Chicago cell phone users fighting to fend off a city ordinance that bars them from driving and chatting on their phone without a hands-free device have lost another round.

The 7th U.S. Circuit Court of Appeals in a decision Thursday (pdf) agreed with the U.S. District Court for the Northern District of Illinois that the class action mounting a constitutional challenge to the 2005 city law “has no legs.” And by the way, that law also precludes texting and surfing the Internet while driving, the court noted.
