Biden judicial appointee Judge Brian Murphy draws fresh conservative fire after blocking Trump deportation and vaccine policies
U.S. District Judge Brian Edward Murphy, a Biden appointee in Massachusetts, has faced repeated reversals — including rare Supreme Court admonitions — after issuing injunctions blocking a Trump-era deportation policy and changes to the CDC child immunization schedule.
- Nomination and commission: See the Federal Judicial Center biography for nomination (March 21, 2024), Senate confirmation (Dec. 2, 2024) and commission (Dec. 6, 2024).
- High-profile injunctions: Murphy issued orders blocking the third-country deportation policy and a January 2026 CDC immunization schedule; both actions prompted rapid appeals and stays — see Fox News reporting on Murphy’s rulings.
- Supreme Court intervention: The high court stayed Murphy’s first deportation injunction on June 23, 2025 (6–3) and later issued a rare follow-up order admonishing enforcement after the stay (7–2) — Fox News reporting.
- March 16, 2026 developments: The 1st Circuit paused a new Murphy order the same day Murphy issued a sweeping injunction blocking CDC immunization changes — see Fox News reporting.
Background: Who is Judge Brian Murphy?
Brian Edward Murphy was born in 1979 in Columbia, Maryland. He served as a public defender from 2006 to 2009 and later practiced privately in Boston and Worcester before elevation to the federal bench. For a full professional biography, see the Federal Judicial Center biography.
Nomination and confirmation: Murphy was nominated by President Biden on March 21, 2024 and confirmed by the Senate on Dec. 2, 2024; he received his commission on Dec. 6, 2024. Senators Ed Markey and Elizabeth Warren publicly praised his public defender work and commitment to constitutional rights — see the Markey–Warren statement.
Confirmation controversies: Republicans scrutinized Murphy for prior involvement with the Massachusetts Association of Criminal Defense Lawyers and for a 2020 letter advocating reduced arrests for certain offenses. Murphy later apologized for omissions in his questionnaire related to that matter — see reporting at Vetting Room and the Senate Judiciary release.
The deportation case: third‑country policy and multiple stays
April 18, 2025 injunction: Murphy issued a nationwide preliminary injunction blocking the Department of Homeland Security’s third‑country deportation policy, finding due‑process concerns and risks that migrants sent to third countries could lack meaningful protection from torture or persecution. Coverage and analysis appear in Fox News reporting.
Supreme Court stays and admonitions: On June 23, 2025 the Supreme Court stayed Murphy’s injunction in a 6–3 order. Weeks later the Court issued a rare follow‑up 7–2 order after Murphy issued a remedial order directing six migrants to be sent to South Sudan despite the stay; the justices admonished the judge that the initial injunction was fully stayed and must not be enforced.
March 2026 ruling and appeals: In March 2026 Murphy issued an 81‑page ruling again blocking the third‑country policy on due‑process grounds related to migrants’ ability to show fear of torture in third countries. The order was stayed for 15 days and then paused by the U.S. Court of Appeals for the 1st Circuit on March 16, 2026, prompting another round of appeals. Repeated interventions have at times prevented DHS from carrying out deportations affecting what court filings said could be thousands of migrants.
Vaccine case: blocking CDC immunization changes
March 16, 2026 injunction: On the same day the 1st Circuit paused the deportation order, Judge Murphy granted a sweeping preliminary injunction in litigation brought by several medical organizations against Health and Human Services Secretary Robert F. Kennedy Jr., blocking a January 2026 CDC immunization schedule that reduced the number of child vaccine requirements.
Scope of the order: Murphy’s injunction temporarily invalidated a newly appointed vaccine advisory committee and its decisions while the litigation proceeds, halting immediate implementation of the CDC’s new schedule over claims that the changes violated administrative rules and risked public health. Murphy quoted Carl Sagan — calling science “the best we have” — and emphasized vaccine efficacy in explaining the preliminary relief. Reporting: Fox News reporting.
Criticism, appeals and the DOJ response
Deputy Attorney General Todd Blanche posted on X criticizing Murphy’s decisions: “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.”
Appeals strategy: The Department of Justice quickly signaled it would appeal both the vaccine injunction and the March deportation ruling, signaling an aggressive appellate approach. Conservative commentators and some Republican lawmakers labeled Murphy an activist judge exceeding his authority, while supporters argue he is checking executive actions that may violate statutory or constitutional safeguards.
The record in context
Murphy has served less than two years on the bench. His national profile stems from two high‑stakes policy fights that directly affect Trump administration priorities: immigration enforcement and vaccine policy. Rapid appellate movement — including two rare Supreme Court orders in 2025 and an immediate 1st Circuit stay in 2026 — has amplified scrutiny and highlighted how quickly district‑court rulings can influence national policy.
Implications for the world
- Legal and political ripple effects: U.S. immigration rulings affect regional migration flows, asylum cooperation, and relations with potential receiving countries. Repeated stops and starts create uncertainty for governments and NGOs coordinating refugee protection — reporting and context in Fox News reporting.
- Public health and global confidence: Blocking CDC immunization changes may influence international health bodies and vaccine policy makers who look to U.S. agencies for guidance; legal fights can slow harmonization of child immunization norms and raise questions about U.S. processes.
- Judicial precedent and transnational litigation: Outcomes from higher courts could shape standards for administrative procedure and due process that other nations reference when reforming rules; see the Federal Judicial Center biography for background.
- Political optics: The cycle of injunctions and reversals may feed perceptions abroad about political polarization in U.S. institutions and could affect how stable U.S. governance appears to moderate international audiences.
- Practical effects: Freezes on deportations provide temporary relief for migrants and time for appeals; blocked CDC changes keep the status quo for vaccination requirements, affecting schools, clinics and global partners coordinating with U.S. guidance.
