About Antitrust Law in Illinois, United States

Antitrust law in Illinois is designed to promote fair competition and prevent unlawful restraints on trade, monopolistic practices, and unfair business conduct. These laws ensure that businesses compete fairly and that consumers benefit from competitive prices and choices. While federal antitrust laws such as the Sherman Act and Clayton Act apply nationwide, Illinois also enforces its own statutes to address anticompetitive behavior within the state.

Why You May Need a Lawyer

Antitrust issues can arise in a variety of business and consumer contexts. Common situations where you might need legal help include:

  • Suspecting a competitor or supplier of price fixing, bid rigging, or market allocation
  • Facing allegations of forming a cartel or engaging in collusion
  • Mergers or acquisitions that may reduce competition in Illinois markets
  • Dealing with exclusive dealing agreements or tying arrangements that limit consumer choice
  • Experiencing retaliation or exclusionary conduct by a dominant company
  • Receiving subpoenas or investigation requests from state or federal antitrust authorities
  • Needing compliance advice for advertising, distribution, or sales strategies
  • Suing another business or defending your own against antitrust claims
Antitrust law is complex and violating these laws can result in severe penalties. Consulting a lawyer can help protect your rights and ensure you comply with both state and federal regulations.

Local Laws Overview

In Illinois, the primary state law governing anticompetitive conduct is the Illinois Antitrust Act. This law mirrors many aspects of federal antitrust statutes, prohibiting contracts, combinations, or conspiracies that restrain trade or commerce within Illinois. Key aspects include:

  • Prohibition of Restraint of Trade: Agreements among businesses that restrict competition, fix prices, or divide markets are illegal.
  • Monopolization: Actions taken to acquire or maintain monopoly power in any market are forbidden.
  • Mergers and Acquisitions: Transactions that may substantially lessen competition within Illinois can be challenged.
  • Civil and Criminal Penalties: Both individuals and corporations can face significant fines and even imprisonment for violations.
  • Private Right of Action: Individuals and businesses harmed by antitrust violations can file civil suits and may recover damages.
The Illinois Attorney General has the authority to investigate and bring actions to enforce antitrust laws in the state, often coordinating with federal agencies when necessary.
