On April 30, 2008, Crystallex has been denied a key important environmental permit. Crystallex will not be able to construct the mine without the environmental permit.[5]
Crystallex has been litigating for losses relating to nationalization of the Las Cristinas mine in 2008.[6][7][8] On April 4, 2016, Crystallex won their case in front of ICSID and was awarded compensation.
