Delegation Clauses Require Arbitrators to Decide Validity and Scope Challenges Unless the Delegation Itself Is Specifically Attacked

Case: Karlin vs. UATP Springfield, LLC
Court: Supreme Court of Missouri
Date: 2025-03-04

1. Introduction

This decision arises from a personal-injury lawsuit filed by Karlin after he was injured at Urban Air (UATP Springfield LLC), a “trampoline and adventure park” in Springfield, Missouri. The central dispute was not whether Karlin alleged negligence, but whether his claim must proceed in court or in arbitration under a “Release and Indemnification Agreement” signed on his behalf.

Urban Air moved to compel arbitration based on a Release signed by Karlin’s mother months before the injury. Karlin resisted arbitration on two grounds:

  • Authority/validity: his mother allegedly lacked authority to bind him to the Release’s arbitration terms.
  • Temporal scope: the Release allegedly applied only to incidents occurring on the date it was signed, not months later.

The Release contained an express delegation clause requiring arbitration of threshold disputes about the “scope, arbitrability, or validity” of the arbitration agreement. The case therefore presented a gateway question: who decides Karlin’s authority and scope objections—a court or an arbitrator?

2. Summary of the Opinion

The Supreme Court of Missouri vacated the circuit court’s order denying Urban Air’s motion to compel arbitration and remanded with instructions to compel arbitration. The Court held that because the Release contains a delegation clause and Karlin did not mount any challenge specific to the delegation clause itself, the delegation clause is enforced according to its terms. As a result, Karlin’s challenges to the Release’s validity (his mother’s authority) and scope (its effective term) must be presented to the arbitrator, not decided by the court.

3. Analysis

A. Precedents Cited

1) Missouri framework for compelling arbitration and standards of review

  • Nitro Distrib., Inc. v. Dunn, 194 S.W.3d 339 (Mo. banc 2006) and § 435.355.1, RSMo 2016: The Court reiterated that when there is a factual dispute about the existence of an arbitration agreement, the circuit court must hold an evidentiary hearing, and the party seeking arbitration must prove the agreement exists.
  • Brown v. Chipotle Servs., LLC, 645 S.W.3d 518 (Mo. App. 2022): Cited for the burden of proof and the appellate deference to circuit-court factual determinations on existence (and the citation to Murphy v. Carron, 536 S.W.2d 30 (Mo. banc 1976), as the general standard for reviewing such findings).
  • Car Credit, Inc. v. Pitts, 643 S.W.3d 366 (Mo. banc 2022): Provided the key structural distinction: absent a delegation clause, courts must resolve disputes about an arbitration agreement’s scope/validity before compelling arbitration; with a delegation clause (and no delegation-specific defense), those “threshold” disputes go to the arbitrator.
  • Brown v. GoJet Airlines, LLC., 677 S.W.3d 514 (Mo. banc 2023): Supplied the controlling articulation that a delegation clause is “an additional, antecedent agreement” to arbitrate arbitrability, and that general attacks on the overall arbitration agreement do not prevent enforcement of a delegation clause unless the delegation clause itself is specifically challenged.

2) Federal delegation doctrine incorporated into Missouri analysis

  • Rent-A- Ctr. W., Inc. v. Jackson, 561 U.S. 63 (2010): Quoted for the principle that when a delegation provision exists, a court must treat it as valid and enforce it unless it is specifically challenged—leaving broader validity challenges to the arbitrator.

3) Limiting an earlier Missouri “formation/existence” decision

  • Theroff v. Dollar Tree Stores, Inc., 591 S.W.3d 432 (Mo. banc 2020): Karlin relied on Theroff to argue he need not challenge the delegation clause because, if he wins, there is “no arbitration agreement.” The Court rejected that reliance and confined Theroff to its materially different posture—where the evidence supported a finding that the employee never agreed to arbitrate at all (i.e., a factual nonexistence/formation dispute).

B. Legal Reasoning

The Court’s reasoning turned on a series of characterizations that determine who decides what:

  • Existence vs. validity/scope: Everyone agreed Karlin’s mother signed a Release “on his behalf” and that the document, on its face, purports to cover personal-injury disputes and includes arbitration. Therefore, the Court treated Karlin’s objections as challenges to the Release’s validity (authority to bind) and scope (whether it covered injuries occurring months later), not a factual dispute about whether an agreement existed.
  • Delegation clause as a separate agreement: The Release requires arbitration of “any dispute or claim” including disputes about “the scope, arbitrability, or validity of this arbitration agreement.” Under Brown v. GoJet Airlines, LLC. and Rent-A- Ctr. W., Inc. v. Jackson, that language is a delegation clause—an antecedent agreement assigning “gateway” questions to the arbitrator.
  • Requirement of a delegation-specific challenge: The Court emphasized that Karlin did not raise any defense “unique or specific to the delegation clause.” Because his arguments attacked the Release’s enforceability/coverage generally (authority; term), the court was required to enforce the delegation clause and send those threshold issues to arbitration.
  • Distinguishing Theroff: Theroff involved a legally blind employee who was not informed of the arbitration agreement and did not make (or authorize) the operative acceptance—supporting a finding the agreement never existed as to her. Here, Karlin conceded a signed document exists that purports to bind him; his disputes concern legal effect (authority and construction), which the delegation clause assigns to the arbitrator.
Core operational rule of the opinion: When an arbitration agreement contains a delegation clause covering “scope, arbitrability, or validity,” a party opposing arbitration must specifically challenge the delegation clause; otherwise, the arbitrator decides validity and scope disputes.

C. Impact

  • Strengthening delegation enforcement in Missouri: The decision reinforces that Missouri courts will rigorously apply the “delegation-specific challenge” requirement. Even potentially case-dispositive objections—like lack of authority to bind a minor or an asserted temporal limitation—are for the arbitrator if they fall within the delegation clause’s text.
  • Narrowing the practical reach of Theroff: By emphasizing the “factual existence” nature of Theroff, the Court signals that litigants cannot avoid delegation by relabeling validity/scope arguments as “formation” unless the record truly supports nonexistence (no assent/no authorized acceptance).
  • Recreational waivers and minors: In disputes involving recreational releases executed by parents/guardians, this case indicates that—when delegation language is broad—questions about parental authority and the agreement’s temporal reach are likely to be diverted from courts to arbitrators unless the delegation clause itself is targeted.
  • Litigation strategy consequences: Parties opposing arbitration must plead and support a delegation-focused defense (e.g., unconscionability or lack of assent to the delegation term specifically). Absent that, courts will compel arbitration even where the underlying contract defenses might otherwise be threshold judicial questions.

4. Complex Concepts Simplified

  • Delegation clause: A contract term stating that the arbitrator—not the judge—decides “gateway” issues like whether the arbitration agreement is valid, enforceable, or covers a particular dispute.
  • Arbitrability: Whether a dispute must be arbitrated at all (e.g., whether the contract’s arbitration clause applies to this claim).
  • Existence/formation vs. validity/scope: “Existence/formation” asks whether any arbitration agreement was ever made with the party (a factual assent problem). “Validity” asks whether an existing agreement is legally enforceable (e.g., authority, capacity, defenses). “Scope” asks what disputes and time periods the agreement covers (contract interpretation).
  • De novo review: An appellate court gives no deference to the lower court’s legal conclusions and decides the legal question anew.
  • FAA reference (9 U.S.C. § 1 et seq.): The Release invokes the Federal Arbitration Act, which generally favors enforcement of arbitration agreements and, as applied here, supports enforcing delegation provisions as written.

5. Conclusion

Karlin vs. UATP Springfield, LLC confirms a clear Missouri rule: where an arbitration agreement contains a delegation clause assigning disputes about “scope, arbitrability, or validity” to the arbitrator, a court must compel arbitration unless the opposing party makes a challenge aimed specifically at the delegation clause itself. The opinion also clarifies that Theroff v. Dollar Tree Stores, Inc. is confined to true nonexistence/assent disputes, not to legal challenges about authority or contractual scope when a signed agreement facially purports to bind the party.
