In a pair of mixed rulings, a federal appeals court has struck down key parts of two tough immigration laws in Alabama and Georgia but upheld other controversial sections, including so-called “show me your papers” provisions. The 11th Circuit Court of Appeals struck down a provision of Alabama’s law requiring public schools to check the immigration status of students who enroll and blocked the state’s requirement that immigrants carry a registration document at all times. Judges also said the laws’ opponents were likely to succeed in challenging provisions in both states that would make it a crime under certain circumstances to knowingly transport or harbor undocumented people. But the court ruled Alabama police could continue demanding immigration documents during stops from those they suspect of being in the country illegally and paved the way for Georgia to begin enforcing a similar “show me your papers” provision. The court decisions follow a similar mixed ruling by the U.S. Supreme Court in June that overturned some parts of Arizona’s anti-immigrant law S.B. 1070, but upheld the “show me your papers” provision, which critics say legalizes racial profiling.
