On 14 October 2011, the Eleventh Circuit issued an injunction blocking two provisions of Alabama's immigration law (HB 56) from taking effect while the appeal proceeds, but left two other provisions in effect. The court enjoined Section 10 (making it a state crime to be undocumented in Alabama) and Section 28 (requiring public school students to prove immigration status or they will be presumed undocumented). The provisions remaining in effect are Section 30 (making it a felony for undocumented individuals to enter into business transactions with the state or a state subdivision) and Section 12 (allowing law enforcement to stop, detain, and arrest anyone suspected of being undocumented).

In September, in three cases, U.S. District Judge Sharon Blackburn (for the Northern District of Alabama) had blocked certain provisions of HB 56 from taking effect, ruling that there was a substantial likelihood the U.S. government could establish federal pre-emption. Judge Blackburn upheld other key portions of HB 56.

In addition, the U.S. Department of Justice also established a hotline for potential civil rights concerns related to the impact of HB 56 at 1-855-353-1010 or hb56@usdoj.gov.
