At any time for cause shown, the court may excuse a grand juror either temporarily or permanently and may swear another grand juror from a current jury panel in place of the one excused. The discharge of any such grand juror shall in no way or manner affect any indictment found by the grand jury as it was composed either before or after such discharge. If it is impossible to fill the vacancy on the grand jury from a current jury panel, the chief circuit judge may summon, using the procedure in Section 10(8) of these Rules, such number of prospective jurors as deemed necessary for the purpose.
