§ 1004 Reprieve and suspension of execution - Authority of officers.

Only the Governor has the power to delay or pause a death sentence in Oklahoma. No judge, court, or other official can step in and stop the execution once it's been ordered.

There's one exception to this. The prison warden holding the inmate can delay the execution, but only in specific situations spelled out in other related rules. This might happen, for example, if there's a medical or procedural reason that comes up right before the execution is set to happen.

If the person sentenced to death files an appeal, that changes things too. An appeal can put the execution on hold through the normal court process, separate from the Governor's power to grant a reprieve.
