Dorrell, et al. v. Constellation Energy, et al. Antitrust Class Action Litigation

On July 11, 2025, an antitrust class action lawsuit was filed in the United States District Court for the District of Maryland on behalf of a putative class against Entergy Corporation, 26 other entities alleged to own and/or operate commercial nuclear power plants in the United States (together with Entergy Corporation, the “nuclear defendants”), and two consulting companies. The class action complaint purports to be brought on behalf of all persons employed in nuclear power generation by the nuclear defendants and their subsidiaries and related entities in the United States from May 1, 2003 to the present. The plaintiffs primarily allege that the nuclear defendants, together with the consulting company defendants, violated Section 1 of the Sherman Act, 15 U.S. Code Chapter 1 by conspiring to suppress compensation and exchange collective bargaining agreement and wage information through a trade group, a consulting firm, and direct communications, including while in attendance at conferences, from May 2003 to the present. The plaintiffs are seeking unspecified monetary damages, including treble damages, interest, injunctive relief, attorney’s fees, and costs. In December 2025 the defendants filed a motion to dismiss. In August 2026 the United States District Court for the District of Maryland granted the defendants’ motion to dismiss, without prejudice, giving the plaintiffs 45 days to amend their complaint to cure the deficiencies. In September 2026 plaintiffs submitted a motion seeking leave to file a second amended complaint, which adds the Institute of Nuclear Power Operations as a defendant and includes additional allegations against the original defendants.
