Antitrust Law - Study B-750

    In 2022, the Legislature authorized the Commission to study the following issues:

(1) Whether the law should be revised to outlaw monopolies by single companies as outlawed by Section 2 of the Sherman Act, as proposed in New York State’s “Twenty-First Century Anti-Trust Act” and in the “Competition and Antitrust Law Enforcement Reform Act of 2021” introduced in the United States Senate, or as outlawed in other jurisdictions.

(2) Whether the law should be revised in the context of technology companies so that analysis of antitrust injury in that setting reflects competitive benefits such as innovation and permitting the personal freedom of individuals to start their own businesses and not solely whether such monopolies act to raise prices.

(3) Whether the law should be revised in any other fashion such as approvals for mergers and acquisitions and any limitation of existing statutory exemptions to the state’s antitrust laws to promote and ensure the tangible and intangible benefits of free market competition for Californians ... (2022 Cal. Stat. res. ch. 147.)

    Materials related to the Commission’s work on that topic will be collected on this page.
