The Missouri Supreme Court has struck down a law — drafted based on city funding information revealed during the investigation into the 2014 Ferguson shooting of Michael Brown — that capped revenues raised from traffic fines at 12.5 percent for a group of municipalities in St. Louis County.

Supreme Court Judge Mary Russell, joined by three other judges, ruled on Tuesday in City of Normandy v. Greitens, that the cap, which applied only to the cities in St. Louis County, was an unconstitutional special law since no other municipality in the state had a cap set at that rate.
