The U.S. Supreme Court landed the final blow against an Arizona law that denied bail to immigrants who are in the country illegally and are charged with certain felonies, marking the latest in a series of state immigration policies that have since been thrown out by the courts.

The nation's highest court on Monday rejected a bid from metro Phoenix's top prosecutor and sheriff to reinstate the 2006 law after a lower appeals court concluded late last year that it violated civil rights by imposing punishment before trial.

While a small number of Arizona's immigration laws have been upheld, the courts have slowly dismantled most of the other statutes that sought to draw local police into immigration enforcement.

"At this point, we can say that was a failed experiment," said Cecillia Wang, an attorney for the American Civil Liberties Union who led the challenge of the law. "Like the rest of the country, Arizona should move on from that failed experiment."

Voters overwhelmingly approved the no-bail law as the state's politicians were feeling pressure to take action on illegal immigration. It automatically denied bail to immigrants charged with a range of felonies that included shoplifting, aggravated identity theft, sexual assault and murder.
