FOUR B PROPERTIES, LLC; RANCH 10, LLC; GARY A. BINNING v. THE NATURE CONSERVANCY
The Tenth Circuit affirmed summary judgment for The Nature Conservancy, ruling that an alleged oral promise to allow construction was too indefinite to support a claim of promissory estoppel. The court held that the plaintiffs failed to meet Wyoming's strict proof requirements for a clear promise, reasonable reliance, or the necessity of enforcement to avoid injustice.
