ATLANTA (AP) — A lawsuit says a company that handles parking enforcement for the city of Atlanta knowingly cited drivers for nonexistent violations.

The suit was filed Wednesday against PARKatlanta, its parent company Duncan Solutions and associated companies.

It seeks class action status and was filed by a man who says he was issued invalid citations and by two current or former employees who say they were forced to issue citations the company knew were likely to be invalid.

The suit says the company has known for years that the wireless technology it uses can result in the mobile devices used by employees incorrectly showing someone hasn't paid for parking.

PARKatlanta's parent company, Duncan Solutions, didn't immediately return email and phone messages and a message sent through its website seeking comment Wednesday.
