Three Austin residents, aided by the organization behind the camping ban ordinance that is heading to voters May 1, have asked two state courts to toss out ballot language adopted by the Austin City Council, arguing it is biased and designed to elicit "no" votes. The emergency petitions, filed last week with the Texas Supreme Court and the Austin-based 3rd Court of Appeals, argued that council members violated the city charter by adopting ballot language that was different from the language presented on petitions signed by more than 20,000 registered voters. The petitions were validated Feb. 3, putting the proposed ban on camping, aggressive panhandling and loitering in certain locations before voters in the May 1 election.
