Italy’s highest court has ordered that a centerpiece of the Getty Villa’s art collection, a prized bronze sculpture more than 2,000 years old, should be returned to Italy in a ruling that could lead to a trans-Atlantic transfer or a diplomatic standoff.

The statue, named “Victorious Youth” but often referred to as the Getty Bronze, is on display at the villa on the outskirts of Los Angeles, which is part of the J. Paul Getty Museum. The bronze was retrieved from Adriatic waters by Italian fishermen in 1964. After a decade-long legal battle, Italy’s Court of Cassation ruled Monday that the statue should be confiscated and brought back to Italy, rejecting the Getty’s appeal. The decision had not been published Tuesday but a message from a court official describing it was provided to The New York Times.
