Members of the leftist opposition party, the Democratic Pole and La Cumbre Agraria, (a social movement in Colombia) filed a lawsuit challenging Article 173 of the National Development Plan (NDP) in Colombia. The NDP had already banned new mining licenses, but allowed the 347 licenses granted to mine for gold or oil to remain in effect. The páramo, or moorland, is one of the most important ecosystems in Colombia, providing drinking water for much of the country by storing water in the rainy season and releasing it in the dry season.
