Civil rights groups have asked a federal judge to delay Arizona authorities from enforcing the most contentious section of the state's immigration law, SB 1070.

A Sept. 5 ruling by a federal judge in Phoenix cleared the way for police to carry out the requirement that officers question the immigration status of those they suspect are in the country illegally while officers are in the act of enforcing other laws.

Civil rights, religious and business groups Thursday filed an emergency motion for an injunction pending appeal.

The "stop and check" requirement was upheld by the U.S. Supreme Court in June, in an opinion that said three other provisions were unconstitutional.
