The issue of cultural rights on the mountain was the focus of the documentary: Mauna Kea — Temple Under Siege which aired on PBS in 2006 and featured Kealoha Pisciotta. The Hawaii State Constitution guarantees the religious and cultural rights of Native Hawaiians. Many of the state of Hawaii's laws can be traced back to Kingdom of Hawaii law. Hawaiʻi Revised Statute § 1-1 codifies Hawaiian custom and gives deference to native traditions. In the early 1970s, managers of Mauna Kea did not seem to pay much attention to complaints of Native Hawaiians about the sacred nature of the mountain. Mauna Kea Anaina Hou, the Royal Order of Kamehameha I and the Sierra Club, united their opposition to the Keck's proposal of adding six addition outrigger telescopes.
