Mr. Justice Wolverton,
after stating the facts in the above terms, delivered the opinion of the court.
1. The sole question presented for our consideration is whether the circuit court erred in denying defendant’s motion to open up the default, and leave to file an answer to the merits. The application com.es within the first, rather than the last, clause of Section 103, B. & C. Comp., the purpose of the defendant being to be relieved of a default in failing to answer, and to be allowed to answer after the time limited by the Code, and not to be relieved of a decree entered against him through his mistake, inadvertence, surprise, or excusable neglect. The decree formerly rendered had been vacated on the appeal, and nothing remained in the record but an entry of default against the defendant, and the purpose of the motion was to get rid of this, and to he allowed to answer to the merits after the time for answering had expired. The case is not *363widely different from that where simple default, not a judgment or decree, has been entered against a party who has failed to appear when served with a summons, and he applies to be let in to answer to the merits, the defendant here occupying the more pardonable position. Ordinarily, if he presents reasonable grounds excusing his default, the courts are liberal in granting relief, for the policy of the law is to afford a trial upon the merits when it can be done without doing violence to the statute and established rules of practice that have grown up promotive of the regular disposition of litigation. It was the purpose of counsel, by adopting the course pursued, to present two questions: (1) That the court had no jurisdiction of the person because of the supposed defect in the service of summons in the original cause, consequently that it could have no jurisdiction in the supplementary proceeding, such proceeding being based largely upon the hypothesis that a valid decree of divorce had been previously rendered ; and (2) that the court did not have jurisdiction to grant the particular relief demanded. In doing this it is further manifest that they desired to avoid any adverse effect that a general appearance might have had, either in the original or supplementary cause, in conferring jurisdiction of the person or of the subject-matter. There was at the time of entering the special appearance a judgment of department No. 1 of the circuit court of Marion County in their favor upon the first question, although subsequently reversed (McFarlane v. Cornelius, 43 Or. 513" court="Or." date_filed="1903-07-27" href="https://app.midpage.ai/document/mcfarlane-v-cornelius-6899379?utm_source=webapp" opinion_id="6899379">43 Or. 513, 73 P. 375" court="Wash." date_filed="1903-07-20" href="https://app.midpage.ai/document/state-v-tieman-4725849?utm_source=webapp" opinion_id="4725849">73 Pac. 375, 74 Pac. 468), and as to the second they were successful in part upon the appeal. It is apparent, therefore, that counsel were acting in good faith, according to their best judgment, and they were not without plausible reason for resisting a general appearance. It was not an insuperable barrier to excusing their defaull that they were unsuccessful in maintaining their position to the *364fullest extent, while, upon the other hand, the fact that they were successful in part affords persuavive and fair argument why they should be relieved. Counsel have a legal right to present their causes upon grounds of their own choosing, and to employ all fair and honorable tactics and strategy to bring them to a successful issue. By tactics and strategy we do not mean trickery or deception, or the adoption of a,ny measures calculated to defraud or overreach the adversary, and thereby to thwart or pervert justice; but rather their privilege to call to their aid all recognized rules of law and practice most advantageous to the maintenance of their course. That they may at times mistake the law, the rules of practice, or the application of either, is not to the purpose, for, if counsel were always right, and always agreed upon such matters, there would be but little use for courts of justice, except -as triers of fact. When, however, they have acted conscientiously, and in perfect good faith, in the course pursued toward the court and the opposing parties litigant, and have reasonable grounds upon which to base their judgment, it does not stand to reason that they or their clients should be punished or suffer because it subsequently develops by judgment of the court that they were mistaken in their views of the law and the proper procedure to be adopted.
2. Now, without pursuing the matter further, it is insisted that, because counsel were mistaken as a matter of law, the court ought not to relieve defendant of his default. Every time, however, a demurrer is filed and overruled, there is an apparent mistake on the part of counsel as a matter of law; yet, if interposed in good faith, courts do not hesitate to grant leave to answer. Indeed, such is the law’s behest (B. & C. Comp. § 101), and the statute under which the present relief is sought is strongly akin to that. The delay here was necessarily larger than in *365such a case, but that circumstance does not detract from the force of the argument, as the course pursued was apparently the only safe method at the command of counsel by which to save all the questions desired to be presented for adjudication. The defendant has a meritorious defense, and we are called upon to determine whether there was an abuse of discretion in the trial court in denying his motion. The discretion accorded is one governed and controlled by legal principles — “a legal discretion,” as was said in Thompson v. Connell, 31 Or. 231" court="Or." date_filed="1897-04-19" href="https://app.midpage.ai/document/thompson-v-connell-6897387?utm_source=webapp" opinion_id="6897387">31 Or. 231, 235 (48 Pac. 467, 65 Am. St. Rep. 818), “to be exercised in conformhy with the spirit of the law, and in a manner to subserve, and not to defeat, the ends of substantial justice.”
3. Taking into account the viewpoint of counsel, acting honestly and from conscientious motives, as it is very apparent they did, that the course pursued was the only way by which questions deemed vital to their defense could be most effectively presented, and their right to have the law finally determined upon the theory adopted, it not being trivial or frivolous, and there being plausible reason and authority for its support, we are of the opinion that the motion ought to have been granted, and that there was error in the exercise of the legal discretion accorded to the court in such matters in denying it. In support of these views and the conclusions here reached, see Baxter v. Chute, 50 Minn. 154 (52 N.W. 379" court="Minn." date_filed="1892-06-13" href="https://app.midpage.ai/document/baxter-v-chute-7967483?utm_source=webapp" opinion_id="7967483">52 N. W. 379, 36 Am. St. Rep. 633); Whereatt v. Ellis, 70 Wis. 207, 35 N. W. 314, 5 Am. St. Rep. 164).
The decree of the trial court will therefore be reversed, and the cause remanded, with directions to allow the motion to set aside the default of defendant in the supplementary proceeding, with leave to file his answer tendered to the merits, and for such, other proceedings as may seem proper. Reversed.
