Colorado laws on pardon and parole can be found in C.R.S. 16-17-101 through C.R.S. 16-17-102.
Pursuant to C.R.S. 16-17-101, the governor is fully authorized, when s/he deems it proper and advisable and consistent with the public interests and the rights and interests of the condemned, to commute the sentence by reducing the penalty in a capital case to imprisonment for life or for a term of not less than twenty years at hard labor.
Pursuant to C.R.S. 16-17-102, after a conviction, applications for commutation of sentence or pardon for crimes committed must be accompanied by a certificate of the respective superintendent of the correctional facility, showing the conduct of an applicant during his or her confinement, and evidence of former good character if any. Before the governor approves such application, it must be first submitted to the present district attorney of the district in which the applicant was convicted and to the judge who sentenced and the attorney who prosecuted at the trial of the applicant. Those persons can provide information to the governor regarding the merits of the application. Good character prior to conviction, good conduct during confinement in the correctional facility, the statements of the sentencing judge and the district attorneys, if any, and any other material concerning the merits of the application must be given such weight as to the governor may deem just and proper, in view of the circumstances of each particular case, a due regard being had to the reformation of the accused. The governor must have sole discretion in evaluating said comments and in soliciting other comments s/he deems appropriate[i].
