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 5/3-105

(735 ILCS 5/3-105) (from Ch. 110, par. 3-105)

Sec. 3-105. Service of summons.

Summons issued in any action to review
the final administrative decision of any administrative agency shall be
served by registered or certified mail on the administrative agency and on
each of the other defendants except in the case of a review of a final
administrative decision of the regional board of school trustees, regional
superintendent of schools, or State Superintendent of Education, as the
case may be, when a committee of 10 has been designated as provided in
Section 7-6 of the School Code, and in such case only the administrative
agency involved and each of the committee of 10 shall be served. The method of service shall be as provided in the Act governing the procedure before the administrative agency, but if no method is provided, summons shall be deemed to have been served either when a copy of the summons 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 based upon the failure to serve summons on an employee, agent, or
member of an administrative agency, board, committee, or government entity,
acting in his or her official capacity, where the administrative agency, board,
committee, or government entity has been served as provided in this Section.
Service on the director or agency head, in his or her official capacity, shall
be deemed service on the administrative agency, board, committee, or government
entity.  No action for administrative review shall be dismissed for lack of
jurisdiction based upon the failure to serve summons on an administrative
agency, board, committee, or government entity, acting, where the director or
agency head, in his or her official capacity, has been served as provided
in this Section.
Service on the administrative agency shall be made by the clerk of the
court by sending a copy of the summons addressed to the agency at its main
office in the State. The clerk of the court shall also mail a copy of the
summons to each of the other defendants, addressed to the last known place
of residence or principal place of business of each such defendant. The
plaintiff shall, by affidavit filed with the complaint, designate the last
known address of each defendant upon whom service shall be made. The
certificate of the clerk of the court that he or she has served such
summons in pursuance of this Section shall be evidence that he or she
has done so.

The changes to this Section made by this amendatory Act of the 95th General Assembly apply to all actions filed on or after the effective date of this amendatory Act of the 95th General Assembly.
