WHAT HAPPENED:

  • On Thursday, November 16, 2017, newly confirmed Assistant Attorney General for Antitrust Makan Delrahim, speaking at the American Bar Association Section of Antitrust Law’s Fall Forum, explained where antitrust enforcement fits in the broader Trump administration effort to reduce federal regulations.

On September 14, 2017, Senator Amy Klobuchar (D-MN), introduced new legislation to curtail market concentration and enhance antitrust scrutiny of mergers and acquisitions. As the Ranking Member of the Senate Judiciary Committee’s Subcommittee on Antitrust, Competition Policy and Consumer Rights, Klobuchar is the leading Senate Democrat for antitrust issues.

Two bills were submitted to the Senate: the Consolidation Prevention and Competition Promotion Act (CPCPA) and the Merger Enforcement Improvement Act (MEIA). The CPCPA is co-sponsored by Senators Kirsten Gillibrand (D-NY), Richard Blumenthal (D-CT) and Ed Markey (D-MA). The MEIA is co-sponsored by Senators Blumenthal, Markey and Gillibrand, along with Senators Patrick Leahy (D-VT), Al Franken (D-MN), Cory Booker (D-NJ), Dick Durbin (D-IL), Mazie Hirono (D-HI) and Tammy Baldwin (D-WI). Both bills propose amendments to the Clayton Act. Earlier this year, Senate democrats announced these legislative proposals as part of their “A Better Deal” antitrust agenda.

WHAT DO THE BILLS PROPOSE:

  • Notably, the CPCPA proposes to revise the Clayton Act so that in challenging an acquisition, the Federal Trade Commission (FTC) and Department of Justice (DOJ) would only have to show that the proposed transaction materially lessens competition rather than significantly lessens competition, which is the current standard. The legislation defines “materially lessens competition” to mean “more than a de minimis amount.” This change would reduce the burden of proof for the government in challenging an acquisition.
