The U.S. Supreme Court heard two cases concerning whether American courts have a role in deciding whether Hungary and Germany must pay for property said to have been stolen from Jews before and during WWII, the New York Times said.

The Hungarian case, Republic of Hungary v. Simon, was brought by 14 Holocaust survivors, four of them United States citizens, who said their property was stolen by Hungary and its state-owned railway, which deported hundreds of thousands of Jews to Nazi death camps in the summer of 1944.

The German case, Federal Republic of Germany v. Philipp, concerns the Guelph Treasure, a trove of medieval religious art that was once owned by a consortium of Jewish art dealers in Frankfurt and that is now estimated to be worth $250 million.

A decision is expected in late winter or spring.
