The law has three major sections:
- Requiring police to check the legal status of anyone they believe might be here illegally
- Making it a crime to fail to register under a federal law
- Making it a crime for undocumented migrants to work
The federal government says federal law overrules state law when the federal government has enacted similar law. However, observers said some judges indicated Arizona might be allowed to continue to stop and check an individual’s legal status. The judges’ views on the other parts of the law were not clear.
Immigrant advocates say the court will eventually have to rule on the question of whether SB1070 discriminates of the basis of race and ethnic background.
The court is expected to rule on the case in June 2012.
