delivered the opinion of the court:
This is an action under section 254 of our Civil Practice Act, which authorizes such an action “ by any person in possession, by himself or his tenant, of real property, against any person who claims an estate or interest therein adverse to him, for the purpose of determining such adverse claim, estate or interest.” C. L. Utah, p. 477, § 479.
The complaint alleges that plaintiff is the owner of and in possession of a certain described lot of ground in Salt Lake *489City, and that defendants set up an adverse claim to a strip thereof, eight feet front, and running back 214J feet, as an alley way. The answer of defendants denies plaintiff’s ownership and possession of said strip of ground, and as a defense set up a right of private way obtained by conveyance from "Walker Brothers; and, as a further defense, claims that in 1858, the predecessors in interest of said plaintiff, as owner of said lot, dedicated the strip of ground to public use as an alley way.
Upon the trial in the court below, when the plaintiff had introduced his evidence and rested, he was, upon motion of the defendant, non-suited, and thereupon he has appealed to this court.
In order to determine whether or not the court below erred in non-suiting the appellant, it is necessary to ascertain what is required of a plaintiff to maintain such statutory action, and to see whether the appellant’s allegations and proofs brought him within the requirements.
The statute prescribes that the action may be brought “ by any person in possession, by himself or tenant.” But whether this “in possession” applies to the whole of a tract, or only to such part thereof as may be in dispute, is left entirely to interpretation.
The old doctrine was that a party having the title to a whole tract, and being in actual possession of a part thereof, there being no adverse possession of any portion of it, was held to be in possession of the whole tract. We believe that this doctrine is fully recognized in the books and by the courts, and we do not think that any case to which our attention has been called contravenes it. The case of Sepulveda v. Sepulveda 39 Cal. 13, is referred to by both appellant and respondents, as one in which the true rule was laid down. It was, however, not a case like the one at bar, yet it fully recognized the correct rule in its dieta. It was a case in which the plaintiff was not in actual possession of any part of the tract of land claimed, and the court declared that there must be an actual possession, but it did not say that the plaintiff must be *490in actual occupancy of the whole tract. It in express terms rejects such an interpretation of the law¿ and says: “We do not mean to be understood as holding now that where a pos-sessio pedis of a portion of an entire tract of land is established in a party, he might not, in such an action as this, resort to the title deeds for the purpose of extending that possession to the outer boundaries of the tract, as against the defendant, where no adverse possession in any part of the entire tract appeared.”
This same doctrine is afterwards recognized in the case of Coleman v. Turnpike Co., 49 Cal. 517.
Let us apply the rule to the case at bar. The appellant showed a fee-simple title to the whole tract or lot of ground, including the strip in dispute. The complaint alleged possession of the whole lot in the appellant, and the answer does not deny such possession, except as to the strip in question. The respondents do not claim, nor does the proof show them, to be in possession of any part of the lot. The evidence disclosed the fact that buildings occupied by the appellant covered nearly the whole of the lot, excepting the alley way, and that his improvements extended into the alley in the extreme rear, and that he had put a gate across the alley. The gate, however, did not remain beyond four or five days, having been cut down by respondent Taylor.
The pleadings and evidence together show that the alley way was left by appellant and his grantees for the use and convenience of the occupants of his buildings, but the same had been used by respondents in going into and out of their property, which bordered upon the alley way.
As, therefore, the appellant was at least occupying a large part of said lot, with title to the whole of it, including the alley way, and there was no adverse occupant of any part thereof, we consider that appellant’s possession of the alley way was fully sufficient, so far as the question of possession goes, to authorize this action under the 254th section of our Civil Practice Act.
*491But it is urged that tbe appellant could not recover, unless he should show that respondents’ claim was a cloud upon his title; that it was apparently valid but in fact invalid. We do not deem this to be a correct conception of the law that should govern in such cases. This is not the old chancery suit to remove a cloiid from the title, nor is it controlled by all the rules that govern in such eases. It is a new and purely statutory right of action.
The respondents and appellant refer with equal earnestness to Head v. Fordyce, 17 Cal. 149, as being a case in which the true doctrine is announced. The court in that case says: “ The statute giving this right of action to the party in possession, does not confine the remedy to the case of an adverse claimant setting up a legal title or even an equitable title, but the act intended' to embrace every description of claim whereby the plaintiff might be deprived of the property, or its ' title clouded, or its value depreciated, or whereby the plaintiff might be incommoded or damnified by the assertion of an outstanding title already held or to grow out of the adverse pretension. The plaintiff has a right to be quieted in his title whenever any claim is made to real estate of which he is in possession, the effect of which claim might be litigation or a loss to him of the property.” This doctrine is approved in Horn v. Jones, 28 Cal. 194; Joyce v. McAvoy, 31 Cal. 287; Lich v. Ray, 43 Cal. 83, and in Stoddard v. Burge, 53 Cal. 394.
The words “ claims on estate or interest ” are used in a broad sense, and are not technical in their meaning, and were evidently intended to embrace every species of adverse claim set up by a party out of possession whereby the plaintiff’s enjoyment of his property may be interfered with.
It is further urged that it devolved upon the appellant to prove the invalidity of the respondents’ adverse claim. This is not contemplated by the statute, but the rule whieh governs in other cases governs in this, that wherever the defendant asserts an affirmative defense it devolves upon him to prove it. *492Proof of possession by plaintiff is sufficient in the first instance, under section 254 of our Civil Practice Act. Horn v. Jones, 28 Cal. 198; Scorpion S. M. Co. v. Marsano, 10 Nev. 370; Crook v. Forsyth, 30 Cal. 662.
It is not necessary for us to pass upon the question as to want of findings, as the case is disposed of by the rulings upon the other points. We would suggest, however, that our statute and that of California are' not identical, and that the rule in this Territory, therefore, might vary from that in the State referred to.
The judgment of the court below is reversed, with costs, and the district court directed to overrule the motion of respondents for non-suit of appellant.
