Antitrust and Unfair Competition Law

Competition: SPRING 2023, Vol 33, No. 1

SHOULD CALIFORNIA ADOPT REVISIONS PROPOSED BY CONGRESS AND THE NEW YORK STATE LEGISLATURE TO ADDRESS SINGLE-FIRM CONDUCT?

By Susannah Torpey, Brandon Annette and Quinlan Cummings1

California’s primary antitrust statute, the Cartwright Act, prohibits any contract combination or conspiracy in restraint of trade or commerce, mirroring language codified in federal law.2However, the Cartwright Act is silent on single-firm monopolies, a direct departure from its federal law counterpart, the Sherman Act. Section 2 of the Sherman Act ("Section 2") addresses such monopolies by making it unlawful to "monopolize, or attempt to monopolize . . . any part of the trade or commerce among the several States, or with foreign nations."3 The Cartwright Act, by contrast, only outlaws "trusts," defined by the statute as concerted action by "two or more persons" to restrain trade.4Thus, the Cartwright Act does not reach unilateral conduct that restrains competition.5 As such, anticompetitive conduct that has been successfully prosecuted under Section 2, such as predatory pricing,6 patent misuse,7 anticompetitive product redesign,8 and refusals to deal,9 is not proscribed by the Cartwright Act.10

California is not alone in limiting antitrust proscription to concerted conduct. For example, New York’s little Sherman Act, the Donnelly Act, currently does not reach unilateral conduct. However, the recent New York State Senate Bill S933A looks to Section 2 and European abuse-of-dominance standards for guidance on prohibiting predatory and exclusionary conduct by dominant single firms. Further, while federal law on its face bans exclusionary conduct by monopolists under Section 2, critics have argued that Section 2 of the Sherman Act itself has been under-enforced and is ineffective at holding monopolists accountable for anticompetitive conduct over the past two decades.11 In part to combat this issue, Senator Amy Klobuchar (D-MN) introduced the federal Competition and Antitrust Law Enforcement Reform Act of 2021 ("CALERA"), which endorses a European framework while focusing on increasing merger standards as a means of preventing the formation of monopolies indirectly.
