WASHINGTON — Robert E. Primus filed a federal lawsuit today challenging his dismissal from the Surface Transportation Board. Primus was the lone member of the STB to vote against the 2023 Canadian Pacific-Kansas City Southern merger. Primus’s lawsuit — filed in the U.S. District Court for the District of Columbia against the president, STB Chairman Patrick Fuchs, and the STB — says the president unlawfully removed him from office. Congress made clear when creating the Surface Transportation Board that the agency should be independent and above politics. Democracy Forward is committed to supporting his efforts to continue his important work as a member of the Surface Transportation Board,” Democracy Forward CEO Skye Perryman said in a statement.
