The U.S. Court of Appeals for the Eleventh Circuit has issued a ruling that opens the road for a class action lawsuit over traffic cameras that catch drivers running red lights.

The opinion addresses only which court will hear the case, but it shows what a litigation snarl cities can get into when they hire private companies to rev up their traffic ticket cash flow.

“We're happy with it,” plaintiffs attorney James Doyle Fuller of Fuller & Copeland in Montgomery, Alabama, said Thursday of the ruling. “I filed this lawsuit two years ago and haven't been able to take a single deposition because it's been locked up in procedural matters. At least now I can get on with my case.”
