(1) Every member of the grand jury shall keep secret whatever he, she, or any other grand juror has said, and how he, she, or any other grand juror has voted, except for disclosure of indictments, if any, as provided in RCW 10.27.150.

     (2) No grand juror shall be permitted to state or testify in any court how he, she, or any other grand juror voted on any question before them or what opinion was expressed by himself, herself, or any other grand juror regarding such question.

     (3) No grand juror, public or private attorney, city attorney or corporation counsel, reporter, interpreter or public servant who held a witness in custody before a grand jury or special inquiry judge, or witness, principal or other person shall disclose the testimony of a witness examined before the grand jury or special inquiry judge or other evidence received by it, except when required by the court to disclose the testimony of the witness examined before the grand jury or special inquiry judge for the purpose of ascertaining whether it is consistent with that of the witness given before the court, or to disclose his or her testimony given before the grand jury or special inquiry judge by any person upon a charge against such person for perjury in giving his or her testimony or upon trial therefor, or when permitted by the court in furtherance of justice.

     (4) The public attorney shall have access to all grand jury and special inquiry judge evidence and may introduce such evidence before any other grand jury or any trial in which the same may be relevant.

     (5) The court upon a showing of good cause may make any or all grand jury or special inquiry judge evidence available to any other public attorney, prosecuting attorney, city attorney or corporation counsel upon proper application and with the concurrence of the public attorney attending such grand jury. Any witness' testimony, given before a grand jury or a special inquiry judge and relevant to any subsequent proceeding against the witness, shall be made available to the witness upon proper application to the court. The court may also, upon proper application and upon a showing of good cause, make available to a defendant in a subsequent criminal proceeding other testimony or evidence:

     (a) When given or presented before a special inquiry judge, if doing so is in the furtherance of justice; or

     (b) When given or presented before a grand jury, if the court finds that doing so is necessary to prevent an injustice and that there is no reason to believe that doing so would endanger the life or safety of any witness or his or her family. The cost of any such transcript made available shall be borne by the applicant.
