Federal courts are courts of limited jurisdiction. They only have the jurisdiction specifically granted to them by statute and the Constitution. There is no statute giving a district court the jurisdiction to hear Trump's lawsuit.
Trump's lawsuit relied on a series of lower-court cases recognizing an "exceptional," "anomalous" form of equitable jurisdiction to order the government to return property seized under a search warrant before any indictment. The 11st Circuit held that the factors courts have held necessary to support such jurisdiction were absent here.
Thank you. What are the factors necessary to support such jurisdiction?
