[1] The petitioner Tolerton is charged with murder in the first-degree in the respondent court. The district attorney has stated that he intends to death qualify the jury and seek the death penalty. The petitioner has filed motion challenging the constitutionality of Colorado's Death Penalty Statute. Section 16-11-401, et seq., C.R.S. 1973 (1980 Supp. to 1978 Repl. Vol. 8). Petitioner has also challenged the unconstitutionality of the death qualification procedure.
[2] The respondent court has set these motions for hearing and determination before a panel of three district judges of the Eighteenth Judicial District of Colorado. This procedure is challenged by the petition for relief in the nature of prohibition filed by the petitioner Tolerton. We issued a rule requiring the respondent court to show cause why such a procedure should not be prohibited and we now make the rule absolute.
[3] The respondent district court has no authority to set these motions for hearing or for determination by a multi-judge panel. The clear import and obvious intent of sections 13-5-131, 132 and 133, C.R.S. 19731 is to empower a district court judge to rule on such matters only when sitting separately. Section 13-5-133(3) clearly mandates that judges of a district court in a multi-judge district may sit en banc only *Page 1021 for the limited purposes set forth in the statute. The purposes set forth in the statute do not include the hearing or determination or motions or the making of decisions, orders, decrees, or judgments in criminal or civil cases filed in the district court.
[4] The statutory predecessors of these statutes had substantially the same language. In People ex rel. Rucker v. District Court, 14 Colo. 396,24 P. 260 (1890), these statutory provisions were interpreted as follows:
[5] "Section 3 of said act provides that the judges may sit in bank for certain specified purpose, and `for no other purpose whatever.' The language of the act, as well as the manifest object of providing additional judges of the same court, leave no room for construction as to the mode in which the judges are required to set and transact business. In the trial of causes, and in the hearing and determination of any matter of purely judicial cognizance pending in the district court, each judge must sit and act alone. He must exercise all the powers and functions of the court and assume the full responsibility in the decision of each and every cause, demurrer, motion, and the like, coming before him for adjudication, as if he were the sole judge of said court. Two or more judges, by sitting together, cannot share or divide such responsibility. They cannot thus jointly hear and determine, and render a valid and binding judgment or order in any cause."
[6] We hold that sections 13-5-132 and 133, C.R.S. 1973 have the same meaning as their predecessor statutes and we therefore adopt the same interpretation for them. We rule that the three-judge panel procedure for hearing and determining the motions in this case is invalid and thus prohibited.
[7] The rule to show cause is made absolute.
