2021 Illinois Compiled Statutes|Chapter 65 - MUNICIPALITIES|65 ILCS 5/ - Illinois Municipal Code.|Article 1 - General Provisions

 (from Ch. 24, par. 1-2-4)Sec. 1-2-4.         All ordinances of cities, villages and incorporated towns  imposing any fine, penalty, imprisonment, or forfeiture, or making any  appropriation, shall (1) be printed or published in book or pamphlet  form, published by authority of the corporate authorities, or (2) be  published at least once, within 30 days after passage, in one or more  newspapers published in the municipality, or if no newspaper is  published therein, then in one or more newspapers with a general  circulation within the municipality.  If there is an error in printing,  the publishing requirement of this Act shall be satisfied if those  portions of the ordinance that were erroneously printed are republished,  correctly, within 30 days after the original publication that contained the  error.  The fact that an error occurred in publication shall not affect the  effective date of the ordinance so published. If the error in printing is not  corrected within 30 days after the date of the original publication that  contained the error, as provided in the preceding sentence, the corporate  authorities may by ordinance declare the ordinance that was erroneously  published to be nevertheless valid and in effect no sooner than  the tenth day after the date of the original publication, notwithstanding  the error in publication, and shall order the original ordinance to be  published once more within 30 days after the passage of the validating  ordinance.  In municipalities with less than  500 population in which no newspaper is published, publication may  instead be made by posting a notice in 3 prominent places within the  municipality.  An annual appropriation ordinance adopted under Section  8-2-9 shall take effect upon passage, but no other ordinance  described in this paragraph shall take effect until 10 days after it  is so published, except that an ordinance imposing a municipal  retailers' occupation tax adopted under Section 8-11-1, or a Tourism,  Convention and Other Special Events Promotion Tax adopted under Section  8-3-13, or effecting a change in the rate thereof shall take effect on  the first day of the month next following the expiration of the 30 day  publication period. However, ordinances establishing rules and  regulations for the construction of buildings or any part thereof, or  for the development or operation of camps accommodating persons in house  trailers, house cars, cabins or tents, where such rules and regulations  have been previously printed in book or pamphlet form, may by their  terms provide for the adoption of such rules and regulations or portions  thereof by reference thereto without further printing, or publication,  if not less than one copy of such rules and regulations in  book or  pamphlet form has been filed in the office of the clerk of the  municipality for use and examination by the public at least 30 days  prior to the adoption thereof.All other ordinances, resolutions and motions, shall take effect upon  their passage unless they otherwise provide.This Section applies to incorporated towns even if the Section's  provisions are in conflict with the charters of such incorporated towns.Anything in this Section to the contrary notwithstanding, any  ordinance which contains a statement of its urgency in the preamble or  body thereof, other than an ordinance adopted under Article 8 of this  Code, may take effect immediately upon its passage provided that the  corporate authorities, by a vote of 2/3 of all the members then holding  office, so direct. The decision of the corporate authorities as to the  urgency of any ordinance shall not be subject to judicial review except  for an abuse of discretion.    (Source: P.A. 89-266, eff. 1-1-96.)
