Understanding the Alien Tort Statute (ATS)

The Alien Tort Statute (ATS), also known as the Alien Tort Claims Act (ATCA), stands as one of the oldest federal statutes in the United States, dating back to the Judiciary Act of 1789. For nearly two centuries, this law remained largely dormant. However, since 1980, it has been recognized as a critical mechanism for foreign nationals—or “aliens”—to seek justice in U.S. federal courts for severe human rights abuses committed overseas.

The law’s text is simple, yet its interpretation is complex: “The district courts shall have original jurisdiction of any civil action by an alien for a tort only, committed in violation of the law of nations or a treaty of the United States” (28 U.S.C. § 1350). The original purpose was to promote international harmony and ensure a remedy for violations of international law, preventing foreign nations from holding the United States accountable for unredressed injuries to their citizens.

The Three Core Elements of an ATS Claim

To successfully invoke jurisdiction under the ATS, a plaintiff must establish three key elements:

1. The Plaintiff is an Alien: The suit must be a civil action by an alien (a non-U.S. national). The statute does not provide jurisdiction for U.S. nationals to sue.
2. The Action is for a Tort: The lawsuit must concern a tort, which is a civil wrong (other than a breach of contract) for which a remedy, usually damages, can be obtained.
3. Violation of International Law: The tort must be committed in violation of the law of nations or a treaty of the United States.

The most critical element is the violation of the ‘law of nations.’ Following the landmark Supreme Court decision in Sosa v. Alvarez-Machain (2004), a plaintiff must demonstrate that the violation is of an international norm that is “specific, universal, and obligatory”. Courts have recognized norms prohibiting torture, genocide, war crimes, crimes against humanity, and summary execution as actionable under the ATS.

Landmark Cases Defining the Statute’s Scope

The ATS experienced a dramatic rebirth in 1980, followed by a series of restrictive Supreme Court rulings that have dramatically narrowed its application.

Case 1: The Revitalization – Filártiga v. Peña-Irala (1980)

Case 2: Specificity and Universality – Sosa v. Alvarez-Machain (2004)

The Supreme Court affirmed that the ATS permits suits for violations of modern international law, but simultaneously placed limits. It held that federal courts could only hear a “narrow set” of claims for violations of international law, requiring the norm to be as “specific, universal, and obligatory” as the original 18th-century offenses (e.g., piracy and violation of diplomatic rights).

Case 3: Extraterritoriality – Kiobel v. Royal Dutch Petroleum Co. (2013)

In a major restriction, the Court held that the presumption against applying U.S. laws extraterritorially extends to ATS claims. This meant that ATS lawsuits based purely on conduct that occurred abroad—with no sufficient U.S. connection—were precluded. The claim must “touch and concern” U.S. territory with “sufficient force”.

The Current Viability of the ATS

Despite the significant restrictions imposed by the Supreme Court over the last two decades, the ATS is not entirely defunct. For plaintiffs, the path to justice in a U.S. federal court is much narrower, requiring a provable connection between the actionable tort and conduct occurring domestically.

Today, the ATS continues to be a subject of intense debate among legal expert scholars and human rights advocates. While direct recovery in some cases has been limited, the lawsuits themselves serve a critical function: to provide a forum for victims to be heard and bring international attention to the harms they have suffered. This is particularly important in contexts where local legal systems are unwilling or unable to provide justice against powerful corporate or government entities.

Summary: Key Takeaways on the ATS

1. The ATS (28 U.S.C. § 1350) grants U.S. federal courts jurisdiction over civil actions filed by non-U.S. citizens for torts that violate the law of nations or a U.S. treaty.
2. The actionable international norm must be ‘specific, universal, and obligatory’, as established in Sosa v. Alvarez-Machain.
3. The Supreme Court’s decisions, notably in Kiobel and Nestlé, heavily restrict the statute’s extraterritorial application and have effectively ruled out liability for foreign corporations and limited claims against domestic corporations for overseas conduct.
4. While narrowed, the ATS remains a historic tool for victims of atrocities like torture, genocide, and war crimes to seek justice in the U.S. legal system.

Frequently Asked Questions (FAQ)

Q: Can a U.S. citizen file a lawsuit under the Alien Tort Statute?

A: No. The statute explicitly limits the jurisdiction of federal courts to a civil action by an alien (a non-U.S. national). U.S. citizens who have suffered similar harms must rely on other domestic or international statutes for their claims.

Q: What does ‘committed in violation of the law of nations’ mean?

A: This phrase refers to a violation of international norms that are “specific, universal, and obligatory”. In modern context, this includes international human rights abuses such as torture, genocide, war crimes, and prolonged arbitrary detention. Simple violations of general human rights principles (e.g., a generalized “right to health”) are generally not considered actionable.

Q: Can I sue a foreign company under the ATS?

A: Following the Supreme Court’s ruling in Jesner v. Arab Bank, PLC (2018), foreign corporations may not be held liable as defendants in suits brought under the ATS.

Q: Does the tort have to happen in the United States?

A: Not entirely, but it must have a sufficient connection to the United States. The Supreme Court applies a presumption against extraterritoriality, meaning a claim cannot proceed if the conduct that directly caused the injury occurred entirely overseas, unless it can be shown that the conduct “relevant to the statute’s focus occurred in the United States”. This is a high legal hurdle to clear.
