A federal court dismisses a class-action suit brought by a St. Louis County couple against the city of Hannibal and its red-light camera program.

Jacob and Sarah Blair filed the suit in Missouri’s Eastern District Court last August, claiming the red-light program unjustly enriched the city and violated the couple’s constitutional rights.

The Blairs had both been ticketed and fined for running red lights in Hannibal. The couple had sought damages and class-action status for drivers who were cited and fined between June of 2007 and November of 2013. That’s when the city changed its red-light camera ordinance to line up with state law.

In the order issued Tuesday, the judge in the case dismissed six claims against the city of Hannibal, including constitutional violation, unjust enrichment, abuse of process and civil conspiracy.
