5.2 Implied Causes of Action

Updated 2013 by Rochelle Bobroff, 2015 by Jeffrey S. Gutman

The concept of a cause of action originated in the common law's forms of proceedings and was not based upon the federal Constitution or statutes. In 1938, the Federal Rules of Civil Procedure were adopted and the forms of proceeding were abolished. The term "cause of action" was intentionally not utilized. Instead, the rules substituted the concept of a "claim." This change was sought, in part, due to the perception that the forms of proceedings were inadequate to provide remedies for violations of substantive rights.1 Nevertheless, courts continue to require plaintiffs to demonstrate that they are entitled to sue to enforce a specific duty owed by the defendant.2 Thus, "the plaintiff must demonstrate both that the defendant's conduct was wrongful (inconsistent with a duty resting on the defendant) and that the plaintiff is within the category of persons entitled to judicial relief because of the wrongful conduct.”3

In the 1960s and early 1970s, the Supreme Court was receptive to implying a cause of action in the federal Constitution as well as federal statutes that lacked a private right of action.4 While these decisions have not been formally overruled, the Court is now highly reluctant to imply a cause of action for damages in the Constitution. Recently, in a case involving a constitutional claim for damages, the Court stated that "implied causes of action are disfavored."5 The Court has similarly imposed a nearly impossible standard for implying a cause of action in a federal statute, requiring a plaintiff to supply evidence of congressional intent to confer a right of action from the text and structure of a statute that does not expressly specify access to enforcement in the federal courts.6 However, if your client's claim is covered by one of the earlier Supreme Court cases holding that a statute contains an implied cause of action, the statute remains enforceable under the previously recognized implied cause of action. The Court is, however, much more willing to permit claims for injunctive and declaratory relief to determine whether state law conflicts with federal law under the Supremacy Clause of the Constitution.7

5.2.A. Implied Constitutional Causes of Action for Damages

In 1971, in Bivens v. Six Unknown Named Agents of Federal Bureau of Narcotics, the Supreme Court created a federal cause of action against federal officers for damages due to a violation of the Fourth Amendment’s prohibition on unreasonable searches and seizures.8 This cause of action is not based on an express or implied statutory authorization to sue, but rather is grounded in the Constitution. Such an action is often referred to as a “Bivens action,” a “cause of action arising directly under the Constitution,” or a “constitutional tort.” This section discusses the circumstances in which a Bivens action may be brought.

Bivens actions are not needed when a statute authorizes the relief sought. For example, Bivens actions are not necessary to sue for claims under the Tucker Act and the Federal Tort Claims Act, because those statutes authorize damages.9 In contrast, the Administrative Procedure Act does not authorize damages against persons acting under color of federal law, and therefore, Bivens actions are necessary to support a damage claim against individual federal actors for constitutional violations.

Although the Court has not overruled Bivens, recently the Court has disparaged Bivens and refused to extend it. In Correctional Services Corporation v. Malesko, the Court expressly limited Bivens actions to the narrow range of claims previously recognized, those arising under the Fourth, Fifth, and Eighth Amendments to the U.S. Constitution.10

5.2.A.1. Constitutional Torts

A Bivens action is a suit for damages against a federal actor who, acting in his or her individual capacity under color of federal law, is alleged to have violated the plaintiff’s constitutional rights. The claim is a judicially created mechanism to afford redress to plaintiffs who lack a statutory cause of action or an adequate statutory remedy, or both.11 The action may be removed to federal court at the discretion of the defendant and administrative remedies need not be exhausted before the claim is brought.12 Generally, the basic elements of a Bivens action are the following:

  1. the plaintiff has a constitutionally protected right under the Fourth, Fifth, or Eighth Amendments;
  2. the defendant, a federal official, violated that right;
  3. the plaintiff lacks a statutory cause of action, or an available statutory cause of action does not provide monetary compensation against the defendant;
  4. no “special factors” suggest that the court should decline to provide the judicial cause of action and remedy, and
  5. no appropriate immunity can be raised by the defendant.13

In Bivens, the Court implied a damage remedy under the Fourth Amendment against individual federal law enforcement officers who had allegedly arrested Bivens and searched his home without a warrant or probable cause, causing him mental suffering, humiliation, and embarrassment. At that time, the Federal Tort Claims Act did not provide a remedy.14 The Court created a federal remedy by implication, reasoning that a state court tort claim would not adequately redress the constitutional wrong suffered by Bivens because the state laws of trespass and invasion of privacy were not intended to remedy the harms that result from a federal agent’s abuse of authority.15

The Court extended the implied cause of action principle to Fifth Amendment claims in Davis v. Passman.16 The female plaintiff alleged that then-Congressman Passman violated her Fifth Amendment right to equal protection by replacing her with a man.17 Because Congress had excluded congressional employees from the reach of Title VII, the Court held that Davis had no other viable remedy, that a damage remedy was judicially manageable, and that Davis could, therefore, sue directly under the Fifth Amendment.18

In both Bivens and Davis, the plaintiffs had no other available remedy; it was, therefore, a question of “damages or nothing.”19 In each case, this factor weighed heavily in the Court’s decision to imply a cause of action. However, the Court subsequently created a Bivens action in a case in which the plaintiff clearly had a statutory cause of action and limited remedy under the Federal Tort Claims Act. In Carlson v. Green, the Court allowed a Bivens action under the Eighth Amendment by an asthmatic prisoner who died against individual federal prison officials who allegedly failed to give him needed medical attention.20 The Court decided that a Bivens action was available because Congress had explicitly stated its intent to allow both the Federal Tort Claims Act and Bivens actions to coexist as complements.21 Carlson marks the high-water mark for the Bivens cause of action; the Supreme Court has declined further invitations to extend Bivens.

5.2.A.2. The Limitations on Bivens

Although Bivens, Davis, and Carlson initially seemed to suggest that Bivens actions for constitutional violations would be broadly available to fill gaps in federal damage remedies, the Court subsequently refused to extend Bivens actions beyond the scope of those earlier cases. Presently, when Congress provides a statutory cause of action without expressly indicating its intent to allow Bivens actions as well (as was the case in the legislative history examined in Carlson), the Court is unlikely to imply a cause of action.

The Court began to limit Bivens in Bush v. Lucas, a suit by a NASA employee against his supervisor for damages for emotional distress and mental anguish.22 The plaintiff alleged that he had been demoted and his salary decreased in retaliation for exercising his First Amendment right to speak on a matter of public concern. Although the employee obtained reinstatement and full back pay through the civil service administrative process, that process did not allow damages for emotional distress or mental anguish. Acknowledging that “existing remedies do not provide complete relief for the plaintiff,” the Court nevertheless refused to create a Bivens action.23 The Court concluded that the policy question of whether an employee should be permitted to recover damages from an employer was more appropriately left to Congress.24 Because Congress did not provide for individual liability within the existing “elaborate” and “comprehensive” remedial civil service scheme, or elsewhere, the Court refused to create an implied right of action. The Court stated:

When Congress provides an alternative remedy, it may, of course, indicate its intent—by statutory language, by clear legislative history, or perhaps even by the statutory remedy itself—that the Court’s power should not be exercised. In the absence of such a congressional directive, the federal courts must make the kind of remedial determination that is appropriate for a common-law tribunal, paying particular heed, however, to any “special factors counseling hesitation” before authorizing a new kind of federal litigation.25

Bush treated the existence of a congressionally designed remedial scheme as a “special factor counseling hesitation” in the Court’s analysis of whether to imply a constitutional cause of action. This suggests that the more comprehensive the remedial scheme, the less willing the Court is to imply a Bivens action. Thus, the Court declined to imply a right of action in Chappell v. Wallace, a case seeking damages from superior military officers for violating a constitutional right to be free from racial discrimination.26 The Court deemed the existence of a separate, congressionally enacted, “comprehensive internal justice system to regulate military life” and “the unique disciplinary structure of the Military Establishment,” to be “special factors” weighing against an implied right of action.27 In United States v. Stanley, this unwillingness to create a Bivens action based on “special factors” was broadened to include any claims that “arise out of or are in the course of activity incident to service.”28

In 1988, the Court confirmed that it would not create a Bivens remedy when Congress provided other meaningful remedies unless Congress explicitly preserved a Bivens remedy. In Schweiker v. Chilicky, the Court refused to imply a cause of action under the Due Process Clause of the Fifth Amendment in favor of social security disability recipients whose benefits had been terminated in a continuing disability review.29 The plaintiffs sued federal and state officials responsible for the review. The plaintiffs alleged that the officials terminated the recipients in clear violation of the procedural requirements of the Fifth Amendment, a determination of impropriety that Congress apparently agreed with in its enactment of legislation to stop the terminations.30 However, in language that reinforced the presumption against Bivens actions unless Congress clearly provides for them, the Court stated:

In sum, the concept of “special factors counseling hesitation in the absence of affirmative action by Congress” has proved to include an appropriate judicial deference to indications that congressional inaction has not been inadvertent. When the design of a government program suggests that Congress has provided what it considers adequate remedial mechanisms for constitutional violations that may occur in the course of its administration, we have not created additional Bivens remedies.31

As one district court subsequently put it,“[i]t may safely be said, therefore, that the dictum of Carlson v. Green which urged the creation of constitutional torts unless Congress had provided a remedial scheme equivalent to Bivens and had expressly stated that the remedy was exclusive, is not good law.”32

In 2001, the Supreme Court decided Correctional Services Corporation v. Malesko, which, again, demonstrated the Court’s refusal to extend Bivens and, indeed, a potential willingness to confine it.33 In Malesko, the Court used strong language to reject a Bivens suit by a federal inmate against a private corporation that operated a halfway house under contract with the federal Bureau of Prisons. The Court referred to Bivens as a “limited holding” and noted that the Bivens Court’s exercise of its authority to imply a constitutional tort had relied heavily on J.I. Case Company v. Borak,34 a case it had since “abandoned.”35 The Court noted that, in the decades subsequent to Bivens, the Court had extended its holding only twice and that it had otherwise “consistently refused to extend Bivens liability to any new context or new category of defendants.”36

This language could be considered dicta because Malesko went on to emphasize that the defendant was a private corporation, for which Bivens actions were inapplicable. The Court compared the Malesko case to Federal Deposit Insurance Corporation v. Meyer, where it had refused to extend Bivens to permit suits against a federal agency whose sovereign immunity Congress had waived.37 In Meyer, the Court reasoned that a damages suit against a federal entity would not advance the core purpose of the Bivens remedy, which was to deter individual federal officers from committing constitutional violations.38 Similarly, the Malesko Court held that a Bivens action against a private entity would also lack deterrent effect for individual violations of the Constitution. Moreover, federal prisoners housed in private facilities enjoyed possible alternative remedies (such as state tort remedies) unavailable to inmates in government facilities. The Court asserted that a Bivens remedy had “never [been] considered a proper vehicle for altering an entity’s policy” rather, “injunctive relief has long been recognized as the proper means for preventing entities from acting unconstitutionally.”39

Thus, the Court had several bases for distinguishing the Malesko facts from the Bivens situation and could have reached its conclusion without using any of the strong limiting language quoted above. The Court’s decision to go out of its way to cabin the Bivens remedy within very narrow parameters signaled a refusal to extend Bivens to new constitutional claims. Indeed, the Court recently reaffirmed Malesko in a case seeking to imply and Eighth Amendment Bivens claim against a private correctional facility in Minneci v. Pollard.40 In Minneci, the Court found that the state tort law supplied a remedy for a prisoner alleging inadequate medical care and treatment and rejected the argument that the Court should look only to federal law, rather than the "vagaries" of state law to determine whether an adequate alternative remedy exists.41

In the 2009 case of Ashcroft v. Iqbal, the Court again expressed open hostility to extending Bivens. The case held that the allegations pled in the complaint were insufficient to support a claim of religious discrimination under the First Amendment. While Bivens was not central to the Court’s holding or reasoning, the Court downplayed Bivens, stating: “[b]ecause implied causes of action are disfavored, the Court has been reluctant to extend Bivens liability ‘to any new context or new category of defendants.’”42

Indeed, relying on the “special factor” language in Chilicky, courts no longer afford plaintiffs a Bivens remedy for violations of the Fourth, Fifth, and Eighth Amendments, even in the absence of an adequate statutory remedy, if such absence is deemed to reflect a Congressional intent to preclude Bivens actions.43 The Court itself has signaled the constriction of Bivens actions under these amendments unless the case closely resembles Bivens, Davis, or Carlson.44 In one of its most recent Bivens cases, the Court held in Wilkie v. Robbins that allegations by a ranch owner of organized efforts by federal officers to coerce an easement across his property did not constitute Fourth and Fifth Amendment violations for the purposes of a Bivens action.45 For the Wilkie Court, the existence of “alternative, existing process[es]” for protecting the infringed-upon interests of the ranch owner, counseled against inferring constitutional causes of action under either amendment.46 Furthermore, the Court held that “special factors” weighed against authorizing a Bivens action, specifically the complexity of the allegations.47 As a result, a Bivens claim in this case was not a “workable cause of action.”48

In essence, Bivens, Davis, and Carlson have been limited to their facts, and are unlikely to be extended, at least for the foreseeable future.49 While those cases remain good law, their applicability has been severely restricted. For fact patterns closely resembling those cases, therefore, courts may imply a cause of action under the Fourth Amendment right to be free from unreasonable searches and seizures, the Fifth Amendment Due Process Clause’s equal protection component, and the Eighth Amendment right to be free from cruel and unusual punishment.50

The Court has also clearly assumed, without so holding, the viability of Bivens claims under the First Amendment.51 The Court applied this assumption in Hartman v. Moore, where it held that a Bivens plaintiff who claimed that government employees violated his First Amendment rights by participating in a retaliatory criminal prosecution, must plead and prove the absence of probable cause underlying the criminal case.52 More recently, the Court repeated this assumption in Ashcroft v. Iqbal, stating that it was “assum[ing], without deciding, that [a] First Amendment claim is actionable under Bivens.”53 Thus, it remains possible to seek relief under Bivens for violations of the First Amendment as well.54

5.2.B. Implied Private Statutory Causes of Action

As discussed earlier in this Chapter, many federal statutes expressly provide a right for injured individuals to sue to enforce the law. When an express right specific to a particular statute is unavailable, advocates must determine whether a claim may be brought under the general authority of statutes such as the Administrative Procedure Act or 42 U.S.C. § 1983. Those statutes, of course, have their limitations, including a failure to extend to private parties who are not state actors. Consequently, advocates may need to inquire whether a private right of action may be implied in a particular federal statute. As explained below, beginning in the mid-1970s, the Supreme Court sharply constricted the availability of implied private rights of action for federal statutes and further restricted the enforceability of federal regulations in the 2001 case of Alexander v. Sandoval.55

5.2.B.1. Limitation of an Implied Private Right of Action to Enforce Federal Statutes

In the late 1960s, the Supreme Court held that private individuals could enforce federal anti-discrimination statutes to remedy explicit racial discrimination, based on an implied statutory cause of action.56 These decisions focused on the need to provide a remedy to correct racial injustice when a federal statute establishes the right to be free from racial discrimination.

In 1975, in Cort v. Ash, the Court, however, unanimously limited the use of implied statutory causes of action.57 In an opinion by Justice Brennan, the Court set forth a four-prong test for finding an implied cause of action. The test asks whether 1) the plaintiff is in the class for whose especial benefit the statute was enacted; 2) there is any indication of legislative intent, explicit or implicit, either to deny or to create a private right to enforce; 3) a private right to enforce would be consistent with the underlying purpose of the statute; and 4) the cause of action is traditionally in the purview of state law, such that a federal right to enforce would be inappropriate.58 The holding of the case was that there was no implied cause of action in the Federal Election Campaign Act for stockholders to obtain damages from corporate directors, because none of the four factors were met.

In Cannon v. University of Chicago, decided in 1979, the plaintiff alleged that she was denied admission to medical school based on her gender, in violation of Title IX of the Education Amendments of 1972. The Court found that Title IX met all four of the Cort v. Ash prongs.59 With regard to legislative intent, the Court reasoned that in drafting Title IX, Congress relied upon the Court's cases from the late 1960s which had implied a cause of action in statutes designed to remedy racial discrimination, such as the Voting Rights Act. Title IX was also modeled on Title VI of the Civil Rights Act of 1964, which prohibits racial discrimination by recipients of federal funds, and had been found enforceable under an implied private right of action by numerous courts of appeals.60 Therefore, the Court concluded that Congress had intended Title IX to be privately enforceable. The Court also stated that it was "decidedly receptive" to an implied cause of action that was helpful to the statutory purpose.61 However, the Court cautioned Congress against future reliance on the implied cause of action cases from the 1960s. Justice Stevens, writing the majority opinion, stated, "When Congress intends private litigants to have a cause of action to support their statutory rights, the far better course is for it to specify as much when it creates those rights."62

The availability of an implied private right of action was sharply narrowed in two cases decided just a few months later.  Without rejecting the four-part test, the Court interpreted the test as being most heavily focused on the second prong: evidence of congressional intent to create a private right.63 The Court looked for specific statutory language establishing a right to sue and to obtain damages.64 Since the statutes examined did not contain an express private right of action, there was no such language, leading the Court to conclude that the statutes did not contain an implied right of action. While citing Cannon with favor, the Court explicitly rejected the emphasis in Cannon and other prior cases on implying a private right in order to effectuate the purpose of the statute.65

In 1982, Justice Stevens authored an opinion finding an implied statutory right of action to enforce the Commodity Exchange Act.66 Stevens asserted that in earlier times, the common law supplied a remedy for an individual injured by the breach of a duty. Yet, he explained, the Court unanimously modified its approach in Cort v. Ash, due to the "increased complexity of federal legislation and the increased volume of federal litigation." Presently, the Court requires "more careful scrutiny of legislative intent" to imply a private right of action.67 Because the Commodity Exchange Act was amended in 1974, before the change in the Court's approach in the 1975 Cort v. Ash case, the majority found that "Congress intended to preserve the preexisting remedy" of an implied right of action. The Court concluded that the provision of new remedies in 1974 was "intended to supplement rather than supplant the implied judicial remedy."68  The Court specifically rejected the argument that the implication of a right of action violates separation of powers, noting that judicial implication of a right turns on congressional intent.69

A year later, the Court was asked to decide upon the standard of proof needed to prevail in a Title VI case, specifically whether proof of discriminatory intent was required to obtain compensatory relief.70 The Court splintered, producing six separate opinions.  Nevertheless, seven Justices accepted that, under the reasoning of Cannon, there was an implied private right of action to enforce Title VI.71

The Court has never overruled Cannon or cases based on it. As a result, claims under Title VI and Title IX remain enforceable under an implied private right of action. The Rehabilitation Act adopts the remedies of Title VI, and thereby also utilizes an implied private right of action.72  

Nevertheless, for statutes enacted after Congress was notified that the Court expected it to "specify" a cause of action, the Court has refused to permit enforcement of rights through an implied statutory cause of action.73 Lower court cases finding an implied private right of action in such statutes are therefore extremely vulnerable to challenge.  For instance, the Fifth Circuit held in 1981 that language in the Housing and Community Development Act similar to the language of Title IX is enforceable under a private right of action.74 That holding was explicitly rejected by several other courts, including the First Circuit.75

Thus, by 2000, numerous cases held there was no implied private right of action to enforce federal statutes, other than Title IX, Title VI, and the Rehabilitation Act, for which an exception had been carved out by the Supreme Court. Even before Alexander v. Sandoval greatly limited private enforcement of regulations, scholars proclaimed that obtaining relief for violations of rights in federal statutes under an implied private right of action was "foreclosed."76

5.2.B.2. The Conflation of the Implied Private Right of Action with the Express Right of Action in Section 1983

In Wright v. City of Roanoke Redevelopment and Housing Authority,77 Justice O'Connor wrote a dissent on behalf of four Justices which introduced the idea that the Cort v. Ash test for an implied right of action should be utilized in determining whether a plaintiff may access the express right of action in 42 U.S.C. § 1983. She suggested that each specific provision of the statute, not the statute as a whole, be carefully scrutinized to "determine congressional intent to create enforceable rights."78 This analysis imports into the § 1983 analysis the second prong of the Cort v. Ash test—a search for legislative intent to create a private right of action in a statute devoid of any express right to sue in federal court.

To the contrary, Justice Brennan subsequently argued in another 5-to-4 decision regarding § 1983 that an implied private right of action is completely different from the utilization of the express right of action in § 1983.79 Rather, he asserted that the Section 1983 remedy is available unless there is clear evidence of legislative intent to take away this express right of action. However, after Justice Brennan left the Court, Justice O'Connor's vision became law. In Gonzaga University v. Doe, the Court held that evidence of congressional intent to create enforceable rights is a prerequisite to utilization of § 1983.80 Gonzaga explicitly blurs the distinction between an implied right of action and the express right of action in § 1983.81

5.2.B.3. Sandoval Limits Enforceability of Federal Regulations

Alexander v. Sandoval involved a challenge to the Alabama Department of Safety’s refusal to administer its driver’s examination in a language other than English.82 The plaintiff was a Mexican immigrant who did not have the English skills necessary to take a written examination. She sued, arguing that the driver’s license rule violated the regulations implementing Title VI of the Civil Rights Act of 1964. Section 601 of Title VI forbids discrimination based on race or national origin in any program or activity receiving federal funds. Section 602 of the statute authorizes the federal government to promulgate regulations to implement Section 601. The regulations interpret national origin discrimination to include actions that did not intend to discriminate but had that effect because of factors having a disparate impact, such as an individual’s limited ability to speak English.

The Supreme Court in Sandoval found it “beyond dispute that private individuals may sue to enforce [Section] 601” of Title VI utilizing an implied private right of action.83 However, the Court interpreted Section 601 as applying only to intentional discrimination.  The Court limited Cannon to its facts, in which intentional discrimination was alleged to violate Section 601. The "disparate impact" regulations were found to be beyond the scope of Section 601's prohibition on intentional discrimination, and therefore not enforceable under Section 601. The Court stated, “[l]anguage in a regulation may invoke a private right of action that Congress through statutory text created, but it may not create a right that Congress has not.”84

The Court further rejected the plaintiffs' claim that Section 602, which authorizes regulations to implement Section 601, was enforceable utilizing an implied private right of action.85 In analyzing the implied right of action issue, the Court found the existence or absence of “rights-creating language” to be critical to the inquiry.86 Sandoval suggests that congressional intent to create private remedies is the determinative issue; that is, does the statute “display[] an intent to create not just a private right but also a private remedy?”87 Congressional intent is to be determined almost exclusively based on the text and structure of the statute. The Court expressed disdain for inferring remedies necessary to effectuate congressional purpose.88 The Court made clear that the statute's text and structure must evince a “congressional intent to create new rights.”89

In future cases involving regulations, advocates are best advised to seek enforcement of a statute, rather than regulations promulgated pursuant to the statute. In Jackson v. Birmingham Board of Education, for example, the Supreme Court reversed the Eleventh Circuit’s holding that Sandoval precluded enforcement of a Title IX regulation prohibiting retaliation.90 The Court held that Sandoval was irrelevant because such retaliation is prohibited by the statute’s text.91

Courts of appeal interpreting Sandoval, in conjunction with Gonzaga, have reversed their prior caselaw and have held that "regulations alone cannot create rights enforceable through either an implied right of action or [Section] 1983.”92   Nevertheless, if a right is conferred through the statute, then the regulations are relevant to the scope of the right conferred by Congress.93

Even for statutes with a private right of action, however, Sandoval places limits on the enforceability of accompanying regulations.  Refusing to enforce a regulation under the Americans with Disabilities Act, the Ninth Circuit stated that pursuant to Sandoval: "those regulations effectuating the statute's clear prohibitions or requirements are enforceable through the statute's private right of action; regulations that do not encapsulate the statutory right and corresponding remedy are not privately enforceable."94   Therefore, only regulations within the clear mandate of a statute with an express right of action remain enforceable and are not impacted by Sandoval.95

5.2.C. The Preemption Claim

Following the Court's limitations on implied rights of action under federal statutes and regulations in Cort v. Ash and its progeny and Alexander v. Sandoval (discussed supra, 5.2.B) and narrowed interpretation of Section 1983 in Gonzaga University v. Doe (discussed in Chapter 5.1.A), advocates have explored the use of preemption doctrine to enjoin state or local actions that conflict with federal statutes or regulations that do not contain an explicit right of action and that do not create rights enforceable under Section 1983.96

The notion is that preemption doctrine arises from the Supremacy Clause of the Constitution.97 If state statutes or actions are “inconsistent with an act of Congress, they are void, so far as that inconsistency extends.”98 A suit to enforce this preemption concept requires a cause of action. It was thought that such a cause of action could be implied from the Supremacy Clause itself.99  

The Supreme Court's recent decision in Armstrong v. Exceptional Child Center, Incorporated100 put an end to that idea. In Armstrong, providers of Medicaid-covered habilitation services sued officials in Idaho's Department of Health and Welfare on the ground that Idaho's Medicaid plan reimburses them at rates lower than required by a federal statute.101 Suing directly under the Supremacy Clause, the plaintiffs asked a federal court to enjoin the state plan.

Both the majority and the dissent agreed that the Supremacy Clause does not create a cause of action.102 In response to the argument that the Court had frequently enjoined state actors violating federal law, the Court responded that, because it had done the same with respect to federal actors, the Supremacy Clause cannot serve as the explanation.103 Instead, the Supremacy Clause merely provides a rule of decision in cases correctly raising preemption claims, instructing courts on what to do when state and federal law clash.

How, then, are Supremacy Clause claims properly brought before the court? While not identifying a basis for such a cause of action, the Court held that federal courts have equitable power "to enjoin unlawful executive action."104 That power, however, does not exist when Congress forecloses its use. In Armstrong, the majority and dissent quarreled over whether Congress did so, the majority holding that Congress foreclosed a court in equity from enjoining the state to extend Medicaid payment relief as requested by the health care providers. It offered two reasons. First, Congress' only statutory remedy for a state violation of federal Medicaid requirements was to authorize HHS to withhold federal funds. Second, while acknowledging that the withhold provision might not, by itself, preclude equitable relief, it did so when combined with what the Court found to be the broad and "judicially unadministrable" text of the Medicaid Act payment provision.105

Together, the Court reasoned, these factors reflected Congress' implicit intent to preclude health care providers' private enforcement of the Medicaid Act's payment provision. In so deciding, the majority rejected the dissent's view that congressional intent to foreclose private enforcement would need to be reflected affirmatively, rather than by implication, in the statute, because Congress was aware of the Court's long-standing practice of enjoining preempted state action and legislated against that background principle.106

Armstrong does not preclude preemption arguments, but it does preclude preemption claims based solely on the Supremacy Clause. Such arguments must be tied to another cause of action, such as those involving the court's equitable power to enjoin state laws and acts that conflict with federal law.107 However, that law can serve as a basis for such injunctive relief only when Congress has not precluded private enforcement. While Armstrong provides some guidance on when this may be so, and appears to draw from some of the prongs of Gonzaga analysis, future cases will explore these contours.
