Mississippi Code Title 9. Courts § 9-4-3

(1) The Court of Appeals shall have the power to determine or otherwise dispose of any appeal or other proceeding assigned to it by the Supreme Court.

The jurisdiction of the Court of Appeals is limited to those matters which have been assigned to it by the Supreme Court.

The Supreme Court shall prescribe rules for the assignment of matters to the Court of Appeals. These rules may provide for the selective assignment of individual cases and may provide for the assignment of cases according to subject matter or other general criteria. However, the Supreme Court shall retain appeals in cases imposing the death penalty, or cases involving utility rates, annexations, bond issues, election contests, or a statute held unconstitutional by the lower court.

(2) Decisions of the Court of Appeals are final and are not subject to review by the Supreme Court, except by writ of certiorari. The Supreme Court may grant certiorari review only by the affirmative vote of four (4) of its members. At any time before final decision by the Court of Appeals, the Supreme Court may, by order, transfer to the Supreme Court any case pending before the Court of Appeals.

(3) The Court of Appeals shall have jurisdiction to issue writs of habeas corpus, mandamus, quo warranto, certiorari, prohibition or any other process when this may be necessary in any case assigned to it by the Supreme Court.

(4) The Court of Appeals shall issue a decision in every case heard before the Court of Appeals within two hundred seventy (270) days after the final briefs have been filed with the court.

(5) The Supreme Court shall issue a decision in every case within its original jurisdiction, including all direct and post-conviction collateral relief appeals or applications in cases imposing the death penalty, within two hundred seventy (270) days after the final briefs have been filed with the court. The Supreme Court shall issue a decision in every case received on certiorari from the Court of Appeals within one hundred eighty (180) days after the final briefs have been filed with the court.
