The U.S. Constitution guarantees the right to a trial by jury.  The jury must represent a cross-section of the community in order to prevent discrimination.  For this reason, citizens will only be excused from serving for a few reasons.  Most jurors do not qualify for a statutory exemption from jury duty.  However, if you believe you have an unusually difficult personal or business situation, you may provide that excuse to the court in writing.  The court will then determine whether or not you meet the statutory requirements allowing you to be excused.
