A team of attorneys from Foley Hoag and Amineddoleh & Associates won a ruling on behalf of Greece in a fight over the ownership of an 8th century B.C. bronze horse sculpture.

In 2018, Sotheby's announced it planned to auction the sculpture on behalf of the 2012 Saretta Barnet Revocable Trust. Greece's Ministry of Culture and Sports then informed the auction house that according to Greece's patrimony laws, the sculpture is the property of the Greek state, appears to have been illegally removed from Greek territory, and should be returned to Greece rather than sold. The trustees and Sotheby's sued Greece in the Southern District of New York seeking declaratory relief on the disputed issue of ownership. Greece filed a motion to dismiss for lack of jurisdiction, arguing sovereign immunity.

Foley's Andrew Schwartz and Constantinos Salonidis along with Leila Amineddoleh of Amineddoleh & Associates convinced the U.S. Court of Appeals for the Second Circuit to reverse the district court decision. The Second Circuit, in a decision by Judges Gerard Lynch, Peter Hall and Steven Menashi, held that the enactment and enforcement of patrimony laws are sovereign rather than commercial activities, and the court therefore lacked jurisdiction under the Foreign Sovereign Immunities Act to hear the case.
