The Justice Department's Antitrust Division withdrew a 1987 letter, citing "significant competition concerns" about the concentration of proxy advisory market power.

  • Primary Legal Issue: Concentration of proxy advisory market power

  • Statutes Cited: Not specified

  • Court: Not applicable

  • Practical Outcome: Potential enforcement action against Institutional Shareholder Services

How Does This Affect You?

The Justice Department's action clarifies its stance on concentration of market power, creating a compliance obligation for companies relying on proxy advisory services. These companies may wish to review their proxy voting recommendations and consider potential changes due to antitrust enforcement. The shift means lawyers may find it useful to assess potential antitrust enforcement risks under Section 2 of the Sherman Act.

For Lawyers & Advocates

  • Review of pending client matters involving proxy advisory services may reveal potential antitrust enforcement risks under Section 2 of the Sherman Act.

  • Lawyers may consider drafting changes to proxy statements and voting recommendations to take into account potential new regulations.

  • Clients may want to be advised on the potential impact of antitrust enforcement on their use of proxy advisory services, including potential implications for compliance with antitrust regulations.

  • The use of the 1987 letter as precedent in advising clients on proxy advisory services may be reevaluated, considering the potential for changed regulatory interpretation.

  • Companies' risk of non-compliance with antitrust regulations may be assessed, including the potential for enforcement action under the Securities Exchange Act of 1934.

For Law Students

The decision provides an opportunity to examine how courts review regulatory power, specifically in the context of monopolization under Section 2 of the Sherman Act. The core legal doctrine to focus on is the concept of concentration of market power and its implications for antitrust enforcement.
The decision is particularly relevant for the study of:

  • Antitrust Law

  • Securities Regulation

  • Monopolization cases

  • Regulatory compliance
    Comparison to United States v. Grinnell Corp. (1960) and Verizon Communications Inc. v. Law Offices of Curtis V. Trinko (2004) illuminates the doctrinal question of how courts interpret and apply Section 2 of the Sherman Act in cases involving concentration of market power.

For Businesses
