The twisted logic of Arizona court decision
...The Ninth circuit is not known for getting things right so this may have to go the the US Supreme Court before justice can be served. It is clear it was not served by this decision.
In essence, Judge Susan Bolton bought the Justice Department's preemption argument — i.e., the claim that the federal government has broad and exclusive authority to regulate immigration, and therefore that any state measure that is inconsistent with federal law is invalid. The Arizona law is completely consistent with federal law. The judge, however, twisted to (sic the) concept of federal law into federal enforcement practices (or, as it happens, lack thereof). In effect, the court is saying that if the feds refuse to enforce the law the states can't do it either because doing so would transgress the federal policy of non-enforcement ... which is nuts.
The judge also employs a cute bit of sleight-of-hand. She repeatedly invokes a 1941 case, Hines v. Davidowitz, in which the Supreme Court struck down a state alien-registration statute. In Hines, the high court reasoned that the federal government had traditionally followed a policy of not treating aliens as "a thing apart," and that Congress had therefore "manifested a purpose ... to protect the liberties of law-abiding aliens through one uniform national system" that would not unduly subject them to "inquisitorial practices and police surveillance." But the Arizona law is not directed at law-abiding aliens in order to identify them as foreigners and subject them, on that basis, to police attention. It is directed at arrested aliens who are in custody because they have violated the law. And it is not requiring them to register with the state; it is requiring proof that they have properly registered with the federal government — something a sensible federal government would want to encourage.
Judge Bolton proceeds from this misapplication of Hines to the absurd conclusion that Arizona can't ask the federal government for verification of the immigration status of arrestees — even though federal law prohibits the said arrestees from being in the country unless they have legal status — because that would tremendously burden the feds, which in turn would make the arrestees wait while their status is being checked, which would result in the alien arrestees being treated like "a thing apart."
The ruling ignores that, in the much later case of Plyler v. Doe (1982), the Supreme Court has emphasized that
Although the State has no direct interest in controlling entry into this country, that interest being one reserved by the Constitution to the Federal Government, unchecked unlawful migration might impair the State's economy generally, or the State's ability to provide some important service. Despite the exclusive federal control of this Nation's borders, we cannot conclude that the States are without power to deter the influx of persons entering the United States against federal law, and whose numbers might have a discernible impact on traditional state concerns. [Emphasis added.]
Furthermore, as Matt Mayer of the Heritage Foundation notes, the Fifth Circuit federal appeals court similarly held in Lynch v. Cannatella (1987) that "No statute precludes other federal, state, or local law enforcement agencies from taking other action to enforce this nation's immigration laws."
