(a) The county boards of the respective counties, the jury commissioners for those counties which have been appointed under the Jury Commission Act, or a jury administrator shall submit questionnaires to prospective jurors to inquire as to their qualifications for jury service and as to the hardship that jury service would pose to the prospective jurors. Upon prior approval by the chief judge of the judicial circuits in which a county board, jury administrator, or jury commissioners are situated, the county board, jury administrator, or jury commissioners shall excuse a prospective juror from jury service if the prospective juror shows that such service would impose an undue hardship on account of the nature of the prospective juror’s occupation, business affairs, physical health, family situation, active duty in the Illinois National Guard or Illinois Naval Militia, or other personal affairs, and cause his or her name to be returned to the jury list or general jury list.
     (b) When an undue hardship caused by a family situation is due to the prospective juror being the primary care giver of a person with a mental or physical disability, a person with a medically diagnosed behavior problem, or a child under age 12, then the county board, jury commissioners or jury administrator shall excuse such a prospective juror, if it finds that no reasonable alternative care is feasible which would not impose an undue hardship on the prospective juror or the person for whom the prospective juror is providing care, or both.
