Served the same jury duty, hoping I don't get picked again. (But knowing my luck...)
Anyway here's how it goes
You are on call basically. You must call in every day for the next 5 days. If they do not need you, they will say "Your group was not called in, please call again tommorow"
IF YOU ARE LUCKY, you don't even have to go to the courthouse. My father, brother, and girlfriend all got out this way, but lucky me, I had to go because my number was called.
Anyway if you are called you must go to the courthouse by the time they stated. Can be anywhere from 8:00AM to 10:00AM. You must be there for roll call/sign in or you are considered missing.
You sit in the room and wait for the entire day. If the case is dismissed, you leave and ARE DONE. No more jury duty for another 18 months.
If the case is not dismissed, they will randomly call names into the court room. If you are not called by the end of the day, you ARE DONE. No more jury duty for another 18 months.
If you are called they read you what you are suppose to do and the lawyers cross examine you. You are now in unlucky zone because you now have to reshow up to court the following day.
When you show up to court the next day for the case, you will go through a phase where the lawyers may dismiss you if they find any bias in you. (Now is a good time to pretend you have a BIAS since it will get you free) If you are dismissed at this phase, you ARE DONE. No more jury duty for 18 months.
If you're Joe A Citizen and can't tell a lie, they keep you. You must now serve on the case until it is done. This can be anywhere from 1 day to 3 months. Typically you will not run into a criminal case, but you never know.
Good luck!
