Overview

When evaluating Immigration and Customs Enforcement (ICE) conduct, courts and commentators most often look to a cluster of constitutional amendments that govern searches, seizures, detention, due process, speech, and equal protection. Below is a clear, issue-by-issue breakdown of the amendments most commonly implicated by U.S. Immigration and Customs Enforcement activities.

2. Fifth Amendment — Due Process (Federal Government)

Core Protection: No deprivation of liberty without due process of law.

Common ICE Issues

• Prolonged detention without bond hearings
• Inadequate notice of charges or proceedings
• Coerced statements during questioning
• Detention conditions that are punitive rather than civil

Key Legal Principles

• Non-citizens (including undocumented individuals) are entitled to due process
• Civil detention must be reasonably related to immigration purposes

2025–2026 Developments

• Alien Enemies Act Invocations (2025): The Trump administration invoked the 1798 Alien Enemies Act (AEA) in March 2025 to deport Venezuelan nationals alleged to be members of the Tren de Aragua gang — bypassing normal immigration court proceedings. Individuals were flown to El Salvador’s CECOT prison. A district court TRO ordering planes to turn around was defied, triggering contempt proceedings.
• **Supreme Court Reaffirms Due Process (Trump v. J.G.G., April 7, 2025):** The Supreme Court unanimously reaffirmed that non-citizens subject to AEA removal have a Fifth Amendment due process right to a meaningful opportunity to challenge their detention and removal before it occurs. The Court differed on procedural specifics but was unanimous that due process applies regardless of immigration status.
• ***Orellana Castaneda v. DHS* (S.D.N.Y., 2025):** In a case against Suffolk County, the court held on January 2, 2025 summary judgment that ICE detainers are civil, not criminal, instruments — and that detaining individuals solely on a detainer without independent probable-cause review is an unconstitutional seizure. A November 12, 2025 final judgment awarded substantial damages. The ruling amplifies financial liability risk for localities that honor detainers without statutory authority.
• **ICE Detainer Probable Cause Requirements (Gonzalez v. ICE, Ninth Circuit):** The Ninth Circuit required neutral-decisionmaker review before continued detention on an ICE detainer, and scrutinized the reliability of government databases used to establish probable cause — binding within the Ninth Circuit and persuasive nationally.
• Rapid Deportation Concerns: Legal advocates documented the administration rushing removals, limiting immigration judge authority, and removing individuals before meaningful consultation with counsel — all challenged as Fifth Amendment violations in pending litigation.
• Post-Shooting “Illegal Alien” Characterizations Without Adjudication (July 2026): After the fatal Biddeford ICE shooting of Joan Sebastian Guerrero, DHS characterized him as an “illegal alien” and asserted that “work authorization does not confer legal status,” while providing no case-specific evidence about his immigration status. Greg Chen of the American Immigration Lawyers Association (AILA) countered that many people with work permits are pending-asylum applicants — eligible for work authorization under 8 C.F.R. § 208.7 once an asylum application has been pending 180 days — and are lawfully present and protected from removal while their case is pending. The pattern of DHS pronouncing legal status post-mortem, without adjudication, undercuts the Fifth Amendment premise that status determinations require process; it also complicates any subsequent civil-rights or Bivens-type claim by shifting the narrative before an independent record can be developed.

3. Sixth Amendment — Criminal Procedure Rights

Core Protection: Rights in criminal prosecutions (counsel, speedy trial, confrontation).

Common ICE Issues

• When immigration enforcement transitions into criminal prosecution (e.g., illegal reentry)
• Questioning that implicates the right to counsel
• Statements obtained without proper advisement once criminal charges attach

Important Limitation

• Most immigration proceedings are civil, so Sixth Amendment rights apply only when criminal charges are involved

4. First Amendment — Speech, Association & Religion

Core Protection: Freedom of speech, assembly, religion, and press.

Common ICE Issues

• Surveillance of protests or advocacy groups
• Enforcement actions allegedly motivated by speech or political activity
• Religious-based profiling or interference with worship

Key Legal Principle

• ICE enforcement cannot be retaliatory based on protected expression or beliefs

2025–2026 Developments

• Courthouse Arrest Program (2025–2026): Beginning in mid-2025, ICE began systematically arresting immigrants inside and near courthouses — including immigration courts — creating chilling effects on immigrants’ willingness to appear for hearings, seek legal assistance, or cooperate with law enforcement.
• DOJ Admission (March 2026): In litigation before Judge Kevin Castel (S.D.N.Y.), the DOJ admitted that the May 2025 ICE memo used to justify courthouse arrests did not apply to immigration courts — meaning months of courthouse arrests had been based on an erroneous legal interpretation. The ACLU called this “another example of ICE’s brazen disregard for the lives of immigrants.”
• Federal Injunction: A federal court temporarily blocked ICE arrests inside New York City immigration courts following the government’s admission, finding the practice chilled the exercise of legal rights.
• ***Philadelphia Yearly Meeting v. DHS* (2025–2026):** A coalition of religious groups sued the Trump administration after DHS lifted longstanding “sensitive locations” policies that had protected houses of worship from immigration enforcement. District courts issued TROs blocking enforcement at houses of worship; the case is on appeal to the Fourth Circuit. The litigation raises both First Amendment free exercise claims and Fifth Amendment due process arguments.
