Synopsis As Introduced Amends the Illinois Emergency Management Agency Act by creating the Fair Business Treatment Law. Provides that if the Governor issues a proclamation declaring a disaster under the Act or an executive order relating to the same disaster for which the proclamation was issued, and the proclamation or executive order includes one or more restrictions upon the retail sale of goods or services within Illinois, the restriction must be enforced so as not to favor any one industry classification of persons engaged in the business of selling tangible personal property at retail over any other industry classification of such persons. Requires the Illinois Emergency Management Agency to develop a protocol for the fair enforcement of proclamations declaring a disaster under the Act. Requires the Agency, in developing and maintaining the protocol, to consult with relevant private sector stakeholders, including representatives of the Illinois retail sales industry. Effective immediately.
