Are Nationwide Injunctions by a Single Judge a Needed Check on Presidents?
Universal injunctions barely existed before the 1960s; the Supreme Court limited them in 2025, and class actions and appeals remain available for broad relief.
The claim
Defenders say that when a president issues an order that likely violates the law, a single district judge should be able to block it everywhere, because relief for only the plaintiffs would leave millions of others exposed to harm and would force repeated lawsuits.
The answer in three points
- Courts decide cases between parties. Article III extends the judicial power to cases and controversies, and the usual remedy protects the people who sued. A judge who blocks a policy for the entire country on the strength of one case claims a power that the founders did not give to a single trial court.
- Universal injunctions have a short history. They were almost unknown before the 1960s, and their use grew sharply in recent years under presidents of both parties, which led to forum shopping, where litigants pick a judge likely to rule for them. A system that lets one judge in one district set national policy invites politics.
- In Trump v. CASA (2025), the Supreme Court held that universal injunctions likely exceed the equitable authority that federal courts have under the Judiciary Act of 1789. Relief is still available through class actions, state suits and appeals, and the Court can speak for the whole nation when it decides the merits.
Courts check the government most effectively when they stay within the limits of their own authority.
The numbers
- Trump v. CASA, Inc. was decided by the Supreme Court in June 2025, holding that universal injunctions likely exceed the equitable authority of federal courts.
- The Judiciary Act of 1789 gave federal courts jurisdiction in equity, which the Court has read as limited to the relief traditionally available in 1789.
- Article III, Section 2 extends the judicial power to cases and controversies, according to the text of the Constitution.
What they will say next
"Relief only for plaintiffs leaves others unprotected." Class actions allow relief for groups, and the Court left them open. A final ruling by the Supreme Court sets the law for everyone.
"Presidents of both parties have faced these." They have, which is why the rule matters to both. A power that one side uses today will be used by the other tomorrow.
"Delays mean harm in the meantime." Courts can expedite appeals, and emergency review by the Supreme Court is available. Speed is a reason to reform procedure and not to expand the power of one judge.
"Judges check illegal executive acts." They do, in the cases before them, and nothing here limits their duty to rule against unlawful actions.
The best check on the executive is a court acting within its own limits.
"The ruling leaves millions waiting for relief." Class actions, appeals and prompt Supreme Court review can reach large numbers of people. The ruling concerns the scope of a trial judge's equitable power, and it leaves the courts' power to decide cases untouched.
