The state of Alabama is asking the U.S. Supreme Court to review part of its law cracking down on illegal immigration.
The state asked the judges Tuesday to review a section of the law that makes it a crime to assist, harbor or transport anyone who's in the country illegally.
Opponents of the law have called the section inhumane, but the state says it doesn't conflict with federal law. It also says the justices haven't reviewed a similar law in other states including Arizona.
The 11th U.S. Circuit Court of Appeals stuck down parts of Alabama's law last year, including the section that prohibits harboring illegal immigrants.
The state argues the provision is constitutional.
Opponents of the law said Wednesday they're disappointed the state is appealing.
