arena. During the COVID-19 pandemic the Ralph was being considered by the NHL to potentially host playoff games due to North Dakota's low population density and the high quality of the REA. Controversy Midway during construction, Ralph Engelstad threatened to withdraw his funding if UND's Fighting Sioux sports teams were renamed in deference to political pressures. In an effort to make the prospect of removal a prohibitively costly measure, the Fighting Sioux logo was strategically placed in thousands of instances in the arena, including a large granite logo in the main concourse. After the NCAA barred several universities that use Native American imagery from hosting post-season tournaments or wearing such imagery in post-season play, UND sued the NCAA. A preliminary injunction was granted that would have allowed the Fighting Sioux to both host post-season events and wear their regular uniforms while the lawsuit was in progress. The legal papers filed in support of UND pointed out that the Florida State Seminoles have not been required to change their name, thus raising the possibility that the decision regarding the UND Fighting Sioux was arbitrary and capricious. In addition, the legal papers noted that UND has a Native American Studies program, has Native Americans on its faculty, and has a significant Native American student population. The lawsuit with the NCAA was settled under the condition that UND had three years to gain tribal support from both Sioux nations in North Dakota, or retire the Sioux name and logo. After the three years expired, permission was obtained from only one of the two Sioux tribes. The North Dakota Legislative Assembly passed a law requiring the University to retain the name in June 2011, but then repealed the law in November 2011. A statewide vote was held in June 2012, and the citizens of North Dakota voted to discontinue the Sioux name, and on October 22, 2012 crews removed signage that declared "Home of the Fighting Sioux" from the face of the building. The 2012 vote also banned UND from choosing a new name for three years. After the nickname ban expired in 2015, the university held two rounds of online fan voting from a suggested list of nicknames; the final selection of Fighting Hawks was adopted in November of that year.
