The Supreme Court is preparing to wade into one of the most significant aspects of the legal battles raging during the second Trump administration, one that could redefine how far federal judges can go in blocking certain presidential actions.

At issue is a growing use of nationwide injunctions in federal courts across the country. These court orders halt federal policies across all 50 states. National injunctions have hindered President Donald Trump from moving forward with his executive order to curtail birthright citizenship, and the Supreme Court will soon examine those decisions by lower courts.
