A forthcoming U.S. Supreme Court decision on Arizona’s controversial immigration law — which some experts believe could uphold the most controversial aspects of the measure — won’t end legal disputes on the matter and instead is likely to ignite renewed assaults by the law’s opponents.

The court is evaluating the 2010 law on only the question of whether Arizona’s attempt to fix its border problems is trumped by federal law. That means that opponents could still ask the courts to block enforcement of the law on other legal grounds.

For example, the high court isn’t considering the possibility that racial profiling may arise from the law — because the Obama administration’s lawsuit didn’t challenge it on those grounds. The administration focused instead on whether federal law supersedes the state law, an issue known as “pre-emption.”
