One of the latest attempts by a civil rights coalition to bar police from enforcing the most contentious part of Arizona’s immigration law has failed.

The Wednesday ruling by U.S. District Susan Bolton comes a day after she ruled police can immediately start enforcing a requirement that officers, while enforcing other laws, question the immigration status of those suspected of being in the country illegally.

The ruling on Wednesday denied the coalition’s request to bar enforcement of the requirement while it appeals Bolton’s Sept. 5 ruling that sunk the coalition’s bid to block the provision.

The coalition has a similar request before the 9th Circuit Court of Appeals.

The appeals court has yet to rule on the coalition’s request.
