Illinois General Assembly - Illinois Compiled Statutes

Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

(735 ILCS 5/3-107) (from Ch. 110, par. 3-107)

Sec. 3-107. Defendants.

(a) Except as provided in subsection (b), (b-1), or (c), in any action to review any final
decision of an administrative agency, the administrative agency and all
persons, other than the plaintiff, who were parties of record to the
proceedings before the
administrative agency shall be made defendants. The method of service of the decision shall be as provided in the Act governing the procedure before the administrative agency, but if no method is provided, a decision shall be deemed to have been served either when a copy of the decision is personally delivered or when a copy of the decision is deposited in the United States mail, in a sealed envelope or package, with postage prepaid, addressed to the party affected by the decision at his or her last known residence or place of business.  The form of the summons and the issuance of alias summons shall be according to rules of the Supreme Court.

No action for administrative review shall be dismissed for lack of
jurisdiction: (1) based upon misnomer of an agency, board, commission, or party that is properly served with summons that was issued in the action within the applicable time limits; or (2) for a failure to name an employee, agent, or member, who
acted in his or her official capacity, of an administrative agency, board,
committee, or government entity where a timely action for administrative review has been filed that identifies the final administrative decision under review and that makes a good faith effort to properly name the administrative agency, board,
committee, or government entity.  Naming the director or agency head, in his or her official
capacity, shall be deemed to include as defendant the administrative agency,
board, committee, or government entity that the named defendants direct or
head.  No action for administrative review shall be dismissed for lack of
jurisdiction based upon the failure to name an administrative agency, board,
committee, or government entity, where the director or agency head, in his or
her official capacity, has been named as a defendant as provided in this
Section.

If, during the course of a review action, the court determines that an agency or a party
of record to the administrative proceedings was not made a defendant as
required by the preceding paragraph, then the
court shall grant the plaintiff 35 days from the date of the determination in
which to name and serve the unnamed agency or party as a defendant.  The court shall
permit the newly served defendant to participate in the proceedings to the
extent the interests of justice may require.

appeals under Division 13 of Article 11 of the Illinois Municipal Code, "parties of
record" means only the zoning board of appeals and applicants before the

appeals with respect to the decision appealed from.  The notice shall be
mailed within 2 days of the filing of the action.  The notice shall state
the caption of the action, the court in which the action is filed, and the
names of the plaintiff in the action and the applicant to the zoning board
of appeals.  The notice shall inform the person of his or her right to
intervene.  Each person who appeared before and submitted oral testimony

decision appealed from shall have a right to intervene as a defendant in
the action upon application made to the court within 30 days of the mailing
of the notice.
