A federal judge on Tuesday dismissed one of the seven lawsuits that seek to overturn Arizona's new immigration law.
U.S. District Judge Susan Bolton says the lawsuit by Washington-based researcher Roberto Frisancho didn't allege an injury that was concrete and not based on speculation.
Frisancho alleged that as U.S.-born Hispanic he would likely be asked during an upcoming research trip to Arizona for immigration papers based on a suspicion that he's in the country illegally.
Gov. Jan Brewer and Attorney General Terry Goddard sought the dismissal of Frisancho's lawsuit.
Last month, Bolton put the law's most controversial elements on hold in a case filed by the U.S. Justice Department.
The other six lawsuits remain alive.
