Full Text of 735 ILCS 5/8-802.3
Plain-English Summary
Section 8-802.3 protects the identity of an informant who submits information about a criminal act to a law enforcement agency, or to a community organization acting as an intermediary in reporting to law enforcement, and who requests anonymity. That identity is privileged and confidential, and it is not subject to discovery or admissible in evidence in a proceeding, unless the statute's exceptions apply.
The privilege can be overcome. After an in-camera hearing, a court can find no privilege applies if the party seeking discovery or offering the evidence shows that the informant's identity is sought or offered in a proceeding involving a felony or misdemeanor, that the evidence is not otherwise available, and that either nondisclosure would infringe a constitutional right of the accused or the need for the evidence substantially outweighs the interest in protecting confidentiality.
A separate procedure addresses conflicts of interest. If defense counsel seeks the informant's identity based on a good-faith factual basis that a prior representation of the informant creates a serious potential for an actual conflict, counsel must file a motion. The court can deny it for lack of factual basis, or, if the basis is sufficient, hold a sealed in-camera hearing with the informant outside the presence of all counsel to determine whether an actual conflict exists, and then either deny the motion or notify counsel of the conflict, subject to any nondisclosure conditions the court deems appropriate. The court may impose sanctions necessary to enforce its orders under this section.
Frequently Asked Questions
Can Illinois law enforcement protect the identity of a person who reports a crime anonymously?
Yes. Section 8-802.3 makes the identity of a person who submits crime information to law enforcement, or to an intermediary community organization, privileged and confidential if the person requests anonymity, and it is not subject to discovery or admissible in evidence absent an exception.
When can a court order disclosure of an informant's identity?
After an in-camera hearing, if the party seeking disclosure shows the identity is sought in a felony or misdemeanor proceeding, the evidence is not otherwise available, and either nondisclosure would infringe a constitutional right of the accused or the need for the evidence substantially outweighs the confidentiality interest.
What happens if a defense lawyer previously represented a confidential informant?
Counsel must file a motion alleging a good-faith factual basis for a serious potential conflict of interest. The court can deny the motion for lack of basis, or hold a sealed in-camera hearing with the informant outside all counsel's presence to determine whether an actual conflict exists.
Is the informant's identity privilege absolute?
No. It can be overcome through the court's in-camera hearing process under subsection (b), where the party seeking the informant's identity carries the burden of showing the statutory conditions are met.
Can a court punish a party who violates a disclosure order under this section?
Yes. Section 8-802.3(c) lets the court impose sanctions as necessary to enforce its orders under this section.
