ATS Jurisdiction in U.S.-Controlled Occupation Detention Facilities and Corporate Conspiracy Liability for Torture/CIDT

Introduction

Suhail Al Shimari v. CACI Premier Technology, Inc. (4th Cir. Mar. 12, 2026) is the Fourth Circuit’s latest—and merits-dispositive—decision in long-running litigation arising from detainee abuses at Abu Ghraib during the Iraq War. The plaintiffs, Iraqi citizens, sued a U.S. defense contractor, CACI Premier Technology, Inc. (“CACI”), under the Alien Tort Statute (“ATS”), alleging they were tortured and subjected to cruel, inhuman, and degrading treatment (“CIDT”) by U.S. military police as part of a conspiracy with CACI interrogators intended to “soften up” detainees for interrogation.

After a mistrial and a retrial, a jury found CACI liable for conspiracy to commit torture and conspiracy to commit CIDT, awarding each plaintiff $3 million in compensatory damages and $11 million in punitive damages. On appeal, CACI pressed threshold objections—ATS extraterritoriality, cognizability of claims, derivative sovereign immunity, political question, FTCA “combatant activities” preemption, state secrets—as well as merits challenges (sufficiency, borrowed-servant defense, evidentiary rulings) and damages challenges. CACI also appealed rulings involving its third-party claims against the United States.

Summary of the Opinion

  • ATS jurisdiction affirmed. The majority holds the case does not fail on extraterritoriality grounds under multiple independent theories: (i) Abu Ghraib detention facilities during the CPA period were within the United States’ “territorial jurisdiction” per Rasul v. Bush; (ii) even if not, the conduct occurred beyond any sovereign’s territorial jurisdiction and torture is analogous to piracy in Kiobel v. Royal Dutch Petrol. Co.; and (iii) alternatively, sufficient domestic conduct relevant to the ATS’s focus occurred in the U.S. under Nestlé USA, Inc. v. Doe.
  • ATS causes of action upheld. The court recognizes ATS conspiracy liability (joining the Eleventh Circuit’s position) and confirms corporate defendants may be sued under the ATS, aligning with concurrences in Nestlé USA, Inc. v. Doe.
  • Threshold defenses rejected. No derivative sovereign immunity (CACI failed to show the government authorized the specific unlawful conduct); political question doctrine does not bar adjudication of unlawful torture/CIDT; FTCA combatant-activities exception does not preempt ATS claims; state secrets did not require dismissal because CACI could still pursue core defenses.
  • Merits affirmed. Admission of the Taguba and Fay reports upheld under Fed. R. Evid. 803(8); evidence sufficient to sustain conspiracy verdict; borrowed-servant defense properly instructed and reasonably rejected by the jury.
  • Damages affirmed. Compensatory and punitive awards upheld; Virginia punitive-damages cap held inapplicable to this federal-ATS case.
  • Third-party claims against U.S. vacated and remanded with instructions to dismiss. The panel holds the United States is immune (ATS is jurisdictional only and does not waive sovereign immunity), vacates the district court’s sovereign-immunity denial and summary judgment ruling, and remands to dismiss on sovereign immunity grounds, citing Goldstar (Panama) S.A. v. United States.

Disposition: “Affirmed in part, vacated in part, and remanded with instructions.”

Analysis

Precedents Cited

1) ATS framework and extraterritoriality

  • Sosa v. Alvarez-Machain supplies the foundational modern ATS test: the ATS is “jurisdictional,” but permits federal courts to recognize limited causes of action for violations of international norms that are accepted by the civilized world and defined with specificity comparable to 18th-century paradigms. The court uses Sosa both to (i) describe the ATS’s intended “practical effect” and (ii) justify recognition of modern claims where norms are definite.
  • Kiobel v. Royal Dutch Petrol. Co. provides the presumption against extraterritoriality as applied to ATS claims and the (now-superseded in part) “touch and concern” language. The majority leans on Kiobel in two ways: (i) acknowledging the presumption, and (ii) emphasizing Kiobel’s piracy discussion to develop a “piracy/torture” analogy when conduct occurs beyond any sovereign’s jurisdiction.
  • Nestlé USA, Inc. v. Doe reframes domestic-application analysis: plaintiffs must show “the conduct relevant to the statute’s focus occurred in the United States,” and “general corporate activity” cannot alone establish domestic application. The majority narrows its earlier reasoning in Al Shimari v. CACI Premier Tech., Inc. (Al Shimari III) to exclude generic corporate contacts, but finds domestic conduct still relevant because the Convention Against Torture imposes affirmative prevention/training duties that make CACI’s U.S.-based hiring, clearance, and response to abuse reports legally salient.
  • RJR Nabisco, Inc. v. European Cmty. supplies the “conduct relevant to the statute’s focus” formulation later used in Nestlé.
  • Abitron Austria GmbH v. Hetronic Int'l, Inc. is cited to reaffirm the modern two-step extraterritoriality framework and the “focus” inquiry.
  • Rasul v. Bush (and Foley Bros., Inc. v. Filardo) anchors the majority’s most novel move: that U.S. “complete jurisdiction and control” can bring a place outside the fifty states within the United States’ “territorial jurisdiction,” making the presumption inapplicable. The majority extends this logic from habeas to the ATS, finding CPA Orders (especially CPA Order 10) created U.S. plenary control over Iraqi detention facilities from June 2003 to June 2004.
  • The majority distinguishes and declines to follow Adhikari v. Kellogg Brown & Root, Inc. (5th Cir.) and Al Maqaleh v. Gates (D.C. Cir.)—both of which refused to treat overseas facilities in Iraq/Afghanistan as within U.S. territorial jurisdiction—emphasizing timing (CPA period) and the specific CPA detention-facility control structure.
  • Morrison v. Nat'l Austl. Bank Ltd. is used as a warning that domestic “contacts” alone cannot defeat the presumption; the majority attempts to satisfy Morrison by tying domestic conduct to the ATS’s focus (international-law violations and their prevention duties).

2) Recognizing conspiracy and corporate liability under the ATS

  • Jesner v. Arab Bank, PLC is used for ATS “judicial caution” (Sosa step two) and separation-of-powers sensitivity. The majority reads Jesner as allowing recognition of ATS claims where foreign-relations concerns are minimal and Congress’s TVPA history supports ATS torture remedies.
  • Doe v. Drummond Co., Inc. (11th Cir.) is the only circuit authority the panel identifies as expressly recognizing ATS conspiracy liability; the panel adopts that view.
  • The court’s survey of international sources to support conspiracy/complicity includes: The Paquete Habana (sources of international law); the Agreement for the Prosecution and Punishment of Major War Criminals of the European Axis, and Establishing the Charter of the International Military Tribunal (London Charter); Khulumani v. Barclay Nat'l Bank Ltd. and Presbyterian Church of Sudan v. Talisman Energy, Inc. (secondary liability in international law); the ICTY/ICTR statutes; the Rome Statute; and the Convention Against Torture.
  • Corporate liability is grounded largely in five justices’ views in Nestlé USA, Inc. v. Doe, particularly Justice Gorsuch’s concurrence that the ATS’s text does not create corporate immunity and that early ATS purposes would not turn on the defendant’s organizational form.

3) Immunities, justiciability, preemption, and state secrets

  • Goldstar (Panama) S.A. v. United States controls the United States’ sovereign immunity: ATS does not waive sovereign immunity; independent consent is required. The panel vacates the district court’s contrary approach and orders dismissal of CACI’s third-party claims against the United States.
  • Derivative sovereign immunity doctrine is drawn from Yearsley v. W.A. Ross. Constr. Co., In re KBR, Inc., Burn Pit Litig., and Campbell-Ewald Co. v. Gomez, with additional context from Filarsky v. Delia. The key requirement: the government must have authorized the specific conduct, and the contractor must have adhered to government instructions.
  • Political question doctrine analysis follows Baker v. Carr through this circuit’s contractor-specific framing in Taylor v. Kellogg Brown & Root Servs., Inc., and the court’s prior case-specific rulings in Al Shimari III and Al Shimari IV. The majority’s controlling principle from Al Shimari IV: unlawful conduct (torture/CIDT) is justiciable even if the military exercised control; legality—not “reasonableness”—is for courts, citing Marbury v. Madison and referencing Boumediene v. Bush and Hamdan v. Rumsfeld.
  • FTCA combatant-activities preemption is addressed through Hencely v. Fluor Corp., Saleh v. Titan Corp., and Boyle v. United Technologies Corp., but the majority rejects applying Boyle-style state-law preemption logic to ATS federal-common-law claims. Instead it applies federal-common-law displacement principles from County of Oneida v. Oneida Indian Nation, City of Milwaukee v. Illinois, United States v. Texas, Pond v. United States, and Fairfax's Devisee v. Hunter's Lessee.
  • State secrets doctrine is discussed through Totten v. United States, El-Masri v. United States, Wikimedia Foundation v. National Security Agency, Abilt v. CIA, and Fitzgerald v. Penthouse Int'l, Ltd.. The majority’s practical line: dismissal is warranted only where privileged information makes the case incapable of fair litigation; here, trial proceeded without disclosure of secrets and CACI could pursue core defenses.

4) Trial and damages rules applied

  • Evidentiary admissibility of the Taguba/Fay reports relies on Fed. R. Evid. 803(8) and Beech Aircraft Corp. v. Rainey, with trustworthiness factors from Distaff, Inc. v. Springfield Contracting Corp. and related authorities (Zeus Enters., Inc. v. Alphin Aircraft, Inc., English v. District of Columbia, Combs v. Wilkinson, Chavez v. Carranza).
  • Conspiracy responsibility principles are illustrated by Pinkerton v. United States.
  • Borrowed-servant/control standards cite Standard Oil Co. v. Anderson, the Restatement (Third) of Agency, and circuit precedent including Est. of Alvarez v. Rockefeller Found..
  • Punitive damages due-process discussion invokes Weeks v. Angelone as to jury-instruction presumptions; the cap issue is distinguished from Sines v. Hill because that was state-law liability.

Legal Reasoning

1) The majority’s multi-track ATS jurisdiction holding

The opinion is structured to survive extraterritoriality challenges under several independent rationales:

  1. “Territorial jurisdiction” via CPA control (Rasul extension). The majority finds that CPA Orders—especially CPA Order 10 vesting “full authority and control” over detention facilities under CPA administration—made Abu Ghraib effectively within U.S. “territorial jurisdiction” during the relevant period (Oct–Dec 2003). By analogizing to Rasul v. Bush (Guantanamo), it reasons the presumption against extraterritoriality “has no application” when the U.S. has “complete jurisdiction and control.”
  2. “No other sovereign” + torture-as-piracy (Kiobel gloss). Even if Iraq was not within U.S. territorial jurisdiction, the majority portrays late-2003 Iraq as effectively outside any sovereign’s territorial jurisdiction given the deposed regime and the CPA’s plenary authority. It then builds on Kiobel’s piracy discussion: because pirates operate beyond sovereign territory and applying U.S. law to them avoids imposing U.S. will on another sovereign, similar reasoning supports ATS jurisdiction for torture—treated as a modern hostis humani generis norm with universal jurisdiction obligations (supported by the Convention Against Torture and Filartiga v. Pena-Irala).
  3. Domestic application under Nestlé via “affirmative prevention” norms. Recognizing that Nestlé USA, Inc. v. Doe narrowed what counts as relevant domestic conduct (excluding “general corporate activity”), the majority recharacterizes CACI’s U.S.-based conduct (hiring, clearance, and reaction to reports/cover-up) as conduct directly tied to the ATS’s focus because international anti-torture law imposes affirmative prevention/training/review obligations. That framing allows the court to treat domestic omissions and decisions not as generic corporate operations but as internationally salient failures to prevent torture.

2) Conspiracy and corporate liability as cognizable ATS claims

Applying the Sosa/Jesner two-step framework, the majority concludes:

  • Sosa step one (definite international norm): conspiracy/complicity modes of liability are “well established” in international-law instruments and post-WWII tribunals; therefore, conspiracy to commit torture/CIDT rests on sufficiently specific, universal norms.
  • Sosa step two (judicial discretion/separation of powers): the court treats this as a “paradigmatic” ATS case: U.S. actors, U.S. contractor, universally condemned conduct, and minimal risk of adjudicating foreign sovereign conduct—thus, less foreign-relations intrusion than typical ATS litigation. It further leans on TVPA legislative history as congressional approval that ATS torture claims exist.
  • Corporate liability: the court adopts the view that the ATS’s text does not distinguish between corporate and natural-person defendants, and that ATS purposes (avoiding international incidents by providing a U.S. forum) are not furthered by exempting corporations.

3) Threshold defenses fail because the conduct is unlawful and unauthorized

  • Derivative sovereign immunity: under Yearsley/Burn Pit/Campbell-Ewald, authorization must be specific and adhered to; CACI did not argue (and could not show) the government authorized unlawful torture/CIDT conspiracy conduct, so the defense fails.
  • Political question doctrine: under Al Shimari IV, even where military control is shown, unlawful conduct is justiciable; the jury necessarily found unlawful torture/CIDT occurred under the court’s instructions, so Taylor/Baker concerns do not bar adjudication.
  • FTCA combatant-activities exception preemption: the court treats Hencely/Boyle as state-law preemption doctrine and refuses to extend it to ATS federal-common-law claims, applying instead the displacement inquiry from County of Oneida and City of Milwaukee v. Illinois.
  • State secrets: applying El-Masri and Wikimedia, the majority finds CACI still could contest whether plaintiffs were abused, could present witnesses (even via pseudonymous/telephonic depositions), and could press defenses; the case was not “incapable of judicial resolution.”

4) Trial rulings and damages: deference plus doctrine

The majority applies substantial deference to evidentiary rulings and jury determinations. It upholds admission of the Taguba and Fay reports as trustworthy “public office” investigative findings under Rule 803(8), rejects sufficiency challenges given testimonial and report evidence of “setting conditions,” and affirms rejection of the borrowed-servant defense based on evidence of CACI supervisory capacity on the ground. On damages, it holds the compensatory and punitive awards fit the gravity of torture/CIDT and declines to import a Virginia punitive cap into a purely federal cause of action.

Impact

  • Expanded ATS “domestic” space via occupation governance. By treating CPA-controlled Iraqi detention facilities (June 2003–June 2004) as within U.S. “territorial jurisdiction,” the decision creates a potentially significant pathway for ATS jurisdiction where the United States exercises plenary governmental control abroad—even absent formal sovereignty. This is likely to be cited in future litigation over U.S.-run detention or governance zones.
  • New Fourth Circuit recognition of ATS conspiracy liability (and solidification of corporate liability). The opinion expressly embraces conspiracy as cognizable under the ATS and rejects corporate immunity. This will matter in contractor, supply-chain, and security-service cases where direct perpetration is hard to prove but agreement/coordination is alleged.
  • Limits on contractor immunities in atrocity contexts. The court reinforces that derivative sovereign immunity requires proof of specific authorization and adherence; contractors cannot rely on “umbrella” wartime integration if the conduct is unlawful.
  • Reduced force of FTCA combatant-activities preemption against ATS claims. By separating Boyle-style preemption (state tort law) from ATS federal-common-law displacement, the opinion undermines arguments that Saleh v. Titan Corp. and similar frameworks automatically foreclose ATS suits involving combat zones.
  • State secrets doctrine applied as a functional “fair litigability” test. The decision emphasizes whether core claims/defenses can be tried without privileged material, potentially encouraging courts to manage rather than dismiss—even in sensitive cases—where trial can proceed without disclosure.
  • Prospects for further review. The dissent frames the decision as unprecedented expansions on extraterritoriality, conspiracy, and separation-of-powers caution. Given existing inter-circuit tensions (e.g., Adhikari v. Kellogg Brown & Root, Inc.) and the Supreme Court’s continuing ATS scrutiny (including the opinion’s mention that certiorari was granted in Doe I v. Cisco Sys., Inc.), the ruling is positioned for potential higher-court review.

Complex Concepts Simplified

  • Alien Tort Statute (ATS): a jurisdiction statute allowing non-U.S. plaintiffs to sue in U.S. federal court for certain violations of international law (“law of nations”), but only for a narrow set of well-defined norms.
  • Presumption against extraterritoriality: courts presume U.S. statutes apply only inside the U.S. unless Congress clearly says otherwise. Under RJR Nabisco, Inc. v. European Cmty. and Nestlé USA, Inc. v. Doe, courts ask whether the statute’s “focus” occurred domestically.
  • “Territorial jurisdiction” vs. sovereignty: a place can be outside formal U.S. sovereignty yet still be treated as within U.S. territorial jurisdiction if the U.S. exercises complete control (the majority analogizes Abu Ghraib during CPA rule to Guantanamo in Rasul v. Bush).
  • Jus cogens and universal jurisdiction: certain norms (like torture) are so fundamental that international law treats them as universally condemnable; some treaties (e.g., the Convention Against Torture) require states to assert jurisdiction over alleged torturers found in their territory.
  • Conspiracy liability: liability based on an agreement to commit wrongful acts; a conspirator can be held responsible for acts committed by other conspirators in furtherance of the scheme (the opinion analogizes to Pinkerton v. United States).
  • Derivative sovereign immunity (Yearsley immunity): contractors can share the government’s immunity only when the government specifically authorized the actions and the contractor followed instructions; unlawful or unauthorized deviations are not protected.
  • Political question doctrine: courts avoid issues constitutionally committed to political branches, but the opinion stresses that unlawful torture/CIDT is a legal question courts can decide.
  • State secrets privilege: protects sensitive national-security information from disclosure; cases can be dismissed only if the privilege prevents fair litigation (e.g., where defenses cannot be mounted without secret evidence).
  • Borrowed servant doctrine: determines whether an employee’s work was controlled by a “special employer” (here, the Army) rather than the “general employer” (CACI), affecting which entity bears responsibility.

Conclusion

The Fourth Circuit’s decision is a major ATS ruling with two headline contributions: (1) it substantially widens the set of circumstances in which ATS claims can be treated as “domestic” by treating CPA-controlled Iraqi detention facilities as within U.S. territorial jurisdiction (or, alternatively, as outside any sovereign’s territory for purposes of torture-as-piracy reasoning), and (2) it endorses ATS liability for corporate conspiracy to commit torture and CIDT, rejecting multiple wartime contractor defenses (immunity, political question, FTCA preemption, state secrets) on the record developed through two trials.

The dissent underscores how far-reaching these moves may be, particularly under Kiobel v. Royal Dutch Petrol. Co. and Nestlé USA, Inc. v. Doe. Regardless of ultimate appellate fate, the opinion meaningfully reshapes the Fourth Circuit’s ATS landscape for contractor-linked abuses in U.S.-controlled overseas detention contexts and provides a detailed roadmap for litigating (and resisting) common threshold defenses in national-security-adjacent civil human-rights cases.
