70 ILCS 1842/85
(c) The Port District may act (i) through its governing and administrative body for the Port District as a whole, as provided in this subsection or (ii) individually through the actions of a city council of a participating municipality solely for the portion of Port District within that participating municipality's corporate limits, as provided in subsection (d).
All actions by the governing and administrative body shall be by ordinance or resolution by the affirmative vote of a majority of the city councils of the participating municipalities. However, the governing and administrative body may not take any action solely within one participating municipality without the approval of the majority of members on that participating municipality's city council. If an ordinance or resolution adopted by the governing and administrative body conflicts with an ordinance or resolution relating to Port District purposes adopted of a city council of a participating municipality, the ordinance or resolution adopted by the city council of the participating municipality controls unless the majority of members on that participating municipality's city council approved the ordinance or resolution of the governing and administrative body.
(d) All actions regarding the Port District within each participating municipality shall be by ordinance or resolution and, except as otherwise provided in this Act, the affirmative vote of a majority of the city council of the participating municipality. The chief elected officer of the city council of a participating municipality is entitled to vote on all matters coming before the city council related to the Port District within the participating municipality, notwithstanding any other provision of law.
All ordinances, resolutions, and proceedings of the city council of a participating municipality and all documents and records in its possession are public records and open to public inspection at the office of the participating municipality, except documents and records that are kept or prepared by the participating municipality for the Port District within the municipality's corporate limits for use in negotiations, legal actions, or proceedings related to that portion of the Port District within the municipality's corporate limits.
