The city [of Columbus, Ohio] has dropped a lawsuit against Sherwin-Williams Co. and other companies that once made lead paint... Rhode Island was the first state to successfully sue former makers of lead pigment and paint, which can cause learning disabilities, brain damage and other health problems in children. A jury in 2006 found Sherwin-Williams Co., NL Industries Inc. and Millennium Holdings LLC [part of Access Industries] liable for creating a public nuisance by manufacturing a toxic product. The state Supreme Court, however, said the lawsuit should have been dismissed at the outset... The state of Ohio, the only other state that sued, still plans to continue with its lawsuit, said Jim Gravelle, a spokesman for the attorney general's office.
