Selection and Preparation of Grand Jurors

(a) Summons. Grand jurors shall be summoned and impaneled as provided by law. (b) Service of Grand Jury. (1) Generally. Grand juries may be impaneled and serve both in term time and vacation. (2) Number of Grand Jurors. The grand jury shall consist of at least fifteen (15) persons, but not more than twenty-five (25) persons, the exact number to be within the discretion of the judge impaneling the jury. If during the service of a grand jury the number of grand jurors able to serve on the grand jury shall become less than fifteen (15), then the circuit judge may have additional grand jurors summoned, impaneled, and charged in the same manner as the original grand jurors. (3) Convening the Grand Jury. Upon impanelment, a grand jury may be convened and reconvened by order of the court. The grand jury will continue to serve until the next grand jury is impaneled and it may return indictments to court in term time or vacation notwithstanding intervening terms of court between the time the grand jury is impaneled and the time an indictment is returned. (c) Impanelment of Grand Jury. Before swearing grand jurors as such, the grand jurors shall be examined by the court, on oath, touching their qualifications. After the grand jurors have been sworn and impaneled, no objection shall be raised, by plea or otherwise, to the grand jury, but the 70 impaneling of the grand jury shall be conclusive evidence of its competency and qualifications. However, any party interested may challenge or except to the array for fraud.

State, 132 So. 3d 568, 572 (Miss. 2014).
