SALT LAKE CITY -- Two civil rights groups are asking a federal judge to stop a Utah immigration law from taking effect next week.
The American Civil Liberties Union and the National Immigration Law Center sought an injunction Friday in federal court in Salt Lake City seeking to delay the law, which is modeled on Arizona's enforcement measure.
ACLU managing attorney Cecillia Wang says the law is unconstitutional and should not become effective until a judge can hear the case.
The ACLU and the immigration center filed a lawsuit earlier this week arguing the law violated constitutional rights to due process.
The law would require police to check the citizenship status of anyone arrested for a serious crime. It would be optional for people arrested for lesser crimes.
