(a)Examination of jurors. – The court may permit the parties or their attorneys to conduct the examination of prospective jurors or may itself conduct the examination. In the latter event, the court shall permit the parties or their attorneys to supplement the examination by such further inquiry as it deems proper or shall itself submit to the prospective jurors such additional questions of the parties or their attorneys as it deems proper. (b)Jury selection. – Unless the court directs that a jury shall consist of a greater number, a jury shall consist of six persons. The plaintiff and the defendant shall each have two preemptory challenges which shall be exercised one at a time, alternately, beginning with the plaintiff. Several defendants or several plaintiffs may be considered as a single party for the purpose of exercising challenges, may allow additional peremptory challenges and permit them to be exercised separately or jointly. (c)Alternate jurors. – The court may direct that not more than six jurors in addition to the regular jury be called and impanelled to sit as alternate jurors. Alternate jurors in the order in which they are called shall replace jurors who become or are found to be unable or disqualified to perform their duties. Alternate jurors shall be drawn in the same manner, shall have the same qualifications, shall be subject to the same examination and challenges, shall take the same oath, and shall have the same functions, powers, facilities, and privileges as the regular jurors. Each side is entitled to 1 additional peremptory challenge if 1 to 3 alternate jurors are to be impanelled and 2 additional peremptory challenges if 4 to 6 alternate jurors are to be impanelled. The additional peremptory challenges may be used against an alternate juror only, and the other peremptory challenges allowed by law shall not be used against an alternate juror. (d)Excuse. – The court may for good cause excuse a juror from service during trial or deliberation.
