The high court will hear arguments in the lawsuit challenging the bill's constitutionality. Governor Jan Brewer asked for the hearing, after a federal court upheld a decision to prevent several parts of the 2010 law from going into effect.
Brewer says the immigration issue goes beyond state borders. Also saying, "This case is just not about Arizona. It's about every state grappling with the cost of illegal immigration and it's about the fundamental principles of federalism under which every state has a right to defend its people. Despite that, the Obama administration took the audacious step of initiating a lawsuit to key provisions of the law before it ever took effect."
An injunction stopped four parts of Senate Bill 1070 from going into effect. Among them, a provision requiring police to check the immigration status of people who they suspect are in the US illegally.
Arizona had argued that illegal immigration was creating safety concerns and financial hardships across the state.
Other states have passed similar laws. Arizona's appeal is the first to reach the U-S Supreme Court.
