Judge Sharon Lovelace Blackburn, a George H.W. Bush appointee, just issued an opinion striking down parts of Alabama’s newly-enacted anti-immigrant law. Although the opinion blocks several of the law’s provisions, including the provision making it a crime for undocumented immigrants to work, the opinion leaves untouched a provision of Alabama law requiring public schools to systematically determine the immigration status of public school students and to report the number of undocumented students in their district to the state.
