The court decided against hearing appeals filed by the towns of Farmers Branch, Texas, and Hazleton, Pennsylvania, which were seeking to overturn appeals court rulings that said the ordinances were trumped by federal immigration law. In doing so, the court left intact the appeals court rulings and avoided wading into the divisive issue of immigration at a time in which reform efforts have stalled in the U.S. Congress.
I have watched the Farmers Branch case closely and I believe that the 5th Circuit was right to strike down the anti-immigrant ordinance. The Supremacy Clause says that immigration law creating and regulation of immigration is the role of the federal government. Not state and local governments. I also agree that the Supreme Court was correct in agreeing with the 5th Circuit.
