Before swearing any grand juror as such, he shall be examined by the court, on oath, touching his qualification. After the grand jurors shall have been sworn and impaneled, no objection shall be raised, by plea or otherwise, to the grand jury, but the 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.
