delivered the opinion of the court.
Unless the construction of a provision of the constitution of the state or of the United States is necessary to a determination of this action, this court is without jurisdiction to entertain it. — Mills’ Ann. Code, see. 406a.
On behalf of the auditor and treasurer, the attorney general contends that the proposition involved is the power of the court to take oral or other extrinsic testimony for the purpose of contradicting or impeaching an enrolled, signed and approved act, or the journals of the general assembly relating to its passage; or, in other words, when the validity of a statute is attacked, no evidence is competent to support the attack save and except the enrolled bill itself and the journals of the legislature. This is undoubtedly the general rule when it is sought to impeach the contents or attack the .validity of a statute which was actually signed by the presiding officers of the respective branches of a legislature, with this modification: That in some jurisdictions it is held that the enrolled bill, when signed, is conclusive and cannot be impeached by the journals of the body passing it, while in other jurisdictions it is held the journals may be resorted to for the purpose of ascertaining the validity of an act. This difference in the decisions, however, is of no moment in this case. *459Whether or not the rule adopted or the law declared on the subject by the courts of last resort is based upon constitutional construction, the ground of public policy, or because to hold otherwise would invade the constitutional authority of a co-ordinate branch of the government, it is not necessary to discuss at this time because the question which the attorney general insists is the one upon which the decision in this case must rest is not involved. Plaintiff is not attempting to impeach the bill passed by the general assembly and signed by the respective presiding officers of the two houses, or contradict the legislative journals relating to it, but, on the contrary, is only seeking to show that what purports to be House Bill No. 433, lodged with the secretary of' state, is not the House Bill No. 433 which the journals recite was passed and signed by the president of the senate and the speaker of the house, because after these steps were taken the body of the bill was removed and in its stead other pages were substituted containing items not mentioned in the bill as passed and signed, to which the page of that bill upon which the signatures of the presiding officers appeared, was attached, or, to be more precise, is only attempting to establish that the bill as passed and signed made no appropriations of the public funds, because all amounts were left blank, while by the substituted pages, these blanks were filled, so that the original bill made no appropriation whatever, and that which was afterwards substituted in its stead did purport to appropriate the public funds of the state for the purposes specified.
The court received testimony on these issues and found that the statements of the complaint in this respect were true. This was not contradicting or impeaching any record, neither was it invading any legislative function. No constitutional provision is pointed out which would inhibit this action. The aver*460ments of the complaint and the testimony do not in any sense relate to what took place in passing the bill, but as to what occurred subsequently; so that the theory of the complaint, as far as noticed, and the purpose of the testimony introduced was not to contradict either the bill as signed or the legislative journals, but to establish which was House Bill No. 433, and uphold it. So far as this case is concerned, the bill actually signed by the presiding officers of the two branches of the general assembly, constitutes the record to which resort must be had to ascertain this fact. What is or is not a record is a matter of evidence, and may be proved like any other fact.—Brier v. Woodbury, 1 Pick. 362; Dyer v. Brogan, 11 Pac. (Calif.) 589; Louisville & N. R. Co. v. Malone, 22 Southern (Ala.) 897; 20 Enc. Law, 1 ed. 515.
In determining this fact, no constitutional question is involved, because the only ones which could possibly be presented in that instance, would relate to the admissibility and sufficiency of testimony and pleadings. These must be determined by the usual rules on these subjects, without regard to any constitutional provisions, either federal or state.
It is claimed there are other constitutional questions raised. Even if this be true, the situation would not be changed, because the determination of any such questions would not affect the only one of fact upon which the judgment is predicated. The validity of the bill does not depend upon whether constitutional provisions in its'passage have been observed or violated, but wholly upon the one question of fact as to whether that which the trial court declared to be of no force and effect was or was not the bill which the general assembly passed, as evidenced by the one which the president of the senate and the speaker of the house authenticated by their signatures. The determination of this fact being in no manner depend*461ent upon the solution of any constitutional question, the writ of error must he dismissed.
It may be said that we have, in effect, decided this case and affirmed the judgment of the district court. If this be true it is the inference which follows the reasons given to support the conclusion that no question is involved which, under our dual system of reviewing the judgments of inferior tribunals, vests this court with jurisdiction in this instance.—Board Pub. Works v. Denver Tel. Co., 28 Colo. 401.
Writ dismissed.
