On April 11, 2011, the US Court of Appeals for the Ninth Circuit upheld a lower court decision to enjoin several provisions of a controversial Arizona immigration law. This reaffirmed the decision of the US District Court for the District of Arizona that granted a preliminary injunction against enforcement of the laws sought by the Department of Justice (DOJ). The dispute arose after the DOJ sued the state of Arizona in 2010, arguing that the Constitution does not permit arbitrary state and local immigration policies that vary across the country. The legislation in question was signed into law in April 2010 by Arizona Governor Jan Brewer. It requires Arizona police officers to validate any person's immigration status if there is reasonable suspicion that the person is in the US illegally. The ACLU previously filed a challenge to the law in May 2010 based on the claim that it would lead to racial profiling, but the challenge was dismissed in September 2009.
