Ruling Against Arizona Is a Warning for Other States

New York Times: A federal judge in Arizona on Wednesday broadly vindicated the Obama administration’s high-stakes move to challenge that state’s tough immigration law and to assert the primary authority of the federal government over state lawmakers in immigration matters. The ruling by Judge Susan R. Bolton, in a lawsuit against Arizona brought on July 6 by the Justice Department, blocked central provisions of the law from taking effect while she finishes hearing the case. But in taking the forceful step of holding up a statute even before it was put into practice, Judge Bolton previewed her opinions on the case, indicating that the federal government was likely to win in the end on the main points.
