US court reconsiders ruling on Arizona voter law...The latest court battle between AZ and the federal government is being fought in a Pasadena, CA courtroom where an appeals court will hear arguments TODAY on whether the state can require proof of citizenship to register to vote. An 11-judge panel of the 9th U.S. Circuit Court of Appeals is reconsidering a three-judge panel’s ruling that the state’s proof of citizenship requirement conflicts with federal voter registration law that law allows people registering to vote to swear under penalty of perjury that they are citizens. AZ’s law goes further, requiring that people registering show proof of citizenship. It was part of a ballot measure approved by voters in 2004.
