Supreme Court of Missouri

Connie Lange v. GMT Auto Sales, Inc.

March 18, 2025

Summary

The Missouri Supreme Court affirmed the circuit court’s judgment confirming an arbitration award, holding that GMT Auto Sales retained its right to compel arbitration after assigning the retail installment contract, did not waive that right by filing a motion to dismiss, and that the arbitration provision was enforceable because the challenger’s unconscionability claim was unpreserved. The Court applied de novo review to the arbitration issues and relied on established waiver standards.
