In its recent birthright citizenship ruling, Trump v. CASA, the Supreme Court noted that plaintiffs could still seek broad relief by filing such class action lawsuits that would join together large groups of individuals facing the same injury from the law they were challenging.

Federal District Judge Joseph Laplante has certified a class consisting of all current and future children who stand to lose citizenship rights because of Trump's order, and issued a preliminary injunction barring enforcement of the order against all members of that class.
