According to the United States Courts, it is legally required to respond to a jury notice, and penalties apply for noncompliance. Jurors must be a citizen of the United States, be over 18 years old, and be able to read, write and understand English to a proficient degree.
Potential jurors are randomly selected from a variety of sources, such as voter registration lists, licensed drivers, and lists of identification cardholders, reports The State Bar of California. Selected individuals then undertake a questionnaire to determine whether they meet the legal requirements for jury service, explains United State Courts. Completed questionnaires must be returned to the clerk's office, where they are screened for eligibility.
The Jury Act lists three groups of individuals who are exempt from jury service, according to United State Courts. This includes members of the armed forces on active duty, members of professional fire and police departments, and public officers of federal, state or local governments, who are actively engaged in the performance of public duties.
