Protesters gathered out front of the Colorado Supreme Court Building to protest fracking before a hearing on local communities and fracking

DENVER, CO - DECEMBER 09: Protesters gathered out front of the Colorado Supreme Court Building to protest fracking before hearings on local communities and fracking on Wednesday, December 09, 2015. The two hearings focus on Longmonts 2012 ban on fracking and Fort Collins 2013 moratorium. In both cases, the oil and gas industry sued to overturn these measures, contending that the local governments have no power to regulate the industry, or control the location and practices of any oil and gas activities in their borders.
