Florence Immigrant & Refugee Rights Project v. Mayes

The American Civil Liberties Union and ACLU of Arizona filed a federal lawsuit on behalf of the Florence Immigrant & Refugee Rights Project challenging Section 5, a previously deferred provision of Proposition 314 that would unconstitutionally usurp federal immigration enforcement power by making it a state crime for some immigrants to enter or remain in Arizona. Courts across the country have repeatedly reaffirmed that immigration enforcement is a power that belongs exclusively to the federal government — not the states.
