GRAND JURY
grand jury.A body of (often 23) people who are chosen to sit permanently for at least a month
— and sometimes a year — and who, in ex parte proceedings, decide whether to issue indictments.
See Fed. R. Crim. P. 6. • If the grand jury decides that evidence is strong enough to hold a suspect
for trial, it returns a bill of indictment (a true bill) charging the suspect with a specific crime. —
Also termed accusing jury; presenting jury; jury of indictment. Cf. petit jury under JURY. [Cases:
Grand Jury 1.]
“The grand jury serves — or may serve — two distinct functions. One is a screening function;
the grand jury evaluates evidence supporting possible charges and returns an indictment only in
those cases in which the evidence amounts to at least probable cause. The other is an
investigatorial function; the grand jury sometimes develops information that is of value in
determining whether grounds for a charge exist and — perhaps incidentally — in proving that
charge at the defendant’s later criminal trial.” Frank W. Miller et al., Cases and Materials on
Criminal Justice Administration 546 (3d ed. 1986).
