ACQTC, Inc. and Thunderhorse filed a Motion to Intervene as the Legal Sovereign of ACQTC, Inc., and submitted an 86-page multidisciplinary study about the sites. Eventually, Attorney General Richard Blumenthal indicated he would file for a permanent injunction after Thunderhorse pointed out that the original donors of the land did so with the stipulation that the Parks be used for the public (precluding a golf course for the wealthy). In 2003, Thunderhorse, who is now legally blind, filed a Pro Se litigation under the ADA (Americans with Disabilities Act) about the conditions in Texas prisons, because they reportedly did not adequately accommodate disabled prisoners. This led to an investigation by ADVOCACY, Inc. In late 2004, Thunderhorse filed suit in Pro Se under the RLUIPA (Religious Land Use and Institutionalized Persons Act) after TDCJ defendants reportedly violated three previous out-of-court settlements. When the U.S. Magistrate Judge ruled against Thunderhorse, he appealed to the Fifth U.S. Circuit Court of Appeals in New Orleans. In a four-page PER CURIAM OPINION, the 5th Circuit vacated the District Court's ruling and remanded the case for "further proceedings." Artist Thunderhorse has published a special series teaching the basics of many Native American traditional crafts. His book, Return of the Thunderbeings (by Iron Thunderhorse and Donn LeVie, Jr., Santa Fe, Bear & Co., 1990, ), has chapters on Shamanic art and is full of symbols and designs used as iconography in tribal arts and crafts. All of Thunderhorse's books, booklets, and scholarly studies contain his line drawings, maps, and charts. Four of his illustrations appear in Voices of Native America and he designed the cover for his only authorized biography, Following the Footprints of a Stone Giant: The Life and Times of Iron Thunderhorse. Thunderhorse's historical pictographic portraiture of Tecumseh is on display at the Museums at Prophetstown State Park in Lafayette, Indiana. His masks are in the private collections of Barbara Hand Clow, David Wagner, and Yehwehnode. At the Indian Trading Post and Powwow Museum, just south of Indianapolis, Indiana, many Thunderhorse originals were on display for several years. Other works have been on display in Louisville, Kentucky; New York City; Orange, Texas; and elsewhere. A permanent exhibit of Iron's maps and portraits reside at the Quinnipiac Dawnland Museum in Guilford, Connecticut, while a large collection of his work remains at the ACQTC National Office in Milltown, Indiana. At gatherings, his creations have been used as
