Utah Code § 9-9-203

(1) If the governor receives a resolution signed by the majority of any tribe, tribal council, or other governing body duly recognized by the Bureau of Indian Affairs of any tribe, community, band or group in the state certifying the results of a special election expressly ceding criminal or civil jurisdiction of the Indian tribe, community, band, or group or its lands or any portion thereof to the state of Utah within the limits authorized by federal law, the governor shall either accept or reject the cession of jurisdiction within 60 days. (2) If the governor accepts jurisdiction, the governor shall issue a proclamation within 60 days to the effect that civil or criminal jurisdiction shall apply, subject to the limitations of this chapter, to all Indians and all Indian territory, country, lands or any portion thereof of the Indian body involved to the extent authorized by the resolution. Failure to issue the proclamation within the time prescribed is considered a rejection of the assumption of jurisdiction.
