WASHINGTON (Reuters) - The U.S. Supreme Court on Monday upheld the main provision of Arizona's crackdown on illegal immigrants but threw out three other parts, handing partial victories to President Barack Obama in his challenge to the law and to the measure's conservative supporters.
In an important test of whether federal or state governments have the power to enforce immigration laws, the top U.S. court unanimously upheld the statute's most controversial aspect, a requirement that police officers check the immigration status of people they stop, even for minor offenses such as jay-walking.
