2 Opinion of the Court 24-13581

Appeal from the United States District Court for the Middle District of Florida D.C. Docket No. 8:19-cv-01236-KKM-SPF

Before BRANCH, LUCK, Circuit Judges, and MORENO,* District Judge. BRANCH, Circuit Judge:

The False Claims Act (“FCA”) allows the Attorney General to bring civil suits against perpetrators of fraud against the government. This case involves another portion of the FCA—the qui tam provisions—which allow people, called relators, who have knowledge about fraud against the government to pursue a case against the perpetrator of the fraud.

Here, a relator brought an FCA suit against defendants that she alleged committed Medicare fraud, and the defendants moved for judgment on the pleadings or dismissal on the grounds that the qui tam provisions violated the Constitution’s Appointments Clause, Take Care Clause, and Vesting Clause. The district court granted the defendants’ motion and held that the qui tam provisions violate Article II’s Appointments Clause 1 because

District of Florida, sitting by designation. 1 The Appointments Clause of Article II of the Constitution provides that the

President “shall nominate, and by and with the Advice and Consent of the Senate, shall appoint . . . Officers of the United States.” U.S. Const. art. II, § 2, cl. 2.

24-13581 Opinion of the Court 3

relators qualify as officers of the United States and, as such, must be (but are not) presidentially appointed.

We disagree and hold that relators are not officers of the United States because they do not occupy a continuing position established by law. Accordingly, we join our sister circuits that have addressed this issue and hold that the qui tam provisions of the FCA do not violate the Appointments Clause. 2 Therefore, we vacate the district court’s order dismissing this case and remand for the district court to evaluate the defendants’ remaining constitutional arguments.

I. Procedural Background In 2019, Dr. Clarissa Zafirov brought this qui tam action under the FCA on behalf of the United States against her employer and related entities, Florida Medical Associates (d/b/a VipCare); Physician Partners, LLC; Anion Technologies, LLC; Freedom Health, Inc.; and Optimum Healthcare, Inc. Zafirov alleged that the defendants knowingly submitted false diagnosis codes to receive more money than they were entitled to from Medicare, a federal health insurance program. The parties litigated the case for several years until February 2024, when the defendants moved for judgment on the pleadings or dismissal of the case. The defendants

(en banc); United States ex rel. Taxpayers Against Fraud v. Gen. Elec. Co., 41 F.3d 1032, 1041 (6th Cir. 1994); United States ex rel. Kelly v. Boeing Co., 9 F.3d 743, 757–59 (9th Cir. 1993); United States ex rel. Stone v. Rockwell Int’l Corp., 282 F.3d 787, 804–05 (10th Cir. 2002).

4 Opinion of the Court 24-13581

argued that the qui tam provisions violated Article II’s (1) Appointments Clause because relators exercise significant federal authority in a continuing position without appointment by the President; (2) Take Care Clause because the President lacks sufficient supervision and control over relators who wield executive power; and (3) Vesting Clause because relators have the executive power to bring civil enforcement actions on behalf of the United States while the Constitution vests that power in the President alone. Although the United States declined to intervene in the case when it was first filed, it intervened after the defendants raised these constitutional challenges “for the limited purpose of defending the constitutionality of the qui tam provisions of the [FCA].”

The district court determined that the qui tam provisions violated the Appointments Clause, so it did not address the defendants’ Take Care Clause or Vesting Clause arguments. United States ex rel. Zafirov v. Fla. Med. Assocs., LLC, 751 F. Supp. 3d 1293, 1304 (M.D. Fla. 2024). The district court made three central findings in its Appointments Clause analysis. Id. First, it concluded that relators are officers of the United States. Id. To make that determination, the district court used the test from Lucia v. SEC, 585 U.S. 237 (2018), that differentiates between government officers and mere employees to whom the Appointments Clause does not apply. Zafirov, 751 F. Supp. 3d at 1306–07. The Lucia test states that an individual is an officer if he “exercise[s] significant authority pursuant to the laws of the United States” and “occup[ies] a ‘continuing’ position established by law.” Lucia, 585 U.S. at 245

24-13581 Opinion of the Court 5

(quoting United States v. Germaine, 99 U.S. 508, 511 (1879)). The district court held that relators’ civil enforcement authority constitutes “significant authority” because similar enforcement authority qualifies FEC commissioners and special prosecutors as government officers. Zafirov, 751 F. Supp. 3d at 1307–09. The district court also held that relators occupy a continuing position— an “office of relator.” Id. at 1313–17. The court reasoned that “the office of relator exists whether a person is appointed to that office or not, making that office ‘continuous and permanent.’” Id. at 1314. And, the district court stated, it does not matter that relators act for only a single case. Id. at 1314–15. Second, the district court was unpersuaded that historical examples of similar qui tam provisions from the founding era justify the FCA’s constitutionality. Id. at 1317–22. Third, it determined that Zafirov was not presidentially appointed, which the parties did not contest. Id. at 1304, 1322.

After finding that the qui tam provisions of the FCA violated the Appointments Clause, the district court dismissed the case because Zafirov was “the only litigant on her side of the enforcement action” and lacked authority to prosecute on behalf of the United States. Id. at 1323.

We now turn to an overview of the relevant provisions of the FCA.

present[ing] . . . a false or fraudulent claim for payment or approval.” 31 U.S.C. § 3729(a)(1)(A). Also liable are those who “knowingly make[] [or] use[] . . . a false record or statement material to a false or fraudulent claim.” Id. § 3729(a)(1)(B).
