Sec. 115-16. Witness disqualification. No person shall be disqualified as a witness in a criminal case or proceeding by reason of his or her interest in the event of the case or proceeding, as a party or otherwise, or by reason of his or her having been convicted of a crime; but the interest or conviction may be shown for the purpose of affecting the credibility of the witness. A defendant in a criminal case or proceeding shall only at his or her own request be deemed a competent witness, and the person's neglect to testify shall not create a presumption against the person, nor shall the court permit a reference or comment to be made to or upon that neglect.

In criminal cases, husband and wife may testify for or against each other. Neither, however, may testify as to any communication or admission made by either of them to the other or as to any conversation between them during marriage, except in cases in which either is charged with an offense against the person or property of the other, in case of spouse abandonment, when the interests of their child or children or of any child or children in either spouse's care, custody, or control are directly involved, when either is charged with or under investigation for an offense under Section 11-1.20, 11-1.30, 11-1.40, 11-1.50, 11-1.60, 12-13, 12-14, 12-14.1, 12-15, or 12-16 of the Criminal Code of 1961 or the Criminal Code of 2012 and the victim is a minor under 18 years of age in either spouse's care, custody, or control at the time of the offense, or as to matters in which either has acted as agent of the other.

A witness who is duly subpoenaed who neglects or refuses to attend any court, under the requisitions of the subpoena, shall be proceeded against and punished for contempt of the court.

Sec. 115-17a. Subpoenas to crime victims. In a post conviction proceeding, before the crime victim may be subpoenaed by the defendant, the defendant must first petition the court and give notice to the victim. At the hearing on the petition, the victim shall be given the opportunity to appear and object to the requested subpoena. At the request of the victim, the State's Attorney shall represent the victim in the proceeding. The court shall grant the request for the subpoena only if and to the extent it determines that the subpoena seeks evidence that is material and relevant to the post conviction hearing. For the purposes of this Section, "crime victim" has the meaning ascribed to it in Section 3 of the Rights of Crime Victims and Witnesses Act.

"Offense involving the sexual exploitation of children" means an offense under Section 11-1.20, 11-1.30, 11-1.40, 11-1.50, 11-1.60, 11-6, 11-6.5, 11-6.6, 11-9.1, 11-14.4, 11-15.1, 11-17.1, 11-18.1, 11-19.1, 11-19.2, 11-20.1, 11-20.1B, 11-20.3, 11-21, 11-23, 11-25, 11-26, 12-13, 12-14, 12-14.1, 12-15, or 12-16 of the Criminal Code of 1961 or the Criminal Code of 2012 or any attempt to commit any of these offenses when the victim is under 18 years of age.

(b) Subpoenas duces tecum. In any criminal investigation of an offense involving the sexual exploitation of children, the Attorney General, or his or her designee, or a State's Attorney, or his or her designee, may issue in writing and cause to be served subpoenas duces tecum to providers of electronic communication services or remote computing services requiring the production of records relevant to the investigation. Any such request for records shall not extend beyond requiring the provider to disclose the information specified in 18 U.S.C. 2703(c)(2). Any subpoena duces tecum issued under this Section shall be made returnable to the Chief Judge of the Circuit Court for the Circuit in which the State's Attorney resides, or his or her designee, or for subpoenas issued by the Attorney General, the subpoena shall be made returnable to the Chief Judge of the Circuit Court for the Circuit to which the investigation pertains, or his or her designee, to determine whether the documents are privileged and whether the subpoena is unreasonable or oppressive.

(c) Contents of subpoena. A subpoena under this Section shall describe the records or other things required to be produced and prescribe a return date within a reasonable period of time within which the objects or records can be assembled and made available.

(c-5) Contemporaneous notice to Chief Judge. Whenever a subpoena is issued under this Section, the Attorney General or his or her designee or the State's Attorney or his or her designee shall be required to provide a copy of the subpoena to the Chief Judge of the county in which the subpoena is returnable.

(d) Modifying or quashing subpoena. At any time before the return date specified in the subpoena, the person or entity to whom the subpoena is directed may petition for an order modifying or quashing the subpoena on the grounds that the subpoena is oppressive or unreasonable or that the subpoena seeks privileged documents or records.

(e) Ex parte order. An Illinois circuit court for the circuit in which the subpoena is or will be issued, upon application of the Attorney General, or his or her designee, or State's Attorney, or his or her designee, may issue an ex parte order that no person or entity disclose to any other person or entity (other than persons necessary to comply with the subpoena) the existence of such subpoena for a period of up to 90 days.

(1) Such order may be issued upon a showing that the things being sought may be relevant to the investigation and there is reason to believe that such disclosure may result in:

(B) flight to avoid prosecution;

(C) destruction of or tampering with evidence;

(D) intimidation of potential witnesses; or

(E) otherwise seriously jeopardizing an investigation or unduly delaying a trial.

A subpoena duces tecum issued under this Section may be enforced pursuant to the Uniform Act to Secure the Attendance of Witnesses from Within or Without a State in Criminal Proceedings.

(g) Immunity from civil liability. Notwithstanding any federal, State, or local law, any person, including officers, agents, and employees, receiving a subpoena under this Section, who complies in good faith with the subpoena and thus produces the materials sought, shall not be liable in any court of Illinois to any customer or other person for such production or for nondisclosure of that production to the customer.
