what does impanel grand jury means?
The grand jury plays an important role in the criminal process, but not one that involves a finding of guilt or punishment of a party. Instead, a prosecutor will work with a grand jury to decide whether to bring criminal charges or an indictment against a potential defendant -- usually reserved for serious felonies. Grand jury members may be called for jury duty for months at a time, but need only appear in court for a few days out of every month.
