Antitrust enforcement is an important component of a sound free-market economy. Competitive marketplaces established through vigorous antitrust enforcement help consumers by ensuring fair prices, an array of products to choose from, increased quality, and innovation through the market. Diligent antitrust enforcement also helps businesses by protecting them from unfair competition and helping to establish a level playing field on which to compete.
The Attorney General’s Antitrust Law Section enforces California’s antitrust laws both civilly and criminally, and federal antitrust laws civilly, through business merger/acquisition reviews, investigations of potential violations of the law, and, where necessary, litigation. The Section has been engaged in these matters for many decades.
Healthcare-related competition matters are handled by our Healthcare Rights and Access Section. The Attorney General's recent antitrust enforcement activities have spanned a wide range of business industries. For more details, see our most recent press releases below:
