating and postdating a RICO violation) to plausibly allege an injury to his property

caused by a defendant’s § 1962 violation. No. 16-1266, Aplt. App. at 206–07 (citation

                                                22
omitted).

       We conclude, however, that neither § 1964(c)’s text nor any ruling by the Supreme

Court or this court establishes the novel statistical evidentiary pleading standard that the

district court applied. In fact, the statute and applicable precedents compel the opposite

conclusion with respect to the Reillys’ allegations that their property has been directly

injured by their neighbors’ odorous and publicly-operating criminal enterprise.

                                         1. Injuries

       Section 1964(c)’s “reference to injury to ‘business or property’ . . . cabin[s]

RICO’s private cause of action to particular kinds of injury—excluding, for example,

personal injuries—[by which] Congress signaled that the civil remedy is not coextensive

with § 1962’s substantive [criminal] prohibitions,” which do not require proof of such

injuries. RJR, 136 S. Ct. at 2108. The Reillys do not claim to have any business-related

rights at issue. So we only need to determine whether the Reillys plausibly alleged

injuries to their property rights. The district court thought not, describing their claims as

based on mere emotional or personal injuries. We disagree.

       Among other things, the Reillys alleged that the noxious odors emanating from the

Marijuana Growers’ criminal enterprise presently interfere with the use and enjoyment of

their land. And they claimed that those odors are a direct result of the Marijuana

Growers’ criminal cultivation of marijuana. They also averred that this ongoing, direct

interference with their property diminishes its present market value—that property that

smells foul is worth less than property that does not. The Reillys further claimed that

their property has declined in value due to the Marijuana Growers’ publicly disclosed

                                             23
operation—in short, that when a crime syndicate openly sets up shop adjacent to one’s

land, it reduces the value of that property. We address the alleged present nuisance and

alleged diminished property value separately, though one stems in part from the other.

                                 a. Odorous nuisance injury

       We have little difficulty concluding that the Reillys plausibly pled an injury to

their property rights caused by the stench that the enterprise’s operations allegedly

produce. “Congress meant to incorporate common-law principles when it adopted

RICO.” Beck v. Prupis, 529 U.S. 494, 504 (2000). In Colorado, “a property owner

whose land is diminished in value by the acquisition and use of adjoining land by a

private party” has a cause of action “in the law of nuisance.” Pub. Serv. Co. of Colo. v.

Van Wyk, 27 P.3d 377, 388 (Colo. 2001) (citation omitted). But Colorado also has long

recognized that invasion of one’s property by noxious odors itself gives rise to a nuisance

claim and is a direct injury to property. See Hobbs v. Smith, 493 P.2d 1352, 1353–54

(Colo. 1972) (explaining that where the facts evidenced “noxious odors” wafting onto the

plaintiffs’ adjoining property, they had “suffered a substantial interference with the use

and enjoyment of their property”); Webster v. Boone, 992 P.2d 1183, 1185–86 (Colo.

App. 1999) (holding that “damages may be recovered” for “nuisance and trespass” to

property, which “generally refers to distress arising out of physical discomfort, irritation,

[and] inconvenience caused by odors, pests, noise, and the like” (emphasis added)).

       Under Colorado law, “the elements of a claim of nuisance are an intentional,

negligent, or unreasonably dangerous activity resulting in the unreasonable and

substantial interference with a plaintiff’s use and enjoyment of her property.” Van Wyk,

                                             24
27 P.3d at 391. Thus, “a plaintiff must establish that the defendant has unreasonably

interfered with the use and enjoyment of her property,” which is “an issue of fact”

determined by “weigh[ing] the gravity of the harm and the utility of the conduct causing

that harm.” Id. (citations omitted). “Generally, to be unreasonable, an interference must

be significant enough that a normal person in the community would find it offensive,

annoying, or inconvenient.” Id. (citations omitted).

       The Marijuana Growers have not pointed us to any authority suggesting that a

landowner’s complaints about a neighbor’s recurrent emissions of foul odors are

conceptually unmoored from the owner’s property rights. Nor do they contend that

Colorado’s recognition of odorous nuisances is any novel departure from the common

law of property rights, which Congress incorporated into § 1964(c). See Beck, 529 U.S.

at 504. They instead suggest that we ought to disbelieve the Reillys’ claims or recast

them as mere emotional injuries, expressions of frustration with either the odors or the

enterprise’s actions.

       The district court adopted that approach. But that was error, inter alia, because the

Reillys’ claims were only at the pleading stage. See George, 833 F.3d at 1247 (requiring

that courts accept all factual allegations as true and draw reasonable inferences in a

plaintiff’s favor at the pleading stage); Shields, 744 F.3d at 640 (same). We conclude that

the Reillys have plausibly pled an injury to their property in the form of a present

interference with their use and enjoyment of that land, an interference that is caused by

the enterprise’s recurring emissions of foul odors.

                                             25
                                 b. Diminished property value

       We now turn to the Reillys’ allegations that the market value of their property has

declined because the Marijuana Growers are publicly operating a criminal enterprise

adjacent to their land, a venture that also emits noxious odors. In Gillmor v. Thomas, 490

F.3d 791 (10th Cir. 2007), we held that landowners could proceed on § 1964(c) claims

against an extortion racket because they had pled plausible injuries to their property

caused by that alleged racket, though we subsequently affirmed summary judgment

against the landowners. Id. at 797–98. As relevant here, the landowners pled that the

racket’s activities “damaged them by reducing the development potential (and thus the

value) of their properties.” Id. at 797. We held that the “allegations [we]re not

conclusory” and were “sufficient” to proceed under § 1964(c). Id. (referring to “RICO

standing” and “jurisdiction”).

       Of course, what we once called “RICO standing” or “statutory standing” we now

properly characterize as the usual pleading-stage inquiry: whether the plaintiff has

plausibly pled a cause of action under RICO. See Lexmark Int’l, Inc. v. Static Control

Components, Inc., __ U.S. __, 134 S. Ct. 1377, 1394 n.4 (2014) (clarifying that “statutory

standing” and “prudential standing” are “misleading” terms because “the absence of a

valid (as opposed to arguable) cause of action does not implicate subject-matter

jurisdiction, i.e., the court’s statutory or constitutional power to adjudicate the case”

(citation omitted)). To answer that question, moreover, we also now adhere to different

rules than those in force when we decided Gillmor. See Twombly, 550 U.S. at 555. But

neither of those sea changes even implicates, let alone undermines, our relevant holding

                                              26
in Gillmor: a plausibly alleged diminution in the present development potential of land is

a property injury under § 1964(c). 490 F.3d at 797. That is also true of our underlying

premise—i.e., that plausibly alleging a reduction in land value is one method of pleading

a property injury under RICO. Id. Colorado’s recognition of that property interest

fortifies our conclusion that RICO incorporates this common view of property rights. See

Van Wyk, 27 P.3d at 388.

       We are therefore puzzled by the district court’s suggestion that Gillmor’s relevant

holding is distinguishable. That is, according to the district court, the Gillmor developers’

plans for their land were—in some unspecified fashion—more concrete than are the

Reillys’ allegations here. But the Reillys aver that today their land is worth less than it

was before, and that this diminution in value occurred because their new neighbors began

their endeavors. Our holding in Gillmor plainly applies here; in fact, it does double duty.

       First, as we have discussed, the Reillys pled ample facts to plausibly establish that

the enterprise’s foul emissions interfere with the use and enjoyment of their property. We

need only draw an eminently reasonable inference to conclude that it is plausible that

activities that interfere with one’s use and enjoyment of property diminish the value of

that property. See George, 833 F.3d at 1247. For example, it is reasonable to think that a

potential buyer would be less inclined to purchase land that is burdened by a

nuisance—such as recurrent foul odors—than she would be to purchase the identical

property if it were unencumbered. See, e.g., Van Wyk, 27 P.3d at 388. Contrary to the

district court’s suggestion, moreover, the Reillys were not required to allege that they had

attempted to sell their land or had appraised it. It remains a commonsense pleading-stage

                                             27
inference that nuisances diminish the value of land, exactly as the Reillys alleged. See

George, 833 F.3d at 1247. Consequently, we conclude that the Reillys plausibly pled that

their property has declined in value due to the recurrent noxious odors emanating from

the Marijuana Growers’ facility. See Gillmor, 490 F.3d at 797.

       Second, the Reillys claim that the open operation of the Marijuana Growers’

criminal enterprise has caused the value of their land to decline, independent of the harms

attending the nuisance. Specifically, they allege that, because a crime syndicate is

publicly violating federal law adjacent to their property, that land is now less valuable.

They suggest, for example, that if they were to attempt to sell their land today, it would be

less attractive to a potential buyer—and is therefore presently worth less—because of the

crimes being openly committed on the adjoining parcel. We conclude this is plausible.

       We cannot countenance the district court’s digression that the Reillys’ claim was

“speculative” and based on mere “inchoate fears” because they did not cite statistics,

appraisals, attempts to sell, or other “concrete evidence” to “quantify” their “concrete

financial loss” with “actual facts.” No. 16-1266, Aplt. App. at 206–08 & n.3 (citation

omitted). Nor are we at liberty to disbelieve the Reillys by ratifying the Marijuana

Growers’ speculation that the value of the Reillys’ land has, perhaps, increased because

of the now-booming market in Colorado for land on which to cultivate marijuana. See

George, 833 F.3d at 1247.

       Moreover, the district court and the Marijuana Growers were mistaken to rely on

Oscar v. University Students Co-operative Association and the cases citing it. 965 F.2d

783 (9th Cir. 1992) (en banc), overruled in part by Diaz v. Gates, 420 F.3d 897 (9th Cir.

                                             28
2005) (en banc). Among the many reasons we refuse to follow Oscar’s unsupported

announcement that a plaintiff must plead a “concrete financial loss” to maintain a RICO

claim for an injury to her property is that those words do not appear in § 1964(c). Id.

at 785. The Supreme Court repeatedly has warned that courts “are not at liberty to

rewrite RICO to reflect their . . . views of good policy.” Bridge v. Phoenix Bond &

Indem. Co., 553 U.S. 639, 660 (2008); Sedima, 473 U.S. at 499–500 (“It is not for the

judiciary to eliminate the private action in situations where Congress has provided it.”).

We also easily distinguish Oscar from the present case on its facts. The Oscar plaintiffs

were renters, whereas the Reillys are landowners, and Oscar itself explicitly disclaims

application to property owners. 965 F.2d at 787 n.2.

       At this stage in the litigation, we conclude that it is reasonable to infer that a

potential buyer would be less inclined to purchase land abutting an openly operating

criminal enterprise than she would be if that adjacent land were empty or occupied by a

lawfully-operating retailer. Based on the Reillys’ assertion that the Marijuana Growers’

operation is anything but clandestine, the Reillys’ land plausibly is worth less now than it

was before those operations began. Therefore, we conclude that the Reillys pled a

plausible diminution in the value of their property caused by the public operation of the

Marijuana Growers’ enterprise. See Gillmor, 490 F.3d at 797.

                           c. The Reillys’ other alleged “injuries”

       In contrast, however, the Reillys claim to have suffered several other injuries that

are not cognizable. For example, they claim to be injured each time they look to the west

and observe the Marijuana Growers’ facility because the structure itself is a constant

                                              29
reminder of the crimes occurring therein. They also speculate that their land might

further diminish in value in the future. But a plaintiff cannot recover for emotional,

personal, or speculative future injuries under § 1964(c). See RJR, 136 S. Ct. at 2108.

       The scope of the Reillys’ presently plausible claims under § 1964(c) is therefore

limited to the alleged injuries the Reillys have suffered or are suffering to their property

rights from the Marijuana Growers’ violations of § 1962. See id. at 2096. We therefore

conclude that the Reillys can, at most, presently recover only for three types of property

injuries that were plausibly pled in their Second Amended Complaint: (1) the interference

with the Reillys’ use and enjoyment of their land caused by the noxious odors emanating

from the Marijuana Growers’ operation; (2) the diminution in the land’s value presently

caused by those odors; and (3) the diminution in the land’s value presently caused by the

existence of that publicly disclosed, ongoing criminal enterprise adjacent to the Reillys’

land. Consequently, we affirm the district court’s order dismissing the Reillys’ RICO

claims premised on any other type of injury.

                                     2. Proximate cause

       We last turn to whether the Reillys plausibly alleged that any of the three classes

of property injuries they sufficiently pled occurred or are occurring “by reason of” the

Marijuana Growers’ purported violations of the CSA, and thus § 1962(c). 18 U.S.C.

§ 1964(c); see RJR, 136 S. Ct. at 2096. Much of the groundwork for our analysis lies in

our discussion of how the Reillys’ property plausibly was injured in each of those three

ways. We now focus more closely on causation—the nexus between act and injury.

       “[T]o establish the requisite element of causation” to maintain a § 1964(c) claim, a

                                              30
plaintiff must plausibly plead “that the defendant’s violation not only was a but for cause

of his injury, but was the proximate cause as well . . . .” Bridge, 553 U.S. at 654 (quoting

Holmes v. Sec. Inv’r Prot. Corp., 503 U.S. 258, 268 (1992)). “Proximate cause,” Bridge

explains, “is a flexible concept that does not lend itself to ‘a black-letter rule that will

dictate the result in every case.’” Id. (citation omitted). It is a way of “‘label[ing]

generically the judicial tools used to limit a person’s responsibility for the consequences

of that person’s own acts,’ with a particular emphasis on the ‘demand for some direct

relation between the injury asserted and the injurious conduct alleged.’” Id. (first quoting

Holmes, 503 U.S. at 268; then citing Anza v. Ideal Steel Supply Corp., 547 U.S. 451, 461

(2006)).

       In turn, “[w]hen a court evaluates a RICO claim for proximate causation, the

central question it must ask is whether the alleged violation led directly to the plaintiff’s

injuries.” Anza, 547 U.S. at 461. Contrariwise, Anza explains, “[t]here is no need to

broaden the universe of actionable harms to permit RICO suits by parties who have been

injured only indirectly.” Id. at 460. Whether the Reillys alleged any direct or only

indirect injuries attributable to the Marijuana Growers’ violations of § 1962 was a point

of some dispute before the district court. It is easily resolved in the Reillys’ favor by the

Supreme Court’s cases emphasizing the distinctions between direct and indirect injuries.

                                a. Direct vs. indirect injuries

       In Holmes, the Court confronted RICO claims premised on the alleged

manipulation of stocks. 503 U.S. at 261. The plaintiff was an investor protection

corporation claiming to have subrogated rights to sue on behalf of the customers of

                                               31
injured broker-dealers. Id. at 270–71. Discussing the proximate cause element, the Court

held that “the link [was] too remote between the stock manipulation alleged and the

customers’ harm, being purely contingent on the harm suffered by the broker-dealers,” to

sustain a § 1964(c) claim. Id. at 271. Thus, § 1964(c)’s bar to recovery for “indirect”

injuries sometimes is shorthand for a well-recognized principle of proximate causation:

“[A] plaintiff who complain[s] of harm flowing merely from the misfortunes visited upon

a third person by the defendant’s acts [i]s generally said to stand at too remote a distance

to recover.” Id. at 268–69 (citation omitted).

       In Anza, the Court recognized two additional but related iterations of § 1964(c)’s

bar to recovering for indirect injuries. 547 U.S. at 458–59. The defendants in Anza

allegedly defrauded New York’s tax authority by committing mail and wire fraud, in

violation of § 1962(c). Id. at 457–59. However, the plaintiff sought to recover for its lost

sales, the result of the defendants’ distinct scheme of artificially lowering prices by not

charging customers required sales taxes. Id. at 458. The plaintiff’s RICO claims first

failed to meet the proximate cause element because “[t]he cause of [the] asserted harms”

was “a set of actions (offering lower prices) entirely distinct from the alleged RICO

violation (defrauding the State).” Id. “[A] second discontinuity between the RICO

violation and the asserted injury” was that the plaintiff’s “lost sales could have resulted

from factors other than [the] alleged acts of fraud.” Id. at 459. The Court explained:

“Businesses lose and gain customers for many reasons, and it would” have “require[d] a

complex assessment to establish what portion of” the plaintiff’s “lost sales were the

product of” the defendant’s “decreased prices.” Id.

                                             32
       On the other hand, in Bridge, the Court considered whether “a plaintiff asserting a

RICO claim predicated on mail fraud must plead and prove that it relied on the

defendant’s alleged misrepresentations.” 553 U.S. at 641–42. The Court held that the

plaintiffs could proceed on their § 1964(c) claims premised on direct injuries from the

“los[s of] valuable liens they otherwise would have been awarded,” even though other

direct victims of the criminal scheme also could have sued. Id. at 649–50. The Court

relatedly held that a plaintiff is not required to plead that he is a victim of the defendant’s

underlying crime (e.g., that he relied on the fraudulent mailings) to establish a direct

injury. Id. Rather, a plaintiff may establish proximate causation by plausibly pleading

that his business or property has been directly injured as a result of the defendant’s § 1962

violation. Id. The Court also refused to foreclose a plaintiff’s RICO claim even where

“traditional state-law remedies” are available, explaining that courts cannot “adopt

narrowing constructions of RICO in order to make it conform to a preconceived notion of

what Congress intended to proscribe.” Id. at 659–60.

  b. The Reillys’ injuries plausibly were proximately caused by the § 1962(c) violations

       None of the Supreme Court’s formulations of the term “indirect injury” bears any

resemblance to the Reillys’ three plausibly alleged injuries caused by the Marijuana

Growers’ violations of § 1962(c). The Reillys are suing to recover for injuries to their

own land, not harms to third parties. See Holmes, 503 U.S. at 268–69. No intermediary

breaks the causal chain, for example, between the enterprise’s foul emissions and the

Reillys’ nuisance injury. See id. All three plausibly alleged injuries—the nuisance, the

resultant decline in property value, and the further decline in property value stemming

                                              33
from the enterprise’s open pursuit of its goals—were also caused by the Marijuana

Growers’ criminal cultivation of marijuana itself. See Anza, 547 U.S. at 458.

       Further, no complex, external factors are at play, as the enterprise is the direct

source of all of the alleged injuries to the Reillys’ land. See id. at 459. For example, the

Reillys have plausibly alleged that the Marijuana Growers’ violations of § 1962(c)

distinctly affect the land’s value, including how prospective buyers would evaluate it

today. Moreover, contrary to the district court and the Marijuana Growers’ suggestions,

whether the Reillys might have pursued separate nuisance claims is irrelevant to whether

their § 1964(c) claims are viable. See Bridge, 553 U.S. at 659–60. It is also of no

moment whether the Reillys are victims of the alleged § 1962 violations. See id. at 650.

       Rather, it is sufficient that the property injuries that the Reillys allege are direct

byproducts of the location and manner in which the Marijuana Growers are conducting

their operations that purportedly violate the CSA. Therefore, we conclude that the Reillys

have plausibly alleged that the Marijuana Growers’ violations of the CSA, and thus

§ 1962(c), proximately caused each of those three property injuries to the Reillys’ land.

Consequently, we conclude that the Reillys have plausibly stated § 1964(c) claims against

each of the Marijuana Growers for those three types of injuries.

                                         Conclusions

       In No. 16-1266, we reverse the district court’s order and its judgment dismissing

the Reillys’ § 1964(c) claims against the Marijuana Growers, as pled in Counts I through

VI of their Second Amended Complaint. We remand Safe Streets Alliance to the district

court for further proceedings on the Reillys’ three plausibly alleged property injuries

                                              34
against each of the Marijuana Growers for conducting their association-in-fact enterprise

in a manner that violates the CSA, and thus § 1962(c).

       We also remand to the district court the balance of the Reillys’ RICO claims

against the Marijuana Growers premised on other alleged violations of § 1962, but only to

the extent that such violations are alleged to have caused one or more of those three types

of injuries. Consequently, we do not decide what remedies are or are not available under

RICO. We affirm the district court’s order and its judgment dismissing the RICO claims

in all other respects.

       Finally, we emphasize that our narrow holdings today do no more than apply the

heavily fact-dependent standard Congress enumerated in § 1964(c) to the allegations in

this case. We are not suggesting that every private citizen purportedly aggrieved by

another person, a group, or an enterprise that is manufacturing, distributing, selling, or

using marijuana may pursue a claim under RICO. Nor are we implying that every person

tangentially injured in his business or property by such activities has a viable RICO

claim. Rather, we hold only that the Reillys alleged sufficient facts to plausibly establish

the requisite elements of their claims against the Marijuana Growers here. The Reillys

therefore must be permitted to attempt to prove their RICO claims.

                                  The preemption claims

       We now turn to the Reillys and Safe Streets’ asserted injuries and purported causes

of action “in equity” against Colorado and Pueblo County for a declaratory judgment

abrogating Amendment 64 as preempted by the CSA, and for concomitant injunctive

relief blocking statewide enforcement of that Amendment. Careful parsing is in order:

                                             35
These private plaintiffs allege property injuries and assert (a) causes of action

(b) invoking our equitable powers (c) to grant injunctive relief (d) against Colorado and

Pueblo County, (e) in response to the State and County’s purported violations of federal

law, and (f) by operation of the Supremacy Clause and the CSA’s preemption provision,

21 U.S.C. § 903. Conspicuously absent from these alleged causes of action are any

jurisprudential bases for them.

       We first describe those putative causes of action, under which these plaintiffs

neither claim that the State or the County is regulating their conduct, nor assert that the

Supremacy Clause or the CSA explicitly recognizes their property rights or, in fact, grants

them any substantive rights. We then recount Supreme Court precedents explaining

precisely why, in such circumstances, the conceded absence of any private substantive

right in the CSA forecloses federal relief based on alleged violations of the CSA, in

equity or otherwise.5

5
 The Concurrence states that we “declare[] that even if state and local law is preempted
by the” CSA, “the plaintiffs cannot seek injunctive relief against those laws under the
federal courts’ equity powers because neither the CSA nor any other federal law bestows
on them a substantive private right.” Concurrence at 1. That is not the full import of our
ruling. As we will explain, the Supreme Court has repeatedly recognized that the
Constitution itself forbids private plaintiffs from enforcing federal statutes in which they
have no substantive rights. See, e.g., Va. Office for Prot. & Advocacy v. Stewart, 563
U.S. 247, 260–61 & n.8 (2011). The Concurrence could also be understood to suggest
that we conclude this is the only avenue to obtain relief under a federal court’s equitable
powers. As we will also discuss, however, preemption-based affirmative defenses to
enforcement actions exist. See, e.g., Armstrong v. Exceptional Child Ctr., Inc., __ U.S.
__, 135 S. Ct. 1378, 1384 (2015) (noting these defenses). But, like Armstrong, we devote
comparatively little of our analysis to such defenses because, we easily conclude, they are
not at issue here—e.g., Colorado is not forcing the Reillys to grow or distribute
marijuana, and they have not expressed any fear that the State will do so. See infra
                                                                                    (continued...)

                                             36
                                       The allegations

       The Reillys and Safe Streets allege that Colorado and its municipalities have

“facilitated the emergence of a billion dollar industry built upon the brazen commission

of federal drug crimes.” No. 16-1048, Aplt. App. at 66. The Reillys and Safe Streets thus

seek “to vindicate their” purported “federal rights under . . . the Supremacy Clause.” Id.

at 51. To that end, in Counts VII and VIII of their First Amended Complaint, the Reillys

and Safe Streets assert that Amendment 64 conflicts with and is therefore preempted by

the CSA, pursuant to the Supremacy Clause and § 903. They aver that “[f]ederal courts

sitting in equity have the power to set aside actions of state [and local] officials that are

preempted under the Supremacy Clause,” and under § 903 as well. Id. at 96.

       Specifically, in the first of their “preemption counts,” the Reillys and Safe Streets

seek “federal preemption of” Colorado’s “marijuana licensing” regime. Id. at 95

(emphasis and capitalization omitted). They named as defendants the following State

officers in their official capacities: John W. Hickenlooper, Jr., the Governor of Colorado;

Barbara J. Brohl, the Executive Director of the Colorado Department of Revenue; and W.

Lewis Koski, the Director of the Colorado Marijuana Enforcement Division (MED).

James Burack succeeded Koski in office and was “automatically substituted as a party.”

Fed. R. App. P. 43(c)(2). We refer to these defendants collectively as “Colorado.”

       In their second “preemption count[],” the Reillys and Safe Streets raised

(...continued)
note 19. Our discussion should not be understood to suggest that we have failed to
account for this entirely separate species of claims.

                                              37
substantively identical claims with respect to Pueblo County, Colorado’s “local marijuana

licensing” regime. No. 16-1048, Aplt. App. at 97 (emphasis and capitalization omitted).

They named as defendants to those claims the Board of County Commissioners of the

County of Pueblo and the Pueblo County Liquor and Marijuana Licensing Board. We

refer to these defendants collectively as “Pueblo County.”

       In support of those claims, Safe Streets referred to “injuries caused by the

operation[] of the Colorado-licensed marijuana industry.” Id. at 52. However, it did not

allege any particular injury that it or its other, unidentified members have suffered from

Colorado’s “efforts to license and promote the commercial marijuana industry.” Id. at 82.

For example, although Safe Streets claimed that the “MED’s decision to license [a]

recreational marijuana infused products manufacturer” in Denver “has substantially

damaged the value of surrounding properties,” it did not assert that its members’

properties “near” that facility have been damaged. Id. at 82–83.

       In contrast, the Reillys alleged that Colorado and Pueblo County caused them to

suffer specific, but discrete, injuries. In particular, the Reillys alleged that the Marijuana

Growers “applied for both state and local licenses to cultivate marijuana at 6480 Pickney

Road.” Id. at 71. “On October 1, 2014, MED granted” the Marijuana Growers “a state

license, conditioned on [them] also obtaining a local license,” which they later were

issued by Pueblo County. Id. at 71–72. The Reillys thus claim that Colorado and Pueblo

County’s “decisions to license those operations injure the Reillys’ property.” Id. at 80

(emphasis and some capitalization omitted).

                                              38
       More specifically, the Reillys contend that the Marijuana Growers “could not have

located their marijuana grow operation at 6480 Pickney Road if they had not received

authorization from” Colorado and Pueblo County “to do so.” Id. at 82. This is

exemplified, the Reillys aver, by the fact that the Marijuana Growers “did not begin

construction on the facilities at 6480 Pickney Road until the State” and the County issued

the licenses that “authorized them to grow marijuana at that location.” Id. “Thus,” the

Reillys claim that Colorado and Pueblo County “also caused the[m] to suffer injuries” to

their property. Id.

       For example, they claim that the “MED’s licenses . . . affirmatively assist and

promote the commercial cultivation and distribution of recreational marijuana by

functioning as a state endorsement of licensed businesses and employees.” Id. at 96–97.

In turn, those “endorsement[s]” purportedly “assist[] potential recreational marijuana

investors and customers by assuring them that [the] licensees have been investigated and

approved by the State” and the County. Id. at 97. The Reillys and Safe Streets also claim

that the United States has “adopted a policy of not bringing criminal charges against those

who commit marijuana-related drug crimes in a manner that is consistent with state and

local law.” Id. at 73. Thus, the Reillys and Safe Streets suggest that the licenses

Colorado and Pueblo County issued to the Marijuana Growers were, and are, “essential

to” that enterprise’s “ability to openly violate the federal drug laws through large-scale

cultivation and storefront sale of recreational marijuana.” Id.

       The Reillys and Safe Streets also claim that Colorado and Pueblo County’s

“issuance of recreational marijuana licenses directly conflicts with the CSA,” such that

                                             39
the “licensing regime is preempted by federal law and cannot stand.” Id. at 97. Absent

from the Reillys and Safe Streets’ pleadings, however, are any facts purporting to link

Colorado’s statewide licensing regime, its effects, or the benefits Colorado allegedly

accrues from it to any specifically alleged injury to the Reillys, their land, Safe Streets, or

its unidentified members. This is also true of Pueblo County’s countywide regime.

       Nevertheless, the Reillys and Safe Streets demand sweeping relief. They seek an

“order” directing Colorado and Pueblo County “to withdraw” all of “the recreational

marijuana licenses” they have “issued so far and not to issue any additional such licenses

in the future.” Id. at 51–52. In similar fashion, the Reillys and Safe Streets request a

declaratory judgment that Colorado and Pueblo County’s “issuance of marijuana business

and occupational licenses is preempted by federal law.” Id. at 99. Accordingly, they also

request an order “[v]acating” all of the “marijuana business and occupational licenses

issued by” the State and the County, and an order “enjoining” Colorado and Pueblo

County “from issuing additional” licenses. Id.

       Finally, they demand an even more comprehensive declaratory judgment “that

those portions of the Colorado Constitution and the [Colorado] Retail Marijuana Code

that purport to authorize or facilitate violations of the federal drug laws are preempted by

federal law.” Id. But we apparently are to discern for ourselves precisely which

offending words are to be stricken from, inter alia, the Colorado Constitution. For the

Reillys and Safe Streets did not plead—and they have never identified—precisely which

provisions of the Colorado Constitution, the Colorado Retail Marijuana Code, the Pueblo

                                              40
County Code, or those alluded-to regulations conflict with specific provisions of the CSA

and are therefore preempted by operation of § 903 and the Supremacy Clause.

       In any event, at Colorado and Pueblo County’s request, the district court severed

the preemption claims from the RICO claims. Colorado and Pueblo County then moved

to dismiss the preemption claims. The Reillys and Safe Streets’ response advanced the

same novel concepts that we will discuss below. It suffices here to make only two points.

       First, the Reillys and Safe Streets confirmed that they were seeking “a decision

invalidating the State’s [and the County’s] marijuana licensing and regulatory laws” in

their entirety, untethered to any specifically alleged injuries. Id. at 182.

       Second, relatedly, they did not directly address Colorado and Pueblo County’s

argument that they cannot enforce the CSA because that federal statute does not grant

private citizens any relevant substantive rights. Indeed, the Reillys and Safe Streets did

not contend that § 903 or any other provision of the CSA, in fact, vests private citizens

with any relevant substantive rights. Nor did they purport to identify any substantive

rights recognized in the Constitution or established by any federal statute that serve as the

foundation for their alleged causes of action in equity for sweeping injunctive relief.

Rather, according to the Reillys and Safe Streets, they are simply “invoking [the Article

III courts’] equitable authority to enjoin actions by state officers that are preempted by

the” CSA “and thus violate the Supremacy Clause . . . .” Id. at 149.

       The district court was unpersuaded. It determined—for reasons similar to but not

the same as those undergirding our conclusions—that the Reillys and Safe Streets had not

alleged viable causes of action, and it dismissed their preemption claims. The Reillys and

                                              41
Safe Streets timely appealed, which is before us as No. 16-1048.

                                           Analysis

       The Reillys and Safe Streets assert that they do not need any constitutional or

federal substantive rights to be entitled to remedy a State’s, a municipality’s, or any

government officer’s violation of federal law. Rather, they claim to be able to enforce the

CSA’s preemptive effects “in equity” so long as they have been injured—in any way—by

official conduct that also violates a federal statute. Under their theory of equitably

derived federal substantive rights, all such injuries give rise to causes of action to enforce

federal law against any government officer, and for plenary injunctive relief.

       More specifically, the Reillys and Safe Streets do not assert that their putative

causes of action are based on any substantive rights created or even protected by the

Constitution, § 903, any other provision of the CSA, or any federal statute.6 They instead

hypothesize that a private plaintiff may enforce any provision of any federal statute “in

equity” whenever: (a) a State, a municipality, or one of their officers violates that statute;

and (b) that private citizen suffers any alleged injury as a result.

       For example, the Reillys claim that their property has been injured by Colorado

6
 If somewhere lurking in the record on appeal or the briefs is any reference to a relevant
substantive right that Congress bestowed on private citizens or incorporated by reference
in the CSA, we have not found it. In any event, the failure to adequately develop such an
argument in the district court forfeited it, and it is waived, moreover, because no such
argument was raised and developed on appeal. See Holmes v. Colo. Coal. for Homeless
Long Term Disability Plan, 762 F.3d 1195, 1199 (10th Cir. 2014) (declining to consider
arguments on appeal that were inadequately briefed); Murrell v. Shalala, 43 F.3d 1388,
1390 n.2 (10th Cir. 1994) (declining to consider “a few scattered statements” and
“perfunctory” arguments that failed to develop an issue).

                                              42
and Pueblo County’s activities. But they do not assert that the CSA refers to a private

citizen’s real property rights, let alone protects those rights.7 The Reillys similarly claim

to have suffered grievous emotional injuries at the State’s and the County’s hands—when

they look upon the Marijuana Growers’ government-licensed facility, they are reminded

that criminal activity is afoot. But the Reillys do not direct us to the provision of the CSA

aimed at safeguarding a citizen’s psyche. This is no oversight; there is none.

Nevertheless, the Reillys claim to be able to enforce § 903 (and, through it, the entire

CSA) on a statewide basis.

       Their remarkable vision of federal equitable relief in the absence of federal

substantive rights is, apparently, premised on the notion that free-floating causes of action

in equity exist unless “Congress has restricted the courts’ preexisting equitable authority

to enjoin violations of federal law.” No. 16-1048, Aplt. Reply Br. at 5 n.1 (emphasis

omitted). According to the Reillys and Safe Streets, “equity” is “a standalone source of

legal rights,” the “origin of a host of substantive rights not recognized at common law,”

by which they argue that equity itself creates a substantive right permitting them to

enforce the entire CSA against Colorado and Pueblo County. Id. at 18 (citations omitted).

Employing a clever turn of phrase, they thus “seek to enforce the substantive federal rule

that States may not authorize, promote, or facilitate violations of the federal drug laws,”

7
 Of course, we are aware that the CSA bestows specific substantive rights on particular
classes of private citizens for certain types of activities. But those rights have not been
invoked in these cases, and, in any event, none of them are even arguably relevant here.
E.g., 21 U.S.C. § 830(c)(4) (“Any person who is aggrieved by a disclosure of” certain
prescription records “may bring a civil action against the violator for appropriate relief.”).

                                              43
including the CSA. Id. at 6–7 (emphasis added). The Reillys and Safe Streets can do

this, they claim, because “nothing in the CSA suggests that Congress intended for this

rule to be enforced by some means other than private suits in equity against state

officers.” Id. at 7. So we are asked to pay no mind to Article II.

       The Reillys and Safe Streets next inform us that no principle holds “a plaintiff may

not sue state officers who are injuring him by implementing a policy that conflicts with

federal law unless a federal statute confers ‘enforceable legal rights’ or the suit is brought

in anticipation of a state enforcement action.” Id. at 14–15. The heart of their argument

is that there is no “rationale for limiting suits in equity” in this way. Id. at 17. That is,

“other types of injuries, such as those [they] allege here”—i.e., not based on any federal

substantive rights—“should be an equally valid basis for invoking the federal courts’

equitable powers.” Id. We are thus urged to ignore Article I.

       Finally, the Reillys and Safe Streets hypothesize that once a private citizen has

been injured by such an act, she or he has an equitable cause of action to enjoin the

State’s or its officers’ conduct to the full extent of the statutory violation, without regard

to the scope of the plaintiff’s alleged injuries. For example, the Reillys request that we

issue a declaratory judgment and an injunction barring enforcement of Amendment 64

statewide, inter alia, by invalidating not just the Marijuana Growers’ licenses, but all such

licenses. The Reillys seek this far-flung relief even though their only alleged injuries

concern property damage and emotional harms. Having cavalierly dispensed with

Articles I and II, they at last encourage us to cast aside Article III.

                                               44
                               A. Subject matter jurisdiction

       These circumstances—plaintiffs purportedly bringing causes of action for federal

“relief,” but failing to invoke federal rights—raise a threshold question whether we have

subject matter jurisdiction over Safe Streets Alliance. See United States v. Ruiz, 536 U.S.

622, 628 (2002); Shepherd v. Holder, 678 F.3d 1171, 1180 (10th Cir. 2012). We must

decide that issue, which we can do because we “always ha[ve] jurisdiction to determine

[our] own jurisdiction.” Ruiz, 536 U.S. at 628.

       The Reillys pled well-defined federal causes of action to vindicate federal

substantive rights Congress enumerated in RICO. “[W]hen federal law creates a private

right of action and furnishes the substantive rules of decision, the claim arises under

federal law, and district courts possess federal-question jurisdiction under § 1331.” Mims

v. Arrow Fin. Servs., LLC, 565 U.S. 368, 378–79 (2012); see 28 U.S.C. § 1331.

Regardless of the nature of the Reillys and Safe Streets’ preemption claims, therefore, the

district court necessarily had subject matter jurisdiction over those claims at the time the

suit commenced, adjudicative power it retained after the preemption claims were severed.

See 28 U.S.C. § 1367(a).

       To the extent that the disparate nature of these claims vis-à-vis the RICO claims

raises any doubts about this, cf. Fed. R. Civ. P. 20(a)(1), we conclude that the district

court had an independent basis of subject matter jurisdiction over the preemption claims

under 28 U.S.C. § 1331 for at least two distinct, but related, reasons.

       First, whether the Reillys and Safe Streets’ preemption claims are viable turns, as a

threshold merits matter, on whether (as alleged) the federal courts possess the inherent

                                             45
power in equity to countenance private enforcement of a federal statute under which those

plaintiffs admittedly possess no federal substantive rights that they are seeking to

vindicate. This necessarily raises a question of federal common law: Do the Article III

courts’ equitable powers include authority to grant injunctive relief of this type? It is

axiomatic that the district court had jurisdiction under § 1331 to answer this question.

Nat’l Farmers Union Ins. Cos. v. Crow Tribe of Indians, 471 U.S. 845, 850 (1985) (“It is

well settled that [§ 1331’s] statutory grant of ‘jurisdiction will support claims founded

upon federal common law as well as those of a statutory origin.’ Federal common law as

articulated in rules that are fashioned by court decisions are ‘laws’ as that term is used in

§ 1331.” (footnotes omitted) (quoting Illinois v. City of Milwaukee, 406 U.S. 91, 100

(1972))).

       Second, and only with that question answered, the Reillys and Safe Streets’

attempts to privately enforce the CSA in this manner raise, at minimum, “substantial

question[s] of federal law” on the merits that were sufficient for the district court to have

exercised jurisdiction over the preemption claims in their entirety under § 1331.

Franchise Tax Bd. v. Constr. Laborers Vacation Tr., 463 U.S. 1, 13 (1983); see Bolivarian

Rep. of Venez. v. Helmerich & Payne Int’l Drilling Co., __ U.S. __, 137 S. Ct. 1312,

1322 (2017) (“[T]his Court [has] held that the ‘arising under’ statute confers jurisdiction

if a plaintiff can make a nonfrivolous argument that a federal law provides the relief he

seeks—even if, in fact, it does not.”); Gunn, 133 S. Ct. at 1065 (“[F]ederal jurisdiction

over a state law claim will lie if a federal issue is: (1) necessarily raised, (2) actually

disputed, (3) substantial, and (4) capable of resolution in federal court without disrupting

                                               46
the federal-state balance approved by Congress.”); Empire Healthchoice Assurance, Inc.

v. McVeigh, 547 U.S. 677, 697 (2006); Grable & Sons Metal Prods., Inc. v. Darue Eng’g

& Mfg., 545 U.S. 308, 314 (2005); see also Steel Co. v. Citizens for a Better Env’t, 523

U.S. 83, 89 (1998) (“Dismissal for lack of subject-matter jurisdiction because of the

inadequacy of the federal claim is proper only when the claim is ‘so insubstantial,

implausible, foreclosed by prior decisions of [the Supreme] Court, or otherwise

completely devoid of merit as not to involve a federal controversy.’” (citation omitted)).

       It follows, therefore, that in No. 16-1048 we have appellate jurisdiction over the

preemption claims in Safe Streets Alliance. 28 U.S.C. § 1291; see, e.g., Lexmark, 134 S.

Ct. at 1387 n.4 (“[T]he absence of a valid (as opposed to arguable) cause of action does

not implicate subject-matter jurisdiction, i.e., the court’s statutory or constitutional power

to adjudicate the case.” (quoting Verizon Md. Inc. v. Pub. Serv. Comm’n of Md., 535

U.S. 635, 642–43 (2002))).

                                    B. Background issues

       We pause to note three related issues that frame our discussion.

       First, none of the claims before us today are asserted on behalf of others similarly

situated or on an alleged class-wide basis. Recall, for example, that the Reillys are the

only identified members of Safe Streets.

       Second, no facial or as-applied challenge to Amendment 64 was asserted in the

complaints, argued to the district court, or presented to us. Cf. United States v. Stevens,

559 U.S. 460, 472–75 (2010); United States v. Salerno, 481 U.S. 739, 745 (1987).

       Finally, the Reillys and Safe Streets argue that they must be able to enforce § 903

                                              47
because if they cannot, then neither can the Attorney General. That follows, they claim,

because just as private citizens are not mentioned in § 903, neither is the Attorney

General. And they surmise that if private citizens lack the power to enforce § 903, that

means the United States also must not be able to enforce federal law. We will highlight

only two of the most glaring reasons why that notion is specious.

       For one, the “assumption that if” the Reillys or Safe Streets “ha[d] no standing to

sue, no one would have standing, [would] not [be] a reason to find standing.” Clapper v.

Amnesty Int’l USA, __ U.S. __, 133 S. Ct. 1138, 1154 (2013). For another, the Reillys

and Safe Streets are obviously incorrect that the Attorney General’s authority to enforce

§ 903 is related in any way to a private citizen’s inability to do so. See United States v.

Armstrong, 517 U.S. 456, 464 (1996) (“The Attorney General and United States

Attorneys ‘retain broad discretion’ to enforce the Nation’s criminal laws.” (citations

omitted)). The Supreme “Court has implied causes of action in favor of the United States

in cases where the statute creates a duty in favor of the public at large,” as does the CSA.

Cannon v. Univ. of Chicago, 441 U.S. 677, 690 n.13 (1979) (citation omitted).

       The Supreme Court has reaffirmed time and again that the United States is

empowered to enforce the supremacy of federal law against preempted State action, and

that it may obtain an injunction to that effect. See, e.g., Arizona v. United States, __ U.S.

__, 132 S. Ct. 2492, 2497 (2012); 21 U.S.C. § 882(a) (authorizing injunctions).

Regardless of the outcome of any of the claims here, therefore, the Attorney General

remains empowered to enforce the CSA to the extent Congress so authorized. See

Gonzales v. Oregon, 546 U.S. 243, 258 (2006). Of course, the Supreme Court also “has

                                             48
recognized on several occasions over many years that an agency’s decision not to

prosecute or enforce, whether through civil or criminal process, is a decision generally

committed to an agency’s absolute discretion.” Heckler v. Chaney, 470 U.S. 821, 831

(1985). But where the Attorney General chooses to exercise that delegated authority, her

or his power plainly is not coextensive with that possessed by a private citizen. See

United States v. Oakland Cannabis Buyers’ Coop., 532 U.S. 483 (2001). Our analysis

does not implicate the Attorney General’s authority over the CSA.

C. Private citizens without injuries to rights enumerated in the CSA cannot enforce § 903

       The Reillys and Safe Streets rely on Armstrong v. Exceptional Child Center, Inc.,

__ U.S. __, 135 S. Ct. 1378 (2015), and its progenitors for the contention that Congress

has not foreclosed equitable relief to remedy Colorado and Pueblo County’s purported

violations of the CSA. See id. at 1385–87 (discussing that issue). They argue that they

can maintain causes of action in equity to enjoin Colorado and Pueblo County’s

enforcement of Amendment 64. The district court indulged that inquiry. But the Reillys

and Safe Streets critically misread Armstrong and relatedly either ignore or, at best,

misunderstand the threshold, dispositive issue here.8

8
 As described in our analysis of the Reillys’ RICO claims, they have alleged redressable
injuries purportedly caused in part by Colorado and Pueblo County’s recreational
marijuana licensing regime. This gives them Article III standing to assert at least some of
their claims seeking to remedy their injuries by enforcing the CSA, in turn requiring us to
reach whether any such claim is viable. See Spokeo, Inc. v. Robins, __ U.S. __, 136 S.
Ct. 1540, 1547 (2016); Lexmark, 134 S. Ct. at 1386, 1394. For the same reasons, we
need not separately address Safe Streets’ Article III standing to raise substantively
identical putative causes of action. See Horne v. Flores, 557 U.S. 433, 446–47 (2009)
(“Because the superintendent clearly has standing to challenge the lower courts’
                                                                                (continued...)

                                             49
       In Armstrong, the Supreme Court conducted a familiar three-step analysis of

whether the plaintiffs’ claims were viable. The Court: (1) discerned what alleged

substantive rights the plaintiffs were seeking to vindicate; (2) decided what putative

causes of action the plaintiffs were raising based on those rights; and (3) determined

which, if any, of those causes of action were viable, and specifically with respect to the

equitable relief requested. See id. at 1382–87; Davis v. Passman, 442 U.S. 228, 239–41

& n.18 (1979) (detailing that order of battle).

       At the first step, the Court succinctly remarked that the plaintiffs were “providers

of habilitation services to persons covered by Idaho’s Medicaid plan” who “claim[ed] that

Idaho violates § 30(A)” of Medicaid “by reimbursing [them] at rates lower than § 30(A)

permits.” Armstrong, 135 S. Ct. at 1382. That is, the providers brought causes of action

in equity under § 30(A), by which they sought to enjoin Idaho and its officers to fully

remunerate them for their services. Id. They thus attempted to vindicate their averred

federal property rights to those funds, rights allegedly bestowed on them by § 30(A).9 Id.

decisions, we need not consider whether the Legislators also have standing to do so.”);
Vill. of Arlington Heights v. Metro. Hous. Dev. Corp., 429 U.S. 252, 264 & n.9 (1977)
(“[W]e have at least one individual plaintiff who has demonstrated standing . . . .
Because of the presence of this plaintiff, we need not consider whether the other
individual and corporate plaintiffs have standing to maintain the suit.”).
9
 The Concurrence quotes this statement and responds that “no language in” Armstrong
“stat[es] that the Court should ‘first’ (or ever, when examining the federal courts’ equity
power) concern itself with whether the party seeking injunctive relief alleged any federal
substantive right.” Concurrence at 6. According to the Concurrence, Armstrong did not
“ever say that the providers possessed or even asserted such a right.” Id. These are two
separate issues, and Armstrong addresses both of them. See Armstrong, 135 S. Ct. at
1382 (“Respondents . . . claim[] that Idaho violates § 30(A) by reimbursing [them] at
                                                                                (continued...)

                                             50
       At the second step, the Court decided that the providers were pleading two

supposed causes of action to vindicate those rights. Id. at 1383–85. Their first claim was

purportedly based on a right of action under the Supremacy Clause itself. Id. at 1383–84.

Their second claim was against the State “in equity.” Id. at 1385. They sought the same

prospective injunctive relief—higher rates of compensation—on both claims. Id. at 1382.

       At the third step, the Court determined whether each of those putative causes of

action stated a viable claim for the equitable relief requested—i.e., an injunction requiring

Idaho to compensate them with those federal funds at a higher rate. Id. at 1383–87.

       With respect to the providers’ first claim, the Court reiterated that “the Supremacy

Clause is not the ‘source of any federal rights,’” and held that the Clause “certainly does

not create a cause of action.”10 Id. at 1383 (quoting Golden State Transit Corp. v. City of

Los Angeles, 493 U.S. 103, 107 (1989)). The Clause “instructs courts what to do when

state and federal law clash, but is silent regarding who may enforce federal laws in court,

(...continued)
rates lower than § 30(A) permits.” (emphasis added)); id. at 1387 (“Their relief must be
sought initially through the” federal agency “rather than through the courts.” (emphasis
added)). The potential for relief presupposes the existence of a substantive right that has
been infringed upon. See, e.g., Franklin v. Gwinnett Cty. Pub. Sch., 503 U.S. 60, 65–66
(1992); Davis, 442 U.S. at 239–41. The disagreement between the majority and the
dissent in Armstrong was over whether the providers could obtain relief for the violation
of their claimed rights. See Armstrong, 135 S. Ct. at 1393 (Sotomayor, J., dissenting)
(urging relief “[i]f the State has violated § 30(A) by refusing to reimburse” the plaintiffs).
        A majority of the Justices in Armstrong at least assumed arguendo that the
providers had a right to be reimbursed, but denied equitable relief notwithstanding this.
Id. at 1387 (majority opinion). Here, however, the Reillys admit they have no such rights.
10
  We note the Court’s careful distinction between the “source of [a] federal right[]” and
the “creat[ion of] a cause of action.” Id. Again, these are separate issues. See, e.g.,
Franklin, 503 U.S. at 65–66; Davis, 442 U.S. at 239–41.

                                             51
and in what circumstances they may do so.” Id. The Supremacy Clause does not “give

affected parties a constitutional (and hence congressionally unalterable) right to enforce

federal law against the States.” Id. (emphasis added). Armstrong’s analysis of the

Supremacy Clause is particularly relevant here because the Court reiterated—in lockstep

with centuries of precedent—that the “Constitution gave Congress . . . broad discretion

with regard to the enactment of laws,” including “power over the manner of their

implementation,” such that Congress may “leave the enforcement of federal law to

federal actors.”11 Id. at 1383–84. We will discuss in detail how the Court’s precedents

instruct us to determine if Congress left enforcement of the CSA to federal actors in the

circumstances alleged here.

       In Armstrong, the Court last turned to the providers’ putative causes of action in

equity to vindicate their professed statutorily-created property rights. The Court began

this analysis by invoking two related bedrock principles that apply whenever an Article

III court sits in equity, as in law. “The power of federal courts of equity to enjoin

unlawful executive action is subject to express and implied statutory limitations.”12 Id.

11
  The Court’s remarks regarding the Supremacy Clause only serves to underscore how
odd it is that the Reillys and Safe Streets are suggesting that they have a lingering right in
equity to enforce every federal statute if they suffer any injury, and unless Congress
withdraws that so-called right. See id. In any event, the Reillys and Safe Streets have
abandoned any pretense that they raise causes of action under the Supremacy Clause.
12
  In Armstrong, these principles animated the Court’s discussion of whether,
notwithstanding the providers’ claims of a right to funds, Congress intended that “[t]heir
relief must be sought initially through” a federal agency “rather than through the courts.”
Id. at 1387. Here, the “statutory limitation[]” at issue, id. at 1385, is a threshold matter:
“where the text and structure of a statute provide no indication that Congress intends to
create new individual rights, there is no basis for a private suit” to enforce the statute.
                                                                                 (continued...)

                                              52
at 1385 (citing Seminole Tribe of Fla. v. Florida, 517 U.S. 44, 74 (1996)). Moreover,

“[c]ourts of equity can no more disregard statutory and constitutional requirements and

provisions than can courts of law.” Id. (quoting INS v. Pangilinan, 486 U.S. 875, 883

(1988)).

       Applying those principles, the Court adopted a two-pronged analytical framework

to decide if the providers’ claims for injunctive relief were viable. Id. at 1385–87.

Specifically, the Court concluded that “[t]wo aspects of § 30(A) establish Congress’s

‘intent to foreclose’ equitable relief” for the alleged violations of the providers’

substantive right to federal funds. Id. at 1385. “First,” the Court explained, “the sole

remedy Congress provided for a State’s failure to comply with Medicaid’s requirements

. . . is the withholding of Medicaid funds by the Secretary of Health and Human

Services.” Id. (citation omitted). Second, that narrow available remedy foreclosed

equitable relief “when combined with the judicially unadministrable nature of § 30(A)’s

text.” Id. The Court thus held that, despite the providers’ claim that their federal rights

were infringed, they could not recover. Id. at 1386–87.

       The Reillys and Safe Streets devote near-singular attention to that inquiry: whether

Congress foreclosed equitable relief for Colorado and Pueblo County’s purported

violations of the CSA, including § 903.13 Unlike the providers in Armstrong, however,

(...continued)
Gonzaga Univ. v. Doe, 536 U.S. 273, 286 (2002) (emphasis added).
13
  The Concurrence states that we “rel[y] largely on” Armstrong for our analysis of these
preemption claims. Concurrence at 1. In fact, we discuss Armstrong in detail because the
plaintiffs primarily rely on it to suggest that a multi-step inquiry is required to determine
                                                                                  (continued...)

                                              53
the Reillys and Safe Streets do not claim to have any substantive rights under § 903, or

any rights enumerated elsewhere in the CSA. But Armstrong itself relied on an initial

determination that the providers claimed to be vindicating their federal substantive rights

by enforcing the very federal statute that allegedly created those rights, § 30(A). Id.

at 1382. Moreover, Armstrong expressly stated the foundational principle that an Article

III court sitting in equity remains bound to a federal statute’s text. Id. at 1385.

       That is, of course, “[t]he elements of, and the defenses to, a federal cause of action

are defined by federal law.” Howlett v. Rose, 496 U.S. 356, 375 (1990). And

“substantive federal law itself . . . must be created by Congress.” Alexander v. Sandoval,

532 U.S. 275, 286 (2001) (citing Touche Ross & Co. v. Redington, 442 U.S. 560, 578

(1979)). The Reillys are undoubtedly correct that “[o]nce a right and a violation have

been shown, the scope of a [federal] court’s equitable powers to remedy . . . wrongs is

broad, for breadth and flexibility are inherent in equitable remedies.” Rizzo v. Goode,

423 U.S. 362, 376–77 (1976) (emphasis added). Moreover, “federal courts have

jurisdiction over suits to enjoin state officials from interfering with federal rights.” Shaw

v. Delta Air Lines, Inc., 463 U.S. 85, 96 n.14 (1983) (emphasis added) (citing Ex parte

(...continued)
whether Congress foreclosed private citizens from obtaining relief if a State violates the
CSA. As we explain in detail below, that inquiry is irrelevant here.
        As for the analysis of the actual issue before us, we rely largely on the Constitution
itself and over thirty Supreme Court cases (a sample), many of which Armstrong cites.
They explain, in short, that “where the text and structure of [the CSA] provide[s] no
indication that Congress intend[ed] to create new individual rights, there is no basis for a
private suit,” Gonzaga, 536 U.S. at 286, because Congress has not “mandat[ed] private
enforcement” of the CSA. Armstrong, 135 S. Ct. at 1384.

                                              54
Young, 209 U.S. 123, 160–62 (1908)). But, as in law, “in federal equity cases[,] ‘the

nature of the violation’” of a federal right “determines the scope of the remedy” available.

Rizzo, 423 U.S. at 378 (citation omitted).

       Critically, the Supreme Court has explained that “to invoke the” Article III courts’

equitable powers, a plaintiff asserting a cause of action to enforce a federal statute must

have “a federal right that [he or she] possesses against” the defendant. Va. Office for

Prot. & Advocacy v. Stewart, 563 U.S. 247, 260 (2011). “Such litigation cannot occur

unless the” plaintiff “has been given a federal right of” his or her “own to vindicate

. . . under the . . . statute at issue” in the case. Id. at 261 n.8 (emphasis added). Therefore,

unless a private plaintiff has been given a federal right of her or his own to vindicate in

the CSA, the plaintiff cannot maintain a cause of action—in law or in equity—against any

defendant for violating the CSA.14 Id.; see Lexmark, 134 S. Ct. at 1394 n.5.

       The Reillys suggest otherwise. But “[t]his principle has deep roots in our

jurisprudence.” Franklin v. Gwinnett Cty. Pub. Sch., 503 U.S. 60, 66 (1992). In

particular, “the question is which class of litigants may enforce in court legislatively

created rights or obligations. If a litigant is an appropriate party to invoke the power of

the courts, . . . he has a ‘cause of action’ under the statute,” which “is a necessary element

of his ‘claim.’” Davis, 442 U.S. at 239. And “the question of what remedies are

available under a statute that provides a private right of action is ‘analytically distinct’

14
  “[T]he question of who may enforce a statutory right is fundamentally different from
the question of who may enforce a right that is protected by the Constitution.” Davis, 442
U.S. at 241. That inquiry is not at issue in these appeals because none of the plaintiffs
claim to be vindicating any “right that is protected by the Constitution.” Id.

                                              55
from the issue of whether such a right exists in the first place.” Franklin, 503 U.S. at

65–66 (quoting Davis, 442 U.S. at 239).

       In turn, “private rights of action to enforce federal law must be created by

Congress.” Sandoval, 532 U.S. at 275 (citation omitted). We must “interpret the statute

Congress has passed to determine whether it displays an intent to create not just a private

right but also a private remedy.” Id. at 286 (citation omitted). The same threshold

inquiry applies when we ask “whether a statutory violation may be enforced through

§ 1983”—i.e., “we must first determine whether Congress intended to create a federal

right.” Gonzaga Univ. v. Doe, 536 U.S. 273, 283 (2002).

       Most importantly here, this threshold inquiry into whether the plaintiff has a

substantive right in the federal statute she or he seeks to enforce transcends the division

between law and equity. The Supreme Court has held that a “[c]ourt of equity cannot, by

avowing that there is a right but no remedy known to the law, create a remedy in violation

of law . . . .” Pangilinan, 486 U.S. at 883 (citations omitted), cited with approval in

Armstrong, 135 S. Ct. at 1385. We “will not engraft a remedy on a statute, no matter how

salutary, that Congress did not intend to provide.” Mass. Mut. Life Ins. Co. v. Russell,

473 U.S. 134, 145 (1985) (quoting California v. Sierra Club, 451 U.S. 287, 297 (1981)).

Rather, “Congress must have created a specific and uniquely federal right or remedy,

enforceable in a federal court of equity” for injunctive relief to issue. Mitchum v. Foster,

407 U.S. 225, 237 (1972).

       The Supreme Court succinctly summarized these well-established principles in

Stewart. Again, the Court stated that with respect to a plaintiff’s suit in equity to enforce

                                             56
a federal statute, “[s]uch litigation cannot occur unless the” plaintiff “has been given a

federal right of [their] own to vindicate . . . under the . . . statute at issue” in the case.

Stewart, 563 U.S. at 261 n.8 (emphasis added). Armstrong also invokes these precepts.

Specifically, the Court explained that the Supremacy Clause “is silent regarding who may

enforce federal laws in court, and in what circumstances they may do so.” Armstrong,

135 S. Ct. at 1383. The Court continued:

       If the Supremacy Clause includes a private right of action, then the
       Constitution requires Congress to permit the enforcement of its laws by
       private actors, significantly curtailing its ability to guide the implementation
       of federal law. It would be strange indeed to give a clause that makes
       federal law supreme a reading that limits Congress’s power to enforce that
       law, by imposing mandatory private enforcement . . . .

Id. at 1384.

       In sum, Congress, not the courts, creates federal statutory substantive rights, which

are prerequisites to private suits to enforce federal statutes. Therefore, as these cases all

explain, to determine whether a private plaintiff may enforce the CSA, we must first

determine whether that plaintiff has substantive rights in the CSA that he or she is seeking

to vindicate. See, e.g., Stewart, 563 U.S. at 261 n.8; Russell, 473 U.S. at 145; Mitchum,

407 U.S. at 237. Only if the CSA includes such rights will we have any call to determine

what causes of action are available to enforce those rights, and for what remedies.

       Consequently, to determine if the Reillys can enforce the CSA in equity, our

threshold inquiry is whether § 903 creates new federal substantive rights or incorporates

by reference a private citizen’s existing substantive rights, elevating them for federal

protection. Cf., e.g., 18 U.S.C. § 1964(c) (incorporating private common-law property

                                                57
rights into RICO). “For a statute to create such private rights, its text must be ‘phrased in

terms of the persons benefited.’” Gonzaga, 536 U.S. at 283 (quoting Cannon, 441 U.S. at

690 n.13). Contrariwise, “[s]tatutes that focus on the person regulated rather than the

individuals protected create ‘no implication of an intent to confer rights on a particular

class of persons.’” Sandoval, 532 U.S. at 289 (quoting Sierra Club, 451 U.S. at 294); see

also Armstrong, 135 S. Ct. at 1387 (plurality opinion of Scalia, J.) (“doubt[ing] . . . that

providers are intended beneficiaries . . . of the Medicaid agreement,” which also would

have foreclosed their claimed “private right of action under federal law”).

       Here, however, no discerning inquiry is necessary because the Reillys and Safe

Streets have never alleged that they have any substantive rights in § 903 or elsewhere in

the CSA by which they can enforce the CSA’s preemptive effects. Where a federal

statute “simply does not create substantive rights,” the Supreme Court has explained that

it is “unnecessary to address [any] remaining issues” about a private citizen’s ability to

enforce that statute or obtain relief. Pennhurst State Sch. & Hosp. v. Halderman, 451

U.S. 1, 11 (1981). The Reillys and Safe Streets were thus required to plausibly allege that

they are vindicating a federal substantive right to be able to maintain a cause of action in

equity of the type they assert here.15 But they failed to do so. This inexorably leads us to

conclude that the Reillys and Safe Streets have no viable causes of action against

15
  We will discuss in detail below the separate issue of preemption-based defenses to
criminal, civil, and regulatory enforcement actions. See infra note 19; see also
Armstrong, 135 S. Ct. at 1384 (noting these defenses, which were not implicated there,
either). It suffices to again remark that neither the Reillys nor Safe Streets have asserted
any such claim.

                                              58
Colorado or Pueblo County. See, e.g., Stewart, 563 U.S. at 260–61 & n.8.

       Finally, we note that Article III courts “will not . . . ‘entertain citizen suits to

vindicate the public’s nonconcrete interest in the proper administration of the laws.’”

Massachusetts v. EPA, 549 U.S. 497, 516–17 (2007) (citation omitted). That principle’s

force is even stronger when a private citizen attempts to vindicate a criminal statute. See,

e.g., Diamond v. Charles, 476 U.S. 54, 64 (1986) (holding a “private citizen lacks a

judicially cognizable interest in the prosecution or non[-]prosecution of another”). This

further buttresses our conclusion that the Reillys and Safe Streets cannot enforce the

CSA.

       D. The Reillys and Safe Streets’ calls to equity do not alter this conclusion

       The Reillys and Safe Streets attempt to avoid this result by drawing our attention

to numerous cases in which the Supreme Court has held that equitable relief is available.

But their fixation on federal equitable relief begs the question whether a private citizen

has a federal substantive right to begin with. Perhaps in antiquity a private citizen could

enter a judicial forum and demand equitable relief in the absence of any injury to a

protected substantive right. But such incantations almost certainly ceased to hold any

power in 1788. See U.S. Const. art. III, § 2.

       After all, for federal question jurisdiction to exist today, a “right or immunity

created by the Constitution or laws of the United States must be an element, and an

essential one, of the plaintiff’s cause of action.” Franchise Tax Bd., 463 U.S. at 10–11

(emphasis added) (quoting Gully v. First Nat’l Bank, 299 U.S. 109, 112 (1936)); see 28

U.S.C. § 1331. It therefore appears to be, at best, a highly dubious proposition that

                                               59
Article III courts have ever provided free-floating injunctive relief under federal statutes

for violations of individuals’ non-federal rights, whether sitting in law or in equity. Cf.

Gonzaga, 536 U.S. at 285 (noting that “one cannot go into court and claim a violation of

§ 1983—for § 1983 by itself does not protect anyone against anything”); see Douglas v.

Indep. Living Ctr. of S. Cal., Inc., 565 U.S. 606, 620 (2012) (Roberts, C.J., dissenting)

(“For a court to reach a contrary conclusion under its general equitable powers would

raise the most serious concerns regarding . . . the separation of powers . . . .”), cited with

approval in Armstrong, 135 S. Ct. at 1385 (delimiting courts’ equitable powers).

       In any event, we need not explore the ancient roots of equity to be certain of our

conclusion today. In Pennhurst State School & Hospital v. Halderman (Pennhurst II), 465

U.S. 89 (1984), the Supreme Court held that Article III courts sitting in equity are without

authority to remedy a State’s or its officers’ violations of State law; we may only grant

injunctive relief of this type to “vindicate federal rights . . . .” Id. at 105 (emphasis

added). The Reillys and Safe Streets have not cited any Supreme Court case16 postdating

Pennhurst II in which the Court countenanced injunctive relief of the type that they

request here for anything but an alleged violation of a private citizen’s federal substantive

rights recognized in the Constitution or bestowed by a federal statute.

16
  To the extent that the lower federal courts occasionally countenanced such putative
claims for injunctive relief in the guise of “right[s] of action under the Supremacy
Clause,” the Supreme Court explicitly rejected such theories when it held in Armstrong
that the Supremacy Clause “does not create a cause of action.” 135 S. Ct. at 1383
(quoting, and reversing, Exceptional Child Ctr., Inc. v. Armstrong, 567 F. App’x 496, 497
(9th Cir. 2014)), abrogating in part Planned Parenthood of Kan. & Mid-Mo. v. Moser,
747 F.3d 814, 817, 822–38 (10th Cir. 2014) (delineating a “Supremacy Clause claim”).

                                               60
       We have examined the cases they cited and numerous others both predating and

postdating Pennhurst II. Many of those precedents explicitly state that an Article III court

may vindicate federal rights in equity, with no mention of granting relief in their absence.

See id. at 105–06. And all of the other cases leave no doubt that the federal statutes (or

constitutional provisions) in question were the purported sources of the private plaintiffs’

substantive rights under consideration. See, e.g., Armstrong, 135 S. Ct. at 1382. No

modern authority supports the Reillys and Safe Streets’ hypothesis, which is the

foundation of their alleged causes of action in equity.17 Therefore, we conclude that the

Reillys and Safe Streets’ preemption claims fail as a matter of law.

                                        Conclusions

       In sum, we conclude that the Reillys and Safe Streets’ preemption claims against

Colorado and Pueblo County fail to state plausible claims upon which relief can be

granted. See Shields, 744 F.3d at 640. Accordingly, in No. 16-1048, we affirm the

district court’s order and its judgment in Safe Streets Alliance dismissing the Reillys and

Safe Streets’ preemption claims.

                                          III. Smith

       In Smith, a group of county attorneys and sheriffs from Colorado, Kansas, and

Nebraska brought a complaint against Colorado alleging distinct injuries but asserting

substantively identical theories why the CSA preempts Amendment 64.18 The district

court dismissed their claims. For the reasons just discussed, we likewise affirm.

                                       The allegations

       More specifically, the plaintiffs in Smith are Sheriffs Justin E. Smith, Chad Day,

Shayne Heap, Ronald B. Bruce, Casey Sheridan, and Frederick D. McKee of Colorado;

Sheriff Burton Pianalto of Kansas; Sheriffs Scott DeCoste, John D. Jenson, and Mark L.

Overman of Nebraska; County Attorney Charles F. Moser of Kansas; and County

Attorney Paul B. Schaub of Nebraska. The Colorado Sheriffs assert their claims only in

their individual capacities, whereas the other plaintiffs all sue in their individual

capacities and purportedly on behalf of their respective municipal offices. We refer to

them collectively as the “Law Enforcement Officers.”

18
  The Law Enforcement Officers also claim that Colorado’s actions violate several
international agreements, though again without purporting to have any substantive rights
under those accords. See Medellin v. Texas, 552 U.S. 491, 537 n.3 (2008). We need not
discuss those agreements further because the Law Enforcement Officers waived any such
claims by failing to brief them here. See Holmes, 762 F.3d at 1199.

                                              62
         The Colorado Sheriffs claim to have been harmed by the “enactment of

Amendment 64” because their “oath[s] of office to uphold the United States Constitution”

and the “Colorado Constitution” now “contradict each other.” No. 16-1095, Aplt. App.

at 45. Specifically, where they discover individuals in possession of marijuana—in

violation of the CSA but not in violation of Amendment 64—they allegedly must “choose

between violating” their oaths to one sovereign or the other. Id. at 46. They argue, for

example, that they “violate their oath[s] to uphold the” Constitution “when they fail to

take steps to enforce the CSA during” those “encounters and instead allow the illegal

marijuana to remain in the possession of the holder for use or further distribution.” Id.

at 47.

         However, they also concede that each of them “is aware that the CSA authorizes

him to seize . . . all marijuana he encounters during the course of performing his duties,

and to deliver such contraband” to the United States, “thereby both complying with and

enforcing the CSA.” Id. Yet the Colorado Sheriffs claim that if they were to seize that

marijuana, they would “be in violation of” their oaths “to uphold the Colorado

Constitution,” in some unspecified fashion. Id. They also allege that doing so would

create “legal exposure” for them and their respective counties. Id. at 48. Yet they do not

point to any feature of the CSA requiring them to seize marijuana they discover. Nor do

they claim that any provision of Amendment 64 requires them to refrain from seizing

marijuana, or that any order, policy, practice, or custom operates to similar effect. Like

all of the other Law Enforcement Officers, therefore, the Colorado Sheriffs do not

assert—and they certainly have never argued that they are asserting—federal defenses to

                                             63
enjoin Colorado from enforcing Amendment 64 against them.19

       The Kansas and Nebraska Sheriffs assert that when they discover motorists in

possession of marijuana, they “frequently learn” that those drivers “purchased the

marijuana in Colorado and were at the time of purchase in facial compliance with

Amendment 64.” Id. at 49. The Kansas and Nebraska Sheriffs complain of unspecified

19
  Of course, a “court may not convict a criminal defendant of violating a state law that
federal law prohibits. Similarly, a court may not hold a civil defendant liable under state
law for conduct federal law requires.” Armstrong, 135 S. Ct. at 1384 (citations omitted).
“[A]n actor seeking to satisfy both his federal- and state-law obligations is not required to
cease acting altogether in order to avoid liability.” Mut. Pharm. Co. v. Bartlett, __ U.S.
__, 133 S. Ct. 2466, 2477 (2013) (emphasis added). Moreover, “if an individual claims
federal law immunizes him from state regulation, the court may issue an injunction upon
finding the state regulatory actions preempted.” Armstrong, 135 S. Ct. at 1384 (citing Ex
parte Young, 209 U.S. at 155–56); see Fla. Lime & Avocado Growers, Inc. v. Paul, 373
U.S. 132, 157 (1963). In such circumstances, a court need only conduct a
“straightforward inquiry into whether [the] complaint alleges an ongoing violation of
federal law and seeks relief properly characterized as prospective.” Verizon, 535 U.S.
at 645–46 (citations omitted) (examining a request “that state officials be restrained from
enforcing an order” against the plaintiff that was allegedly “in contravention of
controlling federal law”).
       But a person’s constitutional defenses to extant or “threatened enforce[ment]”
actions, or to regulatory “expos[ure]” or “liability,” are all predicated on existing or
“threatened action by [the] government,” not by private actors. MedImmune, Inc. v.
Genentech, Inc., 549 U.S. 118, 128–29 (2007) (emphasis added). It is the official
“coercion” at issue (e.g., “putting the challenger to the choice between abandoning his
rights or risking prosecution”) that gives rise to such preemption-based defenses. Id.
at 129 (emphasis added).
       None of these doctrines even conceivably applies to the Colorado Sheriffs’ claims.
See Printz v. United States, 521 U.S. 898, 925–26 (1997) (explaining that the “Oath or
Affirmation[] to support this Constitution” required of “state officers,” id. at 924 (quoting
U.S. Const. art. VI, cl. 3), does not compel those officers to enforce federal statutes).
They do not suggest otherwise: they do not assert that they have a right to enforce the
CSA, that they are now required to violate the CSA, or that Colorado is threatening to
punish them if they choose to uphold what they perceive to be their oaths to enforce that
federal statute. Like all of the other Law Enforcement Officers, therefore, the Colorado
Sheriffs are not attempting to raise preemption-based defenses.

                                             64
injuries to their individual “professional goals” caused by this alleged influx of

“Colorado-sourced marijuana” into their respective counties. Id. at 51. They also claim

that their respective offices have experienced “a marked increase in the costs” of

incarcerating “suspected and convicted felons” following “arrests” involving “Colorado-

sourced marijuana,” and that they now spend much more time on these particular law

enforcement activities. Id. at 49–50. The Kansas and Nebraska County Attorneys

likewise claim that they have been forced to alter their individual professional aspirations

and their offices’ prosecutorial priorities in light of the increased influx of “Colorado-

sourced marijuana” into their respective counties. Id. at 52.

       Finally, although the Attorney General has authority “to deputize state and local

law enforcement officers to” enforce the CSA, id. at 24 (citing 21 U.S.C. § 878), none of

the Law Enforcement Officers allege that they have been deputized by the Attorney

General to enforce § 903 against Colorado, or to enforce the CSA in any other respect.

Therefore, designated authority to enforce the CSA does not bear on these claims.

       To remedy their specific putative injuries, the Law Enforcement Officers instead

claim to invoke the federal courts’ equitable power to enjoin Governor Hickenlooper, in

his official capacity, from enforcing Amendment 64. To that end, they allege two “causes

of action” against Colorado. Id. at 54 (emphasis and capitalization omitted). First, they

assert that “Sections 16(3)[–](5) of Amendment 64, taken in whole and in part,” are

“drug-legalization and drug-regulation policies” that “legalize and commercialize”

recreational marijuana. Id. at 54–55. Because those provisions of Amendment 64

allegedly “conflict with” the CSA, the Law Enforcement Officers claim that they “violate

                                              65
the Supremacy Clause, and are invalid.” Id. at 55. Second, the Law Enforcement

Officers claim “preemption under federal law,” and assert that “Sections 16(3)[–](5) of

Amendment 64 are preempted by federal law, including” the CSA. Id. (emphasis and

capitalization omitted). They request a “declaratory judgment stating that Sections 16(3),

(4), and (5) of Article XVIII of the Colorado Constitution are invalid, null, and void,” and

a “permanent injunction” barring enforcement of these provisions. Id.

       The district court dismissed those claims for substantively the same reasons as it

did the Reillys and Safe Streets’ preemption claims. The Law Enforcement Officers

timely appealed, which is before us as No. 16-1095. At the parties’ request, we

consolidated that appeal with the Reillys and Safe Streets’ appeal in No. 16-1048.

                                          Analysis

       The Law Enforcement Officers do not allege any specific substantive rights

bestowed on them by the Supremacy Clause or the CSA that they seek to vindicate. More

specifically, they concede that the Supremacy Clause creates no substantive rights and

“does not give rise to a private right of action,” mooting their first purported claim for

relief. Id. at 95. And they do not invoke any substantive right found in the CSA, or

elsewhere, that animates their second alleged cause of action. For example, the allegedly

beleaguered Kansas and Nebraska Sheriffs do not contend that any provision of the CSA

creates or even references a private citizen’s labor rights, professional development

“rights,” or financial interests, or those of their respective law enforcement offices.

       Instead, like the Reillys and Safe Streets, the Law Enforcement Officers seek to

proceed on their claims merely by emphasizing that “an action may proceed in equity

                                              66
unless Congress implicitly or expressly excludes such an action.” Id. at 96 (citation

omitted). They have maintained that theme here, asserting that “a party may seek

injunctive relief against a state for its failure to abide by federal law unless Congress

implicitly or expressly excludes such an action.” No. 16-1095, Aplt. Br. at 25. Thus,

they claim that “the enforcement of the CSA is not confined to a governing federal

agency,” even in the absence of delegated authority to enforce that statute. Id. at 33.

                                 Subject matter jurisdiction

       We again face a threshold question of subject matter jurisdiction. See Ruiz, 536

U.S. at 628; Shepherd, 678 F.3d at 1180. Like the Reillys and Safe Streets, the Law

Enforcement Officers pled that they have federal causes of action in equity to enforce the

CSA, though they also do not claim to be vindicating any substantive rights enumerated

in that federal statute. As discussed above, the viability of these claims turns, in part, on a

determination of the scope of the Article III courts’ equitable power to grant injunctive

relief, a question the district court had jurisdiction to answer under § 1331. See Nat’l

Farmers Union, 471 U.S. at 850. Relatedly, moreover, the Law Enforcement Officers’

“right to relief necessarily depends on resolution of a substantial question of federal law,”

a question properly addressed by the district court in Smith as within its subject matter

jurisdiction under § 1331. Franchise Tax Bd., 463 U.S. at 13; see Bolivarian Rep. of

Venez., 137 S. Ct. at 1322; Gunn, 133 S. Ct. at 1065; Empire Healthchoice, 547 U.S.

at 697; Grable, 545 U.S. at 314; see also Steel Co., 523 U.S. at 89. In No. 16-1095,

therefore, we also have jurisdiction of the Smith appeal. 28 U.S.C. § 1291.

                                              67
               The Law Enforcement Officers’ claims fail as a matter of law

       Like the Reillys and Safe Streets, the Law Enforcement Officers advance

purported causes of action in equity to enforce the CSA’s preemptive effects, but in the

absence of any claimed injury to their federal substantive rights. “On the merits,” the

Law Enforcement Officers’ “case raises the same question” that we have already

answered in the negative in Safe Streets Alliance: A private plaintiff has no substantive

rights under, and cannot enforce, § 903. Norton v. Mathews, 427 U.S. 524, 525 (1976).

The “outcome of” the Law Enforcement Officers’ case is thus “foreordained by” our

dismissal of the Reillys’ claims in this consolidated appeal. Steel Co., 523 U.S. at 98

(explaining that Norton “involv[ed] a merits issue dispositively resolved in a companion

case”); see Horne v. Flores, 557 U.S. 433, 438, 445 (2009) (similarly resolving

“consolidated cases,” id. at 438, where “at least one” plaintiff in one of the appeals raising

the same question “ha[d] ‘alleged such a personal stake in the outcome of the controversy

as to warrant his invocation of federal-court jurisdiction,’” id. at 445 (citation omitted));

Bowsher v. Synar, 478 U.S. 714, 717–21 (1986) (same).

       Accordingly, in No. 16-1095, we affirm the district court’s order and its judgment

dismissing the Smith case on the merits and with prejudice. See Mont.-D. Utils. Co. v.

Nw. Pub. Serv. Co., 341 U.S. 246, 249 (1951) (“Even a patently frivolous complaint

might be sufficient to confer power to make a final decision that it is of that nature,

binding as res judicata on the parties.”).

                                              68
                              IV. Nebraska and Oklahoma

       One final wrinkle developed after these cases came before us. At the same time

that the underlying actions were proceeding in the district court, Nebraska and Oklahoma

filed an original complaint against Colorado in the Supreme Court of the United States,

pursuant to the Court’s “original and exclusive jurisdiction of all controversies between

two or more States.” 28 U.S.C. § 1251(a). There, Nebraska and Oklahoma conceded that

“[t]he Court’s jurisdiction” over their “case is exclusive,” and the Supreme Court “is the

sole forum in which Nebraska and Oklahoma may enforce their rights” against Colorado

“under the Supremacy Clause . . . .” Complaint at 1, Nebraska v. Colorado, __ U.S. __,

136 S. Ct. 1034 (2016) (No. 144, Original), 2014 WL 7474136, at *1.

       Like the private plaintiffs here, Nebraska and Oklahoma attempted to enjoin

enforcement of Subsections 4 and 5 of Amendment 64. The States claimed those

enactments conflict with the CSA and are therefore preempted by operation of the

Supremacy Clause and § 903. The scope of relief they requested was thus narrower but

overlapping with that demanded in the instant cases. Yet the theories by which the States

sought to force Colorado to comply with the CSA were of a distinct order, premised on

their alleged rights as separate sovereigns in our federal system. They claimed to be

empowered to enforce federal law both for their own benefit, as sovereigns, and for the

good of their citizens, in the States’ quasi-sovereign capacities as parens patriae.

       The Supreme Court exercised its discretion to decline to hear such inter-state

actions and consequently denied Nebraska and Oklahoma’s motion for leave to file their

complaint. Nebraska, 136 S. Ct. at 1034. Justice Thomas dissented, urging the Court to

                                             69
revisit its precedent holding that it has discretion to decline to hear cases and

controversies over which Article III and § 1251(a) vest it with original and exclusive

jurisdiction. Id. at 1034–36 (Thomas, J., dissenting). In doing so, Justice Thomas also

remarked (presciently, as it turns out) that “Federal law is unambiguous: If there is a

controversy between two States, this Court—and only this Court—has jurisdiction over

it.” Id. at 1034. “If this Court does not exercise jurisdiction over a controversy between

two States,” Justice Thomas cautioned, “then the complaining State has no judicial forum

in which to seek relief.” Id. at 1035 (emphasis added) (citation omitted).

                                       The allegations

       Justice Thomas’ warning and Nebraska and Oklahoma’s own prior concessions

apparently were soon forgotten. The States next moved to intervene on appeal in Safe

Streets Alliance and Smith, urging us to exercise jurisdiction over their controversy with

Colorado stemming from its implementation of Amendment 64. More specifically, they

sought to intervene as of right under Federal Rule of Civil Procedure 24(a), and claimed

to meet the additional burdens we have said a party must shoulder to intervene on appeal.

       Nebraska and Oklahoma then recapitulated their previous concession that “[t]he

Supreme Court is the only court with jurisdiction to hear suits of the sort brought by”

them. Mot. to Intervene by States of Neb. & Okla. at 3. The “result,” they claimed, is

“that there is no court with jurisdiction to hear Nebraska and Oklahoma’s suit directly

against the State of Colorado.” Id. Yet the States pointed to no statute, rule, or precedent

preventing them from refiling their original complaint in the Supreme Court, pursuant to

§ 1251(a). We also have found none.

                                              70
       As to the controversy now before us, Nebraska and Oklahoma framed their

interests as protective of their rights to “[a]n action” or “suit for declaratory and

injunctive relief against the Colorado officials responsible for executing the challenged

Colorado laws”—i.e., Amendment 64. Id. They suggested that they should be permitted

to intervene in the appeals because if they were “to initiate such a suit in district court” on

their own, we might “have in the interim decided the critical issue of whether there is a

cause of action to challenge Colorado’s marijuana laws as preempted by the CSA,” and in

their absence. Id. In doing so, however, Nebraska and Oklahoma ignored glaring

distinctions between their putative causes of action—which are premised on their status

as sovereigns—and the private citizens’ claims in Safe Streets Alliance and Smith.

       Nebraska and Oklahoma next purported to circumvent § 1251(a)’s unambiguous

command that this court is forbidden from exercising jurisdiction over their claims by

framing their challenge to Amendment 64 as a controversy over Governor Hickenlooper’s

enforcement of it. Yet Nebraska and Oklahoma repeatedly stated that the grievances they

brought before us and claims they plan to file are exactly the same as those they asserted

directly against Colorado in the Supreme Court. That concession is integral, for example,

to their argument that their intervention on appeal is timely. What they are seeking to

challenge is also undisputed: Colorado’s authority to enforce its Constitution, laws, and

regulations. Moreover, even as Nebraska and Oklahoma obliquely avoided stating that

their claims are against their sister sovereign, nowhere in their motions did they purport to

deny that their controversy is with Colorado, and thus barred here by § 1251(a).

       To assure ourselves that we lack jurisdiction to hear Nebraska and Oklahoma’s

                                              71
dispute, we allowed the States to fully ventilate their novel jurisdictional theory in

briefing. The States additionally requested to participate in oral argument. To

accommodate the States’ request despite their then neither being appellants, appellees,

nor amici curiae, we granted the motion to intervene in No. 16-1048, which permitted

them to participate in oral argument. See Fed. R. App. P. 27(e), 29(a)(8), 34; 10th Cir. R.

34.1(F).

       Nebraska and Oklahoma have now said all that they wish to say on the subject of

our jurisdiction over their grievances with Amendment 64. We now must decide whether

§ 1251(a) bars us from hearing their controversy. If so, that determination necessarily

forbids their continued intervention. They cannot shoulder their burden under Rule 24(a)

if we are barred from determining that they have any viable interests adverse to Colorado,

nor can they meet the requirements to intervene on appeal. Moreover, the distinct nature

of Nebraska and Oklahoma’s putative sovereign causes of action means that we must

address these issues separately from our disposition of the private plaintiffs’ claims.

                                          Analysis

       Nebraska and Oklahoma seek to intervene to protect their avowed interests in

enjoining the enforcement of Amendment 64 as allegedly preempted by the CSA. The

States thus come before us positioned analogously to intervening defendants in a

declaratory judgment action—requesting to enter the Article III courts for the purposes of

defending an interest in an underlying controversy in which they are the plaintiffs. In

turn, the underlying declaratory and injunctive relief the States seek to obtain largely

mirrors—though is not as extensive as—the relief that the private plaintiffs demanded.

                                             72
       Yet “States are not normal litigants for the purposes of invoking federal

jurisdiction.” Massachusetts, 549 U.S. at 518. Here, for example, the theories on which

Nebraska and Oklahoma purport to have causes of action arise from their unique powers

as sovereigns. See, e.g., Michigan v. Bay Mills Indian Cmty., __ U.S. __, 134 S. Ct.

2024, 2031 (2014) (explaining that “each State at the Constitutional Convention

surrendered its immunity from suit by sister States”). The States’ alleged injuries also

derive from their professed commitments to their citizens as parens patriae, as well as

various rights they claim to have as sovereigns, including, they aver, to force Colorado to

comply with the CSA. See Alfred L. Snapp & Son, Inc. v. Puerto Rico ex rel. Barez, 458

U.S. 592, 601–02 (1982) (discussing the States’ sovereign, proprietary, and private

interests, and their interests as parens patriae).

       Our disposition of the private citizens’ preemption claims therefore does

not—indeed, could not—affect Nebraska or Oklahoma’s putative sovereign claims, their

sole stated interests supporting intervention on appeal here. See Mississippi v. Louisiana,

506 U.S. 73, 78 (1992) (explaining that “[t]he States, of course, are not bound by any

decision as to the boundary between them which was rendered in a lawsuit between

private litigants” (citing Durfee v. Duke, 375 U.S. 106, 115 (1963)). But that also means

our conclusion here that the private citizens’ preemption claims fail neither resolves nor

moots whether Nebraska and Oklahoma actually have such interests.20

20
  The Concurrence states that it “need not address the jurisdictional issue” because, in its
view, Nebraska and Oklahoma’s “claims fall with those of the” private plaintiffs.
Concurrence at 11. To the contrary, however, these unique claims premised on alleged
                                                                                (continued...)

                                              73
       All of the officers’ conduct with which Nebraska and Oklahoma take issue is

allegedly in compliance with and in furtherance of Colorado law. See Pennhurst II, 465

U.S. at 101 n.11 (holding that “a state officer may be said to act ultra vires only when he

acts ‘without any authority whatever’” (citations omitted)). This confirms both that the

States’ putative claims are against Colorado and that their alleged interests here are in

supposed vindication of those claims. That conclusion is buttressed by Nebraska and

Oklahoma’s grievances aimed at Governor Hickenlooper’s enforcement of

Amendment 64. “[W]here the chief magistrate of a state is sued, not by his name, but by

his style of office, and the claim made upon him is entirely in his official character,” the

Supreme Court has long held that “the state itself may be considered as a party on the

record.” Governor of Ga. v. Madrazo, 26 U.S. 110, 123–24 (1828).

       Further, Nebraska and Oklahoma are mistaken that limiting their putative

sovereign claims to demands for prospective injunctive relief obtains a different result.

“[A] suit against a state official in his or her official capacity is not a suit against the

official but rather is a suit against the official’s office,” which “is no different from a suit

against the State itself.” Will v. Mich. Dep’t of State Police, 491 U.S. 58, 71 (1989)

(citations omitted). “And the same must be said of a directive to an official in his or her

official capacity.” Printz v. United States, 521 U.S. 898, 931 (1997).

(...continued)
sovereign rights are not addressed in our discussion of the private citizens’ claims and
must therefore be addressed separately.

                                               74
       The States invoke the caveat that “official-capacity actions for prospective relief

are not treated as actions against the State” for the purposes of sovereign immunity.

Kentucky v. Graham, 473 U.S. 159, 170 n.14 (1985) (emphasis added) (citing Ex parte

Young, 209 U.S. 123). But that “fiction” is inapplicable to the States’ charges. Idaho v.

Coeur d’Alene Tribe of Idaho, 521 U.S. 261, 270 (1997). For in no event could their

allegations implicate sovereign immunity, because “the Constitution did not reflect an

agreement between the States to respect the sovereign immunity of one another,” which is

typified here by the States’ proceedings directly against Colorado on these same claims in

the Supreme Court. Alden v. Maine, 527 U.S. 706, 738 (1999). Thus, our order granting

Nebraska and Oklahoma’s motion to intervene in No. 16-1048 held that the States were

protecting an interest adverse to Colorado.

       We also note that Rule 24(a)’s provisions cannot remove the Article III hurdle that

anyone faces when voluntarily seeking to enter a federal court, see Wittman v.

Personhuballah, __ U.S. __, 136 S. Ct. 1732, 1735–37 (2016), a proposition confirmed by

the title of the Rule itself: “Intervention of Right.” Fed. R. Civ. P. 24(a). The Supreme

Court has held, moreover, that Article III’s requirements apply to all intervenors, whether

they intervene to assert a claim or defend an interest. See Wittman, 136 S. Ct. at

1735–37; Hollingsworth v. Perry, __ U.S. __, 133 S. Ct. 2652, 2659–65 (2013) (holding

that “any person invoking the power of a federal court must demonstrate standing to do

so,” id. at 2661, and that a prerequisite to “intervene[] to defend” one’s interest is, inter

alia, “assert[ing] an injury in fact of [one’s] own,” id. at 2664), abrogating in part San

Juan Cty. v. United States, 503 F.3d 1163, 1172 (10th Cir. 2007) (en banc) (which had

                                              75
stated “that parties seeking to intervene under Rule 24(a) or (b) need not establish Article

III standing so long as another party with constitutional standing on the same side as the

intervenor remains in the case,” but tacitly acknowledged the intervenors had standing).

       Consequently, even though the private litigants’ preemption claims fail, our still-

extant order granting Nebraska and Oklahoma’s motion to intervene in Safe Streets

Alliance necessarily implies that, at minimum, the States have some concrete,

particularized, and redressable claim against Colorado, in turn permitting their

intervention in this court to defend that interest. We have given the States exceptional

leeway to advance counterarguments to this unavoidable conclusion. But the only

authority the States point to is wholly unavailing. For the reasons stated in then-Judge

Sotomayor’s dissent, we reject Connecticut v. Cahill’s unsupported declaration that the

lower federal courts are vested with jurisdiction over inter-state disputes naming State

officers as defendants. 217 F.3d 93, 105–12 (2d Cir. 2000) (Sotomayor, J., dissenting).

We therefore conclude that Nebraska and Oklahoma’s controversy is against Colorado.

       However, Section 1251(a) of Title 28 of the United States Code states: “The

Supreme Court shall have original and exclusive jurisdiction of all controversies between

two or more States.” The Court has held that the “plain meaning” of that

“uncompromising language . . . necessarily denies jurisdiction of such cases to any other

federal court,” regardless of the consequences to a State’s claims. Mississippi, 506 U.S.

at 77–78. Section 1251(a) forbids us from deciding whether Nebraska or Oklahoma have

any injuries from, claims against, or controversies with Colorado, which is what our

extant order necessarily does. Therefore, in No. 16-1048, we vacate the order granting

                                             76
Nebraska and Oklahoma’s motion to intervene in Safe Streets Alliance. Further, and for

the same reason, we deny the States’ motions to intervene in Nos. 16-1048 and 16-1095.

                                    V. Conclusions

      The parties dispute whether Amendment 64 is preempted by the CSA. Our

conclusions regarding the preemption claims do not require us to reach that question. We

therefore do not decide whether the CSA preempts any aspect of Amendment 64, or

Colorado and Pueblo County’s laws or regulations.

      Rather, in No. 16-1266, the district court’s order and its judgment dismissing

Counts I through VI of the Second Amended Complaint in Safe Streets Alliance are

AFFIRMED in part and REVERSED in part as follows:

      •      The dismissal of the Reillys’ RICO claims against the Marijuana
             Growers premised on one (or more) of the three types of injuries to
             the Reillys’ property that were plausibly pled is REVERSED, and
             those claims are reinstated.

      •      The dismissal of the Reillys’ RICO claims against the Marijuana
             Growers premised on any other injury is AFFIRMED.

      •      The dismissal of Safe Streets’ RICO claims and of the Reillys’
             RICO claims against every other defendant is AFFIRMED.

      In No. 16-1048, the district court’s order and its judgment dismissing with

prejudice the Reillys and Safe Streets’ preemption claims, Counts VII and VIII of the

First Amended Complaint in Safe Streets Alliance, are AFFIRMED.

      In No. 16-1095, the district court’s order dismissing with prejudice the Law

Enforcement Officers’ claims and its judgment in Smith are AFFIRMED.

      Our order granting Nebraska and Oklahoma’s motion in No. 16-1048 to intervene

                                           77
in Safe Streets Alliance is VACATED. Nebraska and Oklahoma’s motions to intervene

in Nos. 16-1048 and 16-1095 are DENIED.

      Finally, therefore, Counts I through VI of the Second Amended Complaint in Safe

Streets Alliance are REMANDED for further proceedings consistent with this opinion.

16-1048, Safe Streets, et al. v. Alternative Holistic

HARTZ, Circuit Judge, concurring:

       I join the disposition and discussion of the RICO claims on pages 10–35 of the

panel opinion. It is my hope, however, that the Supreme Court will one day cast aside the

confusing and discredited notion of proximate cause. A much sounder approach to

addressing the same issues can be found in the discussions of factual cause and scope of

liability in Chapters 5 and 6 of Restatement (Third) of Torts: Liability for Physical and

Emotional Harm (2010).

       Although I also agree with the panel majority to affirm the denial of injunctive

relief, my reasoning is different.

       First, I explain why I cannot join the majority’s approach. The majority declares

that even if state and local law is preempted by the Controlled Substances Act (CSA), the

plaintiffs cannot seek injunctive relief against those laws under the federal courts’ equity

powers because neither the CSA nor any other federal law bestows on them a substantive

private right. See Maj. Op. at 49–61. To determine whether a statute creates a private

right, the majority adopts the same test used by the Supreme Court in determining

whether to recognize an implied cause of action under the statute and whether the statute

creates a private right necessary for a cause of action under 42 U.S.C. § 1983. See id.

at 56 (quoting Alexander v. Sandoval, 532 U.S. 275, 289 (2001) (federally created right

necessary for implied private right of action) and Gonzaga University v. Doe, 536 U.S.

273, 283 (2002) (federally created right necessary for claim under § 1983)). For this

proposition the majority relies largely on the Supreme Court’s recent decision in
Armstrong v. Exceptional Child Center, Inc., 135 S.Ct. 1378 (2015). See Maj. Op. at 49–

58.

       In my view, however, Armstrong provides no support for the majority’s

requirement of a private right created by federal law. The Court’s opinion never states

that there is such a requirement. And if Armstrong itself or any earlier Supreme Court

precedent had imposed that requirement, both the Court’s opinion in Armstrong and

Justice Sotomayor’s dissent would have been written very differently. The following

discussion of Armstrong is lengthy, but I think it shows that the opinions in that case,

rather than adopting a substantive-right requirement, demonstrate its absence.

       In Armstrong the Supreme Court considered the mandate in § 30(A) of the

Medicaid Act that each State’s Medicaid plan “provide such methods and procedures

relating to . . . the payment for . . . care and services . . . as may be necessary . . . to assure

that payments . . . are sufficient to enlist enough providers so that care and services are

available under the plan at least to the extent that such care and services are available to

the general population in the geographic area . . . .” 42 U.S.C. § 1396a(a)(30)(A).

Health-care providers in Idaho contended that the State’s plan violated § 30(A) by setting

inadequate reimbursement rates. To put the issue in Armstrong in context, it is helpful to

review the possible forms of relief that the providers could have tried to pursue.

       The only remedy explicitly set forth in the Medicaid statute permits the Secretary

of Health and Human Services to withhold Medicaid funds from the State. See 42 U.S.C.

§ 1396c. Providers seeking more generous payments could try to persuade the Secretary

to exercise that authority, but the Secretary’s decision not to take such a step could be

                                             2
successfully challenged in court under the Administrative Procedure Act (APA) “only

when the denial of enforcement [was] ‘arbitrary, capricious, an abuse of discretion, or

otherwise not in accordance with law.’ 5 U.S.C. § 706(2)(A).” Pharm. Research &

Mfrs. of Am., v. Walsh, 538 U.S. 644, 675 (Scalia, J., concurring).

        Another possible remedy would be to bring a civil-rights claim against state

officials. Under the federal civil-rights statute, state officials could be liable to the

providers if they deprived the providers “of any rights, privileges, or immunities secured

by the [federal] Constitution and laws.” 42 U.S.C. § 1983. Relief could be obtained

through “an action at law, suit in equity, or other proper proceeding for redress.” Id.

Actions at law under § 1983 typically provide an injured party with damages, so the

providers could sue for payments that should have been made if federal law had been

followed. But relief under § 1983 is available only if the injured party was deprived of

some personal “right,” not just a benefit, conferred by federal law. See Gonzaga, 536

U.S. at 283. Only “an unambiguously conferred right [can] support a cause of action

brought under § 1983.” Id. “For a statute to create such private rights, its text must be

phrased in terms of the persons benefited.” Id. at 284.

       A similar remedy would be a suit under a private right of action implied from a

particular statute. Damages would also be a potential remedy under such a cause of

action. But this cause of action, like one under § 1983, is available only if “Congress

intended to create a federal right.” Id. at 283.

       None of these three potential remedies (a suit under the APA against the Secretary,

a suit under § 1983, or a private right of action implied under the Medicaid Act) was at

                                            3
issue in Armstrong. Rather, the Idaho providers sought only to enjoin state officials to

increase those rates prospectively. See 135 S.Ct. at 1382. Of course, the providers might

have obtained much greater relief (damages for payments that should have been made in

the past had reimbursement rates been set in compliance with § 30(A)) if they had

proceeded under § 1983 or an implied statutory cause of action. But they had no choice,

because (as will be further discussed below) the Medicaid Act does not contain the

necessary rights-creating language and hence had not conferred on them an individual

right. All that remained was a possible equitable preemption action, which would not

require rights-creating statutory language. As explained in Justice Sotomayor’s dissent:

       [E]quitable preemption actions differ from suits brought by plaintiffs
       invoking 42 U.S.C. § 1983 or an implied right of action to enforce a federal
       statute. Suits for redress designed to halt or prevent the constitutional
       violation rather than the award of money damages seek traditional forms of
       relief. By contrast, a plaintiff invoking § 1983 or an implied statutory
       cause of action may seek a variety of remedies—including damages—from
       a potentially broad range of parties. Rather than simply pointing to
       background equitable principles authorizing the action that Congress
       presumably has not overridden, such a plaintiff must demonstrate specific
       congressional intent to create a statutory right to these remedies. For these
       reasons, the principles that we have developed to determine whether a
       statute creates an implied right of action, or is enforceable through § 1983,
       are not transferable to [this] context.

Armstrong, 135 S.Ct. at 1392 (Sotomayor, J., dissenting) (citations and internal quotation

marks omitted) (emphasis added).

       Although the Supreme Court majority denied the providers’ claim, it did not

quarrel with this summary by Justice Sotomayor. Much of the Supreme Court’s opinion

was devoted to rejecting the argument that the Constitution’s Supremacy Clause gave the

providers a cause of action to enjoin the imposition of state law on the ground that it was

                                          4
contrary to federal law. See id. at 1383–84; see also Planned Parenthood v. Moser, 747

F.3d 814, 822–38 (10th Cir. 2014) (rejecting the same argument). The Court then turned

to the providers’ “contention that, quite apart from any cause of action conferred by the

Supremacy Clause, [their] suit can proceed against Idaho in equity.” 135 S.Ct. at 1385.

Noting that “[t]he power of federal courts of equity to enjoin unlawful executive action is

subject to express and implied statutory limitations,” the Court proceeded to conclude

that “[t]wo aspects of § 30(A) establish Congress’s intent to foreclose equitable relief.”

Id. (internal quotation marks omitted). First, it said that the statutory provision of a

different remedy for a State’s failure to comply with Medicaid requirements (the

Secretary can withhold Medicaid funds from the State) suggested that Congress intended

to preclude other remedies. See id. Second, it thought that the text of § 30(A) provided a

“judicially unadministrable” standard. Id. at 1394. “Explicitly conferring enforcement of

this judgment-laden standard upon the Secretary alone,” said the Court, “establishes, we

think, that Congress wanted to make the agency remedy that it provided exclusive.” Id.

at 1385 (internal quotation marks omitted). The Court concluded, “The sheer complexity

associated with enforcing § 30(A), coupled with the express provision of an

administrative remedy, . . . shows that the Medicaid Act precludes private enforcement of

§ 30(A) in the courts.” Id.

       The panel opinion describes Armstrong somewhat differently. It states that the

Supreme Court first “discerned what alleged substantive rights the plaintiffs were seeking

to vindicate,” and observed that the health-care providers were seeking “to vindicate their

averred federal property rights to . . . funds [reimbursing them for habilitation services],

                                           5
rights allegedly bestowed on them by § 30(A).” Maj. Op. at 50. But I can find no

language in Armstrong stating that the Court should “first” (or ever, when examining the

federal courts’ equity power) concern itself with whether the party seeking injunctive

relief alleged any federal substantive right. Nor did the opinion ever say that the

providers possessed or even asserted such a right. According to the panel opinion, the

Supreme Court was engaged in this “first step” in its analysis when it noted that the

plaintiffs were health-care providers “who ‘claim[ed] that Idaho violates § 30(A)’ of

Medicaid ‘by reimbursing [them] at rates lower than § 30(A) permits.’” Id. (quoting

Armstrong, 135 S.Ct. at 1382) (brackets in the panel opinion). But the language quoted

from Armstrong was in the fourth paragraph of that opinion, merely setting forth the

factual background before beginning any analysis. And nothing suggests that the Court

thought that the health-care providers were making the frivolous argument that § 30(A),

which provided the prospect of greater benefits for the providers, conferred any rights on

them.

        Indeed, Justice Scalia, whose opinion was the opinion for the majority of the Court

on the issues I have already discussed, said just the opposite in a portion of his opinion

joined by three other Justices (Justice Breyer, who otherwise joined Justice Scalia’s

opinion, did not join this portion of the opinion). He pointed out that the health-care

providers did not—and could not—claim that they had a statutorily created right:

        The last possible source of a cause of action for [the providers, once the
        Supremacy Clause and equity had been rejected as possible sources,] is the
        Medicaid Act itself. They do not claim that, and rightly so. Section 30(A)
        lacks the sort of rights-creating language needed to imply a private right of
        action. Sandoval, [532 U.S.] at 286–287. It is phrased as a directive to the

                                           6
       federal agency charged with approving state Medicaid plans, not as a
       conferral of the right to sue upon the beneficiaries of the State’s decision to
       participate in Medicaid. The Act says that the “Secretary shall approve any
       plan which fulfills the conditions specified in subsection (a),” the
       subsection that includes § 30(A). 42 U.S.C. § 1396a(b). We have held that
       such language “reveals no congressional intent to create a private right of
       action.” Sandoval, supra at 289.

135 S.Ct. at 1387 (plurality opinion of J. Scalia) (emphasis added). The same point is

conveyed, albeit a bit obscurely, in the portion of Justice Scalia’s opinion that received

support from the majority of the Court:

       [The providers] do not claim that Wilder [v. Virginia Hospital Assn., 496
       U.S. 498 (1990)] establishes precedent for a private cause of action in this
       case. They do not assert a § 1983 action, since our later opinions plainly
       repudiate the ready implication of a § 1983 action that Wilder exemplified.
       See Gonzaga Univ. v. Doe, 536 U.S. 273, 283 (2002) (expressly “rejecting
       the notion,” implicit in Wilder, “that our cases permit anything short of an
       unambiguously conferred right to support a cause of action brought under
       § 1983”).

135 S.Ct. at 1386 n.*(brackets omitted). I read this footnote as stating that the providers

did not claim a cause of action under § 1983 because they recognized (as they had to) that

such a claim must be based on a federally conferred right.

       No Justice expressed any doubt about these statements in Justice Scalia’s opinion.

In particular, as previously noted, Justice Sotomayor’s dissent on behalf of four Justices

(who would have granted injunctive relief) did not dispute that the providers lacked a

statutorily created private right. Rather, assuming that this was common ground with the

majority, it explicitly distinguished “equitable preemption actions from suits brought by

plaintiffs invoking 42 U.S.C. § 1983 or an implied right of action to enforce a federal

                                           7
statute,” on the ground that relief under “background equitable principles” is proper even

when Congress did not create a statutory right. Id. at 1392 (Sotomayor, J., dissenting).

       Moreover, if, as the panel opinion asserts, Armstrong was following long-standing

Supreme Court precedent requiring a statutorily created right, I cannot imagine why the

Justices wrote their opinions as they did. No Justice contended that the providers

possessed a statutorily created right. Why, then, go through all the rigmarole? At the

least, some Justice could be expected to explain why no one simply stopped the analysis

after noting that the providers did not claim to have a statutorily created right. In

particular, if the dissenters believed that the precedents relied on in the panel opinion

required a statutorily created private right to bring an equitable preemption action, surely

they would have tried to explain why they thought the providers had a statutorily created

right or at least reconcile their disregard of that requirement with those precedents.1

       Perhaps the Supreme Court one day will impose the same requirement that the

majority in this case would impose before a party can obtain equitable injunctive relief on

the ground that a state law is preempted by federal law. But that is not the law today.

       Nevertheless, I agree with the majority that the plaintiffs are not entitled to an

injunction against the Colorado statute.

       The plaintiffs and intervenors argue that the licensing schemes of Colorado and

Pueblo County must be enjoined because their facilitation and promotion of sales of

  Because the opinions in Armstrong make it clear that current Supreme Court doctrine
does not require the plaintiff to have a federally created substantive right in order to bring
an equitable preemption action, I think it unnecessary to review the errors in the panel
opinion’s analysis of earlier Supreme Court opinions.
                                           8
marijuana are preempted by the Controlled Substances Act (CSA). That argument must

be examined, however, in light of the Constitution’s anticommandeering principle

established in Printz v. United States, 521 U.S. 898, 935 (1997), and New York v. United

States, 505 U.S. 144, 188 (1992). Under that principle, Congress may not “commandeer

the legislative processes of the States by directly compelling them to enact and enforce a

federal regulatory program.” New York, 505 U.S. at 161 (brackets omitted). The

Supreme Court in New York considered a challenge to a federal statute dictating state

regulation of the disposal of low-level radioactive waste. See id. at 149–54. It

recognized that “the Framers explicitly chose a Constitution that confers upon Congress

the power to regulate individuals, not States.” Id. at 166. The Court concluded that a

portion of the federal statute was unconstitutional because “even where Congress has the

authority under the Constitution to pass laws requiring or prohibiting certain acts, it lacks

the power directly to compel the States to require or prohibit those acts.” Id. The

anticommandeering principle was reaffirmed in Printz, which concerned a federal statute

requiring local law enforcement to conduct background checks on prospective handgun

purchasers. See 521 U.S. at 902. The Court held that “Congress cannot circumvent [the

prohibition of New York] by conscripting the State’s officers directly.” Id. at 935. In

other words, “[t]he Federal Government may neither issue directives requiring the States

to address particular problems, nor command the States’ officers, or those of their

political subdivisions, to administer or enforce a federal regulatory program.” Id.

       The plaintiffs concede, as they must, that under the anticommandeering principle

the federal government cannot compel a State to enforce the CSA, much less to pass laws

                                           9
prohibiting the same conduct prohibited by the CSA. What if a State decides to control a

drug, but not as forcefully as the CSA? At what point would the lack of “full

enforcement” constitute encouragement or promotion of federal crimes? Say state law

imposes only civil penalties, not criminal ones. One could argue that such legislation

“encourages” the use of the drug because those in the state can be confident that they will

not be subject to any criminal sanctions—the State will not impose them and the limited

resources of the federal government make it highly unlikely that it would prosecute.

What if the State decides to prohibit only the sorts of distribution of the drug that it

considers most damaging to society? It could, for instance, prohibit only distribution of

the drug for profit. Or it could prohibit sales by anyone other than heavily regulated

entities whose owners and managers are subject to stringent background checks to make

sure that they have no ties to smugglers, organized crime, etc. Such a law could be said

to promote or encourage use of the drug, but only if the State’s legal regime were to be

compared to a regime that criminally prohibits all sales of the drug. Federal law,

however, cannot compel the State to criminally prohibit any sales whatsoever, see New

York, 505 U.S. at 166, so it would be improper for us to compare the State’s legal regime

to such a baseline and conclude that the State’s regime unlawfully promotes or

encourages violations of the CSA.

       This is not to say, however, that whatever Colorado law is, it could not be

preempted by the CSA. The anticommandeering principle does not preclude the federal

government from prohibiting States from enacting legislation. See NCAA v. Governor of

N.J., 832 F.3d 389, 398–402 (3d Cir. 2016) (federal statute prohibiting licensing of sports

                                            10
betting). Some specific provisions of Colorado law may be preempted. The Colorado

Supreme Court has already held that the CSA preempts a provision requiring “law

enforcement officers to return medical marijuana seized from an individual later

acquitted of a state drug charge.” People v. Crouse, 388 P.3d 39, 40 (Colo. 2017). Or

perhaps state advertising could constitute aiding and abetting violations of the CSA. The

plaintiffs may have a good claim for injunctive relief against actions by Colorado that

command or exhort violations of the CSA. But they are seeking to throw out the entire

statutory scheme—without offering any guidance on how a court should draw the line

between violating the CSA and simply failing to enforce it. Their complaint does not

allege facts showing that they are entitled to the injunctive relief they seek.2

       Finally, the panel opinion addresses the court’s jurisdiction to hear the claims by

the States of Nebraska and Oklahoma as intervenors. But because the merits of their

claims fall with those of the plaintiffs, I need not address the jurisdictional issue. See

Carolina Cas. Ins. Co. v. Pinnacol Assur., 425 F.3d 921, 927–28 (10th Cir. 2005) (court

need not address constitutional standing of one plaintiff when the merits of an identical

  I note that the amicus brief of Law Professors in Support of the Respondent State of
Colorado and Affirmance suggests that the U.S. Department of Justice (DOJ) has the
exclusive authority to initiate preemption challenges under the CSA. I express no view
on the propriety of an injunction sought by the DOJ. That prospect seems remote,
however, since the DOJ could almost certainly accomplish as much by notifying the State
that it planned to commence criminal prosecutions of licensed dealers in Colorado unless
the State modified its licensing regime or other practices. Cf. James M. Cole,
Memorandum for all U.S. Att’ys, Guidance Regarding Marijuana Enforcement (August
29, 2013) (conditioning the DOJ’s nonenforcement policy on the “expectation that states
and local governments . . . will implement strong and effective regulatory and
enforcement systems”).
