Utah Const. art. XXIV, § 6

[Criminal prosecutions begun and crimes committed before statehood.] All criminal prosecutions, and penal actions, which may have arisen, or which may arise before the change from a Territorial to a State Government, and which shall then be pending, shall be prosecuted to judgment and execution in the name of the State, and in the court having jurisdiction thereof. All offenses committed against the laws of the Territory of Utah, before the change from a Territorial to a State Government, and which shall not have been prosecuted before such change, may be prosecuted in the name, and by authority of the State of Utah, with like effect as though such change had not taken place, and all penalties incurred shall remain the same, as if this Constitution had not been adopted.
