Glamis Imperial, the Canadian goldmining company, has served notice that it will seek to use NAFTA and UNCITRAL (United Nations Commission on International Trade Law) to challenge through international arbitration a U.S. Interior Department decision that has hindered a Glamis open pit gold mining project because it would have damaged Quechan Indian Pass, a culturally sensitive site in southeast California. Glamis is also claiming that the state of California expropriated $50 million by passing environmental legislation in early 2003 requiring backfilling of open pit mines.
