Argument to Check DHS/DOJ and the Executive Branch
ICE enforces civil immigration law and serves the civil Immigration Court system. Criminal conduct must be handled by agencies with criminal jurisdiction. ICE has no general criminal arrest authority and cannot arrest even criminal aliens for crimes; they must wait for the agency with statutory criminal authority to make the criminal arrest. ICE’s jurisdiction is limited to civil immigration enforcement involving aliens.
The Department of Justice has an obligation to investigate federal officers who act outside the authority Congress has granted. If ICE personnel engage in actions beyond their statutory civil immigration mandate, DOJ is responsible for ensuring accountability under federal law.
Congress has already defined the limits of ICE’s authority in statute, but neither Congress nor the federal courts have addressed ICE’s oversteps involving U.S. citizens because no case presenting these issues has been brought before the judiciary. Under separation‑of‑powers principles, the courts cannot interpret or constrain executive action without a live case or controversy, and Congress typically relies on judicial clarification before legislating against executive overreach. The absence of a judicial ruling therefore prevents meaningful congressional oversight, creating a structural gap in which statutory limits exist but remain unenforced.
The courts will ultimately hear these cases, and our constitutional structure will remain intact despite the appearance of crisis created by executive overreach.
