The four enjoined provisions direct state law-enforcement officers to cooperate and communicate with federal officials regarding the enforcement of federal immigration law and impose penalties under state law for non-compliance with federal immigration requirements.
The four provisions in question are as follows:
- The requirement that police when making a stop to attempt to determine an individual’s immigration status should an officer have a “reasonable suspicion” that the individual is in the United States in violation of immigration laws. If arrested, an individual is precluded from release until immigration status is verified by the federal government.
- A provision requiring that criminalizes the act of intentionally failing to obtain and carry proof of lawful immigration status while in Arizona.
- The inclusion of a misdemeanor offense for the act of applying for employment, publicly soliciting employment, or working in Arizona without authorization.
- Permission for a probable cause warrantless arrest of any person should a police officer reasonably believe that the individual has committed any crime, anywhere, that would subject them to removal from the United States.
