Isn’t the purchase of these works art by old Gurlitt kind of like imminent domain?
imminent or eminent — I don’t understand your point
Seems like a transfer of title to me. There could well be a recision claim by the original owners, who sold under duress, but there is usually a statute of limitations for such claims. Also, the law is applied as it existed at the time, or else it is an ex post facto law. That is all under US law of course. Who knows what German law provides. It does create some interesting issues, though, as to works that were legally purchased by a private German citizen from Jews who were fleeing Hitler and selling at rock bottom prices. As for art stolen by the Nazis from Jews who were being sent to the camps, those should be returned, no issues.
