Okla. Stat. tit. 12 § 952 : — Civil ProcedureAppeal and Error — Jurisdiction of Supreme Court

(a) The Supreme Court may reverse, vacate or modify judgments of the district court for errors appearing on the record, and in the reversal of such judgment may reverse, vacate or modify any intermediate order involving the merits of the action, or any portion thereof.

(b) The Supreme Court may reverse, vacate or modify any of the following orders of the district court, or a judge thereof:

1. A final order;

2. An order that discharges, vacates or modifies or refuses to vacate or modify a provisional remedy which affects the substantial rights of a party; or grants, refuses, vacates, modifies or refuses to vacate or modify an injunction; grants or refuses a new trial; or vacates or refuses to vacate a final judgment;

3. Any other order, which affects a substantial part of the merits of the controversy when the trial judge certifies that an immediate appeal may materially advance the ultimate termination of the litigation; provided, however, that the Supreme Court, in its discretion, may refuse to hear the appeal. If the Supreme Court assumes jurisdiction of the appeal, it shall indicate in its order whether the action in the trial court shall be stayed or shall continue.

The failure of a party to appeal from an order that is appealable under either subdivision 2 or 3 of subsection (b) of this section shall not preclude him from asserting error in the order after the judgment or final order is rendered.
