A federal appeals court panel Wednesday weighed whether the district court overseeing the NFL concussion class action settlement may supervise litigation funders in the case.

The U.S. Court of Appeals for the Third Circuit eyed the jurisdiction of trial judges who oversee class action settlement proceeds when claimants have entered into lending agreements. The funders said those contracts are independent of the settlement, and any disputes are subject to arbitration. But lead class counsel said the arrangements are subject to the court’s judgment as to how best to implement the settlement.
