About Antitrust Litigation Law in Chicago, United States

In Chicago, as in the rest of the United States, antitrust laws aim to protect consumers and other businesses from unfair business practices such as price fixing, market allocation, bid rigging, and abuse of dominant market positions. Both federal and Illinois state laws apply to antitrust matters in Chicago. Typical antitrust cases may involve lawsuits brought by individuals, businesses, or government agencies against companies accused of violating these laws.
