OPINION

_________________ 

DAVID M. LAWSON, District Judge. When Colonel David Antoon (United States Air 

Force, retired) learned that he needed prostate surgery, he researched treatment options and 

specialists, which led him to the Cleveland Clinic and defendant Dr. Jihad Kaouk. Col. Antoon 

interviewed Dr. Kaouk and arranged for him to perform the operation, or so he thought. When 

Col. Antoon experienced complications following the surgery, his further investigation caused 

him to suspect that Dr. Kaouk did not actually perform the surgery, and passed off the major 

duties to a surgical resident. Based on that suspicion, Col. Antoon lodged complaints with 

several individuals and agencies, and he filed a medical malpractice action in state court, which 

was dismissed voluntarily. Finding no satisfaction, Col. Antoon brought the present lawsuit as a 

relator under the qui tam provisions of the False Claims Act (FCA), premised on the theory that 

Dr. Kaouk billed the government for work he did not perform, and promoted the robotic surgical 

device he recommended in violation of the anti-kickback statute. The United States declined to 

intervene, and the district court granted the defendants’ motion to dismiss, after denying Col. 

Antoon leave to file a second amended complaint. Although we do not necessarily agree with 

some of the district court’s grounds for dismissing the case and declining the amendment, we do 

find that Col. Antoon cannot maintain a false claims action against the defendants because of a 

jurisdictional bar. Col. Antoon does not have any direct and independent knowledge of the 

information upon which his fraud allegations are based; therefore he cannot qualify as an original 

source of that information, and cannot establish standing as a qui tam plaintiff under the FCA. 

On that basis, we affirm the judgment of the district court. 

I. Facts and proceedings 

Col. Antoon began this action by filing a pro se complaint under seal in the district court 

on behalf of himself and his wife. He followed that with an amended complaint. After the 

government declined to intervene and the lawsuit was served, the defendants filed a motion to 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 3

dismiss under Federal Rule of Civil Procedure 12(b)(1) and (6). Col. Antoon then obtained 

counsel, who responded to the motion and moved for leave to file a second amended complaint. 

A. First amended complaint 

In the first amended complaint, Col. Antoon alleged that he met with Dr. Kaouk on 

December 6, 2007 to discuss surgical options to treat prostate cancer. At that meeting, Dr. 

Kaouk informed him that “robotic surgery was the safest surgical option and provided the best 

surgical outcomes for continence and potency.” Moreover, Dr. Kaouk represented that “only he, 

not doctors in training, would perform [Col. Antoon’s] major surgery.” Col. Antoon purportedly 

added language to the informed consent document that only Dr. Kaouk was authorized to 

perform the plaintiff’s surgery. 

On January 8, 2008, Col. Antoon underwent surgery, which resulted in multiple 

permanent complications causing disability and loss of employment. Col. Antoon alleges that he 

“did not see Jihad Kaouk in the operating room,” and told a surgical resident, Dr. Raj Goel that 

only Dr. Kaouk was authorized to perform his surgery. Dr. Goel called Dr. Kaouk twice from 

the operating room to express Col. Antoon’s concerns and then directed surgery to proceed over 

Col. Antoon’s objections. Dr. Kaouk called Ms. Antoon over the phone to say he “had trouble” 

and “got stuck,” apparently in an effort to explain the lengthy surgery. 

On January 15, 2008, Col. Antoon returned to the hospital for post-surgery procedures. 

A physician’s assistant removed Col. Antoon’s surgical drain and catheter, but no physician or 

resident met with him. Col. Antoon alleged that he “began experiencing multiple complications” 

after the visit, which he communicated to Dr. Kaouk, but were not documented in his chart. 

Since July 2009, Col. Antoon alleged that he lodged complaints with the Cleveland 

Clinic Foundation (CCF), the Ohio Department of Health, the State Medical Board of Ohio, the 

federal Centers for Medicare/Medicaid Services (CMS), the Joint Commission on Accreditation, 

and government insurance programs TRICARE and the Civil Health and Medical Program of the 

Uniformed Services (CHAMPUS). He submitted multiple Freedom of Information Act (FOIA) 

requests to state and federal agencies. He also filed a medical malpractice action in the 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 4

Cuyahoga County, Ohio Court of Common Pleas. Other former patients of Dr. Kaouk contacted 

the plaintiff after a newspaper article was published about Col. Antoon’s civil complaint. 

The CCF ombudsman, Daniel DiCello, investigated Col. Antoon’s complaint and 

concluded that there was “no indication that anything was done outside of the standard of care.” 

The ombudsman confirmed that “Staff Surgeon #16 [Jihad Kaouk] performed all critical points 

of the surgical procedure, consistent with the information provide[d] to the patient prior to 

surgery” and “the surgical fellow [Raj Goel] was limited to non-critical points of the surgical 

procedure, as [is] typically the case with procedures of this type.” But Col. Antoon insisted that 

CCF’s findings were “false and intentionally misleading.” Col. Antoon maintained that many 

records, documents, and communications were concealed, disappeared, or redacted to conceal 

complications from the surgery. 

The amended complaint states a single claim under the FCA; it appears that Col. 

Antoon’s theory was that CCF and Dr. Kauok violated several provisions of the TRICARE 

manual when submitting the bill for Col. Antoon’s prostate surgery. The essence of the false 

claim was the submission of a CMS-1500 claim form for surgery by Dr. Kauok, when in truth 

the surgery was performed by an unsupervised surgical resident. The relators also alleged that 

Dr. Kauok, the CCF, and device manufacturer Intuitive violated the Medicare and Medicaid 

Patient Protection Act by falsely promoting the efficacy of the robotic surgical device Dr. Kauok 

recommended when the doctor received compensation from Intuitive. Presumably, they meant 

to cite the anti-kickback provision in 42 U.S.C. § 1302a-7b(b)(2). The relators made similar 

claims against the other defendants. 

B. Proposed second amended complaint 

The proposed second amended complaint, which was rejected by the district court on 

futility grounds, was considerably more detailed; it spanned 116 pages, contained 

569 paragraphs, and included over 700 exhibits. But the theory of liability was the same: the 

defendants violated a condition of payment under the TRICARE and CHAMPUS programs 

when they submitted a CMS-1500 claim form and certified that the surgery was performed 

personally by Dr. Kaouk. The condition of payment was found in the TRICARE reimbursement 

manual. The plaintiffs alleged that several medical records do not indicate that Dr. Kaouk was 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 5

present for the surgery or that the records were altered or signed weeks after the surgery to cover 

up multiple investigations for fraud. The second amended complaint would have added 26 state 

law claims as well. 

The second amended complaint elaborated on Col. Antoon’s experience in the operating 

room. He says that he met with an anaesthesiologist around noon to discuss the risks and 

benefits of anesthesia. Thereafter, Dr. Goel, a resident urologist, entered the room and called Dr. 

Kaouk. Col. Antoon was taken to the operating room shortly before 1:00 p.m. He asked Dr. 

Goel why Dr. Kaouk was not present. Dr. Goel stated that Kaouk was in another surgery, but 

would arrive shortly. Goel stated to the anesthesiologist “Let’s get going! We are late.” Col. 

Antoon was under anesthesia from 1:05 p.m. until 5:20 p.m; the surgery began at 1:45 p.m. and 

concluded at 4:47 p.m. Col. Antoon “never saw Kaouk” prior to the anesthesia or in recovery. 

Col. Antoon’s wife, Linda Antoon, told her husband that Dr. Kaouk “paged her to a 

telephone to inform her that he had ‘trouble’ and ‘got stuck.’” Dr. Kaouk met with Col. Antoon 

the next day and informed him that “it took him more time to get the bowel adhesion down, 

because there was a lot of adhesions, and that he needed the extra 40 minutes to get all the bowel 

adhesions out of the way.” Dr. Kaouk expected a full recovery. However, during a meeting in 

December 2008, Dr. Kaouk said that Col. Antoon did not have adhesions and that Dr. Kaouk 

“probably placed clamps on his nerves.” 

In the proposed second amended complaint, the Antoons alleged that the CMS-1500 

claim form Dr. Kaouk submitted contained a legend below Dr. Kaouk’s signature stating: “I 

certify that the statements on the reverse apply to this bill and are made a part thereof.” The 

reverse side of the CMS-1500 form stated: 

I certify that the services shown on this form were medically indicated and 

necessary for the health of the patient and were personally furnished by me or 

were furnished incident to my professional service by my employee under my 

immediate personal supervision, except as otherwise expressly permitted by 

Medicare or CHAMPUS regulations. 

The Antoons also elaborated on their conversation with CCF Ombudsman DiCello. They 

alleged that on July 27, 2009, DiCello called the Antoons and told them that “resident Lee . . . 

had no recollection of Kaouk being present in Antoon’s surgery” and that “customarily, Kaouk 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 6

would only be present during the ‘nerve sparing portion of the surgery.’” “No findings were 

discussed other than the assertion by DiCello that Antoon authorized doctors in training to do his 

surgery and he accepted such risk.” Shortly thereafter, Col. Antoon sent DiCello an email asking 

“[a]t what point in my surgery did Kaouk arrive?” On August 4, 2009, Antoon received a letter 

from DiCello stating that the internal review was complete and Antoon’s medical care was 

appropriate and within the standard of care for such surgeries. 

The Antoons alleged that on October 31, 2009, Dr. Thomas Cook, an orthopedic surgeon, 

informed Col. Antoon that a surgeon is not allowed to bill for services unless present for the 

critical procedures. Col. Antoon asked Dr. Cook which portions of a radial prostatectomy are 

considered critical and Cook responded, “almost the entire surgery.” 

On November 16, 2009, Dr. Jack Pence, a urologist, reviewed Col. Antoon’s surgical 

records and concluded that Col. Antoon’s negative outcome was probably the result of an 

unsupervised resident doing his surgery. Pence stated that “it was common knowledge that 

multiple simultaneous surgeries were performed at Cleveland Clinic and other training hospitals 

by residents with a staff surgeon not present,” “he was aware of surgeons at the CCF allowing 

residents to do surgeries without patient knowledge or consent,” and “his last four penile implant 

procedures were on prostatectomy patients from CCF.” 

Col. Antoon also clarified that in addition to the complaints he lodged with the several 

agencies noted earlier, he tendered “41 FOIA submissions to CMS, 38 submissions to 

DOD/TRICARE, and 7 to HHS.” Several of those investigations revealed substantial violations 

related to medical records, surgical services, and staff credentials. The Antoons also alleged that 

after they filed their malpractice lawsuit and the Cleveland Plain Dealer published its article 

about the case, the “other victims of Dr. Kaouk” who contacted Col. Antoon said that they never 

saw Dr. Kaouk during their surgeries. 

C. Proceedings in the district court 

After the Antoons filed their lawsuit under seal, and after the United States declined to 

intervene, the district court ordered service on the defendants and portions of the record 

unsealed. The defendants filed motions to dismiss under Federal Rules of Civil Procedure 8(a), 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 7

9(b), 12(b)(1), and 12(b)(6), arguing that the district court lacked subject matter jurisdiction and 

the amended complaint failed to state a claim upon which relief could be granted. 

In granting the motion to dismiss and refusing leave to file the second amended 

complaint, the district court held that (1) the amended complaint did not state a claim under the 

FCA because it did not satisfy Rule 9(b)’s particularity requirement where it did not identify the 

services that Col. Antoon received, the specific claim form submitted for those services, and the 

date the claim forms were submitted; (2) the amended complaint did not contain sufficient facts 

to allege a fraudulent scheme because it did not allege that the defendants submitted any claims 

that were factually false, i.e., that Dr. Kaouk did not provide any medical services; and (3) the 

relators did not cite a condition of payment that would be violated if Kaouk was not present 

during the operation, because the TRICARE reimbursement manual did not constitute a law or 

regulation, which is what the FCA required. 

The district court also held that it lacked subject matter jurisdiction over the FCA 

allegations against Intuitive, Dr. Kaouk, and the Cleveland defendants because there was public 

disclosure of the Antoons’ allegations before they filed their FCA complaint in federal court, and 

they could not allege plausibly that they were an original source. The district court observed that 

facts concerning Dr. Kaouk’s financial arrangement and his practice of providing unreasonably 

optimistic descriptions of surgery outcomes with the robotic device were already in the public 

domain before the lawsuit was filed. Also, the Antoons made allegations in their June 2010 

malpractice lawsuit about Dr. Kaouk’s absence from the actual surgery. The court rejected the 

Antoons’ argument that they provided fresh information to the Centers for Medicare/Medicaid 

Services (CMS), because the amended complaint did not actually say that, and it appeared that 

the fraud allegations were based on information received from CMS. Moreover, the court held, 

disclosure to CMS does not satisfy the FCA’s requirement of disclosing information to the 

government; disclosure must be made to the Department of Justice (DOJ), and there were no 

factual allegations in the amended complaint or proposed second amended complaint that the 

Antoons made a disclosure to the DOJ. 

Finally, the court held that the amended complaint did not state a claim for a violation of 

the anti-kickback statute because the parts of that statute cited in the amended complaint are 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 8

criminal provisions and may only be enforced by the government; and even if the Antoons could 

bring the claim, the factual allegations were insufficient to state a claim. The court also denied 

leave to amend because the proposed second amended complaint did not cure the defects in the 

FCA claims, and the court would have declined to exercise supplemental jurisdiction over the 

remaining state-law claims. 

II. Discussion 

Although we do not necessarily agree with some of the district court’s rulings based on 

Rule 12(b)(6), the success of this case for the Antoons boils down to the question of subject 

matter jurisdiction, which was addressed by the defendants’ motion under Rule 12(b)(1). We 

give fresh review to a district court’s dismissal of an FCA complaint for lack of subject matter 

jurisdiction. Russell v. Garrard, 83 F. App’x 781, 782 (6th Cir. 2003) (per curiam) (citing 

Duncan v. Rolm Mil-Spec Computers, 917 F.2d 261, 263 (6th Cir. 1990)). 

Some of the defendants’ challenges address the substance of the fraud allegations and 

attack the merits of the relators’ claims. We have warned that attacks on the merits should not be 

confounded with jurisdictional challenges, admonishing courts to be more exacting when 

addressing arguments styled as jurisdictional attacks. Primax Recoveries, Inc. v. Gunter, 433 

F.3d 515, 518-19 (6th Cir. 2006) (“‘Clarity would be facilitated . . . if courts and litigants used 

the label “jurisdictional” not for claim-processing rules, but only for prescriptions delineating the 

classes of cases (subject-matter jurisdiction) and the persons (personal jurisdiction) falling within 

a court’s adjudicatory authority.’” (quoting Eberhart v. United States, 546 U.S. 12, 16 (2005) 

(per curiam), and citing Kontrick v. Ryan, 540 U.S. 443, 453 (2004))). 

However, although it is obvious that Col. Antoon’s main grievance stems from his belief 

that he received poor medical care, or perhaps that he was deprived of the benefit of his bargain 

(he hired the seasoned pro but believes he got the untested rookie instead), the actual victim of 

the federal claim he seeks to advance is the United States. Under the FCA, it is illegal to present 

a false claim for payment to the government. 31 U.S.C. § 3729(a)(1). The qui tam provisions of 

the Act grant standing to a limited class of private individuals to bring such claims. See United 

States ex rel. Dick v. Long Island Lighting Co., 912 F.2d 13, 18 (2d Cir. 1990) (“‘[T]he purpose 

of the qui tam provisions of the False Claims Act is to encourage private individuals who are 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 9

aware of fraud being perpetrated against the Government to bring such information forward.’”) 

(quoting H.R.Rep. No. 99-660, at 22 (1986)); see also United States ex rel. May v. Purdue 

Pharma L.P., 737 F.3d 908, 912 (4th Cir. 2013) (noting that the qui tam provisions of the FCA 

“statutorily vests private citizens with standing” (citing Vt. Agency of Natural Res. v. United 

States ex rel. Stevens, 529 U.S. 765, 773 (2000))). To establish standing, Col. Antoon must 

plead facts in his complaint that demonstrate that he satisfies the FCA’s qui tam requirements. 

See United States ex rel. Poteet v. Medtronic, Inc., 552 F.3d 503, 515-16 (6th Cir. 2009) 

(reiterating that “for a qui tam relator to have standing to bring her claim, she ‘must be a true 

“whistleblower”’” (quoting United States ex rel. Taxpayers Against Fraud v. General Elec. Co., 

41 F.3d 1032, 1035 (6th Cir.1994))). If he cannot meet those requirements, then he does not 

have standing and the federal courts do not have subject matter jurisdiction over his FCA claim. 

Loren v. Blue Cross & Blue Shield of Mich., 505 F.3d 598, 607 (6th Cir. 2007) (“As the party 

invoking federal jurisdiction, Plaintiffs bear the burden of establishing standing. If Plaintiffs 

cannot establish constitutional standing, their claims must be dismissed for lack of subject matter 

jurisdiction.”) (internal citations omitted); Zurich Ins. Co. v. Logitrans, Inc., 297 F.3d 528, 534 

(6th Cir. 2002) (Gilman, J., concurring) (“Without Article III standing, the district court lacked 

subject matter jurisdiction over the entire case. Where jurisdiction does not exist, ‘the only 

function remaining to the court is that of announcing the fact and dismissing the cause.’”); Ward 

v. Alternative Health Delivery Sys., Inc., 261 F.3d 624, 626 (6th Cir. 2001) (“Standing is thought 

of as a ‘jurisdictional’ matter, and a plaintiff's lack of standing is said to deprive a court of 

jurisdiction.”) (citations omitted). 

One of those requirements is that when the basis of the lawsuit has been publically 

disclosed in advance, the person filing the action must be the original source of the information 

that a false claim has been presented. Poteet, 552 F.3d 503, 507 (6th Cir. 2009) (stating that 

there is no “federal jurisdiction” under the “FCA [for] actions ‘based on the public disclosure of 

allegations or transactions . . . unless the action is brought by the Attorney General or the person 

bringing the action is an original source of the information.’” (quoting 31 U.S.C. § 3730(e)(4)(A) 

(2005)). After a public disclosure of the basis of the lawsuit, if a qui tam relator cannot establish 

himself as an original source of the information, he has no standing to proceed with the action. 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 10

The “original source” requirement in effect when the claim arose is jurisdictional. Rockwell 

Intern. Corp. v. United States, 549 U.S. 457, 467-68 (2007). 

A. 2010 amendments to the FCA 

Before we address the CCF defendants’ public disclosure bar arguments, we must 

determine which version of the statute applies to this case. The events described in the 

complaint occurred in 2007 and 2008. Congress amended the FCA in March 2010 and modified 

several aspects of the public disclosure bar, including the definition of “original source” in 

section 3730(e)(4)(B). There is no indication that the statute was meant to have retroactive 

effect, which would be necessary to apply it to conduct that occurred before the amendment. See 

Hughes Aircraft Co. v. United States ex rel. Schumer, 520 U.S. 939, 946 (1997) (holding that the 

presumption against retroactivity must apply “unless Congress has clearly manifested its intent to 

the contrary”); see also Landgraf v. USI Film Prods., 511 U.S. 244, 265 (1994) (observing that 

“the principle that the legal effect of conduct should ordinarily be assessed under the law that 

existed when the conduct took place has timeless and universal appeal” (internal quotation marks 

omitted)). The Supreme Court has held on two occasions that the 2010 FCA amendments do not 

apply to cases arising before the effective date of the statute. Schindler Elevator Corp. v. United 

States ex rel. Kirk, --- U.S. ---, 131 S.Ct. 1885, 1889 n.1 (2011); Graham Cnty. Soil & Water 

Conservation Dist. v. United States ex rel. Wilson, 559 U.S. 280, 283 n.1 (2010) (“The 

legislation makes no mention of retroactivity, which would be necessary for its application to 

pending cases given that it eliminates petitioners’ claimed defense to a qui tam suit.”). Other 

circuit courts that have considered the question have applied the pre-2010 version of the statute 

to such cases. See May, 737 F.3d at 918; United States ex rel. Zizic v. Q2Administrators, LLC, 

728 F.3d 228, 232 n.3 (3d Cir. 2013); United States ex rel. Goldberg v. Rush Univ. Med. Ctr., 

680 F.3d 933, 934 (7th Cir. 2012); United States ex rel. Jamison v. McKesson Corp., 649 F.3d 

322, 326 n.6 (5th Cir. 2011); United States ex rel. Poteet v. Bahler Med., Inc., 619 F.3d 104, 107 

n.2 (1st Cir. 2010); United States ex rel. Hixson v. Health Mgmt. Sys., Inc., 613 F.3d 1186, 1188 

n.3 (8th Cir. 2010). In May, the Fourth Circuit thoroughly analyzed the changes to section 

3730(e)(4) wrought by the 2010 amendments and concluded that “the 2010 version of the publicdisclosure bar cannot be applied in [that] case, notwithstanding the fact that the complaint was 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 11

filed after the effective date of the amendments.” May, 737 F.3d at 918 (citation omitted). We 

agree and hold that the pre-2010 version of section 3730(e)(4) applies in this case. 

B. Original source 

A relator cannot establish qui tam status if the “action under . . . section [3730 is] based 

upon the public disclosure of allegations or transactions in a criminal, civil, or administrative 

hearing, in a congressional, administrative, or Government Accounting Office report, hearing, 

audit, or investigation, or from the news media” unless the relator “is an original source of the 

information.” 31 U.S.C. § 3730(e)(4)(A) (1986). Congress has defined an “original source” as 

an individual who has direct and independent knowledge of the information on 

which the allegations are based and has voluntarily provided the information to 

the Government before filing an action under this section which is based on the 

information. 

31 U.S.C. § 3730(e)(4)(B) (1986). The district court held that the relators did not qualify as an 

original source because they did not disclose their information to a Department of Justice 

official. On appeal, the CCF defendants also argue that the relators did not have personal 

knowledge of the fraudulent conduct. The relators challenge both conclusions on appeal, as well 

as the conclusion that a public disclosure occurred. 

1. Public disclosure 

A public disclosure occurs “when enough information exists in the public domain to 

expose the fraudulent transaction.’” United States ex rel. Jones v. Horizon Healthcare Corp., 

160 F.3d 326, 331 (6th Cir. 1998) (quoting United States ex rel. Springfield Terminal Ry. Co. v. 

Quinn, 14 F.3d 645, 654 (D.C. Cir. 1994)). There is enough information in the public domain if 

“‘the information is sufficient to put the government on notice of the likelihood of related 

fraudulent activity.’” Poteet, 552 F.3d at 512 (quoting United States ex rel. Gilligan v. 

Medtronic, Inc., 403 F.3d 386, 389 (6th Cir. 2005)). Public disclosure “includes documents that 

have been filed with a court, such as discovery documents and a plaintiff’s complaint,” ibid., 

even if the plaintiffs filed the documents themselves, United States ex rel. Jones v. Horizon 

Healthcare Corp., 160 F.3d 326, 333 (6th Cir. 1998). Public disclosure also includes responses 

to FOIA requests. Schindler Elevator, 131 S. Ct. at 1893. 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 12

Two types of disclosures are sufficient to put the government on notice of fraud. Poteet, 

552 F.3d at 512. First, “‘if the information about both a false state of facts and the true state of 

facts has been disclosed, we [will] find that there has been an adequate public disclosure because 

fraud is implied.’” Ibid. (quoting Gilligan, 403 F.3d at 389). Second, “if there has been a direct 

allegation of fraud, we will find a public disclosure because such an allegation, regardless of its 

specificity, is sufficient to put the government on notice of the potential existence of fraud.” 

Ibid. (citing Gilligan, 403 F.3d at 389). “Moreover, the information suggesting fraud need not 

even come from the same source as long as the different sources ‘together provide information 

that leads to a conclusion of fraud.’” Ibid. (quoting Gilligan, 403 F.3d at 390). 

Several aspects of the relators’ pleadings show that there was a prior public disclosure of 

fraud. First, the Antoons filed a state court complaint on June 6, 2010, nearly two years before 

they filed their federal court action, in which they alleged that “upon information and belief, Dr. 

Kaouk either was not present during Colonel Antoon’s surgery, or he merely observed while key 

aspects of the procedure were completed by Dr. Goel, Dr. Lee, or some other doctor-in-training.” 

Second, the Cleveland Plain Dealer published an article highlighting the Antoons’ allegations 

and referenced the CMS investigation that, among other things, reviewed whether Dr. Kaouk 

performed his surgery. Third, the amended complaint and proposed second amended complaint 

contain allegations that the Antoons learned from responses to FOIA requests. Not only are 

those allegations sufficient to put the government on notice of the likelihood of “related 

fraudulent activity,” Poteet, 552 F.3d 503 at 516, but the government (CMS) investigated 

whether Dr. Kaouk performed the surgery and concluded he had. 

Further, the relators’ qui tam complaint was “based upon” a prior disclosure of fraud 

because there was “‘a substantial identity . . . between the publicly disclosed allegations or 

transactions and the qui tam complaint.’” Id. at 514 (quoting Jones, 160 F.3d at 332). For 

instance, the state court complaint, noted above, accused Dr. Kaouk of being absent from or not 

personally performing the core surgical tasks. And at least some of the allegations in the federal 

pleadings about Dr. Kaouk’s surgery schedule and inaccuracies contained in Dr. Kaouk’s 

medical records are based on responses that the Antoons received from their FOIA requests. 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 13

Because there was a public disclosure, the Antoons cannot establish qui tam status unless they 

are an “original source.” 

2. Disclosure to the “Government” 

The district court held that the Antoons cannot be an original source because they did not 

disclose their information about the defendants’ fraud to a Department of Justice official. A 

relator must disclose evidence of fraud to the government before filing an action under the FCA. 

Jones, 160 F.3d at 334. “[T]his rule is necessary because one is not a true whistleblower unless 

she is responsible for alerting the government to the alleged fraud before such information is in 

the public domain.” Ibid. However, we have never held that disclosure to the government under 

31 U.S.C. § 3730(e)(4)(A) is limited to the Department of Justice. Instead, a relator satisfies the 

requirements of 31 U.S.C. § 3730(e)(4)(A) if he discloses the information to the federal 

government. Jones, 160 F.3d at 334-335; see also United States ex rel. Davis v. District of 

Columbia, 679 F.3d 832 (D.C. Cir. 2012) (disclosure to Inspector General of Dept. of Health and 

Human Services held to be sufficient disclosure to “the government”); Minn. Assoc. of Nurse 

Anesthetists v. Allina Health System Corp., 276 F.3d 1032, 1032 (8th Cir. 2002) (holding that an 

association of nurse anesthetists qualified as an original source because it voluntarily provided 

information to the local Medicare office before filing suit). The district court erred in concluding 

that the Antoons did not qualify as an original source because they directed their complaints to 

CMS rather than the Department of Justice. 

3. Direct and independent knowledge 

 An original source is “an individual: (1) with direct and independent knowledge of the 

information on which the allegations are based . . . .” Jones, 160 F.3d at 333 (citing 31 U.S.C. 

§ 3730(e)(4)(B) (1986)). Our cases have addressed the meaning of “direct and independent 

knowledge” only in passing. We first discussed what it takes to be an “original source” in 

United States ex rel. McKenzie v. BellSouth Telecommunications, Inc., 123 F.3d 935, 941 (6th 

Cir. 1997), where we assessed the competing interpretations of that term among the circuits. We 

adopted the D.C. Circuit’s approach in United States ex rel. Findley v. FPC-Boron Employees’ 

Club, 105 F.3d 675 (D.C. Cir. 1997), overruled on other grounds by United States ex rel. Davis 

v. District of Columbia, 679 F.3d 832, 838-39 (D.C. Cir. 2012), and held that a relator is an 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 14

original source if the relator informs the government of the allegations of fraud before those 

allegations are disclosed to the public. Id. at 942 (finding “difficult[y] . . . understand[ing] how 

one can be a ‘true whistleblower’ unless she is responsible for alerting the government to the 

alleged fraud before such information is in the public domain”). However, a relator is not 

required to have had a hand in the public disclosure of the allegations that make up the qui tam 

lawsuit. Ibid.

 In arriving at that conclusion, we observed that the meaning of “direct knowledge” is 

commonly “interpreted as ‘marked by absence of intervening agency,’” Id. at 941 (quoting 

United States ex rel. Stinson v. Prudential Ins. Co., 944 F.2d 1149, 1160 (3d Cir. 1991)); and 

“‘independent knowledge’ is not ‘dependant on public disclosure,’” ibid. (quoting Houck v. 

Folding Carton Admin. Comm., 881 F.2d 494, 505 (7th Cir. 1989)). We noted that the Findley

court defined “direct knowledge” to mean first-hand knowledge and “independent” to mean that 

the information known by the relator does not depend or rely upon the public disclosures, id. at 

942, although we had no occasion to adopt those definitions at the time. 

 However, that definitional question presents itself here, because much of the information 

of the fraud alleged by the Antoons was pieced together from their interpretation of the records 

they gathered and their suspicion generated by what Col. Antoon saw — or did not see — 

immediately before and after his surgery. The CCF defendants argue that a relator cannot have 

“direct knowledge” under section 3730(e)(4)(B) unless his knowledge is first-hand. 

 There is language in the opinions from some courts that supports that idea. In United 

States ex rel. Aflatooni v. Kitsap Physicians Servs., 163 F.3d 516 (9th Cir. 1998), for instance, 

the court held that the relator, a physician, was not an original source of alleged Medicare billing 

fraud because the information “stem[med] from suspicions he developed after talking with 

patients who had previously received medical services from [the defendants] and after reviewing 

the information contained in their medical records.” Id. at 523. The court looked to its own 

precedent, United States ex rel. Devlin v. State of California, 84 F.3d 358, 360 (9th Cir. 1996), in 

which it had held that the relator was not an original source of the alleged fraud because he 

learned of it from an insider who actually witnessed the record falsification, and told the relator 

about it. In both cases, the court contrasted the facts in Wang v. FMC Corp., 975 F.2d 1412 (9th 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 15

Cir. 1992), in which an engineer-relator was found to be an original source because, when he 

was called in to study a problem with a product sold to the government because “he saw [it] with 

his own eyes” and his knowledge was “unmediated by anything but [his] own labor.” Id. at 

1417. The court then concluded that second-hand information does not constitute “direct 

knowledge”; to be an original source, the relator “must show that he had firsthand knowledge of 

the alleged fraud, and that he obtained this knowledge through his ‘own labor unmediated by 

anything else.’” Aflatooni, 163 F.3d at 525 (quoting Devlin, 84 F.3d at 361). 

 However, there is nothing in the statutory text that limits “direct knowledge” to first-hand 

knowledge. And “we have never stated whether a relator must possess a certain nature and 

quantity of information in order to have ‘direct and independent knowledge’ of her allegations.” 

United States ex rel. Branhan v. Mercy Health Sys. of Sw. Ohio, 188 F.3d 510 (6th Cir. 1999) 

(table) (Clay, J., concurring in part and dissenting in part). “Congress did not prescribe by 

mathematical formulae the quantum or centrality of nonpublic information that must be in the 

hands of the qui tam relator for suits to proceed.” Springfield, 14 F.3d at 653. 

 Certainly, proof of first-hand knowledge of fraud is sufficient to establish direct 

knowledge. After all, “[t]he paradigmatic ‘original source’ is a whistleblowing insider” who is a 

“‘close observer[] or otherwise involved in the fraudulent activity.’” United States ex rel. 

Stinson, Lyons, Gerlin & Bustamante, P.A. v. Prudential Ins. Co., 944 F.2d 1149, 1154, 1161 (3d 

Cir. 1991) (quoting S. Rep. No. 345, at 4, reprinted in U.S. Code Cong. & Admin. News 5269). 

But first-hand knowledge is not a necessary component of direct knowledge. A relator may rely 

in part on research or on information already in the public domain. See Minn. Ass’n of Nurse 

Anesthetists, 276 F.3d at 1050 (“If the relator has direct knowledge of the true state of the facts, 

it can be an original source even though its knowledge of the misrepresentation is not firsthand.”); United Stated ex rel. Atkinson v. PA. Shipbuilding Co., 473 F.3d 506, 522-23 (3d Cir. 

2007) (“We decline to adopt a rigid rule that consultation with public documents automatically 

disqualifies a relator from being an original source. Some reliance on public records or 

information is acceptable and, indeed, it is hard to imagine that a non-insider could ever obtain 

original source status without at least some consultation of publicly available information.”) 

(citing United States ex rel. Grynberg v. Praxair, Inc., 389 F.3d 1038, 1053 (10th Cir. 2004)). 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 16

For instance, a relator may have direct (but not first-hand) knowledge of the billing practices of 

an institution, and uncover fraud only after consulting a public document that reveals that those 

practices are fraudulent. See Minn. Ass’n of Nurse Anesthetists, 276 F.3d at 1050. We believe, 

therefore, the better view is that “direct” knowledge is knowledge gained by the relator’s own 

efforts and not acquired from the labor of other people. See United States ex rel Stone v. 

Rockwell Int’l Corp., 282 F.3d 787, 799 (10th Cir. 2002); United States ex rel. Reagan v. E. Tex. 

Med. Ctr. Reg’l Healthcare Sys., 384 F.3d 168, 177 (5th Cir. 2004). The statute requires the 

relator to possess direct knowledge of the “information” upon which the fraud allegation is 

based. “On the basis of plain meaning . . . § 3730(e)(4)(B) does not require that the qui tam

relator possess direct and independent knowledge of all of the vital ingredients to a fraudulent 

transaction.” Springfield, 14 F.3d at 656-57; see also Reagan, 384 F.3d at 177 (“The plain 

meaning of the term ‘direct’ requires ‘knowledge derived from the source without interruption or 

gained by the relator’s own efforts rather than learned second-hand through the efforts of 

others.’”); Kennard v. Comstock Res., Inc., 363 F.3d 1039, 1044-45 (10th Cir. 2004) (“Our 

review of the relevant case law revealed no requirement that a relator be a corporate insider. 

Additionally, we can think of no valid reason for creating such a restriction.”). 

 Each case is different and must be analyzed to assess the degree of the relator’s original 

input into the facts disclosed to the government. As the court explained in Kennard v. Comstock 

Resources, Inc., 363 F.3d 1039 (10th Cir. 2004), 

A mere compilation of documents or reports already in the public domain will not 

allow a relator to qualify as an original source. However, a complete and 

thorough investigation of a fraud on the Government will likely necessarily 

involve some review of contracts, documents, or other information in the public 

domain. It is the character of the relator’s discovery and investigation that 

controls this inquiry. 

Id. at 1045; see also Atkinson, 473 F.3d at 522 (noting that “[t]he more obscure the records and 

the more significant the investigative input of the relator, the more likely it is that granting 

original source status will fulfill the FCA’s ‘twin goals of rejecting suits which the government is 

capable of pursuing itself, while promoting those which the government is not equipped to bring 

on its own’” (quoting Springfield, 14 F.3d at 651)). 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 17

 Applying these principles requires us to focus on the character of the information of 

which Col. Antoon had direct knowledge. He knew that Dr. Kaouk was not present in the 

operating room before his surgery or after he woke up in the recovery room, but he did not 

personally observe whether Dr. Kaouk performed his surgery. Nor did Col. Antoon personally 

observe Dr. Kaouk create fraudulent medical records or bill TRICARE for other surgeries that he 

alleges Dr. Kaouk did not perform himself. Col. Antoon contends that the allegations that CCF 

and Dr. Kaouk violated conditions of payment are based on his own observations and a review of 

his private medical records. He received a copy of those records on February 11, 2009, March 

11, 2010, and March 17, 2010 — in the case of some documents, years before he received any 

FOIA responses. The heart of the Antoons’ FCA claim appear to be based on his review of those 

records — which led him to believe that Dr. Kaouk did not perform his surgery — and the fact 

that Col. Antoon did not see Dr. Kaouk before or after he performed his surgery. 

 However, that information is not sufficient to constitute direct and independent 

knowledge within the meaning of 31 U.S.C. § 3730(e)(4)(B), because the conclusion that Dr. 

Kaouk was not personally involved in the surgery is largely speculative. “[T]he purposes of the 

Act would not be served by allowing a relator to maintain a qui tam suit based on pure 

speculation or conjecture.” Aflatooni, 163 F.3d at 526. “[M]ere suspicion that there must be a 

false or fraudulent claim lurking around somewhere simply does not carry [a relator’s] burden of 

proving that he is entitled to original source status.” United States ex rel. Vuyyuru v. Jadhav, 

555 F.3d 337, 353 (4th Cir. 2009). Although the Antoons suspect that CCF and Dr. Kaouk 

committed fraud, they do not have any direct and independent knowledge of the information 

upon which their allegations are based. Col. Antoon does not have any direct or independent 

knowledge of any of the essential elements of an FCA claim. He did not see whether Dr. Kaouk 

performed his surgery, did not observe Dr. Kaouk submit false claims, and has only suspicion 

that his medical records were altered. Moreover, although the Antoons “may have provided the 

initial impetus” for the CMS investigation, that fact does not support a conclusion that the 

Antoons qualify as an original source. Hafter, 190 F.3d at 1162. Although Col. Antoon suspects 

that Dr. Kaouk submitted a false claim, mere suspicion is insufficient to qualify Col. Antoon as 

an original source. 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 18

 Because Col. Antoon is not an original source of the information on which his complaint 

was based, the public disclosure bar deprived the district court of subject matter jurisdiction over 

this action. Dismissal of the amended complaint, therefore, was proper. And because the 

proposed amended complaint did not cure those defects, refusal to allow the amendment on 

futility grounds was proper. 

III. 

 For the reasons discussed above, the district court’s judgment of dismissal is 

AFFIRMED.

CONCURRENCE

_________________ 

JULIA SMITH GIBBONS, Circuit Judge, concurring. I agree with the result reached by 

the majority, but I differ in my analysis of the meaning of “direct and independent knowledge.” 

31 U.S.C. § 3730(e)(4)(B). The majority is correct that the records and experts relied upon by 

the Antoons could not support their knowledge of the fraud they alleged. Even assuming that the 

Antoons could rely completely on second-hand knowledge, the Antoons had at most, as the 

majority notes, a set of facts and inferences that gave them a “‘mere suspicion,’” Maj. Op. at 23 

(quoting United States ex rel. Vuyyuru v. Jadhav, 555 F.3d 337, 353 (4th Cir. 2009)), that fraud 

had occurred. But the Antoons’ complete reliance on “‘speculation or conjecture,’” id. (quoting 

United States ex rel. Aflatooni v. Kitsap Physicians Servs., 163 F.3d 516, 526 (9th Cir. 1998)), 

means that we need not fully answer the question of what sort of knowledge is “direct and 

independent” under § 3730(e)(4)(B).1

But since the majority addresses that question, I believe the better approach would hew 

more closely to that of the Findley court. In other words, “to be ‘direct,’ the information must be 

first-hand knowledge.” United States ex rel. Findley v. FPC-Boron Emps.’ Club, 105 F.3d 675, 

690 (D.C. Cir. 1997), abrogated on other grounds as recognized by United States ex rel. Davis v. 

District of Columbia, 679 F.3d 832, 837–39 (D.C. Cir. 2012). Certainly, a relator need not have 

first-hand knowledge of all of the information supporting his allegations, see United States ex 

rel. Springfield Terminal Ry. Co. v. Quinn, 14 F.3d 645, 656–57 (D.C. Cir. 1994), but he must 

have at least some first-hand knowledge of that information. See United States ex rel. Branhan 

v. Mercy Health Sys. of Sw. Ohio, 188 F.3d 510 (6th Cir. 1999) (unpublished table decision) 

(citing United States ex rel. McKenzie v. BellSouth Telecomms., Inc., 123 F.3d 935, 943 (6th Cir. 

1997), to hold that relator cannot be an original source without first-hand knowledge). As the 

Third Circuit has explained, “[s]ome reliance on public records or information is 

acceptable . . . . [but] courts must be mindful of suits based only on secondhand information, 

speculation, background information or collateral research.” United States ex rel. Atkinson v. 

 1

This is especially true since the class of claims governed by that language is finite and shrinking, see

31 U.S.C. § 3731(b), after the 2010 amendments to the original source definition. 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 20

PA. Shipbuilding Co., 473 F.3d 506, 522–23 (3d Cir. 2007) (emphasis added) (internal quotation 

marks omitted). The relator may have personal knowledge of the defendant’s business practices, 

for instance, but not of its representations to the federal government. See Minn. Ass’n of Nurse 

Anesthetists v. Allina Health Sys. Corp., 276 F.3d 1032, 1050 (8th Cir. 2002). 

A personal knowledge requirement seems to me a closer reading of the cases from our 

sister circuits. In fact, this is quite possibly what the Aflatooni and Vuyyuru courts meant when 

they dismissed the claims before them as founded on suspicion and conjecture. See Vuyyuru, 

555 F.3d at 352–53 (citing Rockwell Int’l Corp. v. United States, 549 U.S. 457, 474–75 (2007)) 

(holding that a doctor-relator could not establish direct knowledge of a hospital’s fraudulent 

billing after he “had withdrawn from practicing” there at the time of the alleged fraud); 

Aflatooni, 163 F.3d at 525 (equating direct knowledge with first-hand knowledge). When courts 

have defined “direct” as, say, “marked by the absence of intervening agency,” they have often 

applied this phrase to require some amount of first-hand knowledge. See, e.g., United States ex 

rel. Stinson, Lyons, Gerlin & Bustamante, P.A. v. Prudential Ins. Co., 944 F.2d 1149, 1160–61 

(3d Cir. 1991) (finding no direct knowledge where relator acquired information “through two 

intermediaries”); accord United States ex rel. Hafter v. Spectrum Emergency Care, Inc., 

190 F.3d 1156, 1162–63 (10th Cir. 1999); United States ex rel. Barth v. Ridgedale Elec., Inc., 

44 F.3d 699, 703 (8th Cir. 1995); see also United States ex rel. Reagan v. E. Tex. Med. Ctr. Reg’l 

Healthcare Sys., 384 F.3d 168, 178–79 (5th Cir. 2004) (“[B]y [relator’s] own admission, the 

knowledge that she brings to the case is almost entirely indirect—that is, based on research and 

review of public records, not . . . her own observation.”). This conclusion also comports with the 

“theme recurring through the legislative history [of the 1986 amendments] . . . to encourage 

persons with first-hand knowledge of fraudulent misconduct to report fraud. Congress sought to 

stop the ‘conspiracy of silence’ among employees of corporations engaging in fraud.” 

Prudential Ins. Co., 944 F.2d at 1154 (quoting S. Rep. No. 99-345, at 4 (1986), reprinted in 1986 

U.S.C.C.A.N. 5266, 5269); cf. Rockwell Int’l Corp., 549 U.S. at 475 (“Because Stone was no 

longer employed by Rockwell at the time, he did not know that the pondcrete was insolid . . . .” 

(emphasis added)). 
No. 13-4348 United States ex rel. Antoon, et al. v. Cleveland Clinic, et al. Page 21

In addition to aligning more closely with case law, a rule of some first-hand knowledge 

comports with the normal meaning of “direct” as applied to evidence. Direct evidence is 

testimony of a witness about what that witness personally saw or heard or did. Sixth Circuit 

Pattern Jury Instructions § 1.06(2) (West 2013); see also 1 Clifford S. Fishman & Anne T. 

McKenna, Jones on Evidence § 1:5 (7th ed. 2014). In other words, direct evidence is based on 

first-hand knowledge. The knowledge possessed by the Antoons is based on their investigation 

of records created and maintained by others, and this is not first-hand. To the extent they have 

first-hand knowledge, it does not extend to having witnessed Kaouk’s presence or absence 

during surgery or to the filing of any claims with the government. Because the Antoons do not 

qualify as an original source, I agree that their complaint must be dismissed.
