 Congress rejected both proposals for a national court of appeals, but the studies drew attention to the problems associated with the lack of uniform rulings in specialized areas of jurisdiction.A proposal drafted by the Department of Justice led President Jimmy Carter to request in 1979 that Congress establish a court of appeals for a Federal Circuit, to be on the same jurisdictional level as the other U.S. courts of appeals.The proposed court would combine the functions of the Court of Customs and Patent Appeals with those of the U.S. Court of Claims, and the president also urged Congress to consider vesting the proposed court with the jurisdiction to promote uniformity and predictability in federal tax cases.
