In a long-running legal fight over a Nazi-looted painting by Danish French Impressionist master Camille Pissarro, a federal judge in Los Angeles on Tuesday sided with the Spanish Foundation who currently holds the painting over the heirs who were seeking to reclaim it.

The parties in the case agreed that Lilly Cassirer Neubauer, the great-grandmother of the Cassirer plaintiffs, sold Pissarro’s “Rue Saint-Honoré, après-midi, effet de pluie” in 1939 after a Nazi-appointed art dealer seized it to conduct an appraisal and valued it at the modern equivalent of $360. The masterpiece since has been appraised at more than $30 million.
