Today, the Supreme Court threw out most of Arizona's controversial immigration law.
The justices upheld a requirement that police can only question people's immigration status if an officer has a reasonable suspicion that they might be in the country illegally.
They denied a requirement that all immigrants should carry immigration registration papers, and a provision that would make it a state criminal offense for an illegal immigrant to seek work, and finally a provision that would allow police to arrest suspected illegal immigrants without a warrant.
The Supreme Court also decided that sentencing juveniles to life in prison without possibility of parole qualifies as a "cruel and unusual" punishment.
The court also ruled out the death penalty for juveniles and life without parole for children who didn't killing anyone.
This decision stems from the robbery and murder cases of Evan Miller and Kuntrell Jackson, who were both 14 when they were convicted.
This Thursday, the court will make a final decision on President Obama's health care law.
