On April 23, 2010, Arizona Governor Janice Brewer signed into law the Support Our Law Enforcement and Safe Neighborhoods Act of 2010 (SB 1070). SB 1070 granted law enforcement officials the authority to request identification from an individual suspected of being an undocumented immigrant, criminalized the hiring of undocumented immigrants for day labor and allowed Arizona citizens to sue the state government for failing to enforce SB 1070. In April 2011, the US Court of Appeals for the Ninth Circuit affirmed a preliminary injunction issued against the law at the request of the Department of Justice (DOJ). In June 2012, the US Supreme Court upheld the identification request provision of SB 1070 in a 5-3 opinion, but struck down other provisions of the law.
