The Supreme Court issued a set of rulings that expand presidential removal authority, block the administration’s tariff power under the Emergency Powers Act and reject limits on birthright citizenship.Justices also upheld state bans on transgender girls in female school sports under Title IX, allowed Mississippi to count mail-in ballots arriving within five days of Election Day, and made it harder to challenge state redistricting under the Voting Rights Act.The court barred the immediate firing of Federal Reserve governor Lisa Cook, allowed the end of Temporary Protected Status for more than 356K people, and struck down federal limits on coordinated campaign spending, easing party fundraising.The decisions will require refunds exceeding $166B for tariffs, leave many immigration and election choices to state officials, and sharpen constitutional fights over executive power while prompting swift political reactions.
