CSTC has at times included other bands.
Lake Babine Nation band left CSTC in 1991.
Lheidli T'enneh left in 1992.
Burns Lake Band withdrew in 1993 but subsequently returned. In 2006 the CSTC commissioned and oversaw the Aboriginal Interest and Use Study (AIUS) to investigate impacts of the
Enbridge oil pipeline proposal. In October 2010 the Supreme Court ruled against the tribal council in CSTC vs. Rio Tinto Alcan. The court ruled that nobody was obligated to come to First Nations to consult on the issue of the Electricity Purchase Agreement (EPA) structured between BC Hydro and Alcan. However, the high court noted that, "The Kenny Dam was built without consultation and at the time, CSTC or its member nations were not permitted to hire a lawyer under the Indian Act. That said, the project itself was built without consultation and the Supreme Court now says First Nations can receive compensation on the lack of consultation." The CSTC had claimed that, "[i]n the 1950s, the government of British Columbia authorized the building of a dam and reservoir which altered the amount and timing of water flows in the Nechako River. The First Nations claim the Nechako Valley as their ancestral homeland, and the right to fish in the Nechako River, but, pursuant to the practice at the time, they were not consulted about the dam project." == Demographics ==
