On August 7, U.S. District Court Judge Deborah Boardman, a Biden appointee, converted CASA Inc. v Trump, 8:25cv-201, into a class action. This is the birthright citizenship lawsuit that the U.S. Supreme Court had been involved in. In this lawsuit, the U.S. Supreme Court had struck down nationwide injunctions issued by U.S. District Courts unless either the case has been filed by a state, or the case is a class action.
On remand, the U.S. District Court converted the case into a class action and then again enjoined the Presidential order on birthright citizenship. Thanks to Thomas Jones for this news.
