In May 2011, the ACLU filed suit in U.S. District Court challenging the Utah law, claiming that it unlawfully interferes with the federal government’s sole authority over immigration matters; that the “show me your papers” provision violates the Fourth Amendment ban against unreasonable search and seizure; and that it violates the constitutional right to travel freely throughout the United States.
The District Court temporarily blocked major provisions of the discriminatory law from going into effect pending further deliberation. Several prominent law enforcement officials in Utah, including the Salt Lake City Police Chief, opposed the law because it undermines cooperation between local police and immigrant communities.
In June, 2014 the District Court issued its ruling striking down key provisions of the law, including those that allow for warrantless arrest based solely on suspicion of immigration status and the harboring provision that made it a crime to assist undocumented immigrants in everyday activities like driving them to work. The court also put strict limits on the “show me your papers” provision, ruling that it does not authorize police to stop or detain an individual simply to verify his or her immigration status.
