The Limits of Judicial Power: Nationwide Injunctions After Trump v. CASA, Inc.
While our Constitution has shed light on many complex legal matters, it is unrealistic to expect that a two hundred and thirty-eight-year-old document will cover modern issues that have developed through judicial practice over the years. One such modern dilemma is the question of the nationwide injunction: a court order that stops the federal government from enforcing a law against everyone rather than those who filed the lawsuit. The power of a district judge to issue a nationwide injunction is explored in Trump v. CASA, Inc., which was very recently decided on June 27th, 2025. For a judge to be able to issue such an injunction is extremely controversial; the judge holds the power to benefit or harm an entire community as a consequence of their decision. Ideally, whether or not a judge should be able to do this depends on the specific situation. While nationwide injunctions should generally be limited, they should still be available as protection against gross violations of constitutional protections.
To begin, Trump v. CASA, Inc. began as a result of President Donald Trump’s issuance of Executive Order 14160. This Executive Order essentially attempted to deny automatic birthright citizenship to children born in the United States whose parents do not have lawful status or hold temporary legal visas. As a result, several immigrant advocacy groups such as CASA (and other entities) sued the Trump administration, arguing that this Order violated the Fourteenth Amendment. The constitutionality of this Executive Order was not the focus of the case, however. Instead, the matter at hand was the fact that many federal district judges issued nationwide injunctions - orders that stopped the enforcement of the Executive Order for everyone rather than just the plaintiffs of the case - and whether or not the district judges had the ability to do so.
Ultimately, the Supreme Court ruled that federal lower courts do not have the legal authority to issue nationwide injunctions, reasoning that Congress never gave the lower courts the statutory authority to do so. Instead, the concept of limited relief was reinforced, meaning that the injunction would only apply to the plaintiffs that introduced the case. Notably, Trump v. CASA, Inc. did not rule on the constitutionality of Trump’s Executive Order regarding birthright citizenship; it focused primarily on the lower court’s ability to obstruct the enforcement of the Order universally.
Of course, this decision raised many controversial questions. For one, critics began to question if this ruling meant that the Court was indirectly implying that some basic constitutional matters could have different forms in different parts of the country. For example, they questioned, if a federal policy one day decides that a fundamental right in the Constitution - women’s right to vote, for instance - is no longer valid, the lower courts would not be able issue nationwide relief. Although this is hypothetical, the nature of the concern is the same. It is worrying to some that a tool of protection has been made illegal.
At the same time, the ruling gained many supporters. The supporters contended that one judge should not have the power to freeze a national policy because a situation of that sort could lead to an imbalance of power. Furthermore, it was argued, the absence of this ruling would encourage “judge shopping” - a practice in which litigants choose specific courthouses to file lawsuits in to ensure a favorable outcome, including a possible nationwide injunction. Finally, supporters of the government’s ruling also discussed the fact that the lower courts do not have the historical authority to issue remedies to the parties that are not directly involved in the case.
Clearly, Trump v. CASA, Inc. was monumental when it comes to discussing judicial power at an extended, nationwide scale. The decision that federal judges cannot legally issue nationwide injunctions raised concerns about the extent to which the country would be affected by arbitrary or inhumane Executive Orders and what powers were in place to prevent something unconstitutional from occurring. While supporters and dissenters of the Supreme Court’s ruling had lots to say, the true answer to this complicated question should lie in the specific situation; instead of a “one size fits all” ruling, we should adopt a legal path that allows for varying outcomes. If the Executive Order in question is truly a matter of fundamental constitutional rights, such as birthright citizenship or women’s rights, then federal judges should hold the authority to issue nationwide injunctions simply so that everyone is afforded equal protection regardless of where they live or who filed the lawsuit. If, however, it is a comparatively trivial matter, the need to issue an injunction might be unnecessary. Essentially, for this question of nationwide injunctions and their importance to be answered efficiently, the law must be able to differentiate what constitutes a need for such an injunction and what does not. To do so, Congress must establish the specific circumstances in which nationwide injunctions are appropriate to ensure that, ultimately, the rights and protections of the American people are always upheld.
