Federal Judge James Patrick Hanlon ruled that Salah Sarsour presented a substantial First Amendment retaliation claim, which makes his detention unlawful. The judge found Sarsour is not a danger to the community and is not a flight risk, so he should be released. This decision reflects a growing area of litigation: whether ICE can detain legal permanent residents in removal proceedings when the underlying detention decision appears motivated by protected political speech.
What changed
Judge Hanlon ruled that Sarsour presented a substantial First Amendment retaliation claim, which makes his detention unlawful. Sarsour is a prominent Palestinian immigrant, green card holder and president of Wisconsin’s largest mosque, the Islamic Society of Milwaukee. Sarsour will reside in Wisconsin while his case continues; the judge did not issue a ruling on Sarsour’s potential deportation.
The legal claim turns on the distinction between ICE’s underlying authority to initiate removal proceedings (based on alleged non-disclosure of a foreign conviction) and the constitutional limits on detention pending that proceeding. Judge Hanlon found that even if the removal charge has legal merit, the manner and timing of the detention—coupled with evidence linking the arrest to protected speech—violates the First Amendment.
Why it matters
This ruling affects how immigration practitioners approach habeas corpus challenges to ICE custody. The decision suggests that federal courts will scrutinize whether ICE detention decisions are pretextual or retaliatory, especially when the detainee’s public advocacy on politically sensitive topics (like Israeli policy) precedes the arrest closely in time.
For practitioners, the takeaway is that a “substantial” First Amendment retaliation claim—even before full litigation on the merits—can be enough to trigger release on habeas review. You need not wait for the removal case to resolve. The judge applied a relatively plaintiff-friendly standard: asking whether there is a plausible claim of retaliation, not whether the detainee will ultimately win on that claim.
The case also reinforces that legal permanent resident status, combined with no criminal history and community ties, creates a strong presumption against detention when constitutional rights are implicated. This has practical impact on bond and release hearings in immigration courts and federal court habeas petitions.
Way forward
-
If your client is in ICE custody and engages in or has engaged in political speech on a sensitive topic: gather contemporaneous evidence (social media posts, public statements, organizational affiliations, media coverage) and document the timeline between the speech and the arrest. This timeline is critical to establishing the retaliation claim.
-
File a habeas corpus petition in federal district court, not just a bond redetermination in immigration court. The immigration judge may lack authority to reach First Amendment questions; the federal judge can, and this case shows they will hear them.
-
Brief the “substantial claim” standard. You don’t need to prove retaliation at the habeas stage—only that the detainee has raised a plausible constitutional claim. Frame it as a close temporal and contextual nexus between the protected speech and the enforcement action.
-
Verify the court’s reasoning against the government’s stated basis for the arrest. If ICE cites a technical violation of immigration law but the timing and public statements suggest political motivation, highlight that gap in your filings.
