Appeal from United States District Court 

for the Southern District of Iowa - Eastern

Before LOKEN, COLLOTON, and BENTON, Circuit Judges.

BENTON, Circuit Judge.

Plaintiffs Patrick M. Kearns and Jeffrey Dettbarn sued for various torts in 

Iowa state court against Dr. David Rideout, a radiologist at the Veterans Health 

Administration’s Medical Center in Iowa City, Iowa. The United States of America 

removed the case to federal court under the Federal Tort Claims Act, 28 U.S.C. §§ 

1346, 2671-80. The government moved for substitution as defendant. Plaintiffs 
-2-

opposed the motion. After limited discovery and briefing, the district court1

substituted the United States for Rideout as defendant, and later dismissed the case. 

Plaintiffs appeal the district court’s order granting substitution of defendants. 

Having jurisdiction under 28 U.S.C. § 1291, this Court affirms. 

I. 

David Rideout is a doctor and radiologist at the Medical Center in Iowa City, 

Iowa, a hospital within the Veterans Health Administration (VHA). Jeffrey 

Dettbarn, a radiological technologist at the Medical Center, worked with Rideout. 

Patrick Kearns, a registered nurse, was the president of Dettbarn’s union. In 2017, 

Dettbarn repeatedly refused to follow Rideout’s oral instructions about patient care, 

including instructions about how to position a patient, an initial request for help 

addressing a patient’s allergic reaction, and how to use patient forms to expedite 

treatment. Rideout viewed these instructions as within clinical treatment guidelines 

and hospital protocol. Dettbarn asserted these oral instructions deviated from 

protocol, which required a written order before he could comply, so he was not 

allowed to follow them under hospital policy until Rideout provided the written 

order. Around mid-June 2017, Rideout complained to a representative of Dettbarn’s 

union, who involved Kearns. Rideout then elevated his concerns to the Medical 

Center’s ethicist and higher-level managers. 

In mid-July 2017, Medical Center leadership addressed whether Dettbarn 

could refuse to follow instructions related to patient care. Rideout then reported his 

concerns about how Dettbarn’s behavior affected patient treatment to the Iowa 

Department of Public Health, and the national licensing body for radiological 

technologists. He similarly reported Kearns to the Iowa Board of Nursing. Rideout 

also reported his concerns to the VA’s executive officer for patient safety, and to a

Southern District of Iowa.
-3-

staffer for U.S. Senator Charles Grassley. In these communications, Rideout 

focused on how Dettbarn’s and Kearns’s behavior affected clinical patient treatment. 

Kearns and Dettbarn then sued Rideout in Iowa state court for various torts, 

including defamation, and interference with a business relationship. The 

government removed the case to federal court. It then moved to substitute itself for 

Rideout, certifying that Rideout’s conduct fell within the scope of his employment. 

After discovery and briefing, the district court reviewed the submitted evidence, 

concluded that an evidentiary hearing was unnecessary, ruled that Rideout acted 

within the scope of his employment, and substituted the government. The 

government later filed a motion to dismiss, which the court granted. 

Kearns and Dettbarn appeal the district court’s order substituting the 

government for Rideout. This Court reviews de novo the district court’s order 

granting substitution of the government. Wilcox v. United States, 881 F.3d 667, 

671 (8th Cir. 2018). 

II. 

The Federal Tort Claims Act (“FTCA”) provides the exclusive remedy for 

any injury “arising or resulting from the negligent or wrongful act or omission of 

any employee of the Government while acting within the scope of his office or 

employment.” 28 U.S.C. § 2679(b). In an FTCA suit, “the United States shall be 

substituted as the party defendant” “[u]pon certification by the Attorney General that 

the defendant employee was acting within the scope of his office or employment at 

the time of the incident out of which the claim arose.” Id. § 2679(d)(1). 

This certification, however, does not “conclusively establish that the United 

States should be substituted as party defendant.” Heuton v. Anderson, 75 F.3d 357, 

360 (8th Cir. 1996); Gutierrez de Martinez v. Lamagno, 515 U.S. 417, 434 (1995). 

If a plaintiff challenges the certification, “the district court must determine whether 

the defendant was acting within the scope of his employment when the conduct in 
-4-

question occurred.” Heuton, 75 F.3d at 360. The plaintiff “bears the burden of 

coming forward with specific facts rebutting the certification.” Lawson v. United 

States, 103 F.3d 59, 60 (8th Cir. 1996). “An evidentiary hearing should be held if 

there are material fact issues in dispute” regarding the scope of employment. 

McAdams v. Reno, 64 F.3d 1137, 1145 (8th Cir. 1995). See Brown v. Armstrong, 

949 F.2d 1007, 1012 (8th Cir. 1991) (requiring disputes be resolved “as soon after 

the motion for substitution as practicable, even if an evidentiary hearing is needed 

to resolve relevant fact disputes”). 

To assess whether material facts exist, a court should apply the genuine-issueof-material-fact standard used at summary judgment, interpreting the evidence in the 

light most favorable to the party opposing substitution. See, e.g., United States v. 

Hirani, 824 F.3d 741, 746 (8th Cir. 2016) (stating summary judgment standard). If 

an issue of material fact exists, the court should conduct an evidentiary hearing. 

McAdams, 64 F.3d at 1145. This is because briefing and evidence about a contested 

substitution is akin to summary judgment: just as the court would deny the summary 

judgment motion if a genuine issue of material fact exists and proceed to trial, the 

court here should proceed to an evidentiary hearing, where the court takes the role 

of fact-finder to resolve those issues of material fact. See Brown, 949 F.2d at 1011-

12 (stating FTCA substitution process sought to undue a Supreme Court decision 

and “return Federal employees” to the system in which “questions of official 

immunity were resolved through a summary judgment or dismissal early in the case” 

but requiring a hearing to resolve fact disputes (quotations omitted)); Taboas v. 

Mlynczak, 149 F.3d 576, 581 (7th Cir. 1998) (stating substitution motion may be 

decided “akin to a summary judgment motion” on “affidavits and other evidence” 

“if the movant contests the facts as pled and the plaintiff is unable to demonstrate 

that a genuine issue of material fact exists with respect to the scope of employment”

(emphasis added)). Cf. Melo v. Hafer, 13 F.3d 736, 747 (3d Cir. 1994) (holding 28 

U.S.C. § 2679(d)(3)—which states a federal employee may “petition the court to 

find and certify that the employee was acting within the scope of his office or 

employment”—means that a court should “conduct an evidentiary hearing and make 
-5-

all findings necessary” to determine the scope of employment when material facts 

are disputed). 

Where there is an issue of material fact, conducting an evidentiary hearing is 

critical. If a plaintiff’s claims are intentional torts barred by the FTCA, as some are 

here, then substitution and the government’s FTCA defenses doom the plaintiff’s 

claims. See de Martinez, 515 U.S. at 427; 28 U.S.C. § 2680(h). 

Finally, “[i]f the court finds that the employee was acting outside of the scope 

of his employment, the court must refuse to substitute the United States.” Heuton, 

75 F.3d at 360. 

The law of the place in which the alleged tortious act occurred determines 

whether the defendant was acting within the scope of employment. Id.; Brown, 949 

F.2d at 1012 n.7. Iowa law governs here because all alleged acts occurred within 

its borders.

Under Iowa law, for an act to fall within the scope of employment, the act 

“must be of the same general nature as that authorized or incidental to the conduct 

authorized.” Godar v. Edwards, 588 N.W.2d 701, 705 (Iowa 1999), quoting

Sandman v. Hagan, 154 N.W.2d 113, 117 (Iowa 1967). An act falls outside the 

scope of employment only where it is a substantial deviation from the employer’s 

business or interest. Godar, 588 N.W.2d at 706; Sandman, 154 N.W.2d at 117. In 

addition, “conduct ‘in excess of the powers actually conferred on the servant’ may 

fall within the scope of . . . employment if the ‘act is necessary to accomplish the 

purpose of the employment and is intended for such purpose.’” Heuton, 75 F.3d at 

361, quoting Sandman, 154 N.W.2d at 117; Godar, 588 N.W.2d at 705. 

In assessing whether conduct falls within the scope of employment, Iowa 

courts have considered various aspects of the conduct, including: whether it was 

authorized, whether it was foreseeable, when and where it occurred, and the 

employee’s purpose in committing it. See Godar, 588 N.W.2d at 706-07 (finding 
-6-

acts outside scope of employment where “there was no evidence” that the 

employee’s “conduct was expected, foreseeable, or sanctioned” by his employer, 

and was not “in furtherance of his duties,” even though conduct occurred on 

employer’s property); Vlotho v. Hardin Cnty., 509 N.W.2d 350, 354-55 (Iowa 

1993) (assessing conduct’s authorization, time, purpose, foreseeability, and 

departure from past practice). The Iowa Supreme Court also has listed similar 

factors from Section 229(2) of the Restatement (Second) of Agency “to be 

considered in determining whether conduct of an employee [falls] within the scope 

of . . . employment,” although it has not mechanically tallied these factors. Godar, 

588 N.W.2d at 706. See also Vlotho, 509 N.W.2d at 354 (citing Restatement 

(Second) of Agency § 229). Ultimately, the scope-of-employment test is a “factintensive analysis.” Riggan v. Glass, 734 N.W.2d 486 at *3 (Iowa Ct. App. 2007)

(unpublished table opinion). See Restatement (Second) of Agency § 229 cmt. a 

(Am. L. Inst. 1958) (“The limits of the scope of employment are dependent upon 

the facts of the particular case . . . .”). See also Vlotho, 509 N.W.2d at 355 

(recognizing some facts supported conclusion that employee acted within his scope 

of employment, while others supported the opposite conclusion). 

Under the Iowa Supreme Court’s “same general nature” and “substantial 

deviation” rules, Rideout’s conduct fell within the scope of his employment. Most 

aspects of Rideout’s conduct suggest he acted within his scope of employment. Only 

one aspect—his purpose—arguably could favor the opposite finding but, even if it 

did, this alone would not outweigh the other relevant aspects of his conduct. 

First, the VHA, Rideout’s employer, largely authorized his conduct. Rideout 

first contacted supervisors and management within the Medical Center about his 

concerns on June 14, 2017. See 6/14/17 Email at 3, DCD 21-1. Plaintiffs do not 

dispute that these contacts were authorized. See Kearns Br. at 25 (challenging 

conduct after June 14, 2017).

Rideout’s subsequent contact with external entities largely remained within 

the VA’s normal, authorized, expected processes. The VHA whistleblower policy 
-7-

identifies a whistleblower as an employee “who reasonably believes that VHA has 

engaged in conduct that . . . violates professional or clinical standards; or that the 

care, services, or conditions provided by VHA potentially endangers one or more 

patients . . . .” VHA Privacy Fact Sheet at 15, DCD 22. The policy authorizes 

whistleblowers to disclose “sensitive personal information” to specific entities, 

including (1) “[a] public health authority authorized by law” to oversee VHA 

conditions, “such as state licensing boards,” (2) Congressional committees and 

subcommittees “authorized by law” to oversee the VHA, and (3) “[a]n appropriate 

health care accreditation organization . . . for the purpose of reporting the allegation 

of failure to meet professional standards or misconduct by VHA.” Id. The policy 

summary states that whistleblowers “may disclose to the media, a veterans’ service 

organization, or an attorney de-identified information,” which is information that 

would not be sufficient to identify a specific patient, id. at 14. It also elaborates in 

the frequently asked questions section: “A whistleblower may disclose health 

information de-identified in accordance with the HIPAA Privacy Rule and VHA 

Directive 1605.01 Appendix A without following the requirements discussed 

above,” apparently referencing the limitations on disclosure of sensitive personal 

information, id. at 16. See also VHA Directive 1605.01 App. A. at A-1 to A-2 

(Aug. 31, 2016) (providing standards for de-identified information); 45 C.F.R. § 

164.514(a) (2021) (defining de-identified information). Rideout contacted the 

relevant credentialing boards for Dettbarn and Kearns. See 7/31/17 Am. Registry 

of Radiological Techs. Letter at 2, DCD 21-6 (acknowledging receipt of Rideout’s 

letter alleging a violation of standards by Dettbarn); 8/27/19 Email at 2-11, DCD 

21-7 (stating, to Iowa Department of Health official, that information “is the same 

letter preparing [sic] for ARRT” and detailing allegations against Dettbarn); Rideout 

Dep. at 65:18-21, DCD 22 (confirming Rideout “filed a complaint with the Iowa 

Board of Nursing against” Kearns). These contacts fall squarely within those 

authorized by the whistleblower policy for sensitive personal information.

Rideout’s other external contacts form at most minor departures from the 

whistleblower policy. Rideout contacted the Iowa Department of Public Health 

(“IDPH”), which Plaintiffs assert lacked authority over the hospital. See 8/27/19 
-8-

Email at 2-11, DCD 21-7 (emailing IDPH official about Dettbarn); Kearns Br. at 

31. Rideout also contacted a staffer for Charles Grassley, U.S. Senator for Iowa, 

who did not serve in the oversight roles permitted by the VHA whistleblower policy, 

but did serve on the Senate Finance Committee’s Health Committee. See 7/21/17 

Email at 12-24, DCD 7-2 (contacting staffer about Kearns and Dettbarn). In both 

instances, the record reflects that Rideout disclosed only anonymized patient 

information not subject to the rigorous controls of the whistleblower policy. See id.

at 18, 23 (detailing situations in which Dettbarn allegedly endangered patient 

welfare by not following instructions, but not providing any information about the 

patient beyond the situation); 8/27/19 Email at 4-5, DCD 21-7 (same). As a result, 

Rideout was not prohibited from contacting the Iowa Department of Health or 

Senator Grassley’s staffer. Because the whistleblower policy authorized disclosing 

sensitive information to a “public health authority” or congressional committee with 

applicable oversight authority and also authorized broader dissemination of deidentified information, Rideout’s disclosure of anonymized information to Iowarelated entities responsible for healthcare oversight is not a significant departure, if 

any, from the normal method of protecting patient safety. 

Responses from VHA management reinforce the normalcy of Rideout’s 

conduct. As one high-ranking manager in the Radiology Department, Dr. Stanley 

L. Parker, summarized, “The VA has whistleblower protection, so anyone is allowed 

to file a complaint with any legal authority if they feel necessary.” Parker Dep. at 

17:6-16, DCD 22. See id. at 3:2-17 (identifying Parker’s roles); Dettbarn Suppl. 

Decl. ¶ 1, DCD 21-21 (same). Similarly, when one supervisor, Dr. David L. 

Bushnell, asked Rideout to address concerns only to himself or another supervisor, 

Rideout implied Bushnell was “discourag[ing] reporting” of the issues. 6/20/17 

Email at 2, DCD 21-2. In response, Bushnell acknowledged that Rideout “ha[d] 

the right” to report the problems he saw. Id. Another time, Rideout informed 

hospital management that he had notified the Iowa Department of Health. See

8/27/19 Email at 7, DCD 21-9 (forwarding 7/16/17 email to management). In 

response, they did not admonish him or suggest he had violated VHA policy. 

Instead, Bushnell responded by asking him to “document in real time” future issues 
-9-

that arose with radiological technologists and bring them to management, 7/17/17 

Email at 2, DCD 21-20, and another official directed him to bring concerns to a 

different official, 7/24/17 Email at 10, DCD 7-2 (suggesting Rideout speak with 

“Robin Hemphill”). These responses confirm that Rideout’s behavior did not depart 

much, if at all, from what the VHA authorized.

Second, the VHA had strong reason to foresee conduct like Rideout’s. The 

VHA authorized whistleblowing to protect patient safety. It had every reason to 

expect that employees would, in fact, blow the whistle on issues they viewed as 

endangering patients. Further, the fact that Rideout’s supervisors expressed no 

surprise when he informed them that he had alerted the Iowa Department of Health 

reinforces that his conduct did not depart from expectations. 

Third, the time and place of Rideout’s conduct also places it within the scope 

of his employment. Plaintiffs acknowledge that Rideout’s conduct, including “all 

material events,” “occurred at the VA Hospital,” and do not argue the place or time 

of his acts occurred outside his work hours.

Most aspects of Rideout’s conduct strongly support the conclusion that 

Rideout acted within his scope of employment. Rideout acted with authorization 

under VHA policy and approval from his superiors. The VHA’s policies made his 

conduct foreseeable. All relevant conduct occurred at the workplace, during 

business hours. These aspects suggest that Rideout’s conduct fell within and did not 

substantially deviate from his scope of employment. The evidence for these aspects 

consists of VHA policy and contemporaneous correspondence between Rideout, his 

supervisors, and oversight entities. The evidence does not depend on Rideout’s 

credibility.

The parties, however, contest the purpose of Rideout’s acts. Much of the 

record suggests Rideout’s intent was to serve the VHA, further placing his conduct 

within his scope of employment. Patient welfare is a clear purpose of the VHA. See

VHA Privacy Fact Sheet at 15, DCD 22 (authorizing whistleblowing about 
-10-

conduct that “potentially endangers” patients); 6/16/17 Bushnell Email at 3, DCD 

21-2 (recognizing concerns about misconduct affecting patients as “serious 

matters”). Rideout consistently stated that his concern was how Dettbarn’s and 

Kearns’s behavior affected patient wellbeing. See 6/14/17 Email at 3, DCD 21-2

(“My only concern is our patients and my ability to practice medicine.”); 7/15/27 

Email at 4, DCD 21-7 (discussing Dettbarn’s “disregard for patient health” when 

responding to an allergic reaction); 6/16/17 Email at 2, DCD 21-9 (stating concern 

that the environment was “creating an unsafe situation”).

Plaintiffs, on the other hand, argue that Rideout’s true purpose was to retaliate 

against them because VHA management took a policy position that supported them 

rather than Rideout—namely, that radiologists had to instruct technologists in 

writing if they wanted to deviate from approved protocols. Plaintiffs argue that 

Rideout’s rhetoric, the timing of his actions, and subsequent contradictions in his 

testimony underscore this true motive.

This argument fails because Rideout’s purpose, without more, does not render 

his acts a substantial deviation from his scope of employment. Purpose is but one 

of many aspects that Iowa courts consider in assessing scope of employment. See 

Godar, 588 N.W.2d at 706 (listing the “purpose of the act” as an aspect for 

consideration); Riggan, 734 N.W.2d 486 at *4 (concluding sufficient evidence 

supported finding that acts were within scope of employment where only one aspect 

supported a contrary finding). See also Brown, 949 F.2d at 1012 (finding 

“conclusory allegations of bad or personal motive” were insufficient to take conduct 

outside scope of employment where complaint otherwise pleaded conduct within it).

Indeed, Iowa precedent provides no rule that if an employee’s reason for 

committing an act is not the “purpose of employment,” Heuton, 75 F.3d at 361, then 

the act automatically falls outside the scope of employment. Rather, “conduct ‘in 

excess of the powers actually conferred on the servant’ may fall within the scope of 

the employee’s employment if the ‘act is necessary to accomplish the purpose of the 

employment and is intended for such purpose.’” Id., quoting Sandman, 154 N.W.2d 
-11-

at 117 (emphasis added). This means that an employee’s intent to accomplish the 

purpose of employment is one way to keep unauthorized conduct within that 

employee’s scope of employment (assuming the act also was required to accomplish 

that purpose). Intent represents a sufficient but not necessary cause of an act falling 

within the scope of employment.

2

 See Jones v. Blair, 387 N.W.2d 349, 355 (Iowa 

1986) (stating that “[a]n employee acts within the scope of his employment when 

the employer has the right to direct the means and manner of doing work, and has 

the right of control over the employee” (emphasis added)); Heuton, 75 F.3d at 361

(holding that conduct could fall within scope of employment under either Jones’s

right-of-control test or Sandman’s intent-and-necessity test).

Thus, intent by itself becomes dispositive only where no other sufficient cause 

is available to render an employee’s unauthorized conduct within the scope of 

employment. See id. (requiring—where demeaning photograph depicted employee 

plaintiffs as mother pig and suckling piglets, posting the photograph was 

“improper,” and “all the evidence in the record indicate[d] that posting [it] was 

unquestionably prohibited by” the employer—a “subjective inquiry into the . . . 

intent” of plaintiffs’ employee supervisor, assuming he had posted the photograph); 

Vlotho, 509 N.W.2d at 355 (concluding that, where employee “exceeded his 

authority” and demolished bridge “under stealth,” a “court could find that [his] 

actions were not intended to advance the interests” of his employer). See also 

Heuton, 75 F.3d at 361 (“Determining whether unauthorized conduct falls within 

2

As Heuton’s use of the permissive “may” suggests, the further wrinkle in this 

rule is that even if an employee commits an act necessary to accomplish the purpose 

of employment and has the intent to accomplish that purpose when committing the 

act, sometimes the act still will not fall within the scope of employment. Sometimes 

intent is not even sufficient. Thus, the rule effectively boils down to a description 

of one possible scenario of how the various factors weigh. This may be why the 

Iowa Supreme Court, in a post-Heuton ruling, framed the rule as synonymous with 

the general “substantial deviation” test. See Godar, 588 N.W.2d at 705-06 (stating 

intent rule, and immediately continuing, “The question, therefore, is whether the 

employee’s conduct ‘is so unlike that authorized that it is substantially different” 

(quoting Sandman, 154 N.W.2d at 117)).
-12-

the scope of employment, therefore, involves a subjective inquiry into the 

employee’s intent.” (emphasis added)); Godar, 588 N.W.2d at 706-07 (finding 

school district employee’s sexual molestation of student “cannot be reasonably said 

[to be] authorized by the school district” and then concluding his conduct was not 

“committed in furtherance of his duties”); Sandman, 154 N.W.2d at 118 (finding 

employee who attacked coworker with a shovel was not acting within scope of 

employment because, among other things, “[i]t is difficult to see how his [public 

works] employer’s business or interest would ever be furthered by such an employee 

attack”). Here, Rideout’s intent is not material, let alone dispositive, because the 

other aspects of his conduct squarely place it within his scope of employment.3

Even if purpose were dispositive, Plaintiffs would have to prove Rideout had 

no intent to benefit the VHA because conduct that serves “the purposes of the 

servant” may remain “within the scope of employment.” Restatement (Second) 

Agency § 236; see also id. cmt. a (stating that this rule includes when a servant 

“although performing his employer’s work, is [also] accomplishing his own 

objects”); Crowe v. De Soto Consol. Sch. Dist., 68 N.W.2d 63, 66 (Iowa 1955)

(finding, in worker’s compensation case, that teacher was within scope of 

3

If Rideout’s intent had been material or dispositive to his scope of 

employment, then an evidentiary hearing would have been required to the extent that 

Plaintiffs’ evidence—including circumstantial evidence—established an issue of 

material fact. See McAdams, 64 F.3d at 1145 (requiring an evidentiary hearing to 

resolve “material fact issues in dispute” for substitution of the government); Brown, 

949 F.2d at 1012; Heuton, 75 F.3d at 361 (vacating and remanding substitution 

decision where district court failed “to determine all the facts relevant” to scope of 

employment issue); Larsen v. Frederiksen, 277 F.3d 1040, 1041 (8th Cir. 2002)

(stating a plaintiff challenging the scope-of-employment certification “bears the 

burden of coming forward with specific facts rebutting the certification” (quoting 

Lawson, 103 F.3d at 60)); Hirani, 824 F.3d at 747 (“Circumstantial evidence is not 

only sufficient, but may also be more certain, satisfying and persuasive than direct 

evidence.” (quoting Desert Palace, Inc. v. Costa, 539 U.S. 90, 100 (2003))); Hirani, 

824 F.3d at 747 (concluding circumstantial evidence is “just as probative as direct 

evidence” to show willfulness in denaturalization proceeding). 
-13-

employment where she “was not on a mission solely for her own benefit,” despite a 

partly personal motive). 

Because Rideout’s intent is not material, and all other evidence shows Rideout 

acted within his scope of employment, an evidentiary hearing is not warranted.

The order granting substitution is affirmed.
