The defendant used machinery to illegally mine more than 100,000 tons of marl and mud shale outside the red line of construction of a forest farm in Yongning Town and Beiyanshan Avenue, Pukou District, Nanjing City without a mining license. Alongside criminal proceedings, the People's Procuratorate of Nanjing City claimed that the illegal mining had caused damage to national mineral resources and the ecology and environment and harmed the public interest. It initiated a civil action and requested the court to order the defendant to bear tort liability for ecological damage and compensate the restoration costs of ecological and environmental damage. The court held that the defendant was liable for compensation for loss of ecological resources and administrative expenses for damage assessment.
