LOS ANGELES (AP) Seventy-nine years ago a Jewish woman named Lilly Cassirer surrendered her familys priceless Camille Pissarro painting to the Nazis in exchange for safe passage out of Nazi Germany during the Holocaust.
On Tuesday her great-grandson was in a U.S. courtroom for the latest round of what has been a nearly 20-year battle to get it back.
After years of appeals by both Lilly Cassirers descendants and Spains Thyssen-Bornemisza museum, where the painting has hung for 25 years, a trial to decide its rightful owner is scheduled before U.S. District Judge John F. Walter.
Neither side disputes that Cassirer handed the painting over to the Nazis in 1939 in exchange for safe passage out of the country for herself, her husband and her grandson.
But the Madrid museum has argued that she forfeited her ownership rights when she accepted $13,000 from Germany in 1958, after the German government concluded the painting was lost forever. The museum also has argued that it acquired the work in good faith and has never tried to hide it.
Cassirers attorney, David Boies, grilled defense witnesses while seeking to show that the museum should have known it was looted art.
Boies asked the museums legal and research team why they overlooked signs that indicated the provenance was questionable.
One of the museums experts, Lynn Nicholas, said she couldnt say if Baron Hans-Heinrich Thyssen-Bornemisza even looked at the back of the painting to study the provenance when he acquired it in 1976.
Nicholas said she couldnt explain why cardboard covering various labels showing provenance had been attached to the back of the artwork.
One of those labels showed it had belonged to a Berlin gallery owned by the Cassirer family.
Theres no dispute about the paintings complete history. The court examined all the evidence and determined that the museum is the rightful owner, Thyssen-Bornemiszas U.S. attorney, Thaddeus J. Stauber, told The Associated Press in 2016 after Walter initially dismissed the case.
The Cassirer family successfully appealed last year and their lawsuit was returned to Walter for trial.
The familys attorney, David Boies, says the matter now boils down to Spain doing whats right and surrendering the painting.
Its unusual for a modern liberal democracy to be trying to hold onto Nazi-looted art, he said Monday as he prepared for trial. Every other civilized country in the world is committed to returning Nazi-looted art to the rightful owners.
The painting, Rue St.-Honore, Apres-Midi, Effet de Pluie has been valued at $30 million or more.
