Answer to Question 1
Subpoenas
Two types of subpoenas are available to grand juries: (1) a subpoena ad testificandum and (2) a subpoena duces tecum. The former compels a witness to appear before the grand jury, and the latter compels the production of tangible evidence. The power of the grand jury to utilize both of these mechanisms is virtually unrestricted.
Grants of Immunity
Although witnesses appearing before a grand jury enjoy the Fifth Amendment privilege against self-incrimination, the grand jury can avoid this limitation by extending grants of immunity to witnesses in exchange for their testimony. A grant of transactional immunity prohibits future prosecution on the acts for which the witness testifies.
Findings of Contempt
When someone is subpoenaed to appear before the grand jury but does not show up, the jury's contempt power can be utilized to compel their appearance. That is, the grand jury can impose civil and criminal sanctions on the individual for failing to appear.
