What it's about

The dispute concerned whether plaintiffs could instead mail the papers through Sudan’s embassy in Washington, D.C., in a case involving a $314 million default judgment against Sudan.

The case balanced a U.S. law on serving foreign governments against protections for diplomatic missions under the Vienna Convention.

Question presented

Whether the Second Circuit erred by holding - in direct conflict with the D.C., Fifth, and Seventh Circuits and in the face of an amicus brief from the United States - that plaintiffs suing a foreign state under the Foreign Sovereign Immunities Act may serve the foreign state under 28 U.S.C § 1608(a)(3) by mail addressed and dispatched to the head of the foreign state's ministry of foreign affairs "via" or in "care of” the foreign state's diplomatic mission in the United States, despite U.S. obligations under the Vienna Convention on Diplomatic Relations to preserve mission inviolability.

What the Court decided

Holding

Most naturally read, §1608(a)(3) requires a mailing to be sent directly to the foreign minister’s office in the foreign state. 802 F. 3d 399, reversed and remanded.

From the opinions

“This bright-line rule may be attractive from a policy perspective, but the FSIA neither specifies nor precludes the use of any particular address.”

— Justice Thomas(dissent)

What's next

The case returns to the lower court for further proceedings under the Supreme Court's rule on service. The Supreme Court did not resolve the underlying claims in this ruling.
