How many jurors each side can reject without giving a reason

(a) In addition to the challenges of jurors allowed in section 635-28, the State and defendant in criminal cases shall be allowed peremptory challenges as provided by section 635-30. (b) In civil cases each party shall be allowed to challenge peremptorily three jurors, without assigning any reason therefor.

If additional peremptory challenges are allowed to the parties on one side, the opposing party or parties may be allowed additional peremptory challenges.
