Supreme Court upholds Arizona law that requires employers to check the immigration status of job applicants.

Announced, just now, on the SCOTUSblog live-blog of the Court. Here's how SCOTUSblog described the issue in the case, which is called Chamber of Commerce v. Whiting:

Whether an Arizona statute that imposes sanctions on employers who hire unauthorized aliens is invalid under a federal statute that expressly “preempt[s] any State or local law imposing civil or criminal sanctions (other than through licensing and similar laws) upon those who employ, or recruit or refer for a fee for employment, unauthorized aliens”; whether the Arizona statute, which requires all employers to participate in a federal electronic employment verification system, is preempted by a federal law that specifically makes that system voluntary; whether the Arizona statute is impliedly preempted because it undermines the “comprehensive scheme” that Congress created to regulate the employment of aliens.

According to the live-blog, the decision was 5-3 (with Kagan recused). Breyer, Ginsburg, and Sotomayor are the dissenters.

The Chief Justice's opinion explains that the licensing provision falls squarely within a savings clause in federal immigration law and that the Arizona statute does not otherwise conflict with federal law.

Here's the PDF of the opinion.
