The U.S. Supreme Court agreed today to rule on Arizona's controversial law targeting illegal immigrants, according to press reports. This move follows a federal appeals court's refusal to lift a stay that prevents major parts of the law from taking effect. In August, Arizona Gov. Jan Brewer requested that the court lift an injunction imposed by a federal judge in Phoenix the day before the law was to take effect on July 29, 2010. Among the parts of SB 1070 that the federal court blocked is the section that requires an officer to make a reasonable attempt to determine the immigration status of people who are stopped, detained or arrested if there's reasonable suspicion they're in the country illegally. Also blocked was the section that requires immigrants to carry their papers with them at all times.
