Every jurisdiction employs different procedures and rules when it comes to granting exemptions for jury duty, explains USCourts.gov. In most state courts, including Maryland Courts and the California State Bar, exemption is possible if the juror falls under certain circumstances that include mental disability, undue hardship and extreme inconvenience.
Many courts grant exemptions from jury duty service if the person is over the age of 70 or has a law- or criminal law-related job that may raise bias during the hearing in court, states USCourts.gov. While the Jury Act allows active duty officers to pass jury duty, most states do not grant that specific exemption. Some states, such as Tennessee, excuse those who have served their jury duties within 24 months of the current summons.
