The Alien Tort Statute grants federal courts jurisdiction to hear cases involving violations of the law of nations.
While conceding that the ATS is strictly jurisdictional, we have also said that courts have narrow authority to create causes of action under it.
These positions are in obvious tension with one another.
More significantly, however, Asserting such authority would intrude on both Congress's prerogative to provide rights of action and the power of the political branches to direct the nation's foreign policy.
The authority to do so, always described as slight, is more accurately described as non-existent.
Today, We close the door that SOSA cracked and hold that courts may not create new causes of action for violations of international norms.
We also hold that the Torture Victim Protection Act of 1991, which contains an express cause of action, does not provide for aiding and abetting liability.
In the early days of our nation, two incidents involving foreign diplomats caused substantial foreign relations problems.
The French minister plenipotentiary complained to the Continental Congress and threatened to leave the country after the secretary of the French legation was assaulted in Philadelphia.
And a New York constable caused an international incident a few years later when he entered the house of the Dutch ambassador to arrest one of his servants.
At the time, the Articles of Confederation did not provide a federal forum to redress injuries like these.
But Secretary of Foreign Affairs John Jay cautioned that the federal government does not appear to be vested with any judicial powers competent to the cognizance and judgment of such cases.
Other leading figures were similarly troubled that the articles failed to provide for the case of offenses against the law of nations and consequently left it in the power of any indiscreet member to embroil the Confederacy with foreign nations.
Article III extends the judicial power to all cases affecting ambassadors, other public ministers and consuls, and to controversies between a state or the citizens thereof, and foreign states, citizens, or subjects.
The first Congress implemented these provisions through the Judiciary Act of 1789. which established lower federal courts and granted them jurisdiction to hear suits implicating foreign affairs.
The ATS grants federal district courts jurisdiction over 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.
The ATS lay mostly dormant after its enactment.
Litigants only occasionally invoked its jurisdictional grant.
And in time, another statute authorized federal courts to hear claims arising under treaties.
So for almost 200 years, the ATS did virtually no work.
That changed in 1980.
