Witnesses
A Grand Jury is different from a jury at trial in several ways. For example, while a jury at trial consists of 12 jurors who must unanimously conclude beyond a reasonable doubt a defendant is guilty in order to convict, a Grand Jury consists of anywhere between 16 to 23 members merely voting on whether probable cause exists for the charges presented. Rather than requiring unanimity, a minimum of 12 grand jurors must agree such probable cause exists in order to “true bill” the charges to allow the charges to proceed to court. The defendant is not convicted of anything just because charges are “true billed.” On the other hand, the grand jury may instead vote to “no bill” charges. If charges are “no billed” on two separate occasions, a prosecution on those charges is barred.
Be Prepared
Review the case in your mind a day or two before your court date. It may help to picture the scene in your head so that you can recall it more accurately when you are on the witness stand.


Always Tell The Truth
It is normal to be nervous; the most important thing to remember is to always tell the truth. Even a so-called “minor fabrication” can completely discredit a witness and significantly weaken the entire case.
Look Your Best
A neat appearance and proper dress in court is very important. Dress neatly and conservatively, as if you were going to church. Shorts, tank tops and hats are not allowed in the courtroom. Do not eat, drink, or chew gum in the courtroom.


Be Prepared To Wait
You may want to bring something to read. The court process is unpredictable. Although the attorneys will try to accommodate your schedule, you will likely have to wait for some period of time before you testify.
Be On Your Best Behavior
Often times witnesses are judged by their behavior, both in and out of the courtroom.


Listen Carefully
Be sure that you understand the question thoroughly before you answer, and then answer only what is asked. If you do not know the answer, do not guess.
Avoid Jurors
Avoid jurors during recess. Under no circumstances should you approach a juror, even though it may be a matter wholly non-related to the case on trial.
