Okla. Stat. tit. 22, § 22-329: Discharge of grand juror

A member of the grand jury may for ill health of himself or

immediate family, or other cause rendering him unable to serve, be

discharged before the term is ended or the labor of the grand jury

completed; or, if the judge becomes satisfied that any grand juror

is willfully refusing to discharge his duty, the court may order his

discharge. In the event of the discharge or death of a grand juror,

an alternate grand juror shall be appointed to fill the vacancy by

the court. The appointment shall be made in the same order in which

the alternate grand jurors were selected. If the number of grand

jurors and alternates becomes so depleted as to prevent the grand

jury from functioning, as many names as the court may order shall be

drawn from the jury box in the same manner the original grand jurors

and alternates were drawn, and from the names so drawn there shall

be summoned as many grand jurors and alternates as can be found and

are able to attend as necessary, and if found they shall be summoned

in the order in which their names were drawn from the box. If the

number be not thus obtained there shall be another drawing in the

same manner. When a sufficient number so drawn appears to fill the

panel, the grand jury shall in open court be reimpaneled, but

subject to challenge and be charged and sworn in the same manner as

when the grand jury was originally impaneled.
