In 1960, a stand at the stadium in Toowoomba, Australia, was named the "E. S. '******' Brown Stand" honoring 1920s rugby league player Edwin Brown, so nicknamed since early life because of his pale white skin; so known all his life, his tombstone is engraved ******. Stephen Hagan, a lecturer at the Kumbari/Ngurpai Lag Higher Education Center of the University of Southern Queensland, sued the Toowoomba council over the use of ****** in the stand's name; the district and state courts dismissed his lawsuit. He appealed to the High Court of Australia, who ruled the naming matter beyond federal jurisdiction. At first some local Aborigines did not share Mr Hagan's opposition to ******.[72] Hagan appealed to the United Nations, winning a committee recommendation to the Australian federal government, that it force the Queensland state government to remove the word ****** from the "E. S. '******' Brown Stand" name. The Australian federal government followed the High Court's jurisdiction ruling. In September 2008, the stand was demolished. The Queensland Sports Minister, Judy Spence, said that using ****** would be unacceptable, for the stand or on any commemorative plaque. The 2005 book The N Word: One Man's Stand by Hagan includes this episode.[72][73]
