Summary: written with AI from the case record.
What it's about
The Court ruled 6-3 for Exxon, holding that the Act itself removes foreign sovereign immunity for Cuban government agencies and instrumentalities, so plaintiffs do not also have to meet an exception in the Foreign Sovereign Immunities Act.
The decision says Congress clearly removed immunity for this category of Helms-Burton Act lawsuits, despite the Foreign Sovereign Immunities Act's general protection for foreign states.
Question presented
Does the Helms-Burton Act abrogate foreign sovereign immunity in cases against Cuban instrumentalities, even if the parties do not satisfy an exception under the Foreign Sovereign Immunities Act?
What the Court decided
Holding
The Helms-Burton Act itself abrogates the sovereign immunity of Cuban agencies and instrumentalities; plaintiffs who sue Cuban agencies or instrumentalities under the Act need not also satisfy one of 2 EXXON MOBIL CORP. v. CORPORACIÓN CIMEX, S. A. (CUBA) Syllabus FSIA’s enumerated exceptions to foreign sovereign immunity. A congressional waiver of sovereign immunity must be “clearly discernible from the sum total” of Congress’s “work,” Department of Agriculture Rural Development Rural Housing Service v. Kirtz, 601 U. S. 42, 55. 111 F. 4th 12, reversed and remanded.

- Reversed
The vote
From the opinions
“The answer should be just what the FSIA says: It depends on whether an FSIA exception is met.”
What's next
The case returns to the D.C. Circuit for further proceedings consistent with the Court's decision. Lower courts must apply the ruling when deciding whether Cuban agencies and instrumentalities are immune from Helms-Burton Act suits.
Why it matters
For example, a company alleging that such an entity used confiscated property does not also have to fit within a Foreign Sovereign Immunities Act exception.
