CHICAGO (WLS) -- The legal challenge of Chicago's red light cameras is moving forward despite the objections of city lawyers.
A Cook County Judge threw out a bid from the City of Chicago to shut down a proposed class-action lawsuit over the city's red light cameras.
A small group gathered outside Daley Plaza protesting the controversial program.
Critics say the red light cameras don't have state approval.
A similar lawsuit was thrown out by the Illinois Supreme Court as two justices recused themselves for unknown reasons.
