Okla. Stat. tit. 22, § 22-896: Discharge after agreement on verdict or showing of

inability to agree.

Except as provided in the last section, the jury cannot be

discharged after the cause is submitted to them until they have

agreed upon their verdict, and rendered it in open court, unless by

the consent of both parties entered upon the minutes, or unless at

the expiration of such time as the court deems proper, it

satisfactorily appear that there is no reasonable probability that

the jury can agree.
