Ohio Const. art. IV, § 3

(A) The state shall be divided by law into compact appellate districts in each of which there shall be a court of appeals consisting of three judges. Laws may be passed increasing the number of judges in any district wherein the volume of business may require such additional judge or judges. In districts having additional judges, three judges shall participate in the hearing and disposition of each case. The court shall hold sessions in each county of the district as the necessity arises. The county commissioners of each county shall provide a proper and convenient place for the court of appeals to hold court.

(B)(1) The courts of appeals shall have original jurisdiction in the following:

(a) Quo warranto;

(b) Mandamus;

(c) Habeas corpus;

(d) Prohibition;

(e) Procedendo;

(f) In any cause on review as may be necessary to its complete determination.

(2) Courts of appeals shall have such jurisdiction as may be provided by law to review and affirm, modify, or reverse judgments or final orders of the courts of record inferior to the court of appeals within the district, except that courts of appeals shall not have jurisdiction to review on direct appeal a judgment that imposes a sentence of death. Courts of appeals shall have such appellate jurisdiction as may be provided by law to review and affirm, modify, or reverse final orders or actions of administrative officers or agencies.

(3) A majority of the judges hearing the cause shall be necessary to render a judgment. Judgments of the courts of appeals are final except as provided in section 2(B)(2) of this article. No judgment resulting from a trial by jury shall be reversed on the weight of the evidence except by the concurrence of all three judges hearing the cause.

(4) Whenever the judges of a court of appeals find that a judgment upon which they have agreed is in conflict with a judgment pronounced upon the same question by any other court of appeals of the state, the judges shall certify the record of the case to the supreme court for review and final determination.

(C) Laws may be passed providing for the reporting of cases in the courts of appeals.
