In remarks delivered on the Senate floor on climate change, Senator Benjamin Cardin (D-Md.), referred to several statistics in the amicus brief filed on behalf of the National League of Cities (NLC) nd the U.S. Conference of Mayors (USCOM) by CCL in Baltimore's lawsuit against major oil companies for the effects its misrepresentations on the effects of fossil fuels have had on the city's infrastructure. 

     CCL has filed amicus briefs in several city, county, and state lawsuits on the issue on behalf of the NLC, USCOM, and the International Municipal Lawyers Association. In support of Baltimore's position that their case belongs in state court, CCL filed briefs in both the U.S. Supreme Court, where the brief was referenced twice in oral argument, and in the U.S. Court of Appeals for the Fourth Circuit, where it was recently re-argued.
