¶1Plaintiff, the owner and holder of two tax sale certificates issued upon judgment and sale bad under and by virtue of chapter 51, Laws 1901, known as the “Scavenger Tax Law,” claiming that his title had become perfected through the expiration of the period for redemption, brought this action to quiet his title in and to the land covered by such certificate. Among the parties made defendants in said action were Emmett *371E. Beatty and Charles G. Juliand, the. owners of the fee title to said land, unless their title had been cut off by the certificates held by plaintiff. These defendants being nonresidents, an order for publication of summons was procured; the summons was published; and immediately after the last publication of summons, and long before the expiration of the 30-day period that must elapse after the completed service before defendants can be in default, plaintiff applied fi> the court for and procured a default judgment herein against all of the defendants. No notice of lis pendens was filed at the time of the commencement of the action. Soon after the • commencement of such action and before the default judgment was entered therein -the defendant Emmet LBeattv conveyed his interest in and to said land to one Sarah J. Henry. Several months after the entry of the default judgment, plaintiff asked for and procured an order allowing an amendment of the summons and complaint by adding as a party defendant the said Sarah J. Henry. Such amended summons and complaint were served upon the said Sarah J. Henry. As amended, the complaint in no manner referred to the judgment that had been rendered in such action. Defendants Henry and Juliand thereafter served and filed answers therein, claiming to hold fee-simple title in and to said land. Service of these answers was admitted by plaintiff. To such answers the plaintiff replied and pleaded the default judgment in bar of any claim by defendants. Upon the issues so raised, the cause was tried to the court without a jury; findings of fact and conclusions of law were entered in favor of the plaintiff; and, upon such findings and conclusions, judgment entered. A motion for a new trial having been denied, the two defendants, Henry and Juliand, appealed from the judgment and order denying a new trial. After the taking of such appeal, John B. Henry having acquired whátever interest Sarah J. Henry had in and to the lands in question, he was, by proper order, substituted as 'a party in the place of said Sarah J. Henry.
¶2Among the points raised by appellants and saved by proper assignments of error was the question of the sufficiency of the notice of expiration of the period for redemption from the certificates held by plaintiff and of the proof of service of such notice. It will be unnecessary for us to discuss the defects in such notice and proof of service, inasmuch as the said proof of .service comes *372directly under the rulings of this court in the case of Sandys v. Robinson et al., 26 S. D. 281, 128 N. W. 484, and such proof is, for the reasons therein stated, fatally defective. Respondent, in his brief, does not attempt to sustain the validity of the tax title, but relies wholly upon the proposition that appellants “are precluded by the default judgment entered herein from assailing these [tax sale] proceedings.”

¶4The settled record and the abstract were changed prior to the filing of respondent’s brief. Such brief ignores the question of the validity of respondent’s tax title and bases respondent’s cause upon the sole proposition that the default judgment stands as res adjudicata.
¶5These facts stand forth undisputed herein: The trial court recognized the answers interposed by the defendants' Henry and Juliand; it admitted proof in support of the issues raised by the complaint and such answers; it made findings u'pon all such issues against all of the 'defendants; and it entered an entirely new judgment against each and every one of the defendants named in the original judgment, as well as against Sarah J. Henry, which judgment recites the action was tried as against Sarah J. Henry “upon the issues joined by the amended complaint and the answer of the defendant Sarah J. Henry.” From the above we think that, regardless of the ruling entered denying the motion of the defendants Henry and Juliand, asking that the trial court allow them to answer and defend, it clearly appears that the trial court treated the default judgment as'no bar to a defense on the part of defendant Henry. Did not the court, by the course it pursued, virtually open up the default judgment as against both these defendants? There can be no question but what a refusal to allow these defendants to defend upon the merits would have been a rank abuse of judicial discretion under the undisputed facts of this case.

¶8The case of Watson v. Harris, supra, is very similar to the case at bar in many respects, and in -that case the court said: “It is apparent from this' statement of the case, that while no formal order appears to have been entered setting aside the judgment by default, either as to Carr or Watson, they were each allowed to jilead to the action. Not only so, but they were allowed to introduce testimony to defeat plaintiff’s recovery. They were as much before the court upon the hearing of the cause as any of the other defendants; as much so, in fact, a's if the court had formally set aside the default and allowed them to- plead and introduce evidence. … A defendant against whom a judgment by default stands has no right to plead in the cause or to introduce evidence ■to defeat the plaintiff’s action.”
¶9In the case at bar both defendants Henry and Juliand were permitted, without objection by court or plaintiff, to plead to the merits of the action. They were permitted to introduce testimony tending to defeat plaintiff’s tax title. The court, in its findings, passed upon the issues raised by their answers and considered the evidence introduced by them -to defeat plaintiff’s claim of title; in fact, the court made no- direct findings of fact upon anything other than the issues so raised-by the answers -of these two defendants, which issues covered the merits herein. _ The court and plaintiff, without objection, permitted these defendants to do the very things they could have done had the court made a formal order vacating said default judgment, and the things they could not have properly done without a vacation of such judgment. The court treated *376the proceedings in the case, with reference to the trial of the rights of these defendants, under their said answers, just the same in all respects as if the default judgment had in fact been set aside by formal order; these defendants had no right to plead or offer testimony as to plaintiff’s tax title while the default judgment existed. There was an indirect vacation of said, default judgment, such as precludes said judgment from being considered against the answering defendants as barring or cutting off their right to be heard upon the merits. The question of res judicata is therefore not in this case. This case should therefore be decided upon the merits as to the sufficiency of the evidence to sustain plaintiff’s tax title; that being the only question brought by appellants before this court for review.
¶10The judgment and order appealed from are reversed, and the trial court is directed to proceed in accordance with the views announced herein.
