Juror Selection Process

Legal Obligation

The United States Constitution and the Arizona State Constitution guarantee the right to trial by jury. Failure to attend as directed may subject you to penalties provided by law; A.R.S. § 21-223. All Maricopa County residents are obligated by state law to serve as a juror unless they:

  • Are NOT a United States citizen;
  • Are UNDER 18 years of age;
  • Have been convicted of a felony and their civil rights have NOT been restored.

The law automatically disqualifies non-citizens, convicted felons whose civil rights have not been restored, and people under 18 years of age from jury service.

Taking time off from work for jury service

State law prohibits an employer from discharging or discriminating against an employee for taking time to serve as a juror if the employee gives reasonable notice prior to serving.

Random Juror Selection Process

The list of names that is used to call people for jury service is created by combining the County's voter registration list and Arizona Department of Transportation records. Names are randomly selected from that master list by a computer program.

A computer program randomly selects names from the master jury file to summons potential jurors. Since that process is random, some people may be selected more than others.

The Jury Office adheres to the random selection process set out in the law. Because it is random, some people who are willing to serve may never be asked, and others who are not willing to be served may be asked frequently.

State law requires that Superior Court jurors be selected randomly. Although everyone would like to serve at a convenient court location, state law requires jurors to be randomly selected from the countywide population. Requests to be transferred to another court cannot be granted. You must appear at the court to which you were summonsed.

Previously Served and Summoned Again

If you appeared for jury service but were not chosen for a trial, you are exempt from serving for 18 months from the date of service.

If you served on a jury panel for a trial or were part of a jury selection that took longer than two days, you are exempt from serving for two years from the last day of service.

If you served on a grand jury panel (state or county) and appeared for more than two sessions, you are exempt from serving for four years from the last day of service. This does not apply to alternate grand jurors.

If you have received a summons within the periods listed above, please contact the jury office for assistance.

Permanent removal from Jury Master List

Under certain circumstances, such as permanent mental or physical disability, jury staff can permanently remove a name from its records. Please explain your situation in writing and return it to the Jury Office. Your request will be evaluated and you will be notified by mail of the decision.  You may be required to provide additional documentation for evaluation of your request.

Since April 13, 2005, people who receive a jury summons to an Arizona court who are at least 75 years of age may be excused upon written request. If you are eligible for this, and you wish to be excused, please call the Jury Office at 602-506-5879.
