delivered the opinion of the court.
By here summarizing- the respective contentions of the parties, the questions for decision will be clearly presented at the outset.
1. The first‘position of plaintiff is that the statutory decree of 1895 is binding on the owners of the Sisson Ditch, and cannot be legally reviewed or over*453turned by them after the lapse of two years from its entry; second, that the 1897 decree is void and may be canceled, and its enforcement enjoined by the plaintiff, because its execution would injuriously affect plaintiff’s vested rights. The defendants take the opposite view and further say that under the irrigation statutes an application for adjudicating such priority may be made by appellants and granted by the court without limitation as to time. They admit that the decree of 1897 is void as to the owners of the X. Y. canal, but say that plaintiff, not being a party to it, cannot move to set it aside, and, in any event, in the absence of an allegation in the complaint that the Sisson priority was not, in truth and fact, as of date January 1, 1876, the plaintiff cannot maintain an action to have annulled the decree which so determines.
Several questions are thus presented for decision, the first and most important of which is whether a ditch owner who appears in a statutory proceeding, properly brought and conducted under the so-called irrigation statutes for settling water-right priorities, and files his verified claim of priority and then refuses to offer proof in support thereof, but permits more than two years to expire after the entry of the final decree, may, in a new statutory proceeding under said acts, or by an action in the appropriate district court, be heard to assert a priority inconsistent with, or antagonistic to, the water priorities determined in such former statutory adjudication. The appellants’ first proposition is that, though their grantor was notified of, and appeared in, the statutory proceeding which culminated in the decree of 1895, yet as he declined to offer proofs, and there was no provision of the decree purporting to ascertain or determine what his actual priority was, they, his grantees, are at liberty at any time to initiate a new proceeding *454finder the irrigation statutes, and have their priorities determined, even though its effect be to overturn the priorities of the earlier decree. They say that section 22 of the act of 1881 (Mills’ Ann. Stats., sec. 2421), is authority for this contention. It provides, in substance, that no claim of priority of any person who has failed or refused to offer evidence under any adjudication shall be regarded by any water commissioner in distributing water in times of scarcity, until such time as such party shall have, by application to the court having jurisdiction, obtained leave and made proof and secured a decree of the priority of right to which such ditch shall be justly entitled, which leave shall be granted in all cases upon such terms as to notice to other parties interested on payment of costs and upon affidavits or petitions sworn to, showing the rights claimed.
We cannot give the provisions of this section the unlimited scope claimed for it. The failure or refusal to offer evidence referred to therein may be by a party who has appeared in the proceeding and might have established his priority, or it may be because, not having been notified, and not appearing, no opportunity was given him to sustain his claim. If the failure or refusal was of the first kind, then under section 26 of the act (Mills’ Ann. Stats., sec. 2425) the party may have a re-argument or review of the decree, with or without additional evidence, if he applies for it at any time within two years from the entering of the decree. That section, however, provides that if the request therefor is not made within such period, no such review or re-argument can be had. It thus seems clear that one who is a party to a statutory adjudication who appears in the proceeding and files his verified statement of claim but refuses to offer proof, cannot be heard thereafter to object, unless within the statutory period of two *455years he applies for a re-argument or a review. This limitation of the right of a party to a review is exclusive, and if he neglects to avail himself of it, his right is gone. If the refusal or failure is of the other character, the person has the right under section 34 of the act (Mills’ Ann. Stats., sec. 2434), at any time within four years after the decree is rendered, to establish his priority by an appropriate suit or action that was allowed in any court having jurisdiction before the passage of these special statutes. The provisions of the statutes should be construed together, and while the language of section 22 (Mills’ Ann. Stats., sec. 2421), taken by itself, might seem to give to a person who appears and files his statement, but fails or refuses to offer evidence in its support, the right to come into the appropriate court to make proof of a priority at any subsequent time; yet, taken in connection with other sections relating to limitations upon further action, the reasonable construction is that he must make application for relief within two years. If not appearing, or not notified — in other words, if one is not a party — he may establish his priority at any time within four years in an appropriate action. The section still applies to priorities of a date later than the lowest one fixed by former decrees.
The definition which appellants place upon “party” is entirely too narrow. They would limit it to one who has notice of the proceeding and appears therein and offers proof and gets a decree. But one is a party to these proceedings who has due notice thereof, or who appears therein, or files his statement of claim; and the fact that he does not see fit to offer proof in support thereof, or fails to have his rights adjudicated, makes him as much a party to the proceeding as though he offered proofs and obtained a decree for his claimed priority.
*456Appellants cite in support of their contention a well considered Wyoming case — Farm Investment Co. v. Carpenter et al., 9 Wyo. 110. A number of important questions are there considered and determined, and among other things the court, • speaking by Potter, C. J., held that on the ground alone that while several priorities were established, no amount of water was awarded to a particular existing claimant who did not participate in the proceeding by appearance, submission of proofs, or otherwise — it was unable to say that the decree of the board under consideration was res judicata as to, him and his rights. That, however, is not the case we are considering. Here appellants’ grantor appeared in this proceeding and filed a verified claim, though no evidence in support of it was offered. The Wyoming court was careful to say that the scope of its decision was confined to the facts shown by the pleadings in the pending case, which was whether an adjudication of the board of control of that state which allots no water to an existing non-appearing and non-participating claimant amounts to a determination and disposition of his rights. We observe first that that opinion clearly shows that the scope and effect of the statutory proceedings for regulating the use of water in that state and for settling the priorities of water rights are in many important respects essentially different from those which are in forcé in Colorado. The statutes of Wyoming on this subject in force before the adoption of. its constitution were very similar to the present law of this state, but after the adoption of that instrument an entirely different system was established. The settlement of priorities in that state is made by a state board of control, while in this state it is by the district courts. The proceeding before the board is instituted by the board itself in an official capacity representing the public, and, as stated *457by Potter, C. J., it is “for the purpose of ascertaining the precise rights and priority of each appropriator, to the end that the public records may be furnished an accurate and defined statement thereof, and as an aid to adequate and effective state control of the public waters.” In Colorado the object is to determine the relative rights and priorities as between different ditches, and in terms the priorities are awarded to these instrumentalities for enjoying the rights, and the adjudication is made by a constitutional judicial tribunal. In the, Wyoming case it was said that a determination of the rights and priorities of several claimants does not necessarily involve the denial of all rights and claims of every other person not mentioned, but the court immediately said that if the proceeding was one wherein the parties represented in the decree were seeking to quiet their respective titles as against every other person, the result might be altogether different.
It is manifest from a careful examination of our statutes and from the repeated decisions of our courts that our proceeding, if not technically one.to quiet titles, is quite analogous thereto, for the object is not merely to settle the individual and several priorities of the different appropriators, but the relative priorities as between the different ditches, in which every claimant is seeking to establish his right as against every other person. There are other substantial differences between the proceedings under the two systems, but enough has already been indicated to show that a decision under the Wyoming statute, even if it should go to the extent of holding that proceedings therein are not res judicata as to the parties thereto, would not be in point with us.
The court in the Wyoming case further observed that the determination required to be made by the board of control was primarily administrative rather *458than judicial, and while it acts judicially, its power is quasi judicial only, and its jurisdiction was upheld in part because by other provisions of the act a review of its decision by the courts of the state is allowed, and because quasi judicial functions of the board were authorized by the provisions of the Wyoming constitution. The reasoning of the Wyoming case is authority for the doctrine, which we now lay down, that where a claimant of a priority to the use of water for irrigation appears in a statutory proceeding for the adjudication of such priorities and files a statement of h'is claim, the decree thereunder is res judicata as to him and his rights, though he neglects to offer proofs; and unless within the statutory period of two years he applies for a review, he may not thereafter, in any proceeding or action, be heard to object to the same. We do not see why the familiar rule, applicable to judgments in civil actions, does not apply to a final decree in these special proceedings, viz.: that whatever has been, or with propriety might have been, decided thereby, is res judicata as to the parties thereto and their privies.
This conclusion, while not expressly ruled by any of our previous decisions, is in principle supported by them. In Greer v. Heiser, 16 Colo. 306, the court said that it was a grave question whether an adjudication under these irrigation statutes could be had modifying the general decree regulating the distribution of water in the entire water district. But where no interests are involved or affected, save those of persons who are parties to such subsequent adjudication, under section 34 (Mills’ Ann. Stats., sec. 2434) they were permitted, within four years from the entry of the decree, to have their rights judicially ascertained, though notified of the former proceeding but suffering default. The court, however, clearly intimated that were it not for the four years’ statute *459permitting one to maintain the action, the statutory decree would he res judicata as to him. The effect of this decision, so far as concerns the right to an independent action of a person who appears in the statutory proceeding or is notified thereof, is modified by the subsequent case of Montrose Canal Co. v. Loutsenhizer Co., 23 Colo. 233, which will he further referred to.
In Nichols v. McIntosh, 19 Colo. 22, it was held that a person who, at the time of the statutory proceedings for ascertaining priorities, was absent from the state and not served with process, and did not enter an appearance therein, might thereafter have his rights judicially determined. The reasoning of the opinion proceeded upon the ground that the limitations of the statute do not apply to one who has not liad his day in court, and logically makes the statutory decree res judicata as to an unproven claim of one who appeared in the proceeding.
In Louden Co. v. Handy Co., 22 Colo. 102, it was held that the statutory proceeding was in the nature of a proceeding in rem for the settlement of all claims to priority within the particular water district,'and a decree therein was res judicata at least as to all who appeared as parties thereto and participated in the proceedings. In Boulder Co. v. Lower Boulder Co., 22 Colo. 115, the same announcement was made. In the Loutsenhizer case, supra, and in Handy D. Co. v. South Side D. Co., 26 Colo. 333, a construction was placed on the four-year statute of limitations excluding from its operation parties to the statutory proceeding. It was there said that parties have an opportunity for re-argument or review within two years, and that the four years’ statute was for the benefit of persons who were not parties to the statutory adjudication, or whose rights grow out of matters arising subsequent to the decree.
*460So that from these decisions npon the statutes it seems clear that a party to the statutory proceeding, even though he offers no proof in support of the claim which he files, is bound by the provisions of the decree unless within the two years ’ period of limitation he applies for a review. What the effect of such decree is as to one who has no notice whatever, or who did not appear, is not in this case, and we limit the decision to the facts of the pending case.
2. It is contended by plaintiff and conceded by defendants that the decree of 1897, establishing for the Sisson Ditch No. 1 a priority as of date January 1, 1876, is absolutely void as to the plaintiff. But it is said by defendants that the complaint is insufficient because it does not show any merits- in behalf of the plaintiff, in that there is no averment that the decree of priority of the Sisson Ditch was not, and is not, in reality as decreed. This argument is based upon the familiar rule, announced in many decisions, that a court of equity at the instance .of the judgment debtor will not relieve against a judgment at law in the absence of an allegation of a meritorious defense thereto by him. Whatever the rule may be in other jurisdictions, the doctrine here, as announced in Wilson v. Hawthorne, 14 Colo. 530, is that a judgment rendered without obtaining jurisdiction of the person may be impeached by a proceeding in equity, or in an answer to an action seeking to enforce the judgment where equitable defenses are allowable as in this state, although in the compláint there is no allegation of merits. The court said: ‘ ‘ The cross-complaint in this action contains no allegation that the defendant Henry Wilson was not liable in the original action equally with the defendant David B. Had the demurrer been specially interposed and sustained for the want of such averment, the ruling would not have been erroneous. The jurisdiction of equity *461should not be invoked- except by a complaint alleging that real injustice has been or is likely to be done. But we are not prepared to say that such averment is essential or traversable. The showing of merits should not be required to the extent of compelling a party against whom a judgment has been obtained, without jurisdiction over his person, to come into a court of equity and assume the burden of disproving his liability.” It was further said that while the court may require an allegation of merits as an earnest of good faith from the party seeking relief from a judgment void for want of jurisdiction of the person of the judgment debtor, still, even if made, the allegation is not traversable, and the complaint is good without it. To the same effect, also, are — Great West M. Co. v. Woodmass, etc., Co., 12 Colo. 46, 60; DuBois v. Clark, 12 Colo. App. 220; Smith v. Morrill, 12 Colo. App. 233; Keely v. East Side I. Co., 16 Colo. App. 365; High on Injunctions (2 ed.), §§ 229, 230.
If a judgment debtor, in such circumstances, is not required to allege and prove merits, a fortiori should a stranger be exempt from doing so. But it is said that a stranger cannot maintain an action to cancel a void judgment, for so long as the parties themselves elect to have it stand, he has no right to set it aside. Unquestionably, the general rule is that a stranger may not maintain the action. But where the enforcement violates his rights, the stranger'is affected by the judgment, and may be relieved against it. See authorities collected in 15 Enc. Pl. & Pr. 250. So, also, if the void judgment constitutes a cloud upon the title of a stranger, the latter may have it canceled as to him — -17 Am. & Eng. Enc. Law (2 ed.) 847, note 1; 839, note 4. That plaintiff here certainly would be seriously injured by the enforcement of the decree of 1897 becomes apparent from *462the consideration which we now give to another of defendants ’ contentions.
They say, even though the judgment is void as to the plaintiff, the decree complained of went too far in absolutely nullifying and setting it aside as to other parties to the statutory adjudication proceedings who are not here complaining of it. Ordinarily the criticism would be good, but when the relative rights of those holding statutory decrees are considered, the objection vanishes. A certified copy of the statutory decree is produced to the water commissioner, and in distributing water in times of scarcity he is required to observe the decreed priorities, distributing the same in accordance with the respective priorities, to the earliest one first, and so on in succession. It appears from the' allegations of the complaint that in times of scarcity of water in the Arkansas river in this district, the plaintiff does not get the quantity of water decreed to it because earlier priority holders consume the same before its priority is reached. The defendants’ decree of 1897 awarded them a priority as of January 1, 1876, antedating all of the priorities which were made by the previous decree of 1895. If the provisions of the later decree are enforced in times of scarcity, necessarily the head-gate of plaintiff’s canal would be shut down before those holding priorities of an earlier date were closed. So, in order fully to protect plaintiff in the enjoyment of its decreed rights against this void decree, it was necessary to restrain its enforcement against all of the consumers. These relative priorities are so interlaced and dependent one upon the other, and the distribution of water by the officers of the state is so made, that no practical decree can be rendered by the court in the pending , case except one setting aside and annulling the void decree, and preventing *463its enforcement, as against all those whose priorities were adjudicated by the final decree of 1895.
The judgment is right and should he affirmed, and it is so ordered.
Affirmed.
