Whether Congress had constitutional authority to withdraw the Supreme Court’s appellate jurisdiction over McCardle’s pending habeas appeal.
Holding
Yes. Congress may make express exceptions to the Supreme Court’s appellate jurisdiction under Article III.
Reasoning
The Court began with jurisdiction because it could not properly decide any other question unless it retained authority to hear the appeal. Although the Constitution confers appellate jurisdiction on the Supreme Court, it does so “with such exceptions and under such regulations as Congress shall make.”
Prior decisions had established that Congress’s statutes defining the Court’s appellate jurisdiction operate as exercises of its constitutional power to make exceptions to that jurisdiction. Thus, while the Constitution is the ultimate source of appellate power, Congress may limit the categories of appeals the Court may hear.
Here, Congress did not merely leave jurisdiction unmentioned or imply a limitation by granting jurisdiction elsewhere. The 1868 Act expressly repealed the provision of the 1867 Act that authorized appeals in habeas cases such as McCardle’s. The Court regarded that repeal as an unmistakable, affirmative exception to its appellate jurisdiction.
The Court declined to examine Congress’s motives for withdrawing jurisdiction. Its task was limited to deciding whether Congress possessed the constitutional power to make the exception, and the Court concluded that the Constitution expressly gave Congress that power.
