What Was the Purpose of Arizona's Immigration Bill, S.B. 1070?


Quick Answer

Signed into law in 2010, Arizona's legislative bill S.B. 1070, the Support Our Law Enforcement and Safe Neighborhoods Act, codified several provisions relating to immigration issues in the state, explains the National Conference of State Legislatures.

S.B. 1070's other provisions included making it a state crime for authorized aliens to not carry federal alien registration papers; prohibiting unauthorized aliens from performing, soliciting or applying for work; and allowing the warrantless arrest of individuals for whom there is probable cause that they have committed a crime punishable by deportation, according to the NCSL.

In 2012, the U.S. Supreme Court struck down these three provisions under the Constitution's Supremacy Clause, notes the NCSL. The Court determined these issues were governed by pre-existing federal laws that superseded the state laws, rendering the state laws unconstitutional. When S.B. 1070 was enacted, Arizona's governor also enacted an executive order requiring special training to ensure state law enforcement officers applied S.B. 1070's provisions in accordance with federal laws, and in a way that protected the civil rights of those affected.
