Has the U.S. Supreme Court issued an injunction specifically preventing Donald Trump from signing executive orders?

1. What the Court actually did: curtailed universal injunctions, not presidential signing power

In a 6–3 decision consolidated as Trump v. CASA, the Supreme Court reviewed whether federal judges may issue “universal” injunctions that bar government action for nonparties and concluded that equitable relief must be tethered to traditional, party-specific principles—thereby limiting the availability of nationwide injunctions and granting partial stays of several district-court orders that had barred enforcement of President Trump’s birthright-citizenship executive order ^{[1] [4] [3]}.

2. What the decision meant in practice for the birthright citizenship order

The Court did not reach the merits of the birthright-citizenship executive order; instead it vacated or narrowed universal injunctions blocking that order and allowed, in practical effect, the order to take effect after a 30‑day window in which lower courts could recalibrate relief—so the high court’s decision opened the door to partial enforcement in some places but did not itself command agencies to implement the policy nationwide, nor did it enjoin the President from signing orders generally ^{[1] [5] [6]}.

3. Lower courts had previously blocked enforcement, prompting the appeal

Before the Supreme Court intervened, multiple federal district courts across states such as Maryland, Massachusetts, New Hampshire, and Washington had entered nationwide preliminary injunctions or temporary restraining orders preventing executive-branch officials from enforcing the citizenship order and other Trump actions, and the government sought relief at the Supreme Court to limit those broad injunctions ^{[2] [7] [4]}.

4. Competing narratives: government triumph, civil‑rights alarm

The White House framed the ruling as a sweeping victory for executive authority and the “rule of law,” arguing the decision stopped what it called judicial overreach in issuing nationwide blocks on presidential policies ^[8], while civil-rights groups such as the ACLU warned the narrowing of universal injunctions could permit partial enforcement that harms vulnerable people and sent preliminary injunctions back to lower courts for further consideration ^[6].

5. Why the question of “preventing signing” is a category error

An injunction that literally prevents a president from signing an executive order would be an unusual relief—courts traditionally enjoin enforcement, not the act of signing; the Supreme Court’s ruling addressed the scope of remedies federal courts may grant (i.e., whether relief can bind non-parties nationwide), not a prohibition on the President’s formal act of issuing orders, and it left open the ability of plaintiffs to seek tailored or class-wide relief in lower courts ^{[1] [3] [4]}.

6. The next stages: merits still unresolved and consequences uncertain

Because the Court declined to resolve the constitutional questions—most notably whether the birthright-citizenship order violates the Fourteenth Amendment—the underlying disputes remain in play in lower courts and may return to the Supreme Court on the merits, meaning enforcement and legal constraints will be determined through subsequent litigation rather than by a categorical injunction against executive-signing ^{[1] [3]}.

7. The political and procedural subtext

Observers note the ruling reshapes how challengers seek relief—limiting “nationwide” injunctions may force more class actions or staggered litigation and, as critics point out, could give administrations more breathing room to implement policies while suits proceed—a practical change that benefits the current administration and reflects ideological splits among the justices about judicial power and remedies ^{[2] [7] [3]}.
