Custom Unlimited, David Navratil, and Ramona Pabian appeal the money judgment entered by the district court for Buffalo County in favor of The Ravenna Bank. We reverse and remand for further proceedings.
Ravenna Bank brought a law action against Custom Unlimited, a partnership composed of Navratil and Pabian, and against Navratil and Pabian as individuals. In the first part *542 of its petition, paragraphs I to IV, Ravenna Bank alleged that Custom Unlimited, by Navratil and Pabian as partners of Custom Unlimited, had given the bank a promissory note on which Custom Unlimited was in default and owed $29,116.95 in principal and interest. The promissory note was dated January 18, 1983. In the second part of its petition, paragraph V, the bank alleged that, on May 27, 1980, Navratil and Pabian, as individuals, had given their “unlimited continuing guaranty” concerning Custom Unlimited’s promissory note. Ravenna Bank prayed for “judgment against the defendants and each of them in the sum of $29,116.95.” To the bank’s petition, Custom Unlimited, Navratil, and Pabian demurred, alleging an improper joinder of causes of action. See Neb. Rev. Stat. § 25-806 (Reissue 1985). When the court overruled the defendants’ demurrer, the defendants filed their answer but failed to assert their objection to the causes of action joined in the bank’s petition. At the pretrial conference the district court authorized the defendants to “supplement the answer by preserving the demurrer previously filed and ruled upon.” The defendants, on the morning of trial, filed a separate pleading entitled “Demurrer,” alleging that the defendants did “preserve their Demurrer previously filed herein.” At commencement of the bench trial, in open court counsel for the defendants called the court’s attention to the demurrer just filed and again referred to a misjoinder of the bank’s causes of action, that is, the action on the partnership promissory note joined with the action on the guaranty of that promissory note. In reference to the recently filed or second demurrer, the court responded: “I think we’ve already addressed it. I overruled it. We’ll consider your demurrer as part of your answer. You may proceed.” Without Ravenna Bank’s objection to including the demurrer as an issue to be resolved, trial continued to the conclusion of evidence, when the district court entered judgment that there was “due to the plaintiff from the defendants on the cause of action as set forth in plaintiff’s petition . . . the sum of $23,000.25.” (Emphasis supplied.)
Custom Unlimited, Navratil, and Pabian contend their demurrer should have been sustained and separate trials ordered regarding the promissory note and guaranty. Ravenna *543 Bank counters that the defendants failed to preserve their demurrer and, having waived their demurrer, cannot question the district court’s disposition of the demurrer.
We first consider whether the defendants have preserved the district court’s ruling on their demurrer as a matter for appellate review. Under § 25-806 a defendant may demur to the petition “when it appears on its face . . . several causes of action are improperly joined.” When a misjoinder does not “appear upon the face of the petition, the objection may be taken by answer, and if no objection be taken either by demurrer or answer, the defendant shall be deemed to have waived the same.” Neb. Rev. Stat. § 25-808 (Reissue 1985). Where a defendant suffers an adverse ruling on a demurrer based on misjoinder of causes of action and proceeds to trial on the answer which does not reassert the issue of misjoinder, there is no question preserved for appellate review concerning joinder of causes of action, because the defendant has waived any error in the trial court’s ruling on the demurrer alleging misjoinder of causes of action. See,
Ivins v. Ivins,
We now proceed to the defendants’ contention that joinder of the cause of action on the promissory note with the cause of action on the guaranty constitutes reversible error.
Neb. Rev. Stat. § 25-701 (Reissue 1985) provides in pertinent part as follows: “The plaintiff may unite several causes of action in the petition, whether they be such as have heretofore been denominated legal or equitable, or both, when they are included in any of the following classes: ... (2) contracts, express or implied.” Neb. Rev. Stat. § 25-702 (Reissue 1985) *544 states: “Except for product liability actions, the causes of action so united must affect all the parties to the action, and not require different places of trial.” Defendants maintain that the bank’s petition asserts two causes of action which do not “affect all the parties to the action” and, thus, cannot be joined in one petition.
“A cause of action is judicial protection of one’s recognized right or interest, when another, owing a corresponding duty not to invade or violate such right or interest, has caused a breach of that duty.”
Sorensen v. Lower Niobrara Nat. Resources Dist., 221
Neb. 180, 193,
Ravenna Bank’s petition describes two transactions. There is no doubt that one transaction relates to Custom Unlimited’s partnership note, while the second transaction involves the Navratil-Pabian guaranty. As we recently stated in
Chiles, Heider & Co. v. Pawnee Meadows,
While it is true that § 25-701 permits joinder of several causes of action based on contract, § 25-702 imposes a limitation, namely, the actions so united or joined “must affect all the
*545
parties.” Therefore, a petition joining two or more defendants may not assert multiple claims or causes of action unless each alleged claim or cause of action affects all joined defendants. See
Stahmer v. Marsh,
To buttress their argument that there has been an improper joinder of causes of action, the defendants rely primarily upon
Barry
v.
Wachosky,
This court has never overruled the principle promulgated by
Barry.
As expressed in
Schultz
v.
Wise,
Although the bank does not assail the principle adopted in Barry v. Wachosky, supra, Ravenna Bank does seek to distinguish Barry from the present case. According to Ravenna *546 Bank, the promissors and guarantor in Barry were different persons, whereas in the present case the transactions in question “involve the same parties,” and the defendants “are essentially the same people.” Brief for Appellee at 6-7. Such identity, Ravenna Bank argues, authorizes joinder of the two causes of . action because each cause of action affects the same defendants and, therefore, affects “all the parties,” satisfying the requirement of § 25-702.
Ravenna Bank overlooks some fundamental law regarding partnerships. In Nebraska, “A partnership is an association of persons organized as a separate entity to carry on a business for profit.” Neb. Rev. Stat. § 67-306(1) (Reissue 1981). “Under both statutory and case law in Nebraska, a partnership has long been considered as an entity separate and apart from the individual partners. [Citation omitted.] The Uniform Partnership Act adopted in Nebraska clearly mandates the entity theory of partnership. [Citations omitted.]”
State
v.
Siers,
Applying the foregoing law of partnership to the present case, Custom Unlimited’s promissory note was ¿ contract creating a partnership debt owed the bank. The guaranty was a separate undertaking by Navratil and Pabian, individuals distinct from the partnership entity, that is, an agreement to pay Custom Unlimited’s debt on default by that partnership.
The rule adopted in Barry v. Wachosky, supra, applies to the present case and may be restated, for present purposes, as follows: Where one defendant has executed a promissory note in favor of the plaintiff and a different defendant has made a guaranty regarding such promissory note of the other defendant, § 25-702 precludes the plaintiff’s joining the two defendants in one petition containing two causes of action arising from the distinct contracts — the promissory note and corresponding guaranty. In the case before us the bank’s petition contained two causes of action based on different contracts or undertakings and sought to impose liability on different defendants on account of distinct obligations resulting from those separate contracts. Under the circumstances joinder of the two causes of action was improper. *547 The district court should have sustained the demurrer based on misjoinder of causes of action.
Although the district court was incorrect and committed error in allowing joinder of the causes of action in question, we must determine whether such procedural error affected a substantial right of the partnership or guarantors. Absent prejudicial effect on an adverse party’s substantial right, the Supreme Court may disregard a procedural error committed by a trial court. See Neb. Rev. Stat. § 25-853 (Reissue 1985). See, also,
Coomes
v.
Drinkwalter,
When the district court entered judgment “on
the cause of action,”
the fact that the bank’s petition contained two causes of action results in uncertainty concerning the nature and extent of the judgment entered. On examining the judgment rendered, one must question the basis for that judgment. Was the judgment entered on the first cause of action concerning the debt created by the partnership promissory note? Or was the judgment entered on the second cause of action for the guaranty regarding the partnership’s default in payment of its promissory note? The judgment’s effect is imposition of joint and several liability on the partnership and the guarantors without reference to the precise basis for such liability. If judgment has been entered on the first cause of action, the assets of the guarantors are subjected to liability for payment consequent to a contract to which the guarantors were not a party, the partnership promissory note. On the other hand, if judgment has been entered on the cause of action involving the guaranty, the assets of the partnership are subjected to payment for liability accruing under the guaranty, an undertaking or contract to which the partnership was not a party. The matter would be complicated even further if the judgment were construed to apply to Navratil and Pabian as partners in Custom Unlimited. See Neb. Rev. Stat. § 25-316 (Reissue 1985) (necessity of a bill in equity to charge a partner’s individual property for satisfaction of a judgment rendered against the partnership). See, also,
