FPIC is a right recognized in the United Nations Declaration on the Rights of Indigenous Peoples. Really though, this should be considered a basic human right. Its already a constitutional right of the State of Washington which in Article 1, section 1 says: “All political power is inherent in the people, and governments derive their just powers from the consent of the governed, and are established to protect and maintain individual rights.”
Consent is always informed consent because nobody can truly consent through fraud. You cannot consent after an event and so it must be done prior to whatever is being done. You also cannot consent through force or coercion, it must be free and voluntary. Any government seeking to rule through force and fraud is both illegitimate and immoral. Not only would I advocate for these Principles, but I believe as a Libertarian like the late Lakota activist Russell Means I already do.
