Tort Suits Against Federal Contractors: An Overview of the Legal Issues 
 
Summary 
Pending litigation and judicial decisions in recent tort suits filed by U.S. civilian and military 
personnel, other U.S. persons, and other parties against federal contractors have prompted 
congressional and public interest. Many of these suits allege that contractors were negligent or 
committed fraud or intentional torts (e.g., false imprisonment, infliction of emotional distress) in 
the course of providing services in support of combat operations in Iraq and Afghanistan.  
There has been particular interest in cases that have been dismissed on jurisdictional grounds, or 
because a federal court does not have power over the parties or subject matter. Personal 
jurisdiction over the defendant appears to be a particular issue in cases where the injury occurred 
while the contractor and U.S. persons worked for the government abroad. For example, courts 
recently disagreed as to whether they could exercise specific jurisdiction over contractors who 
allegedly exposed members of the National Guard to toxic chemicals at the Qarmat Ali water 
treatment plant in Iraq. Similarly, courts recently held that they cannot, absent additional contacts 
between the contractor and the forum state, exercise general jurisdiction over a contractor in any 
state from which the government administers the contract. 
The court’s subject matter jurisdiction can also be challenged or defeated. Some contractors have 
asserted that claims against them are nonjusticiable under the political question doctrine because 
resolution of these claims would require the court to decide issues that the Constitution has 
committed to another branch of government or that there are no judicially discoverable and 
manageable standards for resolving. To date, courts have reached differing conclusions as to 
whether the political question doctrine bars suits against federal contractors, although their 
decisions can, in part, be explained by differences in contract terms and performance.  
Other contractors have asserted that state tort law claims against them are preempted under the 
Federal Tort Claims Act. The Supreme Court’s decision in 
Boyle v. United Technologies 
Corporation recognized that such claims may be preempted where, among other things, the 
government approved reasonably precise specifications and the equipment manufactured by the 
contractor conformed to those specifications. While 
Boyle only addressed contracts for goods, 
recent decisions by some lower courts have extended it to service contracts, although there 
appears to be some disagreement between the courts as to how the test established in 
Boyle 
should be applied. Additionally, while the 
Boyle Court specifically based its decision on the 
“discretionary function” exception to the FTCA, some lower courts have found that state tort law 
claims may also be preempted under the FTCA’s “combatant activities exception.” Currently, 
there appear to be significant disagreements among the courts as to whether the combatant 
activities exception applies narrowly, only in circumstances like those in the cases originally 
recognizing it, or whether a broader “battlefield preemption” exists in certain cases.  
Contractors may also be able to claim derivative absolute immunity in certain circumstances if 
they are seen as performing discretionary functions, and the court finds that the contributions of 
immunity to “effective government” within the particular context outweigh the potential harm to 
individual citizens. However, contractors have been less successful in asserting derivative 
immunity under the 
Feres doctrine, which bars service members from bringing suit against the 
U.S. government for injuries that arise “out of or are in the course of activity incident to service.” 
In some cases, the government may have agreed to indemnify the contractor, or pay any liability 
that it might incur for injuries to third parties during performance of the contract.

Tort Suits Against Federal Contractors: An Overview of the Legal Issues 
 
Introduction 
Scores of contractors and contractor-employed personnel perform tasks, some of which are 
inherently dangerous, on the government’s behalf around the globe. Many work in areas of 
combat operations,1 in cooperation with or close proximity to civilian and military personnel.2 
Given this situation, the opportunity for events potentially giving rise to tort liability is arguably 
higher than it was in the past, when the government relied less heavily on contractors3 and 
contractors generally provided goods, not services, to the government.4  
Numerous suits have been filed in recent years by U.S. civilian and military personnel, other U.S. 
persons, and other parties alleging that federal contractors intentionally or accidentally injured 
them in the course of performing a government contract. These cases have generated significant 
congressional and public interest, in part because the cases can pit civilian or military personnel 
against large foreign or multinational corporations.5 These cases may also involve the 
performance of services that some commentators assert should not have been contracted out.6 In 
addition, the cases can tap into broader cultural beliefs about the purpose of the justice system 
(i.e., that wrongdoers should “pay,” literally or figuratively) and about “good government” (i.e., 
that the government should not “reward” “bad actors” by doing business with them).7  
                                                
1 The context within which the contractor operated could be relevant in determining its liability even if none of the 
jurisdictional challenges discussed below bar the suit. Several courts have suggested that standards of care may be 
lower in combat zones than in other places. 
See, e.g., McMahon v. Presidential Airways, Inc., 502 F.3d 1333, 1364 
(11th Cir. 2007) (“[Flying over Afghanistan during wartime is different from flying over Kansas on a sunny day,” but 
modified standards of negligence can be applied); Whitaker v. Kellogg Brown & Root, Inc., 444 F. Supp. 2d 1277, 
1282 (M.D. Ga. 2006) (“The question here is not just what a reasonable driver would do—it is what a reasonable driver 
in a combat zone, subject to military regulations and orders, would do.”).

8 Although it notes older cases where they are relevant, the report focuses primarily upon recent suits because changes 
in the government’s use of contractors could affect the court’s analysis of such cases. For example, the Department of 
Defense now explicitly recognizes contractor employees as part of its “total force,” and many commentators note that 
contractors play roles that are functionally akin to combat. 
See, e.g., Department of Defense, QUADRENNIAL DEFENSE

Other issues have also been raised, although far more rarely and with less success. 
See, e.g., Fisher v. Halliburton, 696 
F. Supp. 2d 710 (S.D. Tex. 2010) (rejecting defendants’ argument that the suit was barred by the Defense Production 
Act since they could have been criminally liable for failure to perform). There is also a possibility that the government 
could assert the state secrets privilege, thereby effectively preventing the case from proceeding. 
See, e.g., Mohamed v. 
Jeppesen Dataplan, Inc., 614 F.3d 1070 (9th Cir. 2010). For more on the state secrets privilege generally, see CRS

Tort Suits Against Federal Contractors: An Overview of the Legal Issues 
 
Tort Statute that are beyond the scope of this report,12 it also challenges the “battle-field 
preemption” doctrine which was recently articulated by the U.S. Court of Appeals for the District 
of Columbia Circuit in its decision in 
Saleh.13 If recognized by the Supreme Court, this doctrine 
could prove a significant jurisdictional bar in future tort suits against at least some government 
contractors. 
Basics of Tort Liability 
Generally, a tort is a private or civil wrong, other than breach of contract, for which a civil court 
will provide a remedy in the form of an action for damages. In other words, the tort system acts as 
a mechanism through which an individual who has suffered an injury or incurred damages caused 
by an act or omission of another (i.e., a tort-feasor) can seek compensation in court from that tort-
feasor. Tort law has its roots in the common or judge-made law.14 However, states have passed 
statutes that codify and sometimes change tort law. These changes can affect the availability and 
amount of remedies for a particular injury, for example. Therefore, when a plaintiff brings an 
action against a tort-feasor, the laws or court decisions of a state will govern the action. There are 
many civil wrongs included under the umbrella of torts, “ranging from simple, direct 
interferences with the person such as assault, battery and false imprisonment, or with property, as 
is the case of trespass or conversion, up through various forms of negligence.”15  
Although tort law “exists on a spectrum of culpability,”16 most plaintiffs seeking recovery bring 
their tort suits based on a theory of negligence, which has subsets of its own, such as negligent 
misrepresentation and the doctrine of “informed consent” in medical malpractice. Broadly 
speaking, in a tort action for negligence, a plaintiff needs to prove by the preponderance of the 
evidence that the defendant had a legal duty to the plaintiff, that the defendant breached this duty, 
and that such action or omission to act was the actual and/or proximate cause of the plaintiff’s 
injuries.  
A plaintiff must show negligent conduct, or the breach of duty, by establishing that the tort-feasor 
failed to use such care as a reasonably prudent and careful person would use under similar 
circumstances.17 This standard is generally considered ordinary negligence, in contrast to gross 
negligence, which is defined as “the intentional failure to perform a manifest duty in reckless 
disregard of the consequences as affecting the life or property of another.”18 The prevailing view 
is that there are no “degrees” of care in negligence, only different amounts of care as a matter of 
                                                
12 The Alien Tort Statute grants the federal courts jurisdiction over civil actions brought by aliens for torts “committed 
in violation of the law of nations or a treaty of the United States,” and could potentially grant foreign plaintiffs standing 
to bring suit against government contractors in federal court in certain circumstances. 28 U.S.C. § 1350. 
13 580 F.3d 1 (D.C. Cir. 2009). 
14 “New ... torts are being recognized constantly, and the progress of the common law is marked by many cases of first 
impression, in which the court has struck out boldly to create a new cause of action, where none had been recognized 
before. ... When it becomes clear that the plaintiff’s interests are entitled to legal protection against the conduct of the 
defendant, the mere fact that the claim is novel will not itself operate as a bar to the remedy.” W. Page Keeton, Prosser 
& Keeton on the Law of Torts, § 1 (5th ed. 1984) [hereinafter Prosser & Keeton, Torts].

fact; for purposes of this discussion, however, we point out that “ordinary” negligence is “based 
on the fact that one ought to have known the results of his act.”19 In contrast, gross negligence 
“rests on the assumption that one knew the results of his act, but was recklessly or wantonly 
indifferent to the results.”20 Furthermore, an action based on negligence is different than an action 
based on strict liability, in which the defendant is held liable without a finding of fault, so long as 
the plaintiff can establish that the tort occurred and that the defendant was responsible.  
Tort suits are not necessarily the only means of holding persons accountable for damages caused 
by their actions or inaction, or compensating persons for damages done to them.21 Depending 
upon the circumstances, other legal or non-legal recourse may be available, including criminal 
prosecution, suits based in contract, and workers’ compensation. However, tort suits are 
particularly appealing because injured parties can bring legal actions on their own behalf and 
recover monetary damages, unlike with criminal prosecutions. Also, tort suits may be brought in 
circumstances where criminal prosecutions are not possible, either because the standard of proof 
is higher in criminal cases than in tort suits22 or for other reasons.23 Similarly, persons generally 
need to be in “privity of contract,” or be a party to the contract, in order to have standing to 
recover on a suit in contract.24 Persons who are not parties to the contract can sometimes be 
classified as “third party beneficiaries” to it, but third party beneficiary status is an “exceptional 
privilege,”25 which courts generally will not grant unless the plaintiff can demonstrate that the 
contract “not only reflects the express or implied intention to benefit the party, but that it reflects 
an intention to benefit the party directly.”26 In addition, the amount of damages potentially 
recoverable in contract is generally smaller than that which can be recovered in tort.27

20 Black’s Law Dictionary 717 (6th ed. 1991).  
21 Tort law can be seen as having various purposes, which are not always compatible, including “provid[ing] a remedy 
for the innocent victim of wrongful conduct” and ensuring that “tortfeasors … suffer for their sins.” Koohi v. Varian

23 For example, contractors working in Iraq could not be prosecuted under Iraqi law prior to January 1, 2009, and they 
generally cannot be prosecuted under U.S. law unless they are covered by the Military Extraterritorial Jurisdiction Act 
of 2000 (MEJA), the Uniform Code of Military Justice (UCMJ), or similar statutes.

Tort Suits Against Federal Contractors: An Overview of the Legal Issues 
 
In some circumstances, however, injured persons may be barred from filing tort suits. For 
example, employees (but not independent contractors) are generally barred by the Defense Base 
Act (DBA) and other workers’ compensation laws from suing their employers in tort for injuries 
incurred “in the course of” or “because of” their employment.28 Members of the military are 
similarly barred, under the 
Feres doctrine, from bringing suit against the U.S. government for 
“injuries [that] arise out of or are in the course of activity incident to service.”29 The 
Feres 
doctrine currently does not bar suits against government contractors working for the military,30 
although some contractors have argued that it should be extended to preclude such suits,31 and 
some commentators have asserted that the 
Feres doctrine leads service members to seek damages 
from contractors that they could not recover from the government.32 
Personal Jurisdiction 
The requirement that the court have personal jurisdiction over the defendant flows from the Due 
Process Clause of the U.S. Constitution and represents a restriction on judicial power as a matter 
of individual liberty.33 The analysis of whether a federal court would have personal jurisdiction 
over a defendant can be a complicated matter that is generally outside the scope of this report. 
However, personal jurisdiction issues have arisen in several contractor tort suits of particular 
interest to some Members of Congress and so are briefly noted here.  
For a federal court to exercise personal jurisdiction, its doing so must be both authorized by 
statute and consistent with constitutional requirements.34 However, because courts’ authority to 
assert personal jurisdiction under the federal “long arm” statute is generally coextensive with the

would be “reasonable in relying on the promise as manifesting an intention to confer a right on him.” 
Montana, 124 
F.3d at 1273.  
27 In particular, punitive damages may be recovered in tort, while they generally may not be recovered in contract. 
See, 
e.g., Metroplex Corp. v. Thompson Indus., 25 Fed. App’x 802 (10th Cir. 2002). The statute of limitations for filing a 
contract action is, however, generally longer than that for filing an action in tort.  
28 
See, e.g., Nauert v. Ace Prop. & Cas. Ins. Co, Civil Action No. 04-CV-02547-WYD-BNB, 2005 U.S. Dist. LEXIS 
34497 (D. Colo. Aug. 27, 2005) (finding that the DBA and the Longshore and Harbor Workers’ Compensation Act 
preempted an employee’s state-law claim alleging that an insurance company acted in bad faith when it denied his 
claim seeking payment of medical bills and disability compensation for an injury he sustained while working at an 
American military base in Kosovo). 
But see Nordan v. Blackwater Security Consulting, LLC, 382 F. Supp. 2d 801 
(E.D. N.C. 2005), 
aff’d 460 F.3d 576, 582 (4th Cir. 2006) (holding that the DBA does not represent the contractor’s 
exclusive liability and does not preempt state tort law claims); Fisher v. Halliburton, Inc., 390 F. Supp. 2d 610, 613 
(S.D. Tex. 2005) (holding that intentional torts are not covered by the DBA).

30 
See, e.g., 
Chapman, 911 F.2d at 271; Durant v. Neneman, 884 F.2d 1350, 1351 (10th Cir. 1989).

Insurance Corp., 456 U.S. at 701. Personal jurisdiction consists of two distinct components, amenability to 
jurisdiction and service of process. Amenability to jurisdiction means that the defendant is within the substantive reach 
of the forum’s jurisdiction under applicable law. Service of process is simply the physical means by which jurisdiction 
is asserted. While both components may be at issue in some cases, in most cases, discussions of personal jurisdiction 
focus upon amenability to jurisdiction, as does the discussion here.

jurisdiction of the courts of the state in which they sit,35 and many states permit their courts to 
exercise jurisdiction to the extent permitted by the constitution,36 analysis of personal jurisdiction 
questions generally turns upon the Due Process requirements. Under the Due Process Clause, the 
exercise of personal jurisdiction is constitutional if the defendants have “minimum contacts” with 
the state, such that the assertion of jurisdiction “does not offend traditional notions of fair play 
and substantial justice.”37 The amount of contact necessary to meet the constitutional minimum 
requirements depends, in part, upon which type of personal jurisdiction—general or specific—is 
asserted. General jurisdiction, which allows a court to exercise jurisdiction over a defendant for 
any claim, requires “continuous and systematic general business contacts … that approximate 
physical presence in the forum state.”38 These contacts do not have to be related to the cause of 
action. In contrast, specific jurisdiction requires that a defendant’s contacts with the forum “relate 
to” or “arise out of” the claims at issue in the case.39 There is no “continuous and systematic” 
requirement, but jurisdiction is limited to the claims in the particular case. Because personal 
jurisdiction represents an individual’s constitutional right, it can be waived by, among other 
things, contracting in advance to submit to the jurisdiction of a particular court.40 
The differing outcomes in the five cases, to date, arising from contractors’ alleged negligence and 
fraud in exposing current and former members of the National Guard to sodium dichromate at the 
Qarmat Ali water treatment facility in Iraq illustrate the difficulties that plaintiffs can face in 
establishing personal jurisdiction. In one of these cases, 
Bixby v. KBR, Inc., the court found that 
the defendants’ contacts with the State of Oregon were insufficient for general jurisdiction, given 
these contacts consisted of: (1) registrations to do business in Oregon; (2) designated agents for 
service of process; (3) an omnibus workers’ compensation policy covering 42 states, including 
Oregon; and (4) the employment of approximately 40 people who listed Oregon as their state of 
permanent residence, although none are employed in Oregon.41 However, the court found that it 
had specific jurisdiction over plaintiffs’ claims under the “effects test” articulated by the Supreme 
Court in 
Calder v. Jones.42 Under this test, a court may exercise jurisdiction over a defendant who 
allegedly committed an intentional tort, expressly aimed at the forum state, that the defendant 
knows is likely to cause harm within the forum state. The 
Bixby court found that this test was 
satisfied, in part, because the defendant intentionally misrepresented and concealed conditions at 
Qarmat Ali from the plaintiffs, knowing they were members of the Oregon National Guard.43 The 
court further found that “any long-term harm suffered by the plaintiffs” would necessarily be felt 
in Oregon, which the defendants knew was likely to be the case given that they knowingly failed 
to disclose conditions to persons known to be from Oregon.44 In contrast, in another of these 
cases, 
McManaway v. KBR, Inc., the court found that it lacked both general and specific

jurisdiction.45 In particular, it found that the “effects test” was not satisfied because, assuming 
plaintiffs’ claims were true, the defendants directed their allegedly tortious conduct to all 
individuals visiting Qarmat Ali, not just those from Indiana.46 The court also distinguished 
between the cause and effects of the alleged harm, finding that the cause occurred in Iraq, even if 
the effects were only felt after the plaintiffs returned to Indiana.47 The court in 
Gallaher v. KBR, 
Inc., reached the same conclusion when applying the “effects test,”48 as did that in 
Billiter v. KBR, 
Inc.49 In yet another of these cases, 
Bootay v. KBR, Inc., the plaintiffs did not assert specific 
jurisdiction, and the court found that it lacked general jurisdiction over the three defendants who 
contested it because they lacked sufficient contacts with the forum.50 However, while the 
outcomes in four of these five cases were undoubtedly frustrating for the plaintiffs, the plaintiffs 
could potentially seek a remedy in other jurisdictions where the defendants’ contacts are more 
substantial because the defendants are domestic corporations.51 
Difficulties in asserting personal jurisdiction may be more intractable when the defendant is a 
foreign person who allegedly injured U.S. persons through actions or inaction abroad. That was 
situation in 
Baragona v. Kuwait Gulf Link Transport Company.52 There, in an apparent case of 
first impression, the plaintiffs asserted that the Kuwaiti defendant should be subject to the general 
jurisdiction of the federal courts in Georgia because the headquarters of the procuring activity 
were located in Georgia and the contract was administered from there.53 Although the court 
ultimately found that the procuring activity was not, in fact, located in Georgia at the time of 
contracting and did not administer the defendant’s contracts from there,54 its holding was broader, 
stating that the “due process clause does not permit exercising jurisdiction over a United States … 
contractor in the state where the [government] chooses to administer the contract, independent of 
any other contacts between the contractor and the state.”55 The court’s holding is arguably 
unsurprising given that the Supreme Court has emphasized that defendant’s contacts with the 
forum state must be the result of the defendant’s intentional actions, not due to the unilateral 
activity of a third party.56 The 
Baragona court also held, in another apparent question of first 
impression, that the contractor did not waive its personal jurisdiction defense by entering into a 
contract that contains language like that found in Section 52.228-8 of the Federal Acquisition 
Regulation (FAR), which obligates contractors to obtain additional insurance against the claims 
of third parties.57

Tort Suits Against Federal Contractors: An Overview of the Legal Issues 
 
Subject Matter Jurisdiction 
While the requirement that courts have personal jurisdiction flows from the Due Process Clause 
of the Constitution, the requirement that courts have subject matter jurisdiction derives from 
Article III, which represents a “restriction on judicial power … as a matter of sovereignty.”58 
Among other things, Article III requires the existence of a “case or controversy” for a court to 
have jurisdiction.59 Courts may find that this requirement is not satisfied when a “political 
question,” or a question which the Constitution has committed to another branch of government,60 
is “inextricably” involved in the resolution of the case.61 Alternatively, the court may find that it 
cannot exercise jurisdiction over the plaintiff’s claims because federal law preempts the state tort 
law claims which the plaintiff is asserting, or because the contractor has immunity from suit.62  
Political Question Doctrine 
While commentators have noted numerous complexities pertaining to the political question 
doctrine, including whether it represents a formal or functional limitation upon courts’ 
jurisdiction,63 the notion that courts should refrain from deciding questions that the Constitution 
has entrusted to other branches of government has a lengthy history in American jurisprudence. In 
his 1803 decision in 
Marbury v. Madison, Chief Justice Marshall distinguished between 
“decid[ing] on the rights of individuals,” which he viewed as within the Court’s power, and 
“inquir[ing] how the executive, or executive officers, perform duties in which they have a 
discretion,” which he viewed as beyond the Court’s power.64 Marshall concluded that “[q]uestions 
in their nature political, or which are, by the constitution and laws, submitted to the executive can 
never be made in this court.”65 More recently, in its 1962 decision in 
Baker v. Carr, the Supreme 
Court articulated the prevailing standards for determining whether a political question is 
inextricably implicated in the resolution of a case. There, in reversing a lower court’s holding that 
a challenge by voters to a state’s system for establishing political districts was nonjusticiable on 
political question grounds, the Court noted that:  
Prominent on the surface of any case held to involve a political question is found [1] a 
textually demonstrable constitutional commitment of the issue to a coordinate political 
department; or [2] a lack of judicially discoverable and manageable standards for resolving 
it; or [3] the impossibility of deciding without an initial policy determination of a kind 
clearly for nonjudicial discretion; or [4] the impossibility of a court’s undertaking 
independent resolution without expressing lack of the respect due coordinate branches of

government; or [5] an unusual need for unquestioning adherence to a political decision 
already made; or [6] the potentiality of embarrassment from multifarious pronouncements by 
various departments on one question.66 
Based upon one or more of the factors articulated in 
Baker, courts subsequently found cases 
nonjusticiable on political question grounds when determining the defendant’s liability, or 
otherwise resolving the case, would require them to determine the adequacy of the training 
procedures used by the National Guard, resolve territorial disputes between sovereigns, establish 
standards for intercepting aircraft entering U.S. airspace, or determine the necessity of simulating 
battle conditions, among other things.67 As these cases illustrate, political questions arise with 
some frequency in cases involving military and foreign affairs. However, not every case that 
involves military or foreign affairs necessarily presents a political question.68 
Although the political question doctrine was apparently first asserted in tort suits against federal 
contractors in which the government intervened,69 contractors have most recently asserted it in 
cases where the government has not intervened.70 The outcomes in these cases have varied 
widely,71 prompting some commentators to suggest that “uniform treatment and predictable 
standards” are lacking.72 To illustrate the ostensible confusion among the cases, commentators 
sometimes point to the differing opinions issued by the U.S. Courts of Appeals for the Fifth and 
Eleventh Circuits, respectively, in 
Lane v. Halliburton and 
Carmichael v. Kellogg, Brown & Root

Services, Inc.73 Both cases arose from accidents that occurred on contractor-operated fuel convoys 
in Iraq during the Gulf War. However, in 
Lane, the Fifth Circuit reversed a district court decision 
dismissing the case on political question grounds, in part, because “we cannot find that all 
plausible sets of facts that could be proven would implicate particular authority committed by the 
Constitution to Congress or the Executive.”74 The 
Lane court also noted that, while at least some 
of the plaintiffs’ allegations could draw the court into consideration of what constituted adequate 
force protection for the convoys, some could potentially be proven without considering the 
“Army’s role” in events.75 In contrast, in 
Carmichael, the Eleventh Circuit affirmed a district 
court decision dismissing the case on political question grounds.76 The 
Carmichael court reached 
this conclusion, in part, because determining whether the convoy driver was responsible for the 
injuries of a soldier riding along in his vehicle “would require reexamination of many sensitive 
judgments and decisions entrusted to the military in a time of war,”77 given that “military 
judgments governed the planning and execution of virtually every aspect of the convoy,” 
including the date and time of its departure, the speed and route of travel, the distance between 
vehicles, and the security measures taken.78 The court also found that there were no judicially 
discoverable and manageable standards for resolving whether the driver was negligent because 
“the convoy was subject to military regulation and control,” and the standards used in “ordinary 
tort cases” would not apply.79 
Despite the factual similarities between the cases, the differing outcomes in 
Carmichael and 
Lane can arguably be reconciled given the courts’ differing conclusions about the degree of control that 
the contractor retained over its operations under applicable regulations, the terms of the contract, 
and the course of performance under the contract. In 
Lane, where the court viewed KBR’s 
“policies and actions” as potentially separable from those of the military, the court found 
dismissal on political question grounds to be improper, at least prior to the completion of 
discovery.80 In 
Carmichael, on the other hand, the court viewed the contractor’s policies and 
actions as inseparable from those of the military because, among other things, regulations granted 
the military “plenary control” over the convoy; the contract demanded the drivers be trained to 
military standards; and all parties to the contract viewed the military as having “complete control” 
of the convoy.81 In fact, the court expressly rejected the plaintiffs’ attempt to distinguish between

they were challenging “the wisdom of the military’s use of civilian contractors in a war zone.”

the military’s control of the convoy and the driver’s control of the vehicle because “[t]he fact that 
[the driver] had physical control over his tanker does not change the fact that he was operating at 
all times under orders and determinations made by the military.”82 
Other factors also help account for the differing outcomes in 
Lane, 
Carmichael, and similar cases. 
Whether the plaintiff alleges negligence or an intentional tort (e.g., false imprisonment, 
intentional infliction of emotional distress) is one such factor. Courts appear more likely to find 
that cases are barred on political question grounds when the plaintiff alleges negligence than 
when the plaintiff alleges an intentional tort,83 perhaps because commission of an intentional tort 
is more clearly within the contractor’s “control.” The tort law of the jurisdiction can also play a 
role, with the political question doctrine apparently more likely to bar suits in jurisdictions which 
recognize contributory negligence.84 Contributory negligence is a tort doctrine which precludes 
plaintiffs whose own negligence is a proximate cause of their injuries from recovery, and the 
possibility of contributory negligence could be significant if the plaintiffs are military or civilian 
government personnel whose actions or inaction potentially resulted from executive branch 
policies.85 Yet another factor is the nature of the remedy sought. Courts have long recognized that 
political questions are more likely to arise in negligence cases when plaintiffs seek to enjoin 
particular conduct than when plaintiffs seek monetary damages.86 Finally, the timing of the 
defendant’s motion to dismiss on political question grounds can also be significant. While many 
early district court cases based on injuries incurred during military operations in Afghanistan and 
Iraq were dismissed prior to the completion of discovery,87 more recent appeals court decisions 
suggest that dismissal is generally only appropriate after the completion of discovery,88 when it 
can be said with more certainty that plaintiff could not prove any plausible set of facts allowing 
the plaintiff to recover without compelling the defendant to answer a political question.89 
While 
Carmichael and similar cases suggest that federal contractors may be able to successfully 
assert the political question doctrine in at least some tort suits, several potentially significant 
questions remain unanswered. It is unclear how other jurisdictions and, particularly, the Supreme 
Court would view the factors that were seen as determinative by the courts that have decided 
these cases to date. Many tort suits against federal contractors have been heard in the Fifth and 
Eleventh Circuit because that is where the contractors who were most heavily involved in

Tort Suits Against Federal Contractors: An Overview of the Legal Issues 
 
operations in Iraq, in particular, are located.90 It is thus less certain how courts in other circuits 
would approach these cases. Additionally, some commentators have suggested that the Supreme 
Court is not favorably inclined toward the political question doctrine at present.91 Relatedly, there 
appears to be disagreement among the federal courts of appeals as to what significance, if any, 
attaches to the government’s failure to intervene in a suit against a contractor. Some circuits 
seemingly view the government’s failure to intervene as insignificant,92 while others view it as 
weighing against dismissal of the case on political question grounds.93 
Preemption Under the Federal Tort Claims Act 
Even if plaintiffs’ claims against a government contractor are not barred by the operation of the 
political question doctrine, the court could still find that it cannot exercise jurisdiction over these 
claims because the claims are preempted under the Federal Tort Claims Act (FTCA). As a 
sovereign, the federal government is immune from suit without its consent.94 The FTCA waives 
the government’s sovereign immunity,95 but this waiver is subject to many exceptions. Although 
the FTCA is not directly applicable to contractors, courts have crafted several “federal common 
law” defenses that shield government contractors from liability under the FTCA’s exceptions. The 
most prominent of these are the government contractor defense and the combatant activities 
exception. However, some contractors have also asserted “derivative sovereign immunity” 
generally under the FTCA. 
Government Contractor Defense 
The government contractor defense is a judicially created doctrine that bars courts from hearing 
certain cases because the state tort law claims raised in the case are preempted. The defense 
derives from the Supreme Court’s decision in 
Boyle v. United Technologies Corporation, which 
both articulated the reasons for recognizing a government contractor defense and created a test to

inform courts if the executive branch believes the act of state doctrine applies to pending litigation.

determine when state law should be “displaced” or preempted.96 According to the Court, the 
“uniquely federal interest” in “civil liabilities arising out of the performance of federal 
procurement contracts” is such as to warrant preemption of state law and its replacement with 
“federal law of a content prescribed (absent explicit statutory directive) by the courts—so-called 
‘federal common law.’”97 In place of the preempted state tort laws, under which the petitioners 
had sued a contractor who manufactured a helicopter that allegedly malfunctioned, causing the 
death of a Marine pilot, the Court substituted a two-prong test to determine when state law should 
be displaced and a three-part test to determine the scope of displacement. 
Boyle’s two-prong test 
asks whether (1) the claim involves an area of “uniquely federal interest” and (2) there is “a 
‘significant conflict’ … between an identifiable ‘federal policy or interest and the [operation] of 
state law’ … or the application of state law would ‘frustrate specific objectives of federal 
legislation.’”98 Assuming this test is satisfied, 
Boyle’s three-part test, resulting in claims being 
preempted where:  
1.  the United States approved reasonably precise specifications;  
2.  the equipment conformed to those specifications; and  
3.  the supplier warned the United States about the dangers in the use of the 
equipment that were known to the supplier but not to the United States.99 
While 
Boyle is often cited for this three-part test, several other aspects of the decision should be 
noted because of their relevance to ongoing litigation. First, the Court explicitly recognized that 
procurement of equipment by the United States is an area of “uniquely federal interest.” Second, 
the Court expressly held that the state-prescribed duty of care may be preempted when a 
contractor cannot comply with both this duty and its contractual obligations to the federal 
government.100 Third, and perhaps most importantly, the Court grounded, or rooted, the 
government contractor defense in the “discretionary function” exception to the Federal Tort 
Claims Act.101 This exception bars any claim against the United States that is “based upon the 
                                                
96 487 U.S. 500 (1988). 
97 
Id. at 504-05. In so concluding, the Court rejected the petitioners’ broad contention that, absent legislation 
specifically immunizing government contractors from liability for design defects, there is no basis for judicial 
recognition of a military contractor defense. It noted that there have, in fact, been a few areas involving “uniquely 
federal interests” where it has found state law preempted and replaced, where appropriate, with “federal common law.” 
Id. at 504. Noting that it has found the civil liability of federal officials for actions taken in the course of their duty to be 
an area of “peculiarly federal concern,” the Court also cited 
Yearsley v. W.A. Ross Construction Co., as support for the 
principle that it has found “civil liabilities arising out of the performance of federal procurement contracts” to be an 
area of “uniquely federal interest.” 
Id. at 505-06. In 
Yearsley, the Court held that there was no liability on the part of a 
government contractor for executing the will of the government if the authority for its actions was “validly conferred.” 
See 309 U.S. 18 (1940).  
98 
Boyle, 487 U.S. at 507.  
99 
Id. at 512. According to the Court, the first two conditions ensure “the suit is within the area where the policy of the 
‘discretionary function’ would be frustrated—i.e., ... the design feature in question was considered by a Government 
officer, and not merely by the contractor itself.” 
Id. The third condition, in contrast, provides an incentive for 
manufacturers to provide information about risks to the government.  
100 
Id. at at 509. According to the Court, “[d]isplacement [of state law] will occur only where ... a ‘significant conflict’ 
exists between an identifiable ‘federal policy or interest and the [operation] of state law’ … or the application of state 
law would ‘frustrate specific objectives of federal legislation.’” 
Id. at 507. However, the Court further stated: “The 
conflict with federal policy need not be as sharp as that which must exist for ordinary pre-emption when Congress 
legislates in a field which the States have traditionally occupied ... But conflict there must be.” 
Id. at 509. In other 
words, state law would not be displaced “where a duty sought to be imposed on the contractor is not identical to one 
under the contract, but also not contrary to any assumed [under the contract].”

Tort Suits Against Federal Contractors: An Overview of the Legal Issues 
 
exercise or performance or the failure to exercise or perform a discretionary function or duty on 
the part of a federal agency or an employee of the Government, whether or not the discretion 
involved be abused.”102 In particular, the 
Boyle Court found a discretionary function is implicated 
whenever the government chooses the appropriate designs for military equipment.103 
Because 
Boyle involved a contract for the procurement of goods, some plaintiffs have asserted 
that the government contractor defense does not apply to contracts for services. The exclusion of 
service contracts from the government contractor defense could have significant implications for 
recent tort suits against government contractors, given that most government contracts are now 
for services, not goods.104 While two recent decisions from the U.S. Courts of Appeals for the 
Fifth and Eleventh Circuits suggest that service contractors may be able to successfully assert the 
government contractor defense in certain circumstances, there appear to be some questions about 
its application.  
In the earlier of these two decisions, 
Hudgens v. Bell Helicopters/Textron, the Eleventh Circuit 
expressly rejected the defendant’s argument that the government contractor defense should not be 
extended to service contracts because “immunity from tort liability is the exception to the general 
rule.”105 According to the court: 
Although 
Boyle referred specifically to procurement contracts, the analysis it requires is not 
designed to promote all-or nothing rules regarding different classes of contract. Rather, the 
question is whether subjecting a contractor to liability under state tort law would create a 
significant conflict with a unique federal interest.106 
Then, having found that the government contractor defense extended to service contracts, the 
court applied the three-part test from 
Boyle to find that the plaintiffs’ claims against the contractor 
were preempted because the Army approved reasonably precise maintenance procedures; the 
defendant’s performance of maintenance conformed to those procedures; and the defendants had 
informed the Army of the dangers associated with not adopting certain precautions recommended 
by the Federal Aviation Administration and Bell Helicopters.107  
                                                             
(...continued) 
identify those situations in which a significant conflict arises between federal interests and state law. It found that 
application of the 
Feres doctrine as a limiting principle would produce results that were both too broad and too narrow. 
Because the 
Feres doctrine “prohibits all service-related tort claims against the Government, a contractor defense that 
rests upon it should [likewise] prohibit all service-related tort claims against the manufacturer.” 
Id. at 510. On the other 
hand, because the doctrine only covers service-related injuries, and not injuries caused by the military to civilians, “it 
could not be invoked to prevent, for example, a civilian’s suit against the manufacturer.” 
Id. at 510-511.

See supra note 4 and accompanying text. Moreover, many of today’s contracts for goods are for “commercial 
items,” which, by definition, are not goods made to the government’s specifications.

“commercial item”).

protocols to involve the exercise of the same discretion that would be required to choose design specifications.

Tort Suits Against Federal Contractors: An Overview of the Legal Issues 
 
The Fifth Circuit also applied the government contractor defense to a service contract in 
In re: 
Katrina Canal Breaches v. Washington Group International.108 However, the Fifth Circuit 
construed 
Boyle as requiring only the application of the three-part test pertaining to the 
specifications, not the application of the two-prong and three-part test. According to the Fifth 
Circuit, the first step of the three-part test (i.e., asking “whether the Government approved 
reasonably precise specifications for the design feature in question”) “necessarily answers the 
question whether the federal contract conflicts with state law.”109 Further, in determining whether 
there was such a conflict, the court looked not to the specifications for the entire project, but 
rather the specifications for the specific feature at issue in the claim. It found that because the 
specifications were not reasonably precise in this case, the defendant contractors were not entitled 
to the government contractor defense, and the state law applicable to the defendants was not 
preempted.110 
Both 
Hudgens and 
In re: Katrina Canal Breaches demonstrate a direct application of the 
government contractor defense as iterated in 
Boyle to the claims at issue. Although the courts 
apparently differed as to the necessity of applying the two-prong preemption test,111 each court 
extended the application of the three-part test to cover actions pursuant to contracts for services. 
In addition, both cases acknowledged that the discretionary function was the limiting principle 
chosen by the Supreme Court to determine if a significant policy or federal interest is threatened 
by the operation of state law. However, as more tort suits against contractors have been brought, it 
seems as if the government contractor defense laid out in 
Boyle has been expanded by the courts, 
specifically with respect to the combatant activities exception, as is discussed below. Whether this 
was the intention of the Supreme Court in 
Boyle has also been the subject of commentary by 
some courts.112 
Combatant Activities Exception to the FTCA 
As noted above, the Supreme Court in 
Boyle grounded the government contractor defense in the 
discretionary function exception to the FTCA. Since then, defendant-contractors have also 
asserted that claims against them are preempted under the combatant activities exception to the 
FTCA. This exception precludes tort liability in “[a]ny claim arising out of the combatant 
activities of the military forces, or the Coast Guard, during a time of war.”113 The courts that have

109 
Id.
 at 460 (
citing Lewis v. Babcock Indus. Inc., 985 F.2d 83, 86 (2d Cir. 1993)). The court dismissed plaintiffs’ 
argument that the first inquiry should be whether a significant conflict exists between federal policy and state law, 
stating that this threshold inquiry, as articulated by 
Boyle, “has never been required by any court, nor should it be.” 
Id. 
at 461.  
110 
Id. at 465.  
111 Although the Eleventh Circuit apparently did not apply the two-prong test within the context of the specific facts 
and circumstances of the case, its discussion of 
Boyle included the two-prong test, and its decision can be read as 
construing 
Boyle to mean that procurement contracts entail uniquely federal interests, and there are significant conflicts 
when contract specifications cannot be fulfilled consistently with duties imposed by state law. In any case, the court did 
not state that only the three-part test of 
Boyle should be applied, unlike the Fifth Circuit.

Tort Suits Against Federal Contractors: An Overview of the Legal Issues 
 
recognized contractors’ assertion of this defense have generally done so by, knowingly or 
unknowingly, linking it to the government contractor defense recognized in 
Boyle. 
Two early cases—
Koohi v. Varian Associates, Inc.114 and 
Bentzlin v. Hughes Aircraft Co.115—first 
extended the application of the combatant activities exception to government contractors in 
certain limited circumstances. Both cases involved product liability claims. In 
Koohi,
 the U.S. 
Court of Appeals for the Ninth Circuit extended the combatant activities exception to preempt 
claims against a weapons manufacturer on the grounds that:  
[O]ne purpose of the combatant activities exception is to recognize that during wartime 
encounters[,] no duty of reasonable care is owed to those against whom force is directed as a 
result of authorized military action. ... The imposition of such liability on the manufacturers 
of the Aegis would create a duty of care where the combatant activities exception is intended 
to ensure that none exists.116 
However, the Ninth Circuit’s arguably brief discussion left it unclear whether the court 
intended to utilize the government contractor defense to explain the extension of the 
combatant activities exception to contractor. However, subsequent courts have done so, 
or concluded that this was the Ninth Circuit’s intent.117  
Bentzlin is like 
Koohi in that the U.S. District Court for the Central District of California 
seemed to base the combatant activities exception, in part, on the government contractor 
defense.118 The 
Bentzlin court explicitly addressed whether the government contractor 
defense could be extended to suits arising from wartime activity (i.e., combatant 
activities) and found that it could because (1) there is a unique federal interest in the 
procurement of highly sophisticated weapons; and (2) there would be a significant 
conflict between federal policy (rooted in the discretionary function exception) and the 
operation of state tort law. 119 
Bentzlin also expanded upon 
Koohi’s use of the combatant 
activities exception by noting that while 
Koohi limited its application of the combatant 
activities exception to suits involving “enemies” of the United States, nothing in 
Koohi suggested that it was intended to be so narrowly construed. The court reasoned that “[i]n 
a wartime context, state law cannot establish a duty of care owed to American soldiers 
who necessarily assume the risk of death.”120

115 
Bentzlin, 833 F. Supp. 1486. 
116 
Koohi, 976 F.2d at 1337. 
117 The court did not explore the 
Boyle two-prong test to discuss if the government contractor defense would be 
applicable by examining if a unique federal interest is at stake and if the federal interest would be threatened by 
operation of state law. It also did not explicitly discuss utilizing the combatant activity exception as the limiting 
principle as the Supreme Court had done with the discretionary function exception in 
Boyle. 
118 833 F. Supp. at 1489. 
119 
Id. at 1492. The 
Bentzlin court specifically held that the government contractor defense supports preemption of 
manufacturing defect suits arising in the context of war because the application of tort law principles—deterrence, 
punishment, and providing a remedy to innocent victims—to suits arising from combat “would frustrate government 
combat interests.”

See also McMahon, 460 F. Supp. 2d at 1330 (opining that

activity (‘combatant preemption’).”). 
Congressional Research Service 
16 
Tort Suits Against Federal Contractors: An Overview of the Legal Issues 
 
More recent decisions on the combatant activities exception have diverged as to its scope,121 with 
some parties and courts viewing the combatant activities exception primarily through the 
framework of 
Koohi and 
Bentzlin and others considering the exception more broadly in light of 
the government contractor defense recognized in 
Boyle. The courts in 
Flanigan v. Westwind 
Technologies and 
Lessin v. Kellogg Brown & Root, Inc., for example, approached the combatant 
activities exception primarily through the framework of 
Koohi and 
Bentzlin. They concluded, 
respectively, that the plaintiffs’ claims fell within those preempted under 
Koohi/Bentzlin because 
they involved the procurement of “complex equipment” by the government,122 or were 
distinguishable from those in 
Koohi/Bentzlin because they did not arise from the “United States’ 
use of weapons during combat,” and contractors have a duty of care to U.S. persons (as opposed 
to perceived enemies) during combat.123  
In contrast, in 
Saleh v. Titan Corporation, the U.S. Court of Appeals for the District of Columbia 
Circuit looked to 
Boyle in expanding the reach of the combatant activities exception. 
Saleh arose 
from contractor employees’ work as interrogators and interpreters at the Abu Ghraib prison 
complex,124 and the case also raises issues regarding the Alien Tort Statute that are outside the 
scope of this report. As to the combatant activities exception, the 
Saleh court first used the two-
prong analysis set forth in 
Boyle to find a unique federal interest in the detention and interrogation 
of individuals during war and a potentially significant conflict between this federal interest and 
the operation of state tort law.125 The court then broadened the “scope of displacement” test that 
had been used by the district court to find that claims are preempted “[d]uring wartime, where a 
private service contractor is integrated into combatant activities over which the military retains 
command authority.” The district court, in contrast, had found plaintiffs’ claims preempted only 
when the contractor is “under the direct command and exclusive operational control of the 
military chain of command,”126 a test that the D.C. Circuit found to be too narrow given that the 
“breadth of displacement must be inversely proportional to the states’ interests, just as it is 
directly proportional to the strength of the federal interest.”127 
                                                
121 Thus far, it seems like a minority of courts have found in favor of the defendant-contractor. 
See, e.g., Saleh v. Titan 
Corp., 580 F.3d 1 (D.C. Cir. 2009) (affirming that claims against defendants should be dismissed); 
Taylor, 2010 U.S. 
Dist. LEXIS 50610 (granting defendant’s motion to dismiss under the combatant activities exception). 
But see Bixby, 
2010 LEXIS 89717 (denying defendant’s motion to dismiss under the combatant activities exception); 
Harris, 618 F. 
Supp. 2d 400 (denying defendant’s motions to dismiss under the combatant activities exception); Lessin v. Kellogg 
Brown & Root, Inc., 2006 U.S. Dist. LEXIS 39403 (S.D. Tex. June 12, 2006) (same). 
122 648 F. Supp. 2d 994, 1006 (W.D. Tenn. 2008). It should be noted that the defendants in 
Flanigan did not explicitly 
assert the government contractor defense. However, the court stated that their argument for preemption was based on 
the analysis articulated in 
Boyle. 
Id. at 1004. The court then distinguished between the 
Koohi/ Bentzlin cases, which 
extended the 
Boyle defense to combatant activities because they concerned “complex equipment acquired by the 
Government,” and other cases that did not extend the exception because no manufacturing or design defects were 
alleged. 
Id. at 1006. The 
Flanigan court concluded that “the type of action at bar falls into the 
Koohi/Bentzlin category 
of cases, as the systems and components alleged by the Plaintiff ... constitute ‘complex equipment acquired by the 
Government.’”

Tort Suits Against Federal Contractors: An Overview of the Legal Issues 
 
Saleh and other recent decisions addressing the combatant activities exception highlight other 
apparent differences between the courts in their application of the exception, although it is unclear 
to what degree such differences influence the outcomes in particular cases given the widely 
different facts of the cases and other differences in courts’ approaches. Key among these 
differences are: 
•  
what constitutes a “combatant activity”: Some courts have adopted a broad 
definition of “combatant activity,” including “not only physical violence, but 
activities both necessary to and in direct connection with actual hostility.” 128 
Others have adopted narrower definitions. In 
Al Shimari v. CACI Inc., for 
example,129 the court defined “combatant activities” as “the actual engaging in 
the exercise of physical force.”130 Additionally, there is the related question of 
whether the court should focus solely upon whether the defendant’s actions fall 
within its definition of “combatant activities,” or whether it should first analyze 
whether the military actually retained control over the defendant’s actions, as the 
Saleh court did.131 
•  
whether the decisions in Koohi and Bentzlin are, in fact, based in Boyle and 
the combatant activities exception to the FTCA: Although several courts have 
addressed the application or non-application of the combatant activities exception 
through the 
Boyle government contractor defense analysis, a few courts have 
rejected this connection. For example, in 
McMahon v. Presidential Airways Inc., 
a federal district court declared that it was “skeptical that the combatant activities 
exception to the FTCA ... has any application to suits against private defense 
contractors.”132 The 
McMahon court not only pointed out the apparent conflation 
                                                             
(...continued) 
that the test “d[id] not protect the full measure of the federal interest embodied in the combatant activities exception.” 
Id. at 8. 
128 
See, e.g., 
Taylor, 2010 U.S. Dist. LEXIS 50610, at *28-20 (
citing Johnson v. United States, 170 F.2d 767 (9th Cir. 
1948)). In 
Taylor, the defendants argued that activities should be deemed combatant activities “whenever ‘contract 
employees [are] integrated into the military’s operational activities ... and perform[] a common mission with the 
military under ultimate military command.” 
Id. The plaintiffs argued that “the exception is limited to actual combat 
activities.” 
Id. 
See also Harris, 618 F. Supp. 2d 400 (denying the defendant-contractor’s motion to dismiss as it 
concluded, without much analysis, that the conduct giving rise to the claims in the case did not arise from active 
military combat operations). 
129 657 F. Supp. 2d 700. 
130 
Id. (
citing Skeen v. United States, 72 F. Supp. 372, 374 (W.D. La. 1947)). The court found that this more limited 
definition “comports with the common sense notion that a government contractor does not necessarily conduct 
combatant activities merely because it provides services in support of a war effort.” 
Id. While the court found that it 
could not conclude whether the defendant-contractor’s interrogation and interpretation services constituted “combat 
activities” prior to discovery, it analyzed the claims before it under the 
Boyle two-prong test and, unlike the court in

because the prosecution of war is a power constitutionally vested in the federal government. 
Id. at 721. The court 
specifically wanted to review the contract because, under its definition of “combat activities,” interrogation “should not 
properly be understood to constitute actual physical force ... because the amount of physical contact available to an 
interrogator is largely limited by law and by contract.”

of the government contractor defense and the combatant activities exception in 
Koohi and 
Bentzlin,133 but also noted that “[t]here is no express authority for 
judicially intermixing the government contractor defense and the combatant 
activities exception. ... [U]nless [private contractors] qualify as employees or 
agents of the Government, [they] may not bootstrap the Government’s sovereign 
immunity.”134 Other courts have noted similar problems in grounding the 
combatant activities exception in the government contractor defense.135 
•  
whether the government contractor defense bestows derivative sovereign 
immunity upon contractors: Not only have some courts taken the combatant 
activities exception and rooted it in the 
Boyle government contractor analysis, but 
at least one federal district court has suggested that the defense bestows 
derivative sovereign immunity upon contractors. In 
Bixby v. KBR, Inc., the court 
declared that “[u]nder the so-called ‘government contractor defense,’ where 
certain conditions are met, a government contractor enjoys derivative sovereign 
immunity against tort actions arising out of the contractor’s provisions of services 
to the government.”136 No other court appears to have adopted this analysis, 
although other defendants have asserted that they have derivative sovereign 
immunity, either because they are agents of the government or on other 
grounds.137 
As defendant-contractors assert with more frequency the government contractor defense and the 
combatant activities exception as grounds to preempt state tort law claims against them, it is 
possible that the distinction between the two defenses will become less, rather than more, clear.138

government employees.”

Bixby, 2010 U.S. Dist. LEXIS 89717. It should be noted that the 
Boyle Court explicitly stated that it did not address 
this issue. 
Boyle, 487 U.S. at 505 n1 (“The [dissent] misreads our discussion here to “intimat[e] that the immunity [of 
federal officials] ... might extend ... [to] nongovernment employees” such as a Government contractor. … But we do 
not address this issue, as it is not before us. We cite these cases [
Westfall v. Erwin, 
Howard v. Lyons, and 
Barr v. 
Matteo] merely to demonstrate that the liability of independent contractors performing work for the Federal 
Government, like the liability of federal officials, is an area of uniquely federal interest.”). Notwithstanding this 
discrepancy, the court in 
Bixby applied the three-part 
Boyle test to the claims at hand. 
Bixby separately addressed the 
combatant activities exception to the FTCA. Interestingly, although the court in 
Bixby stated that it would accept the 
Saleh rationale that the combatant activities exception precluded some claims against government contractors, it
 did not 
seem to acknowledge that the 
Saleh analysis was, in fact, grounded in the two-prong government contractor defense 
analysis from 
Boyle.

Tort Suits Against Federal Contractors: An Overview of the Legal Issues 
 
Though the result for the defendant-contractor might be the same regardless of the variation of 
the defense applied,139 what is asserted and how it is analyzed remain significant because of the 
scope of immunity at stake. Generally, each version of the government contractor defense140 
requires the defendant to meet a test fashioned by the court to determine (1) whether the defense 
is applicable in the first instance, and (2) if applicable, the scope for displacing state law. Moving 
across the spectrum (
see footnote 140), the scope of immunity generally seems to become broader 
as the specificities of the applicable test lessen. For example, one court stated that “[t]he 
combatant activities exception is much broader in scope than the discretionary function 
exception, and the 
Saleh degree of integration test may not appropriately limit the scope of the 
combatant activities exception as applied to government contractors.”141 Thus, depending on the 
type of defense asserted and recognized, a defendant-contractor may have a less burdensome 
affirmative defense to prove and a broader shield of immunity.142 
Derivative Immunity 
In some cases, contractors may assert derivative immunity that is not based in the government’s 
sovereign immunity, although contractors’ ability to assert such immunity 
does result from their 
working for the government. Derivative absolute immunity, which can protect government 
employees against certain tort suits, is one type of immunity that may be asserted. Contractors 
have also attempted to assert derivative 
Feres or “intramilitary” immunity, although with little 
success. Where a party is immune from suit, the court cannot exercise jurisdiction over the claim 
against it.  
                                                             
(...continued) 
Notwithstanding their disavowal of the government contractor defense and 
Boyle at this stage of the litigation, 
Defendants nevertheless rely on cases involving application of the 
Boyle-styled preemption defense ... Apparently 
puzzled ..., Plaintiffs interpret [the defendants’] combatant activities argument as a derivative sovereign immunity 
argument, not a preemption defense. ... The Court will assume for purposes of this motion the Defendants are 
raising a 
Boyle-styled, conflict preemption defense based on the combatant activities exception as opposed to a 
separate basis for the assertion of derivative sovereign immunity. 
Id. at 976. Similarly, in 
Lessin, the court noted that the defendant, in its motion to dismiss, emphasized that it was 
asserting the combatant activities exception rather than the affirmative government contractor defense laid out in 
Boyle.

140 The variety of defenses recognized thus far include: (1) the 
Boyle government contractor defense rooted in the 
discretionary function exception to the FTCA limited to military procurement contracts for goods; (2) the 
Boyle government contractor defense rooted in the discretionary function exception to the FTCA applicable to both contracts 
for services and goods; (3) the 
Boyle government contractor defense rooted in the combatant activities exception; and

 have chosen to look

Tort Suits Against Federal Contractors: An Overview of the Legal Issues 
 
Derivative Absolute Immunity 
Government employees are generally immune from suit when they perform “discretionary” (as 
opposed to ministerial) functions within the scope of their employment, and the court finds that 
the contributions of immunity to “effective government” within the particular context would 
outweigh the potential harm to individual citizens that might result from the employee’s being 
immune from suit.143 This type of immunity is known as “absolute immunity,” and it does not 
flow automatically from the government’s sovereign immunity, although it also operates to defeat 
the court’s jurisdiction.  
While the earliest decisions recognizing the doctrine of absolute immunity apparently were issued 
by the Supreme Court and address only government employees,144 more recent decisions by the 
lower courts have recognized that government contractors possess derivative absolute immunity 
in at least certain circumstances.145 These decisions can be read narrowly, as granting derivative 
absolute immunity to contractors only when they share information with the government or serve 
as a financial intermediary.146 However, one such decision by the U.S. Court of Appeals for the 
Fourth Circuit in 
Mangold v. Analytic Services, Inc., used particularly broad language in granting 
immunity to the contractor, suggesting that the “delegation” of functions to contractors is 
tantamount to delegation of functions to government employees: 
Extending immunity to private contractors to protect an important government interest is not 
novel. … If absolute immunity protects a particular government function, no matter how 
many times or to what level that function is delegated, it is a small step to protect that 
function when delegated to private contractors, particularly in light of the government’s 
unquestioned need to delegate government functions.147 
Contractors facing tort suits in contexts where courts have not previously granted them derivative 
absolute immunity have attempted to rely on the broad language of 
Mangold. They have also 
attempted to show that granting them immunity would comport with 
Westfall because they 
performed discretionary functions, and granting them immunity would contribute to effective 
government by, for example, ensuring that the government is free to contract out functions.148 
While such attempts to expand the contexts in which derivative absolute immunity exists have 
generally not succeeded, a few courts have accepted the argument that granting immunity to 
contractors contributes to effective government by protecting the government’s ability to contract

performing its duties); Mangold v. Analytic Servs., 77 F.3d 1442 (4th Cir. 1996) (contractor has absolute immunity for

Supreme Court’s unanimous decision in 
Westfall, which admonished courts to consider “whether the contribution to 
effective government in particular contexts outweighs the potential harm to individual citizens” in determining whether 
particular functions properly fall within the scope of absolute official immunity.

out functions, which it must do because it “cannot perform all necessary and proper services 
itself.”149  
Derivative Feres Immunity 
As noted previously, under the 
Feres doctrine, members of the military are barred from bringing 
suit against the U.S. government for “injuries [that] arise out of or are in the course of activity 
incident to service.”150 Although the 
Feres doctrine originally applied only when the service 
member was injured by another service member, it was subsequently expanded to encompass 
civilian employees of the government,151 and some government contractors have recently asserted 
that it should be further extended to provide derivative 
Feres or “intramilitary” immunity to at 
least some contractors. For example, in 
McMahon v. Presidential Airways, Inc., the contractors 
argued that they should share in the government’s 
Feres immunity because “‘the reality of 
modern warfare’ is such that contractors perform traditional military functions.”152 Although the 
contractors argued that the 
Feres doctrine should bar any claim by a plaintiff who is a member of 
the military,153 the Eleventh Circuit in 
McMahon refused to extend the doctrine to provide 
military contractors with immunity. Given that the Supreme Court expressly declined to expand 
the 
Feres doctrine so as to make it the basis for the government contractor defense when it 
decided 
Boyle,154 the Eleventh Circuit felt that it could not, consistently with 
Boyle, expand 
Feres 
here.  
Potential Indemnification of Contractor Liability 
An indemnification agreement is one in which one party to a contract agrees to hold the other 
party harmless, secure the other party against loss or damage, or give security for the 
reimbursement of the other party in the case of an anticipated loss.155 When the government has 
agreed to indemnify the contractor, the government, not the contractor, may be obligated to pay 
damages awarded to third parties in tort suits. An indemnification agreement does not allow a 
contractor to avoid liability for its torts, unlike the jurisdictional defenses previously discussed.156 
However, some commentators view an indemnification agreement as tantamount to avoiding 
liability because the contractor does not have to pay the costs of its actions or omissions.  
“Open-ended” indemnification agreements, of the type that would generally be necessary to cover 
damages for death or bodily injuries in tort, are arguably rare in government contracts.157

Tort Suits Against Federal Contractors: An Overview of the Legal Issues 
 
Agencies must have explicit statutory authority to enter such agreements because these 
agreements otherwise would run afoul of the Anti-Deficiency Act, which prohibits agencies from 
obligating funds in excess or advance of an appropriation.158 Public Law (P.L.) 85-804, which 
was enacted in the aftermath of the Korean War to allow agencies to provide various forms of 
“extraordinary contractual relief” in situations involving the “national defense,” has historically 
been the primary statutory authority that agencies rely upon when entering indemnification 
agreements.159 Only the military departments and specified civilian agencies, including the 
Atomic Energy Commission, the National Aeronautics and Space Administration, and the Federal 
Emergency Management Agency, may enter indemnification agreements under the authority of 
P.L. 85-804,160 and such agreements may only indemnify risks that are “unusually hazardous or 
nuclear,” as those risks are defined in the contract.161 However, other statutory provisions 
authorizing particular agencies to enter indemnification agreements also exist, most notably 
Section 4 of the Price-Anderson Act, which authorizes the Department of Energy to indemnify its 
contractors for claims arising from nuclear accidents,162 and since 2003, annual appropriations 
riders, which authorize the Department of the Army to provide “for such indemnification as the 
Secretary determines to be necessary.”163 Under an indemnification agreement, the government’s

potential liability. Agencies do not need express statutory authority to enter such agreements, although indemnification 
must still constitute a “necessary expense” upon which the agency may spend appropriated funds. 
See, e.g., Gov't 
Accountability Office, PRINCIPLES OF FEDERAL APPROPRIATIONS LAW, Vol. II, at 6-71 (3d ed. 2006) (“Indemnification 
agreements may be proper if they are limited to available appropriations.”). Such agreements can be broadly divided 
into two types. In the first type of agreement, the maximum potential amount of indemnification is known at the time of 
contracting, and funds sufficient to cover this contingent obligation can be reserved or recorded. 
See Vehicles—Charter 
Coach Service, B-164646 (Nov. 26, 1968) (approving of a government agreement to indemnify damages to leased 
buses caused by Selective Service registrants because the potential liability “was necessarily limited to the value of the 
motor carrier’s equipment”); Bailments—Liability, B-150729 (June 19, 1963) (approving of a government agreement 
to indemnify the owner of a leased aircraft for damages to the aircraft because the agency had no-year appropriations 
available to pay for such liability, and the “maximum liability was measurable by the fair market value of the aircraft”). 
In the second type of agreement, in contrast, the maximum potential amount of indemnification is not known at the 
time of contracting, but the contract limits the indemnification to the “availability of appropriated funds at the time a 
contingency occurs.” 48 C.F.R. § 52.228-7(d). 
See also Claim for Federal Reimbursement of State Disability Payments, 
B-202518 (Jan. 8, 1982). However, both the Government Accountability Office (GAO) and contractors have expressed 
discomfort with the second type of non-open-ended agreement. The GAO’s concerns center upon the “potentially 
disruptive fiscal consequences” that such agreements could have for agencies, while contractors are concerned that 
these agreements leave contractors at risk of not being fully indemnified for liability they might face. See PRINCIPLES OF

Tort Suits Against Federal Contractors: An Overview of the Legal Issues 
 
obligation to pay is often contingent upon certain conditions being satisfied, including, in the case 
of indemnification agreements entered into under P.L. 85-804, liability arising from those risks 
identified the contract.164 It is, thus, not unheard of for the government and the contractor to 
litigate whether the government is obligated, under the terms of the contract, to indemnify the 
contactor after the contractor is found to be liable.165  
At least one contractor facing tort suits has recently asserted that it has an indemnification 
agreement with the government which would cover any liability it owes in these suits.166 The 
merits of this claim cannot presently be assessed because the text of this indemnification clause is 
classified, and it is unclear whether the damages that allegedly occurred resulted from the risks 
that were addressed in the clause.167 The existence and potential terms of this agreement have 
generated substantial congressional interest, in part because the contractor who seeks to rely on 
the agreement could face suit by dozens, or even hundreds, of current and former members of the 
National Guard who served in Iraq for damages resulting from their exposure to sodium 
dichromate and subsequent hexavalent chromium poisoning.168  
Conclusion 
It remains to be seen how the issues raised by recent tort suits against federal contractors will play 
out in the courts and what, if any, changes in statutes, regulations, or policies the legislative or 
executive branches may make in response to court decisions. To date, congressional responses 
have centered upon ensuring that arbitration agreements do not bar claims arising under Title VII 
of the Civil Rights Act of 1964 or tort claims related to sexual assault or harassment and ensuring 
that lack of personal jurisdiction does not bar suits against foreign defendants for harms to U.S. 
persons occurring overseas.169 Other congressional responses to tort suits against government

Tort Suits Against Federal Contractors: An Overview of the Legal Issues 
 
contractors seek to hold contractors accountable for alleged wrongdoing by ensuring that they, not 
the government, pay any liability,170 as well as by excluding contractors who engage in tortious 
conduct that harms government personnel from government contracts171 and authorizing agencies 
to deny award fees to contractors found to have harmed government personnel.172 There do not, 
as yet, appear to have been any attempts to address, directly or indirectly, the barriers to subject 
matter jurisdiction that have apparently emerged; or otherwise clarify when contractors may 
avoid liability for tortious conduct because of the work they perform for the federal government.
