This is an action filed by University of California (“UC”) researchers against President Donald Trump, the Department of Government Efficiency (“DOGE”), the National Science Foundation, the National Endowment for the Humanities, the Environmental Protection Agency, and various other defendants, challenging the termination and/or suspension of their previously approved federal research grants. The plaintiffs seek injunctive relief and class certification on behalf of a class of all UC researchers across the ten-campus UC system whose research grants have been or will be terminated, denied, suspended, or reduced by any of the defendants pursuant to Executive Order Nos. 14151, 14154, 14158, 14168, 14173, 14217, 14238, and/or 14222, and/or other directives of the Trump administration or DOGE, from and after January 20, 2025. The plaintiffs assert that these orders and directives violate separation of powers principles, the First Amendment guarantee of free speech, the Fifth Amendment guarantee of due process, the Impoundment Control Act of 1974, statutes requiring agencies to fulfill congressionally defined missions, and the Administrative Procedure Act (“APA”).
