The Supreme Court, in a 6-3 ruling, restricted federal district judges from issuing nationwide injunctions against executive orders, a move that will reshape how federal policies are contested. The case involved an immigration order changing how birthright citizenship applies to children of undocumented parents, a shift opponents say violates the Fourteenth Amendment.

New York Attorney General Letitia James led state efforts to block the policy, arguing it threatens constitutional rights and family stability. The majority, however, held that broad injunctions exceed district-court authority, meaning challenges must now proceed case by case instead of halting a policy nationwide.

Legal experts predict sweeping effects beyond immigration, influencing challenges to environmental, healthcare, and financial regulations. The decision marks a turning point in the balance of power between courts and the executive branch—tightening judicial reach while forcing opponents of federal actions to pursue narrower, more complex legal strategies.
