O.C.G.A. § 23-4-34: Interlocutory decrees and orders.

At any stage in the progress of an action seeking equitable relief, if any portion of the same is ready for or requires a decree, the court may hear and determine such matters and pass such interlocutory decree or order as may advance the cause and expedite a final hearing. If no issue of fact is involved, the verdict of a jury shall be unnecessary.
