Fawcett Trust v. Oil Producers Inc. of Kansas

Summary

The court affirmed the denial of the Class's motion to amend, the grant of summary judgment for OPIK on the duty-to-market claim, and the application of equitable estoppel to bar OPIK's statute-of-limitations defense. It held that the prior appeal had already resolved the marketability issue under the law-of-the-case doctrine and that the stipulated conservation-fee damages were not liquidated until the parties entered the stipulation, eliminating any entitlement to prejudgment interest. The court vacated the lower courts' conclusion that a particular oil-and-gas interest statute controlled, while affirming the result on the different ground that the damages were unliquidated.
