The Department of Justice (DOJ) announced last week that it and the State of North Carolina have reached a settlement with Carolinas Healthcare System / Atrium Health relating to provisions in contracts between the health system and commercial insurers that allegedly restrict payors from “steering” their enrollees to lower-cost hospitals. The settlement comes after two

The Department of Justice (DOJ) and six broadcast television companies reached settlements last week after the DOJ claimed that the companies shared competitively sensitive information that allowed the parties to alter the way prices were set in the television spot advertising market. Assistant Attorney General Makan Delrahim explained in a speech at the ABA Antitrust

Antitrust laws protect competition and consumers. Antitrust enforcement is prevalent in actions concerning manufacturing and consumer goods, among other things. However, recent enforcement activity by the Federal Trade Commission (FTC) and Department of Justice’s Antitrust Division (DOJ) serves as a reminder that the services industry, particularly healthcare services, is not immune to antitrust scrutiny as well.

Antitrust enforcement and healthcare policy were two priorities under President Obama. So, too, was antitrust enforcement within healthcare markets. The current administration prompted speculation on whether it would change its emphasis in any of these respects. We examine in this article whether the Trump Administration, now a year and a half into its term, has shifted focus or instead has stayed in the hunt for antitrust violations in the healthcare industry. As discussed below, the record of healthcare antitrust enforcement actions over the last five years, spanning both administrations, demonstrates that healthcare has been and remains a priority for civil and criminal antitrust enforcement by the US antitrust agencies and state Attorneys General.

Alert: The Supreme Court clarified the principles of international comity this week in a ruling pertaining to the long-running vitamin C antitrust class action litigation. International comity is the recognition a nation shows to the legislative, executive or judicial acts of another nation. Principles of comity state that US courts should defer to the laws of other nations when actions are taken pursuant to those laws. In this week’s ruling, Justice Ginsberg wrote that federal courts should accord respectful consideration to foreign government submissions when analyzing comity issues, but are not bound by them. This ruling vacates the Second Circuit’s decision in the case overturning the jury verdict for the class, and is a win for the class of US purchasers of vitamin C.

WHAT HAPPENED:

  • Senator Elizabeth Warren (D-MA) gave a speech at the Open Markets Institute on December 6 entitled “Three Ways to Remake the American Economy for All”, in which she repeatedly positioned antitrust policy as a tool to rebalance competition between “big, powerful corporations” and “just about everyone else.”

This week, the Federal Trade Commission filed an administrative complaint against the Louisiana Real Estate Appraisers Board (LREAB). This complaint is the FTC’s first against a state licensing board since it prevailed in the Supreme Court in the decision in NC State Board of Dental Examiners v. FTC in 2015. There, the Court held that immunity from the antitrust laws under the state action doctrine does not apply to a state board that regulates an industry if: 1) a majority of the board members are active participants in the market they are regulating, and 2) the board has not been actively supervised by the state. McDermott reported in detail about the NC Board of Dental Examiners at the time of the decision. The complaint comes on the tail of a settlement agreement between the FTC and a trade organization, the American Guild of Organists, as reported this week.

FTC alleges that the LREAB violated Section 5 of the Federal Trade Commission Act by unreasonably restraining price competition for real estate appraisal services provided to appraisal management companies (AMCs) in Louisiana.
