A lawsuit between the heirs of master Expressionist painter George Grosz and New York's Museum of Modern Art has implications for international law, the New York Times reports.
Martin and Lilian Grosz, the painter's son and daughter-in-law, initially sued the museum in 2003, requesting the return of three paintings they allege were stolen by the Nazis before coming into MOMA's possession.
After consulting with experts, the museum rejected the claim, arguing there is no evidence the artworks were looted by the Nazis.
