Biden-appointed judge in Massachusetts faces new conservative backlash after blocking Trump-era immigration and vaccine policies
U.S. District Judge Brian Edward Murphy, a Biden appointee in Massachusetts, has drawn sharp conservative criticism after higher courts repeatedly stayed or overturned his injunctions halting Trump-era immigration and recent vaccine policy changes across 2025 and 2026.
- Multiple high-profile injunctions by Judge Murphy blocking immigration and vaccine policy changes have been stayed or reversed by higher courts, prompting scrutiny.
- Supreme Court and First Circuit intervention: the high court issued rare follow-up criticism and stays, and the First Circuit recently paused a Murphy order on deportations.
- Large local implications: rulings affect deportations, public-health rules, and could influence Los Angeles schools, health departments and political debates.
- Appeals pending: the Department of Justice plans continued appeals; appellate rulings will shape whether Murphy’s orders stand.
Who is Judge Brian Edward Murphy?
Background: Murphy, born in 1979 in Columbia, Maryland, was confirmed to the U.S. District Court for the District of Massachusetts in December 2024 after nomination by President Joe Biden in March 2024. He earned a B.A. from the College of the Holy Cross and a J.D. from Columbia Law School.
Before joining the bench, Murphy worked as a public defender in Massachusetts, practiced at Boston law firms, and served in nonprofit bar roles. His biography and confirmation record are on file with the Federal Judicial Center, biography of Judge Brian Edward Murphy and further profile material appears in the Vetting Room profile of Brian Murphy.
Murphy’s public defender background and work with criminal defense groups were noted favorably by Democratic senators during confirmation. Republicans pressed him on past involvement with the Massachusetts Association of Criminal Defense Lawyers, including a 2020 letter that advocated policing and arrest changes; Murphy apologized for not disclosing that earlier in his nomination questionnaire. See the Senator Ed Markey press release on Murphy nomination and the Senate Judiciary Committee release on nominee questionnaire issue.
Recent high-profile rulings and the reversals that followed
Murphy’s recent rulings have placed him at the center of disputes over the proper scope of trial-court injunctions aimed at executive-branch actions. Last year he issued an injunction against the Department of Homeland Security’s third-country deportation policy — a Trump administration priority intended to expand grounds for deportation by sending migrants to third countries — and the Supreme Court stayed that injunction in June 2025 in a 6-3 order.
A week later, the Court issued a second, sharper order that criticized Murphy for not heeding the earlier stay, an unusual step that drew attention from legal scholars. For reporting on those interventions see the Fox News reporting on Murphy’s injunctions and appeals.
On Monday, March 16, 2026, the First Circuit paused a separate Murphy order that had halted the DHS third-country deportation policy, allowing deportations to resume while appeals proceed. Court filings in the DHS litigation said Murphy’s injunction could have delayed removal of potentially thousands of migrants. The First Circuit’s action coincided with another sweeping Murphy order in a different case. (See related Fox News reporting.)
The vaccine case and the judge’s reasoning
Also on March 16, 2026, Murphy issued a broad preliminary injunction in a lawsuit brought by medical groups challenging Health and Human Services Secretary Robert F. Kennedy Jr.’s changes to Centers for Disease Control and Prevention vaccine rules. The order paused a new January 2026 child immunization schedule and invalidated a newly appointed vaccine advisory committee while litigation continues.
In his order, Murphy wrote that science is “the best we have,” quoting Carl Sagan, and emphasized the recognized public-health benefits of vaccines as part of the legal basis for the preliminary injunction. The order stopped the new schedule and suspended the committee’s decisions pending further proceedings. (See coverage: Fox News reporting.)
Conservative backlash and Department of Justice reaction
Department of Justice response: DOJ criticized Murphy’s rulings sharply. Deputy Attorney General Todd Blanche posted on X:
“How many times can Judge Murphy get reversed in one year? 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.”
That message reflects DOJ’s plan to continue appealing Murphy’s orders to higher courts.
Academic critics and conservative commentators have echoed calls for closer scrutiny of the judge’s decisions. Legal experts are divided: some view the Supreme Court’s follow-up order as a strong rebuke meant to preserve appellate hierarchy, while others contend district judges must sometimes act urgently to prevent immediate harm from potentially unlawful agency action.
What remains unclear
Public reporting documents the major interventions — two Supreme Court stays last year and the First Circuit’s pause this week — but does not present a comprehensive tally of every reversal, remand or stay in Murphy’s short tenure on the bench. Further appeals and eventual appellate decisions will determine how often and on what grounds higher courts overturn or limit his orders.

Implications for Los Angeles, California
Economic impact: Changes to federal immigration enforcement affect southern California tangibly. Los Angeles County hosts many immigrant communities and relies on immigrant labor in agriculture, construction, hospitality and care industries. A pause on deportations could temporarily limit enforcement actions, while court-authorized resumptions could increase removal proceedings and affect local resources.
Political consequences: Local politicians in Los Angeles will likely face pressure from constituents on both sides. Elected leaders prioritizing public health may welcome a court order preserving vaccine requirements; officials focused on enforcement will closely monitor federal decisions that influence detention and deportation patterns.
Social effects: Court battles over deportation and vaccine rules directly touch immigrant neighborhoods and school districts. Parents, school officials, health providers and community organizations will watch whether vaccine requirements stay in place, and whether pauses or resumptions in deportations increase fear or instability in immigrant families.
Cultural relevance: The judge’s invocation of science — including the Carl Sagan quote — resonates in communities where trust in public-health messaging is central to civic life. Stakeholders may frame Murphy’s rulings as protective of health and rights or as judicial overreach.
Practical advice for residents: Schools, clinics and county agencies should monitor appellate developments closely. Parents should watch local school district announcements about vaccine documentation and exemptions. Immigrant-serving organizations and legal-aid groups may need to prepare for shifting enforcement patterns.

Note: Murphy’s recent orders and the responses from higher courts and the Department of Justice underscore a growing flashpoint over the limits of trial-court intervention in national policy. Appeals now pending will determine whether his vaccine injunction and prior immigration rulings stand.
