No commissioner or employee of an Authority shall acquire any interest direct or indirect in any project or in any property included or planned to be included in any project, nor shall he have any interest direct or indirect in any contract or proposed contract for materials or services to be furnished or used in connection with any project. If any commissioner or employee of any Authority owns or controls an interest direct or indirect in any property included in any project, which was acquired prior to his appointment or employment, he shall disclose the same in writing to the Authority and such disclosure shall be entered upon the minutes of the Authority.
Nothing contained in this Act or in any other law shall be construed to preclude a tenant of an Authority from serving as an appointed commissioner of that Authority. No part of this Act or any other law shall be construed in such a way as to inhibit the tenant commissioner in the lawful exercise of the powers and duties of his or her office.
