Constitution of the State of Georgia Art. VI, § 1, ¶ I

The judicial power of the state shall be vested exclusively in the following classes of courts: magistrate courts, probate courts, juvenile courts, state courts, superior courts, state-wide business court, Court of Appeals, and Supreme Court. Nothing in this paragraph shall preclude a superior court from creating a business court division for its circuit in a manner provided by law. Magistrate courts, probate courts, juvenile courts, and state courts shall be courts of limited jurisdiction. In addition, the General Assembly may establish or authorize the establishment of municipal courts and may authorize administrative agencies to exercise quasi-judicial powers. Municipal courts shall have jurisdiction over ordinance violations and such other jurisdiction as provided by law. Except as provided in this paragraph and in Section X, municipal courts, county recorder's courts and civil courts in existence on June 30, 1983, and administrative agencies shall not be subject to the provisions of this article. The General Assembly shall have the authority to confer “by law” jurisdiction upon municipal courts to try state offenses.
