Regular (Petit) Jury Duty: These are the types of juries you generally see on television and in movies. Petit jurors serve for a two-week term and might be required to come to the courthouse for one (or more) days during those 2 weeks. If you receive a Petit Summons, you will need to check the jury schedule for both of your 2 weeks of service. Most Petit jurors only serve one day of the 2 weeks, but it is possible that you will have to report on more than 1 day.
Grand Jury: Unlike Petit jurors, Grand Jurors never need to check the Jury Schedule. Potential Grand Jurors will report for a 1-hour orientation where 24 people will be selected to serve. Those who are not selected to serve will be excused at the end of Orientation and won’t need to come back to the courthouse.
Grand Juries are very different from Petit juries. Grand Jurors listen to information about a variety of different cases brought by the District Attorney. Grand Jurors listen to evidence and decide if that evidence is strong enough to charge someone with a crime. Grand Jurors don’t decide the outcome of the cases they hear, but they make decisions about which cases should be tried and which should not. Selected Grand Jurors serve 1 day a week (either Wednesday or Thursday) for 8 or 9 weeks.
Special Trial: A summons for a “Special Trial” is like a Petit Summons, except the summons is for just one case. Anyone who isn’t selected to serve on that one trial will be excused at the end of juror selection. Special trials usually have a special orientation to fill out a questionnaire and then return at a later date for jury selection.
