(50 ILCS 20/6) (from Ch. 85, par. 1036)
    Sec. 6. Each person appointed as a member of the Board of Commissioners shall qualify by taking and subscribing to an oath to uphold the Constitution of the United States and of the State of Illinois and to well and faithfully discharge his duties, which oath shall be filed with the Secretary of the Commission.
    Commissioners shall be persons experienced in real estate management, building construction or finance. The fact that a person is an officer or employee of any municipal corporation, including the county seat or county board or any municipality with 3,000 or more inhabitants which adopted the original resolution or any other municipal corporation which joined in the organization of the Commission, shall not disqualify that person from being a Commissioner of a Public Building Commission. No person who is appointed as a Commissioner of a Public Building Commission shall have a financial interest in the creation of or in the continued existence of the Public Building Commission. No Commissioner shall acquire any interest, direct or indirect in any contract or proposed contract of the Public Building Commission, or in any land, building or buildings or other property or facilities in which the Public Building Commission has an interest. If any Commissioner at any time holds or controls an interest, direct or indirect in any property which the Public Building Commission is about to acquire, he shall disclose the same in writing to the Commission and such disclosure shall be entered upon the minutes of the Board of Commissioners.
