The Supreme Court will hear its final arguments of 2020, starting with a pair of cases seeking to reclaim Nazi-looted art.

In those cases—Germany v. Philipp and Hungary v. Simon—the justices will consider whether Holocaust survivors and their families can sue former Axis countries in the U.S. or whether they must press their claims oversees.

It's déjà vu for the remainder of the week, as the justices will consider issues—and in one instance, a case—that they've recently tackled in previous terms.

In Facebook v. Duguid, the court will once again consider what counts as a prohibited "robocall" under the Telephone Consumer Protection Act.

The arbitration case Henry Schein Inc. v. Archer and White Sales Inc. comes back to the court for a second time. This time the justices will consider when an arbitrator—not a court—gets to decide whether claims should go to arbitration or should they go to the judiciary in the first instance.

Finally, the court considers another separation of powers challenge to a federal agency—this time the Federal Housing Finance Agency—in Collins v. Mnuchin.
