On September 20, 2016, Dave Archambault II addressed the UN Human Rights Council in Geneva, Switzerland, where he called upon all parties to stop the construction of the Dakota Access Pipeline. Citing the 1851 Treaty of Traverse des Sioux and 1868 Treaty of Fort Laramie, two treaties ratified by the U.S. Senate that recognize the Sioux's national sovereignty, Archambault told the Council that the oil companies and the government of the United States have failed to respect our sovereign rights. On September 22, 2016, Victoria Tauli-Corpuz, a United Nations expert on the rights of indigenous peoples, admonished the U.S., saying, The tribe was denied access to information and excluded from consultations at the planning stage of the project, and environmental assessments failed to disclose the presence and proximity of the Standing Rock Sioux Reservation. She also responded to the rights of pipeline protesters, saying, The U.S. authorities should fully protect and facilitate the right to freedom of peaceful assembly of indigenous peoples, which plays a key role in empowering their ability to claim other rights. According to the statement by Alvaro Pop Ac, Chair of the United Nations Permanent Forum on Indigenous Issues, the project was proposed and planned without any consultation with the Standing Rock Sioux or others that will be affected by this major project. According to the USACE's data there had been 389 meetings with more than 55 tribes, including nine meetings with The Standing Rock Sioux Tribe. Kelcy Warren has stated that the company is not on any Native American property.
