For those contracts professors who teach Peevyhouse v. Garland Coal & Mining Co., 382 P.2d 109 (Okla. 1962), there is a modern version this 1962 case going on right now in the gas drilling context. In the venerable Peevyhouse case, Willie and Lucille Peevyhouse owned a farm that contained coal deposits, and entered into a contract with Garland Coal & Mining Co. allowing Garland to strip mine the coal, in return for a royalty. In the contract, Garland promise that the land would be restored once they were done.
