Okla. Stat. tit. 12, § 12-572: Causes for challenging jurors

If there shall be impaneled, for the trial of any cause, any

petit juror, who shall have been convicted of any crime which by law

renders him disqualified to serve on a jury; or who has been

arbitrator on either side, relating to the same controversy; or who

has an interest in the cause; or who has an action pending between

him and either party; or who has formerly been a juror in the same

cause; or who is the employer, employee, counselor, agent, steward

or attorney of either party; or who is subpoenaed as a witness; or

who is of kin to either party; or any person who shall have served

once already on a jury, as a talesman on the trial of any cause, in

the same court during the term, he may be challenged for such

causes; in either of which cases the same shall be considered as a

principal challenge, and the validity thereof be tried by the court;

and any petit juror who shall be returned upon the trial of any of

the causes hereinbefore specified, against whom no principal cause

of challenge can be alleged, may, nevertheless, be challenged on

suspicion of prejudice against, or partiality for either party, or

for want of competent knowledge of the English language, or any

other cause that may render him, at the time, an unsuitable juror;

but a resident and taxpayer of the state or any municipality therein

shall not be thereby disqualified in actions in which such

municipality is a party. The validity of all challenges shall be

determined by the court.
