The Supreme Court on September 8, 2025, allowed the resumption of federal immigration stops in Los Angeles based solely on appearance, language, occupation, or location, granting a request from the Trump administration in a 6-3 unsigned order that immediately paused a lower court’s injunction. The decision, which drew a sharp dissent, means federal agents can again conduct “roving patrols” and detain people without reasonable suspicion—an abrupt change that civil rights advocates say will expose millions of Latinos and other minorities to racial profiling and sudden detentions during routine parts of daily life.
The ruling’s reach is both simple and sweeping: it permits immigration stops triggered by what someone looks like, how they speak, where they are found, or the kind of job they perform, without any other basis.

Key details of the Supreme Court order
- Order date: September 8, 2025
- Vote/format: 6-3, unsigned order; stayed a lower-court injunction and allowed enforcement to resume immediately.
- Effects: Federal agents in Los Angeles may resume immigration stops and detentions based solely on appearance, language, occupation, or location.
- Majority posture: No full opinion explaining the rationale.
- Justice Kavanaugh concurrence: Suggested that ethnicity and related factors may be “relevant” indicators in immigration stops and acknowledged that U.S. citizens and lawful residents might be detained but said they “will be free to go after the brief encounter.”
- Dissent: Justice Sonia Sotomayor, joined by Justices Elena Kagan and Ketanji Brown Jackson, called the ruling “unconscionably irreconcilable with our nation’s constitutional guarantees,” warning it will green‑light mass detentions based on skin color, language, or job type.
- Case name & next step: Vasquez Perdomo v. Noem; a federal district court hearing is set for September 24, 2025, to consider a preliminary injunction based on additional evidence.
The immediate legal effect is temporary: the Supreme Court’s order stays the lower court injunction for now, but the underlying case continues and may return to higher courts depending on the district court and appeals.
Legal context and constitutional concerns
- The lower court (U.S. District Judge Maame Ewusi‑Mensah Frimpong) had halted the enforcement practices after concluding the June raids were likely unconstitutional under the Fourth Amendment’s protection against unreasonable seizures.
- With the injunction paused, those protections are not currently enforced, and agents have broad latitude to resume practices the lower court found likely violated constitutional protections.
- Critics say the order collapses decades of judicial protections requiring individualized reasonable suspicion before stops and amounts to legalized profiling.
- Supporters argue federal immigration enforcement involves unique interests that may justify different thresholds in certain contexts, especially in dense urban areas or industry-targeted operations.
On-the-ground effects in Los Angeles
- Where stops may occur: Car washes, tow yards, farms, parks, bus stops, job sites, and other public places “known to gather” immigrants.
- Who faces higher risk: Latinos and other minorities, including U.S. citizens, lawful residents, and undocumented immigrants; workers in landscaping, agriculture, construction, and day labor.
- Practical consequences:
- Stops may occur quickly and without explanation.
- People may be detained without immediate access to counsel or a clear statement of reasons.
- Short detentions can cause missed shifts, lost wages, child care gaps, and emotional trauma.
- Families may avoid schools, clinics, parks, or public transit hubs out of fear.
- Community impact: Employers, schools, and health providers may see absenteeism, staffing shortages, and degraded trust in public institutions.
Voices from the community and advocacy groups
- Annie Lai (UC Irvine School of Law): Called the ruling “a devastating blow to communities reeling from the government’s racially discriminatory raids.”
- Teresa Romero (United Farm Workers): Warned the ruling puts farm workers—and “every Californian who looks or sounds like they might be an immigrant”—in greater danger.
- Armando Gudino (Los Angeles Worker Center Network): Said the order “legitimizes the unconstitutional practice of targeting individuals based on their race, language, or neighborhood.”
- Civil rights groups: The ACLU of Southern California and local worker centers are mobilizing hotlines, town halls, know‑your‑rights trainings, and legal aid.
What supporters of the policy say
- The Trump administration and some DHS officials argue that:
- These tools are necessary to enforce federal law in areas with high levels of undocumented immigration.
- Appearance, language, occupation, and location can be useful signals in dense urban enforcement campaigns.
- Agents need latitude to act where status is hard to assess on the spot.
- Analysis cited by proponents (e.g., VisaVerge.com) suggests the administration’s legal theory treats immigration enforcement as involving unique federal interests that can justify a different threshold for brief stops than ordinary policing.
Civil liberties and practical risks highlighted by opponents
- Opponents argue Los Angeles is not a border, and constitutional protections apply equally inside the country regardless of background or language.
- Risks include:
- Normalizing a blurred line between immigration enforcement and local policing.
- Data‑collection errors and snap decisions leading to wrongful detentions that can take hours or days to resolve.
- Long‑term erosion of community trust and civic participation (e.g., keeping children home, avoiding clinics).
- Justice Sotomayor’s dissent warned the ruling opens the door to mass detentions “based on skin color, language, or occupation.”
The legal road ahead — timeline and possible outcomes
- District court hearing on September 24, 2025 to consider a preliminary injunction.
- Possible outcomes:
- If the district court grants an injunction and the Ninth Circuit upholds it, the administration can seek another stay from the Supreme Court.
- If the injunction is denied, enforcement under the four‑factor framework may continue until further appeals.
- Either result is likely to be appealed, potentially returning the issue to the Supreme Court for a full ruling that could set national precedent.
Community response and preparations
- Advocacy groups and organizers plan to:
- Collect declarations and evidence from people stopped under the revived policy.
- Track locations and patterns of stops for presentation at the September 24 hearing.
- Continue public demonstrations, hotlines, and know‑your‑rights trainings.
- Public defenders and legal aid organizations are preparing for a likely rise in calls and detentions.
- Local leaders and police departments are discussing roles and coordination with federal agents; concerns persist about blurred lines between local policing and federal immigration enforcement.
Practical advice and resources
- Keep contact numbers for attorneys and family; know local hotlines run by community groups.
- If detained, seek legal help as soon as possible and document the encounter afterward.
- For official federal statements and updates, check the Department of Homeland Security at Department of Homeland Security.
Broader implications
- If the Court ultimately endorses stops based solely on appearance, language, location, and occupation, other cities may see similar operations.
- If the Court rejects that approach later, it could reaffirm the reasonable‑suspicion standard and rein in what opponents call dragnet tactics.
- Meanwhile, millions of Angelenos face daily choices shaped by heightened uncertainty about routine activities—where to work, how to commute, and how to go about family life without risking detention.
The Supreme Court’s order is a legal event with immediate, lived consequences: it affects a landscaper heading to a job site, a farm worker leaving a shift, a student speaking Spanish on campus, or any resident who might be perceived as an immigrant. Until the courts fully resolve the case, stops tied only to appearance or language will shape everyday life in Los Angeles.
This Article in a Nutshell
The Supreme Court on September 8, 2025 issued a 6-3 unsigned order staying a lower-court injunction and allowing federal immigration stops in Los Angeles based solely on appearance, language, occupation, or location. The order permits roving patrols and brief detentions without the individualized reasonable suspicion the district court had found likely required under the Fourth Amendment. Justice Kavanaugh’s concurrence indicated ethnicity-related factors might be relevant; Justice Sotomayor’s dissent warned the ruling could green-light mass detentions and racial profiling. A federal district hearing in Vasquez Perdomo v. Noem is scheduled for September 24, 2025 to consider a preliminary injunction. Civil-rights groups, worker centers, legal-aid organizations and community leaders are mobilizing to document stops, provide know-your-rights training and prepare legal responses while supporters defend the measures as necessary for immigration enforcement in dense urban or industry-targeted contexts.
