What it's about

The Supreme Court vacated the lower court’s ruling and sent the case back for reconsideration in light of Federal Republic of Germany v. Philipp, which addressed when the Foreign Sovereign Immunities Act allows such suits against foreign governments.

The dispute combines Holocaust-era property claims with the rules governing lawsuits against foreign governments in U.S. courts.

Question presented

May the district court abstain from exercising jurisdiction under the Foreign Sovereign Immunities Act for reasons of international comity, where former Hungarian nationals have sued the nation of Hungary to recover the value of property lost in Hungary during World War II, and where the plaintiffs made no attempt to exhaust local Hungarian remedies?

What the Court decided

Holding

Circuit is vacated, and the case is remanded for further proceedings consistent with the decision in Federal Republic of Germany v.

Result
Vacated

What's next

The case was sent back to the lower court (remanded) for further proceedings consistent with Federal Republic of Germany v. Philipp. Whether the survivors and heirs can recover in U.S. court remains unresolved.

Why it matters

The case now returns for further proceedings consistent with Federal Republic of Germany v. Philipp.
