On May 17, 2010, the American Civil Liberties Union (ACLU) filed a class action lawsuit in the US District Court for the District of Arizona seeking an injunction against the implementation of Arizona's immigration reforms. The lawsuit challenged the constitutionality of the immigration law, claiming that it violated the Supremacy Clause of the Constitution as well as the First, Fourth, and Fourteenth Amendments. SB 1070 was signed into law by Arizona Governor Jan Brewer in April 2010. It requires law enforcement officers to verify the immigration status of all "suspected individuals" and criminalized the hiring of illegal immigrants for day labor. The court later enjoined several provisions of Arizona's immigration law at the request of the US Department of Justice (DOJ).
