Okla. Stat. tit. 22, § 639
When the panel is formed from persons whose names are not drawn as jurors, a challenge may be taken to the panel on account of any bias of the officer who summoned them, which would be good ground of challenge to a juror. Such challenge must be made in the same form, and determined in the same manner as if made to a juror.
