LAURA DENVIR STITCH, Judge.

The Manitowoc Company Inc. appeals the trial court's dismissal with prejudice of Manitowoc's claims for contribution or indemnity against United States Steel Corporation due to Manitowoc's failure to admit its own fault in its third-party petition against U.S. Steel. Manitowoc argues that it was not required to admit fault to seek either contribution or indemnity but rather could plead that if it was liable to the plaintiff, then U.S. Steel was liable in full or in part to Manitowoc.

This Court reverses. U.S. Steel was incorrect in arguing below and in this Court that a failure to admit fault in the third-party petition for contribution deprives the trial court of jurisdiction or requires a dismissal on the merits of the underlying right to obtain contribution, as opposed to being a mere procedural error. Even were dismissal proper in the absence of an admission of fault, it should have been without prejudice.

Even more basically, however, neither public policy nor this Court's rules and decisions governing third-party pleading require a party to admit its own fault to proceed on a third-party claim, and this Court affirmatively holds that such an admission is not required. To the extent that Stephenson v. McClure, 606 S.W.2d 208 (Mo.App.1980), and cases following it1 require a third-party petition to contain an admission of fault and to the extent they suggest that this Court's decision in Mo. Pac. R.R. v. Whitehead & Kales Co., 566 S.W.2d 466 (Mo. banc 1978), so requires, they are overruled. For all these reasons, the trial court erred in dismissing the petition. The case is remanded.

I. STATEMENT OF FACTS

In January 2006, the boom on a construction crane that was owned and operated by Jacobsmeyer-Mauldin Construction Company fell and landed on a building at Washington University, damaging both the building and the crane. A subsequent investigation concluded that the accident was caused by the failure of the crane's main lift cylinder. Grove U.S. LLC designed, manufactured and sold the crane, allegedly using the steel or steel cylinder provided by U.S. Steel. Grove is a subsidiary of Manitowoc.

At the time of the accident, Jacobsmeyer was insured by Travelers Property Casualty Company of America. Travelers paid Jacobsmeyer's insurance claims associated with the accident and reached a settlement agreement with Grove under which Grove agreed to pay Jacobsmeyer and Travelers (hereinafter referred to collectively as "Jacobsmeyer") for a majority of their remaining losses associated with the accident. Grove failed to make any of the payments called for in the settlement agreement. In November 2009, Jacobsmeyer, therefore, sued both Grove and its parent Manitowoc (hereinafter referred to jointly as "Manitowoc") for breach of the settlement agreement.2

Manitowoc filed an answer denying liability and, in January 2010, filed a third-party petition asserting claims for contribution and/or indemnity against U.S. Steel, arguing that U.S. Steel's predecessor-in-interest provided the faulty steel or steel cylinder for the crane. Manitowoc asserted in the petition that if the trier of fact found it liable to Jacobsmeyer, then Manitowoc was entitled to contribution or indemnity from U.S. Steel because any damages caused by the accident resulted from U.S. Steel's fault in providing defective materials for the crane.

U.S. Steel filed a motion to dismiss Manitowoc's third-party petition, arguing it failed to satisfy pleading requirements because Manitowoc did not admit its own liability as a joint tortfeasor in its third-party petition. The trial court dismissed Manitowoc's third-party petition with prejudice. Manitowoc appealed. After an opinion by the court of appeals, this Court granted transfer pursuant to art. V, sec. 10 of the Missouri Constitution.

II. STANDARD OF REVIEW

This Court reviews the grant of a motion to dismiss de novo. City of Lake Saint Louis v. City of O'Fallon, 324 S.W.3d 756, 759 (Mo. banc 2010). This Court "will consider only the grounds raised in the motion to dismiss in reviewing the propriety of the trial court's dismissal of a petition, and in so doing, it will not consider matters outside the pleadings." Id. Additionally, review of a motion to dismiss for failure to state a cause of action "is solely a test of the adequacy of the ... petition." Id. This Court will review the third-party petition "in an almost academic manner, to determine if the facts alleged meet the elements of a recognized cause of action, or of a cause that might be adopted in that case." Id.

III. A THIRD-PARTY PLAINTIFF NEED NOT ADMIT FAULT IN A THIRD-PARTY PETITION FOR CONTRIBUTION OR INDEMNITY

Manitowoc argues that the trial court erred in dismissing its petition with prejudice and asserts that a third-party plaintiff is not required to admit fault in its third-party petition. Manitowoc asserts that Rule 55.10 permitted it to deny liability in its answer while also pleading in its third-party petition that if it is liable to Jacobsmeyer, then third-party defendant U.S. Steel is liable to Manitowoc. Manitowoc alternatively asserts that even if dismissal were proper, the dismissal should have been without prejudice. U.S. Steel argues that Manitowoc was required by Rule 52.11(a), governing third-party practice, to admit its own fault, that its failure to do so should be considered either a jurisdictional error or a ruling against the merits of the third-party petition, and that, therefore, dismissal should be with prejudice.

First, nothing in Rule 52.11 suggests that inadequacies of a third-party pleading constitute a jurisdictional defect or that a failure to follow its requirements should be treated as ruling on the merits of the third-party claim. Rather, Rule 52.11(a) provides that:

In other words, Rule 52.11 provides the procedural mechanism for determining whether and how to try third-party claims once the court has jurisdiction over the parties. Rule 52.11 sets forth procedures that the court and parties are to follow; it does not purport to add additional jurisdictional requirements to those set out in the Missouri Constitution. J.C.W. ex rel. Webb v. Wyciskalla, 275 S.W.3d 249 (Mo. banc 2009) ("jurisdiction of Missouri's courts is governed directly by the state's constitution").

If a party fails to comply with Rule 52.11's procedural requirements, striking the third-party petition may be proper, but nothing in the rule suggests, nor could it properly do so, that such a procedural failure is jurisdictional. And, if the dismissal is for procedural reasons rather than for failure to state a substantive claim on which relief can be granted, then ipso facto it cannot be a dismissal on the merits of the substantive claim. The trial court erred in dismissing the third-party petition with prejudice.

Second, an admission of fault is not required in a third-party petition. Rule 55.10 does not expressly require an admission of fault by a defendant or third-party plaintiff. It states:

Id. Neither does the relevant portion of Rule 52.11(a) appear to require a party seeking contribution to admit its own fault in its third-party petition; the rule states:

Rule 52.11(a).

U.S. Steel nonetheless argues that court of appeals cases have read into third-party practice a requirement that a third-party plaintiff seeking contribution from an alleged joint tortfeasor must admit its fault to the plaintiff to seek contribution from a third-party defendant, citing Stephenson v. McClure, 606 S.W.2d 208 (Mo.App.1980), and Mid-Continent News Co. v. Ford Motor Co., 671 S.W.2d 796 (Mo.App.1984).

Stephenson, Mid-Continent News Co. and similar cases do hold that a party seeking contribution must admit its own fault in its third-party petition to join an alleged joint tortfeasor as a third-party defendant and that a failure to admit one's own fault means that the third-party petition must be dismissed. These holdings do not support dismissal of Manitowoc's third-party claim, however.

As U.S. Steel acknowledges, Stephenson and Mid-Continent are court of appeals opinions. They do not bind this Court, which never has addressed the issue whether a third-party plaintiff must admit its own fault to seek contribution from a joint tortfeasor. Nonetheless, U.S. Steel argues that both Stephenson and Mid-Continent based their holdings that an admission of fault by a third-party plaintiff is required by this Court's reasoning in adopting comparative fault in Mo. Pac. R.R. v. Whitehead & Kales, 566 S.W.2d 466 (Mo. banc 1978),3 and asks that this Court now explicitly so state.

U.S. Steel overreads this Court's decision in Whitehead & Kales. Prior to Whitehead & Kales, a defendant could not bring a third-party claim for contribution against a concurrent tortfeasor. It could bring a third-party claim for indemnity in circumstances such as when the defendant/third-party plaintiff's negligence was passive and the third-party defendant's negligence was active. See, e.g., Crouch v. Tourtelot, 350 S.W.2d 799 (Mo. banc 1961). This meant that, if plaintiff chose not to sue more than one of two or more potential joint or concurrent tortfeasors, the sued defendant could not bring a third-party claim for contribution against these potential concurrent tortfeasors.

To encourage efficiency in the courts, Whitehead & Kales changed this prohibition and permitted cross-claims and third-party claims against all alleged tortfeasors, regardless of whether they were sued by the plaintiff or whether they were passively or actively negligent or sued for indemnity or contribution, stating:

Whitehead & Kales, 566 S.W.2d at 474 (emphasis added).

Whitehead & Kales thereby explicitly says that the same pleading rules "would apply whether the tortfeasors were joined as defendants by the plaintiff or a third party defendant was added to a cause under our rule 52.11." Id. at 474. That is, third-party defendants are to be treated the same as defendants joined by the plaintiff. Under this modified approach, this Court said, this meant that "Concurrent or joint tortfeasors not sued by plaintiff... may now be brought in by third-party practice for a determination in due course of their relative part of the responsibility." Id. (emphasis added). As is the case for cross-claims against defendants joined by the plaintiff in the original action, to recover contribution a third-party plaintiff must "in due course" show that the third-party defendant shares a relative part of responsibility for the tort. But nothing in this or any other portion of Whitehead & Kales requires a third-party plaintiff to admit its own fault in its third-party petition rather than merely alleging that, if it is liable to plaintiff, then the third-party defendant is liable to the third-party plaintiff. Since the decision in Whitehead & Kales, no Missouri case is cited as requiring a defendant to admit its own fault to bring a cross-claim against its co-defendant(s). Neither is this required of a third-party plaintiff under Whitehead & Kales.

This makes sense, for the purpose of third-party practice is "to avoid two actions which should be tried together to save the time and cost of a reduplication of evidence[,] to obtain consistent results from identical or similar evidence and to accomplish ultimate justice for all concerned with economy of litigation and without prejudice to the rights of another." Stemley v. Downtown Medical Bldg., Inc., 762 S.W.2d 43, 47 (Mo. banc 1988). The purpose, therefore, is to allow all claims to be brought in a single action in an effort to avoid multiple actions when separate actions are not necessary and to avoid inconsistent outcomes resulting from separate actions. Nothing in this purpose, in Rule 52.11(a) or in Whitehead & Kales requires the third-party plaintiff to admit fault in its petition. Rather, all that is required "[t]o maintain an action for contribution, [is that] both the party seeking contribution and the defendant against whom contribution is sought must be ... tortfeasor[s], originally liable to the plaintiff-injured party." Gramex Corp. v. Green Supply, Inc., 89 S.W.3d 432, 442 (Mo. banc 2002).

For the foregoing reasons, a third-party plaintiff is not required to admit its fault in its third-party petition. The third-party plaintiff instead can deny liability in its answer to the plaintiff's claim and plead in its third-party petition that, if it is liable to the plaintiff, then the third-party defendant is liable to the third-party plaintiff, exactly as required by the language of Rule 52.11. To the extent that Stephenson, Mid-Continent and similar cases suggest otherwise, they are overruled. Here, the trial court erred in dismissing Manitowoc's third-party petition.4

U.S. Steel argues that the issues in the third-party petition are so distinct from the ones that will be addressed during Jacobsmeyer's breach of settlement action that trying the claims together will complicate issues and that separate actions will not cause duplication for the court.5 The trial court did not address this issue, as it dismissed the petition with prejudice, but it can consider on remand whether it believes severance would be appropriate for these reasons, as provided by Rule 52.11(a).

IV. CONCLUSION

The trial court erred in dismissing Manitowoc's third-party petition with prejudice. A dismissal for failure to comply with procedural rules is not a dismissal for lack of jurisdiction nor a ruling on the merits of the underlying claim. Further, this Court finds that a party seeking contribution or indemnity need not admit its own fault in its third-party petition but rather can deny liability in its answer to the plaintiff's petition and assert in its third-party petition that if it is liable to the plaintiff, then the third-party defendant is liable to it. The judgment is reversed, and the case is remanded.
