(a) Impaneling Juries. In criminal cases the parties shall pass upon and accept the jury in
panels of four, commencing with the State, unless the court, in its discretion, directs otherwise, and alternate jurors shall be passed upon separately.
(b) Names and Addresses of Prospective Jurors. Upon request, the parties shall be furnished with a list of prospective jurors with their addresses, if known.
(c) Challenging Prospective Jurors for Cause. Each party may challenge jurors for cause. If a prospective juror has a physical impairment, the court shall consider such prospective juror’s ability to perceive and appreciate the evidence when considering a challenge for cause.
(d) Peremptory Challenges. A defendant tried alone shall be allowed seven peremptory challenges in a case in which the punishment may be imprisonment in the penitentiary, and five in all other cases; except that, in a single trial of more than one defendant, each defendant shall be allowed five peremptory challenges in a case in which the punishment may be imprisonment in the penitentiary, and three in all other cases. If several charges against a defendant or defendants are consolidated for trial, each defendant shall be allowed peremptory challenges upon one charge only, which single charge shall be the charge against that defendant authorizing the greatest maximum penalty. The State shall be allowed the same number of peremptory challenges as all of the defendants.
(e) Selection of Alternate Jurors. After the jury is impaneled and sworn the court may direct the selection of alternate jurors, who shall take the same oath as the regular jurors. Each party shall have one additional peremptory challenge for each alternate juror. If before the final submission of a cause a member of the jury dies or is discharged he shall be replaced by an alternate juror in the order of election.

Plain-English Summary

Rule 434 handles the procedural side of assembling a criminal jury. Jurors are passed on and accepted in panels of four, with the state going first unless the court directs otherwise, and alternates are handled as a separate group. On request, the parties get a list of prospective jurors and their addresses if known, and either side may challenge jurors for cause, with the court weighing a prospective juror's physical impairment against that juror's ability to perceive and evaluate the evidence.

Peremptory challenges vary by case. A defendant tried alone gets seven if the offense could carry a penitentiary sentence, five otherwise. When multiple defendants are tried together, each gets fewer, five or three, respectively, and if several charges against a defendant have been consolidated, the challenges apply only to the single charge carrying the greatest maximum penalty. The state gets as many peremptory challenges as all the defendants combined.

After the regular jury is sworn, the court may direct that alternate jurors be selected, giving each side one additional peremptory challenge per alternate. If a juror dies or is discharged before the case is finally submitted, an alternate steps in, in the order the alternates were chosen.

Frequently Asked Questions

How many peremptory challenges does a defendant tried alone get?
Seven if the offense could carry a penitentiary sentence, five in all other cases.

Yes. Each defendant gets five if the offense could carry a penitentiary sentence, or three otherwise, and the state gets as many total challenges as all defendants combined.
Can the parties get a list of prospective jurors' addresses?
Yes, on request, if the addresses are known.
How are alternate jurors chosen and used?
The court may direct their selection after the regular jury is sworn, with each side getting one extra peremptory challenge per alternate. An alternate replaces a juror who dies or is discharged, in the order the alternates were picked.
