The latest development in the long-running dispute over Germany's famed Guelph Treasure, and whether its 1935 sale by Jewish art dealers to the Prussian government was made under duress, could see the case before the US Supreme Court. Germany is challenging the case on jurisdictional grounds, claiming that it should not be decided in a US court.
In addition to the extensive media coverage the case has received, head of Sullivan's Art & Museum Law Practice Nick O'Donnell, who represents the heirs of the Jewish art dealers, has written extensively about the case's progression and the issue of Nazi-looted art generally in The Art Law Report:
