Bolton temporarily blocked the section requiring police to "make a reasonable attempt to determine the immigration status of a person stopped, detained or arrested" -- which critics said would lead to racial profiling.
She also blocked a section making it "a crime (if an immigrant fails) to apply for or carry alien registration papers" -- which critics said would
lead to innocent U.S. citizens being jailed as illegal aliens -- and making it "a crime for an unauthorized alien to solicit, apply for or perform
work."
Bolton said "the United States is likely to suffer irreparable harm if the court does not preliminarily enjoin enforcement of these sections ... "
She left in place provisions of the law she said did not pre-empt U.S. law -- and therefore were unaffected by the supremacy clause -- and those
sections that were not challenged by the Justice Department.
Bolton said her court "by no means disregards Arizona's interests in controlling illegal immigration and addressing the concurrent problems with crime including the trafficking of humans, drugs, guns, and money. Even though Arizona's interests may be consistent with those of the federal government, it is not in the public interest for Arizona to enforce pre-empted laws."
