Carl and Pam Spath appeal from the circuit court’s dismissal of their Petition *349 for Damages, against Gary Norris and Jerry and Rhonda Lindsay, on grounds of res judicata and collateral estoppel. Because the court erred in applying these defenses, we reverse and remand.
I. Factual and Procedural History
Gary Norris was the developer of a subdivision in Brookfield, Missouri, known as Quail Valley. Jerry and Rhonda Lindsay purchased two lots from Norris and built a home. The Spaths purchased both lots and the newly constructed home from the Lindsays in January 1999.
On May 11, 2002, the Spaths experienced a severe drainage problem in their home during a rainstorm. Water accumulated in the basement and created a four-foot deep pool in front of the home. The Spaths sustained damage to their land and their home, including interior structural damage. The drainage problems continued in August 2004, when another rainstorm resulted in flooding and more serious damage to the exterior of the home.
In April 2006, the Spaths filed suit against the City of Brookfield (“City”) for damage allegedly caused by the negligent care and maintenance of the storm water drainage system, including a defective segment of pipe, and the negligent construction of a swale intended to remediate the run-off problem in 2003. (“Spath I ”) Thе City filed a motion to add Norris and the Lindsays as defendants, claiming they were responsible for the damage to the Spaths’ home. The circuit court initially granted the motion, but the new defendants promptly filed mоtions to dismiss contending that they were not necessary parties under Rule 52.04(a)(1). 1 The court agreed and dismissed Norris and the Lind-says, finding:
[The City] does not allege the ‘deformed segment of pipe’ nor the ‘swale’ werе installed or constructed by any of the added parties. Therefore, 52.04(a)(1) does not apply.... This Court can hear this case as between Plaintiff [Spaths] and Defendant [City] and render a Judgment and the operation of that Judgment will not cause any gain or loss to any of the joined defendants....
Spath I thereafter proceeded to trial, during which the court granted a directed verdict in the City’s favor in January 2007.
Four months latеr, the Spaths filed a Petition for Damages against Norris and the Lindsays for breach of contract, breach of implied warranties, and negligence related to the construction and design of the homе, the storm water system, and the streets and curbs in the subdivision, all of which allegedly resulted in the drainage problems and flooding of the home and property. (“Spath II ”) Norris and the Lindsays moved to dismiss, asserting the affirmative defenses of res judicata and collateral estoppel based on Spath I. The circuit court granted the motion and entered judgment dismissing the petition. The Spaths appeal.
II. Analysis
In their sole point on appeal, the Spaths contend the circuit court erroneously applied the law in dismissing their petition on grounds of
res judicata
and collateral estoppel. Because a determination of
res judicata
necessarily depends upon proof of the prior judgment, we review the motion to dismiss under the same standards as a motion for summary judgment. W
EA Crestwood Plaza, L.L.C. v. Flamers Charburgers, Inc.,
A. Res Judicata
The doctrine of
res judicata
operates to bar any claim that was previously litigated between the same parties or those in privity with them.
In re Marriage of Evans,
There is also a rule against splitting a cause of action, which is a form of
res judicata. Shores v. Express Lending Servs., Inc.,
The Spaths contend the court erred in finding them claims in Spath II were barred by the res judicata effect of Spath I because the two cases did not involve the same parties and subject matters. Spath I was filed against the City for negligent maintenance of the public storm water drainage system. Although Norris and the Lindsays were initially joined as defendants in Spath I, the circuit court ultimately dismissed them as parties because they had no control over the maintenance or repair of public property. Spath II was filed against Norris and Lindsay and alleged breach of contract theories and negligence in the design and construction of the home and drainage system in the subdivision. We agree that there were different defendants in the two lawsuits and different subject matters, in that Spath I addressed the maintenance of the public storm water system while Spath II dealt with the design and construction of private and public property.
Norris argues that he was in рrivity with the City based on its approval of his development plans for the Quail Valley subdivision. He therefore asserts that the directed verdict in favor of the City in
Spath I
was determinative of the claims against him in
Spath II.
As noted, however, the only claims against the City in
Spath I
were for negligent
maintenance
of the public storm water system and not for the design аnd construction that occurred during the development phase. Norris had no role in the City’s obligation to maintain public property and could not be sued for failing to do so. “Privity, as a basis for satisfying the ‘samе party’ requirement of
res judicata,
is premised on the proposition that the interests of the party and non-party are so closely intertwined that the non-party can fairly be considered to have had his or her day in court.”
Stine v. Warford,
*351
The Spaths could have brought their damage claims against all of the defendants in a single lawsuit, but we find no authority that required them to do so. “When two defendants аre potentially liable for the same loss, the claims are considered separate and two suits can be maintained against the differing parties.”
Hollida,
When a person suffers injury as the result of the concurrent or consecutive acts of two or more persons, he has a claim against each of them. If he brings an action against one of them, he is required to present all the evidence and theories of recovery that might be advanced in support of the claim against that obligor .... If he recovers judgment, his claim is “merged” in the judgment so that he may not bring another action on the claim against the obligor whom he has sued.... Correlatively, if judgment is rendered against him, he is barred from bringing a subsequent action against the obligor.... But the claim against others who are liable for the samе harm is regarded as separate. Accordingly, a judgment for or against one obligor does not result in merger or bar of the claim that the injured party may have against another obligor.
Hollida,
The harm may be the same in Spath I and Spath II — i.e. damage tо the Spaths’ home resulting from defective drainage systems — but it was caused by different parties, challenged under different legal theories, and required proof of different facts against the defendants. In light of thеse circumstances showing a lack of common identity, the circuit court improperly applied the doctrine of res judicata to bar the claims in Spath II.
B. Collateral Estoppel
Collateral estoppel, or issue preclusion, bars relitigation of issues that were necessarily and unambiguously decided in a prior proceeding.
Shores,
Unlike
res judicata,
collateral estoppel applies to issuеs that are being relitigated even though the prior lawsuit raised a different cause of action.
Shores,
Based on the pleadings, we find no basis for collateral estoppel in this case because *352 the issues presented are factually distinct from those in the prior litigation. Polley, 2 S.W.3d at 894. The City was sued in Spath I for negligent maintenance of the drainage system and other repair efforts, which occurrеd subsequent to the original construction. In Spath II, Norris and the Lindsays are being sued for breach of contract and warranties associated with the negligent design and construction of the dwelling, foundation, grading, drainagе system, streets, and curbs. Clearly, the issues are not identical.
Nevertheless, we acknowledge the possibility that some of the facts decided in
Spath I
may be relevant to the issues in
Spath II
and binding upon the Spaths. “ ‘The nature of collateral estoppеl is that a fact appropriately determined in one lawsuit is given effect in another lawsuit involving different issues.’ ”
Shores,
Conclusion
The judgment is reversed, and the cause is remanded to the circuit court for further proceedings consistent with this opinion.
All concur.
