A coalition of civil rights and immigrant rights groups has appealed a federal judge’s ruling upholding key portions of Alabama’s controversial immigration law. This week, Chief U.S. District Judge Sharon Lovelace Blackburn backed provisions that would require police to arrest anyone they suspect of being in the country without legal status, prevent courts from enforcing contracts involving undocumented immigrants, and allow public schools to determine the immigration status of enrolled students. The appeal is led by the Hispanic Interest Coalition of Alabama, which is seeking an injunction to block the law’s provisions from taking effect while they are under review.
