Champlin Oil & Refining Company, Petitioners v. M. B. Chastain, Respondents

Summary

The Texas Supreme Court reversed the trial and appellate judgments and remanded for a new trial, holding that Champlin is equitably estopped from denying liability and that the mutual‑mistake claim fails. The Court affirmed the jury’s findings on the estoppel issues and rejected Champlin’s attempt to reform the contract.
