Overview

• In its June 27 decision in Trump v. CASA, the Supreme Court limited nationwide injunctions but affirmed that class actions under Federal Rule 23 remain a pathway to broad relief.
• On July 10, U.S. District Judge Joseph Laplante certified a class of children born to noncitizen parents and issued a preliminary injunction barring enforcement of Executive Order 14160 nationwide.
• The Trump administration has filed an emergency appeal to the First Circuit seeking to lift Laplante’s injunction and restore enforcement of the birthright citizenship order.
• If higher courts reverse the class-action block and no other nationwide stay is in place, the executive order could take effect in jurisdictions not covered by existing litigation, risking a patchwork of state-by-state implementation.
• The case underscores ongoing debates over the balance of executive power, the scope of judicial remedies, and the use of class actions to achieve nationwide blocks after universal injunctions were curtailed.
