Welcome to the NAAG State Antitrust Litigation Database

NAAG created this database to:

  • Provide a single authoritative and comprehensive source for all antitrust cases brought by state attorneys general.
  • Give practitioners, academics, and the general public a complete view of the state attorney general role in antitrust enforcement in the United States.
  • Provide factual background and empirical evidence about how state attorneys general enforce state and federal antitrust laws.

The database focuses on criminal and civil cases from 1990 to the present, with earlier cases from a few states. It covers both multistate cases and those brought by a single state. The database includes the docket number and the court where the case was filed, as well as the case citation, where available. You can see whether a federal antitrust agency was involved in the case, either in a parallel, joint or independent action.

Another significant feature of the database is the ability to find key documents from most cases, including significant pleadings, like motions to dismiss, as well as decisions and orders by the court. The State Antitrust Litigation database is the only online source for many of these documents.

The database can be searched using full-text or sorted by:

  • Lead state
  • Year the case was brought
  • Industry involved
  • Name of the defendant
  • Type of antitrust action

This database is a work in progress. Additional cases will continue to be added. We welcome comments, suggestions, or corrections on both the content and the format. All comments should be sent to NAAG’s Antitrust Counsel, Emily Myers at emyers@naag.org.

The Role of Attorneys General in Antitrust Enforcement

Along with the U.S. Department of Justice and the Federal Trade Commission, state attorneys general are the primary enforcers of federal antitrust laws, in addition to bringing cases under state antitrust statutes in their states.

State attorneys general have enforced the antitrust laws since the nineteenth century, but their efforts increased dramatically after 1990, when the states formed the NAAG Multistate Antitrust Task Force. Through the Antitrust Task Force, state and territory attorneys general work closely together to protect their consumers by bringing antitrust cases in a wide variety of industries, including pharmaceuticals, health care and agriculture. Individual attorneys general also prosecute bid-rigging on public contracts of all kinds.
