Specht v. Patterson, 386 U.S. 605, 87 S.Ct. 1209 (1967). [Held: petitioner who was convicted but not sentenced for indecent liberties under one statute, and who thereafter was sentenced under Colorado Sex Offenders Act for an indeterminate term of from one day to life without notice and a full hearing, was not accorded equal protection or due process where latter Act did not make commission of a specified crime the basis for sentencing, but made one conviction the basis for commencing another proceeding to determine whether a person constituted a threat of bodily harm to the public or was an habitual offender and mentally ill, which was a new finding of fact that was not an ingredient of offense charged.]
