When from challenge or from any other cause there are not a sufficient number of persons in attendance to complete the empaneling of grand jurors, the presiding judge shall order the clerk to choose at random from the names of persons summoned as trial jurors a sufficient number of prospective grand jurors necessary to complete the grand jury. Nothing in this Code section shall be construed as barring the court from taking any action against a person who has been summoned to appear as a juror as provided in Code Section 15-12-10.
