This is an action to quiet plaintiffs’ title to certain waters of the main fork of Greenhorn Creek in Siskiyou County, and of certain tributaries of said creek called Heybrook Gulch and Barker Gulch, and to have the relative and proportionate rights of the plaintiffs and defendants to such waters judicially determined and declared. The •case was tried without a jury and judgment was rendered in favor of defendants. Plaintiffs appealed from the judgment and from an order denying their motion for a new trial.

The plaintiffs are the owners of a water-ditch called the Cornish & Company ditch, which has its head in the main Greenhorn Creek, and runs on the northerly side of the creek down and across to the north fork of said creek, where the water that is carried by the ditch to said north fork is used by plaintiffs for mining purposes. Defendants are the owners of a placer mining claim called the Clark & Company claim, which is situated in the bed of the main fork of Greenhorn Creek, and over this mining claim passes the said Cornish & Company ditch. This ditch before reaching defendants’ mining claims passes across the said two tributaries of Greenhorn Creek and carries their waters, as well as the water of the main creek, to defendants’ mining claim. Defendants concede that plaintiffs have the right to carry over and across their mining claim all the waters flowing in this ditch during the night-time-—that is, from six o’clock p. m. to six o’clock A. m. of the next day; but they aver that defendants have the right to use upon their mining claim all the water flowing in said ditch during the daytime—that is, from six o’clock A. M. to six o’clock p. m. of each day—and deny that plaintiffs have any right to the use of any such water during the hours last above mentioned. The plaintiffs in their amended complaint admit that they have no right to the water of the main Greenhorn Creek during the daytime, but they aver that during all of the time, both night and day, they have the right to carry away in the ditch across and over defendants’ mining claim all the water which flows in the ditch from the said two gulches. And so the real controversy between the parties concerns only the waters of said Heybrook and Barker gulches.

The defendants in their answer pleaded as an estoppel against plaintiffs a certain prior judgment rendered in the superior court in a case entitled Maurice Renner, as Trustee, v. Joseph Azevedo et al., contending that the judgment in that case determines the rights of plaintiffs in the case at bar to the water in contest to be only those here admitted by defendants, and that plaintiffs are estopped by said judgment from contending otherwise. When, at the trial, defendants offered in evidence the judgment-roll in the Renner case, its introduction was objected to by plaintiffs and the objection was overruled and the judgment-roll admitted; and to the ruling plaintiffs excepted. Whether or not that judgment-roll was properly admitted is the main question on this appeal and the only one calling for special notice; and it seems to be quite clear that its admission in evidence was an error. A judgment cannot operate as an estoppel except where it is given in a cause between the same parties or their privies. (See Boggs v. Ciarle, 37 Cal. 236 .) In the case at bar there is some evidence tending to show that the plaintiffs, or at least some of them, acquired their interests in the ditch and water from the1 plaintiff in the Renner v. Azevedo matter, and-it may be conceded for present purposes that plaintiffs, are the successors in interest of said Renner; but there is no relation or connection whatever, with respect to the property rights here involved, between the defendants in the case at' bar and the defendants in the former case. The defendants here are in no position to assert or invoke any right which might have been declared in the former action as between the parties hereto; they are neither the parties nor privies of parties to that action. That the errror in admitting the judgment-roll was prejudicial is clear; for there was some testimony tending to establish plaintiffs’ contention that they are entitled to the use of the water in contest to the extent asserted by them, and we cannot say how the court would have found as to that contention if it had not admitted the judgment-roll in the Renner case and given it the significance of an estoppel. For this error the case must be reversed.

Plaintiffs offered in evidence the judgment-roll in another case entitled Cardoza v. Hawkins, but defendants’ objection to it was sustained. That ruling was right. There was the same lacking here of the relation of parties and privies that appeared in Renner v. Azevedo.

We see no other points calling for discussion.

The judgment and order appealed from are reversed.
