Section 4. District courts of appeal.

(a) ORGANIZATION.—There shall be a district court of appeal serving each appellate district. Each district court of appeal shall consist of at least three judges. Three judges shall consider each case and the concurrence of two shall be necessary to a decision.
(b) JURISDICTION.—
(1) District courts of appeal shall have jurisdiction to hear appeals, that may be taken as a matter of right, from final judgments or orders of trial courts, including those entered on review of administrative action, not directly appealable to the supreme court or a circuit court. They may review interlocutory orders in such cases to the extent provided by rules adopted by the supreme court.
(2) District courts of appeal shall have the power of direct review of administrative action, as prescribed by general law.
(3) A district court of appeal or any judge thereof may issue writs of habeas corpus returnable before the court or any judge thereof or before any circuit judge within the territorial jurisdiction of the court. A district court of appeal may issue writs of mandamus, certiorari, prohibition, quo warranto, and other writs necessary to the complete exercise of its jurisdiction. To the extent necessary to dispose of all issues in a cause properly before it, a district court of appeal may exercise any of the appellate jurisdiction of the circuit courts.
(c) CLERKS AND MARSHALS.—Each district court of appeal shall appoint a clerk and a marshal who shall hold office during the pleasure of the court and perform such duties as the court directs. Their compensation shall be fixed by general law. The marshal shall have the power to execute the process of the court throughout the territorial jurisdiction of the court, and in any county may deputize the sheriff or a deputy sheriff for such purpose.
