Here are the materials in United States v. White Plume (D.S.D.):
140 Oglala Sioux Tribe Amicus Brief
An excerpt:
What is material to the court’s analysis is the shifting national focus on industrial hemp as a viable agricultural crop and the decision of the Attorney General of the United States to engage in a dialogue with the various tribes on the relationship between the CSA and the Agricultural Act of 2014. The government did not challenge Mr. White Plume’s assertion that “[w]ith the Agricultural Act of 2014, the Federal government joined the twenty-two states that have enacted legislation on industrial hemp.” (Docket 125 at p. 7) (reference omitted). Nor did the government challenge the representation that seven states have ventured into the area of agricultural or academic research of industrial hemp.
