When people talk about “the Supreme Court,” they usually mean finality. Black robes. Marble steps. The last word.
But most of the real governing in American law happens earlier, lower, and faster. It happens when a single district judge issues an order that takes effect immediately, long before the Supreme Court ever decides whether that order was right.
That is why Judge Brian Murphy, a Biden appointee serving on the federal district court in Massachusetts, has become a lightning rod. In recent months, his rulings have repeatedly collided with the Trump administration’s agenda, and twice drew emergency intervention from the Supreme Court in a deportation dispute. Now, after he temporarily blocked changes to federal vaccine policy in a separate case, the debate is back in full volume: What is a district court for, and how much national power should one judge be able to exercise with the stroke of a pen?
Two Fights, One Judge
Judge Murphy’s name first exploded into the national conversation over immigration, specifically the Department of Homeland Security’s “third-country” deportation policy. His orders restricting how the policy could be implemented did not just generate appeals. They triggered emergency action at the Supreme Court.
In June, the Supreme Court stayed Murphy’s injunction in a 6-3 order. Then, unusually, the Court issued a second order a week later, this one 7-2, rebuking the district court after it concluded the judge had not followed the Supreme Court’s direction the first time.
That kind of procedural escalation is rare for a reason. The Court is not built to supervise trial judges day to day. It steps in like that only when it believes the hierarchy itself is being tested.
Monday: Deportations and Vaccines
This week, Murphy drew fresh backlash after issuing a preliminary injunction in a lawsuit brought by medical organizations against Health and Human Services Secretary Robert F. Kennedy Jr. The order temporarily blocked parts of a vaccine policy overhaul, including a new immunization schedule set for January 2026.
But the timing matters. Earlier that same Monday, the U.S. Court of Appeals for the 1st Circuit paused a decision by Murphy that had blocked DHS from implementing the third-country deportation policy. That appellate stay arrived just hours before Murphy’s sweeping vaccine injunction, creating a single-day one two punch that helped fuel the political blowback.
According to the injunction, the court found it likely that the secretary’s actions violated legal requirements governing how such policy changes must be made. The order also paused a newly appointed vaccine advisory committee and treated the committee’s actions as invalid while the case proceeds.
Murphy’s opinion framed the dispute in unusually values-forward terms for an injunction order. Quoting Carl Sagan, he wrote that science is “the best we have,” and he emphasized the effectiveness of vaccines as part of his reasoning for immediate court intervention.
Why Injunctions Feel Like Governing
A preliminary injunction is not supposed to be a final verdict. It is a pause button, granted when a judge believes the challengers are likely to succeed and would suffer irreparable harm without quick relief.
But in modern American governance, the pause button often functions like a steering wheel.
Here is the structural reason: major federal policies are implemented through agencies. Those policies can be challenged immediately in federal court. And if a plaintiff persuades one judge that the policy is likely unlawful, the policy can be halted nationwide before any appellate court has fully considered the merits.
That is not inherently “activist.” It is simply the consequence of a legal system that treats courts as a check on executive action. The question is where the check becomes overbroad, especially when the underlying record is still developing.
The Criticism
Conservative critics argue that Murphy’s rulings show an ideological pattern, especially because they repeatedly disrupt core administration initiatives on immigration and public health.
Deputy Attorney General Todd Blanche put the criticism bluntly on social media after the latest injunction: “How many times can Judge Murphy get reversed in one year?” He continued, “The same day he is stayed for repeatedly refusing to follow the law, he issues another activist decision. We will keep appealing these lawless decisions, and we will keep winning.”
In context, that “same day” reference points to the 1st Circuit’s earlier stay of Murphy’s deportation ruling, not just the Supreme Court’s June actions. It is a complaint about pace and posture as much as outcomes: a higher court pauses one Murphy order, and another major injunction arrives before the legal dust settles.
Others have focused less on ideology and more on consistency. University of Minnesota law professor Ilan Wurman questioned what he described as a judicial double standard between deference to government public health experts in earlier COVID-era litigation and skepticism toward the government’s current vaccine policy shift.
Sen. Jim Banks also attacked what he sees as asymmetry, arguing that some judges who are skeptical of the new vaccine policy were not similarly skeptical of the Biden administration’s approach to sex and gender policy.
And after the Supreme Court’s second immigration-related order, constitutional law professor Jonathan Turley warned about the institutional stakes of trial courts resisting appellate control, calling it unsustainable for the judiciary as a system.
The Underlying Tension
It is tempting to treat this story as another partisan food fight: a Republican administration, a Democratic appointee, and the predictable outrage machine on both sides.
But the real tension is older than any president. It sits at the intersection of three constitutional ideas that do not always coexist peacefully.
- Judicial review: courts can say what the law is, and can stop unlawful executive action.
- Executive control of administration: presidents are elected to run the federal government and set policy through agencies.
- Judicial hierarchy: district courts are not co-equal with appellate courts or the Supreme Court.
When a district judge issues an injunction with national impact, he is exercising judicial review at its most muscular. When an appellate court or the Supreme Court stays that injunction, it is asserting hierarchy and uniformity. When a trial court appears not to conform to that stay, the system stops being a set of checks and starts looking like a set of competing commands.
What the Supreme Court Signals
Supreme Court stays are not merits decisions, but they are signals. A stay tells the public that the justices believe something is off enough to freeze a lower court’s order while the case proceeds.
Two stays in rapid succession, especially with an admonition attached, signal something sharper: the Court is not just disagreeing with a legal conclusion. It is policing the chain of command.
That matters beyond any single policy fight. If trial courts can effectively override the Supreme Court through creative phrasing or procedural maneuvering, the “one Supreme Court” model collapses into something closer to regional constitutionalism, where geography and judge assignment determine what federal law means on any given day.
What Happens Next
Murphy’s vaccine injunction is not the final word. It is the beginning of a familiar sequence: expedited appeals, emergency motions, and the real possibility that higher courts narrow or reverse the order.
Meanwhile, the immigration litigation continues to function as a cautionary tale about what happens when Supreme Court authority meets district court resistance. Whether one views Murphy as a careful check on executive power or an overreaching actor in a political storm, the institutional lesson is the same.
Our constitutional system is designed for argument. It is not designed for judges to operate as rival sovereigns.
And that is the question Americans are really debating right now, even when they think they are debating vaccines or deportations: Who gets to press pause on the federal government, and what happens when the Supreme Court presses play again?
