Here are the materials in Spirit Lake Sioux Tribe ex rel. Committee of Understanding and Respect v. NCAA (D. N.D.):
DCT Order Granting NCAA Motion
We posted the complaint here.
Given what I saw in my two years at UND (here is a snippet), I can’t let this go without comment. I just returned from Boulder, attending a conference in honor of David Getches, the leader in American Indian treaty rights litigation. He fought for the very survival of Indian people and Indian tribes, for the right to fish guaranteed by treaty … really for the right to exist. I see this “Committee” assert treaty rights for something as pitiful as a university sports team’s name and logo, despite all of the negative consequences of this name and logo for UND students and faculty, and I am ashamed. I find this assertion of treaty rights deeply offensive. I assume that the 1969 treaty at issue was made in good faith, but treaties between Indian people and others are made for better things than this. So much has been done in good faith by the opponents and proponents of the name and logo. But nothing good can come from the name and logo after all that has happened. Absolutely nothing.

Well said, Mr. Fletcher. As an aside, I will add that as former student who was charged with documenting the history of American Indian students at UND and the history of the Logo, there was never any treaty. To refer to that situation as something that was worthy of treaty-making is an affront to all of our ancestors. Shame. Shame on them.
In complete agreement with you Matthew and Holly. This mascot needs to change and it is past due. Pidamayaye
