PHOENIX — A federal judge, ruling on a clash between the federal government and a state over immigration policy, has blocked the most controversial parts of Arizona’s immigration enforcement law from going into effect.
In a ruling on a law that has rocked politics coast to coast and thrown a spotlight on the border state’s fierce debate over immigration, United States District Court Judge Susan Bolton in Phoenix said some aspects of the law can go into effect as scheduled on Thursday.
The parts of the law that the judge blocked included the sections that called for officers to check a person’s immigration status while enforcing other laws and that required immigrants to carry their papers at all times. Judge Bolton put those sections on hold until the issues are resolved by the courts.
The judge’s decision, which came as demonstrators opposed and supporting the law gathered here and after three hearings in the past two weeks in which she peppered lawyers on both sides with skeptical questions, seemed unlikely to quell the debate.
