The Office of the Attorney General's Antitrust Division is responsible for enforcing the antitrust provisions of Washington's Unfair Business Practices-Consumer Protection Act. The division also brings actions in federal court under Sections One and Two of the Sherman Act. The Antitrust Division investigates complaints about potential anti-competitive activity.
Our office looks for:
Price-fixing and other forms of collusion. Price-fixing includes an explicit agreement among competitors to raise, fix, or otherwise maintain the price at which their goods or services are sold to the detriment of either the competitive marketplace or consumers.
Business mergers and monopolistic practices that would result in reduced competition and harm to consumers.
