US Attorney Bill Nettles said today the government wants a judge to stop enforcement of the legislation. The law requires that officers call federal immigration officials if they suspect someone is in the country illegally following a traffic stop for something else. Nettles said the law is unconstitutional and violates people's right to due process. South Carolina's law takes effect Jan. 1 and is among the toughest in the nation, requiring police to determine immigration status during any unlawful stop where officers have "reasonable suspicion" of a suspect's immigration status. The US Justice Department is challenging similar laws in Arizona and Alabama. A spokesman for South Carolina Attorney General Alan Wilson said the state had not received a copy of the lawsuit.
