The U.S. Supreme Court addresses questions raised by Arizona's immigration laws. Justices expressed skepticism where the Arizona law imposes penalties and enforcement beyond what is required by Congress. At the same Justices said it was acceptable for states to do what the federal law already envisions, such as immigration officials sharing information with state police, as long as penalties and enforcement did not go beyond what Congress requires. While Justices were receptive to aspects of the law that required state police to check immigration status, they were skeptical about aspects of the law that challenge the right of illegal immigrants to seek work.
