Five years after striking down a California law that allowed a Jewish art dealer’s heir to sue to recover artwork stolen by the Nazis, a federal appeals court has reinstated the case.

Marei Von Saher claimed the Nazis stole a diptych—“Adam” and “Eve” by Lucas Cranach the Elder—from her late husband’s family when Germany invaded the Netherlands in 1940. She sued the Norton Simon Museum in Pasadena, where the paintings now hang.
