Grand Juries
(a) County grand jury. —
(1) Summoning Grand Juries. — A county grand jury shall be summoned
only when ordered by a district judge.
(2) Manner of Summoning. — A grand jury shall be drawn, summoned
and impaneled in the same manner as trial juries in civil actions.
(3) Term; Discharge and Excuse. — A grand jury shall serve until
discharged by the court, but no grand jury may serve more than 12 months
unless the court extends the service of the grand jury. Extensions shall be for
periods of six months or less, for good cause only, and upon a determination
that such extension is in the public interest. At any time for cause shown, the
court may excuse a juror either temporarily or permanently, and in the latter
event the court may impanel another person in place of the juror excused.
(4) Composition; Qualification; Alternates.
(A) Number and Qualifications. — A grand jury shall consist of 12
persons who shall possess the qualifications of trial jurors.
(B) Quorum. — Not less than nine jurors may act as the grand jury.
(C) Alternate Jurors. — The court may direct that alternate jurors may
be designated at the time a grand jury is selected. Alternate jurors in the
order in which they were designated may thereafter be impaneled as
provided in subdivision (a)(3). Alternate jurors shall be drawn in the same
manner and shall have the same qualifications as the regular jurors, and
if impaneled shall be subject to the same challenges, shall take the same
oath and shall have the same functions, powers, facilities and privileges as
the regular jurors.
(5) Objections to Grand Jury and to Grand Jurors.
(A) Challenges. — The attorney for the state may challenge the array of
jurors on the ground that the grand jury was not selected, drawn or
summoned in accordance with law, and may challenge an individual juror
on the ground that the juror is not legally qualified. Challenges shall be
made before the administration of the oath to the jurors and shall be tried
by the court.
(B) Motion to Dismiss. — A motion to dismiss an indictment may be
based on objections to the array or on the lack of legal qualification of an
individual juror, if not previously determined upon challenge. An indictment shall not be dismissed on the ground that one or more members of
the grand jury were not legally qualified if it appears from the record kept
pursuant to this rule that nine or more jurors, after deducting the number
not legally qualified, concurred in finding the indictment.
(6) Indictment.
(A) Finding to Indict. — No indictment shall be found unless the finding
is concurred in by at least nine members of the grand jury.
(B) A True Bill. — If an indictment is found as provided by this
subdivision, the presiding juror of the grand jury shall endorse upon the
indictment the words “A True Bill” and shall sign the indictment.
(C) Sealed Indictments. — The district judge to whom an indictment is
returned may direct that the indictment be kept secret until the defendant
is in custody or has been released pending trial. If so directed the clerk
shall seal the indictment and no person shall disclose the return of the
indictment except as necessary for the issuance and execution of a warrant
or summons.
(7) Presiding Juror; Oath of Jurors; Charge.
(A) Presiding Juror. — The district judge shall appoint one of the jurors
to be presiding juror and another to be deputy presiding juror. The
presiding juror shall have power to administer oaths and affirmations and
shall sign all indictments. The presiding juror or another juror designated
by the presiding juror shall keep a record of the number of jurors
concurring in the finding of every indictment and shall file the record with
the clerk of the court, but the record shall not be made public except on
order of the court. During the absence of the presiding juror, the deputy
presiding juror shall act as presiding juror.
(B) Oath. — Before entering upon their duties, jurors shall swear or
affirm that each of them shall:
(i) Diligently inquire into all matters coming before them;
(ii) Find and present indictments truthfully and without malice, fear
of reprisal or hope of reward; and
(iii) Keep secret matters occurring before the grand jury unless
disclosure is directed or permitted by the court.
(C) Charge. — After the grand jury is impaneled and sworn, the district
judge shall charge the jurors as to their duties, including their obligation
of secrecy, and give them any information the court deems proper
concerning any offenses known to the court and likely to come before the
grand jury.
(8) Powers. — The grand jury may:
(A) Inquire into any crimes committed or triable within the county and
present them to the court by indictment; or
(B) Investigate and report to the court concerning the condition of the
county jail and the treatment of prisoners.
(9) Appearance before Jury.
(A) Attorneys for State. — Attorneys for the state may appear before the
grand jury for the purpose of:
(i) Giving information relative to any matter under inquiry;
(ii) Giving requested advice upon any legal matter; and
(iii) Interrogating witnesses.
(B) Who May Be Present. — Attorneys for the state, the witness under
examination, interpreters when needed and, for the purpose of taking the
evidence, a stenographer or operator of a recording device may be present
while the grand jury is in session, but no person other than the jurors may
be present while the grand jury is deliberating or voting.
(10) Recording and Disclosure of Proceedings. — All proceedings, except
when the grand jury is deliberating or voting, shall be recorded stenographi-
cally or by an electronic recording device. An unintentional failure of any
recording to reproduce all or any portion of a proceeding shall not affect the
validity of the prosecution. The recording or reporter’s notes or any transcript prepared therefrom shall remain in the custody or control of the
attorney for the state unless otherwise ordered by the court in a particular
case.
(11) Process for Witnesses. — If requested by the grand jury or the
attorney for the state, the clerk of the court in which the jury is impaneled
shall issue subpoenas for the attendance of witnesses to testify before the
grand jury.
(12) Administration of Oath or Affirmation to Witnesses. — Before any
witness is examined by the grand jury, an oath or affirmation shall be
administered to the witness by the presiding juror.
(13) Refusal of Witness to Testify. — If a witness appearing before a grand
jury refuses, without just cause shown, to testify or provide other information, the attorney for the state may take the witness before the court for an
order directing the witness to show cause why the witness should not be held
in contempt. If after the hearing, the court finds that the refusal was without
just cause, and if the witness continues to refuse to testify or produce
evidence, the court may hold the witness in contempt subject to punishment
provided by statute or these rules. The witness has the right to be
represented by counsel at such hearing. Nothing in this rule shall be
construed to require or permit the court to compel testimony under a grant
of immunity unless such a procedure is expressly authorized by statute.
(14) Confidentiality.
(A) Disclosure by Attorney for State. — Disclosure of matters occurring
before the grand jury, other than its deliberations and the vote of any juror,
may be made to the attorney for the state for use in the performance of the
duties of the attorney for the state. The attorney for the state may disclose
so much of the grand jury’s proceeding to law enforcement agencies as the
attorney for the state deems essential to the public interest and effective
law enforcement.
(B) Disclosure by Others. — Except as provided in subparagraph (A), a
juror, attorney, interpreter, stenographer, operator of a recording device or
any typist who transcribes recorded testimony may disclose matters
occurring before the grand jury only when so directed by the court
preliminarily to, or in connection with a judicial proceeding, or when
permitted by the court at the request of the defendant upon a showing that
a particularized need exists for a motion to dismiss the indictment because
of matters occurring before the grand jury. No obligation of secrecy may be
imposed upon any person except in accordance with this rule. A knowing
violation of this provision may be punishable as contempt of court.
(C) Closed Hearing. — Subject to any right to an open hearing in
contempt proceedings, the court shall order a hearing on matters affecting
a grand jury proceeding to be closed to the extent necessary to prevent
disclosure of matters occurring before a grand jury.
(D) Sealed Records. — Records, orders and subpoenas relating to grand
jury proceedings shall be kept under seal to the extent and for such time
as is necessary to prevent disclosure of matters occurring before a grand
jury.
(15) Presentation and Filing of Indictment. — Indictments found by the
grand jury shall be presented by the presiding juror to the district judge in
open court in the presence of the grand jury and filed with the clerk.
(b) State grand jury. —
(1) Petition for Impaneling; Determination by District Judge. — If the
governor or the attorney general deems it to be in the public interest to
convene a grand jury which shall have jurisdiction extending beyond the
boundaries of any single county, the governor or attorney general may
petition a judge of any district court for an order in accordance with the
provisions of Rule 6(b). The district judge may, for good cause shown, order
the impaneling of a state grand jury which shall have statewide jurisdiction.
In making a determination as to the need for impaneling a state grand jury,
the judge shall require a showing that the matter cannot be effectively
handled by a county grand jury impaneled pursuant to subdivision (a).
(2) Powers and Duties; Applicable Law; Procedural Rules. — A state
grand jury shall have the same powers and duties and shall function in the
same manner as a county grand jury, except for the provisions of this
subdivision, and except that its jurisdiction shall extend throughout the
state. The procedural rules applicable to county grand juries shall apply to
state grand juries except when inconsistent with the provisions of this
subdivision.
(3) Selection and Term of Members. — The clerk of the district court in
each county of the state, upon receipt of an order of the district judge of the
court granting a petition to impanel a state grand jury, shall prepare a list
of 15 prospective state grand jurors drawn from existing jury lists of the
county. The list so prepared shall be immediately sent to the clerk of the
court granting the petition to impanel the state grand jury. The district judge
granting the order shall impanel the state grand jury from the lists compiled
by the clerk of court. The judge preparing the final list from which the grand
jurors will be chosen need not include the names of the jurors from every
county within the state having due regard for the expense and inconvenience
of travel. A state grand jury shall be composed of 12 persons, but not more
than one-half (½) of the members of the state grand jury shall be residents
of any one county. The members of the state grand jury shall be selected by
the court in the same manner as jurors of county grand juries and shall serve
for one year following selection unless discharged sooner by the district
judge.
(4) Summoning of Jurors. — Jurors shall be summoned and selected in
the same manner as jurors of county grand juries.
(5) Judicial Supervision. — Judicial supervision of the state grand jury
shall be maintained by the district judge who issued the order impaneling
the grand jury, and all indictments, reports and other formal returns of any
kind made by the grand jury shall be returned to that judge.
(6) Presentation of Evidence. — The presentation of the evidence shall be
made to the state grand jury by the attorney general or the attorney
general’s designee. In the event the office of the attorney general is under
investigation, the presentation of evidence shall be made to the state grand
jury by an attorney appointed by the Wyoming Supreme Court.
(7) Return of Indictment; Designation of Venue; Consolidation of Indictments. — Any indictment by the state grand jury shall be returned to the
district judge without any designation of venue. Thereupon, the judge shall,
by order, designate the county of venue for the purpose of the trial. The judge
may order the consolidation of an indictment returned by a county grand
jury with an indictment returned by a state grand jury and fix venue for the
trial.
(8) Investigative Powers; Secrecy of Proceedings.
(A) Report to Attorney General. — In addition to its powers of indictment, a statewide grand jury impaneled under this subdivision may, at the
request of the attorney general, cause an investigation to be made into the
extent of organized criminal activity within the state and return a report
to the attorney general.
(B) Disclosure by Attorney General and District Attorney. — Disclosure
of matters occurring before the grand jury, other than its deliberations and
the vote of any juror, may be made to the attorney general and to any
district attorney for use in the performance of their duties. Those officials
may disclose so much of the grand jury’s proceedings to law enforcement
agencies as they deem essential to the public interest and effective law
enforcement.
(C) Disclosure by Others. — Except as provided in subparagraph (B), a
juror, attorney, interpreter, stenographer, operator of a recording device or
any typist who transcribes recorded testimony may disclose matters
occurring before the grand jury only when so directed by the court
preliminarily to, or in connection with, a judicial proceeding, or when
permitted by the court at the request of the defendant upon a showing that
a particularized need exists for a motion to dismiss the indictment because
of matters occurring before the grand jury.
(D) Other Obligations of Secrecy. — No obligation of secrecy may be
imposed upon any person except in accordance with this rule. The court
may direct that an indictment shall be kept secret until the defendant is
in custody or has given bail, and in that event, the clerk shall seal the
indictment and no person shall disclose the finding of the indictment
except when necessary for the issuance and execution of a warrant or
summons. A knowing violation of this provision may be punishable as
contempt of court.
(9) Costs and Expenses. — The costs and expenses incurred in impaneling
a state grand jury and in the performance of its functions and duties shall be
paid by the state out of funds appropriated to the attorney general for that
purpose.
