What is the Purpose of a Grand Jury?

Grand juries are part of our Constitution. The purpose of the grand jury is to determine whether or not there is probable cause to believe that any federal felony has been committed.

Keep in mind just because you received a grand jury subpoena does not mean you are a potential defendant or the target of a criminal investigation. Therefore, you should contact an attorney to determine precisely why you received the subpoena.
