Pacific Rim Mining Corp. is a Canadian company that applied for an environmental permit and a mining exploitation concession in El Salvador through one of its subsidiaries in 2004. The environmental permit and the concession were not granted. Three years later, in December of 2007, Pacific Rim Mining Corp. changed the nationality of another subsidiary, Pac Rim Cayman, from the Cayman Islands to the United States. In 2009 this Canadian company used Pac Rim Cayman to stand in its place as the Claimant to initiate this arbitration. A review of the facts underlying this series of events reveals that Pacific Rim Mining Corp. and Pac Rim Cayman have abused the provisions of CAFTA and the international arbitration process by changing Pac Rim Cayman's nationality to a CAFTA Party to bring a preexisting dispute before this Tribunal under CAFTA.
