On April 15, 2026, the US Court of Appeals for the Tenth Circuit rejected Gary Binning's appeal to build an additional structure on his property. The court determined that oral promises regarding a guest house lacked sufficient clarity and were unenforceable under state law.
Why it matters
This ruling upholds the enforceability of conservation easements, which are designed to limit development and preserve open spaces. It clarifies that oral representations cannot override the written restrictions established by these legal land agreements.
The 500-acre property is governed by a conservation easement that restricts development to one residential structure per parcel. Plans for a 2,500 square foot wellness centre had been part of the long-running property dispute.
The players
Gary Binning
He is the Wyoming landowner who sought to build additional structures on his property despite existing conservation restrictions.
The Nature Conservancy
This global environmental organization holds the conservation easement and works to protect ecologically important lands and waters.
Teton County
This is the local government jurisdiction in Wyoming responsible for land-use permitting and regulatory oversight.
The details
The court found that Gary Binning's reliance on an alleged oral promise from a Nature Conservancy state director was unreasonable, especially as it conflicted with a prior Wyoming Supreme Court decision. The legal battle began after Teton County approved permits for three auxiliary buildings in 2022 that the court later deemed incompatible with the easement.
Timeline
Teton County approved permits for three buildings in July 2022.
The Tenth Circuit Court of Appeals issued its ruling on April 15, 2026.
Culture Shift
This case reflects the increasing legal rigor applied to conservation easements in areas like the Snake River and Grand Teton National Park. The decision marks a firm adherence to the legal principle of promissory estoppel when balancing private landowner goals with long-term land protection.
Landowners in the area should review their written easements carefully, as this decision confirms that verbal agreements are rarely sufficient to override established deed restrictions. The ruling reinforces that property development plans must strictly comply with existing county permits and conservation terms to avoid lengthy and costly litigation.
The takeaway
This case underscores the importance of obtaining written documentation for any modifications to land-use agreements. Property owners should consult with legal counsel to ensure that any proposed changes are fully compatible with their specific conservation easement terms.
