South Carolina passed an extreme anti-immigrant law in 2011. The law required police to demand “papers” demonstrating citizenship or immigration status during traffic stops when they have “reasonable suspicion” that a person is an undocumented immigrant. It also criminalized everyday interactions with undocumented immigrants. The SPLC joined a coalition of civil rights groups in filing a federal class action lawsuit challenging the law as unconstitutional. A settlement reached in 2014 blocked major provisions of the law.
