Exxon Mobil Corp. v. Corporación Cimex, S. A. (Cuba)
The Court ruled that a 1996 law letting Americans sue over property Cuba confiscated after Castro's takeover already strips Cuban state companies of their usual immunity from U.S. lawsuits, so plaintiffs like Exxon don't need to clear a separate immunity test that would have made most such suits nearly impossible.
The decision revives Exxon's billion-dollar lawsuit over its seized oil refinery and stations, and more broadly opens the door for Americans to sue Cuban government companies over confiscated property without meeting requirements that Cuba's own trade embargo made almost impossible to satisfy.
How it got here: A federal trial court dismissed Exxon's suit on immunity grounds and a divided D.C. Circuit panel affirmed; Exxon asked the Supreme Court to review.
The Case in Depth
What happened
After Fidel Castro took power in Cuba in 1959, his government confiscated Exxon's oil refinery, terminals, and more than a hundred service stations, later transferring them to Cuban state-owned companies CUPET and CIMEX. In 1996 Congress passed the Helms-Burton Act, letting Americans whose property was seized sue those responsible. Exxon sued the Cuban companies seeking over $1 billion.
The question before the Court
Can Exxon sue Cuban state-owned companies over property Castro's government seized in 1960, without also meeting the separate legal test that normally shields foreign governments from U.S. lawsuits?
The Court's answer
Yes — the Court ruled that the Helms-Burton Act itself removed Cuban state companies' usual immunity from lawsuits, so Exxon does not need to separately satisfy the Foreign Sovereign Immunities Act's exceptions. The Court found four features of the law worked together to make this clear: it creates a lawsuit right that explicitly targets government-owned Cuban entities, it would be pointless if plaintiffs also had to meet immunity exceptions Cuba's own embargo made nearly unreachable, it routes these suits through the general federal-question statute rather than the one used for foreign-government suits, and it gives the President ongoing power to pause these suits much like pre-1976 practice, when the Executive Branch (not a fixed legal test) controlled immunity.
Together, these signals were enough for the Court to conclude Congress's intent to strip immunity was "clearly discernible," even without an explicit statement. The ruling revives Exxon's suit but leaves open whether the same result applies to non-Cuban foreign companies.

Why it matters
Americans and companies whose property was confiscated by Cuba can now pursue lawsuits against Cuban government-owned businesses without proving the kind of direct U.S. commercial activity the general foreign-immunity law would otherwise require — a bar the embargo itself made nearly unreachable. That could expose Cuban state enterprises to significant financial judgments and affect U.S.-Cuba relations.
What changes now
The case goes back to the lower courts, where Exxon's lawsuit against the Cuban companies can now proceed without Exxon needing to satisfy the general immunity law's exceptions. This is a final merits ruling on the immunity question, though further proceedings will address the remaining merits of Exxon's billion-dollar claim. The Court expressly left open whether the same reasoning extends to lawsuits against other countries' state companies.
What this does not decide
The Court expressly did not decide whether the Helms-Burton Act also strips immunity from other countries' government-owned companies, only Cuba's. It also did not resolve whether Exxon could ultimately collect any money judgment, since a separate immunity rule protects foreign government property from being seized to pay judgments.

How the Justices voted
Majority (6). Justice Kavanaugh (author), joined by Justice Roberts, Justice Thomas, Justice Alito, Justice Gorsuch, and Justice Barrett.
Dissent (3). Justice Kagan (author), joined by Justice Sotomayor and Justice Jackson.
Dissent — Justice Kagan
Justice Kagan argued the bar for finding Congress stripped a foreign government's immunity is high and unmet here, since the Helms-Burton Act never mentions immunity while it did amend a different immunity provision (execution immunity), showing Congress knew how to change immunity rules when it wanted to. She noted Congress considered and rejected an explicit immunity-stripping amendment, and the cause of action still has plenty of work to do suing private traffickers and instrumentalities that meet an existing immunity exception, so nothing is negated by leaving immunity intact.

How the Court got there
The legal reasoning, step by step
- The Court applied its rule that a congressional waiver of a foreign government's immunity from lawsuits must be 'clearly discernible' from everything Congress wrote, without needing to use any specific magic words.
- First, the Court noted that under its precedents, when Congress creates a lawsuit right that explicitly can be brought against a government entity, that alone signals Congress removed that entity's immunity, even without a separate immunity-waiver clause.
- Second, the Court reasoned that Congress does not usually create a right to sue while simultaneously making it practically impossible to use; because Cuba's own trade embargo (created by the same law) would block plaintiffs from meeting the general immunity law's exceptions, requiring plaintiffs to meet those exceptions would gut the right to sue that Congress created.
- Third, the Court pointed to the law's own text routing these lawsuits through the general federal-question statute (28 U.S.C. §1331) rather than the specific statute used for suits against foreign governments (§1330), taking that as a sign Congress meant the general immunity law not to apply.
- Fourth, the Court found that giving the President ongoing power to pause these lawsuits for national-security or foreign-policy reasons mirrored how immunity questions were handled before the general immunity law existed, when the Executive Branch — not judges applying a fixed legal test — controlled immunity decisions.
- Putting these four features together, the Court concluded that Congress had made clear enough, through the law's overall structure, that it removed Cuban state companies' immunity from these particular lawsuits.
