Ex parte McCardle

Ex parte McCardle, 74 U.S. (7 Wall.) 506 (1869), is a United States Supreme Court decision that considered its jurisdiction to review decisions of lower courts under federal law.

Case history
During the Civil War Reconstruction, newspaper publisher William McCardle printed some "incendiary" articles, advocating opposition to the Reconstruction laws enacted by Congress. He was jailed by a military commander under the Military Reconstruction Act of 1867. McCardle invoked habeas corpus in the Circuit Court of the Southern District of Mississippi. The judge sent him back into custody, finding the military actions legal under Congress' law. He appealed to the Supreme Court under the Habeas Corpus Act of 1867, which granted appellate jurisdiction to review denial of habeas corpus petitions. After the case was argued but before an opinion was delivered, Congress suspended the Supreme Court's jurisdiction over the case, exercising the powers granted under Article III, section 2 of the Constitution.

Issues
Two issues were raised by this case: Whether the Supreme Court had jurisdiction to hear the case, and if so, whether McCardle's imprisonment violated his Fifth Amendment Due Process rights.

Holdings
Chief Justice Chase, writing for a unanimous court, validated congressional withdrawal of the Court's jurisdiction. The basis for this repeal was the exceptions clause of Article III, section 2. But Chase pointedly reminded his readers that the 1868 statute repealing jurisdiction "does not affect the jurisdiction which was previously exercised." Since the Court held it lacked jurisdiction to hear the case, the second question was not answered. Since Congress had withdrawn jurisdiction to hear the case, McCardle had no legal recourse to challenge his imprisonment in federal court.

Rationale
Durousseau v. United States, 10 U.S. 307 (1810)  held that Congress's affirmative description of certain judicial powers implied a negation of all other powers. Creating such legislation was legitimate under the authority granted them by the United States Constitution. By repealing the act that granted the Supreme Court authority to hear the case, Congress made a clear statement that they were using this Constitutional authority to remove the Supreme Court's jurisdiction. The court had no choice but to dismiss the case.
