The issue is whether named plaintiffs adequately represent a proposed landowners class in a riverbed-boundary dispute with the state General Land Office when the class would include landowners who settled with the state over the boundary and mineral rights resulting from it. A subsidiary question is whether the state, by its agreement with landowners after the class suit was filed, created a conflict with named plaintiffs. In this case the named plaintiffs, landowners along the Canadian River eastward from Lake Meredith in the Texas Panhandle, lost their effort to certify a class alleging the state took mineral rights when it established new river boundaries for the Canadian below the dam that created the lake. The state argues that the named plaintiffs do not adequately represent the putative class because many landowners along the river in the putative class settled with the state on their mineral rights based on a 1981 survey that fixed the riverís streambed width. The appeals court affirmed the trial court's class-certification denial.
