a U.S. appeals court in California ruled in one of the oldest Nazi art theft cases
French impressionist Camille Pissarro's 'Rue Saint Honore, apres-midi, effet de pluie'
was stolen in 1939 from Lilly Neubauer, a Jewish woman who lived in Germany
Ownership passed through several hands until 1993
when Madrid's Thyssen-Bornemisza museum bought the painting
Neubauer's grandson, Claude Cassirer, petitioned for its return in 2001
and sued the museum in U.S. District Court in California four years later
