The American Immigration Council and National Immigration Project of the National Lawyers Guild (NIPNLG) are seeking to preserve federal court review of damages actions brought by noncitizens for abuse of authority by immigration agents.

Long used in criminal trials, motions to suppress can lead to the exclusion of evidence obtained by the government in violation of the Fourth Amendment, Fifth Amendment, or related provisions of federal law. While the immediate purpose of filing a motion to suppress is to prevent the government from meeting its burden of proof, challenges to unlawfully obtained evidence can also deter future violations by law enforcement officers and thereby protect the rights of other noncitizens. The Supreme Court held in INS v. Lopez-Mendoza, 468 U.S. 1032 (1984), that motions to suppress evidence under the Fourth Amendment in immigration proceedings should be granted only for “egregious” violations or if violations became “widespread.” Despite this stringent standard, noncitizens have prevailed in many cases on motions to suppress.

The Council, along with the National Immigration Project of the National Lawyers Guild (NIPNLG), is seeking to preserve federal court review of damages actions brought by noncitizens for abuse of authority by immigration agents. In actions brought under Bivens v. Six Unknown Named Agents of the Federal Bureau of Narcotics, 403 U.S. 388 (1971), the government routinely moves to dismiss these cases on a variety of jurisdictional grounds, including by arguing that INA § 242(g) bars the court’s review of damages claims in any case involving removal procedures, and that a remedy under Bivens is not available in immigration-related actions. In essence, the government is attempting to deprive those who have been harmed by immigration agents of any remedy in federal court.
In March 2013, the American Immigration Council and Cleary, Gottlieb, Steen & Hamilton, later joined by the Legal Aid Justice Center, filed a lawsuit alleging that CBP officers at Dulles Airport in Virginia unlawfully detained a U.S. citizen child for more than twenty hours, deprived her of contact with her parents, and then effectively deported her to Guatemala. The case was one of ten complaints filed the same week to highlight CBP abuses along the northern and southern borders.
In June 2012, the American Immigration Council, in collaboration with Hughes Socol Piers Resnick & Dym, filed suit against DHS and CBP for unlawfully withholding records concerning voluntary returns of noncitizens from the United States to their countries of origin. Voluntary return, also known as “administrative voluntary departure,” is a procedure whereby CBP officers permit noncitizens to voluntarily depart the United States at their own expense rather than undergoing formal removal proceedings. Noncitizens may be granted voluntary return to their countries of origin after conceding unlawful presence in the United States and knowingly and voluntarily waiving the right to contest removal.
Co-Plaintiffs American Immigration Council and AILA’s Connecticut chapter initially sought records related to the Criminal Alien Program (CAP) through a FOIA request to ICE in December 2011. When ICE refused to release responsive records, Plaintiffs filed suit under FOIA to compel their disclosure.
On August 22, 2014, the American Immigration Council, in collaboration with the American Civil Liberties Union, the National Immigration Project of the National Lawyers Guild, the National Immigration Law Center, Van Der Hout Brigagliano & Nightingale LLP, and Jenner & Block, filed this lawsuit in the federal district court for the District of Columbia. The case was a systemic challenge to the policies denying a fair deportation process to mothers and children detained in the Artesia Family Residential Center who had fled extreme violence, death threats, rape, and persecution in Central America and come to the United States seeking safety.
