Insofar as this Act authorizes the Authority to take or authorize any action notwithstanding or in lieu of any ordinance, rule, regulation or power of any unit of local government; or provides that any unit of local government restrictions are not effective with regard to the Authority or provides that any power or action of any unit of local government is subject to any power or action of the Authority, this Act is an express limitation on the powers of home rule municipalities and counties within the meaning of paragraph (g) of Section 6 of Article VII of the Illinois Constitution. No such action by the Authority shall be such a limit unless taken pursuant to an ordinance which is passed by at least seven members of the Board and which specifically states that it is a limit on the home rule unit; and provided further that this Act is not a limit on the power of home rule units to license, tax, franchise or regulate taxicabs except for services provided pursuant to purchase of service agreements. Except as provided in this Section, this Act is not a limit on any home rule unit.
