On January 27, 2011, the Arizona House of Representatives and Senate introduced bills challenging the right to US citizenship for the children of legal and illegal immigrants born in the state. By introducing revisions to Title 36, Chapter 3 of the Arizona Revised Statutes, the legislature sought a review of the US Constitution's Fourteenth Amendment guarantee of citizenship to, "all persons born or naturalized in the United States, and subject to the jurisdiction thereof." Because the bills have yet to be voted on, public attention has shifted to Arizona's SB 1070, which would allow law enforcement officers to check the immigration status of anyone they detain and requires immigrants to carry papers at all times. The controversial measure passed the Arizona Senate in April 2010, but has faced recent legal challenges. The US Supreme Court granted certiorari in December 2011 and the case is scheduled for review by April 2012.
