The alternative writ of mandamus performs the office of the complaint'in an ordinary civil action. It must state a cause of action, and failing- to do so will not support a judgment. Its legal sufficiency may, by the return or answer provided for in the Civil Code, be challenged as upon demurrer and tested under the rules of pleading- applicable to the ordinary complaint, when assailed by demurrer.
The alternative writ before us is somewhat informal and undoubtedly contains unnecessary matter; but, so far as mere form is concerned, we shall hold it sufficient without discussion, and proceed to consider the alleged substantial legal objections that are fairly presented. by respondent’s demurrer.
The subject of water rights has always been justly regarded as one of the most important dealt with in the legislation and jurisprudence of Colorado. Hitherto attention has been mainly directed to the adjustment of priorities and differences between individual consumers; but hereafter, owing to the rapid settlement of the eastern part of the state, the status of the carrier and its relations with the consumer will command the most earnest and thoughtful consideration.
For convenience I shall, throughout this opinion, use the terms “carrier” and “consumer,” meaning the canal company and the tiller of the soil respectively.
The agriculturists in the territory mentioned are; with few exceptions, unable to convey water from the natural streams to their land. The annual rainfall is increasing; yet at present, without irrigation, but a small fraction of the producing capacity of the soil can be utilized, and, unaided, these consumers will for years to come be practically helpless. To the successful cultivation of that region the carrier and consumer are, therefore, equally indispensable. Hence a wise legislative policy and an intelligent judicial construction require a careful consideration of the privileges, powers and duties of the car*587rier, as well as the rights and obligations of the consumer. The courts should protect the consumer in the full enjoyment of his constitutional and statutory rights; but they should also jealously guard the rights of the carrier; and so deal with it (the constitution and statutes perihitting) as to encourage the investment of capital in the construction of reservoirs and canals for the storage and transportation of water.
The pleadings in the case at bar show that respondent is a carrier and distributor of water for irrigation and other purposes. That its canal, two years ago, was upwards of sixty miles in length and capable of supplying water to irrigate a large area of land. That relator is one of the landowners and consumers under the .canal, and can obtain water from no other source; also, that respondent has, undisposed, a sufficient quantity to supply his wants. That he tendered the sum of $1.50 per acre, the annual rental fixed by respondent, and demanded the use of water for the current season, but declined to pay the further sum of $10 per acre also demanded, and to sign a certain contract presented to him for execution. That respondent refused, and still refuses, to grant relator’s request, except upon compliance with these conditions. The remaining essential facts will sufficiently appear in connection with the specific qirestions of law presented, as they are in their proper order discussed.
Does the record show a clear legal right of relator, from the enjoyment of which he is unlawfully precluded by respondent?
Our constitution dedicates all unappropriated water in the natural streams of the state “ to the use of the people,” the ownership thereof being vested in “ the public.”' The same instrument guaranties in the strongest terms the right of diversion and appropriation for beneficial uses. With certain qualifications it recognizes and protects a prior right of user, acquired through priority of appropriation. We shall presently see that after appro*588priation the title to this water, save, perhaps, as to the limited quantity that may he actually flowing in the consumer’s ditch or lateral, remains in the general public, while the paramount right to its use, unless forfeited, continues in the appropriator. But to constitute a legal appropriation, the water diverted must be applied within a reasonable time to some beneficial use. That is to say, the diversion ripens into a valid appropriation only when the water is utilized by the consumer; though the priority of such appropriation may date, proper diligence hav-' ing been used, from the commencement of the canal or ditch.
The constitution unquestionably contemplates and sanctions the business of transporting water for hire from natural streams to distant consumers. The Colorado doctrines of ownership and appropriation (as declared in the constitution, statutes and decisions) necessarily give tli© carrier of water an exceptional status; a status differing, in some particulars, from that of the ordinary common carrier. Certain «peculiar rights are acquired in connection with the water diverted. It is unnecessary now, however, to enumerate these rights in detail. For the present it suffices to say that they are dependent,for their birth and continued existence, upon the use made by the consumer.
But giving these rights all due significance, I cannot consent to the proposition that the carrier becomes a “proprietor,” of the water diverted.
A cursory reading of the statutes might convey the impression that the legislature regarded the carrier as possessing a salable interest in this water. And the constitutional phrase, “to be charged for the use of water,” relating to the carrier’s compensation, might at first glance seem to recognize a like ownership in such use. But construing all the provisions of that instrument bearing upon the. subject in pari materia, the correctness of both of these inferences must be denied. The *589constitutional convention was legislating with reference to the necessities and practical .wants of the people. And this body, in its wisdom, ordained that the ownership of water should remain in the public, with a perpetual right to its use, free of charge, in the people.
By section 8, article XVI, of the constitution, from which the foregoing phrase is taken, the convention recognized the carrier’s right to compensation for transporting w'ater, and provided for a judicial, or quasi-judicial, tribunal to fix an equitable maximum charge where the parties fail to agree. It requires no citation of authority to show that the words “purchase” and “sale,” together with other words of like import, used in this connection by the legislature, must receive a corresponding interpretation. Under the constitution, as I understand it, the carrier is at least a gztcm-public servant or agent. It is not the attitude of a private individual contracting for the sale or use of his private property. It exists largely for the benefit of others; being engaged in the business of transporting, for hire, water owned by the public, to the people owning the right to its use. It is permitted to acquire certain rights as against those subsequently diverting water from the same natural stream. It may exercise the power of eminent domain. Its business is affirmatively sanctioned, and its profits or emoluments are fairly guarantied. But in consideration of this express recognition, together with the privileges and protection thus given, it is, for the public good, charged with certain duties and subjected to a reasonable control.
Were the constitution and statutes absolutely silent as to the amount of the charge for transportation, and the time and manner of its collection, there would be strong legal ground for the position that the demand in these respects must be reasonable. The carrier voluntarily engages in the enterprise; it has, in most instances, from the nature of things, a monopoly of the business along the line of its canal; its vocation, together with the use *590of its property, are closely allied to .the public interest; its conduct in connection therewith materially affects the community at large; it is, I think, charged with what the decisions term a public duty or trust. In the absence of legislation on the subject, it would, for these reasons, be held, at common law, to have submitted itself to a reasonable judicial control, invoked and exercised for the common good, in the matter of regulations and charges. And an attempt to use its monopoly for the purpose of coercing compliance with unreasonable and exorbitant demands would lay the foundation for judicial interference. Munn v. People, 4 Otto, 113, and cases cited; Price v. Riverside L. L. C. 56 Cal. 431; C. & N. W. R. R. Co. v. People, 56 Ill. 365; Vincent v. Chicago & Alton R. R. Co. 49 Ill. 33.
But the constitution is not silent in the particular mentioned. It evinces, beyond question, a purpose to subject this, as other branches of the business, to a certain degree of public control. As we have seen, it provides for a tribunal to which the maximum amount of water rates may be referred, in case of dispute between the carrier and consumer. And I think that, by fair implication, it forbids the carrier’s enforcement of unreasonable and oppressive demands in relation to the time and manner of collecting these rates. Any other view would accuse the convention of but partially doing its -work. For the fixing of maximum rates would be protection, grossly inade-, quate, if either of the parties might dictate, absolutely, the time and conditions of payment. The primary objects were to encourage and protect the beneficial use of water; and while recognizing the carrier’s right to reasonable compensation for its carriage, collectible in a reasonable manner, the constitution also unequivocally asserts the consumer’s right to its use, upon payment of such compensation.
Any unreasonable regulations or demands that operate to withhold or prevent the exercise of this constitutional *591right by the consumer must be held illegal, even though there be no express legislative declaration on the subject.
The contract which' respondent required relator to sign and agree to comply with, as a condition precedent to the granting of his request, contains the following among other conditions: That he buy in advance “the right to receive and use water” from its canal, paying therefor the sum of $10 per acre; also that he further pay “annually in advance, on or before the 1st day in May of each year, such reasonable rental per annum, not less than $1.50 nor more than per acre, as may be established from year to year ” by respondent. If we hold respondent to the literal term used in this contract we must declare the $10 exaction illegal. Respondent cannot collect of relator the sum of $10, or any other sum, for the privilege c-f exercising his constitutional right to use water.
But counsel contend in argument that the foregoing expressions, quoted from respondent’s contract, are not intended to require -the payment of $10 per acre’ for 'a right to use luater. They say this $10 is merely a portion' of the annual “rental” exacted of consumers in advance for the remaining years of respondent’s corporate existence; that instead of requiring, say, $2.50 per acre for each irrigating season in turn, respondent has seen fit to divide this sum into two parts, collecting $1.50 annually, and the residue of $1 each for the remaining ten years of its corporate life, as one entire sum in advance.
This construction of the contract may, under all the circumstances, seem plausible, though I doubt if the courts could accept it; but if accepted the difficulty under which respondent labors would not be obviated.
If the carrier may collect a part of its annual transportation charge in advance for the remaining years of its corporate life, it may collect all. Suppose the company just organized; under counsel’s view the consumer may, there being no legislation on the subject, be com*592pelled to pay the cost of delivering water to him for the entire twenty years of its existence, before he can exercise his constitutional right during a single season.
But there is nothing in the law obliging him to cultivate his land for any particular period. He may not want the water for twenty years, or it may be utterly impossible for him to advance so large a sum at once. In fact, the majority of those who till the soil are too poor to comply with such a demand; to say that they must do so or have no water is to deprive them of their right to its use just as effectually as though the right itself had no existence. It is true these people would not themselves be able to bring water from the natural streams to their farms, and without the carrier they might be compelled to abandon their attempts at agriculture. This consideration, however, only reinforces the position that a reasonable control was intended. The carrier must be regarded as an intermediate agency existing for the purpose of aiding consumers in the exercise of their constitutional right, as well as a private enterprise prosecuted for the benefit of its owners. Yet, if such exactions as the one we are now considering are legal, the carrier might, at its option, in the absence of legislation, effectuate or defeat the exercise of this right; and we would have a constitutional provision conferring an affirmative right, subject for its efficacy in a given section to the greed or caprice of a single individual or corporation.
Besides the extraordinary power mentioned, the carrier would also, under counsel’s view, be able to consummate., a most unreasonable and unjust discrimination. B. could , have water because he can pay for its carriage twenty - years in advance; 0. could not'have water because he is unable to pay in advance for its carriage beyond a season or two.
But, say counsel, O.’s only remedy, and the only remedy of relator and other consumers dissatisfied with the carrier’s terms, is by application to the county commis*593sioners. I reply: First, that so far as the present case is concerned, this suggestion embodies but little consolation. Relatoras land is situate in Arapahoe county. The statute, as it stood .when the proceedings described in the alternative writ took place, did not permit the commissioners of that county to act with reference to respondent’s canal; while, under the constitution, the commissioners of no other county could exercise the necessary jurisdiction. It was utterly impossible, therefore, for relator to secure relief in the manner pointed out, and if the courts could not take cognizance of the alleged grievance he was wholly bereft o*f means of redress. I reply: Second, that the commissioners may be empowered to fix the maximum amount of the rate; that is, they may be authorized to announce a limit beyond which the carrier cannot go. In -my judgment, under the constitution they cannot be vested with authority to establish the exact rate to be charged, or to specify either the time or conditions of payment. The time and conditions of payment are proper subjects for legislation. The legislature doubtless has authority to say that the Tate, whether the carrier adopt the maximum fixed by the commissioners or establish one below such limit, shall be collected annually in advance for each irrigating season; or it can make any other reasonable regulations in these respects. But the legislature itself cannot establish the unreasonable rule we have been considering, which enables the carrier to accomplish a wholesale discrimination between consumers, and deny, if it chooses, to a majority of them, the rights secured them by the constitution. A regulation or rule entailing such results, whether established by the legislature or carrier, must he regarded as within a constitutional inhibition. This conclusion is not based merely upon the ground of private inconvenience or hardship; it rests, as will be observed, upon the higher and stronger ground of conflict with the beneficent purpose of our fundamental law.
*594A further consideration worthy of mention in' passing, . hearing at least upon the unreasonableness of the view urged upon us, is the position of the consumer who pays the charges for twenty years in advance. What assurance has he that the carrier can or will keep its engagement during that period? Its business is attended with considerable hazard, and requires large and continuing expenditures of money. The consumer may find himself without water, and dependent, for the recovery of his large advancement, upon the doubtful experiment of suit against an insolvent company. \
To say that the courts may not interfere, under the circumstances above narrated, is to say that the clear intent of the constitution in relation to a constitutional right may be disregarded with impunity, simply because no express inhibitory constitutional or statutory provision on the subject can be found; also that, for a like reason, one charged with an important duty may condition its performance upon unreasonable and oppressive demands.
I do not usurp the province of the legislature by declaring what would be reasonable requirements as to the time and manner of collecting water rates. My position is that, for the reasons given, respondent’s demand of $10 per acre, as an advance payment of part of the transportation charge for the remaining years of its corporate-life, is illegal as well as unreasonable and oppressive.
Respondent’s enterprise is'of great public importance and benefit. The original construction of its canal cost large sums of money, and its running expenses are necessarily heavy. For a considerable period the capital invested must have been unproductive. These and other circumstances may be proper subjects for consideration by the commissioners, when called upon to establish a-maximum rate. And whenever they become appropriate matters for judicial cognizance, the attention deserved will be received from the courts. But no expenditure, however vast, and no inconvenience, however great, can. *595justify or legalize.the exaction, the consumer objecting, of the demand under consideration, as an absolute condition precedent to use for the current irrigating season.
I must not be understood as intimating that this demand is illegal per se. And if the consumer, prior to 1887, saw fit to waive his right by voluntarily submitting thereto, both the legislature and courts may be alike powerless to relieve him from the legitimate results of his ' contract.
When properly understood, the statutes, in' so far as they relate to the principal subjects examined, harmonize with the conclusions above stated. Counsel’s proposition, that only those consumers who have previously used water are permitted to demand it on payment of the rate established by the carrier, is not sound. The section upon which they rely (1740, Gen. St.) is simply an assurance of the right to continue, under specified circumstances, a use already exercised. It does not operate to repeal section 311 of the General Statutes; this section expressly commands ditch companies, having water in their canals not taken, to furnish the same to the class of persons using it, in the manner named by the articles of incorporation, upon payment of the established rate; the declaration therein that this rate shall be fixed by the county commissioners must be taken with the constitutional condition attached, viz.: “Where application is made to them by either party interested.” But when the company has a fixed rate of its own, with wdiich the consumer is satisfied, no necessity exists for the making of such application. If counsel’s position were correct, the land owner who has never had the use of water would, so far as the statutes are concerned, be wholly at the mercy of the carrier. For section 1740 does not give him the right to water, even when the maximum rate has been fixed by the commissioners.
In view of the foregoing conclusions I need not dwell upon the legality of respondent’s demand that relator, as *596a condition precedent to the use of water for the season of 1886, enter into the written contract before us. This contract contains a number of conditions that appear unreasonable, and, as I construe the constitution and statutes, are of doubtful legality. But it is sufficient to recall the fact that the unlawful demand of $10 per acre for the right to use water is a conspicuous provision therein. Belator could no more be required to execute a contract containing this condition than he could be compelled to comply with the demand in the absence of contract.
It is not necessary to consider what would have been the result had respondent charged $11.50 per acre for the irrigating,season Of 1886, instead of demanding $1.50 for that season and $10 per acre as part payment for future years. Neither is it necessary to speculate as to what respondent would have charged for the season mentioned had the law been understood by its officers according to the construction above given. In view of the pleadings, and especially of the language employed in respondent’s contract, I think that relator, upon the showing made, was entitled to the use of water from respondents canal for the irrigating season specified in the alternative writ. This conclusion is emphasized by the defective condition of the commissioner statute prior to 1881, which left relator helpless so far as action by that body was concerned. I also think that mandamus lay for the enforcement of his rights in the premises.
The demurrer should have beén overruled and the judgment must, therefore, be reversed, appellant recovering his costs.
But courts do not order the performance of impossible acts. This proceeding was instituted for the purpose of compelling respondent to supply relator with water during the irrigating season of 1886. Since then respondent may have changed its annual charge or rate; besides, the only tender or demand appearing in the record were for *597that season. To order compliance with relator’s request for 1886 would be absurd; to .order a delivery of the water for 1888 would be unwarranted. ' To permit an amendment of the alternative writ,-so as to cover the approaching irrigating season, would be to allow the substitution, in this proceeding, of a new and wholly different cause of action and to violate an established rule of pleading.
The judgment is reversed and the cause remanded.
