The Supreme Court agreed on Monday to hear a case next term concerning Kansas' prosecution of three undocumented immigrants for using stolen Social Security numbers in an effort to gain employment.Those convictions were overturned when the Kansas Supreme Court ruled that the federal immigration law at issue preempts a state from prosecuting undocumented immigrants, when the basis of the claim comes from information that has been culled from federal immigration forms.The case raises the question about the extent to which federal immigration law preempts states from also trying to enforce immigration law.
